Description

Manufacturing process of functional tongue type balls

The present invention relates to a functional tennis ball manufacturing process, and more particularly, unlike the conventional high-temperature firing method using natural ore, the particles are connected to the particles in a hot air drying method of 150°C to 170°C. It relates to a functional tennis ball manufacturing process having durability that does not loosen or collapse even under the pressure and flow rate of water while continuously maintaining the characteristics and functions of ore as it is.

In general, ceramic balls used domestically and internationally are used as functional materials in many products, and are widely used for purifying and purifying water as well as for removing heavy metals. In particular, it is used as a material to achieve a change in physical properties in addition to the use of improving the refreshing sensation of water or increasing the absorption rate.

Domestically and externally, most of the manufacturing processes of ceramic balls for each natural ore have been sintered at high temperature (1050℃~1100℃) or at 700℃~800℃ corresponding to medium temperature. The reality is that they are producing ceramic balls that have only a simple far-infrared radiation function, not fulfilling the specific performance and function of ore. As an example of a prior art for such a ceramic ball manufacturing method, Korean Patent No. 10-0940930, which is the following patent document, describes a method of manufacturing a spherical ceramic ball by a rotation method.

The ceramic ball forming process is also generally produced in a similar manner.

A certain amount of the seed ball is placed in a rotating drum (molding) machine, and water is finely sprayed on the seed ball in a molding machine that rotates at an average speed of 25 to 30 rpm, and the prepared mixed ore powder is sprayed evenly. ) To grow.

After 12 hours of natural drying process along with the wind of a fan, the ceramic balls formed by the above method are transferred to a drying machine, and a certain amount of ceramic balls are placed in a fireproof container and distributed and laminated on a firing rail to prepare an electric firing machine or bancassee oil. It is pushed into a furnace for fuel and fired while gradually increasing the temperature step by step. However, depending on the type of ore or the characteristics of the ceramic ball, sintering may be varied at a temperature of 700°C to 800°C or a temperature of 1050°C to 1100°C.

As described above, any ore that can be produced as a durable ceramic ball with only fine ore powder and water contains as much as 40% to 25% of silicon dioxide (SiO2) components. That is, the melting point of silicon dioxide melts in a glass state when it is heated above 600℃~700℃. As a result, when heat is received at 1050°C to 1100°C for a long time, a link structure between the raw materials is formed up to the center of the ceramic ball, thus making it possible to manufacture a durable ceramic ball. Currently, there are several types of ores that must be produced with ceramic balls, but only about 30 types of ores used as water-related materials are among them, and the characteristics and functions of ores vary depending on the temperature (heat) of most.

However, tourmaline ore, also known as tourmaline, loses electric power when heat (temperature) above 600℃ is applied. Magnetite ore also loses its function due to the loss of reducing power at high temperature, and when zeolite ore containing a lot of silicon dioxide (SiO2) is heated above 600℃, the surface of the ceramic ball becomes vitrified and the function of porosity is lost. As a result, only far-infrared radiation and energy dissipation functions are provided, and multipurpose functions and properties cannot be obtained due to loss of adsorption and absorption functions.

In particular, raw materials sensitive to the firing temperature (heat), including antibacterial materials, dechlorinated materials (Caso₃), reducing materials (Mg), and activated carbon powders, cannot be produced with ceramic balls of functional materials.

As described above, conventionally, since ceramic balls are fired at high temperature (1050° C. to 1100° C.) or medium temperature (700° C. to 800° C.), raw materials sensitive to firing temperature (heat) cannot be manufactured into functional ceramic balls.

Patent Document: Registered Patent No. 10-0940930 (Registration Date: 2010.01.29)

The functional tennis ball manufacturing process of the present invention manufactured as described above will be described in detail step by step as follows.

Step (a)-making ore raw material

It makes the raw material of ore in powder form of 200~500 mesh. At this time, the raw material particle size can be produced in the form of a powder of 200 to 500 mesh, but according to the present invention, the ore raw material in step (a) is processed so that the moisture content does not exceed 7%. If the moisture content of the ore material exceeds 7%, there is a possibility that cracks may occur during firing, and the firing time may take a long time.

(b) Step-Injecting the ore raw material into the molding machine

Put the ore raw material made in step (a) into a molding machine to make a spherical body. At this time, according to the present invention, the amount of the ore raw material injected into the molding machine in step (b) is 35% input to the volume of the molding machine.

Here, as an example, it is preferable to put about 35 kg of ore raw material into a molding machine with a capacity of 100 kg. At this time, if the amount of ore raw material input to the molding machine with a capacity of 100 kg is less than 35 kg, the ore raw materials do not roll in the molding machine and are not formed.

