Fish feed processing is a concern of farmers, and the processing methods of fish feed are mainly divided into physical and chemical and biological processing methods. Based on different raw materials, we now introduce several common processing methods. 1. Animal block feed. It should be chopped or chopped during use, added to the bonded feed, made into dough or fed with other feeds. Do not cook, otherwise it will reduce the nutritional value. 2. cockroaches, maggots, and worms. Insect small animal feed can be freshly fed or processed into dry powder. 3. Animal blood. Animal blood is rich in protein and can be cooked or directly mixed with other dry powder feeds. 4. Cake feed. When feeding the fish, it must be crushed, soaked, and refined before use. 5. Bran, dregs feed. Feeding small fish species should be soaked in soft refining. For adult fish, it is advisable to moisten the bran mixed water and ferment it until it has a wine flavor. The residue can be freshly fed or dried. 6. Cereal feed. The grain feed has better feeding effect after germination, and the bud feed has the highest nutritional value when it is white. 7. Green feed. Generally, it can be fed by washing away the sediment. When feeding small fish, it should be chopped or beaten. After beating, add 0.2% salt, which can be used for both fertilizer and fish. If it is chopped and cooked, mix with bran, soda and other concentrates, the fish prefers to eat. Green feed can also be used for silage. 8. Fecal feed. The fecal feed can be fried or dried and ground, and used in combination with other raw materials, but the ratio should not be too high. Usually chicken manure should not be higher than 40% to 50%, cow dung is not higher than 50% to 70%, and pig manure is not higher than 30% to 50%. 9. Fish pellet feed. It is usually subjected to processes such as pulverization, compounding, agitation, granulation and drying. When there is no feed machine, a small amount of processing can be performed by a soil method such as a meat grinder, a sugar-coated machine, or a noodle machine. The particle diameter varies depending on the size of the fish, and is generally 2.5 to 8 mm and is 1 to 2 times the diameter.
High chlorinated Polyethylene Super - HCPE
Molecular Formula: [CH2-CHCl-CH2-CH2] n
EINECS No.: 208-407-7
CAS NO. : 63231-66-3
HCPE is a type of Chlorinated Polymer which contains chlorine at 65-69%. It is transparent, hard and brittle thermoplastic resins. It has high chemical stability, good salt water resistance and good ultraviolet resistance. It is readily soluble in organic solvents such as toluene, xylene and esters, forming a colorless to pale yellow, transparent solution. When this solution is applied to the surface of metal, concrete, paper etc., the solvent readily vaporizes at room temperature to leave a transparent, hard and lustrous glass-like film. This film resists the permeation of moisture and oxygen gas, and shows high resistance to various chemicals such as acids and alkalis. It protects the substrates from corrosion, and also serves as a top coating for decorative purposes.
HCPE can be used as gravure printing ink, the binder of heavy-duty anticorrosion paint, waterproof paint and the component of adhesives. Particularly, due to its high corrosive resistance to Cl-, it is especially suitable for being used on vessels, docks, containers coating. The paint made of HCPE can be used in chemical equipment, oil field pipelines, offshore facilities, ship coatings, metallurgy and mine, salt industry, fishing ground, wastes treatment, transportation facilities, container and electrical equipment. High molecular weight HCPE grades such as NVH -60 and NVH -120 are our unique products which are developed for all kinds adhesive for PVC pipe, pipe fittings, plates, sheets etc.
NV series are produced by our newly invented hydrochloric acid phase technology, in which no organic solvent such as carbon tetrachloride is involved, resulting no destruction to ozone layer and no harm to the operators health.
