What is Potassium stearate

What exactly is Potassium stearate ?

Potassium stearate can also be referred to in the form of "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution appears to be alkaline with phenolphthalein and litmus, and the ethanol solution is slightly alkaline to phenolphthalein. It is made by neutralizing the reactions of stearic and potassium hydroxide. Commonly used in the manufacture of softeners for fibers and other surfactants. It can also be used to create anti-slip material, graphene modified glues Anti-caking agents, waterproof coils.

1. . The 1 is used to design a different kind in non-slip fabric

The new non-slip materials has great wear resistance and antislip ability, and the materials that make up the formula are simple to buy. In the process of making it, the method is simple and straightforward to use, and the manufacturer uses a vast and user-friendly material formula. Production materials include: brief fiber, water-based glu, the zinc oxide compound, an anti-aging agents, stearic acid, photoinitiator, Potassium thermo-sulfate, potassium stearate also known as coupling agent. Carbon fiber. All of these are calculated according to the mass percentage. new non-slip materials includes: 5-10 parts of length cord 0.5-5 percent of water-based glue. zinc oxide one to five pieces of antioxidant, 2-8 slices of acids 1-5 components of photoinitiator, Potassium Stearate 10-13 parts 1-8 pieces of potassium stearate 3-10 components of coupling as well as 0.5-10 components of carbon fibre.

2. . Used to prepare graphene-modified glue

The addition of graphene to the existing glue to modify the resistance to high temperature of the cement and to 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 specific steps are as like:

Level 1: The graphene component is added to nbutanol and toluene, ultrasonic dispersion is uniform, in order to achieve a mixed solutions A;

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: The previous reaction is stopped. the temperature is decreased to around 80 degrees Celsius. an ethylenediamine solution is added to reactor, stirred uniformly and left to stand for a day in order to produce a graphene-modified glue.

3. The preparation of composite anticaking agent to be used in potassium chloride that is food grade

To minimize the possibility of excessive blood pressure it's now permitted to add a portion of potassium chloride , which replaces sodium chloride from the edible salt. In the course of transportation and storage for potassium chloride, the moisture contained in the product can cause melting and recrystallization powder's surface. This creates crystal bridges within each of the powder's pores, and the crystals are merged with each other over time to form. Huge mass. The weakening of fluidity influences its use in table salt. To prevent agglomeration, it is required to add an appropriate amount of anti-caking agent during the process of production.

The anti-caking compound used in food-grade potassium chloride is non-toxic, harmless as well as colorless and odorless. It's made of D-mannitol also known as potassium stearate. It is calcium dihydrogenphosphate. the specific gravity of D'mannitol potassium stearate, and dihydrogen phosphate are (1.25-5): (0.1-0.4): 1. The purity of D-mannitol, potassium-stearate as well as calcium dihydrogen are food grade. Contrary to prior technology the invention has advantages of colorless or slightly white, does not change the whiteness of potassium chloride, does not contain cyanide, and is non-toxic and safe.

4 . The production of high-molecular polyethylene waterproof membrane made from polypropylene

Polyethylene polypropylene is a brand new material used in recent years. Polypropylene is made up of polypropylene non-woven fabric and polyethylene as the main raw material. It is made with anti-aging components and blended with high-tech technology, and new technology. The polyester polypropylene water-proof roll material with an integrated layer has a substantial friction coefficients, high durability, stability, high mechanical strength, small linear expansion coefficient, a wide temperature adaptability range, exceptional chemical resistance, weather resistance and elasticity. It is a great sustainable product for protecting the environment in the current century. The procedure for the preparation of the high-molecular polyethylene polypropylene waterproofing membrane comprises the following steps:

Step 1: Measure the raw materials according to the following weight percentages: 80-130 parts of polyethylene resin, 10-20 parts of the talcum powder, 5-10 portions of silica fume. Five to ten parts of glass beads and 8-16 parts of potassium stearate. 8-18 pieces of carboxylated styrene butadiene latex; 10-20 parts of anti-aging agents;

Step 2: Place silica fume, talcum powder as well as potassium stearate and carboxylated styrene butadiene latex in a high-speed mixer. Adjust the temperature to 70-80 degrees C, then stir it at high speed for around 8 to 18 minutes and then increase the heat to 95 to 100 degrees Celsius. After that, a polyethylene resin and glass microbeads are added and the mixture is stirred with a high speed for about 10 to 20 minutes in order to get a mixture

Step 3: Place the mixture in the feeding area in order to extrude and create the sheet of polypropylene and the plastic sheet completely using the three-roller machine. Then, connect one of the guide rollers to the tractor, then cut the edges, then enter it into the coiler, forming the final product.

Comparatively to the prior art, the advantageous results of the invention comprise Synergistic effect from plastic resins, such as talc silica , glass microbeads potassium stearate, carboxylated butadiene anti-aging agent, latex and further preparation steps, especially when high-speed mixing occurs, the order of inputting the raw materials is extremely important. In conjunction with the sequence used in the present invention The performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane exceeds that of the traditional high-performance waterproofing membrane.
