The temperature and humidity of the dust-free room are controlled and adjusted by the combined type purifying air conditioner. However, with the development of technology, especially the development of integrated circuit production technology, the line width of the integrated circuit chip is developed from 0.45 micron to 0.11 micron, even from micron level to nanometer level, and the fine change of the environmental temperature can affect the production process, resulting in the decrease of the yield; meanwhile, the requirement of the production process on cleanliness is high, so that the exhaust air volume in the dust-free room is large, and the control of the overall temperature in the dust-free room is difficult. In summary, such clean rooms require high precision temperature control to eliminate the effect of temperature variations on production.
At present, the total energy consumption of buildings in China exceeds 30% of the total energy consumption of one time, the energy consumption is the first place, the proportion of the energy used by the buildings to the energy consumption of China is still increased year by year, the energy conservation of the buildings becomes one of the key fields of energy conservation of the whole society, and the energy conservation and heat preservation of the external walls of the buildings are one of the key points of energy conservation and consumption reduction of the existing buildings. From the above analysis, it can be known that, in the use process of the clean room, the air conditioning unit needs to strictly control the indoor temperature, and the power consumption of the air conditioning unit occupies more than half of the total energy consumption in the use process of the clean room, so the heat insulation performance of the wall material in the clean room is the key point for energy saving and consumption reduction.
The invention mainly relates to a dust-free chamber with good heat insulation performance, and by designing a wall material for the dust-free chamber with good heat insulation performance, the invention can effectively insulate the interior of the dust-free chamber, is beneficial to high-precision temperature control in the dust-free chamber, eliminates the influence of temperature change on production as far as possible, and can further realize the aims of energy conservation and consumption reduction.
For a further understanding of the invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings and examples.
Example 1
Referring to fig. 1, the clean room of the present embodiment includes an air conditioning unit 1 and a sealed space surrounded by thermal insulation wall boards, wherein a horizontal support platform 3 is disposed at the bottom of the sealed space, and an air inlet cover 2 is disposed at the top of the sealed space, and the air inlet cover 2 is communicated with the air conditioning unit 1 through an air inlet pipe 102; the periphery of the air inlet cover 2 is communicated with the air conditioning unit 1 through an exhaust pipe 103.
In the use process of the dust-free chamber, the air conditioner group is required to strictly control the indoor temperature, one important technical index is the indoor temperature uniformity of the dust-free chamber, namely, the temperature detection is carried out at different positions in the dust-free chamber, and the comparison result shows whether the temperature values at different positions in the chamber are relatively consistent or not, so that the requirement on the consistency of the overall indoor temperature of the dust-free chamber in the production process is met, and the qualification rate and the consistency of products are ensured. The air inlet of the existing dust-free chamber is generally directly positioned right above the air outlet, fresh air flows from the air inlet to the right below, the air outlet positioned right below the air inlet directly exhausts the indoor air, so that the indoor air circulation is carried out, the temperature in the dust-free chamber is controlled within a specified range, the air flow in the dust-free chamber is mainly in an upper-layer flow state and a lower-layer flow state, and air flow disturbance rarely exists between different areas. However, the inventors have found that the above-described air circulation method is not satisfactory in terms of temperature uniformity in the clean room, and how to overcome the problem is a problem that the inventors have paid attention to and studied. In this embodiment, the inventor has found through experimental simulation that the air inlet cover 2 is arranged at the top of the sealed space, the air inlet cover 2 is communicated with the air conditioning unit 1 through the air inlet pipe 102, and the air inlet cover 2 is communicated with the air conditioning unit 1 through the exhaust pipe 103 around, so that the problem of poor indoor temperature uniformity of a clean room can be solved ingeniously, and the specific principle is as follows: as shown by arrows in fig. 1 (arrows in fig. 1 represent air flow direction), fresh air is firstly discharged downwards along the air inlet hood 2 to fill the whole sealed space, then under the suction of the exhaust pipe 103 around the air inlet hood 2, the fresh air flowing downwards is greatly turned in the horizontal direction, and finally flows upwards from the lower side, and is further discharged from the exhaust pipe 103 around the air inlet hood 2.

