Yiziphi izimfuneko zezinto ezibonakalayo ze-gypsum self-leveling mortar?
1. Ama-admixtures asebenzayo: Izinto zokuzilinganisa zingasebenzisa umlotha wempukane, i-slag powder, nezinye izixube ezisebenzayo ukuze kuthuthukiswe ukusabalalisa usayizi wezinhlayiyana futhi kuthuthukise izakhiwo zezinto eziqinile. Impushana ye-slag ithola amanzi endaweni ene-alkali, ikhulisa ukuminyana kwesakhiwo namandla kamuva.
2. Izinto zikasimende zamandla okuqala: Ukuqinisekisa isikhathi sokwakha, izinto zokuzilinganisa zinezidingo ezithile zamandla angaphambi kwesikhathi (ikakhulukazi amahora angu-24 aguquguqukayo namandla okucindezela). Usimende we-Sulphoaluminate usetshenziswa njenge-cementitious material yokuqala-amandla. I-sulphoaluminate usimende i-hydrates ngokushesha futhi inikeza amandla aphezulu okuqala, ukuhlangabezana nalezi zidingo.
3. I-activator ye-alkaline: Izinto zikasimende eziyinhlanganisela ye-Gypsum zithola amandla azo omile aphezulu kakhulu ngaphansi kwezimo ezine-alkali emaphakathi. I-Quicklime kanye nosimende ongu-32.5 kungasetshenziswa ukulungisa i-pH ukuze kwakhiwe indawo ene-alkali ukuze kufakwe amanzi.
4. Ukusetha i-accelerator: Isikhathi sokusetha siyinkomba yokusebenza eyinhloko yezinto ezizilinganisa ngokwazo. Ukubeka isikhathi esifushane kakhulu noma eside kakhulu kuyingozi ekwakheni. I-coagulant ivuselela umsebenzi we-gypsum, isheshisa i-crystallization ye-supersaturated ye-dihydrate gypsum, ifinyeze isikhathi sokusetha, futhi igcine ukusetha nesikhathi sokuqina sezinto ezizilinganisa ngaphakathi kwebanga elifanele.
5. Isinciphisi samanzi: Ukuthuthukisa ukuminyana namandla ezinto ezizilinganisa, isilinganiso samanzi ukuya kusimende kufanele sincishiswe. Ngenkathi kugcinwa uketshezi oluhle, ukungezwa kwesinciphisi samanzi kuyadingeka. Indlela yokunciphisa amanzi yokunciphisa amanzi esekelwe ku-naphthalene iwukuthi amaqembu e-sulfonic acid ku-molecule yamanzi asekelwe ku-naphthalene i-hydrogen-bond nama-molecule amanzi, enza ifilimu yamanzi ezinzile ebusweni be-cementitious material. Lokhu kusiza ukushelela kwezinhlayiya zezinto ezibonakalayo, ukunciphisa inani lokuxuba amanzi adingekayo futhi kuthuthukise ukwakheka kwezinto eziqinile.
6. I-ejenti Yokugcina Amanzi: Izinto zokuzilinganisa zisetshenziswa kungqimba oluyisisekelo oluncane, okwenza lumuncwe kalula ungqimba oluyisisekelo. Lokhu kungaholela ekungeneni kwamanzi okwanele, ukuqhekeka kwendawo, nokuncipha kwamandla. Kulokhu kuhlolwa, i-methylcellulose (MC) ikhethwe njenge-ejenti egcina amanzi. I-MC ikhombisa ukumanzisa okuhle kakhulu, ukugcinwa kwamanzi, kanye nezakhiwo zokwakha ifilimu, ukuvimbela ukuphuma kwamanzi nokuqinisekisa ukugeleza okugcwele kwezinto ezizilinganisa.
7. I-polymer powder ehlakazeka kabusha (ngemuva kwalokhu ebizwa ngokuthi i-polymer powder): I-polymer powder ingakhuphula i-elastic modulus yezinto ezizilinganisa, ithuthukise ukumelana kwayo nokuqhekeka, amandla ebhondi, nokumelana namanzi.
8. I-ejenti yokukhipha amagwebu: Ama-Defoaming agents angathuthukisa izakhiwo ezingaphezulu kwezinto ezizilinganisa, anciphise ama-bubbles ngesikhathi sokubumba, futhi afake isandla emandleni ezinto ezibonakalayo.
