Ricia oil contains a lot of ricic acid (more than 80%), so many unique properties:
1. It is easy to dissolve in ethanol, which is difficult to dissolve in petroleum ether. This feature is more likely to distinguish between castor oil from other grease.
2. The viscosity is much higher than that of the general oil, and 25 is 680 cps, the viscosity index 84, the friction coefficient is very low (0.1).
The fluidity of castor oil is good, and the refined castor oil can still flow in -22.

Dissolving function: soluble in water and some solvents, such as ethanol/water, propanol/water in appropriate proportions. The aqueous solution has surface activity. High transparency and stable function. Different standard products have different gel temperatures and solubility changes with viscosity. The lower the viscosity, the greater the solubility. Different standards of HPMC have different functions. The dissolution of HPMC in water is not affected by pH.

TDI is the abbreviation of toluene diisocyanate. TDI is a polycyanate widely used in industrial production. It is a polyurethane material and an important basic material. Mainly used to make flexible polyurethane foam, polyurethane elastomer, coatings, adhesives, etc.
TDI (toluene diisocyanate) is one of the commonly used polyisocyanate, and polyisocyanate is an important base material of polyurethane (PU). The TDI commonly used in the polyurethane industry is a mixture of 2,4-TDI and 2,6-TDI isomers, including three commonly used grades.
It has relatively low solubility to non-polar gases H2 and N2 during the absorption process, so the loss of pure gas is also small. This feature further constitutes its bright future as a decarburization solvent.
Ammonia desulfurization technology (abbreviated as ammonia desulfurization) is similar to gypsum desulfurization, and it is an advanced, efficient and economical desulfurization system.
The principle of photocatalysis is based on the oxidation-discount capacity of photocatalysts beneath mild conditions, which can reap the purpose of purification of pollution, cloth synthesis and transformation. usually, the photocatalytic oxidation response makes use of a semiconductor as a catalyst and mild as an power source to degrade organic rely into carbon dioxide and water.
Good safety factor. Piping reflects that it can prevent the occurrence of explosion caused by partial over-temperature, and it is the safest and most reliable process route for ethylene oxide.
Acrylic paint is a one-component self-drying weather-resistant and anticorrosive paint made by advanced technology based on traditional acrylic resin and added with long-life chlorosulfonated polyethylene rubber, weather-resistant pigments and fillers, and weather-resistant additives recognized by China and foreign countries.
This product is a white powder with strong hygroscopicity. It is prone to deliquesce when exposed to the air and absorbs carbon dioxide to generate potassium carbonate.
Bubbles have a great impact on industrial production. In the production process, foams generated due to various reasons need to be treated with defoamers.
