Product Description

Polyacrylonitrile is also a high strength, good elasticity, oil, acid and alkali materials. Although the monomer is a toxic Raw Material, but after polymerization polyacrylonitrile low toxicity. Artificial blood vessels made of polyacrylonitrile fibers have been widely used clinically. In recent years, the development of a copolymer of acrylonitrile and cationic monomer, copolymer spinning, and then form an ion complex with heparin, such fibers have direct anticoagulant properties. Membranes made of copolymers of acrylonitrile and sodium methallyl sulfonate have good permeability. An integrated flat artificial kidney made from this membrane is widely used clinically due to its high clearance of medium molecular weight uremic toxins. In addition, polyacrylonitrile hollow fiber type artificial kidney has also been made.

Production methods

Industrial production of polyacrylonitrile mainly suspension polymerization, solution polymerization (monomer and initiator dissolved in a suitable solvent in the polymerization reaction). Acrylonitrile was dissolved in dimethylformamide and treated with azoisobutyronitrile or azoisobutyronitrile as an initiator to polymerize at 50 to 60 ° C. When the conversion reached 90%, the unreacted monomer was recovered and filtered Solution, dubbed a certain concentration for spinning. In addition, precipitation polymerization can also be carried out in aqueous solution to initiate the polymerization with water-soluble potassium persulfate as an initiator. The resulting polymer is continuously precipitated from water and filtered to obtain powdered polyacrylonitrile.

Product expansion

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.

2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period, it can not be taken directly by patients.

3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.

4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, Additives, and other intermediates.

5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
