Description

Method for producing disinfection and antibacterial diatomite plate based on flow meter reading method

Technical Field

The invention relates to the field of sterilization ecological plates, in particular to a method for producing sterilization antibacterial diatomite plates based on a flow meter reading method.

Background

Global warming, along with global warming, rapid economic development of China and continuous improvement of living standard of people, unavoidable decoration pollution is increasingly heavy, and indoor decoration pollution sources are caused: the artificial board, the coating wallpaper, the paint, the latex, the decoration auxiliary materials, various household electrical appliances and other decoration materials can be released along with the change of the temperature and the humidity of the weather, and harmful substances such as formaldehyde, benzene, dimethylbenzene, YVOC and positrons in the air released by the electrical appliances cause harm to the health of human bodies.

At present, a new functional building material for solving the pollution caused by indoor decoration materials is urgently lacking in the market. The novel multifunctional building decoration material is developed to solve the problems of indoor pollution and the like because of the increase of positrons released by indoor household appliances and harmful substances such as pollution and the like brought by indoor decoration materials, which cause harm to the health of human bodies.

In the fiber cement (including calcium silicate) industry, the most used board making machines are the shoveling machine (shown in fig. 2) and the pulp-flow machine (shown in fig. 3). Wherein, the plate making machine is made by the shoveling method, the use history is longest and mature, and the use experience is also most abundant.

Since the appearance of a plate making machine by a pulp flowing method, a lot of people consider that the productivity of the pulp flowing method is higher than that of a plate making method, and the great problems of low productivity and high energy consumption of the traditional plate making machine are solved. Thus, a small tide of pulp flow instead of the shoveling method appears in the world and also in China.

However, the productivity is large, but the final performance of the product is not improved as compared with the traditional product, and the product is slightly reduced, and even the utilization rate of raw materials is reduced. The equipment of the two processes has various characteristics, and is suitable for producing products in different application occasions and products with different performances. Which are complementary relationships to each other rather than alternative relationships, and more rather than updated relationships. As a result, the increased portion of capacity and the reduced portion of energy consumption cannot be balanced with the lost portion of performance and raw material utilization, and even impact the product's utility and sales price.

In order to compare the difference of products produced by the two processes, in order to more reasonably utilize and use the two processes, under the condition that all raw material conditions are the same, the same formula, the same pretreatment, the same pool treated fiber (SR takes the arithmetic average value of the optimal required values of the two processes), the same pre-curing and steaming degree and the same equipment for pulp flow and pulp copying are used for production at the same time; the dehydration proportion of each process control point in the production process is the same (but the slurry discharge concentration is executed according to the respective process specification), and the production treatment means with the same water content of the finally formed wet blank is controlled; the performance evaluation of the produced medium density finished product is shown in figure 18. The performance evaluation of the low density product produced is shown in FIG. 19.

From the comparison of fig. 18 we can see: in addition to the aspect ratio, the medium density finished products produced by the shoveling method are closer to ideal values than those produced by the pulp flow method. And comprehensively evaluating that the comprehensive performance of the finished product produced by the medium-density product by using a papermaking method is about 10% higher than that of the finished product produced by using a pulp flow method.

From the comparison of fig. 19 we can see: when the low-density product is produced by the shoveling method, the specific strength, density, aspect ratio and elastic modulus deviate from ideal values greatly. In contrast, when a low density product is produced by the pulp flow method, the properties except the water absorption and the surface flatness are closer to ideal values than the finished product produced by the shoveling method. And comprehensively evaluating that the comprehensive performance of the finished product produced by using the flow pulp method of the low-density product is about 5% higher than that of the finished product produced by using the papermaking method.

This experiment was repeated under different seasons and different climatic conditions to obtain an excessive number of results. From this point of view, it can be considered that: the two processes of the shoveling method and the pulp flowing method are complementary. The method is more suitable for producing products with higher density, and the high fiber utilization rate is a characteristic of the method process, and is enough to make up for the loss caused by high energy consumption of the shoveling equipment under the condition that the price of the current fiber raw material is high and the price of electric energy is not greatly increased. The flow pulp process is more suitable for producing products with lower density.

