3) adding an adhesive into the mixed powder to perform low-speed paste mixing, wherein the water content is 70-80% and the paste is in a paste shape, and the paste mixing time is 15-20 minutes;
4) and (3) carrying out compression molding on the pore plate blank: performing mould closing and injection molding, and embedding an ultra-fine metal wire at the gun tip;
5) the low-temperature pre-drying temperature of the plate blank is 45 degrees, and the pre-drying time is 15-20 hours;
6) and (3) high-temperature sintering: sintering the molded blank in a high-temperature kiln, gradually heating to 1570-1590 ℃ in the firing process, then preserving the heat for 4-6 hours, then slowly cooling to room temperature and taking out;
the method for quickly replacing the gun head comprises the following steps:
1) sieving various powders: sieving powder formed by the high-pressure water jet flow energy gun by using a 400-mesh sieve;
2) mixing the screened powder at low speed by a mixer for 15-20 minutes;
3) adding an adhesive into the mixed powder to perform low-speed paste mixing, wherein the water content is 70-80% and the paste is in a paste shape, and the paste mixing time is 15-20 minutes;
4) and (3) carrying out compression molding on the pore plate blank: performing mould closing and injection molding;
5) pre-drying the plate blank with the mold at a low temperature of 45 degrees for 1 to 2 hours, then drawing out the pre-embedded superfine metal wires, and drying at the temperature of 100 degrees for 8 to 10 hours;
6) and (3) high-temperature sintering, namely, sintering the molded blank in a high-temperature kiln, gradually heating to 1670-1690 ℃ in the sintering process, then preserving heat for 4-6 hours, and then slowly cooling to room temperature and taking out.
