Redispersible polymer powder (RDP) bụ ntụ ntụ na-acha ọcha nke na-agbaze ngwa ngwa na mmiri.A na-eme ya nke emulsion polymer sprayed site na usoro pụrụ iche.A na-eji RDP eme ihe n'ọtụtụ ebe na-ewu ụlọ n'ihi na ọ na-arụ ọrụ nke ọma, nke nwere ike imeziwanye arụmọrụ nke ihe cimenti.Na post a, anyị ga-atụle ike RDP maka ịkwalite Mortar.
Ọrụ nke RDP
1. Mma n'ibu Njirimara
RDP nwere ike ịkwalite ihe eji arụ ọrụ nke ihe simenti, gụnyere ike mkpakọ, ike mgbanwe na ike ntanye.Nke a bụ n'ihi na mgbe RDP na-ejikọta ya na ciment, ọ nwere ike ịmepụta usoro dị oke na nke siri ike, nke nwere ike ime ka adhesion dị n'etiti ihe ndị dị na ya ma belata porosity nke ihe.Ya mere, ọ nwere ike melite n'ibu Njirimara nke ihe.
2. Mee ka njikọta ọnụ
Njikọ dị n'etiti ihe ngwa ngwa nwere njikọ chiri anya na viscosity ya.Nke dị elu nke viscosity, nke dị elu na njikọ dị n'etiti ụmụ irighiri ihe.Nke a dị mkpa karịsịa na ngwa agha masonry dị ka ọ na-eme ka ngwa ngwa ahụ ghara ịda mbà ma ọ bụ na-asọba n'oge a na-ewu ya.RDP nwere ike ịbawanye viscosity nke ngwa agha ahụ nke ukwuu, si otú ahụ na-amụba ike jikọrọ ọnụ n'etiti ihe ndị ahụ ma hụ na ịdị mma nke ọrụ masonry.
3. Meziwanye njigide mmiri
Njide mmiri bụ ihe dị mkpa nke ngwa agha.A kọwapụtara ya dị ka ike ihe onwunwe iji jide mmiri n'ime matriks ya.Ọ bụrụ na njide mmiri ezughị oke, ngwa agha na-akpọnwụ ngwa ngwa, nke ga-emetụta ọrụ ya ma belata ike ya.RDP nwere ike melite njigide mmiri nke ngwa agha, gbochie ya ịsa ngwa ngwa, ma hụ na arụ ọrụ dị mma.
4. Mee ka ọrụ rụọ ọrụ
Ịrụ ọrụ na-ezo aka n'ikike nke ngwa agha na-adị mfe ịrụ na ịmepụta.Arụ ọrụ nke ngwa agha nwere njikọ chiri anya na nkwụsi ike ya, viscosity na arụmọrụ njide mmiri.RDP nwere ike ime ka ngwa ngwa rụọ ọrụ nke ọma site n'ịbawanye nkwụsi ike ya na viscosity ya.Ọ nwekwara ike inye ezigbo njide mmiri, nke nwere ike hụ na arụ ọrụ nke ngwa agha na-arụ ọrụ ogologo oge.
5. Belata mgbawa
Ịgbawa bụ nsogbu a na-ahụkarị na ihe ndị sitere na ciment.A na-akpata ya site n'ọtụtụ ihe, dị ka ọnụ ọgụgụ nkwụsị nke ihe onwunwe, usoro eji eme ihe, ọnọdụ gburugburu ebe obibi, wdg RDP nwere ike ibelata ihe ize ndụ nke mgbawa site n'ịbawanye mgbanwe nke ihe na ductility.Ọ nwekwara ike inye ezigbo adhesion n'etiti ụmụ irighiri ihe, nke nwere ike ibelata nchikota nke nrụgide na ihe ma gbochie mgbawa.
6. Ọganihu ka mma
Ịdị ogologo oge na-ezo aka n'ikike nke ihe iji guzogide mmebi nke ihe kemịkalụ, anụ ahụ na gburugburu ebe obibi kpatara.RDP nwere ike imeziwanye ịdịte aka nke ngwa agha site n'ịkwalite iguzogide mmiri, mgbanwe okpomọkụ na ihu igwe.Ọ nwekwara ike inye ezigbo adhesion n'etiti ụmụ irighiri ihe ma mee ka ihe nkiri na-emepụta ihe nkiri nke ngwa agha, nke nwere ike imeziwanye ikike ya iguzogide mbuze na iyi.
na ngwụcha
N'ịchịkọta, mmetụta RDP na-emeziwanye ngwa agha dị ịrịba ama.Ọ nwere ike ịkwalite ihe ndị na-emepụta ihe, na-amụba njikọta, melite njide mmiri, kwalite ịrụ ọrụ, belata mgbawa, ma melite ogologo oge.Ngwongwo ndị a dị oke mkpa iji hụ na ịdị mma nke ọrụ masonry na ịrụ ọrụ ogologo oge nke ụlọ.Ya mere, a na-eji RDP eme ihe n'ọtụtụ ebe n'ọhịa nke owuwu ma ghọọ ihe mgbakwunye dị mkpa iji melite arụmọrụ nke ngwa agha.
