Yini i-gypsum-based self-leveling mortar?
Ukuzilinganisa okusekelwe ku-Gypsum kuwuhlobo olusha lwezinto ezisezingeni lomhlaba eziluhlaza, ezivumelana nemvelo kanye nobuchwepheshe obuphezulu. Ngokusebenzisa ukugeleza okuhle kwe-gypsum-based self-leveling mortar, indawo enkulu yomhlabathi owenziwe kahle ingakhiwa ngesikhathi esifushane. Inezinzuzo zokucaba okuphezulu, ukunethezeka okuhle, ukuvala umswakama, ukumelana nesikhutha, ukumelana nezinambuzane, njll., futhi kulula ukwakha futhi kuyashesha ukuphila. Ilungele ukulinganisa iphansi ngaphakathi endlini, njengama-cushions okulinganisa okubeka okhaphethi, phansi, namathayili aphansi emahhotela, amagumbi ehhovisi lezentengiselwano, kanye nokuhlobisa ikhaya.
Izinto eziyinhloko ze-gypsum-based self-leveling mortar yilezi ezilandelayo:
1.Impahla kasimende: Impahla kasimende ye-gypsum-based self-leveling mortar iyi-gypsum yokwakha yekhwalithi ephezulu. Izinto ezisetshenziswayo zokukhiqiza i-gypsum yokwakha ngokuyinhloko i-gypsum yemvelo equkethe i-calcium sulfate noma i-gypsum yomkhiqizo wezimboni ngemva kokwelashwa nokuhlanza, futhi impushana ye-gypsum yokwakha ehlangabezana nendinganiso kazwelonke itholakala ngokubala ezingeni lokushisa elifanele lenqubo.
2.Izingxube ezisebenzayo: Umlotha wokundiza, impushana ye-slag, njll. ingasetshenziswa njengezixube ezisebenzayo zezinto zokuzilinganisa. Inhloso ukuthuthukisa ukuhlukaniswa kwezinhlayiyana zezinto kanye nokwenza ngcono ukusebenza kwento eqinile. I-admixture esebenzayo kanye ne-cementitious material ingathuthukisa ukubumbana namandla kamuva esakhiwo sezinto ngokusebenzisa ukusabela kwe-hydration.
3. Iretarder: Isikhathi sokusetha siyinkomba yokusebenza ebalulekile yezinto ezikwazi ukuzilinganisa. Isikhathi esifushane kakhulu noma eside kakhulu asihambisani nokwakhiwa. I-retarder ivuselela umsebenzi we-gypsum, ilungisa isivinini se-crystallization ye-supersaturated ye-dihydrate gypsum, futhi igcina ukulungiselelwa nesikhathi sokuqina sezinto zokuzilinganisa kububanzi obunengqondo.
4. I-ejenti yokunciphisa amanzi: Ukuze uthuthukise ukubumbana namandla ezinto zokuzilinganisa, kuyadingeka ukunciphisa isilinganiso se-water-binder. Ngaphansi kwesimo sokugcina i-fluidity enhle yezinto zokuzilinganisa, kuyadingeka ukwengeza ama-agent okunciphisa amanzi. Izinciphisi zamanzi ezihambisana nama-gypsum wokwakha ahlukene zingasetshenziswa ukwenza ukushelela phakathi kwezinhlayiya zezinto ezibonakalayo kube lula, ngaleyo ndlela kuncishiswe inani lokuxuba amanzi adingekayo futhi kuthuthukiswe ukwakheka kwezinto eziqinile.
5. I-ejenti yokugcina amanzi: Izinto zokuzilinganisa zakhiwa phansi, futhi ubukhulu bokwakha buncane kakhulu, futhi amanzi amuncwa kalula yisisekelo esiphansi, okuholela ekungeneni kwe-hydration okwanele, ukuqhekeka phezulu, futhi amandla ancishisiwe. Ngokuvamile, i-low-viscosity (ngaphansi kuka-1000) i-cellulose ether (HPMC) isetshenziswa njenge-ejenti egcina amanzi. I-Cellulose ether inokumanzisa okuhle, ukugcinwa kwamanzi kanye nezakhiwo zefilimu, ukuze izinto zokuzilinganisa zingaphumi futhi zigcwaliswe ngokuphelele.
6. I-ejenti yokukhipha amagwebu: I-ejenti yokukhipha amagwebu ingathuthukisa ukusebenza okusobala kwezinto ezizilinganisa, inciphise amabhamuza omoya lapho izinto kwakhiwa, futhi ibe nomthelela othile ekuthuthukiseni amandla ento.
