What is Potassium stearate

What's Potassium Stearate ?

Potassium stearate may also be referred for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in chloroform, ether as well as carbon disulfide. The aqueous solution is strongly alkaline in comparison to phenolphthalein or litmus and the ethanol solutions has a slight alkaline form to phenolphthalein. It can be made by neutralizing the reactions of stearic and potassium hydroxide. It is frequently used in the making for surfactants as well as fiber softeners. It is also used to create anti-slip material, graphene modified glues for anti-caking, anti-caking, and waterproof coils.

1. . utilized to prepare a completely new type of non-slip material

The latest non-slip fabric has great wear resistance and antislip performance. Additionally, the raw ingredients in the formula are readily available for purchase. The manufacturing process is the process is easy and user-friendly, and the manufacturer provides an extensive and efficient material formula. Production materials include: brief fiber, water-based glu, zinc oxideand anti-aging agents, photoinitiator, stearic acid Potassium stearate, potassium stearate or coupling agent, and carbon fiber, calculated according to the mass percentage. This new non-slip material includes 5-10 parts of the length cord 0.5-5 components of water-based glue. 3-7 bits of zinc oxide, 1-5 parts of antioxidant 2-8 slices of stearic acid 1-5 pieces of photoinitiator Potassium Stearate 10-13 Parts, 1-8 parts in potassium stearate 3-10 components of coupling and 0.5-10 pieces of carbon fiber.

2 . utilized to make graphene-modified glue

Graphene is included in the existing glue to modify its high-temperature resistance cement and increase 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 below:

Level 1, the graphene is added to n'butanol and toluene. Ultrasonic dispersion of the mixture is uniform to get 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, and the temperature drops to around 80 degrees Celsius. ethylenediamine gets added to the reactor, stirred uniformly and then left to stand for one day before obtaining the graphene-modified glue.

3. Preparation of composite anti-caking agent for use in potassium chloride that is food grade

In order to reduce the possibility of higher blood pressure it is now permissible to add a fraction of potassium chloride to replace sodium chloride that is present in the salt. But, during the process transport and storage of potassium chloride contained in the salt promotes breakdown and recrystallization on the porous surface of the powder, resulting in an intergranular bridge in these pores, and then the crystals join together over time to develop. Huge mass. The weakening of fluidity influences the use of table salt. To prevent agglomeration, its vital to include a proper amount of anticaking agent throughout the production process.

The anti-caking compound used in food-grade potassium chloride is non-toxic harmless and colorless. It also has no odor. It's made up of D mannitol as well as potassium stearate and calcium dihydrogenphosphate. the specific gravity of D-mannitol potassium stearate and dihydrogen phosphate is (1.25-5): (0.1-0.4) 1. The purity of D-mannitol, potassium Stearate, and calcium dihydrogen and phosphate is food grade. Compared with the prior art, the invention has the advantages of being colourless or slightly white, and does not alter the colour of potassium chloride. It also does not contain cyanide, is non-toxic, and harmless.

4 . The production of high-molecularly polyethylene the waterproof membrane is made of polypropylene

Polyethylene Polypropylene is an innovative substance that has come into use in recent years. Polypropylene is composed of polypropylene non-woven fabrics and polyethylene as the main raw material. It is made with anti-aging components and added by high-tech technologyand modern technology. The Polymer Polyethylene Polypropylene Composite waterproof roll material that has an integrated layer offers a large friction coefficient, great durability, stability, high mechanical strength as well as a very low linear expansion coefficient, wide temperature adaptability, great chemical resistance, weather resistance and elasticity. This characteristic makes it an ideal environmentally friendly product for the current century. The preparation method of the high-molecular-molecular-molecular-polyethylene waterproof membrane comprises the following steps:

Step 1: Measure the raw materials according to the following weights by weight (80-130 parts of polyethylene resin. Also, 10-20 percent of Talcum powder, 5-10 pieces of silica gas, 5-10 portions made of glass, as well as 8-16 parts of potassium Stearate. 8-18 pieces, carboxylated, styrenebutadiene latex, 10-20 percent of the anti-aging substance;

Step 2: Add talcum powder, silica fume, potassium stearate and carboxylated styrenebutadiene latex into high-speed mixer. Increase the temperature until 70-80 degrees C, mix at a high speed for between 8 and 18 minutes, and then increase the heat by 95-100 degrees Celsius. Following that, polyethylene resin and glass microbeads are added and the mixture is stirred at a rapid speed for 10 to 20 mins to make a blend;

Step 3: Add the mixture in the feeding area to extrude the Polypropylene sheet, as well as the plastic sheet entirely using the three-roller machine. Transfer this guide roller over to it, cut the edge, and enter the coiler to get the finished product.

Comparing to earlier art positive effects of this invention include an effect of synergy between the polyethylene resin silica fumes, glass microbeads potassium stearate, carboxylated butadiene in the form of anti-aging and latex and subsequent preparation processes, especially When the high-speed mixing process is being carried out at a particular order, the method of introducing the raw materials is particularly crucial. In conjunction with the sequence of the present invention the performance of the made high-molecular polyethylene polypropylene waterproofing membrane outperforms the traditional high-performance waterproofing membrane.
