6.Compared with random copolyethers,the wetting ability,emulsifying power,foam disappearing rate and solidifying temperature of block copolyethers BPE with PO block connecting to butoxyl group increase respectively by 30 times,1 time,4 times and 36 ℃,meanwhile the cloud point,surface tension,foaming ability and heat stability decrease by 32 5 ℃,8 2 mN/m,1 5 times and 55% respectively.
9.Higher CO2 pressure would speed delivery—but produce a river of foam.
10.A foam formed by soap or detergent agitated in water, as in washing or shaving.
