接枝共聚 降滤失剂
利用多羟基大分子PVA对磺化酚类树脂LF接枝共聚,合成一种新型的泥浆降滤失剂.其抗温210℃、抗盐NACL达36%;单一处理泥浆其效果远优于SMP-Ⅱ+SMC+SMK复配共处理体系.热%A new type of mud filtrade loss controller has been synthesized based on a graft copolymer by grafting polymer macromolecult PVA to sulphonated phenolic resin LF. This controller can resist 210℃ and NaCl 36%, and is superior to SMP Ⅱ+SMC+SMK composite system in treating mud alone.
