Isingeniso:
Endaweni yokwakha, udaka udlala indima ebaluleke kakhulu, esebenza njenge-ejenti ebophayo yezinto ezahlukahlukene zokwakha. Ukwehlukaniswa kodaka kuguqulwe kakhulu ngokuhamba kwesikhathi, kuhlanganisa izengezo ukuthuthukisa ukusebenza nokubhekana nezinselelo ezithile. Enye yesengezo enjalo, i-hpdroxypropyl methylcellulose (HPMC), ithole ukuvelela kweminikelo yayo ehlukahlukene ekwakhiweni kodaka. Lokhu kuhlola okuphelele kwezakhiwo, ukusebenza, kanye nokusetshenziswa kwe-HPMC e-Deccurcculch Gunya udaka, kucacisa ukubaluleka kwako emikhubeni yanamuhla yokwakha.
Ukuqonda i-Hydroxypropyllykyl methylcellulose (HPMC):
I-Hydroxypropylm methylcellulose, i-cellulose ether etholwa, ivela njengenkinobho yesifunda ekwenziweni kokwakhiwa kodaka kodaka ngenxa yezakhiwo zayo ezihlukile. Kususelwa ku-cellulose, i-HPMC ithola ukuguqulwa kwamakhemikhali ukuhambisa izici ezifiselekayo njengokugcinwa kwamanzi, amandla okuqina kanye nokusebenza okuthuthukile. Isakhiwo saso samangqamuzana sinamaqembu we-hydroxypropyl kanye ne-methoxyl, lula ukusebenzisana ngama-molecule wamanzi nezinto zokwakha dementile.
Izakhiwo kanye nokusebenza kwe-HPMC eDistast Sacking:
Ukugcinwa kwamanzi: I-HPMC ibonisa amandla okugcina amanzi ayingqayizivele, ebalulekile ekusekeleni inqubo ye-hydration ku-wortar. Ngokwakha ifilimu elincanyana elizungeze izinhlayiyana kasimende, linciphisa ukulahleka kwamanzi ngokuhwamuka, liqinisekisa ukuthi i-hydration ezanele futhi ithuthukise amandla aphelele nokuqina kodaka.
Ukuguqulwa kwe-Rheelogy: Ukungezelelwa kwe-HPMC kuthonya izakhiwo ze-bheological zodaka, ukudlulisela indlela yokuziphatha ye-thixotropic ethuthukisa uhlelo lokusebenza nokusebenza. Ilawula i-viscosity, ivimbela ukugcwala noma ukuncipha ngesikhathi sohlelo lokusebenza mpo, ngaleyo ndlela kusiza ukusebenza okubushelwa khona.
I-Adhesion ethuthukisiwe: I-HPMC igqugquzela ukunamathela phakathi kodaka kanye nezindawo zokuhlobisa ezingaphezulu, ukukhuthaza izibopho ezinamandla zokuxhumana. Le mfanelo inzuzo ikakhulukazi ekunikezelweni kwezicelo, lapho ukubambelela kubahlinzeki abahlukahlukene kubalulekile ukuze kufezeke ukuqeda okufanayo kanye nokuqina okuqinile.
Ukumelana nokuqhekeka: Ukufakwa kwe-HPMC kunomthelela ekunciphiseni kokuqhekeka okubangelwa yi-shrinkage e-Plaster Datar. Ngokulawula ukuhwamuka komswakama kanye nokuthuthukisa ubumbano, kunciphisa ukwenzeka kwemifantu engaphezulu, ngakusozelele ukudluliswa kwezinhlekelele kanye nobuqotho bezinhlekelele zendawo eqediwe.
Izicelo ze-HPMC esongwini wohlobo lwezokwakha:
Ukuhunyushwa kwangaphandle: I-HPMC-Encuchise Fortar Fotctions Thola uhlelo lokusebenza olubanzi ekunikezelweni kwangaphandle, lapho ukuqina kwesimo sezulu nokuqina kubaluleke kakhulu. Izakhiwo eziphakeme zokugcina amanzi ze-HPMC ziqinisekisa i-hydration ende, zinika amandla ukwakheka kokumbona okunamandla kombuso okwazi ukubekezelela izimo zemvelo ezinzima.
Ukulungiswa Kwangaphakathi: Ku-Interior Plastering Application, i-HPMC isiza impumelelo yokuqedwa kwamandla abushelelezi, anobunzima ngephutha elingaphezulu komhlaba. Imiphumela yayo yokuguqula i-Rheology inika amandla ukulawulwa okuqondile kokungaguquguquki kodaka, kusiza uhlelo lokusebenza olungenamandla nokuqeda, ngaleyo ndlela kuthuthukise isikhalazo esihle sezikhala zangaphakathi.
Ukulungiswa kodaka: I-HPMC idlala indima ebalulekile ekwakhekeni kwama-maromial malls asetshenziselwa ukulungiswa kokhonkolo noma ama-substrates ewohloka. Ngokuthuthukisa amandla amabhondi nokumelana nokuqhekeka, kusiza ukubuyiselwa kobuqotho bezinhlekelele ngenkathi kuqinisekisa ukuhambisana nezinto zokwakha ezikhona.
Ama-tile anamathela kanye nama-grouts: ngaphezu kwezicelo zokubumba, i-hpmc ithola ukusetshenziswa kwezithako ezinamathele nama-grouts, lapho kudlulisela khona izakhiwo ezibalulekile njengokugcinwa kwamanzi, ukunamathela, kanye nokusebenza. Ukuhambisana kwalo ngezithasiselo ezahlukahlukene kanye nama-filler kuthuthukisa ukusebenza nokuguquguquka kwezinhlelo zokufaka tile.
IZINSELELE NOKUFUNDA:
Ngenkathi i-HPMC inikezela ngezinzuzo eziningi zokwakhiwa kodaka kodaka, izinselelo ezithile kanye nokunakwa kwe-tararetion. Ukuhlukahluka ngekhwalithi ebonakalayo ebonakalayo, umthamo, kanye nezimo zemvelo kungathonya ukusebenza kodaka olususelwa ku-HPMC, kudinga ukulawula kwekhwalithi okucacile kanye nokwenza kahle kwekhwalithi. Ngokwengeziwe, ukuhambisana nezinye izengezo kanye nama-admixtures kumele kuhlolwe ngokucophelela ukuqinisekisa imiphumela ye-synergistic futhi uvikele ukusebenzisana okubi okungashayisana ukusebenza kodaka.
I-Hydroxypropyl Methylcellulose (HPMC) ivela njengezengezo eziguquguqukayo ekwakhekeni kohlobo lwezokwakha ngodaka, inikeza inzuzo yezinzuzo ezisukela ekusebenzeni okuthuthukile nokunamathela ekulinganiseni ukuqina okuthuthukisiwe nokuqhekeka. Izakhiwo zayo ezihlukile zikwenza kubaluleke kakhulu emikhubeni yanamuhla yokwakhiwa, kusiza ukufezekiswa kokwakheka okuhlelekile, okujabulisa ubuhle, futhi okuhlala isikhathi eside. Njengoba imboni yezokwakha iyaqhubeka nokuvela, i-HPMC ilungele ukuhlala isengezo segumbi, ukushayela okusha kanye nokugqama kubuchwepheshe bodaka.
