Black-Based Quartz Stone Slab is a kind of artificial stone made by die-casting with quartz sand as the main filler. The plate has a hardness of up to 7 Mohs hardness, high temperature resistance of 300°, and beautiful color. The disadvantage is that it is not easy to process, and the fracture cannot be repaired. Basically, it can only be a flat table. As the quartz stone market continues to mature in our country, coupled with the subsidy of CNC equipment. At present, the difficulty of modeling and the problem of seamless splicing have been basically solved! The following introduces the cause analysis and solutions of various quality problems of Black-Based Quartz Stone Slab.

 

Black-Based Quartz Stone Slab

1. Stomatal phenomenon: Black-Based Quartz Stone Slab has round holes of different numbers and sizes on the surface. Reason analysis: The vacuum degree in the press cannot reach the requirement of -0.098Mpa when the plate is pressed, and the air in the material is not discharged. Solution: Check whether the compressor is leaking: close the bleed valve, pump the vacuum to -0.098Mpa, close the valve connecting the pipeline between the compressor and the vacuum pump, and observe whether the pointer of the vacuum gauge moves back. If the pointer moves back, it means that the compressor is leaking, and notify the machine to repair. If the pointer does not move, it means that the compressor is not leaking. Check other possible causes.

 

2. Variety phenomenon: Black-Based Quartz Stone Slab and iron friction produced black. The noise caused by the decolorization of the mirror glass. Reason analysis: 1. The stirring paddle leaks iron, or the iron leaks out of the feeding port, causing the friction between the material and the iron to produce black. 2. The vibration force of the press is not uniform, causing the mirror glass to discolor in some parts of the plate and produce variegated colors. 3. The sundries in the environment enter the board and cause variegation.

 

3. Powder mass phenomenon: Black-Based Quartz Stone Slab has masses of different sizes, only powder and no particles. Reason analysis: 1. The stirring paddle can't stir, and there is material on the side of the mixer that has not been stirred. 2. The material on the wall of the mixer falls into the material. 3. Uneven mixing. Solution: 1. The designated mechanical repairer is responsible for the production and maintenance of the agitator. If the agitator fails to stir, immediately notify the mechanical repairer to replace it. 2. The material on the wall of the mixer is shoveled into the mixer after adding resin, or shoveled out of the mixer after putting the material. 3. The mixer is operated strictly in accordance with the process requirements.

 

4. Uneven particles: Black-Based Quartz Stone Slab has uneven distribution of large particles, locally dense, and partially evacuated. Reason analysis: 1. Insufficient mixing time leads to uneven mixing. 2. Add the color paste before the particles and powder are evenly stirred. The powder and color paste will form agglomerates. If the mixing time is not enough, it is easy to cause uneven particle distribution. Solution: 1. Operate strictly in accordance with process requirements. 2. The large dough must be crushed before distributing. 3. The granules and powder are mixed well in advance in the raw material workshop.
