Product name:Tyre specific zinc oxide
Product catalogue: zinc oxide
Product introduction: high dispersivity can improve the tear resistance, anti-cracking, tear performance, stretching strength of the rubber. The tyre specific zinc oxide can be used as curing catalyst and strengthening agent in tyre production which can improve the binding property of the rubber, steel wire and the cord, and the service life of the tyre. About 5% zinc oxide.


Basic property:
Molecular formula:Zno Molecular weight:81.39
White or fine spherical powder, specific gravity 5.5-6.5g/cm3, specific surface 8 m2/g, granularity 0.15-0.7μm, refraction index 1.95-2.05, specific heat 0.0915c/g℃ at 20℃, meltingpoint 1973℃, it has the phenomenon of evaporation at 1000℃.
Chemical property:
① zinc oxide can be restore to the original state by carbon, carbon monoxide and hydrogen at high temperature.
② Zinc oxide is an amphoteric-oxide, which is slight soluble or insoluble in water. It generate relevant arsoniumsalt after reaction with acid, Zn(OH)2 after reaction with alkali and basic zinc carbonate after reaction with carbon dioxide and other acid gases.
Execution standard: HHXPQB—YHX(LT)—2005

Application:
high dispersivity can improve the tear resistance, anti-cracking, tear performance, stretching strength of the rubber. The tyre specific zinc oxide can be used as curing catalyst and strengthening agent in tyre production which can improve the binding property of the rubber, steel wire and the cord, and the service life of the tyre. About 5% zinc oxide.
Package, transport, stockpile:
Polywoven bags with polythylene film bags inside or waterproofing paper bags, net weight: 50kg/bag, dimension: 580 × 1250mm.
It should have covering during the transportation to prevent rain and damp.
Keep away from Alkalis and acid during transportation.
It should stored in dry and ventilated place.
It is strictly prohibited to contact with alkalis.
According to the above storage conditions, the storage time of the enclosing zinc oxide is half a year since its production date. When it comes to an end , it still can be used if it can meet the requirment of this standard after inspection.
