White Zirconia Ceramic Balls for Bearings Support Media
The ceramic grinding media with different composition and size , and good feature of high impact resistance
They have the advantages of high strength, high stabilities to chemical and thermal circumstances.Â
Applications:
It can be resistant to acid, alkali, salt and all organic solvents. Being used as a support and a covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environmental protection industries, it can improve the distribution of gas & liquid and protect the catalyst from shocking by the rushing fluids.
Features:
High purity alpha alumina and low silica content
High temperature resistance
Lower water absorption
Stable chemical property
Resist corrosion of acid, alkali

Lead-acid Electric Tricycle to the largest number of lead-acid batteries. Lead-acid batteries, the lowest price, but also the most commonly used. Its less contaminated ingredients, good recyclability. The internal battery to wear wall welding connection, high current discharge performance. Battery cover with PP material, shell cover heat seal, to avoid leakage of the battery when used. Grid alloy with multiple corrosion-resistant alloy, the grid is pressure casting, grid corrosion to solve the short circuit
4, the use of advanced plate curing, into technology, improve the binding of active substances and grid, extend battery life
5, the positive plate for the battery tube, negative plate is paste type, with long life, deep charge and discharge performance and other significant advantages
6, the use of polyester fiber pipe and PVC separator can effectively solve the use of pipe rupture and lead to short circuit caused by dendrite, to extend battery life
