What exactly is Potassium Stearate ?

Potassium stearate can also be referred to in the form of "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in ether, chloroform and carbon disulfide. The solution that is aqueous is alkaline to litmus or phenolphthalein and the ethanol solution can be slightly acidic to phenolphthalein. It can be made by neutralizing the reaction of stearic acids with potassium hydroxide. It is widely used in the production from surfactants and fibre softeners. It can also be used in the creation of anti-slip materials, graphene -modified glues for anti-caking, anti-caking, and waterproof coils.

1 . This is used to create a novel type or non-slip substance

The new non-slip materials has strong wear resistance and anti-slip performance, and the raw materials in the formula are naturally available to purchase. The manufacturing process is the process is easy and user-friendly, and the manufacturer offers a large and convenient material formula. Materials used in production include brief fiber, water-based glu zinc oxide, anti-aging agents, photoinitiator (stearic acid), Potassium Stearate, potassium stearate also known as coupling agent. Carbon fiber. These are calculated in accordance with the mass percent, this new non-slip material includes 5-10 pieces of very short fibers 0.5-5 components of water-based glue. 3-7 bits zinc oxide 1-5 parts of antioxidant, 2-8 strips of stearic acid, 1-5 parts of photoinitiator Potassium stearate 10-13 parts, 1-8 parts of potassium-stearate 3-10 elements of coupling, and 0.5-10 components of carbon fibre.

2. . used to prepare graphene-modified glue

Graphene can be 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 follows:

Level 1, the graphene is added to n'butanol and toluene. Ultrasonic dispersion becomes 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 ceases, and the temperature is decreased to 80°C. adding ethylenediamine to the reaction, thoroughly stirred, and allowed to stand for a full day, resulting in one graphene-modified gluing.

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

To lessen the chance of having the risk of high blood pressure it is currently allowed to add some of potassium chloride as a replacement for sodium chloride within the edible salt. In the course of storage and transportation of potassium chloride, the moisture in the product can cause recrystallization and dissolution of the powder surface, thereby forming crystal bridges in its pores as well as the crystals get incorporated with one another over time to form. Huge mass. The weakening of fluidity impacts its use in table salt. To stop the formation of agglomeration it is essential to use a suitable amount of anticaking agent throughout the process of production.

The anti-caking compound used in food-grade potassium chloride is non-toxic, harmless in its color, odor, and colorlessness. It is composed of D-mannitol the potassium stearate compound, potassium, and calcium dihydrogen phosphate. the specific gravity of D-mannitol, potassium stearate, as well as dihydrogenphosphate are (1.25-5): (0.1-0.4) 1. The purity of the D-mannitol, potassium-stearate as well as calcium dihydrogen are food grade. In comparison to the prior art it has the advantages of being colourless or slightly white, does not alter the hue of the potassium chloride and is free of cyanide, is not toxic, and non-harmful.

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

Polyethylene polypropylene (PPE) is a relatively new material which has been in use for a while. Polypropylene is made of polypropylene non-woven fabric and polyethylene as the basic raw material. It is composed of anti-aging compounds and added by high-tech technology, and cutting-edge technology. The polymer polyethylene polypropylene waterproof roll material that has an integrated layer has significant friction coefficient, excellent quality, durability as well as a very low linear expansion coefficient, extensive temperature range of temperature adaptation, superb weather resistance, chemical resistance and elasticity. This makes it an ideal green protection for the environment in the 21st century. The method for making the waterproofing high-molecular polyethylene polypropylene membrane comprises the following steps:

Step 1: Measure the raw materials in accordance to the following parts by weight: 80-130 parts of polyethylene resin. 10-20 parts of the talcum powder, 5-10 portions of silica fume. Five to ten parts made of glass, as well as 8-16 parts of potassium stearate. 8-18 pieces, carboxylated, styrenebutadiene latex and 10-20 parts of anti-aging agents.

Step 2: Put silica fume, talcum powder as well as potassium stearate and carboxylated styrene-butadiene in a high-speed mixer. Turn up the temperature until 70-80 degrees C. Stir the mixture at high speed for around 8 to 18 minutes and then increase the temperature until it reaches 95-100 degrees C. Then, glass microbead and polyethylene resin are added to the mixture is stirred at a high speed for 10-20 mins in order to get a mixture

Step 3: Place the mixture into the feeding zone, extrude and form the sheets of polypropylene and plastic sheet completely with the 3-roller machine. Next, transfer the guide roller through the tractor, then cut the edges, then move into the coiler to obtain the finished product.

Compared with the previous art advantageous advantages of the invention include that it creates synergistic effects by an adsorbent polyethylene resin, silica-based fumes and glass microbeads, potassium stearate and carboxylated styrene butad in the form of anti-aging and latex and the subsequent steps to prepare, especially When the high-speed mixing procedure is used using a specific order for the input of the raw materials is very vital. In conjunction with the sequence of the invention the performance of the produced high-molecular Polyethylene polypropylene waterproofing membrane outperforms that of the more conventional membrane for waterproofing with high performance.