In this embodiment, the air inlet cover 2 is set up to the passageway that top-down aperture gradually expands, is favorable to the new trend to be the diffusion formula along the air inlet cover 2 of horn mouth form and flows downwards to make the new trend can just begin to fully flow to whole dust free chamber, be favorable to the air mixing of the indoor different positions of dust free, further improve the indoor temperature homogeneity of dust free. In this embodiment, the top of the sealed space is provided with at least eight air outlets, and the eight air outlets are distributed around the air inlet cover 2 at equal intervals in the circumferential direction, so that the air in the dust-free room can be uniformly and symmetrically discharged from the periphery of the air inlet cover 2, and the occurrence of a local air slow-lag zone is avoided. Before determining to adopt the technical scheme of the embodiment, the inventor mainly considers that the temperature uniformity is improved by adjusting the opening angle of the bell-mouth-shaped air inlet cover 2, but finds that the action effect is not obvious. After that, the inventor finds through data simulation and experiments many times, the key of guaranteeing the abundant disturbance of dust-free indoor air, mixing lies in adjusting the ratio between the 2 sizes of air inlet cover and the sealed space size, specifically is: set up the height of the supreme opening of air inlet cover 2 under shed: the height of the sealed space is 1: 6.2-8.4, the aperture of the lower opening of the air inlet cover 2 is 1: 1.4-2.7, the size of the air inlet cover 2 is specifically set according to the numerical ratio, effective disturbance and mixing can be formed on air in a dust-free room, the improvement effect on the temperature uniformity in the dust-free room is remarkable, and the temperature deviation at different positions in the dust-free room can be well controlled within the range of +/-0-0.15 ℃ by adopting the structural design of the air inlet cover 2 in the embodiment through on-site detection.

step A, building a dust-free room: a sealed space is enclosed by the heat-insulating wall boards, and a horizontal support platform 3 with the height of 0.3-0.5 m (specifically, 0.3m in the embodiment) is arranged at the bottom of the sealed space; arranging a suspended ceiling on the top of the sealed space, fixing the air inlet cover 2 on the suspended ceiling, and then installing the air inlet pipe 102, the exhaust pipe 103 and the air conditioning unit 1 to complete the construction of the dust-free room; wherein: the air inlet cover 2 is formed by assembling a plurality of modules (because the air inlet cover 2 has huge volume and is inconvenient to integrally install, the air inlet cover needs to be formed by assembling and combining a plurality of modules);
step B, dust removal: firstly, manually cleaning the interior of a dust-free chamber, then sucking dust in the dust-free chamber through a dust collector, and finally wiping the surfaces of all objects in the dust-free chamber with alcohol at least once;
step C, air purification: introducing filtered and purified fresh air into the dust-free room through the air inlet pipe 102, and simultaneously discharging air in the dust-free room through the air outlet pipe 103 for 1-1.5 h;
d, paving a floor: pouring liquid epoxy resin on the ground of the dust-free room, and after the epoxy resin is solidified, enabling the ground of the dust-free room to form a horizontal epoxy resin coating floor; wherein: graphite powder accounting for 10-15% of the mass of the liquid epoxy resin is added into the liquid epoxy resin (specifically, 10% is taken in the embodiment).

Wherein: graphite powder accounting for 10-15% of the weight of the liquid epoxy resin is added into the liquid epoxy resin, and heat on a floor can be smoothly discharged and static electricity can be reduced through the conductive graphite powder.
Example 5
Referring to fig. 3 to 5, the construction method of the clean room in this embodiment is substantially the same as that of embodiment 4, and more specifically, the thermal insulation wall board includes an inner plywood 1-1, an outer plywood 1-1 and a filler located between the inner plywood 1-1 and the outer plywood 1-1, wherein the opposite surfaces of the inner plywood 1-1 and the outer plywood 1-1 are respectively provided with a convex portion 1-4 and a concave portion 1-5 at equal intervals, and the convex portion 1-4 and the concave portion 1-5 are distributed at intervals.
When the existing heat-insulation wallboard is used practically, the temperature difference of the inner layer splint and the outer layer splint is often huge, and after the existing heat-insulation wallboard is used for a long time, the problem that the inner layer splint, the outer layer splint and the filler are prone to cracking frequently under the action of thermal expansion and cold contraction is also a technical defect existing in the prior art. After the inventor researches the technical defects, the root of the problems is as follows: because the heat-insulating wall board has a strong heat-insulating function, the temperature of the inner layer splint is higher than that of the outer layer splint or the temperature of the outer layer splint is higher than that of the inner layer splint all the year round, and the phenomenon is alternately carried out, and finally the cracking between the inner layer splint and the filler and the cracking between the outer layer splint and the filler are caused after the long-term alternating expansion and contraction effects. In order to overcome the problems, the inventor unexpectedly discovers that the cracking problem between the inner and outer splints and the filler in the thermal insulation wallboard can be effectively overcome by adopting a technical means that the bulges 1-4 and the recesses 1-5 are respectively arranged on the opposite surfaces of the inner and outer splints 1-1 at equal intervals and the bulges 1-4 and the recesses 1-5 are distributed at intervals, and the inventor considers that the inventor can more effectively adapt to the long-term alternating thermal expansion and cold contraction effect of the inner and outer splints by adopting a form that the bulges 1-4 and the recesses 1-5 are distributed at intervals so as to greatly enhance the buffer property between the inner and outer splints and the filler after analysis; moreover, the arrangement of the convex parts 1-4 and the concave parts 1-5 increases the contact area between the filling material and the clamping plate 1-1, so that the binding force between the clamping plate 1-1 and the filling material is improved.
