The invention provides a method for producing
ceramic tile bonding
mortar by using black
casting sand. The method comprises the following steps: crushing the agglomerated black
casting sand into sandgranules through a
crusher, then removing iron through a
magnetic separator, then sending the iron-removed
sand granules to a high-frequency vibrator so as to remove
adhesive films on the surface of the black
casting sand granules, sending the black casting sand obtained in the previous step to a drum screen for screening so as to select black casting sand
fine powder, black casting sand fine sandand black casting sand medium sand, mixing, in parts by weight, the black casting sand
fine powder, a mineral activator, redispersible
emulsion powder,
hydroxyethyl methyl cellulose and a polycarboxylic acid
superplasticizer at a ratio, performing uniform stirring, then transferring the mixture into a
grinding device for activation and
grinding so as to obtain
ceramic tile
adhesive additives, mixing, in parts by weight, the
ceramic tile
adhesive additives,
cement and the black casting sand fine sand at a ratio, and performing even stirring so as to obtain the ceramic tile bonding
mortar. Theblack casting sand has complete utilization, is applied to production of the ceramic tile bonding
mortar, and has significant economic, environmental and
social benefits.
