Sand blasting process includes:
1, good gloss (100%) : glass sand.
2, half gloss (50%):50% glass +50% gold steel sand.
3, dull (0%) : gold steel sand due to the use of different resin materials, and injection forming conditions are different, single sandblasting treatment can fully adjust its luster, so it must be repeated many times.
Because of sandblasting machine abrasive impact to the workpiece surface and the cutting effect, make the surface has a certain cleanness, make medium with different surface roughness, sandblasting derusting machine so as to improve the mechanical properties of the workpiece surface, improved its anti-fatigue performance, the bonding strength increased with the workpiece surface, extend the durability of the coating.
The purpose of the mirror:
Rolling device in between the winding device and set up the frame, light on a light frame set mirror roll, mirror roll into the direction of cloth rack set cloth guide roller and the distribution of roll, mirror roll out cloth direction set cooling roller, in the light rack set cooling roller, in the light rack set with mirror roller with one or two of calender rollers, The supporting roller and the rectifying device are arranged around the calendering roller, the supporting roller and the rectifying device are outfitted with a felt ring, and the pressure regulating mechanism is arranged at both ends of the calendering roller of the rotary sandblasting machine.
The utility model is mainly used for ironing the surface of artificial leather, improving the surface grade of the finished leather, increasing the gloss and brightness of the surface, and brightening the place where the leather surface pattern is raised and producing the effect of no light at the bottom of the trench. The surface effect of artificial leather is made up of a large diameter super mirror heating roller combined with a pressure roller in the high temperature resistant felt. The relationship between the artificial leather and the mirror roller is adjusted by adjusting the pressure, temperature and ironing time.
