2, chemical characteristics
Fundamental zinc carbonate synthesized by zinc sulfate and sodium carbonate. The chemical houses, in the use of diverse fields, it has accelerated curing, elimination of hydrogen sulfide and sterilization purpose and many others..
creation of sulfuric acid manufacturing method using soda strategy. Solution color is white, bodily and chemical homes of outstanding fluidity and balance the company’s zinc sulfate production workshop approach: coarse dip – oXiHu (West Lake) Dis.dation – alternative – two oXiHu (West Lake) Dis.dation – alternative, assortment of high quality uncooked resources, multi area eliminating technology, very first-class tools, leading technological innovation guarantees that the answer of zinc sulfate purity. Business with excellent quality soda, dissolving, heating, filtration, to make sure the soda ash thoroughly clean without having impurities. From the starting of zinc carbonate synthesis, response situations by means of handle, to guarantee the simple zinc carbonate particle technology beneath point out control synthetic goods utilizing comfortable water rinsing, diaphragm filter push for sound-liquid separation, drying, particle dimension grading, a vibration sieve, EPT, equipment utilized in automatic management, equipment is created of 304 stainless metal. From the method, gear to make certain item overall performance and steadiness the organization resource for natural gasoline, sizzling blast stove drying air passes by way of the filter processing, to keep away from the product seems black, in guaranteeing the product has good flowability and large specific area region water rinsing, soluble salt products is really reduced, up to GMP all merchandise stXiHu (West Lake) Dis.Hu (West Lake) Dis.rds vibration sieve is fineness assure, zinc sulfate pure manufacturing technological innovation so that our products of direct, arsenic, cadmium heavy metals in 10PPM superb gear, advanced engineering, the administration of ISO has developed the superb quality of the gem zinc carbonate.
3, application:
Higher sodium carbonate sort zinc carbonate as pores and skin protecting agent in medication for zinc supplement in feed, but also for the synthesis of substantial purity zinc stearate.
In the market utilized as light-weight astringent and latex items, preparation Calamine Lotion, also can be used for desulfurization agent, catalyst market, pore forming agent. In the rubber items, due to the fact the refractive index of zinc carbonate and rubber near, EPT for clear rubber items, EVA foaming agent as.
4, EPT: 25kg, double EPT, outer plastic woven bag, the internal layer is water-resistant and moistureproof plastic bag.
