Product feature

At present, many manufacturer use adding a large amount of starch to make surface sizing in order to improve the strength of paper. But due to the skyrocketing price of the starch and the greater the dosage, the cost become higher, but the strength increase is limited, thus caused the increase of production cost and reduce the profits Our company developed the water resistant starch agent, this product cost is l/3 less than starch. On the one hand, it could replace starch and Liquid surface sizing agent after adding this product. On the other hand, the effect of this products is higher than starch, so it’s widely adopted by all kinds of papermaking enterprise. This product is mainly used to increase the strength of paper and paperboard, can effectively increase the paper's hardness. resistance to break, ring crush strength, water resistance and other physical indicators, such as water resistant up m 2-5 minutes does not absorb water.

Technical requirements

Appearance: white powder Main content 98% Ionic : cationic

Water solubility: soluble in cold water PH value: 6-8 .

Technical conditions

(One, the use of surface sizing)
1. Amount: Can instead of 15%-20% of the amount of starch used in surface sizing starch,the recommended dosage is 10-20kg of one ton paper,or according to your production conditions.
2. Process of adding: After gelatinized together with the starch, could use in surface sizing process, no need to change the original sizing methods.
3. Methods of Adding: Gelatinized together with the starch, also could sprinkle the dry powder evenly in the sizing liquid, be sure to sprinkle slowly and evenly.
4. Order of Adding: Gelatinized together with the starch--- put in surface sizing agent--- other auxiliaries---coating.

(Two, adding in paper pulp)
Taking a certain amount of starch strengthening agent, about 5-10 times dilution with water. Throw mm the head box with metering pump. or adjust the dosage according to the specific production situation,the general amount of tons of paper is l0-15kg.

(Three, inter-layer spray used)
Take a right amount of starch dissolved in water, and then add the starch strengthening agent and stir evenly.Sprayed it in the middle of paper with certain pressure, the amount of tons of paper is 6-10KG.

Product performance, attention

This product was added in surface sizing starch liquid, can reduce the amount of starch by replace starch and improve the ring crush strength of paper, the general increase from 20% to 30%, to meet, the requirement of users to improve ring crush strength or paper. Make the quality of corrugated paper or paperboard raise a level. Reduce the comprehensive cost 15 20 yuan per ton of paper. In the course of use it,, the starch strengthening agent should be added appropriately, and be mixed uniformly dispersed.
