The invention discloses a slurry dipping method of enamel preparation technology. According to the slurry dipping method, indoor relative temperature is controlled to be 25 DEG C, and relative humidity is controlled to be 65 to 75RH. The slurry dipping method comprises following steps: a first slurry and a second slurry are prepared respectively; fixed wax moulds are fixedly arranged on supports; the wax moulds are washed; the appearance of the wax moulds are examined; and slurry dipping is carried out. Compared with the prior art, the slurry dipping method comprises following advantages: the two different slurries are prepared, the wax moulds are dipped in the slurry containing a surface layer additive firstly so as to improve coating performance; the outer and the inner of the wax moulds are uniformly coated with fine sand so as to improve the strength of mould shells; the wax moulds are dipped in the first slurry for one time, and in the second slurry for three times, wherein each time of dipping is carried out when complete air drying is realized, and the wax moulds are also coated with medium-coarse sand and coarse sand so as to improve structure strength.
Description
technical field [0001] The invention relates to the technical field of enamel production, in particular to a paste dipping method in the enamel production process. Background technique [0002] There are many tools for enamel production, and dipping is one of them. [0003] The slurry dipping process is to form a mold shell by dipping slurry on the surface of the wax pattern, and then heat it to remove the wax pattern inside, and then pour copper water into the mold shell to form a copper tire. [0004] Due to the high temperature of copper water and the weight of the formed copper tire, there are high requirements for the high temperature resistance and strength of the mold shell. The traditional dipping process has defects such as limited strength and uneven thickness of the modules, which lead to the bursting of the mold shell when pouring copper water. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies of the prior...
