What is Potassium stearate

What is Potassium Stearate ?

Potassium stearate can also be referred to in the form of "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in chloroform, ether and carbon disulfide. The aqueous solution is alkaline to litmus or phenolphthalein The ethanol solution will be slightly alkaline to that of phenolphthalein. It is made by neutralizing the reaction of stearic acid by potassium hydroxide. Commonly , it is used in the manufacturing for surfactants as well as fiber softeners. It is also used to create anti-slip products, graphene-modified adhesives for anti-caking, anti-caking, and waterproof coils.

1. . This is used to create a novel kind that is non-slip.

The new non-slip surface has strong wear resistance and anti-slip capability, and the raw components in the formula are organic and easy to obtain. When it comes to manufacturing, the procedure is easy and quick to perform, and the manufacturer provides the largest and most convenient formula. Materials used in production include small fiber, short fibre, water-based glue zinc oxideand anti-aging agents, photoinitiator, stearic acid Potassium thermo-stearate, potassium stearate, coupling agent and carbon fiber, calculated according to the mass percentage. new non-slip material Including 5-10 parts of fiber, 0.5-5 part of water-based glue. Three to seven pieces zinc oxide, one to five pieces of antioxidant 2-8 slices of acids 1-5 parts of photoinitiator, Potassium stearate 10-13 parts, 1-8 parts in potassium stearate 3-10 pieces of coupling agent in addition to 0.5-10 portions of carbon.

2 . Used to prepare graphene-modified glue

Graphene is incorporated into the existing glue to modify the high-temperature resistance of cement as well as 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 they are:

Level 1, the graphene is added to n-butanol and toluene. The ultrasonic dispersion remains 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;

3. Step 3, the previous reaction is stopped, and the temperature is decreased to around 80 degrees Celsius. in the step 3, ethylenediamine enters the reactor, and stirred evenly and then left to stand for a full day, resulting in an unmodified graphene glue.

3. Preparation of anti-caking composites to be used in potassium chloride food grade

To lessen the risk of higher blood pressure it's now possible to add a bit of potassium chloride to replace sodium chloride present in the salt. In the process in the storage and transport of potassium chloride in the product encourages melting and recrystallization material's surface, creating a crystal bridge at those pores in the powder, as well as the crystals get incorporated together over time to develop. Huge mass. Fluidity is weakened, which affects the use of table salt. In order to prevent agglomeration, its vital to include a proper amount of anticaking agent during the process of production.

The composite anti-caking agent used in food-grade potassium chloride is non-toxic harmless and colorless. It also has no odor. It is composed of D-mannitol also known as potassium stearate. It is calcium dihydrogen phosphate, wherein the specific gravity of D'mannitol potassium stearate, as well as dihydrogen phosphate are (1.25-5): (0.1-0.4) 1. The purity of the D-mannitolcompound, potassium stearate as well as calcium dihydrogen are food grade. When compared with prior art this invention has the benefits of being colorless, or somewhat white, does not alter the hue of the potassium chloride and is free of the cyanide element, is non-toxic and is safe.

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

Polyethylene polypropylene (PPE) is a relatively new material used in recent years. Polypropylene is made of polypropylene non-woven fabric as well as polyethylene as the primary raw material. It is composed of anti-aging substances and created by high-tech, modern technology, and cutting-edge technology. The polymer polyethylene polypropylene waterproof roll material that has an integrated layer boasts a significant friction coefficient, excellent stability, high mechanical strength Small linear expansion coefficient, broad temperatures, good weather resistance, chemical resistance and flexibility. This makes it an ideal green environmental protection product in the new century. The procedure of making the waterproofing membrane includes the following steps:

Step 1: Weigh the raw materials according to the following weight percentages that is 80-130 parts of polyethylene resin. Also, 10-20 percent of talcum powder. Five to 10 parts of silica fume, 5-10 parts that are glass beads. Also, 8-16 pieces of potassium stearate. 8-18 pieces of carboxylated latex, 10-20 pieces of the anti-aging agent

Step 2: Mix silica fume, talcum powder as well as potassium stearate and carboxylated styrene butadiene latex in a high-speed mixer. Raise the temperature until 70-80 degrees C. Mix at a fast rate for between 8 and 18 min, and then increase the temperature to 95 to 100 degrees Celsius. Then, glass microbead and polyethylene resin are added to the mixture is stirred at a rapid speed for 10-20 mins for a mix;

Step 3: Pour the mixture in the feeding area in order to extrude and create the polypropylene sheet as well as the poly sheet completely by the three-roller machine. After that, you can pass the guide roller onto the tractor, trim the edges and then insert the coiler to create the product.

As compared to the conventional methods, beneficial effects of this invention include an effect of synergy between an adsorbent polyethylene resin, silica fumes, glass microbeads potassium stearate, carboxylated butadiene an anti-aging chemical, and the subsequent steps to prepare, especially When the high-speed mixing is carried out with the proper order of input of the raw materials is especially important. When combined with the sequence of this invention the performance of the manufactured high-molecular ethylene polypropylene waterproofing membrane is superior to that of the high-performance membranes for waterproofing.
