Application Scope and Raw Materials Selection of AZ-40 Zirconia Alumina

The research&development of AZ-40 zirconia alumina is originally designed for stainless steel and titanium alloy grinding, but now its application scope is becoming larger and constantly extending.

In the aspect of coated abrasives: cloth backing, paper backing, thin film, non-woven fabrics, vulcanized fiber sanding disc, etc. Cloth backing zirconia alumina products are not only used for abrasive belt, but also for sanding disc; In the aspect of bonded abrasives: railway track grinding wheel, cutting disc, grinding disc, etc.;

Under 650 ℃, AZ-40 zirconia alumina has a phase change, from tetragonal phase to monoclinic phase, and the increased volume is larger. It is also why zirconia alumina abrasives can not be used to make vitrified grinding wheel whose sintering temperature is greater than 1000 ℃. It is mostly used for resin grinding wheel whose curing temperature is less than 150 ℃). Only good abrasive grains, and no other good raw materials, it will not play all the performances of zirconia alumina abrasives, and also can not make good zirconia alumina products.

In terms of bonded abrasives, it needs the binder with good bonding property and high temperature resistance, and proper coupling agent. Only in this way can zirconia alumina abrasive particles be well controlled. Otherwise, it will no much difference. In the aspect of coated abrasives, it not only needs the resin with good bonding performance and high temperature resistance, but also have good coating formula. Only in this way can abrasive belt achieve or get close to the level of foreign products.
