Yintoni i-gypsum-based self-leveling mortar?
I-Gypsum-based self-leveling luhlobo olutsha lwezinto zokulinganisa umhlaba eziluhlaza, ezihambelana nokusingqongileyo kunye nobuchwepheshe obuphezulu. Ngokusebenzisa ukuhamba kakuhle kwe-gypsum-based self-leveling mortar, indawo enkulu yomhlaba ocolekileyo unokwakheka ngexesha elifutshane. Ineenzuzo zokuthe tyaba okuphezulu, intuthuzelo elungileyo, ukugquma ukufuma, ukuxhathisa kokungunda, ukuxhathisa kwezinambuzane, njl., kwaye kulula ukuyakheka kwaye ikhawuleze ukuphila. Ikulungele ukulinganisa imigangatho ngaphakathi endlwini, njengokumisa iicushion zokubeka iikhaphethi, imigangatho, kunye neethayile zomgangatho kwiihotele, kumagumbi eofisi zorhwebo, kunye nokuhombisa ikhaya.
Izinto eziphambili ze-gypsum-based self-leveling mortar zezi zilandelayo:
1. Izinto zeCementitious: Izinto zesamente ze-gypsum-based self-leveling mortar yi-gypsum yokwakha ekumgangatho ophezulu. Izinto eziluhlaza zokuvelisa i-gypsum yokwakha ubukhulu becala i-gypsum yendalo equlethe i-calcium sulfate okanye i-industrial by-product gypsum emva kokunyangwa kwangaphambili kunye nokucoca, kunye ne-powder yokwakha ye-gypsum ehambelana nomgangatho wesizwe ifunyenwe ngokubala kwiqondo lokushisa elifanelekileyo.
I-2.I-admixtures esebenzayo: I-fly ash, i-slag powder, njl. Injongo kukuphucula ukuhlelwa kwezinto eziphathekayo kunye nokuphucula ukusebenza kwezinto ezinzima. I-admixture esebenzayo kunye ne-cementitious material inokuphucula ukudibanisa kunye nokuqina kamva kwesakhiwo sezinto eziphathekayo ngokuphendula kwe-hydration.
3. I-Retarder: Ixesha lokumisela yisalathiso esibalulekileyo sokusebenza kwezinto zokuzilinganisa. Ixesha elifutshane kakhulu okanye elide kakhulu alihambisani nokwakhiwa. I-retarder ivuselela umsebenzi we-gypsum, ilungelelanisa isantya se-crystallization ye-supersaturated ye-dihydrate gypsum, kwaye igcina ukusetwa kunye nexesha elinzima lezinto zokuzilinganisa kwibala elifanelekileyo.
4. I-arhente yokunciphisa amanzi: Ukuze kuphuculwe ukudibanisa kunye namandla ezinto zokuzilinganisa, kuyimfuneko ukunciphisa umlinganiselo wokubopha amanzi. Ngaphantsi kwemeko yokugcina i-fluidity efanelekileyo yezinto zokuzilinganisa, kuyimfuneko yokongeza ii-agent zokunciphisa amanzi. Abanciphisi bamanzi abahambelana ne-gypsums yokwakha ezahlukeneyo bangasetyenziselwa ukwenza ukutyibilika phakathi kwezinto eziphathekayo kulula, ngaloo ndlela kuncitshiswe inani lokuxuba amanzi afunekayo kunye nokuphucula isakhiwo sezinto ezilukhuni.
5. I-arhente yokugcina amanzi: Izinto zokuzilinganisa zakhiwe kwisiseko somhlaba, kwaye ubukhulu bokwakha buncinci, kwaye amanzi athatyathwa ngokulula kwisiseko somhlaba, okubangela ukungonelanga kwe-hydration yezinto eziphathekayo, ukuqhekeka phezu komhlaba, kwaye amandla ancitshisiweyo. Ngokuqhelekileyo, i-low-viscosity (ngaphantsi kwe-1000) i-cellulose ether (HPMC) isetyenziswa njenge-arhente yokugcina amanzi. I-ether ye-cellulose ine-wettability efanelekileyo, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu, ukwenzela ukuba izinto ezizilungeleyo zingaphumi igazi kwaye zizaliswe ngokupheleleyo.
6. I-agent ye-defoaming: I-agent ye-defoaming inokuphucula ukusebenza okubonakalayo kwezinto ezizimeleyo, ukunciphisa ama-bubbles emoyeni xa izinto zenziwe, kwaye zibe nefuthe elithile ekuphuculeni amandla ezinto eziphathekayo.
