Formula of the Glue Powder GZ-101

For paperboard lamination on laminators

1. Water 55kgs

2. Put glue powder 25kgs into the above water and churn the glue up to make it even (Use whole bag of the glue powder at a time).

3. dissolve 2-2.3kg (summer: 2kg, and winter: 2.3kg) caustic soda together with 1-1.2kg borax into another 10kg water and mix round the solutions for about 5-10 minutes; then pour this hot solution into the glue in step 2, and mix them evenly.

To make the glue, the quantity of the caustic soda should be added or reduced as per its quality.

4. In case of much foam, pls add around 30ml tributyl phosphate into the above glue got finally in term 3 and mix it around evenly; and now the glue is completed finally and can be used in laminators.

Remark:

1. Caustic soda: the effect of the caustic soda is as cataplasm. If deficiency, the glue looks to be very thick, bad viscidity and fluidity; meanwhile, it will be coagulated a little long time later. But in case of excess, the glue will be badly affected; so just add it as per this recipe. The purity of the caustic soda must be over 96%.

2. The function of the borax (purity over 95%): to improve the viscosity of the glue.

3. The action of the tributyl phosphate: antifoaming agent. More foam, more of it can be used; but the excessive can reduce the viscosity.

4. The features of the glue: drying fast, bonding fastness, less quantity and cost. In case the glue be left unused for a long time, it can be used continuously just churning it up before using.

5. Place the finished glue aside about 15mins before use. What’s more, the color is canary.

6. Water glue applying quantity: cardboard to cardboard lamination: about 40gram per m2; cardboard to corrugated board lamination: about 20-40gram per m2.

7. Before using the glue, it should be churned up evenly.

8. With this recipe, one ton of the glue powder can be made into 3.74 tons of the glue.
