The main purpose:
Disodium EDTA is an important complexing agent for complexing metal ions and separating metals. This product is used as a bleaching and fixing solution for the processing of color photosensitive materials, as well as dyeing auxiliaries, fiber treatment agents, and cosmetic additives. , medicine, food, agricultural chemical fertilizer production, blood anticoagulant, complexing agent, detergent, stabilizer, synthetic rubber, polymerization initiator and heavy metal quantitative analysis agent, etc. In the chlorination reduction initiation system for styrene-butadiene rubber polymerization, disodium EDTA, as a component of the active agent, is mainly used to complex iron ions and control the polymerization reaction speed.
Package:
25kg environmentally friendly kraft paper woven bags lined with plastic bags, or packaged according to customer requirements, storage should pay attention to sun protection, moisture-proof, fire-proof, and store according to the requirements of non-dangerous goods.
