Ngwa ngwa mmiri na-ezo aka na simenti nke nwere ezigbo ihe mgbochi mmiri na enweghị ike ime ka o sie ike site n'ịgbanwe nha ngwa agha na iji usoro ihe owuwu a kapịrị ọnụ. Ngwa agha mmiri na-adịghị mma nwere ezigbo nguzogide ihu igwe, ịdịte aka, enweghị ike, kọmpat na nrapado dị oke elu yana mmetụta mgbochi mmiri siri ike na mgbochi corrosion. Ngwa nke ntụ ntụ polymer redispersible dị ka isi ihe mgbakwunye na ngwa agha anaghị egbochi mmiri emewo ka arụmọrụ ngwa ngwa anaghị egbochi mmiri dịkwuo mma, na-eme ka ọ bụrụ otu n'ime ihe ndị dị mkpa na ọrụ owuwu.
Ngwa ntụ ntụ a na-emegharị emegharị na ngwa agha anaghị egbochi mmiri na-egosipụtakarị n'akụkụ ndị a:
Mmiri na-egbochi mmiri na mgbochi-seepage: The redispersible ntụ ntụ nwere ike mejupụta pores na ngwa agha, na-akpụ a ok waterproof oyi akwa na ngwa agha, na-egbochi mmiri ịbanye na imeziwanye waterproof arụmọrụ nke dum ngwa agha oyi akwa.
Ike njikọta siri ike: ntụ ntụ polymer na-agbanwe agbanwe nwere ike ime ka njikọ na nchikota dị n'etiti ngwa agha na oyi akwa isi, na-eme ka oyi akwa mmiri na-adịghị sie ike ma ghara ịdaba.
Nguzogide na-ekpo ọkụ: polymer ntụ ntụ redispersible nwere ike inye aka melite nkwụsị nke ngwa agha, na-eme ka ọ dị mma maka ọnọdụ ihu igwe dị iche iche; ntụ ntụ polymer redispersible nwere ike imeziwanye ike nkwụsị nke ngwa agha, na-eme ka ngwa agha ahụ dịkwuo ogologo. Site n'ịbawanye njikọ dị n'ime na viscosity nke ngwa agha ahụ, a na-eme ka ike zuru ezu nke ngwa agha dịkwuo mma.
Ewu mma: Redispersible polymer ntụ ntụ nwere ike na-emekarị ngwa ngwa gbazee na mmiri oyi ma nwee ike melite usoro arụmọrụ nke ciment ngwa agha, nke na-enyere aka mma ịchịkwa na-ewu usoro nke ngwa agha na-mma na-ewu arụmọrụ.
Mmetụta nke ntụ ntụ polima a na-emegharị emegharị na ngwa agha mgbochi mmiri ọhụrụ:
A, melite arụmọrụ;
B, Mgbakwunye mmiri na-ejigide, mma ciment hydration;
Mmetụta na hardening waterproof ngwa agha:
A, Belata modul na-agbanwe nke ngwa agha ma welie ya dabara adaba na isi oyi akwa;
B, Mmụba mgbanwe na iguzogide mgbawa;
C, Melite njupụta ngwa agha;
D, Hydrophobicity;
E, welie adhesion.
