I-hydroxypropyl methylcelluloseIsetyenziswa rhoqo kumashishini ahlukeneyo. Nangona abantu abaninzi bengakuqondi kakuhle, ichaphazela amashishini ahlukeneyo. Kwinkqubo yokwakha kumashishini okwakha, idla ngokusetyenziselwa ukwakha udonga kunye nokuhombisa i-stucco, i-Caulking kunye nezinye iindawo zokwakha oomatshini, ingakumbi kulwakhiwo lokuhombisa, idla ngokusetyenziselwa ukufaka iithayile, imabula, kunye nezinye izinto zokuhombisa zeplastiki. Inezinga eliphezulu lokunamathela kwaye inokunciphisa ubungakanani besamente esetyenziswayo. Isetyenziswa kumashishini okugquma, isetyenziswa kakhulu njenge-thickener, inokwenza umaleko ube mhle kwaye ukhanye, kube nzima ukuwususa umgubo, iphucule ukusebenza kwe-leveling, njl.njl., ingakumbi ekusetyenzisweni kwicandelo lokwakha i-self-leveling mortar.
Ibhaso lesanti elizilinganisayo ngokuyintloko yimveliso ekhethekileyo yodaka oluxutywe nolomileyo olunemisebenzi yokuzilinganisa nokuzilinganisa. Amandla ayo okuzilinganisa kunye nokuzilinganisa abaluleke kakhulu ekufezekiseni umaleko womhlaba ongenamthungo nogudileyo. Kwiimveliso ezilungileyo zokuzilinganisa, okokuqala kufuneka ibe nokusebenza okufanelekileyo, kwaye ikwazi ukugcina ukusebenza kwayo ngokubanzi kokuzilinganisa kunye nokukwazi ukuziphilisa ngaphakathi kwexesha lokwakha. Ngale ndlela, oku kufuna ukuba udaka luqinisekise ngokupheleleyo uzinzo kunye nokufana kwalo ngaphakathi kweli xesha. Okwesibini, udaka kufuneka lube namandla athile, aquka amandla okuthwala kunye namandla okubopha kumphezulu wesiseko. Ezi ziimeko ezisisiseko zokusetyenziswa okuqhelekileyo kwezinto zokuzilinganisa, kwaye ukufezekiswa kwezi mpawu zokuzilinganisa kufuna i-hydroxypropyl ukongezwa kwe-methyl cellulose ether kunokutyeba kwaye kwandise i-viscosity, kwaye ikwanazo neempawu zokugcina amanzi amaninzi kunye nokwandisa ixesha lokwakha.
Okukhona i-viscosity ye-hydroxypropyl methylcellulose iphezulu, kokukhona i-viscosity yezinto ezisekwe kwisamente eziguquliweyo ingcono, kodwa ukuba i-viscosity iphezulu kakhulu, iya kuchaphazela ukunyibilika nokusebenza kwezinto. Ukongeza, isiphumo sokutyeba se-hydroxypropyl methylcellulose sinokunyusa imfuno yamanzi yezinto ezisekwe kwisamente, ngaloo ndlela sandise isivuno se-mortar. I-mortar ezizilinganiselayo kunye ne-self-compact concrete, ezifuna ukunyibilika okuphezulu, zifuna i-viscosity ephantsi ye-hydroxypropyl methylcellulose. I-cellulose ether ene-viscosity ephantsi inokudlala isiphumo esihle sokumisa, ithintele ukutyibilika kwe-slurry, kwaye inomsebenzi wokopha, onokuqinisekisa ukuba awuyi kuchaphazela isiphumo sokuhamba kwezinto ze-mortar ezizilinganiselayo, kulula ukuyakha, kwaye inokugcinwa kwamanzi aphezulu. Iimpawu zingenza isiphumo somphezulu emva kokutyibilika sibe ngcono, sinciphise ukushwabana kwe-mortar, kwaye siphephe ukuxobula imifantu njalo njalo.
I-Hydroxypropyl methylcellulose isetyenziswa kakhulu kwizixhobo zokwakha ezahlukeneyo. Xa isetyenziswa kwi-mortar e-self-leveling, ineempawu ezilandelayo:
1. Ukusebenza okuphezulu kokugcina amanzi kunokwandisa ixesha lokusebenza kwe-mortar yokuzilinganisa, kuphucule ukuqina kwe-mortar, kwandise amandla ayo okubopha, kwaye ukusebenza kakuhle kwe-marting bonding kunokunciphisa uthuthu lokufika.
2. Ukuhambelana okuqinileyo, okufanelekileyo kuzo zonke iintlobo zezinto zokwakha, i-mortar ekwaziyo ukulinganisa, ukunciphisa ixesha lokutshona, ukunciphisa izinga lokuwoma kwayo, kunye nokuthintela iingxaki ezinje ngokuqhekeka nokugquma kweendonga kunye nomgangatho.
3. Ukuthintela ukopha, kunokudlala indima engcono kwi-suspension, kuthintele ukutyibilika kwe-slurry kwi-sedimentation kunye nokusebenza ngcono kokopha.
4. Gcina ukusebenza kakuhle kokuhamba kwamanzi, i-viscosity ephantsii-hydroxypropyl methylcelluloseayizukuchaphazela ukuhamba kodaka, ulwakhiwo olulula, ukusebenza kakuhle kokugcinwa kwamanzi, inokuvelisa isiphumo esihle somphezulu emva kokuzilinganisa, kwaye iphephe ukuqhekeka kwimeko yeedrama, ukusebenza okuzinzileyo kokubopha kwe-cellulose ether kuqinisekisa ngokupheleleyo ukugeleza okuhle kunye nokukwazi ukuzilinganisa. Ukulawula izinga lokugcina amanzi kunokuyenza iqine ngokukhawuleza kwaye kunciphise ukushwabana nokuqhekeka.
