Zhuhai PUR adhesive contact zhuhai industry PUR adhesive contact in recent decades, pressure sensitive adhesive types have rapid development, acrylate, water glue the constantly emerging of the new type of pressure sensitive adhesive ( The acrylate pressure-sensitive adhesive research and application of common) And gradually replaced the traditional type of natural rubber ( Zinc oxide adhesive plaster) Pressure sensitive adhesive. Main characteristic under the edit good prosperous for you to explain the hot melt glue machine, the working principle of the host: (1) common material: PU, TPU, rubber, EVA, nylon, leather, artificial leather, you can use water-based glue; (5) recipients, according to the principle of first in first out to ensure freshness. 1. Non-toxic, no smell, high transparency, no yellowing; Zhuhai industry PUR adhesive contact technical indicators PH 6. 5 to 7. 5 if the glue on the skin, can clean water and soap. And because of the hydrogen bond and crosslinking reaction, and so cohesive strength is compared commonly big. 2. Soft, good elasticity, resistance to kink deformation; High molecular weight polymer part determines the pressure sensitive adhesive with viscous force, while part of the low molecular weight contribution to the viscous force and peel strength comparison. 3. No crack, long service life, cold resistant high temperature; Zhuhai industry PUR adhesive contact [ 3] High peel strength, with ptfe content than ordinary PET aluminum plating film adhesive save about 30%, effectively reduce the cost. Used by the tool before drying of glue can be used warm water to clean. 4. Have a higher resistance to tear strength and superior electrical properties; Zhuhai industry PUR adhesive contact introducing polar groups in molecular OH, COOH) that produce hydrogen bonding between molecules, and slightly crosslinked network structure, make the copolymer molecular weight distribution is more wide, and broad molecular weight distribution of copolymer adhesive easier pressure sensitive adhesive between the three performance good unity, the above experiments also proves this point. Zhuhai industry PUR adhesive contact because the acrylic copolymer in the particle surface, most of the adsorption on the surface of the particles, and methyl acrylic acid is oil, easy ooze owner chain polymerization inside.
The , essentially perfected by chemical factory, is one of the first home appliance to be widely distributed.
