I. Product physical and chemical indicators
Appearance: light green powder; solid content: 98%; iconicity: cation; water-solubility: soluble in cold water; PH value: 2-5; can not only reduce the dosage of starch but also replace the surface sizing and water repellent agent.
II. Brief introduction of the function of solid surface sizing agent:
This product is mainly used for the production of corrugating medium and is the important additive for it; its dosage is small and strength-increasing effect is obvious, and it can increase ring crush compression resistance, tension strength and water-resistant effect of corrugating medium.
III. Technological conditions of solid surface sizing agent:
1. Adding amount: it is recommended to replace 1/3 or 1/4 of starch as per amount of starch used in surface sizing agent; generally, the proposed dosage is 15-20kg for every ton of paper, or according to the specific production conditions.
2. Adding location: starch gelatinization tank, and gelatinize together with starch.
3. Adding method: add water into the gelatinization tank, and then begin to stir. Weigh a certain amount of strengthening agent and add it into the tank together with starch and viscosity reducer. As per normal technological operation of gelatinization, properly increase or reduce the dosage of viscosity reducer by about 30% depending on glue solution viscosity.
4. Adding sequence: water→starch→stgrengthening agent→viscosity reducer→heat up to 93-95 degrees→heat preservation for 20 minutes→place them on the device (consider adding or not adding the surface sizing agent according to water-resistant requirement)
IV. Operational performance of solid surface sizing agent:
This product is added to surface sizing starch liquid and can replace the starch and thus reduce the dosage of starch. Generally, after adding this product, the ring crush compression resistance of paper products can be improved by about 20-30%, which can meet the customer’s requirements. Use of this product can make the quality of corrugating medium or paperboard be improved by one level. The cost of every ton of finished paper is reduced by 15-20yuan, and there is no need to add surface sizing agent, which also reduces the cost of sizing agent, so the comprehensive cost is reduced by 30-45yuan per ton of paper.
V. Precautions:
During use, ring crush strengthening agent shall be added appropriately, or according to the user’s water-resistant requirement. Generally, if the water-resistant time is within two minutes, add surface sizing agent is not required, while if it is required that water-resistant time exceeds two minutes, a small amount of surface sizing agent can be added.
VI. Packaging and storage:
25kg/bag; the storage period is 12 months.
