What is Potassium stearate

What is Potassium stearate ?

Potassium Stearate is also referred to by the name of "potassium octadecanoate". White crystalline powder. It is soluble in hot water and insoluble in ether, chloroform or carbon disulfide. The aqueous solution is alkaline to litmus or phenolphthalein and the ethanol solution will be slightly alkaline to that of phenolphthalein. It can be obtained by neutralizing the reaction of stearic acids with potassium hydroxide. Commonly used in the manufacture for surfactants as well as fiber softeners. It can also be utilized in the fabrication of anti-slip materials, graphene -modified glues anti-caking agents, as well as waterproof coils.

1 . utilized to prepare a completely new type or non-slip substance

The non-slip new material comes with robust wear resistance and anti-slip performance, and the raw materials used in the formula is natural to purchase. For the production process, the method is simple and straightforward to use, and the manufacturer uses a large and convenient material formula. Materials used in production include brief fiber, water-based glu, Zinc Oxide, Anti-Aging agent, photoinitiator (stearic acid), Potassium stearate, potassium stearate or coupling agent, and carbon fiber. The fiber is calculated based on its mass percentage. new non-slip material Including 5-10 parts of long cord, 0.5-5 parts of water-based glue, 3-7 pieces zinc oxide, one to five pieces of antioxidant 2-8 slices of stearic acids, 1-5 parts of photoinitiator, Potassium stearate 10-13 parts, 1-8 pieces of potassium stearate three to ten parts of coupling agents plus 0.5-10 pieces of carbon fiber.

2 . used to prepare a graphene-modified glue

Graphene can be added to the existing glue to modify its resistance to high temperatures 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 steps specific to HTML0 are as the following:

Level 1, the graphene is mixed with n-butanol and toluene. The ultrasonic dispersion is uniform. make a mixed mixture 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 above reaction ceases, and it is then lowered to 80°C. ethylenediamine is added to the reactor, stirred uniformly, and allowed to stand for a day in order to produce the graphene modified glue.

3. Preparation of a composite anti-caking agent to be used in potassium chloride that is food grade

To lower the risk of excessive blood pressure it is now allowed to add part of potassium chloride that replaces sodium chloride that is present in the salt. In the course of transportation and storage of potassium chloride contained in the salt promotes decomposition and recrystallization powder's surface. This creates an elongated crystal structure in the pores of the powder and the crystals are combined to form a crystal bridge over time. to form. Huge mass. The weakening in fluidity can affect its usage in table salt. Therefore, in order to prevent agglomeration, its imperative to add the right amount of anticaking agent to 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 made up of D-mannitol, potassium stearate, as well as calcium dihydrogen phosphate, wherein the specific gravity of D-mannitol, potassium stearate, and dihydrogenphosphate are (1.25-5): (0.1-0.4): 1. The purity of the D-mannitol, potassium Stearate, and calcium dihydrogenphosphate is food grade. In comparison to other known methods the invention has advantages of being colourless or slightly white, does not change the appearance of the color of potassium chloride. It is free of cyanide, is non-toxic, and harmless.

4 . The production of high-molecular-polyethylene polyester waterproof membrane

Polyethylene Polypropylene, a new material that has recently been utilized. Polypropylene is made up of non-woven polypropylene fabric and polyethylene as the primary raw material. It is made of anti-aging agents and is added by high-tech technologies and advanced technology. The polymer polyethylene polypropylene composite waterproof roll material that has an integrated layer is characterized by a high friction coefficient, exceptional stability, high mechanical strength, small linear expansion coefficients, a large temperatures, good weather resistance, chemical resistance and elasticity. This makes it an ideal green protection for the environment in the 21st century. The process for making the high-molecular polyethylene polypropylene waterproofing membrane includes the following steps:

Step 1: Weigh the raw materials according to the following parts of weight (80-130 parts of polyethylene resin, 10-20 pieces of talcum powder. Five to 10 parts of silica fume, 5-10 pieces of glass bead, and 8-16 parts of potassium Stearate. 8-18 pieces carboxylated latex, 10-20 percent of anti-aging agents.

Step 2: Mix talcum powder, silica fume in combination with potassium stearate and carboxylated styrene butadiene latex in a high-speed mixer, raise the temperature until 70-80 degrees C, and stir at a high speed for about 8 to 18 mins, and then increase the heat until it reaches 95-100 degrees C. Then, polyethylene resin and glass microbeads are added to the mixture is stirred on high velocity for 10-20 minutes until you get a perfect mixture.

Step 3: Pour the mix into the feeding space create the extrusion and sheets of polypropylene and plastic sheet in the complete manner using the three roller machine. Transfer one of the guide rollers to the tractor, trim the edges, then move into it into the coiler, forming the product.

In comparison to the prior art, the advantageous effects of this invention include synergistic results from Polyethylene Resin, Talc, silica , glass microbeads potassium stearate, carboxylated styrene-butadiene latex, anti-aging agent, and further preparation steps, particularly when the high-speed mixing is performed with the proper order of input of the raw materials can be vital. In combination with the sequence of this invention it is evident that the performance of the constructed high-molecular-molecular-molecular-polypropy membrane far exceeds the high-performance membranes for waterproofing.
