Introduction to the main production process of acrylic products

by:UNQ     2021-03-31
Acrylic products are essentially methyl ester polymers. According to the polymerization procedure, product polymerization can be divided into two steps. The first step is to make a slurry, and the second step is to polymerize the slurry. In order to obtain products with specific specifications and quality standards, the product The polymerization process also requires some auxiliary processes. The acrylic material polymerization process is divided into five stages: the first stage is the slurry production stage. The operator needs to put triggers, plasticizers, and mold release agents into the acrylic material, according to the conversion rate. Ten slurries can be made at once. The conversion of plexiglass processing slurry can shorten the production cycle and improve the production efficiency. The operator can use the high temperature decomposition trigger to shorten the polymerization time and trigger time, which can activate the material and increase the production chain. The operator can stir the material to accelerate the heat conversion. By transferring more polymer in a short time, the operator can increase the viscosity of the material monomer and shorten the gel time. The operator can increase the viscosity of the material by using the degradation method, which is convenient for the production and processing of acrylic products. The operator can reduce the volume of the polymer material, and the final product specific gravity will be less than 1, and the final product specific gravity will exceed 1.

If the polymer shrinkage ratio is large, it will directly affect mold production, mold injection and material polymerization. Therefore, operators need to pay attention to controlling the polymer to maintain the specific gravity below 1, which can reduce the expansion and expansion of the polymer. shrink. If the viscosity of the slurry increases, the operator can appropriately reduce the injection of the mold to avoid leakage of the mold during the injection process and cause the loss of the slurry. The second stage of plexiglass processing is the mold making stage. The operator needs to place the acrylic product between the horizontal glass. The horizontal glass needs to be cleaned before placing it. After cleaning, the horizontal glass is placed in a ventilated place to dry to ensure the surface of the horizontal glass. In a dry state. The glass should be equipped with rubber strips or rubber tubes around the glass. The rubber strips and rubber tubes need to be wrapped in cellophane and then placed under the glass, which can effectively control the gap between the glasses and adjust the thickness of the product. The third stage is the mold infusion stage. After calculating the weight, the prepared slurry is injected into the mold, and the air in the mold is completely discharged, so that the slurry can fill the mold and facilitate the opening and closing of the product.