The conclusion can be made that some end-effect can be seen by analyzing the difference of the water content of the materials by the shoveling method and the pulp flowing method and the dehydration method thereof. First, look at the change in water content of the product produced by these two processes from raw material to finished product:

from the above table, it can be found that the "raw material water content" and the "finished product water content" are identical. That is, all the changes in the moisture content throughout the manufacturing process are due to the artificial addition of different moisture due to the process requirements. At the same time, it was found that even after the autoclaving, the pulp flow method was good and the water content was the same. The moisture content of the wet preform was not greatly different although the difference was found. The place where the maximum water content difference occurs in both processes is where the slurry concentration is controlled.

Since the water contents of the materials at the beginning and the end of the two processes are the same, and the places where the water contents of the materials of the two processes are obviously different are in the middle process sections, it can be confirmed that: the two processes employ different dewatering methods or different amounts of dewatering. Therefore, consider again the dehydration mode of these two processes:

For conventional devices:

for the reform device:

whether the device is changed or the traditional device, the dehydration modes of the device are three in general, namely: firstly, naturally dehydrating; secondly, squeezing and dehydrating; and thirdly, vacuum dehydration.

In the traditional machine, the press dehydration with the pressure-adjustable couch roll is mainly used, the natural dehydration is auxiliary, and almost no air passes through the material layer in all dehydration processes. For traditional pulp flowing equipment, vacuum dehydration with adjustable pressure is mainly used, rolling dehydration and natural dehydration are used as auxiliary materials, and a large amount of air passes through a material layer in a vacuum dehydration link.

So-called reform equipment, in the shoveling process equipment, a vacuum dehydration means is added, the dependence on the extrusion dehydration of a couch roll and the natural dehydration of a wire wheel is reduced, and a small amount of air passes through a material layer; in the improved pulp flow method equipment, although other dehydration means are not added, the number of the vacuum sucking discs is increased. The total amount of dehydration before and after the reformation is not changed obviously, but the dehydration amount of a single vacuum chuck is reduced.

From the above analysis and the actual operation, it was found that: the water consumption of the shoveling method is larger than that of the pulp flowing method; the same products are produced by the equipment of the shoveling method and the pulp flowing method, and the product performance and the appearance are obviously different.

However, both the shoveling method and the pulp flow method are good, and the aspect ratio of the finished product is always in a certain proportion to the linear velocity of the blanket. In particular, the wire velocity of the felt is more sensitive to the machine than the pulp flow method. The reason for this is understood to be that the movement speed of the slurry is different from the linear speed of the moving member for receiving the slurry, and the fibers on the surface of the slurry, which have the same movement speed as the slurry, are affected by the movement of the receiving member having the different movement speed as the slurry at the moment of the slurry adhering to the receiving member under the combined action of external factors such as friction force, movement inertia, viscosity, joint angle, movement direction, angle and the like of the slurry, and part of the fibers are changed from the original aligned direction in the slurry to be rearranged under the action of the external force.

Referring to fig. 4, this phenomenon occurs at the intersection of the wire wheel and the slurry in the machine, and a process of "maximum pressure-pressure near disappearance-maximum pressure" is performed. The motion kinetic energy of the slurry disturbed by the stirrer in the net cage affects the arrangement of the fibers, the distribution of the powder particles and the relative positions and relations of the fibers and the powder particles, and the rotating power of the net wheel is from the friction force of the blanket, so that the mass and the rotating resistance of the net wheel cannot be very small. Therefore, there is a partial rearrangement of the fibers that occurs at the entire intersection of the wire wheel and the felt.

