What's Potassium stearate ?

Potassium stearate can also be referred to by the name of "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in ether, chloroform as well as carbon disulfide. The aqueous solution tends to be alkaline in comparison to phenolphthalein or litmus and the ethanol mixture may be slightly alkaline in comparison to phenolphthalein. It is obtained by neutralizing the reactions of stearic and potassium hydroxide. Commonly , it is used in the manufacturing of fiber softeners and surfactants. It can also be utilized in the fabrication of anti-slip products, graphene-modified adhesives also known as anti-caking substances, as well as waterproof coils.

1. . Used to make a new kind of slip-resistant material

The new non-slip material has an excellent wear resistance and anti-slip performance. The raw materials used in the formula is organic and easy to obtain. In the manufacturing process, the method is simple and straightforward to use, and the manufacturer provides an extensive and easy-to-use material formula. Production materials include: the short-fiber, water-based adhesive, Zinc Oxide, Anti-Aging substance, photoinitiator and stearic acid. Potassium thermo-sulfate, potassium in combination with coupling agent and carbon fiber. The fiber is calculated based on the percentage of mass. This new non-slip material Including 5-10 parts of long cord, 0.5-5 portions of glue based on water, 3-7 parts zinc oxide 5 pieces of antioxidant 2-8 slices , stearic acids 1-5 pieces of photoinitiator, Potassium Stearate 10-13 Parts, 1-8 pieces of potassium stearate 3-10 components of coupling, along with 0.5-10 pieces of carbon fiber.

2. . utilized to make graphene-modified glue

The addition of graphene to the existing glue to alter the high-temperature resistance 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 gets added to n'butanol and toluene, the ultrasonic dispersion 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 ceases, and the temperature decreases to around 80 degrees Celsius. in the step 3, ethylenediamine enters the reactor, which is stirred continuously and left to stand for one day to obtain the graphene-modified glue.

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

To lessen the risk of increased blood pressure it is currently allowed to add some of potassium chloride to replace sodium chloride present in the salt. In the course that involves the storage and transportation of potassium chloride in the product can cause recrystallization and dissolution of material's surface, creating a crystal bridge at the pores of the powder and the crystals are merged with each other over time to form. Huge mass. The weakening of fluidity influences its use in table salt. So, to stop the formation of agglomeration it is required to add an appropriate quantity of anti-caking agents during the process of production.

The anti-caking compound used in food-grade potassium chloride is non-toxic, harmless colored, and odorless. It is composed of D-mannitol along with potassium stearate and calcium dihydrogen phosphate. the specific gravity of D'mannitol potassium stearate, and dihydrogen phosphate are (1.25-5): (0.1-0.4): 1. The purity of the D-mannitol, potassium-stearate and calcium dihydrogen is food grade. As compared to prior art, the invention has the advantages of being completely colorless or white, it does not alter the colour of potassium chloride. It also does not contain cyanide, and is non-toxic and is safe.

4 . The process of making high-molecular polyethylene the waterproof membrane is made of polypropylene

Polyethylene polypropylene has become a revolutionary material that has been used in the last few years. Polypropylene is a blend of polypropylene fabric that is non-woven and polyethylene for the primary raw material. It is composed with anti-aging components and blended with high-tech technologyand innovative technology. The polyester polypropylene water-proof roll material that has an integrated layer has a substantial friction coefficient, great durability, stability, high mechanical strength as well as a very low linear expansion coefficient, a wide temperature adaptability range, exceptional chemical resistance, weather resistance, and flexibility. The characteristic is an ideal environmentally-friendly protection product for the new century. The procedure of making the high-molecular ethylene polypropylene waterproofing membrane consists of the following steps:

Step 1: Measure the raw materials in accordance with the following percentages by weight in the range of 80-130 parts polyethylene resin. 10-20 parts of Talcum powder, 5-10 pieces of silica fume, 5-10 parts of glass beads, and 8-16 pieces of potassium stearate. 8-18 pieces carboxylated latex, 10-20 components of the anti-aging agent;

Step 2: Place silica fume, talcum powder, potassium stearate and carboxylated styrene-butadiene latex into a high-speed mixer. Adjust the temperature to 70 to 80 deg C. Stir the mixture at high speed for between 8 and 18 minutes, and then increase the temperature to 95-100 degrees Celsius. After that, a glass microbeads and polyethylene resin are added and the mixture is stirred up at a high speed for about 10 to 20 minutes to obtain a combination;

Step 3 : Put the mixture into the feeding zone, extrude and form the sheet of polypropylene, and then the plastic sheet completely by the three-roller machine. After that, you can pass one of the guide rollers to the tractor, cut the edges, and then enter an electric coiler to make the final product.

Comparing to prior art, the advantageous benefits of this invention are: synergistic effect by Polyethylene Resin, Talc silica-based fumes and glass microbeads potassium stearate in the form of anti-aging and latex and any subsequent preparation steps, especially when high-speed mixing occurs, the order of inputting the raw materials is especially significant. Together with the sequence of the present invention in the present invention, the performance of created high-molecular polyethylene and polypropylene waterproofing membrane outperforms traditional waterproofing membranes that are high-performance.
