Abstract

The invention relates to an anti-cracking mahjong tile and a manufacturing technology, and relates to the field of production and processing of mahjong tiles. The mahjong tile comprise a tile body, the tile body comprises a shell body and a back cover, a containing cavity with an opening is formed in the shell body, and the back cover seals the opening of the containing cavity; a placing groove isformed in the bottom of the containing cavity, a magnetic block is arranged in the placing groove, and the containing cavity is filled with a buffering layer; the first buffering layer covers the placing groove and the magnetic block, the first buffering layer adheres to the surface of the containing cavity, and a second buffering layer located on the first buffering layer is located in the containing cavity; a buffering space exists between the second buffering layer and the back cover, and the first buffering layer is an incomplete-heating melamine powder layer. Through the first bufferinglayer and the second buffering layer, when the temperature is changed, the incomplete-heating melamine powder layer has an upward expanding buffering space, cracking of the mahjong tile is avoided, and the technical problem is solved that the mahjong tile easily cracks.

Description

technical field [0001] The invention relates to the field of mahjong production and processing, in particular to an explosion-proof crack mahjong and a manufacturing process. Background technique [0002] The mahjong on the automatic mahjong table is provided with a magnetic block. Because the expansion coefficient of the magnetic block is different from that of the material covering the fixed magnetic block, the situation of mahjong bursting has occurred, which has not been well resolved. Mahjong usually uses melamine powder as the raw material, through high temperature and high pressure molds to make a plurality of shells with the opening upward and the brand name printed on the bottom, then put the magnetic block into the placement slot in the shell, and then add melamine powder or stones, etc. Fill the cavity in the shell with other materials, and finally add melamine powder on the mold at the top of the shell, use a hydraulic press to form the mold at high temperature a...
