N'ime usoro mmepụta ihe ụfọdụ, onye na-emepụta ihe na-agbakwụnyekarị otu onye na-ebelata mmiri, nke nwere ike ịnọgide na-enwe slump nke ihe, melite mgbasa nke ihe irighiri ihe, ma belata oriri mmiri. Otú ọ dị, e nwere ihe ndọghachi azụ na onye na-ebelata mmiri na-ebelata mmiri bụ surfactant, nke ga-eduga na ọgbọ nke ụfụfụ, nke ga-emetụta ike na àgwà nke ihe ahụ. Ọ bụrụ na a na-emepụta ụfụfụ n'oge usoro ihe owuwu ahụ, ọ dị mkpa ka e wepụ ya n'oge. Enwere defoamer nke nwere ike ịbụ nke ukwuu Ụzọ kacha mma isi kpochapụ ụfụfụ ihe bụ mmiri ciment na-ebelata ihe ntanye defoamer.

Nrụchapụ arụrụ arụ nke mmiri ciment na-ebelata ihe defoamer:

Nkedefoamer a na-ejikarị polyether emezigharị ma bụrụ nke polyetherdefoamer. Nkedefoamer agaghị emetụta ndị dị mkpa Njirimara nke ihe na ngwa nke ihe ụfụfụ, na nwere ike kwụsiri ike defoaming na ụfụfụ suppressing mmetụta. Nkedefoamernwere ezi dispersibility na ihe ụfụfụ, na nwere ike ngwa ngwa gbasasịa n'ime ihe ụfụfụ iji nweta ikpeazụ ụfụfụ na-agbaji na defoaming mmetụta. Na mgbakwunye na de-foaming na mgbochi ụfụfụ na ihe ụfụfụ, ọ nwekwara ike de-ụfụfụ na elu okpomọkụ na ike acid na alkali gburugburu ebe obibi.

Mmetụta na-emebi ụfụfụ nke onye na-ebelata mmiri cimentdefoamer:

Mmetụta nkedefoamer na arụmọrụ nke ihe bụ tumadi pụtara abụọ akụkụ: n'otu aka ahụ, ọ pụrụ ikpochapụ ikuku egosipụta n'etiti ihe na formwork ruo n'ókè ụfọdụ, n'ụzọ dị irè gbochie ma ọ bụ kpochapụ ọgbọ nke mmanụ aṅụ na pockmarked na-ebupụta na ihe elu, na-eme ka elu nke ihe nwere High flatness na gloss. N'aka nke ọzọ, ndịdefoamer nwere ike iwepụ nnukwu ikuku ikuku na ihe ahụ, belata ikuku ikuku na porosity dị n'ime nke ihe ahụ, ma melite ihe ndị na-emepụta ihe na ịdịte aka nke ihe ahụ.

Otu esi eji ihe na-ebelata mmiri cimentdefoamer:

1. Mgbedefoamer na-eji na mmepụta nke ihe ụfụfụ na mmiri na-ebelata gị n'ụlọnga, ihe ụfụfụ slurry ga-dịtụ nnyapade. A na-atụ aro ka ịgbakwunye yadefoamer ngwa ngwa mgbe a na-emepụta ụfụfụ ahụ, nke nwere ike iwepụ ngwa ngwa na-enweghị isi na nnukwu ụfụfụ na-emepụta ihe na-emepụta otu obere ikuku ikuku nwere ike ime ka ike sie ike.

2. Nkedefoamer nwere dispersibility siri ike ma dị mfe ikewapụ mgbe etinyere ya ogologo oge. A na-atụ aro ka a na-eme ngwakọta na-aga n'ihu n'oge mwepụ nke ụfụfụ ihe.

3. Nkedefoamer nwere ike mebie ya n'ihi alkalinity ya, yabụ zere iji ya mgbe uru pH karịrị 10.
