Notice to ordering goods.
a) When ordering goods, customers should introduce the radical situations of the equipment,
including the sizes of reactors, and the operational temperature etc.
b) Customers should provide the specification, types, and the total content of Si, Al related to the required product.
c) As the inert ceramic ball belongs to the natural tight stacking in the reactors, customers should consult with our technological staff to determine the amounts according to the practical loading volume, and remain 15-20% margins
