Hydroxypropyl methyl cellulose (HPMC) waa noocyo kala duwan oo ether ah oo isku dhafan oo wax soo saarkeeda, qiyaasta iyo tayada ay si xawli ah u kordheysay sanadihii ugu dambeeyay.Cellulose aan-ionic ahayn oo isku qasan eter ay sameeyeen habab kale.
HPMC waxay leedahay kala firdhiso, emulsifying, dhumucdi, isku xidhnaan, biyo-hayn iyo sifooyin xanjo-haysasho wanaagsan.Waxay ku milmi kartaa biyaha, waxaana sidoo kale lagu milmi karaa ethanol iyo acetone ka hooseeya 70%.HPMC oo leh qaab dhismeed gaar ah ayaa sidoo kale si toos ah loogu milmi karaa ethanol.HPMC waxaa si balaadhan loogu isticmaali karaa sida daahan filimada, wakiilka sii daayo joogtada ah iyo xidhe ee diyaargarowga dawooyinka, iyo sidoo kale si weyn loogu isticmaali karaa petrochemicals, qalabka dhismaha, ceramics, dunta, cuntada, kiimikooyinka maalin kasta iyadoo la isticmaalayo dhumucdiisuna, kala firdhiyey, emulsifying iyo film-samaynta. guryaha., xabagta synthetic, dawooyinka, rinjiga iyo elektiroonigga iyo meelaha kale.
Habka wax soo saarka ee HPMC waxa loo qaybin karaa laba qaybood: Habka wejiga gaaska iyo habka wejiga dareeraha.Waqtigan xaadirka ah, wadamada horumaray sida Yurub, Maraykanka iyo Japan waxay isticmaalaan habab badan oo gaas-waji ah, iyaga oo isticmaalaya saxarka alwaax sida alaabta ceeriin (cududda suufka ayaa loo isticmaalaa in lagu soo saaro alaabooyin badan oo viscosity ah), alkalization iyo etherification ayaa lagu fuliyaa falcelin isku mid ah. qalabka, falcelinta ugu weynina waa falcelin toosan.Killidu waxay leedahay usheeda dhexe ee toosan iyo mindi duuleysa oo wareegeysa oo si gaar ah loogu talagalay soo saarista etherka cellulose, taas oo heli karta saameyn isku dhafan oo wanaagsan.
Falanqeeyayaasha warshadaha ee Xinjie ayaa sheegay in kobaca dhaqaalaha ee joogtada ah iyo hagaajinta joogtada ah ee tayada nolosha dadka, baahida loo qabo hydroxypropyl methylcellulose ee suuqa Shiinaha ayaa sii waday inay korodho.Muddo dheer, baahida suuqa ee hydroxypropyl methylcellulose ee dalkaygu waxay inta badan ku urursan tahay dhinacyada dhismaha iyo dahaarka.Iyadoo horumarinta joogtada ah ee warshadaha hoose, baahida loo qabo hydroxypropyl methylcellulose ee cuntada iyo beeraha dawooyinka ayaa bilaabay inay si degdeg ah u ballaariso.Mustaqbalka, dhismaha, cuntada iyo warshadaha dawooyinku waxay noqon doonaan xoog horseed u ah koritaanka suuqa dalkayga hydroxypropyl methylcellulose.