Whereas the pulp flow device only has the phenomenon that the fibers are rearranged at the junction of the pulp discharged at the outlet of the pulp flow opening and the blanket. The fiber rearrangement phenomenon is related to the discharge speed, angle, flow, concentration of slurry and the movement speed of blanket on the pulp flow method equipment, and the distribution of powder particles, the relative position and relation of the fiber and the powder particles are related to the parameters such as the magnitude of vacuum dehydration negative pressure, gradient change and the change direction of the gradient change.

Referring to fig. 5, the total unit material layers of the slurry method are much smaller than those of the papermaking method, or the thickness of the single material layers is thicker than those of the papermaking method. Thus, when using relatively short fibres, a part of the fibres may be arranged at a relatively large angle, even perpendicular, to the direction of movement of the felt, resulting in a so-called three-dimensional arrangement of fibres. When the individual layers are relatively thick, this provides a possible space for the three-dimensional arrangement of fibers. When the building light plate is used as a wall body and a suspended ceiling, the requirements on compressive strength and tensile strength in the direction perpendicular to the breadth are not high, and even the building light plate is not utilized. This means that the portion of the fiber parallel to the Y-axis or nearly parallel to the Y-axis is wasted in practical applications. The requirements on the longitudinal strength, the transverse strength and the longitudinal tensile strength in the width direction parallel to the X axis and the Z axis are high, and even the decisive requirements are high. Therefore, the above-mentioned problem of the utilization of the fiber raw material occurs. This is one of the reasons for the lower utilization and lower specific strength of the product fibers produced by the headbox apparatus.

The total number of unit layers in the machine is related to the number of wire boxes that the machine is made up of, in addition to the number of revolutions of the forming drum. Because the net wheel in the net cage filters water by utilizing the pressure difference acting force when the slurry is shoveled, the pressure difference acting force, the water filtering capability, the water filtering time and the water filtering acting distance are all limited, and a very thick material layer cannot be carried out. The differential pressure acting force is directly acted on the fibers at first, the acted fibers are pushed by pressure to the mesh cloth to increase the filtering resistance of the mesh cloth, and the fibers influenced by the acting force almost bear the differential pressure acting force in the direction of the largest area, namely, almost lie on the surface of the mesh cloth, so that the loss of powder particles is prevented to the greatest extent, and the mixture of the fibers and the powder particles is formed. Therefore, the fibers are arranged in a direction perpendicular to the web, with a low probability of being almost negligible. Thus, most of the fibers of the product produced by the papermaking method equipment are almost parallel to the width direction of the product, the fiber utilization rate is improved compared with that of the product produced by the pulp flow method equipment, and the specific strength is correspondingly improved.

As mentioned above, the consistency (or concentration) of the slurry is one of the influencing factors in this case. Therefore, the different felt line speeds should be matched to different slurry viscosities, either by the handsheet or by the headbox process, to reduce the effect of the fibers being rearranged. As regards the importance of the aspect ratio, this is mainly reflected in the application of the product. As mentioned above, the building boards are mainly applied to building walls and ceilings, are parallel to frameworks made of various materials and are fixed on the frameworks to form a so-called wall or a ceiling together.

Therefore, mechanical parameters such as flexural strength in the longitudinal and transverse directions and elastic modulus in the longitudinal and transverse directions of the product are very important. The optimal aspect ratio (longitudinal strength: transverse strength) is 1, the product strength at this time is the same or very similar in all directions on a plane, and the application direction of the product is not limited. If the aspect ratio is too small, e.g., only 0.5, it means that the transverse strength is doubled over the longitudinal strength. The product is severely restricted in practical application, and to fully exert the performance of the product, designers and construction workers have to use the product with the maximum strength direction perpendicular to the direction of the minimum distance of the arrangement of the frameworks. Otherwise, designers and construction workers would choose to choose thicker such products to meet the surface active load requirements. The method has the advantages that the mechanical property of the product is low, the resource waste is caused, the construction cost is improved, and the wall or the suspended ceiling with the same mechanical property can be obtained only by more silver on the construction side.

