Solid surface sizing agent Product physical and chemical index: Appearance: light green powder Solid content: *8% Ionicity: cationic Solubility: soluble in cold water PH value: **5 Can reduce starch dosage and replace liquid surface sizing agent Brief introduction of product function: The product is widely used in corrugated base paper, packaging paper and other aspects, small dosage, significant improved effects, can improve ring crush strength, tensile strength and water resistance effects of corrugated paper, which is important auxiliary agent of corrugated base paper. Currently, many manufacturer adopt method of add lots starch, be surface sizing to improve ring crush strength, however, due to the soaring price of starch, larger dosage, result in higher cost with limited increase range of ring crush strength, which make increased production cost and reduced profits. Our solid surface sizing agent is widely used by many papermaking companies, and can replace starch when adding, and more significant effect of improve ring crush strength than starch. Solid sizing agent is mainly used for increase strength of cardboard, increase physical index, such as paper strong hardness, bursting strength, ring crush strength and tension. 1. 2. Can make corrugated paper ring crush strength increase by ****0% ( enhance 1.**2 ring crush index). Increase water resistance of corrugated paper, can reach water resistance effects of **5 minutes without add surface sizing agent. Technology conditions: 1.

Dosage: according to starch dosage used for surface sizing, suggest to replace 1/3 or 1/4 starch, generally suggested add **7kg/ton paper, also can be used based on specific production conditions. Join location: starch gelatinized tank, gelatinized with starch. Also can add solid sizing agent to gelatinized starch solution. Join method: join water to gelatinized tank, then start stirring. Weigh a certain amount starch and viscosity reducer together join to gelatinized tank. Operating as normal gelatinized process, after heated to *5℃, add solid agent, continue stirring for *0 minutes, then keep warm for backup. Can appropriately increase viscosity reducer dosage about *0% according to solution viscosity. Join order: water-starch-viscosity reducer-heat to ****3℃-add solid agent-keep warm for *0minutes-onto machine (add or not add surface sizing agent based on water resistance requirements).

Product usage property Solid sizing agent add in surface sizing starch solution, can replace starch, reduce starch dosage. 1. Improve paper ring crush strength after adding the product, generally, the increased range is ****0%, which can meet user requirements to increase ring crush strength. Improve one grade of corrugated paper or cardboard quality.2. 3. Reduce ****0RMB cost per ton finished paper. reduce sizing agent cost. Therefore, the overall cost is reduced ****0RMB/ton paper. Note: Solid surface sizing agent must be suitable added during using process which can be according to user water resistance requirement. 1) 2) Generally, can not add surface sizing agent when water resistance time is about 2 minutes. When water resistance time is more than 2 minutes, can add a small amount of surface sizing agent. Packaging & Storage: *5kg/bag. Shelf life is *2 months.
