高稳定性污泥蛋白发泡剂的发泡特性及应用研究
Research on foaming characteristics and application of foaming agent of high stability sludge protein
摘要
Abstract
Sample of sludge protern was made into high stability of sludge protein foaming agent by adding different amounts of foam stability GP-1. The results shows that 10 mL sludge protein,90 mL water and 0. 4 g GP-1 mixed together,the initial volume of foam approached to 770 mL,foam seeping time was more than 15 hours,foam half-life was more than 64 h and comprehensive foaming capacity of the foam liquid was reached temperature decreased. The foam was more stable at pH 3～13. Based on the foaming characteristics and stabili-ty of sludge protein foaming agent and cement gelation time as well as cement characteristics,foam cement block was made using sludge protein foaming agent as sludge protein foam concrete foaming agent,the results show that when 0,6,6.8,7.6,8.4 and 9.2 mL of sludge protein foam concrete foaming agent was respectively mixed with 200 g of cement to make foam concrete block,the density of the foam concrete block decreased from 2. 07g/cm~3 to O. 34 g/cm~3,and the volume of the foam concrete block increased from 130 cm~3 to 755 cm~3. The foam concrete block was weighted at the 1 st d,the 7th d and the 28th d respectively in each case,the weight of foam concrete block was unchange at the 1st d and the 7th d. However,the foam concrete block lost its weight at the 28th d. The study provides a research base for the sludge protern make into foam concrete foaming agent and ap-plication of roof insulation and heat preservation.关键词
