Maijisen's additives help you solve the surface problems of PVC plate

·How to solve theproblem of PVC plate performance below the standard？？

PVC plate performance not up to standard? Maijisen additives are here to help! Our GM/DB series additives are specially developed for PVC products, aiming to effectively improve the performance, stability and surface quality of PVC foam boards, carbon crystal boards, decorative boards and other related profiles. Many manufacturers often encounter problems such as insufficient mechanical strength, poor heat resistance, insufficient toughness, unstable processing, poor surface finish, or unqualified impact resistance in actual production. These issues not only affect product qualification rate and production efficiency, but also increase costs and damage brand reputation. With professional additives and complete technical solutions, Maijisen can help you quickly locate problems and achieve stable performance improvement.

①Analyze the reasons for the substandard performance

First of all, it is necessary to accurately confirm the specific indicators that fail to meet the standard. Common problems include insufficient rigidity and strength, low impact resistance and easy breakage, poor thermal stability leading to deformation or yellowing, insufficient foaming uniformity, poor surface brightness, poor processing fluidity causing low output or high rejection rate, and dimensional instability leading to warping or deformation. Only by clarifying the real cause can we avoid blind adjustment of formula or process, and achieve targeted improvement with high efficiency.

②Select a suitable processing aid

According to different performance defects, choose Maijisen additives with targeted functions.GM605 and GM61 are excellent processing modifiers that can significantly improve melt strength and processing fluidity, helping to enhance plate rigidity, surface flatness and overall stability. DB1 and DB6 focus on strengthening toughness and improving processing performance, suitable for plates that require higher strength and better extrusion stability.  

DB 3 specializes in enhancing surface brightness, smoothness and toughness, making the board appearance better and more durable.

NCR61 is a high-efficiency foaming modifier that can promote uniform and delicate foaming, increase impact resistance, extend stable startup time, reduce defects, and improve production stability.

③Adjust the formula

On the basis of the original formula, introduce the corresponding Maijisen additives in a reasonable proportion. The dosage should be adjusted step by step according to equipment conditions, material characteristics and target performance, so that the additives can fully exert their effect. It is recommended to keep the proportion of other raw materials stable during the test to avoid mutual interference between multiple variables, which makes it difficult to judge the real effect. Scientific formula adjustment can quickly improve product performance without significantly increasing costs.

④Optimize the production process

Formula improvement needs to be matched with appropriate process parameters to achieve the best effect. According to the characteristics of Maijisen additives, properly adjust extrusion temperature, screw speed, traction speed, cooling method and cooling temperature. Reasonable process settings can make the plasticizing effect more sufficient, foaming more uniform, internal stress smaller, and the plate more stable in size and appearance. Process optimization can greatly improve product stability and reduce the probability of substandard performance.

⑤Strengthen quality control

Establish a complete production quality control system to detect key indicators in real time during the production process. Regular sampling and testing are essential to monitor strength, toughness, heat resistance, foaming condition and surface quality. Once abnormal conditions are found, adjust formula or parameters in time to avoid large-scale unqualified products. Strict quality control can effectively reduce the rejection rate, stabilize production and ensure that each batch of plates meets customer standards.