Generally, building light board walls and ceilings in all parts of the world are combined by plates and frameworks to form the walls or ceilings. In order to save the construction cost, the plate is often installed by the same method as the method of maximizing the long side direction of the plate and the frame support distance. If a light plate partition wall is required to be built in a certain project, a building light plate with lower longitudinal and transverse resistance just happens, the long side direction of the plate is mutually perpendicular to the trend of the maximum framework supporting distance, so that the requirement of the movable load on the surface of the plate is met by utilizing the maximum strength direction of the plate. However, only a slightly thicker sheet material may be selected.

The low aspect ratio not only affects the mechanical properties of the product, but also causes the expansion shrinkage difference of the product in the X-axis and Z-axis directions to be increased. The shrinkage of the product in different directions is greatly inconsistent, and the cracking phenomenon of the joint between the plates is easy to occur. The low aspect ratio also means that the difference of elastic modulus in the aspect direction is large, and deformation of a built wall or ceiling is easy to occur in the use process.

In order to increase the productivity of the machine and blindly increase the linear velocity of the felt, the linear velocity of the felt is increased to increase the productivity without correspondingly adjusting the relevant production control parameters of the slurry concentration, the cage stirring speed of the machine, the pulp discharging speed of the pulp flow machine and the like. The resulting phenomenon of low aspect ratio of the product cannot be unnoticed.

Indeed, the improvement in productivity is directly related to the linear velocity of the blanket motion. The final thickness of the product is formed by multiplying the total material layer by the thickness of the single material layer, namely the final thickness is formed by multiplying the rotation number of a forming cylinder by the thickness of the single material layer; the maximum linear velocity of the forming drum is almost equal to the linear velocity of the felt, i.e. the linear velocity of the felt directly influences the formation time of the final thickness. Thus, the faster the felt line speed, the shorter the formation time of the individual layers; the faster the linear velocity of the blanket, the faster the linear velocity of the forming drum; the faster the linear speed of the forming drum also means that the shorter the time to complete the final layer thickness. Thus, by increasing the linear velocity of the blanket, the throughput is increased.

The problems are: if the linear velocity of the felt is merely increased without having other related production control parameters also increased synchronously, it is meaningless to increase the linear velocity of the felt, which only causes an undesirable fibre arrangement. The most direct expression of the non-ideal arrangement of the fibers is that the aspect ratio and modulus of elasticity of the product are above. The lower aspect ratio and elastic modulus means that the product performance is reduced, and the application range of the product is narrowed, and even the use effect is affected. At the same time, the utilization rate of materials (including raw materials, energy sources, transportation and finished products) is low, and even the materials are difficult to utilize.

From this it can be seen that: both processes must increase the dewatering speed or enhance the dewatering capacity simultaneously while increasing the felt speed, which is common to both processes; the wire-drawing method also requires an increase in the wire speed of the wire wheel, the power of the wire wheel rotation being from the felt, that is to say the wire wheel speed is increased simultaneously when the felt is accelerated, but the wire wheel mass is large, and insufficient friction or the wire wheel rotational resistance must be taken into account, so that an adjustment of the couch roll pressure is necessary to improve these conditions. The wire speed of the net wheel is improved, besides the slurry in the net cage can be rolled under the action of a stirrer, no equipment of one manufacturer can control the slurry flow field in the net cage at present, and the phenomenon of fiber rearrangement in the shoveling method is just on the net cage, the net wheel and the net cloth. Therefore, unless this problem is solved, the machine of the shoveling method only has the step of sacrificing the mechanical properties of the product in order to increase the line speed. This is the bottleneck limiting the productivity of the machine, and is the important point of attention when the machine increases the felt speed. The pulp-flowing method also needs to adjust the pulp concentration or viscosity, the pulp-discharging speed, the pulp-discharging angle of the pulp-discharging opening, the vacuum dehydration pressure, etc. This is the important point that the head stock method must pay attention to in increasing the felt speed.

