One, the rare earth application in spin and leather industry
Rare earth is used at spin and leather industry is our country Scientists and Technologists develops the provides distinguishing feature alone rare ground that give to use a field, perspective is very wide. Through old research and promotion, engineering technology also becomes better day by day, gained obvious economic benefits and social benefit. Rare earth basically is used at leather tan to make in spin and leather industry, the printing and dyeing of fur coloring, cotton spinning, wool spinning and synthetic fibre. Because rare earth coloring is to be on the foundation of original coloring technological process and equipment, through a kind of when be improved appropriately and form new technology, this laid a foundation with respect to the promotion that is craft of rare earth coloring.
1 rare earth is aided catch
Rare earth (basically use chloridize rare land) add in acid dye (include strong acidity, weak acidity and acidity mordant dye) in, rise to aid catch action, can raise dye-uptake, adjust dye and fibrous affinity, raise colour fastness, improvement quality of fibrous colour and lustre, exterior and feel pliability, managing dye and reduce an environment pollution, reduce labor intensity and reduce motivation to use up etc.
The promotion that rare earth coloring uses already had 10 old histories. Rare earth already applied in black silk ribbon of abb, fine, pure cotton, polyamide fibber, real silk, stick coloring of all sorts of natural fiber such as cotton of glue, man-made, flax, ramie, chemical fibber and its blending to aid catch. The enterprise has popularized hundreds in 20 many provinces, city, municipality spin after Ceng Xian rare earth is aided acquire a technology, gained remarkable economic benefits and social benefit. Use rare earth to aid catch, dye-uptake rises, auxiliary dosage decreases, the dosage of water also decreases, reduce and reduced sewage discharge capacity and processing cost.
2 rare earth aid tan
Rare earth aids tan agent to be able to improve the grade of leather not only, and can reduce cost. Use rare earth to mix tan agent tan to make leather, can replace a vanadium of share out bonus, reduce chromic dosage in great quantities, reduced the pollution of the liquid waste in curry industry to the environment. Mix the product that tan agent tan makes with rare earth, change side is meticulous and tight, leather board is soft, fur colour and lustre is shining fleeciness, feel is good, be able to bear or endure wash, peculiar smell decreases, pull fight intensity to reach burst apart the level that force and chemical function all reach pure chrome tanning to make, have more remarkable economic benefits and social beneficial result.
2, the rare earth application in plastic industry
"Since 75 " , rare earth ever had obtained great progress in the application of this domain, our country develops rare land early or late plastic stabilizing agent, rare earth adds MC nylon to wait.
