    3, customer requirements: first glue powder according to glue powder: water = 6:100 into a solution, and then use DF-876 to adjust the pH of the solution to 8. After adding antifoaming agent: 1. The glue can not be layered; 2. Can not affect the transparency of the glue; 3. Can not react with the glue, can not have odor; 4. The defoaming effect is better, the cost is lower. The acceptable price is 16 to 19 yuan / kg. .


    Defoaming principle and analysis

    1. Analysis of the cause of foaming:

    When the glue powder stirs a certain concentration of the glue powder solution at a certain temperature with a certain stirring strength, the glue powder will generate foam.

    2. Hazard of foaming:

    Will reduce the efficacy of the glue.

    Pinholes may occur in the later stages.


    3. Glue powder defoaming method

    The glue powder defoamer is directly added to the foaming system, and it needs to be stirred evenly before use. The recommended dosage is 0.1%~0.8%, and the final dosage is based on actual experiment.
