Ngwa nke Redisperssible polymer ntụ ntụ na sistemụ ngwa agha

Na-akụ polmer polymer na ndị ọzọ inorganic ndị ọzọ (dịka ciment, gypsumypyyl, wdgsypyl, wdg) na-agwakọta ngwa ngwa iji mee ngwa agha. Mgbe agwakọtara ngwa agha a kpọrọ nkụ na mmiri, n'okpuru ihe eji eme ihe nchebe hydrophilic na igwe eji eme ihe, ngụkọta mmiri ga-agbasa n'ime mmiri.

N'ihi ihe dị iche na mgbanwe nke ọ bụla na-eme ngwụcha ngwụcha ngwụcha nke ọ bụla, mmetụta a dịkwa iche, ụfọdụ nwere mmetụta nke ịkwalite okporo mmiri, ebe ụfọdụ nwere mmetụta nke ịba ụba ThixOtropy.

N'etiti ha, ihe a na-ahụkarị bụ na ntụ ntụ polymerble na-emegharị emegharị na-abawanye ikuku, na-ebulikwa ihe owuwu nke polymer ntụ, na-achụsasị ihe owuwu a na-achụsasị, na mmiri.
