Problems solved by technology

[0004] The first is that a lot of manual pasting is required, because the area and length of the paper are not large enough, and splicing and pasting are required;
[0005] The second is that there are corners and corners in the mold, and these corners or four corners are difficult to lay flat release paper, and it is also difficult to paste and fix, so it still takes a lot of labor, and the products prepared by this method There are also cases where the corners are not neat

Embodiment 1

[0027] A high-temperature release agent for foamed ceramics, consisting of the following raw materials in mass fraction:

[0028]

[0029] The dispersant is a silane dispersant.

[0030] The particle size of each material is greater than 325 mesh.

[0031] Said materials are mixed evenly and then mixed with water, the mass ratio of mixing is material:water=3:7.

[0032] The foam ceramic high-temperature release agent is mixed with water, and after mixing, the mold is sprayed by spraying equipment, and the spraying thickness is 0.7mm.

[0033] The high-temperature release agent for foamed ceramics is mixed with water, and the mold is sprayed by spraying equipment after mixing. The sintering temperature of the sprayed coating is 910 degrees, while that of the foamed ceramics is 1100 degrees. The sprayed coating is sintered earlier than the foamed ceramics.

Abstract

The invention relates to a high-temperature release agent for foamed ceramics and a use method thereof, belonging to the field of preparation of foamed ceramics; it consists of the following raw materials in mass fractions: 5-15% of montmorillonite; 3-10% of dolomite; 3-3% of talc powder ‑10%; alumina powder 65‑70%; dispersant 0.1‑0.5%; calcite 1‑3%; magnesia clay 5‑10%; lithium china stone 1‑3%. Use foam ceramic high-temperature release agent and water to mix and then spray. This technology can reduce a lot of manual labor. Normal spraying equipment can be used for spraying, which can greatly improve work efficiency. At the same time, the spraying is even and there is no cutting seam. All corners of the mold can also be sprayed evenly, which is not possible with pasting.

Description

technical field [0001] The invention relates to a high-temperature release agent for foamed ceramics and a use method thereof, belonging to the field of preparation of foamed ceramics. Background technique [0002] With the development of science and technology, the application rate of foamed ceramics is getting higher and higher, and foamed ceramics are also more and more accepted by people. Zhou Suozhou and the current foamed ceramics are all foamed by molds. It is a well-known problem that the mold and the foamed sheet stick together during the foaming process. If no measures are taken, the mold and the foamed sheet will easily stick together during the sintering process, and it will be difficult to separate the mold and the sheet. If Forcible separation can easily damage the mold and the plate, or the mold cannot be used, or the plate is defective and becomes a defective product; [0003] At present, the effective means in this field is to use release paper to separate ...