Step (c)-forming a tennis ball

One). The rotational speed of the molding machine is set to 15~25rpm and slowly rotated clockwise. The binder liquid prepared in the ore raw material rotating in the molding machine is sprayed with an air spray gun. In this case, if the spraying method is not sprayed like a mist, the ore raw materials are aggregated in the binder liquid moisture, and a uniform spherical body cannot be formed.

2). When the binder liquid particles rotate and contact the rotating ore raw material, a very small and fine lump is formed, and gradually becomes spherical in the molding machine rotating at a speed of 15 to 25 rpm.After about 48 hours, the whole ore raw material injected is very fine. It is molded into a shape seed ball.

3). By spraying the binder liquid onto the rotating seed ball appropriately and spraying the prepared ore raw material on the surface of the small spherical body moistened with the binder liquid in the molding machine, it is molded into the size of the planned tennis ball through continuous repetition. At this time, a binder liquid should be finely sprayed onto the seed ball in the rotating molding machine, spraying the prepared ore raw material on the moistened spherical body as if scattering it, so that it adheres evenly to the surface of the spherical body and tightly adhered to it by the continuous rotational force. In this way, the work of increasing the pie (Ø) of the tennis ball must be completed by repeating the work until it is large to the desired size.

Here, according to the present invention, the binder liquid in step (c) is used by selectively selecting polyethylene (PE), polypropylene (PP), or acrylic resin as an organic binder, and emulsifying it with water and a natural surfactant (soy lecithin). It features. At this time, as a preparatory step for the completion of the functional tennis ball, in addition to polyethylene (PE) resin and polypropylene (PP) resin, which are organic binders, acrylic resin, etc. can be selectively used, but a natural surfactant (soy lecithin) must be used with water. It should be emulsified and mist sprayed with an air spray gun should be employed. This is because if the provider liquid is not sprayed finely like a mist, the ore raw material is aggregated in the binder liquid moisture and cannot be formed into a uniform spherical body. Meanwhile, according to the present invention, the binder liquid may be formed of multi-layered porosity by selectively applying polyethylene (PE), polypropylene (PP) or acrylic resin.

Step (d)-Drying the tennis ball

In the drying step, take out the spherical tennis ball from the molding machine and let it air dry in a shaded place. At this time, according to the present invention, in step (d), the tennis ball is naturally dried for 48 hours.

(e) Step-Primary drying and firing of the tennis ball

The dried tennis ball is dispersed in a refractory ceramic container, placed in a far-infrared fire extinguisher, and fired by hot air drying. At this time, the far-infrared ray sinterer smoothly operates the air inlet at the bottom and the hot air control outlet at the top to evaporate organic matter and moisture generated by the binder and water to fire a safe and solid tennis ball.

Here, in order to produce a multi-purpose functional tennis ball, first, a far-infrared sintering machine is prepared and the sintering method is changed with a hot air drying method rather than using a furnace kiln using generally used banker oil as fuel. It can make the production of balls possible.

In the present invention, unlike a generally used electric furnace (kiln), a deep center in which an air inlet control device and a hot air control outlet control device that can penetrate outside air as well as moisture removal that can concurrently perform a hot air drying process are embedded It uses a far-infrared sintering machine that receives heat from and transfers heat to the surface. At this time, the air inlet of the far-infrared fire extinguisher is closed to prevent external air from entering during thermal drying, and the air inlet of the far-infrared fire extinguisher is opened so that external air is introduced during hot air drying.

In step (e), the dried tennis ball is dispersed in a refractory ceramic container, placed in a far-infrared fire extinguisher, and first dried and fired in a thermal drying method at 50°C.

(f) Step-Second firing of the tennis ball

While gradually raising the temperature of the far-infrared ray calciner to 120° C., the second calcining is performed using a hot air drying method. At this time, the reason for drying with hot air while gradually raising the temperature of the far-infrared sintering machine is because first, when bubbles are generated in the binder liquid bound to the tennis ball during rapid heating, the bonding force decreases and the durability is weakened. Second, it is possible to stabilize the evaporation of organic substances in the resin binder liquid phase.

(g) Step-3rd firing of the tennis ball

While maintaining the final temperature of the step (f) as it is 120 ℃ extends the firing in a hot air drying method. This is to ensure that moisture is almost vaporized out of the binder and water used for forming the tennis ball and only the ore raw material remains. In other words, as moisture vaporizes, a number of pores and cross-channels are formed, thereby increasing the specific surface area of the functional tennis ball, thereby enhancing the absorption and absorption functions in water and air.

