Most of the quartz stone plates currently on the market have problems with chromatic aberration. Chromatic aberration is a big problem that plagues various manufacturers. What are the reasons for solving and chromatic aberration?
First of all, from the production process, most of the current quartz stone slab process: resin, colorant, quartz sand, powder ingredients (according to the formula) → agitation → fabric → pressing → curing → thickness → polishing → molding
According to the above process, the causes of chromatic aberration are:
1. The raw materials of the same batch of raw materials, the instability of raw materials is one of the main causes of chromatic aberration. The main reason is that the same batch of raw materials are different due to the origin of ore, so the mineral processing is very important. If the unqualified things are removed, the ore must be stable. In addition, the stone powder cannot be panned by the resin test, otherwise the iron content exceeds the standard. Followed by the addition of white glass mirror glass, the quality of the current market is very unstable, the color is not the same, the most likely to produce chromatic aberration.
2, resin mixing and the amount of color added to the color determines the length of the mixing time, can not be uniform, coloring in the weighing and adding process due to weighing errors and added to the dirty, is also the main cause of chromatic aberration.
3. The acid value of the resin.
4. Improper operation during mixing.
In response to the above problems, the solution is:
1. Strictly control the procurement of raw materials. Regardless of any kind of raw materials, the first batch will be sealed and preserved in addition to the basic conditions (impurities, whiteness, weight, and particle size). When the second batch of raw materials of the same specification type are put into storage, it is necessary to compare them. It depends on whether there is any difference in whiteness, whether there is any difference in particle size, etc., and make a record. For the same number of products, use the same batch of raw materials as much as possible. If you can't press the small plate and the large plate first, you can adjust the approximation. It is best to mix the quartz powder and use it evenly.
2. The weighing of the color material must be carried out at the same time. Two materials should be inspected before the weighing, and the error should be reduced as much as possible. If conditions are met, the machine can be operated by grinding with a three-roll mill, and then poured into the resin barrel. When you must first store the gas, lower the position, pour the resin as close as possible to prevent the toner from splashing. When the resin is stirred, increase or decrease the mixing time according to the amount of the colorant. Once the mixing time is fixed, the same batch number cannot be free. change.
3, the acid value of the resin, as much as possible with the same manufacturer's products, and the same model, to avoid the manufacturer is not the same, the acid value is not the same, causing a certain deviation, affecting the gloss of the board surface.
4. The color difference caused by improper operation of the mixer during mixing, first stir the aggregate, add the resin and stir evenly, stop and clean the mixture around the mixing shaft with the shovel and clear the material on the stirring block, then stir and add the powder. Do not pour the powder on the mixing shaft when adding powder. Pay attention to the residue on the wall around the mixer while stirring, so that each pot is uniform.
In short, there are many reasons for the chromatic aberration of quartz stone plates. This requires managers to find the cause of chromatic aberration in practice in combination with their actual conditions, so as to prevent the occurrence of chromatic aberration and achieve the same length as possible to facilitate the stability of product quality. .
