Why putty powder with glue plus bentonite after putty become bean curd residue?
Putty powder now do not add glue, you add glue and bentonite, this putty on the reaction, and certainly acid-base contrary.Such putty does not suggest that you use, because the rubber class after the reaction has solidified, lost the ability to reinforce.
Recommendation: select the amount of blue absorption 40g/100g (according to GB/T20973--2007 test); bentonite value of 95ml above the white bentonite in operation. The bentonite is thoroughly hydrolyzed and then added with glue. OK!
Montmorillonite content of bentonite is low, the glue inside the polyacrylamide flocculation bean dregs as result = =! Acid-base reaction!
