What exactly is Potassium stearate ?
Potassium stearate is also known by the name of "potassium octadecanoate". White powder with crystalline structure. It is soluble in hot water and insoluble in chloroform, ether as well as carbon disulfide. The aqueous solution tends to be alkaline to litmus or phenolphthalein and the ethanol solutions can be slightly acidic to phenolphthalein. It is made by neutralizing the reaction of stearic acid with potassium hydroxide. Commonly used in the manufacture of softeners for fibers and other surfactants. It can also be used in the production of anti-slip products, graphene-modified adhesives anti-caking agents, as well as waterproof coils.
1. . used to develop a new type of non-slip material
The new non-slip materials has great wear resistance and antislip capability, and the raw ingredients in the formula are simple to buy. For the production process, the process is easy and user-friendly, and the company has an extensive and practical material formula. Materials used in production include Short fiber, water-based glue the zinc oxide compound, an anti-aging agent, photoinitiator (stearic acid), Potassium thermo-stearate, potassium stearate as well as coupling agent and carbon fiber. These are calculated in accordance with the mass percentage, this innovative non-slip material contains 5-10 pieces of short cord, 0.5-5 elements of water-based adhesive, 3-7 pieces zinc oxide 1-5 antioxidant pieces 2-8 slices , stearic acid, 1-5 parts of photoinitiator Potassium stearate 10-13 parts, 1-8 pieces of potassium stearate 3-10 pieces of coupling agent along with 0.5-10 parts of carbon fiber.
2. . utilized to make graphene-modified glue
Graphene adds to the existing glue to alter its resistance to high temperatures 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 the following:
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: The above reaction is stopped, and the temperature is brought down to 80 deg C, ethylenediamine gets added to the reactor, mixed uniformly, and allowed to stand for a full day, resulting in graphene-modified adhesive.
3. The preparation of composite anticaking agent to be used in potassium chloride that is food grade
To reduce the chance of having higher blood pressure it's now possible to add a bit of potassium chloride to substitute sodium chloride from the edible salt. But, during the process of storage and transportation of potassium chloride, the moisture contained in the product can cause breakdown and recrystallization on the powder's surface. This results in crystal bridges at each of the powder's pores and the crystals then combine with each other as they continue to develop. Huge mass. The weakness of fluidity affects its usage in table salt. Thus, to prevent agglomeration, its vital to include a proper quantity of anti-caking agents during the production process.
The composite anti-caking agent used in food-grade potassium chloride is non-toxic, harmless in its color, odor, and colorlessness. It's composed of D-mannitol also known as potassium stearate. It is calcium dihydrogenphosphate. the specific gravity of D'mannitol potassium stearate, and dihydrogen phosphate is (1.25-5): (0.1-0.4): 1. The purity of the D-mannitol, potassium stearate as well as calcium dihydrogen diphosphate, is food grade. Contrary to prior technology it offers benefits of being colorless, or somewhat white, does NOT alter the whiteness of potassium chloride. does not contain cyanideand is therefore non-toxic and is safe.
4. . The production of high-molecular polyethylene waterproof membrane made from polypropylene
Polyethylene Polypropylene is a novel material that has been used in the last few years. Polypropylene is a blend of polypropylene fabric that is non-woven and polyethylene as its primary raw material. It is made of anti-aging compounds and processed using the most advanced, high-tech technology, and new technology. The polymer polyethylene polypropylene composite waterproof roll material with an integrated layer has a substantial friction coefficient, outstanding durability, stability, high mechanical strength Small linear expansion coefficientand a broad temperature adaptability, great weather resistance, chemical resistance, and flexibility. The characteristic is an ideal sustainable product for protecting the environment in the 21st century. The procedure for the preparation of the high-molecular-molecular-molecular-polyethylene waterproof membrane comprises the following steps:
Step 1: Measure the raw materials in accordance to the following percentages by weight including 80-130 ppm of polyethylene resin. Also, 10-20 percent of the talcum powder, 5-10 portions of silica fume. 5-10 parts of glass beads and 8-16 pieces of potassium Stearate. 8-18 pieces, carboxylated, styrenebutadiene latex, 10-20 percent of the anti-aging agent;
Step 2: Put silica fume, talcum powder along with potassium stearate as well as carboxylated styrene-butadiene in a high-speed mixer. Set the temperature to 70-80 degrees C. Stir at a rapid speed for 8 to 18 minutes, and then increase the temperature to 95 to 100 deg C. After that, a glass microbeads made of polyethylene are added to the mixture is stirred with a high rate for 10 to 20 minutes in order to obtain a combination;
Step 3: Insert the mixture into the feeding area to extrude the polypropylene sheet and the plastic sheet completely with the help of the three-roller machine. Then, connect the guide roller onto the tractor, slice the edge, and enter the coiler to create the finished product.
When compared with conventional methods, positive advantages of the invention include synergistic results from an adsorbent polyethylene resin, silica-based fumes and glass microbeads, potassium stearate, carboxylated butadiene latex, anti-aging ingredient, and subsequent preparation steps. especially when high-speed mixing occurs using a specific order for the input of the raw materials is particularly crucial. In combination with the sequence of the invention The performance of the developed high-molecularly polyethylene polypropylene waterproofing membrane exceeds the traditional high-performance waterproofing membrane.