Example 6
Referring to fig. 6, the construction method of the clean room of the present embodiment is substantially the same as that of embodiment 5, and more specifically, support frames 1-2 symmetrically distributed along both sides of the center line of the thermal insulation wallboard are disposed between the inner and outer two layers of plywood 1-1, the support frames 1-2 are rectangular frame structures, and each surface of the support frame 1-2 is connected with a diagonal line through a connecting rod 1-6.
In the embodiment, each surface of the supporting frame 1-2 is connected with the diagonal line through the connecting rod 1-6, so that each surface of the supporting frame 1-2 forms a firm triangular supporting structure, when the filling material is poured, the filling material directly wraps the supporting frame 1-2 in the supporting frame, and the supporting frame 1-2 and the inner and outer layers of clamping plates 1-1 which are symmetrically distributed along the two sides of the central line of the heat-insulating wall plate form a whole. Cold bridges and hot bridges are different laws for the same phenomenon in the south and north: when the building outer enclosing structure conducts heat with the outside, the heat transfer coefficient of some parts in the enclosing structure is obviously larger than that of other parts, so that the heat is intensively and quickly transferred from the parts, the air conditioning and heating load and the energy consumption of the building are increased, the phenomenon of condensation and frost formation of lintels and ring beams of reinforced concrete in winter is commonly seen, and the lintels and the ring beams are called as cold bridges or hot bridges (generally called as cold bridges in the north). In the embodiment, the two supporting frames 1-2 are symmetrically distributed along the central line of the heat-insulating wall board, so that the supporting frames 1-2 do not form a structure which continuously extends along the thickness direction of the heat-insulating wall board, and the generation of cold bridges and hot bridges is effectively avoided.

step four, filling the filler for the second time:
firstly, grinding and crushing a mixture B, wherein the mixture B comprises the following components in parts by weight: 30 parts of waste glass powder, 35 parts of bottom ash after household garbage incineration, 30 parts of slag micro powder and 35 parts of auxiliary agent, wherein the auxiliary agent comprises the following components in parts by weight (namely the auxiliary agent is formed by mixing the following substances in parts by weight): 30 parts of anhydrous sodium sulphate, 25 parts of boron mineral powder, 10 parts of copper ore sand, 25 parts of magnesium chloride, 20 parts of sodium aluminate and 15 parts of sepiolite powder;
putting the crushed mixture B into a stirrer, adding water, and stirring the mixture B for 35 minutes at the rotating speed of 150 revolutions per minute to obtain mixture B slurry;
then, granulating the mixture B slurry to form mixture B particles, controlling the granulation particle size of the mixture B particles to be 2-3.5 mm, and drying the mixture B particles;

At present, the mainstream products of the external thermal insulation materials of the external wall in China are organic thermal insulation materials such as polystyrene foam boards, polystyrene extruded sheets and the like, and the organic thermal insulation materials have the advantages of excellent thermal insulation performance and low price, but have fatal defects, namely, the organic thermal insulation materials belong to combustible materials and have the risk of causing fire. In the prior art, a middle-layer heat-insulating composite wallboard is provided, the heat-insulating function of the composite wallboard is achieved mainly by arranging air holes in the middle layer, in order to improve the porosity of the middle layer, hydrogen peroxide, a foaming agent, egg white and the like are generally used as pore-forming agents in the prior art, but the practical use shows that the ideal pore-forming effect cannot be achieved. The preparation steps of the thermal insulation wallboard adopted in the embodiment provide a brand-new method for forming the holes in the middle layer, and the general process is as follows: firstly, preparing mixture B particles with the particle size of 2-3.5 mm, heating the mixture B particles, scattering the hot mixture B particles on a foam plastic plate in a heat-insulation wallboard mould, ironing staggered through channels in the foam plastic plate, then filling mixture C slurry in the through channels, forming a firm middle layer after the mixture C slurry is solidified, and finally heating the middle layer to evaporate small foam plastic particles in the middle layer and leave stable honeycomb-shaped air holes, so that an ideal heat-insulation effect is achieved; in addition, in the embodiment, the middle part of the heat insulation material is divided into two parts by the middle layer, the heat conductivity coefficient of the middle layer is extremely low, and cold bridges and hot bridges are greatly avoided.
