Zusammenfassung: | The invention relates to the glue emulsion testing field, in particular to a method for testing the foaming rate of an adhesive emulsion. The method includes the steps of: firstly preparing a 500ml glue emulsion, conducting weighing to obtain a volume A and a weight B; putting the glue emulsion into a stirring mechanism to conduct stirring for 5min; stopping stirring, then pouring the glue emulsion into a measuring cylinder immediately, 30sec later, reading the glue emulsion volume C in the measuring cylinder and weighing the glue emulsion weight D; calculating a foaming rate according to a formula of: foaming rate=(C-A*D/B)/(A*D/B); testing the glue emulsion repeatedly through the steps 1-4 and recording the results, taking the average value of all the results, and finally conducting contrast design of a glue emulsion qualified standard value with the average value, and judging whether the glue emulsion is qualified. The method has a simple and clever process, tests the foaming rate of the glue emulsion to j |
