Surface Sizing Agents

Physical property of Surface Sizing Agents:
1.Product type : styrene-acrylate high polymer
2.Physical appearance : light gray with blue latex
3.Dynamic viscosity : 50mPa.s
4.Solid content : 30% 2%
5.PH value : 2.5-5.5
6.Ionicity: Cation
7.Storage period : 3 Month(5-35AcA A )

Product feature :
1. It can completely or partly replace internal sizing agent,clean paper making environment,reduce the production cost.
2. It can greatly reduce the paper powder production,improve the printing adaptability and
surface strength.
3. Excellent mechanical stability.It can be used in a variety of different types of sizing machine.

Applicable scope :
High strength corrugated paper, cardboard paper, cultural paper, coated laundry board, white cardboard, copper plate paper and so on.
Usage and attention :
1. Gelatinization of starch is diluted to 8%-10%. Compared to starch,add 3%-5% of Aluminum sulfate,3%-5% of surface sizing agent solution. If not used with starch,the dosage compared to coating liquid is 0.5%-1.5% (dry solid content)
2. It can be added to the starch liquid sizing pump inlet by metering pump.In the sizing tank,the agent can play better sizing effect at the temperature of 60-65A A .
3. In the sizing process,it should be that at least a dryer temperature is above 95AcA A . The paper roll have 100% degree of sizing after completed.
