Astaamaha ugu muhiimsan ee hydroxyethyl cellulose waa in ay ku milmaan biyo qabow iyo biyo kulul, oo aan lahayn sifooyin gelling ah.Waxay leedahay heerar kala duwan oo ah beddelka shahaado, solubility iyo viscosity.roobab.Xalka Hydroxyethyl cellulose wuxuu sameyn karaa filim hufan, wuxuuna leeyahay sifooyinka nooca aan-ionic ahayn ee aan la falgelin ion oo leh iswaafajin wanaagsan.
① Heerkulka sare iyo milanka biyaha: Marka la barbardhigo methyl cellulose (MC), kaas oo kaliya lagu milmo biyo qabow, hydroxyethyl cellulose waxaa lagu milmi karaa biyo kulul ama biyo qabow.Kala duwanaansho balaadhan oo ah guryaha milanka iyo viscosity, iyo gelation-ka aan kulaylka ahayn.
② Iska caabbinta milixda: Sababtoo ah nooca aan-ionic ahayn, waxay la noolaan kartaa polymers-ka kale ee biyaha ku milma, surfactants iyo cusbada oo ballaaran.Sidaa darteed, marka la barbar dhigo ionic carboxymethyl cellulose (CMC), hydroxyethyl cellulose waxay leedahay iska caabin milix fiican.
③ Biyaha haynta, simida, samaynta filimada: awoodeeda biyo-hayntu waa laba jeer ka methyl cellulose, oo leh nidaam qulqulaya oo aad u fiican iyo samaynta filim heer sare ah, hoos u dhigista dareeraha, luminta, galmada kolloid ilaalinta.
Isticmaalka hydroxyethyl cellulose
Hydroxyethyl cellulose waa badeecada ether-ka cellulose-ka ah ee aan-ionic-ka-milmi karin, oo si ballaaran loogu isticmaalo daaha-dhismaha, batroolka, polymerization, daawada, isticmaalka maalinlaha ah, warqad iyo khad, dhar, dhoobo, dhismo, beero iyo warshado kale.Waxay leedahay hawlaha dhumucda, isku xidhka, emulsifying, kala firdhinta iyo xasilinta, oo hayn kartaa biyaha, samayn kartaa filim iyo bixinta saamaynta kolloid ilaalinta.Waxay si fudud ugu milmi kartaa biyo qabow iyo biyo kulul, waxayna ku siin kartaa xal leh aragti ballaadhan.Mid ka mid ah ether-ka cellulose-ka ugu dhaqsaha badan.
1 rinji cinjir ah
Hydroxyethyl cellulose waa dhumucda ugu badan ee loo isticmaalo daaha cinjirka.Marka lagu daro dhumucda lakabka cinjirka, waxa kale oo ay komi kartaa, kala diri kartaa, xasilin kartaa oo hayn kartaa biyaha.Waxaa lagu gartaa saameyn dhumuc weyn leh, horumarinta midabka wanaagsan, hantida filim sameynta iyo xasilloonida kaydinta.Hydroxyethyl cellulose waa soosaar cellulose aan ionic ahayn oo loo isticmaali karo pH ballaaran.Waxay si fiican ula jaanqaadi kartaa walxaha kale ee ka kooban (sida midabada, waxyaabaha lagu daro, buuxinta iyo cusbada).Dahaarka ku dhumucsan ee hydroxyethyl cellulose waxay leeyihiin rheology wanaagsan oo heerar kala duwan oo xiirid ah waana pseudoplastic.Hababka dhismaha sida burushka, dahaarka rullaluistuadka, iyo buufinta ayaa la isticmaali karaa.Dhisme wanaagsan, ma fududa in lagu tifxo, sagxdo oo firdhiso, iyo simi fiican.
2 polymerization
Hydroxyethyl cellulose waxa uu leeyahay hawlaha kala firdhiso, emulsifying, laalista iyo xasilinta ee polymerization ama qaybaha copolymerization ee resins synthetic, iyo waxa loo isticmaali karaa sida kolloid ilaalinta.Waxaa lagu gartaa awood xoog leh oo kala firdhisan, "filim" khafiif ah oo qaybo ka mid ah, cabbirka qaybta ganaaxa, qaabka qayb ka mid ah, nooca dabacsan, dheecaanka wanaagsan, daahfurnaanta alaabta sare iyo farsamaynta sahlan.Sababtoo ah hydroxyethyl cellulose waxaa lagu milmi karaa biyo qabow iyo biyo kulul, oo aan lahayn meel heerkulka gelling ah, waxay aad ugu habboon tahay falcelinta polymerization ee kala duwan.
Sifooyinka muhiimka ah ee jireed si loo baaro tayada kala firdhiyaa waa xiisadda dusha sare (ama isdhexgalka), xoogga isdhexgalka iyo heerkulka gelation ee xalkeeda aqueous.Sifooyinkan hydroxyethyl cellulose waxay ku habboon yihiin polymerization ama copolymerization of resins synthetic.
Hydroxyethyl cellulose waxay leedahay iswaafajin wanaagsan oo leh ethers cellulose-ka kale ee biyaha ku milma iyo PVA.Nidaamka isku dhafan ee sidaas loo sameeyay wuxuu heli karaa saameyn dhamaystiran oo ah barashada midba midka kale ku wanaagsan yahay iyo buuxinta daciifnimada qofka.Badeecadaha resin-ka isku dhafan kaliya ma laha tayada wanaagsan, laakiin sidoo kale waxay yareeyaan khasaaraha alaabta.
3 shidaal qodis ah
Qoditaanka saliidda iyo soo saarista, viscosity hydroxyethyl cellulose inta badan waxaa loo isticmaalaa viskosifier si loo dhamaystiro dareerayaasha iyo dareerayaasha dhammaynta.Viscosity hoose ee hydroxyethyl cellulose waxa loo istcimaalaa dareere luminaya.Dhoobo kala duwan oo loo baahan yahay qodista, dhamaystirka, sibidhka iyo hawlgallada jabinta, hydroxyethyl cellulose waxa loo isticmaalaa dhumuc ahaan si loo helo dareere wanaagsan iyo xasiloonida dhoobada.Inta lagu jiro qodista, waxay wanaajin kartaa awoodda qaadista ciidda ee dhoobada waxayna sii dheerayn kartaa nolosha adeegga qashinka.Dareeraha dhamaystirka adag ee hooseeya iyo dareeraha sibidhka, sifooyinka wanaagsan ee yaraynta khasaaraha biyaha ee hydroxyethyl cellulose waxay ka hortagi kartaa qadar badan oo biyo ah oo ka soo galaya lakabka saliidda ee dhoobada, waxayna hagaajin kartaa awoodda wax soo saarka ee lakabka saliidda.
4 Kiimikada maalinlaha ah
Hydroxyethylcellulose waa filim hore oo wax ku ool ah, xire, dhumuc weyn, xasiliye iyo kala firdhiyaa shaambada, buufinta timaha, dhexdhexaadiyeyaasha, qaboojiyaha iyo waxyaabaha la isku qurxiyo;ku jira budada saabuunta Waa wax wasakh dib u dhiga.Hydroxyethyl cellulose waxay si dhakhso ah u milmaan heerkul sare, taas oo dedejin karta habka wax soo saarka iyo hagaajinta waxtarka wax soo saarka.Muuqaalka muuqda ee saabuunta ka kooban hydroxyethyl cellulose waa in ay wanaajiso jilicsanaanta iyo ka ganacsiga dharka.
