The starch granules of carton binder are fully stirred under the action of water at a certain temperature. They absorb the surrounding water under the catalysis of caustic soda and swell gradually from several times to tens of times to reach the final (gelatinization temperature). As the temperature rises, the starch granules begin to collapse and gradually disperse into small pieces, when soaked into the surface paper and core paper. When the temperature rises, the water content of the starch grains evaporates and is partly absorbed by the surface paper and the core paper, so that the initial adhesion proceeds rapidly. The adhesive binds the inner paper, the core paper, the corrugated paper and the surface paper as a whole to reach the goal. To the purpose of adhesion.
It has the following characteristics:
1, permeability is strong: permeability is good, is hard to stick paper products nemesis. No moisture returning, no color change: corrugated cardboard box is not moisture regain after drying, it does not fade, it is resistant to compression and no mildew.
2. Reduce costs: less table competition, high adhesive strength, can reduce your production costs, for your business to create higher economic benefits, so as to realize self-worth.
3, strong adhesion: high adhesion strength, more than other products. The hygienic standard conforms to the requirements of the state health department and completely meets the requirements of storage in humid environment such as refrigerators and export packaging for marine transportation.
4. Long storage life: Helong brand reinforcing agent can be applied to various kinds of glue-making machinery and equipment, and the glue produced will not be thinner or thinner at high temperature. It can be stored for 7-10 days to continue to use.
