What exactly is Potassium Stearate ?
Potassium-stearate is also referred in the form of "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution is alkaline with phenolphthalein and litmus The ethanol solution can be slightly acidic to phenolphthalein. It is produced by neutralizing the reaction of stearic acids with potassium hydroxide. It is commonly used in the production from surfactants and fibre softeners. It can also be utilized in the fabrication of anti-slip material, graphene modified glues as well as anti-caking agents and waterproof coils.

In the manufacturing process, the procedure is easy and simple to use, and the manufacturer provides an extensive and efficient formula. Production materials include: Short fiber, water-based glue, zinc oxide, anti-aging agent, photoinitiator (stearic acid), Potassium stearate, potassium the coupling agent as well as carbon fiber. These are calculated in accordance with the mass percent, this innovative non-slip material contains: 5-10 parts of shorter cords, 0.5-5 components of water-based glue. 3-7 bits of zinc oxide 1-5 pieces of antioxidant 2-8 slices , stearic acid 1-5 pieces of photoinitiator, Potassium stearate 10-13 parts, 1-8 parts potassium stearate 3-10 components of coupling, along with 0.5-10 components of carbon fibre.
2. . It is used to make a graphene-modified glue
Graphene can be added to the existing glue to alter the resistance to high temperature of the cement and improve its adhesion. The material for preparing the paste is calculated by parts by weight: 12-30 parts of polyurethane, 15-30 parts of chloroprene rubber, 15-30 parts of polyacrylate, 2-12 parts of graphene, triallyl isocyanuric acid 0.8-1.6 parts of ester, 1-6 pieces of ethylenediamine, 2-10 parts of n-butanol, 2-8 pieces of toluene, 0.8-3 parts of potassium stearate, 2-8 parts of polyvinylpyrrolidone, N- 1-5 parts of phenyl-b-naphthylamine;
The steps specific to HTML0 are as these:
Level 1: The graphene is added to n-butanol and toluene. Ultrasonic dispersion is uniform to produce a mixed solution;
Step 2, adding polyurethane, chloroprene rubber, and polyacrylate into the reactor, the temperature is raised to 80-105 deg C, the reaction is 1-3 hours, and then the mixed solution A and triallyl isocyanurate in the first step The acid ester, potassium stearate, polyvinylpyrrolidone, and N-phenyl-b-naphthylamine are sequentially added to the reactor, the reaction temperature is adjusted to 150-360 deg C, and the reaction is carried out for 2-5 hours to obtain a mixture B;
Step 3: Above reaction is stopped. the temperature decreases to 80 degrees C. and ethylenediamine added to the reaction, thoroughly stirred, and allowed to stand for a few days to create an unmodified graphene glue.
3. Preparation of a composite anticaking agent for use in food-grade potassium chloride
In order to lessen the risk of higher blood pressure it is permitted to now add a small amount of potassium chloride to substitute sodium chloride from the edible salt. However, in the process to store and transport potassium chloride, the moisture in the product facilitates the decomposition and recrystallization powder's surface. This results in a crystal bridge at the pores of the powder, and the crystals combine with each other over time to form. Huge mass. The weakening effect of fluidity affects the use of table salt. So, to stop agglomeration from occurring, it is important to add a sufficient amount of anti-caking agent during the production process.
The anti-caking compound used in food-grade potassium chloride is safe, harmless, colorless, and odorless. It is composed of D-mannitol along with potassium stearate and calcium dihydrogenphosphate. the specific gravity of D-mannitol, potassium stearate, and dihydrogenphosphate are (1.25-5): (0.1-0.4) 1. The purity of the D-mannitolcompound, potassium stearate and calcium dihydrogenphosphate is food grade. In comparison to the prior art this invention offers the advantages of colorless or slightly white, does not alter the whiteness of potassium chloride. is free of cyanideand is therefore non-toxic and safe.
4 . The production of high-molecular polyethylene polyester waterproof membrane
Polyethylene Polypropylene is a novel substance that has come into use in recent years. Polypropylene is made of polypropylene non-woven fabric as well as polyethylene as the basic raw material. It is made from anti-aging chemicals and processed using the most advanced, high-tech technology, and cutting-edge technology. The polymer polyethylene polypropylene waterproof roll material with an integrated layer features a significant friction coefficient, superb stability, high mechanical strength and a small linear expansion coefficient, large temperature range of temperature adaptation, superb chemical resistance, weather resistance and elasticity. This characteristic makes it an ideal green protection for the environment in the new century. The process of making the high-molecular polyethylene polypropylene waterproofing membrane comprises the following steps:
Step 1: Measure the raw materials in accordance to the following weights by weight: 80-130 parts of polyethylene resin. Also, 10-20 percent of clay powder, 5-10 components of silica fume. Five to ten parts that are glass beads. Also, 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated styrene butadiene latex and 10-20 parts of the anti-aging ingredient;
Step 2: Add talcum powder, silica fume potassium stearate, carboxylated styrene-butadiene latex into a high-speed mixer. Turn up the temperature to 70-80 deg C, and stir at a high speed for 8 to 18 min, and then raise the heat to 95 to 100 degrees Celsius. Following that, glass microbead and polyethylene resin are added and the mixture is stirred at a rapid speed for about 10 to 20 minutes until you get a perfect mixture.
Step 3: Insert the mixture in the feeding area create the extrusion and sheet of polypropylene as well as the plastic sheet completely with the 3-roller machine. Then, connect this guide roller over to the tractor, cut the edge, and enter an electric coiler to make the finished product.
Comparatively to the previously known techniques, the advantageous outcomes of the invention are the synergistic effect produced by an adsorbent polyethylene resin silica fumes, glass microbeads, potassium stearate and carboxylated styrene butad anti-aging agent, latex and any subsequent preparation steps, particularly when the high-speed mixing process is being carried out using a specific order for the input of the raw materials is especially crucial. Together with the sequence of the present invention, the performance of the created high-molecular polyethylene and polypropylene waterproofing membrane can be superior that of the typical high-performance waterproofing membrane.
