I-Cellulose ether hpmc inomsebenzi wokugcina amanzi kanye nokuqina odakeni lukasimende nodaka olusekelwe ku-gypsum, olungathuthukisa ngokuphumelelayo ukunamathela kanye nokumelana okuqondile kwezinto zodaka.
Izinto ezifana nezinga lokushisa legesi, izinga lokushisa kanye nezinga lokucindezela komoya linomthelela omubi ezingeni lokuhwamuka komswakamo ovela kudaka lukasimende kanye nemikhiqizo esekelwe ku-gypsum.Ngakho-ke, kunomehluko othile ekungezeni inani elifanayo lemikhiqizo ye-HPMC ukuze kugcinwe ukusebenza kahle kwamanzi enkathini ngayinye.
Ekuthululeni ukhonkolo, umphumela wokuvala amanzi ungalungiswa ngokwandisa nokunciphisa ukugeleza kwe-fractional.Izinga lokugcinwa kwamanzi le-methyl cellulose ether ekushiseni okuphezulu yinani lenkomba elingukhiye lokuhlukanisa ikhwalithi ye-methyl cellulose ether.
Imikhiqizo yekhwalithi ephezulu ye-HPMC ingaxazulula ngempumelelo inkinga yokukhiya amanzi asezingeni eliphezulu.Ezinkathini zokushisa okuphezulu, ikakhulukazi ezindaweni ezishisayo nezinomswakama kanye nokwakhiwa kwechromatography, i-HPMC yekhwalithi ephezulu iyadingeka ukuze kuthuthukiswe ukugcinwa kwamanzi odaka.
I-HPMC yekhwalithi ephezulu ihlukaniswe kahle kakhulu, futhi amaqembu ayo e-methoxyl ne-hydroxypropyl asatshalaliswa ngokulinganayo ochungechungeni lwamangqamuzana e-cellulose, olungathuthukisa ikhono lama-molecule omoya-mpilo ukuze akhe izibopho eziqinile ku-hydroxyl ne-ether bond.
Ingakwazi ukulawula ngempumelelo ukuhwamuka kwamanzi okubangelwa isimo sezulu esishisayo futhi ifinyelele umphumela wokuvala amanzi aphezulu.Ikhwalithi ephezulu ye-methylcellulose HPMC ingasetshenziswa odakeni oluxubile kanye nokhonkolo lwemisebenzi yezandla yaseParis.
Gcoba zonke izinhlayiya eziqinile ukuze wenze ifilimu emanzi, futhi umswakama wesimiso uzokhishwa kancane kancane isikhathi eside, futhi usabele ngezinto ezingaphili kanye nezinto ze-collagen ukuqinisekisa amandla okubopha namandla aqinile.
Ngakho-ke, endaweni yokwakhiwa kwehlobo elishisayo, ukuze sifinyelele umphumela wokonga amanzi, kufanele sengeze imikhiqizo ye-HPMC esezingeni eliphezulu ngokusho kweresiphi, ngaphandle kwalokho, izobangelwa ukuntuleka kokuqina, amandla ancishisiwe, ukuqhekeka, isigubhu segesi. kanye nezinye izinkinga zekhwalithi yomkhiqizo.Ibangela ukoma ngokushesha okukhulu.
Lokhu kwandisa nobunzima bokwakha kubasebenzi.Njengoba izinga lokushisa lincipha, inani le-HPMC elengeziwe liyehla kancane kancane ukuze kuzuzwe umswakama ofanayo.
