Preparation and Application of Adhesive in Food Bag Production

For different applications, different proportions of silica and soda can also be added according to the use requirements. For example, the formula of glue is asbestos cement: 2.268kg aluminum oxide: 0.226 sodium silicate 3.785L. The new formula is: sodium silicate as adhesive, metal oxide or hydrogen oxide as curing agent, and silicon oxide or aluminum oxide as bone material, It can be cured at low temperature and heated at no temperature. Its low temperature cured products have strong water resistance. Sodium silicate binder has bonding effect due to the loss of water, and has good bonding effect on porous materials easy to absorb water, such as paper paper, paper fiber, paper metal, paper glass, etc. It is widely used in the processing of paper products and cardboard boxes.