The polytetrafluoroethylene material has the advantages of water resistance, corrosion resistance, weather resistance, high and low temperature resistance and the like, and is widely applied to important departments such as national defense and military industry, atomic energy, petroleum, radio, electric power machinery, chemical industry and the like. In the step one, in the process of manufacturing the splint, polytetrafluoroethylene is added to directly form a waterproof tissue, and polytetrafluoroethylene is doped and matched in gypsum slurry to block capillary channels on a gypsum net-shaped crystal structure, so that water is prevented from being immersed, and the waterproof and moistureproof effects of a gypsum product are improved; the two aspects act together, and the waterproofness of the finished splint 1-1 is greatly improved.
In recent years, the development of the domestic waste incineration power generation industry is rapid, the quantity of the generated waste incineration bottom ash is increased sharply, and the part of the bottom ash is generally directly used for landfill at present, so that not only is the land resource occupied, but also certain pollution is caused to the environment. In the step two, in the preparation of the main filler, the mixture A takes the wastes such as bottom ash, fly ash and slag micro powder after the household garbage is burnt as the admixture, so that the durability and the flame retardance of the main filler are obviously improved, the resource utilization of solid wastes can be realized, and the method has far-reaching significance in the aspects of energy conservation, environmental protection, circular economy and the like.
In the step three, in the primary filling of the filling material, a layer of grid cloth 1-3 is respectively stuck on two opposite side surfaces of the foam plastic board and the support frame 1-2, so that the tensile strength of the contact surface between the finally prepared intermediate layer and the main filling material can be effectively enhanced, the stress can be effectively dispersed, and wide cracks possibly generated on the contact surface between the intermediate layer and the main filling material originally can be dispersed into a plurality of fine cracks, thereby forming the anti-cracking effect; the mesh cloth 1-3 is made of organic or inorganic material such as rock cotton cloth and glass fiber cloth. In the step three, in the one-step filling of the filler, the mixture A slurry (namely the main filler) is filled into the heat-insulation wallboard die twice at different vibration frequencies (low-frequency vibration and high-frequency vibration), so that the mixture A slurry can be more compactly filled in the heat-insulation wallboard die, and the overall strength of the prepared heat-insulation wallboard is improved.
In the step four, in secondary filling of the filler, the hot mixture B particles are scattered on the foam plastic plate in the heat-insulation wallboard die at the vibration frequency of 200-250 Hz, so that the scalded staggered through channels in the foam plastic plate are uniformly distributed in the whole foam plastic plate, the uniform internal structure and the uniform internal pore distribution of the finally prepared middle layer are ensured, and the heat-insulation effect of the middle layer is favorably improved.
The ultrasonic wave has a cavitation effect, and specifically comprises the following steps: when ultrasonic waves propagate in a liquid, small voids are created inside the liquid due to the violent vibration of the liquid particles. These small voids rapidly expand and close, causing violent impact between the liquid particles, thereby creating pressures of several thousand to tens of thousands of atmospheres. The violent interaction among the particles plays a good role in stirring. In the third filling of the filler, when the mixture C slurry is filled into the foam plastic plate along a through channel in the foam plastic plate, the three guided wave probes introduce 27-35 KHz ultrasonic waves into the heat insulation wallboard die, and the ultrasonic waves are used as integral external fields in three directions and applied to the whole filling process of the mixture C slurry, so that the mixture C slurry has a good stirring effect, and a tissue structure with a uniform structure is formed after the mixture C slurry is filled and solidified; particularly, by the cavitation effect of the ultrasonic wave, the small foam plastic particles remained in the foam plastic plate are uniformly separated and scattered, so that the holes left after the small foam plastic particles are evaporated are discontinuous discrete holes, and the heat preservation effect of the middle layer is improved; it should be emphasized that in this embodiment, only by applying ultrasonic wave as external field to the whole process of pouring the mixture C slurry, the discontinuous discrete holes are formed in the intermediate layer, and the above-mentioned effect caused by the cavitation effect of ultrasonic wave is difficult to be achieved by the high-frequency vibration of the ordinary vibration motor.
