When we buy plastic pots, we often need to make careful selections to prevent buying fragile plastic pots, because this kind of product is particularly unusable. So, what is the reason for the brittleness of the plastic pot? One is the production of raw materials and the other is the production process.
Let’s talk about the raw materials first. When the raw materials are mixed with other impurities or improper or excessive solvents or other additives, or the quality of the plastic itself is poor, for example, the molecular weight distribution is large, and it contains components with uneven structure such as rigid molecular chains. Excessive occupancy will cause the plastic basin to become brittle.
The second is the production process of plastic basin manufacturers. If the mold temperature is too low during production, the plastic will cool down too early, the weld seam will be poorly fused, and it will be easy to crack, especially for high-melting plastics such as polycarbonate, and the mold temperature is too high. , Demoulding is difficult, and metal inserts should be used as little as possible during production, and brittle plastics with large heat and cold specific capacity such as polystyrene cannot be added to insert injection molding.
To sum up, there are two reasons for the brittleness of plastic basins. This requires more attention to the production principle and production process in the production process, improve production skills, pay more attention to details, and grasp the raw materials. Only in this way can we effectively prevent the plastic basin from becoming brittle.