Generally, the pulp flow method has higher feasibility of improving the linear velocity of the blanket than the papermaking method, and is easier to adjust and operate. Therefore, the pulp flow method has higher productivity than the papermaking method because of thicker single material layer, and has higher feasibility of increasing productivity again by increasing the linear speed of the blanket than the papermaking method at the same time of realizing higher productivity under the same linear speed. Of course, the shoveling method can increase the thickness of a single material layer by increasing the differential pressure acting force, and can also increase the productivity under the condition of unchanged linear velocity of the blanket. Some congenital, almost unresolved (at least for me) drawbacks of the pulp-flow process can also be avoided.

The method is designed between a papermaking method and a pulp flowing method, and the method for making the best of the advantages and the disadvantages of the two processes is adopted, so that the advantages of the two processes are utilized as much as possible, and the disadvantages of the two processes are avoided to the greatest extent. It is a very good proposal, even the equipment can be used for producing products with different densities, and the productivity similar to that of the pulp flow equipment can be obtained, and the comprehensive performance of the products can be maximally similar to that of the shoveling method.

The industry has been striving to be good for either the shoveling process or the pulp-flowing process. One of the most important issues is the difference in capacity. It can be almost certainly said that the same recipe, the same raw material and pretreatment are used according to the different regulation methods of the two different processes at the same carpet line speed. The pulp flow method has the advantages that the productivity can be higher than that of the shoveling method due to the problem of the thickness of a single material layer, and the equipment operation energy consumption is lower than that of the shoveling method.

In order to increase the dewatering speed of the pulp-flowing method, it is easier than the pulp-taking method, and it is not difficult to increase the pulp-discharging speed. It is difficult to control how precisely it is synchronized. At present, no equipment capable of solving the problem that the vacuum degree is influenced by the slurry concentration, the material layer thickness and the blanket water permeability and often fluctuates is still available.

Currently, it is believed that increasing the diameter of the forming drum increases the throughput. In fact, the productivity is not related to the diameter of the forming cylinder at all. The time consumed by the large-diameter forming cylinder to be one after each ejection exceeds one of the small-diameter forming cylinders, and the time required by the large-diameter forming cylinder to form each wet blank is almost the same as that of the small-diameter forming cylinder, and is directly related to the linear speed of the blanket, and the relationship with the diameter of the forming cylinder is very little and can be ignored. When evaluating the productivity of a board machine in China, whether the board machine is a shoveling machine or a pulp flowing machine, the expression is that: every year, ten thousand square meters are x. Then note the conditions: refers to a flat plate with the thickness of X mm. Different formulations, different raw materials, different slurry viscosities, different concentrations, etc. will all affect the linear velocity of the felt. That is, the capacity of the plant is affected unless the conditions add: refers to a specific formulation, specific raw materials, concentrations, etc.

In general, the final layer thickness (whether by a shoveling method or a pulp-flowing method) before the upper forming drum is between 1.2 and 0.5 mm, and the most common single layer thickness is between 0.6 and 0.8 mm. Assuming that the annual energy production of a device is 300 ten thousand square meters, it is calculated what its blanket speed should be:

assuming that a certain formula is matched with certain specified raw materials, the optimal single layer thickness on certain equipment is 0.7 mm; suppose a device is operated for 11 months throughout the year (the whole set of device is overhauled and spring festival is vacated every year); assuming that a certain device operates for 28 days on average per month (accumulated shutdown for 2-3 days per month for blanket replacement, maintenance); suppose a device is operating 24 hours a day (three-shift or four-shift three-shift operation); producing a product with the width of 1220 multiplied by 2440 mm and the maximum length of a wet blank is 2500 mm (domestic popular metering method).

1. Calculating the total product material layer, the total material layer length and the finished product breadth area:

the produced thickness flat plate with the thickness of 6 mm is formed, and the total number of the layers is=6 mm/0.7 mm=8.57 mm and approximately 9 layers; namely: the 6 mm flat plate is formed by: a block of total length=2500 mm×9 layers=22500 mm=22.5 m layers, the layer thickness=0.7 mm, every 2500 mm in the length direction of the layers is cut into 9 layers of 2500 mm in total, namely, the layers are stacked; a layer/plate of 22.5m overall length; finished product area=1220×2440 mm= 2976800 mm 2= 2.9768 square meters/Zhang square meters/sheet.

