Sizing enzyme for paper pulp industry

Details:

Liquid surface sizing enzyme uses biotechnology to directly handle the raw starch to achieve the requirements of the surface of the papermaking surface, which can replace the surface of the surface of the paper industry -oxide starch or transgender starch.

Mechanism
It is a biological degeneration process with starch. The α-D-1,4 glycoside bond in the middle of the starch molecular chain is randomly cut off, thereby reduced the starch molecular chain and the viscosity is reduced. When the viscosity meets the requirements, the temperature increases to 95 ° C, it will be inactivated and lost. The reaction can be terminated. The viscosity can remain stable. Its biggest advantage is that the viscosity value can be arbitrarily adjusted according to the production requirements and the viscosity is stable.

Physical and chemical nature
◇ Appearance: brown to light brown liquid 
◇ Smell: Mild fermentation odor
◇ Density: 1.02-1.20g/ml 
◇ pH value: 5.0-7.0

Product advantages
◇ The operation process is simple, does not change the pH value, does not affect subsequent production, non -corrosive, non -pollution and other advantages; it can replace other traditional chemical adhesives.
◇ Increase the smoothness and surface strength of the paper pages, reduce the phenomenon of hair loss of paper surface, and improve the printing performance of paper.
◇ Be high and low sticky, stable viscosity, good membrane, increase the amount of glue in the glue, reduce the slurry consumption, thereby reducing the cost

Instructions for use
1. Add a certain amount of water and starch to stir well in the boiled tank;
2. Add biological enzymes and stir well;
3. The traffic steam begins to rise and boils;
4. Control the heating curve according to the viscosity of the starch;
5. The insulation above 95 ° C for 15-20 minutes to achieve enzyme charging;
6. The use temperature is generally controlled at 55-70 ° C. Special circumstances are determined according to the requirements of the manufacturer;
Continuous boiling procedures are basically the same as intermittent
7. Add dosage: 50-150g/ton dry starch powder,
The best amount needs to be determined according to the actual situation test

Packing, storage and shelf life
◇ Packaging: 25kg/barrel or customized according to customer requirements
◇ Storage: Storage when avoiding sunlight and cooling and dry conditions, the best storage at 4 ° C cold storage;
◇ Hempeible period: 6 months under normal temperature conditions for 1 year under 4 ° C refrigerated conditions, and the loss of activity does not exceed 10%
Precautions
◇ Under normal circumstances, it is non -toxic and harmless and low -corrosive, but it should be avoided or splashed into the eyes, nose and mouth, etc., and the skin should be rinsed with water immediately with water.
◇ Avoid contact with oxidant, reducing agent, and alkali, avoid mixing. During the handling, remove lightly to prevent the packaging and container from being damaged.
