Acid and alkali resistant high-whiteness glazed brick

The utility model discloses an acid and alkali resistant high whiteness glazed brick which comprises a base, gridding cloth arranged on the surface of the base body in a composite mode and an acid and alkali resistant glazed layer arranged on the surface of the gridding cloth, the base is formed through pressing of a high-tonnage pressing machine, and the acid and alkali resistant high whiteness glazed brick comprises a base body and an inner groove formed in the lower end of the base body. The nail column is arranged on the inner groove, and the length of the nail column exceeds that of the inner groove; through cooperation of the inner grooves and the nail columns, the attaching strength of the base under the action of putty can be effectively enhanced, meanwhile, the nail columns distributed in a staggered mode can enable the base to bear large pressure, layering and separation of the gridding cloth and the glazed layer caused by cracking of the base are avoided, and the structural high strength and the pr
