What are the forms of the forming density of vitrified bond grinding wheels?

Forming density of inorganic matter (green body) of vitrified bond grinding wheel: this density is only applicable to the formula table, it is purely a theoretical expression, which is based on the removal of flammable temporary binders (such as dextrin) from the weight of the grinding wheel blank, forming (inorganic) density obtained from porogen and water. When calculating the single weight of the grinding wheel, find the given inorganic molding density in the formula table, this density only includes the mass of the abrasive and the binder, and then add the mass of the temporary binder, water and pore-forming agent, and then calculate the actual single weight of the grinding wheel. Heavy.
