Heerka qodista saliidda HEC
qodista saliidda darajoHEC Hydroxyethyl cellulosewaa nooc ka mid ah nonionic soluble cellulose ether, oo ku milma biyaha kulul iyo kuwa qabow labadaba, oo leh dhumuc, laalitaan, dhejis, emulsification, samaynta filim, haynta biyaha iyo ilaalinta guryaha kolloid. Si weyn loogu isticmaalo rinjiga, waxyaabaha la isku qurxiyo, qodista saliidda iyo warshadaha kale. Heerka qodista saliidda HECwaxaa loo isticmaalaa sidii dhumucyo dhoobo kala duwan oo looga baahan yahay qodista, dejinta ceelasha, sibidhka iyo hawlgallada jajabinta si loo gaaro dheecaan wanaagsan iyo xasillooni. Hagaajinta gaadiidka dhoobada inta lagu jiro qodista iyo ka hortagga xaddi badan oo biyo ah inay soo galaan kaydka kaydka ayaa dejinaya awoodda wax soo saarka kaydka.
Astaamaha hydroxyethyl cellulose
Sida surfactant-aan-ionic ah, hydroxyethyl cellulose waxay leedahay sifooyinka soo socda marka lagu daro dhumuc, laalitaan, isku-xidhka, sabaynta, samaynta filimada, kala firdhinta, haynta biyaha iyo bixinta kolloid ilaalin ah:
1, HEC waxaa lagu milmi karaa biyo kulul ama qabow, heerkulka sare ama karkarinta ma soo da'do, si ay u leedahay noocyo kala duwan oo milmi iyo viscosity guryaha, iyo jel aan kuleyl ahayn;
2, aan-ionic-keeda waxay la noolaan kartaa tiro balaadhan oo ah polymers kale oo biyo-milmi leh, surfactants, cusbada, waa dhumuc weyn oo kolloidal ah oo ka kooban fiirsashada sare ee xalka elektrolytka;
3, awoodda haysashada biyuhu waxay laba jeer ka badan tahay methyl cellulose, oo leh hagaajinta socodka wanaagsan,
4, HEC awoodda kala firdhiso marka la barbar dhigo methyl cellulose iyo hydroxypropyl methyl cellulose awoodda kala firdhiso waa liidata, laakiin awoodda kolloid ilaalinta waa mid xooggan.
Afar, hydroxyethyl cellulose isticmaalaa: guud ahaan loo isticmaalo sida wakiilka dhumuc, wakiilka ilaalinta, koollada, xasilinta iyo diyaarinta emulsion, jelly, cadar, looshan, wakiilka nadiifinta indhaha, suppository iyo kiniinka lagu daro, sidoo kale loo isticmaalo sida jel hydrophilic, qalabka qalfoofka, diyaarinta qalfoofka. nooca diyaarinta sii daynta joogtada ah, waxa kale oo loo isticmaali karaa cuntada sidii xasiliye iyo hawlo kale.
Guryaha ugu muhiimsan qodista saliidda
HEC waxay ku jirtaa dhoobo la warshadeeyay oo la buuxiyay. Waxay ka caawisaa inay bixiso dhoobo adag oo hooseeya oo yaraynaysa dhaawaca soo gaadhay ceelka ceelka. Dhoobo ku dhumucday HEC si sahal ah ayay u hoos u dhigtaa hydrocarbons iyadoo aysiidh, enzymes, ama oksaydhiyeyaasha ay soo ceshan karaan saliid xadidan.
HEC waxay qaadi kartaa dhoobo iyo ciid ku jira dhoobada jajaban. Dheecaannadan waxa kale oo si fudud u dhimi kara asiidhyadan, enzymes-ka ama oksaydhiyeyaasha.
HEC waxay bixisaa dareere qodid oo adag oo hooseeya kuwaas oo siinaya awood weyn iyo xasillooni qodid wanaagsan. Sifooyinkeeda xakamaynta dareeraha waxaa loo isticmaali karaa qaababka dhagxaanta adag, iyo sidoo kale godadka ama qaababka shaleeska simbiriirixaya.
