Gịnị bụ mmetụta nke hydroxyppropyylthylcelllose na ngwa agha ciment?

Hydroxypyl Methylcellose nwere ike ime ka mgbakwunye ciment.

Hydroxypylthyth methylcellose bụ mmiri na-agbanye mmiri. Ọ na-eme ka ngwakọta nke ngwakọta site na ịba ụba viscosity nke mmiri agwakọta. Enwere ike ịgbasa ya na mmiri iji mepụta otu ọrịa. Ọ bụ ihe ọkụkụ hydrophilic. Site na nnwale, anyị nwere ike ịchọpụta na mgbe ego nke Nafthalene-inmesi ike dị elu karịa ciment na-abawanye ga-ebelata mgbakwunye nke ngwa agha ciment nke ọma. Gịnị mere ihe ndị dị otú ahụ dị otú ahụ ga-eme? Nke a bụ n'ihi na Nafthalene-arụmọrụ dị elu nke na-agbaziwanye bụ freerant. Mgbe a na-eji mmiri a na-ewepụta mmiri n'ogwe osisi ciment, ọ ga-eme ka ọ dị n'elu osisi ciment iji mee ka ala ciment nwee otu ụgwọ. Igwe ọkụ eletrik na-eme ka ciment irighiri ihe ahụ na-eme ka ihe owuwu nke cent na-aghọọ, na mmiri kechiri ihe owuwu ahụ, nke ga-akpata mfu nke mfu ciment. N'otu oge ahụ, a chọpụtara na mmụba nke ọdịnaya nke hydyypylthylthyl methylcellose, gbasaa nke osisi ciment a gwakọtara agwakọta nke ọma ma ka mma.
