When we buy injection molding parts, sometimes we will encounter the situation of odor, which is not a small impact on the user's health. So, we are in the injection molding process, and how to avoid odor? The following Kexiang plastic mold manufacturers small make up a simple to understand.
1, strictly control the use of additives
Polyurethane foam production process used in the catalyst tertiary amine will bring a strong odor, but also in the car interior window fogging, we can find these amine substitutes using polyhydroxy compounds, polyhydroxy compounds are not only components of the polyurethane molecular chain, but also the same catalytic activity, some polyhydroxy compounds and even be able to replace half of the tertiary amine catalysts, in this way, injection molding and processing of the product odor is The odor of injection molded products will become lighter.
2, choose more pure resin
Many plastic molds, especially in PVC, styrene, polyethylene acetate and acrylic ester, residual trace monomer will occur unpleasant odor, if the selection of its own odorless resin, the effect will be better.
3, pay attention to the use of adsorbents
In the polymer if filled with a small number of zeolites, you can play the effect of removing plastic odor. Zeolite has a lot of crystalline vacancies, these vacancies can capture those small molecules of gas with odor.
