I-Hydroxypropylm methylcellulose i-ether engekho i-ether ye-moulsose esebenza kusuka kukotini ecwengekile ngochungechunge lokuphendula kwamakhemikhali. Kuyinto engenaphunga, engenalo ubuthi obumhlophe obucwebezelayo obuncibilika emanzini futhi baletha isixazululo esicacile noma esinamafu kancane. Inezici zokuqina, ukugcinwa kwamanzi kanye nokwakhiwa okulula. Isixazululo samanzi se-hydroxypropyllylylylc HPMC sizinzile kakhulu kuhla lwe-HP3.0-10.0, futhi lapho kungaphansi kwama-3 noma ngaphezulu kune-10, i-viscosity izoncishiswa kakhulu.
Umsebenzi oyinhloko we-hydroxypropyllylylyl methylcellulose ku-celtenswatar ngosimende kanye no-putty powder ukugcinwa kwamanzi nokuqina, okungathuthukisa kahle ukubumbana kanye nokumelana kahle kwezinto zokwakha.
Izici ezinjengokushisa kanye nesivinini somoya zizothinta izinga lokuzithambisa umswakama ngodaka, ama-putty neminye imikhiqizo, ngakho-ke ngemikhiqizo ehlukene, umphumela wokugcinwa kwamanzi, imiphumela yokugcinwa kwamanzi enezinto ezifanayo ze-cellulose eyengeziwe izoba nokwehluka okufanayo. Ekwakhiweni okuthize, umphumela wokugcinwa kwamanzi we-slurry ungashintshwa ngokwanda noma ukwehlisa inani le-HPMC elingeziwe. Ukugcinwa kwamanzi kwe-hydroxypropylllylylylyl hpmc ekushiseni okuphezulu kuyinkomba ebalulekile yokuhlukanisa ikhwalithi ye-HPMC. I-HPMC enhle kakhulu ingaxazulula ngempumelelo inkinga yokugcinwa kwamanzi ngaphansi kwezimo eziphakeme zokushisa. Ezikhathini ezomile nasezindaweni ezinokushisa okuphezulu kanye nesivinini somoya esiphakeme, kuyadingeka ukusebenzisa i-HPMC esezingeni eliphakeme ukuthuthukisa ukusebenza kokugcinwa kwamanzi kwe-slurry.
Ngakho-ke, ekushiseni okuphezulu kwehlobo lasehlobo, ukuze kufinyelelwe umphumela wokugcina amanzi, kuyadingeka ukwengeza inani elanele le-HPMC ephezulu kakhulu ngokuya ngefomula, ngaphandle kwalokho kuzoba nezinkinga zekhwalithi ezifana ne-hydration enganele, ukuncipha kwamandla, ukuqhekeka , eboshwe nokuchithwa okubangelwa ukomisa okusheshayo kakhulu, futhi ngasikhathi sinye futhi kwandise ubunzima bokwakhiwa kwabasebenzi. Njengoba amazinga okushisa ehla, inani le-HPMC elingeziwe lingancishiswa kancane kancane, futhi imiphumela efanayo yokugcina amanzi ingatholakala.
Ekwenziweni kwezinto zokwakha, i-hydroxypropyllykyllose yiyona esengezo esisemqoka. Ngemuva kokungeza i-HPMC, izakhiwo ezilandelayo zingathuthukiswa:
1. Ukugcinwa kwamanzi: Thuthukisa ukugcinwa kwamanzi, thuthukisa udaka kasimende, u-drew powder ubeka ama-putty ukumiswa okusheshayo okusheshayo nokunganele kwe-hydration kubangele ukuba lukhuni, ukuqhekeka kanye nezinye izinto.
2. Ukunamathela: Ngenxa yeplastiki ethuthukisiwe yodaka, ingavuselela kangcono i-substrate kanye nokuhlengwa.
3. Anti-sagging: Ngenxa yomphumela wayo wokuqina, kungavimba ukushelela kodaka kanye nezinto ezinamathela ngesikhathi sokwakha.
4. Ukusetshenziswa: Khulisa ububanzi beplastiki yodaka, uthuthukise ukusebenza kwezimboni zokwakha futhi uthuthukise ukusebenza kahle komsebenzi.
