Cellulose-Hydroxyethyl Methylcellulose oo loogu talagalay Xabagta dhoobada dhoobada ah

Waxqabadka hydroxyethyl methylcellulose ee dhoobada dhoobada dhoobada: saameyn wanaagsan oo anti-sag ah, waqti dheer oo furitaan ah, xoog hore oo sarreeya, la qabsiga heerkulka sare ee xooggan, fududahay in la walaaqo, fududahay in la shaqeeyo, mindi aan dhejin, iwm.

Guryaha alaabta

Biyo milanka iyo awoodda dhumucda: Hydroxyethyl methylcellulose waxay ku milmaysaa biyo qabow, samaynta xal hufan oo muuqda.

Si fudud ugu milmi kara dareerayaasha organic: joogitaanka qadar go'an oo kooxaha methoxy hydrophobic, hydroxyethyl methylcellulose waxay ku milmay qaar ka mid ah dareerayaasha organic iyo dareerayaasha kuwaas oo biyaha iyo walxaha organic ay isku dhafan yihiin.

Dulqaadka milixda: Maadaama hydroxyethyl methylcellulose uu yahay mid aan-ionic ahayn, oo aan polymer-ka ahayn electrolyte, waxay ku xasilloon tahay xalalka aqueous ee cusbada birta ah ama electrolytes organic.

Dhaqdhaqaaqa dusha sare: Xalalka biyaha leh ee hydroxyethyl methylcellulose ayaa korka firfircoon sidaa darteedna waxay leeyihiin saameyn emulsifying.

Gelation-ka kulaylka: Marka kulaylka ka sarreeya heerkul gaar ah, hydroxyethyl methylcellulose xal aqueous wuxuu noqdaa mid mugdi ah oo soo da'aya, taasoo keenaysa in xalku lumiyo viscosity. Laakiin si tartiib tartiib ah ayuu u qaboojiyaa oo u beddelaa xaaladda asalka ah ee xalka. Heerkulka uu ku dhaco xinjirowga iyo roobka wuxuu ku xiran yahay nooca badeecada, xoojinta xalka iyo heerka kuleylka.

Maaddooyinka dambaska hooseeya: Sababtoo ah hydroxyethyl methylcellulose waa non-ionic waxaana si hufan loogu sifayn karaa biyo kulul inta lagu jiro habka diyaarinta, waxa ku jira dambaska waa mid aad u hooseeya.

Xasiloonida PH: Viscosity of hydroxyethyl methylcellulose xal aqueous ah ayaa si dhib leh u saameeya alkali. Alaabtani waa mid xasiloon inta u dhaxaysa pH ee 3.0-11.0.

Saamaynta biyaha-haynta: Maadaama hydroxyethyl methylcellulose uu yahay hydrophilic iyo xalkeeda aqueous-ku leeyahay viscosity sare, iyada oo lagu darayo hoobiye, malaastaan, rinji, iwm. waxay ilaalin kartaa saamaynta biyaha-haysashada sare ee alaabta.

Haysashada qaabka: Marka la barbar dhigo polymers-ka kale ee biyaha ku milma, xalka aqueous ee hydroxyethyl methylcellulose wuxuu leeyahay sifooyin viskoelastic ah oo gaar ah. Waxaa lagu daraa feeraha si loo hagaajiyo awoodda walxaha dhoobada ah ee la soo saaray si ay u xajistaan ​​qaabkooda.

Saliid: Ku darida alaabtan waxay yarayn kartaa isku xidhka isku xidhka alaabta dhoobada ah ee la soo saaray iyo alaabta sibidhka waxayna wanaajisaa saliidda.

Guryaha sameynta filimada: Hydroxyethyl methylcellulose waxay sameyn kartaa xaashi adag, dabacsanaan, hufan oo saliid wanaagsan iyo caabbinta esterka. Waxay si aad u wanaagsan u kordhin kartaa viscosity ee hoobiye sibidhka. Isticmaalka hoobiye cusub oo leh viscosity habboon wuxuu ahaan karaa mid xasiloon oo aan dhiig-baxin muddo cayiman, taasoo ka dhigaysa hoobiye mid aad u fudud in la simi karo oo si wax ku ool ah u wanaajiyo waxqabadka dhismaha.
