Description:
Basic zinc carbonate(Transparent Zinc Oxide Powder), is a kind of
inorganic carbonate, mainly as a raw materials of ceramic and
lithopone manufacturing. It’s specially used in transparent
rubber products because of its refractive index similar to rubber.
Bellow are the advantages in application in rubber
：
1)It is able to increase the thermal conductivity glue, improve the
thermal conductivity and the curing rate, especially suitable for
hot air vulcanization process.
2)It can improve the stability of the shape of semi-finished
products in the curing process, which is suitable for non-model
products (such as the based products which is the use of continuous
vulcanization technology).
Product Advantages:
Our brand name:
Jewel
JEWEL brand zinc carbonate is very famous in China. It is a wet
process white powdered zinc carbonate. It has been used to
substitute conventional in sulfur vulcanization with environmental
and economical significance. JEWEL basic zinc carbonate is
spotlessly white, pure, and has excellent liquidity and stable
physical and chemical properties.
Comparing to the others, JEWEL has several advantages:
1)Production equipments are made of stainless steel and copper
materials, which ensure products’ consistency and no
impurity.
2)JEWEL production is using hot air drying to make sure the drying
degree of product uniformity, so that the product has uniform
fineness, good fluidity and high specific surface area.
3)JEWEL has low heavy metal content, less than 5PPM. The process is
conformed to environmental protection and economic benefits.
Application:
1)It’s specially used in transparent rubber products and foaming
agent EVA because of its refractive index similar to rubber.
2)Special basic zinc carbonate can be used as a skin protective
agent in medical applications.
3)In the industry, it’s used as light astringent and latex
products, also is compound of calamine lotion. It can be used as
main raw material of rayon production, desulfurizing agent in
chemical fertilizer industry and catalyst production.Â
4)In the oil drilling, basic zinc carbonate reacts with H2S to form
ZnS which is stable and insoluble, and that the mud slurry
performance is not affected after adding basic zinc carbonate into
the mud. So it can eliminate the pollution and corrosion of H2S
effectively, also can be used as corrosion inhibitor and sulfur
removal agent to process H2S in oil and gas wells.
5)Zinc carbonate can also be widely applied to rubber soles,
rubber-plastic product accessories, pipe fittings, rubber plates,
motorbike tires, belts, rubber band, ZPT, desulfurizer agent, zinc
stearate, etc.
