What is Potassium stearate
What is Potassium stearate ?
Potassium-stearate is also referred in the form of "potassium octadecanoate". White crystalline powder. Soluble in hot water, insoluble in chloroform, ether and carbon disulfide. The aqueous solution tends to be alkaline to phenolphthalein or litmus and the ethanol solution has a slight alkaline form to phenolphthalein. It can be obtained by neutralizing the reactions of stearic and potassium hydroxide. Commonly utilized in the fabrication of fiber softeners and surfactants. It can also be utilized to make anti-slip substances, graphene-modified glues as well as anti-caking agents and waterproof coils.

2. . used to prepare graphene-modified glue
Graphene is added to existing glue to modify the high-temperature resistance of the cement and enhance 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 component is added to nbutanol and toluene, ultrasonic dispersion is uniform, in order 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;
Step 3: Above reaction is stopped, and the temperature drops to 80°C. and ethylenediamine added to the reactor, and stirred evenly for a few minutes, then allowed to sit for a whole day to make the graphene modified glue.
3. Preparation of a composite anti-caking agent for use in potassium chloride that is food grade
To reduce the possibility of excessive blood pressure it is now permissible to add a fraction from potassium chloride to replace sodium chloride within the edible salt. However, in the process of transportation and storage of potassium chloride, the moisture contained in the product causes breakdown and recrystallization on the powder's surface. It forms crystal bridges at each of the powder's pores and crystals are then bonded together over time to develop. Huge mass. The weakness of fluidity affects its use in table salt. To keep agglomeration at bay, it is important to add a sufficient quantity of anti-caking agents during the process of production.
The anticaking agent composite used in food-grade potassium chloride is safe, harmless that is colorless, odorless, and colorless. It is made up of D-mannitol also known as potassium stearate. It is calcium dihydrogen phosphate. the specific gravity of D-mannitol potassium stearate and dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of D-mannitoland potassium stearate and calcium dihydrogen is food grade. Compared with the prior art it has the benefits of being colorless and slightly white, does not change the whiteness of potassium chloride, does not contain cyanide, is not toxic, and non-harmful.
4. . The process of preparing high-molecular Polyethylene polypropylene waterproof membrane
Polyethylene Polypropylene is an innovative material in recent times. Polypropylene is a blend of polypropylene non-woven fabrics and polyethylene as its primary raw material. It is composed of anti-aging ingredients and manufactured using high-tech, advanced technology, and new technology. The polymer polyethylene and polypropylene composite waterproof roll material that has an integrated layer has significant friction coefficient, exceptional quality, durability Small linear expansion coefficientand a broad temperature range of adaptation, outstanding chemical resistance, weather resistance, and flexibility. This characteristic makes it an ideal sustainable product for protecting the environment in the new century. The preparation method of the high-molecular-molecular-molecular-polyethylene waterproof membrane includes the following steps:
Step 1: Weigh the raw materials according to the following percentages by weight in the range of 80-130 parts polyethylene resin. 10-20 parts of clay powder, 5-10 components of silica fume, 5-10 parts in glass beads. There are 8-16 parts of potassium stearate. 8-18 pieces of carboxylated latex, 10-20 pieces of the anti-aging ingredient;
Step 2: Pour silica fume, talcum powder potassium stearate, carboxylated styrene-butadiene latex into a high-speed mixer, raise the temperature until 70-80 degrees C, stir at high speed for about 8 to 18 mins, and then increase the heat up to 95-100 deg Celsius. After that, a polyethylene resin and glass microbeads are added to the mixture is stirred with a high speed for 10 to 20 mins to create a mixture;
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. Then, connect the guide roller through your tractor, then cut the edgeand then go into in the coiler machine to produce the product.
As compared to the earlier art advantageous advantages of the invention include: synergistic effect by materials such as polyethylene resin silica fumes, potassium stearate, carboxylated styrene-butadiene latex, anti-aging ingredient, and subsequent preparation steps, particularly when the high-speed mixing occurs with the proper order of input of ingredients is particularly significant. When combined with the sequence of the invention, the performance of the produced high-molecular Polyethylene polypropylene waterproofing membrane outperforms that of the high-performance membranes for waterproofing.