2. Calculating the production time of the single slab:

annual plant run time = 11 months x average monthly 28 days x 24 hours per day x 60 minutes per hour = 443520 minutes per year; average production time per slab= 443520 minutes/year/300/3 square meter/year) = 0.44352 minutes/sheet×60 seconds≡26.6 seconds/sheet.

3. Calculating the linear speed of the blanket:

forming drum linear speed = blanket linear speed = layer of 22.5m total length/Zhang 26.6.6 seconds/sheet = 0.85 m/s = 50.75 m/s +.100% ≡51 m/s of wet blank forming rate.

If the yield of the wet blank is only 80-90%, the linear speed is required to meet the annual energy production of 300 ten thousand square meters: the forming drum linear speed=the blanket linear speed=the material layer of 22.5m total length/Zhang 26.6.6 m/sheet=0.85 m/s=50.75 m/s/wet blank forming rate 80% -90% ≡ 63.44-56.39 m/s.

From the above calculations, it can be seen that: the felt linear velocity was 51 m/s. The product specification index of the equipment manufacturer is also normal.

However, in the use of daily equipment by users, it is difficult to avoid equipment failure, the blank forming rate of wet blank is difficult to achieve 100% (in fact, 90% of the average day can be achieved well), and the like, so that the finished product is not to mention. In practice, although the aspect ratio can be guaranteed to be within a reasonable range (all process points are controlled and are within a normal range) by the production at the linear speed of 51 m/s, when the yield of wet blanks is only 80% -90%, the linear speed of the blanket is up to 63.44-56.39 m/s in order to meet the annual yield of 300 ten thousand square meters, and the design goal of the design product is difficult to meet the finished product. Therefore, on the premise of meeting the product performance, the actual yield of the equipment can reach 80% of the design yield, which is quite good.

For this reason, it is mistaken that the yield of the finished product does not reach the design yield because the equipment speed is too slow, so that the line speed is blindly increased to make the actual yield reach the design yield requirement. If the linear speed of the blanket is increased to 20-30%, the speed reaches 64-72 m/s, and if other related measures cannot be synchronously met, it is difficult to obtain a finished product with seriously influenced performance and severely fluctuated quality.

In fact, there have been businesses abroad that increase the linear velocity of carpets to 90 meters/second for production, even at speeds of 110 meters/second. However, the equipment should be fully automatic or even microcomputer controlled, and various measures and equipment should be provided to match the operation of the plate making machine, otherwise, it is difficult to make good products. It is known that, despite the fact that such a high speed is available, there is no practical example of such a speed for commercial production.

Some domestic enterprises (using imported equipment, with quite high automation degree and microcomputer control) have tried to test the production of 90 m/s for a short time, but the produced products are not enough.

It can be said that the machine for making the blanket is to increase the speed of the blanket to 90 m/s, making the blanket is difficult and almost impossible without other aspects of the cooperation; the pulp flow method equipment is much easier than the shoveling method equipment when the speed of the blanket is increased to 90 m/s, but the performance and quality of the product can not be guaranteed, the linear speed of the blanket of the light increasing equipment is increased, and other relevant coordination is not finished, so that the performance of the finished product can be seriously influenced. This is natural law. Even if the influence of the attraction force can be eliminated, the tension influence cannot be overcome.

To sum up:

the pulp flow method and the papermaking method have the characteristics of each, and each has a finished product density range which is most suitable for production;

the yield of the pulp flow method is easier to be improved than that of the papermaking method, but the comprehensive performance of the finished product is slightly lower than that of the papermaking method when the same product is produced;

neither the pulp-flowing method nor the shoveling method is good, the productivity is not improved by singly improving the linear speed of the blanket, and the synchronous matching with other process control points is needed.

Thus, a new process combining the two advantages is currently needed.
