I-Hydroxypropyl methylcellulose ether (HPMC) inokugcinwa kwamanzi kanye nemiphumela yokujiya odakeni lukasimende nodaka olusekelwe ku-gypsum, futhi ingathuthukisa ngokunengqondo ukunamathela nokumelana okuqondile nodaka.
Izinto ezifana nezinga lokushisa legesi, izinga lokushisa, nezinga lomfutho wegesi lilimaza izinga lokuhwamuka kwamanzi odakeni lukasimende kanye nemikhiqizo eyenziwe nge-gypsum.Ngakho-ke, inani elifanayo eliphelele le-commercial hydroxypropyl methylcellulose ether (HPMC) engezwe ukuze kugcinwe ukutholakala kwamanzi liyahlukahluka kuye ngesizini.
Lapho uthela ukhonkolo, umphumela wokukhiya amanzi ungalungiswa ngokusho kokwanda noma ukwehla kwezinga lokugeleza okuphezulu.Izinga lokukhiya amanzi le-hydroxypropyl methylcellulose ether ezingeni lokushisa eliphezulu liyinkomba eyinhloko yenani lokuhlukanisa ikhwalithi ye-hydroxypropyl methylcellulose ether.
Imikhiqizo yekhwalithi ephezulu ye-hydroxypropyl methylcellulose ether (HPMC) ingakwazi ukubhekana nenkinga yokuvala amanzi okushisa okuphezulu.Ezikhathini zokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezinomswakama kanye nezakhiwo zobunjiniyela be-chromatography, kuyadingeka ukusebenzisa ikhwalithi ephezulu ye-hydroxypropyl methylcellulose ether (HPMC) ukuze kuthuthukiswe ukunyibilika kwamanzi kwe-slurry.
Ingxenye yekhwalithi ephezulu ye-hydroxypropyl methylcellulose ether (HPMC) ifana kakhulu, futhi amaqembu ayo e-methoxy ne-hydroxypropyl asatshalaliswa ngokulinganayo ochungechungeni lwesakhiwo samangqamuzana e-methyl cellulose, engathuthukisa ukukhiqizwa kwama-oxygen molecule ku-hydroxyl ne-ether bond.Amandla we-covalent bond ukusebenza.
Ingakwazi ukulawula ukuhwamuka kwamanzi okubangelwa ukushisa futhi ifinyelele umphumela wangempela wokukhiya amanzi aphezulu.I-Hydroxypropyl Methylcellulose Ether (HPMC) yekhwalithi ephezulu itholakala kuzo zonke izigxobo ezixubekile kanye nokhonkolo lwemisebenzi yezandla yaseParis.
Zonke izinhlayiya eziqinile zihlanganiswe ukuze zenze ifilimu emanzi.Amanzi avamile akhishwa kancane kancane isikhathi eside futhi abhekana nokuhlangana kwezinto ezingaphili nezinto ze-collagen ukuze kuqinisekiswe amandla okucindezela okubophayo namandla aqinile.
Ngakho-ke, ezindaweni zokwakha ezisezingeni lokushisa eliphezulu ehlobo, ukuze kuzuzwe umphumela wangempela wokonga amanzi, abantu kufanele bengeze imikhiqizo yekhwalithi ephezulu ye-hydroxypropyl methylcellulose ether (HPMC) ngokuya ngeresiphi eyimfihlo, ngaphandle kwalokho bazobe beshoda ngamanzi ngenxa ukuntuleka kwamanzi.Izinkinga zekhwalithi yomkhiqizo ezifana nokuqiniswa, amandla okucindezela ancishisiwe, ukuqhekeka, amaqhuqhuva komoya, njll. kubangela ukomisa ngokweqile.
Lokhu kwandisa nobunzima bokwakha kubasebenzi.Njengoba izinga lokushisa lincipha, inani elingeziwe le-hydroxypropyl methylcellulose ether (HPMC) liyehla kancane kancane ukuze kuzuzwe umswakama ofanayo.
