10月底,中建商品混凝土有限公司发明专利《一种用于聚羧酸减水剂的防腐剂》获得国家授权。据悉,该发明专利于2012年提出申请,历时两年获得授权,发明内容涉及一种用于聚羧酸减水剂的防腐剂,可以有效地防止聚羧酸减水剂发霉变质,延长聚羧酸减水剂的保质期至8个月甚至1年,解决了聚羧酸减水剂储存难题。由于受霉菌、细菌的侵袭,聚羧酸减水剂在贮存的过程中容易变质发臭,在气温高时尤其严重,变质的减水剂颜色
At the end of October, the invention patent of CCC Commodity Concrete Co., Ltd., a preservative for polycarboxylate water-reducing agent, obtained the national authorization. It is reported that the invention patent application in 2012, which lasted two years was authorized, the invention relates to a polycarboxylate superplasticizer preservative can effectively prevent the polycarboxylate superplasticizer moldy, extended polycarboxylate Acid water-reducing agent shelf life of 8 months or 1 year, to solve the polycarboxylate superplasticizer storage problems. Due to mold, bacteria invasion, polycarboxylate superplasticizer in the storage process is easy to degenerate smelly, especially when the temperature is high, the deterioration of water-based color