(h) Step-The fourth firing of the tennis ball

According to the performance of the functional tennis ball to be produced as the final firing step, the temperature of the far-infrared firing machine is adjusted to 150℃~170℃, followed by a firing process in a thermal drying method without final air inflow and evaporation, and then cooled. At this time, the reason for setting the temperature of the far-infrared ray calciner to 150℃~170℃ is to obtain the antioxidant effect of components weak to heat among the unique characteristics of the ore.

Here, according to the present invention, in step (e), the tennis ball is first dry-fired for 1 hour, in step (f) the tennis ball is fired for 2 hours, and in the step (g), the tennis ball is baked for 1 hour. The third firing is performed, and in step (h), the tennis ball is fired for 2 hours and 4 times, and after the fourth firing, the current of the far-infrared firing machine is cut off and left for 3 hours to gradually cool to complete the tennis ball. .

(Hot air drying firing) division Temperature(℃) time step (e) 50 One step (f) 120 2 step (g) 120 One step (h) 160 2

In step (e), as shown in FIG. 1, if the temperature of the far-infrared sinterer is adjusted to 50°C and a current is applied, the temperature of the far-infrared sinterer is maintained at 50°C after 10 to 15 minutes. The primary dry firing is carried out for 1 hour while maintaining 50°C.

In step (f), if the temperature of the far-infrared burner is set to 120°C, the temperature of the far-infrared burner is maintained at 120°C after 10 to 15 minutes, and the temperature of the far-infrared burner is maintained at 120°C for 2 hours. During the second firing.

In the step (g), the temperature of the far-infrared ray burner is maintained at 120° C., and the third firing is performed by extending for 1 hour.

In step (h), if the temperature of the far-infrared sinterer is set to 160°C, the temperature of the far-infrared sinterer is maintained at 160°C after 10 to 15 minutes, and the temperature of the far-infrared sinterer is maintained at 160°C for 2 hours. During the fourth firing.

In this way, in the first drying firing, it is heat-dried at a low heat of 50°C for about 1 hour, and in the second firing, it is fired in a hot air drying method in a heat of 120°C for about 2 hours. The reason why it should be fired in a hot air drying method while gradually increasing the temperature is that bubbles may occur in the binder liquid bound to the tennis ball during rapid heating. At the same time, having a sintering method in the hot air drying method smoothly operates the air inlet at the bottom of the far infrared ray sinterer and the hot air control outlet at the top to evaporate organic matter and moisture generated by the binder and water to complete a safe and robust tennis ball. I want to make it.

The third drying and firing in the same manner as described above, after firing in a hot air drying method with heat of 120°C for about 1 hour, and then raising the temperature with heat of 150°C to 170°C and repeating the firing in a heat drying method for about 2 hours. The organic material and moisture generated from the binder and water used in the process evaporate and fly away, leaving only the role of a binder linking the ore raw material, and forming a number of pores and cross-channels in the tennis ball itself to increase the specific surface area to increase the function of the tennis ball. Not only can it increase to the maximum, but it can also produce high-quality tennis balls with elasticity and durability.

In this way, the hot air drying method using a far-infrared calcination machine connects the particles of the ore raw material to the particles to increase the strength of the tennis ball to have durability.

On the other hand, according to the present invention, there are several types of ores that need to produce functional tennis balls by low-temperature firing, but among them tourmaline ore, magnet iron ore, ferrite ore, antibacterial material, dechlorination material (caso₃), and reduction Materials (Mg) are materials sensitive to the firing temperature (heat). However, the hot air drying method using a far-infrared ray firing machine not only enables the production of functional tennis balls, but also enables the production of activated carbon powder as durable tennis balls. As a result, the application range can be expanded to products related to water and air.

As described above, when the functional tennis ball manufacturing process of the present invention is applied, the production of functional tennis balls having a catalytic function in addition to the adsorption and absorption of harmful substances from water and radiation for physical property change by utilizing the original functions and characteristics of the ore. You can make it possible. When the sintering process is changed in the hot air drying method for this, the production of functional tennis balls becomes possible.

This is because functional tennis balls are manufactured at a hot air drying temperature of 150°C to 170°C so that there is no loss in the characteristics and functions of the ore, rather than varying the sintering temperature of each raw material according to the type of ore. Can be completed widely.

Therefore, the present invention is characterized by adsorption, absorption, radiation, emission, catalyst, which is a unique function of natural ore to obtain a clean effect by manufacturing a function-oriented tennis ball by different molding and firing methods suitable for each ore's function and characteristics. There is an advantage of being able to manufacture a high-quality functional tennis ball having functions at the same time.

In addition, the present invention provides a functional tennis ball having durability that does not loosen or collapse even under the pressure and flow rate of water by connecting the particles and the particles in a hot air drying method of 150°C to 170°C. There is an advantage that can be manufactured.
