COAGULATING/HARDENING AGENT SOLUTION FOR WET SPRAYING METHOD, AND WET SPRAYING METHOD USING THE SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a wet spraying method coagulating/hardening agent solution and a wet spraying method using the solution capable of solving a problem caused by difficulty of checking the discharge of the coagulating/hardening agent solution. SOLUTION: A coagulating/hardening agent solution for use in a wet spraying method of the present invention is used in a wet spraying the method wherein a refractory material at least containing a refractory stock material adjusted in particle diameters to coarse to very fine powder to obtain a kneaded material is kneaded with a predetermined amount of water, the kneaded material is pressure-fed to a spray nozzle and the coagulating/hardening agent solution is added and mixed in the nozzle with the aid of compressed air before the next spraying work. In the solution, the coagulating/hardening agent solution contains a colorant.
