Pinhole, oil hole

In the production process of resin handicrafts, there are many small holes under the surface of some products. When piercing it with a needle, some liquid will flow out. This is called an oil hole. If there are many under the surface of the product, The very small holes, which also have some liquid, are called pinholes.
Pinholes and oil holes are produced in chemical sparser, and when these materials are fused together, oil holes often appear. If there is less oil and sparser and there is no fusion, pinholes will be created. This problem will generally occur in the second half of the season. After the slurry is stirred, there will be a layered phenomenon. There are several ways to solve this problem:
1. Control the amount of oil involved before the production of pulp, and then use it evenly.
2. During the production process, some relatively high-concentration resin materials are used in order to reduce the stratification of pulp water when the stone powder is added.
3, pay attention to the degree of moisture in stone powder filling, because too much water will lead to delamination.
4, must strictly control the amount of oil involved, in the environment does not affect the spray, to be less into the oil category, the amount of oil involved should not exceed five-thousandths of an inch, and to do as little as possible.
