Glue preparation method
Materials : Corn starch or cassava starch(Choose one),Polymer powder,caustic soda,borax
1、The temperature should be controlled at about 25 ℃s.

2、Pouring the starch(25kg) and resin polymer powder(1.75kg) into the agitating tank , then stirring for 10 ~15 minutes.
3、Solid caustic soda (which can not be converted into liquid) should be added into the above mixed solution quickly and evenly under agitation.
4、After about three minutes, it will become solid and stop mixing.
5、Full fermentation and emulsification are required, which takes about 40 to 120 minutes .
6、The standard of full emulsification is that the foam is almost completely gone. Measuring around 18 seconds with Cup NO.4(Keep in mind that borax should not be added when the colloid flow is too thick, otherwise it will become very thick, and the viscosity is too high, causing the glue can not be used).
7、After the full emulsification is confirmed, the borax can be evenly sprayed in the agitation state. After stirring for 10 minutes, measuring the flow rate making it increase about 5-8 seconds, this is the the best using flow.

usage method:
1. The concentration of the oxidized glue is measured with the No. 4 cup at a flow rate of 25-28 seconds
2. The paper mounted at random shall be kept under pressure for a period of time, and the time shall not be less than 3-5 minutes
3. The glue quantity is determined according to the glued paper, and the glue quantity is controlled accordi0ng to different specifications of corrugated paper
