Ziziphi izinto ezifunekayo kwi-gypsum self-leveling mortar?
1. I-admixtures esebenzayo: Izixhobo zokuzibamba zingasebenzisa i-fly ash, i-slag powder, kunye nezinye izixube ezisebenzayo ukuphucula ukusabalalisa ubungakanani beengqungquthela kunye nokuphucula iimpawu zezinto ezilukhuni. I-powder ye-Slag idlula kwi-hydration kwindawo ye-alkaline, inyusa ukuxinana kwesakhiwo kunye namandla kamva.
2. Izinto eziphathekayo ze-cementitious zangaphambili: Ukuqinisekisa ixesha lokwakha, izinto zokuzilinganisa zineemfuno ezithile zamandla okuqala (ikakhulukazi i-24-hour flexural and compressive strength). I-samente ye-sulphoaluminate isetyenziswa njengesixhobo se-cementitious sangethuba. I-sulphoaluminate sement i-hydrates ngokukhawuleza kwaye inika amandla aphezulu aphezulu, ukuhlangabezana nezi mfuno.
3. I-activator yealkaline: imathiriyeli yesamente ehlanganisiweyo yeGypsum ifikelela kumandla awo omileyo aphakamileyo phantsi kweemeko zealkaline ephakathi. I-Quicklime kunye ne-samente ye-32.5 ingasetyenziselwa ukulungelelanisa i-pH ukudala indawo ye-alkali ye-hydration.
4. Ukusetha i-accelerator: Ixesha lokumisela liyisalathisi sokusebenza kwezixhobo zokuzilinganisa. Ukumisela ixesha elifutshane kakhulu okanye elide kakhulu kuyingozi ekwakheni. I-coagulant ivuselela umsebenzi we-gypsum, ikhawuleza i-crystallization ye-supersaturated ye-dihydrate gypsum, inciphisa ixesha lokumisela, kunye nokugcina ukusetwa kunye nexesha elinzima lezinto zokuzilinganisa ngaphakathi kwinqanaba elifanelekileyo.
5. Umnciphisi waManzi: Ukuphucula ukuxinana kunye namandla ezinto zokuzilinganisa, umlinganiselo wamanzi ukuya kwi-samente kufuneka uncitshiswe. Ngelixa ugcina i-fluidity elungileyo, ukongezwa kokunciphisa amanzi kuyimfuneko. Indlela yokunciphisa amanzi ye-naphthalene-based based reducer yamanzi kukuba amaqela e-sulfonic acid kwi-naphthalene-based based reducer molecules i-hydrogen-bond kunye ne-molecule yamanzi, eyenza ifilimu yamanzi ezinzileyo phezu kwendawo ye-cementitious material. Oku kuququzelela ukutyibilika kwezinto eziphathekayo, ukunciphisa inani lokuxuba amanzi afunekayo kunye nokuphucula isakhiwo sezinto ezinzima.
6. I-Agent yokugcinwa kwamanzi: Izixhobo zokuzilinganisa zisetyenziselwa kwisiseko esincinci esincinci, okwenza kube lula ukuxhamla kwisiseko. Oku kunokukhokelela kwi-hydration enganeleyo, ukuqhekeka kwendawo, kunye nokunciphisa amandla. Kolu vavanyo, i-methylcellulose (MC) ikhethwe njenge-arhente yokugcina amanzi. I-MC ibonisa ukumanzisa okugqwesileyo, ukugcinwa kwamanzi, kunye neempawu zokwenza ifilimu, ukuthintela ukukhutshwa kwamanzi kunye nokuqinisekisa ukuhanjiswa okupheleleyo kwezinto ezizilinganisa.
7. Umgubo wepolymer owenziwe kwakhona (emva koku ubizwa ngokuba ngumgubo wepolymer): Umgubo wepolymer unokunyusa imodyuli enwebekayo yezinto ezizilinganisayo, iphucule ukumelana nokuqhekeka kwayo, ukomelela kwebhondi, kunye nokumelana namanzi.
8. I-ejenti ye-Defoaming: I-defoaming agents inokuphucula umgangatho wezinto eziphathekayo, ukunciphisa ama-bubbles ngexesha lokubumba, kunye negalelo kumandla ezinto eziphathekayo.
