    PVC profile manufacturers talk about the causes of cracks

    PVC profile bubble. Cracks and pockmarks (1) the main reasons for the above are as follows: 1) the moisture and volatile substances contained in various materials are seriously overspended, and can not be fully swept out in the extrusion mixing process, and the volatiles are still retained in the material, and bubbles, cracks and pockmarks will appear inside or outside the profile after heating. Once this kind of phenomenon appears in production, the influence of raw materials should be eliminat

    Can you distinguish PVC profiles from profiles? I believe that many people or people who have just come into contact with aluminum profiles are always confused about profile and profile, and can't make out the difference between the two. Today, Xiaobian explained the difference between the two profiles to the silly friends. Extrudate: it is an object with certain geometric shape made of iron or steel and materials with certain strength and durability (such as plastic, aluminum, glass fiber, etc.

    In the production of SG-5 resin with low polymerization degree, the selection and formulation of PVC materials should be selected. The higher the degree of polymerization, the better the physical and mechanical properties and heat resistance. However, the poor fluidity of the resin leads to certain difficulties in processing. Therefore, SG-5 resin with viscosity of (1.7 ~ 1.8) × 10-3 Pa? S should be selected. Lead stabilizer is generally used for hard tube, which has good thermal stability and i

    Introduction to plastic profiles: plastic profiles are listed as one of the building materials in China due to their excellent thermal insulation performance. In the production process of plastic profile, what problems should be paid attention to to to ensure the quality and process of profile. Application of plastic profile: plastic profile products are widely used: window frame, stair handrail, raceway, skirting board, special-shaped pipe, etc. The raw materials are mainly hard PVC, a few are

    Advantages of plastic profiles: 1. Thermal stabilizers: plastic profiles are thermosensitive plastics, so in the production and processing of plastic profiles, thermal stabilizers are essential. The metal salt in the thermal stability agent can absorb HCl decomposed from PVC, so it can delay the decomposition speed of plastics and extend the decomposition time. Compound lead salts are used in the production of plastic profiles, which have high thermal stability efficiency and low price. 2. Lubri

    Plastic profile manufacturers talk about crystallization reasons

    2020-12-17 832

    Plastic profile is a very common product in our production. Let's talk about the reasons that affect the crystallization of thermoplastic plastics. 1. According to the phenomenon of no crystallization when it condenses, thermoplastic plastics can be divided into crystalline plastics and amorphous (also known as amorphous) plastics. The so-called crystallization phenomenon refers to the phenomenon that the molecules move independently and are completely in a disordered state from the melting stat
