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 sokusetha, ukufaka umoya nokuthuthukisa amandla ebhondi eqinile, njll.
