The performance and advantages of cold glue system

The traditional method of hot melt adhesive system is to mix high molecular weight polymers and low molecular weight gums to achieve the desired overall performance. At present, the biggest feature of the hot melt adhesive system is that the resin and polymer are based on petroleum raw materials.At

Vacuum plasma surface treatment features

Plasma, the fourth state of matter, is an ionized gaseous substance composed of atoms deprived of some electrons and positive and negative electrons generated after atoms are ionized. Its energy range is higher than that of gas, liquid, and solid matter. There are electrons, ions and neutral particl

Due to the low surface tension of most plastic materials, many designs in the past tended to adapt to the use of materials. Nowadays, as long as the surface can meet the requirements of spraying or bonding after a certain plasma surface treatment, it can be used first. This material.In recent years,
