Successfully developed water swelling rubber production technology

Beijing University of Chemical Technology recently developed a production technology for water-absorbing expanded rubber.

Water swelling rubber is a new functional polymer material.

This product is a combination of non-polar rubber and polar hydrophilic components. It is characterized by maintaining the high elasticity and pressure deformability of rubber, with non-polar surfaces (such as asphalt, plastic, rubber) and polar surfaces (such as cement). Mortars all have good soaking adhesion, can absorb water quickly and expand, and have a stable water retention performance.

The process technology uses three kinds of water-absorbing rubbers produced by the water-absorbing component and rubber blending method. The production process is free of "three wastes". The products can be widely used in tunnels, subways, basements, swimming pools, offshore oil production seals, and can also be used in automobiles. , medicine, food packaging and other fields.

Pearl paper series products are divided into single-sided Pearl light and double-sided Pearl light. At present, Meiliyun mainly produces Pearl embossed raw paper and has developed and produced 12 colors, namely: pink, purple, red, silver and white, milk white, platinum, light yellow, eggshell yellow, gold, gold copper, black and coffee. Gold is currently the largest color used, with more manufacturers and relatively fierce competition. Meili cloud's production machine is a 1760mm long-net multi-cylinder paper machine with a weight range of 95-115g; The main specifications of pearl-pressed raw paper products are 791mm and 893mm rolls. This product is widely used in alcohol packaging, high-end gift box packaging, cosmetic packaging, clothing hangers, desk calendars, calendars, licenses, and front pages. High-grade printing and deep processing. In recent years, the company has developed and produced high-grade beaded plain paper with wood pulp according to the needs of customers. The quality of the product is recognized by dealers and terminal customers. The color is complete, and the basic color system is the same as that of ordinary beaded plain paper.
