HPMC YB 4000
EiponCellHPMC E4000 waa hydroxypropyl methyl cellulose ether si gaar ah loogu talagalay isticmaalka dhoobada.Hydroxypropyl methylcellulose (HPMC) waa eter cellulose aan-ionic ahayn oo laga soo qaatay cellulose maadada polymer-ka dabiiciga ah iyada oo loo marayo taxane ah hababka etherification.Waa budo cad oo aan ur lahayn, dhadhamin, oo aan sun ahayn.Marka lagu daro biyo qabow, waxay sameeyaan xal kolloidal ah oo cad ama waxoogaa daruur ah.HPMC waxay leedahay siyaalo dhowr ah sida dhumucdi, kala firdhinta, emulsifying, film samaynta, hakinta, adsorbing, dhaqdhaqaaqa dusha sare, xajinta qoyaanka, iyo ilaalinta kolloidka.Waxa ay ka heshaa codsiyo ballaadhan warshado kala duwan, oo ay ku jiraan qalabka dhismaha, warshadaha dahaadhka, resin synthetic, warshadaha dhoobada, dunta, beeraha, kiimikooyinka maalinlaha ah, iyo in ka badan.

HPMC YB 810M
EipponCell HPMC 810M waa Hydroxypropyl Methylcellulose (HPMC), oo sidoo kale loo yaqaan Hypromellose iyo Cellulose Hydroxypropyl Methyl Ether.Waxaa laga soo qaatay cellulose cudbi ah oo aad u saafi ah waxayna maraysaa hab gaar ah oo etherification hoos xaaladaha alkaline.HPMC waxay soo bandhigtaa sifooyinka kulaylka.Marka xalkeeda aqueous la kululeeyo, waxay samaysaa jel oo soo da'aya, kaas oo markaa dib loo milmi karo marka la qaboojiyo.Heerkulka gelation-ku wuu kala duwan yahay iyadoo ku xiran sifooyinka alaabta gaarka ah.Solubility waxaa saameeya viscosity, oo leh viscosity hoose taasoo keentay milmayn weyn.Kala dirida HPMC ee biyaha ma saamayso qiimaha pH.
HPMC waxa ay leedahay siyaalo badan oo caan ah, oo ay ku jiraan awoodda dhumucdi, dheecaanka milixda, xasiloonida pH, haynta biyaha, xasiloonida cabbirka, kartida samaynta filimaanta aad u wanaagsan, caabbinta ensaymka balaadhan, kala firdhisanaanta, iyo isku xidhnaanta.Faahfaahin kasta oo HPMC ah ayaa laga yaabaa inay muujiso kala duwanaansho yar oo guryahan ah.

HPMC YB 6000
EipponCellHPMC 6000 waa hydroxypropyl methyl cellulose ether si gaar ah loogu talagalay codsiyada dhoobada.Daraasad, qaybo kala duwan oo ah hydroxypropyl methyl cellulose budada ah (HPMC) iyo istaarijka ayaa loo isticmaalay sidii kuwa isku xira habka extrusion ee jirka cagaaran ee nitride silicon.Baaritaanku wuxuu diiradda saaray qiimeynta xoogga foorarsiga saddexda-dhibcood ee shaybaarada iyo falanqaynta qaab-dhismeedka yar ee dusha jabka.
Natiijooyinka ayaa shaaca ka qaaday in HPMC ay saameyn weyn ku yeelatay kor u qaadista xoogga cagaaran marka loo eego isticmaalka istaarijka.Isku darka 10% HPMC sida xidhe ahaan waxay keentay xoog dabacsanaan ah 29.3±3.1 MPa, taas oo qiyaastii 7.5 jeer ka sarraysa agabka la midka ah ee isticmaalaya istaarijka.Korodhka la taaban karo ee xoogga waxa loo aaneeyey joogitaanka qaybo HPMC ah oo aan dhab ahayn, kuwaas oo isu waafajiyey jihada extrusion oo muujiyay hab-dhaqan ka bixitaan ah inta lagu jiro imtixaanka foorarsiga.
