What exactly is Potassium Stearate ?

Potassium Stearate is also referred to for its alias "potassium octadecanoate". White powder with crystalline structure. Soluble in hot water, insoluble in chloroform, ether or carbon disulfide. The aqueous solution is strongly alkaline in comparison to phenolphthalein or litmus and the ethanol mixture somewhat alkaline to the phenolphthalein. It is produced by neutralizing the reaction of stearic acid by potassium hydroxide. It is widely used in the production in the production of surfactants, fiber softeners and so on. It is also used in the creation of anti-slip substances, graphene-modified glues also known as anti-caking substances, as well as waterproof coils.

1 . The 1 is used to design a different kind made of material with no slip

The new non-slip surface has strong wear resistance and anti-slip performance, and the raw materials used in the formula is natural to purchase. When it comes to manufacturing, the method is simple and easy to follow, and the manufacturer uses an extensive and efficient formula. The production materials are: shorter fibers, glue based on water zinc oxide(zinc oxide), anti-aging substance, photoinitiator and stearic acid. Potassium thermo-sulfate, potassium in combination with coupling agent and carbon fiber. Based on the percentage of mass. This novel non-slip product includes 5-10 parts of fiber, 0.5-5 part of water-based glue. Three to seven pieces zinc oxide, 1-5 antioxidant pieces two to eight slices of stearic acids 1-5 pieces of photoinitiator Potassium Stearate 10-13 parts 1-8 parts of potassium-stearate 3-10 elements of coupling, along with 0.5-10 portions of carbon.

2. . used to prepare graphene-modified glue

Graphene is added to the existing glue to alter the high-temperature resistant of the 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 these:

Level 1: The graphene is mixed with n-butanol and toluene. The ultrasonic dispersion is uniform, to create 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 reduced to 80 degrees C. adding ethylenediamine to the reactor, stirred uniformly for a few minutes, then allowed to sit for a day to yield an unmodified graphene glue.

3. Preparation and formulation of composite anti-caking agents to be used in potassium chloride that is food grade

In order to reduce the possibility of high blood pressure, it's now permissible to add a fraction of potassium chloride to replace sodium chloride within the edible salt. In the course that involves the storage and transportation of potassium chloride, the moisture contained in the salt promotes recrystallization and dissolution of the powder's surface. It forms crystal bridges in the pores of the powder and crystals are then bonded with each other over time to form. Huge mass. The weakening of fluidity affects its use in table salt. Thus, to avoid agglomeration, it's important to add a sufficient amount of anticaking agent to the process of production.

The anticaking additive used in food-grade potassium chloride is safe, harmless colored, and odorless. It's composed of D-mannitol in combination with potassium stearate as well as calcium dihydrogenphosphate. the specific gravity of D'mannitol, potassium stearate, as well as dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of D-mannitolcompound, potassium stearate and calcium dihydrogen and phosphate is food grade. Compared with the prior art this invention offers the benefits of being colorless and slightly white, does NOT alter the color of potassium chloride, does not contain cyanide, is not toxic, and harmless.

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

Polyethylene Polypropylene, a new substance that has come into use in recent years. Polypropylene is made of polypropylene non-woven fabric and polyethylene, which is the raw material. It is composed of anti-aging substances and made by the latest high-tech technologyand modern technology. The polymer polyethylene polypropylene composite water-proof roll material that has an integrated coating has a huge friction coefficients, excellent quality, durability and a small linear expansion coefficient, a wide temperatures, good chemical resistance, weather resistance, and flexibility. This characteristic makes it an ideal green product for environmental protection in the 21st century. The preparation method of the high-molecular Polyethylene polypropylene waterproofing membrane involves the following steps:

Step 1: Measure the raw materials according to the following weights by weight in the range of 80-130 parts polyethylene resin. Also, 10-20 percent of talcum powder. 5-10 parts of silica-based fume, 5-10 bits of glass bead, and 8-16 pieces of potassium Stearate. 8-18 pieces of carboxylated butadiene latex, 10-20 percent of anti-aging agents;

Step 2: Place talcum powder, silica fume potassium stearate, carboxylated latex of styrene and butadiene into high-speed mixer. Raise the temperature to 70 to 80 deg C, then stir it at high speed for 8 to 18 minutes, and then raise the heat up to 95-100 deg Celsius. After that, a glass microbeads and polyethylene resin are added to the mixture is stirred with a high velocity for 10-20 minutes to create a mixture;

Step 3: Pour the mixture into the feeding area to extrude the sheets of polypropylene and plastic sheet entirely using the three-roller machine. Then, connect the guide roller through an tractor, cut off the edges, then move into the coiler to get the product.

Comparatively to the existing art positive effects of this invention include the synergistic effect produced by materials such as polyethylene resin, silica fume, glass microbeads potassium stearate and carboxylated styrene butad latex, anti-aging agent, and subsequent preparation steps. especially When the high-speed mixing occurs by a sequence of introducing the raw materials is especially vital. Together with the sequence of this invention in the present invention, the performance of developed high-molecularly polyethylene polypropylene waterproofing membrane can be superior the standard high-performance waterproofing membrane.
