The use of strong catalyst (abbreviation as desiccant)

The main factor that distinguishes cold-strength, high-drying, fast-drying starch binders from other binders is the selection of a "stiffened catalyst."

The strong catalyst is formed by polymerization of several salts and organic-inorganic compounds. In the adhesive and production process, as long as it is suitable for use, it not only accelerates the reaction speed, but also chemically reacts with oxygen in the air after the sizing. The flocculation crystallizes quickly, accelerates the speed of the adhesive conjunctiva, shortens the drying time of the carton, and improves the strength of the cardboard.

The bonding speed of the adhesive (prime stick, full stick, breakage fiber) is several times higher than that of the same starch gum. And cardboard, high hardness, stiffness, number of strong catalyst in the binder per ton of water less than 5Kg less than the effect, the amount of water per ton is higher than 13Kg, adhesive film is too fast, medical cardboard degumming phenomenon. So we must strictly control the proportion of placement. The normal dosage standard is 6 ~ 12Kg/ton water.