Hawlgallada sibidhka, HEC waxa ay yaraynaysaa is jiid-jiidka dareeraha sibidhka-cadaadiska ah, sidaas awgeed waxa ay yaraynaysaa burburka dhisme ee ay sababto lumista biyuhu.

Tilmaamaha waxqabadka
1.Iska caabin milix ah
HEC waxay ku xasiloon tahay xalalka cusbada ee aadka u urursan mana u qudhunto dawladaha ionic. Loo isticmaalo koronto-samaynta, waxay ka dhigi kartaa dusha sare ee dahaadhka mid dhammaystiran, oo dhalaalaya. Waxaa xusid mudan in lagu dabaqo rinjiga borate, silicate iyo karboonayt rinjiga cinjirka ah, wali wuxuu leeyahay viscosity aad u wanaagsan.
2.Hanti dhumuc leh
HEC waa dhumuc ku habboon dahaarka iyo waxyaalaha la isku qurxiyo. Codsiga dhabta ah, dhumucdeeda iyo hakinta, badbaadada, kala firdhisanaanta, haynta biyaha isku darka codsiga waxay soo saari doontaa saameyn aad u fiican.
3.Pseudoplastic
Pseudoplasticity waa hantida in viscosity ee xalku hoos u dhaco korodhka xawaaraha wareega. HEC oo ka kooban rinji cinjir ah waa sahlan tahay in lagu mariyo buraash ama rullaluistemadka waxayna kordhin kartaa jilicsanaanta dusha sare, taas oo sidoo kale kordhin karta waxtarka shaqada; Shaambooyinka hec-ku jira waa dareere iyo dhegdheg, si sahlan loo qasi karo si fududna waa loo kala firdhiyaa.
4.Haysashada biyaha
HEC waxay ka caawisaa inay qoyaanka nidaamka ku hayso xaalad ku habboon. Sababtoo ah qadar yar oo HEC ah oo ku jira xalka aqueous wuxuu gaari karaa saameyn wanaagsan oo biyaha lagu hayo, si nidaamku u yareeyo baahida biyaha inta lagu jiro diyaarinta. Haddii aan biyo la hayn iyo ku dhegganaansho la'aan, hoobiye sibidhku waxa uu yarayn doonaa xooggiisa iyo ku dhegganaanshaha, dhoobadu waxa ay sidoo kale yaraynaysaa caagga marka cadaadis gaar ah la saaro.
5.Mlaabta
Astaamaha samaynta xuubabka ee HEC waxaa loo isticmaali karaa warshado badan. Hawlgallada waraaqaha, ee lagu dahaadhay wakiilka glazing HEC, waxay ka hortagi kartaa dufanka dhexgalka, waxaana loo isticmaali karaa in lagu diyaariyo qaybaha kale ee xalalka waraaqaha; HEC waxay kordhisaa dabacsanaanta fiilooyinka inta lagu jiro habka tolida oo sidaas awgeed waxay yaraynaysaa dhaawaca farsamada iyaga. HEC waxay u shaqeysaa sidii filim ilaalin ku meel gaar ah inta lagu jiro cabbirka iyo rinjiyeynta dharka waxaana lagu dhaqi karaa dharka biyaha marka aan loo baahnayn ilaalinteeda.
Hagaha Codsiga ee Wershadaha Saliidda:
Loo isticmaalo sibidhka iyo qodista goobta saliidda
●Hydroxyethyl cellulose HEC waxa loo isticmaali karaa sidii dhumuc iyo sibidh wakiilka dareeraha faragelinta wanaagsan. Xalka nuxurka hoose ee go'an kaas oo gacan ka geysanaya bixinta caddayn, sidaas darteed si weyn u yareynaya burburka dhismaha ee ceelka. Dareeraha ku dhumucsan hydroxyethyl cellulose waxaa si fudud u burburiya acids, enzymes ama oksidants, taas oo si weyn u wanaajisa awoodda dib u soo kabashada hydrocarbons.
