the main ones are: normal pressure catalytic hydrolysis, medium pressure catalytic hydrolysis, high pressure countercurrent hydrolysis, saponification hydrolysis, and enzymatic hydrolysis.
Among them, the one with better quality is high-pressure countercurrent hydrolysis. This production process has the best quality at home and abroad. The raw material for hydrolysis is the hydrolysis of fatty acid triesters - fatty acids and distilled fatty acids - the collected components - dusting (turning liquid stearic acid into solid stearic acid).
There are many raw materials for stearic acid, mainly animal and vegetable oils. Different raw materials produce different products. Some products with low requirements have no impact and can be used universally! The stearic acid produced by Shijiazhuang Chemical Industry is available in various grades. We hope that our customers and friends will come to negotiate!
Introduction to the uses of stearic acid
Lubricant for silane cross-linked polymer materials and aldehyde-phenol laminates (paper substrates).
, loosening agent and anti-caking agent for compound fertilizers.
Internal and external lubricants and surface brighteners for hard calendered films.
, can be used as a modifier for road asphalt, and as a dispersing lubricant for modified materials such as carbon fiber.
, can be used as lubricant and anti-adhesive agent for,, B,, and etc., plastic antistatic agent, plastic foaming control agent
, can be used as rubber lubricant, release agent and Dispersant, improves the processability of rubber compounds, improves the dispersion effect of pigments and fillers, and is a bright release agent and calendering aid for sulfonated rubber ().
, can be used as ultra-fine aqueous emulsion dispersion, widely used as sensitizer for thermal paper, etc.
, Compounding agent for plastic pencils (refills) and ink, lubricant for coated paper and wax for precision casting
Stearic acid application industry
, In the production of ink, in order to benefit the paper For glazing and wet printing, it can improve the smoothness, brightness, anti-fouling ability, anti-sedimentation ability, anti-adhesion and dispersion of the ink. This additive is often added, and it can improve the adhesion of the ink on the surface of the printing crystal. properties, anti-stick, anti-scratch and anti-print-through properties. The addition method is: according to the weight of the ink. Just add it during grinding
. Used in thermoplastic and thermosetting powder coatings to achieve smoothness, leveling, dispersion, anti-adhesion, anti-fouling, anti-scratch and anti-settlement. It can delay the settling and agglomeration of pigments and fillers and help the pigments to redisperse. At the same time, the wear resistance, scratch resistance and surface smoothness of the printed matter are greatly improved, especially the smoothness of the product and the anti-sticking property during color printing.
Versatile. In the cosmetics industry, it is an indispensable raw material for the manufacture of general emulsified products, and is used to prepare creams, cold creams, foundation creams, shaving creams, hair lotions and skin care lotions, etc. In the rubber industry, it is a vulcanization active agent for natural rubber, synthetic rubber and latex, and is also used as a softener.
Used as plasticizer, stabilizer and lubricant in the plastics industry. In the textile industry, it is used as a yarn lubricant and a softener in the manufacture of mercerizing paste. It is also used in the manufacture of release agents, polishing pastes, defoaming agents, metal flotation agents, paint flattening agents, wax paper polishing agents, textile waterproofing agents and other products. It is a solvent for oil-soluble pigments and is also used in the manufacture of regular stearate, Raw materials for stearates and stearates such as calcium stearate, potassium lead stearate, etc.
