water glue making formula:
- Water 55kgs
- 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, stirring for 5-10minutes).
- 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 (stirring for 10minutes).
To make the glue, the quantity of the caustic soda should be added or reduced as per its quality.
Remark:
- 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%.
- The function of the borax (purity over 95%): to improve the viscosity of the glue.
- The action of the tributyl phosphate: antifoaming agent. More foam, more of it can be used; but the excessive can reduce the viscosity.
- 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.
- Place the finished glue aside about 15mins before use. What's more, the color is canary.
- Water glue applying quantity: cardboard to cardboard lamination: about 40gram per m2; cardboard to corrugated board lamination: about 20-40gram per m2.
- Before using the glue, it should be churned up evenly.
- With this recipe, one ton of the glue powder can be made into 3.74 tons of the glue.

Water glue notice
- During water glue making, the mixer speed should be 60-70rpm.
- Water glue quantity to be applied onto flute board is about 25gram per square meter.
- We suggest that customers just make water glue for the same day use, and avoid to keep the water glue for next day or next few days.
- Water glue storage: lamination water glue can be kept for 7 days in summer and 10 days in winter. After some time storge, the lamination water glue will become layers, just stir it evenly before using.
- After the laminated paperboards come out from the laminating machine, pls pile them together, and put a heavy plate on the pile to keep the paperboard flat.
- The laminated paperboard may be sticked well in 30 minutes, and it can be moved to next process such as die cutting, etc. in 1-2hrs, and it can be dry entirely in 1-2 days.
