Both pinholes and oil holes are produced by chemical thinners, and oil holes often appear when these materials are fused together. If the oil and thinner are relatively small and not fused together, pinholes will occur. Polyresin bathroom accessory manufacturers tell you that this problem usually occurs in the second half of the year. After the slurry is stirred, stratification will occur. There are several ways to solve this problem:
1. Before the production of collar pulp, the amount of oil involved should be controlled, and then used after uniform mixing.
2. In the process of production, use some resin raw materials with relatively high concentration, in order to reduce the layering of slurry water when stone powder is added.
3. Pay attention to the humidity when filling the stone powder, because too much water will cause stratification.
4. Polyresin bathroom accessory manufacturers tell you to strictly control the amount of oil involved. In the environment that does not affect the spray grout, less oil should be added, and the amount of oil involved should not exceed five thousandths. As little as possible.
Second, stomata
In the production of resin handicrafts, for products with very complex structures and too small, air holes are prone to appear at corners with high hollow resistance such as corners, and some air holes even expose the surface of resin products. To solve these problems, some resin handicrafts Manufacturers use the following methods:
1. In the process of fine and complex mold design, the problem of air holes should be considered, and the design should be divided into parts, and air vents should be added at the corners, so as to facilitate the evacuation effect and reduce the probability of air holes.
2. Polyresin bathroom accessory manufacturers tell you to use less white and red raw materials as much as possible to increase the solidification time of resin handicrafts, in order to save enough time to extract the air in the mold.
3. Check whether there is any mechanical failure in the vacuum extractor. It is necessary to ensure that the evacuation speed of the resin handicraft in the vacuum box reaches 0.2Mpa quickly, so that the vacuum can be handled well. The product is to take the vacuum degree to reach 0.2Mpa and then reduce it to 0.08Mpa, and then return to 0.1Mpa. This kind of vacuuming effect is also very good.
4. Polyresin bathroom accessory manufacturers tell you to use some thin resin raw materials or fill less fillers to make thinner pulp raw materials, so that the air in the mold can be extracted cleanly when pumping air, and no air bubbles will appear on the surface of the product up.
