Description

DETAILED DESCRIPTION OF THE INVENTION The present invention allows for any combination of various natural or man-made fibers, first rolled into a cloth with a thickness of about s mm, and then nylon,
It is immersed in a gel body made by mixing and stirring stone cotton powder, quartz powder, and dilute sulfuric acid, rolled into a flat plate with rollers, further submerged in water, rolled into a corrugated shape through a corrugated roller, and then deoxidized again.
After drying, it is immersed in waterproof asphalt containing an ultraviolet absorber, dried again, and then heated and rolled using corrugated rollers to create a finished product.

Most of the slates currently on the market are asbestos boards, and that's it. 1 piece, made of PVC and 1.1 lath visceral fibers. Asbestos board has the effect of heat insulation □Externally,
The disadvantage is that it is easily damaged, and galvanized plates absorb heat quickly and have high temperatures. Although PVC and glass fiber boards can be used to collect light, their disadvantages are that they cannot withstand use and cannot be insulated.

Until now, someone has researched and used man-made fibers, rolled it into a cloth, and applied temperature and pressure to make slate, and another person has used the rolled cloth to immerse it in a sulfuric acid solution containing nylon dissolved in it to remove it. After applying acid, dehydration, and drying, it is heated and compressed into slate. However, since rolled cloth becomes a lump after applying temperature and pressure, although this is possible in theory, there is a big difference in actual production. Also, the rolled cloth is made of nylon (
50% to 70%), volcanic clay (50% to 30%), and 2 to 4 times dilute sulfuric acid are added and stirred, then immersed in a gel body, deoxidized and dried, and then rolled into slate. In this manufacturing process, when a dried hardboard is heated and rolled, creases are likely to occur, and especially in volcanic clay containing fillers, creases are more likely to occur.

If you want to keep the surface of a 3'x6' board in perfect shape when the temperature is high enough to melt the nylon, you will never be able to do it unless you apply adhesive to the plastic. If the temperature is very low, the warpage that occurs will be more noticeable, and it is still good to make it into flat board interior decoration, but if it is made into slate, it has to be tested to withstand the climate, so there are many There are problems with this.

Although the inventor of the present invention repeatedly used hydraulic machines and rollers to test the problem many times, and even tested small areas, it was not possible to overcome the difficulties. The present invention addresses this test failure by introducing a protective film that forms when the nylon and filler come into contact with water, a gradual hardening process in water, and a corrugated roller in water before deoxidizing and dehydrating the nylon and filler. The results of research on rolling the material in water, first shaping it, cutting it into pieces, and then deoxidizing it again showed very good results. The underwater molding production method of the present invention can eliminate all the mistakes made up to this point, and I believe that general products cannot be molded until they are dry, so you must wait for them to dry, but especially with this product. First, deoxidation and dehydration are performed, and then heating and drying is started again, so this seven-ton facility is not a small one, and the construction work is quite large. The present invention rectifies this drawback, with a success rate of 1
00% and can be used for industrial production.

The present invention applies a process in which a protective film that is formed when a gel body made by adding sulfuric acid to nylon and a filler and stirring it comes into contact with water gradually hardens in water. It should be installed properly.

- In the second set, first roll the center wave, then in the second set, roll the two parts on the left and right sides of the center wave, and from the third set onwards, roll according to the order until all the corrugations are completed, and finally, once again, roll the two parts on the left and right sides of the center wave. Collect the waveforms of

The rolling time and the length of pulling in water are approximately 20m~
Install the above corrugated roller in a 30m long water tank,
The pulling speed shall be 0.3 to 0.6 m in 5 to 10 seconds. The present invention has thoroughly created a material that is weatherproof, heat resistant, fire resistant, impact resistant and impermeable to water, and the fillers are stone cotton powder (30% to 20%), quartz powder (20% to 10%), and nylon (50% to 50%). 70%) and add 2 to 3 times as much dilute sulfuric acid. Stone cotton powder is a heat-insulating and fire-resistant material, and quartz powder is a material used for heat-insulating and fire-proofing spacecraft.The compressed and shaped board is raised to the surface of the water, cut into pieces of about 2 meters, and light sodium oxide is used. Or, after neutralizing with sodium carbonate, expose to moonlight, compensate for cloudy weather with a drying box, dry by exposing to moonlight for a few hours, then immerse again in waterproof asphalt with 5% UV absorber added. Then, after further drying, it is rolled using a corrugated face roller at a temperature of 100 to ISO degrees, and after being shaped in this way, a finished product is completed.

The explanation will be as follows with reference to the drawings.

The rolled clothing starts gluing at point 1, and then goes to the tongue at point 2 □
Nylon, quartz powder, etc. are placed in the middle of the process and mixed to form a gel, which is pasted at a speed of 1/15 m/sec, passed through a filtered water tank, and first made the first wave with the center roller of No. 4. Extrude, then push both the left and right waves, push out in order until eight waves are reached, and as soon as it reaches 5, the molding is completed underwater,
After passing through the cutting machine No. 6 and cutting it into pieces, and deoxidizing and drying, the shaping process begins at No. 7. In addition to the roller No. 8, the temperature is maintained at 220 degrees by automatic control, and four sets of rollers are used to keep the temperature at 220 degrees. If it reaches 9 after rolling, 1q shaping is completed,
The sliding board □10 that slipped down has now become a completed product.

In summary, the present invention has the following features.

12. When using materials, it is possible to use waste fibers, which are inexpensive and can also help eliminate pollution in society.

2. In manufacturing the equipment, the equipment is simple, and the forming process uses only two roller equipment, rolling the flat surface and rolling the corrugated shape, and adding a drying box and deoxidizing tank separately, following the economic principle. Matching.

3. During the manufacturing process, the nylon gel body comes into contact with water,
Applying the process of forming a protective film and gradually hardening, it is rolled in water to form a corrugated shape, making the corrugated formation firm and easy to deoxidize and dry after hardening. And fast.

4. In terms of quality, it can withstand heavy pressure, is resistant to aging, and has the effect of heat insulation and soundproofing.