Electromagnetic waves having a frequency of around 2500MHZ are called "microwaves". The vibration frequency of water molecules in food is about the same as that of microwave, when the microwave oven heats food, the strong oscillating electromagnetic field is generated in the oven, so that the water molecules in the food are forced to vibrate and resonate, the electromagnetic radiation energy is converted into heat energy, and the temperature of the food is rapidly raised. The microwave heating technology is an integral heating technology for the inside of an object, is completely different from the traditional mode of heating the object from the outside, and is an advanced technology which greatly improves the heating efficiency and is very beneficial to environmental protection. And fifthly, in the third filling of the filling material, 2450-2500 MHz microwaves are introduced, the sprayed foam plastic board (namely the middle layer) can be conveniently heated by using the wave heat effect of the microwaves, so that water molecules in the foam plastic board generate high heat due to high-speed friction motion of the wheel pendulum, and then residual small foam plastic particles in the foam plastic board are heated and evaporated, and uniformly distributed air holes are left. (wherein, in the fifth step, other means for heating and evaporating the small foam plastic particles remained in the intermediate layer by heating the intermediate layer may be adopted, for example, the mold of the thermal insulating wallboard can be directly heated by high-temperature steam with the temperature of more than 300℃)
The heat-insulating wall board prepared in the embodiment hardly contains any combustible organic matter, reaches the completely fireproof A1 level, has the comprehensive advantages of heat insulation, sound insulation, high strength, fire prevention, environmental protection, moisture prevention, quick installation and the like, is a novel environment-friendly energy-saving material, and has the heat conductivity coefficient (the average temperature is 25 +/-2 ℃): 0.05-0.08W/(m.k), compressive strength: 15.4 to 20.8 MPa.
Example 8
The construction method of the clean room in this example is substantially the same as that of example 7, and more specifically, a 2mm thick coating a is coated on the surface of the outer clamping plate 1-1, and the coating a is prepared by the following steps: mixing and grinding cerium oxide, aluminum hydroxide, calcium carbonate and iron oxide according to a molar ratio of 4:4:1:2, and calcining the ground powder in an air atmosphere at 1500 ℃ for 180min to obtain powder A; adding a liquid binder accounting for 85% of the mass ratio of the powder A, 20% of a stabilizer, 45% of acrylate resin, 10% of a flame retardant and 9% of a dispersant into the powder A, and mixing to obtain the coating A. (wherein, the coating A has better weather resistance and gloss retention and good color retention after the acrylate resin is added into the coating A, the flame retardant is expandable graphite which is an intumescent flame retardant and has the function of generating large volume expansion or generating a foam substance to cover the surface at a higher temperature to form a stable heat insulation covering layer to play the roles of air isolation and high-efficiency heat insulation, thereby achieving the purpose of flame retardance)
According to the length of the wavelength, the sunlight can be divided into ultraviolet rays, visible light and infrared rays, and the wavelength of the ultraviolet rays is less than 400nm and accounts for about 5 percent of the total solar energy; the visible light wavelength is 400-760 nm and accounts for about 45% of the total solar energy; the infrared ray has a wavelength of over 760nm, which accounts for about 50% of the total solar energy. As can be seen, solar energy is concentrated primarily in the visible and infrared regions. Solar radiant heat enters the room through the sunny side, especially the east and west windows and exterior walls and roofs, causing overheating of the room, and therefore these areas are also critical for the summer insulation of buildings. The higher the reflectivity of the exterior wall coating, the more solar heat is reflected by the exterior wall and the less solar heat is absorbed, i.e., the less heat is conducted to the interior and the lower the air conditioning load in summer. The emissivity of the exterior wall coating A prepared in the embodiment is 0.85-0.92, the surface and internal temperature of a building can be reduced, the exterior wall coating A is particularly suitable for areas which are hot in summer, cold in winter and hot in summer, warm in winter, a low-radiation heat transfer structure is formed, the heat insulation effect of the building structure is improved, and therefore the purposes of reducing the refrigeration energy consumption of an air conditioner and saving energy are achieved.

and step three, mixing the composite powder A and the composite powder B to obtain the cement.
In this embodiment, the specific surface area of the composite powder A is 380-450 m2Per kg, the specific surface area of the composite powder B is 550-600 m2The numerical range of the specific surface area can better improve the activity of the obtained phosphorus slag super-sulfate cement, and the cost is easy to control.
