Njengenye yezinto ezibalulekile ze-cellulose ether admixtures ku-powder dry mortar, i-hydroxypropyl methylcellulose inemisebenzi eminingi edaka.Indima ebaluleke kakhulu ye-hydroxypropyl methylcellulose odakeni lukasimende ukugcinwa kwamanzi nokujiya.Ngaphezu kwalokho, ngenxa yokusebenzelana kwayo nohlelo lukasimende, ingaphinda idlale indima eyisizayo ekufakeni umoya, ukubuyisela emuva, kanye nokuthuthukisa amandla ebhondi eqinile.umphumela.
Ukusebenza okubaluleke kakhulu kwe-hydroxypropyl methylcellulose odakeni ukugcinwa kwamanzi.Njengengxube ye-cellulose ether odakeni, i-hydroxypropyl methylcellulose ingasetshenziswa cishe kuyo yonke imikhiqizo yodaka, ikakhulukazi ngenxa yokugcinwa kwayo kwamanzi.Ngokuvamile, ukugcinwa kwamanzi kwe-hydroxypropyl methylcellulose kuhlobene ne-viscosity yayo, izinga lokushintshwa kanye nosayizi wezinhlayiyana.
IHydroxypropyl methylcellulose isetshenziswa njenge-thickener, futhi umphumela wayo wokujiya uhlobene nezinga lokushintsha, usayizi wezinhlayiyana, i-viscosity kanye nezinga lokuguqulwa kwe-hydroxypropyl methylcellulose.Ngokuvamile, ukuphakama kwezinga lokushintshwa kanye ne-viscosity ye-cellulose ether, kanye nezinhlayiya ezincane, umphumela wokujiya ubonakala nakakhulu.
Ku-hydroxypropyl methylcellulose, ukwethulwa kwamaqembu e-methoxy kunciphisa amandla angaphezulu esixazululo esinamanzi esine-hydroxypropyl methylcellulose, ukuze i-hydroxypropyl methylcellulose ibe nomthelela wokungenisa umoya odakeni lukasimende.Yethula amabhamuza omoya afanele odakeni, ngenxa “yomphumela webhola” wamabhamuza omoya,
Ukusebenza kokwakhiwa kodaka kuyathuthukiswa, futhi ngesikhathi esifanayo, ukwethulwa kwama-bubbles emoyeni kwandisa izinga lokukhipha udaka.Yiqiniso, inani lokungena emoyeni lidinga ukulawulwa.Ukungena komoya okuningi kuzoba nomthelela omubi emandleni odaka.
I-Hydroxypropyl methylcellulose izobambezela inqubo yokumisa usimende, ngaleyo ndlela ibambezele inqubo yokumisa kanye nokuqina kukasimende, futhi yandise isikhathi sokuvula udaka ngokufanele, kodwa lo mphumela awulungile odakeni ezindaweni ezibandayo.
Njengento ye-polymer enochungechunge olude, i-hydroxypropyl methylcellulose ingathuthukisa ukusebenza kwesibopho ne-substrate ngemva kokwengezwa ohlelweni lukasimende ngaphansi kwesisekelo sokugcina umswakama ngokugcwele odongeni.
Ukufingqa, ukusebenza kweI-HPMCodakeni ikakhulukazi kuhlanganisa: ukugcinwa kwamanzi, ukuqina, ukwandisa isikhathi sokumisa, ukufaka umoya nokuthuthukisa amandla ebhondi eqinile, njll.
