HEC ee Rinjiga

HEC waxay u gaaban tahay hydroxyethyl Cellulose. Hydroxyethyl celluloseHECwaa jaale cad ama cirro leh, aan dhadhamin, aan sun ahayn, fibros ama budo leh oo adag oo lagu diyaariyey etherification of cellulose alkaline iyo ethylene oxide (ama chloroethanol). Waa eter cellulose milmaya aan ionic ahayn. Sida surfactant-aan-ionic ah, marka lagu daro dhumucyada, hakinta, isku xidhka, sabaynta, samaynta filimada, kala firdhinta, haynta biyaha iyo ilaalinta.

Kiimiko sifooyinka:

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 waxay leedahay awoodda kala firdhinta ugu xun marka la barbar dhigo methyl cellulose la aqoonsan yahay iyo hydroxypropyl methyl cellulose, laakiin awoodda ilaalinta kolloid ee ugu xooggan.

Sidaa darteed, hydroxyethyl cellulose waxaa si weyn loogu isticmaalaa ka faa'iidaysiga batroolka, daahan, dhismaha, daawada iyo cuntada, dunta, waraaqaha samaynta iyo falcelinta polymer polymerization iyo beeraha kale.

Guryaha ugu muhiimsan eeHECloogu talagalay rinjiga cinjirka

1.Hanti dhumuc leh

Hydroxyethyl cellulose (HEC) waa dhumuc ku habboon dahaarka iyo waxyaalaha la isku qurxiyo. Codsiga wax ku oolka ah, isku darka dhumucdeeda oo leh ganaax, badbaado, kala firdhisanaan iyo haynta biyaha ayaa soo saari doona natiijooyin fiican.

1. 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.

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 la isticmaalo rinjiga borate, silicate iyo karbonat rinjiga cinjirka ah, wali wuxuu leeyahay viscosity aad u wanaagsan.

4.A membranous

Astaamaha samaynta xuubabka ee HEC waxaa loo isticmaali karaa warshado badan. Hawlgallada waraaqaha, ee lagu dahaadhay wakiilka glazing HEC, ayaa ka hortagi kara 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.

1. Haysashada biyaha

HEC waxay 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 ee 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.

Habka codsiga ee hydroxyethyl cellulose HECrinjiga cinjirka

1. Si toos ah ugu dar marka aad shiidi karto midabka: habkani waa kan ugu fudud, wakhtiga la isticmaalayna waa gaaban yahay. Tillaabooyinka faahfaahsan waa sida soo socota:

(1) Ku dar biyo sifaysan oo ku habboon VAT ee kicinta sare ee goynta (guud ahaan, ethylene glycol, wakiilka qoynta iyo wakiilka samaynta filimada ayaa lagu daray wakhtigan)

(2) Ku billow inaad ku walaaqdo xawaare hooseeya oo si tartiib ah ugu dar hydroxyethyl cellulose

(3) Sii wad inaad walaaqdo ilaa dhammaan qaybaha ay qooyaan

(4) ku dar caariyaysiyaha caariyaysiga, PH nidaamiyaha, iwm

(5) Ku walaaq ilaa dhammaan cellulose hydroxyethyl ay si buuxda u milmaan (viskosity ee xalka ayaa si weyn u kordhay) ka hor intaadan ku darin qaybaha kale ee caanaha, oo shiid ilaa uu noqdo rinji.

2 qalabaysan dareeraha hooyada sugitaanka: habkan marka hore waxaa lagu qalabeeyaa fiirsashada sare ee dareeraha hooyada, ka dibna ku dar rinjiga cinjirka ah, faa'iidada habkan waa dabacsanaan weyn, si toos ah loogu dari karaa rinji la dhammeeyey, laakiin waa inay ahaataa kayd ku habboon. Tallaabooyinka iyo hababku waxay la mid yihiin tillaabooyinka (1) - (4) ee Habka 1, marka laga reebo in kicinta sare ee goynta aan loo baahnayn oo kaliya qaar ka mid ah kicinta oo leh awood ku filan si ay u ilaaliso fiilooyinka hydroxyethyl si siman u kala firirsan xalka ayaa ku filan. Sii wad walaaq ilaa uu si buuxda u milmo xal qaro weyn. Ogsoonow in caariyaysiga caariyaysigu ay tahay in lagu daro khamriga hooyada sida ugu dhakhsaha badan.

3. Boorash sida phenology: Maadaama dareerayaasha organic ay yihiin dareerayaasha xun ee hydroxyethyl cellulose, dareerayaashan organic waxaa lagu qalabayn karaa boorash. Walxaha ugu badan ee la isticmaalo sida ethylene glycol, propylene glycol, iyo walxaha samaynta filimada (sida hexadecanol ama diethylene glycol butyl acetate), biyaha barafku sidoo kale waa dareere liidata, sidaas awgeed biyaha barafka waxaa badanaa lagu isticmaalaa dareerayaasha organic ee boorashka.

Gruel - sida hydroxyethyl cellulose si toos ah ayaa loogu dari karaa rinjiga. Hydroxyethyl cellulose ayaa lagu dheregsan yahay qaab boorash. Ka dib marka lagu daro lacquer, isla markiiba milaan oo saameyn dhumuc leh. Ka dib markaad ku darto, sii wad inaad walaaqdo ilaa hydroxyethyl cellulose si buuxda u milmay iyo labbiska. Boorashka caadiga ah waxaa la sameeyaa iyadoo lagu qaso lix qaybood oo dareere organic ama biyo baraf ah qayb ka mid ah hydroxyethyl cellulose. Qiyaastii 5-30 daqiiqo ka dib, hydroxyethyl cellulose hydrolyzes oo si muuqata u kaca. Xilliga xagaaga, qoyaanka biyuhu aad buu u sarreeyaa si loogu isticmaalo boorash.

4.Arrimaha u baahan feejignaan marka la qalabeynayo khamriga hooyada hydroxyethyl cellulose

Maadaama hydroxyethyl cellulose ay tahay budo granular ah oo la daweeyay, way fududahay in la xakameeyo oo lagu milmo biyaha iyadoo la raacayo taxaddarrada soo socda.

Ogaysiis

4.1 Kahor iyo ka dib marka lagu daro hydroxyethyl cellulose, waa in si joogto ah loo walaaqaa ilaa xalku uu yahay mid hufan oo cad.

4.2. Si tartiib ah ugu miir hydroxyethyl cellulose haanta isku darka. Ha ku darin haanta isku dhafka ah tiro badan ama si toos ah ha u gelin cufnaanta ama spherical hydroxyethyl cellulose.

4.Heerkulka biyaha 3 iyo qiimaha pH ee biyuhu waxay leeyihiin xidhiidh cad oo la xidhiidha milanka hydroxyethyl cellulose, markaa fiiro gaar ah waa in la siiyaa.

4.4Ha ku darin qaar ka mid ah walaxda aasaasiga ah isku dhafka ka hor inta aan budada hydroxyethyl cellulose lagu qooyay biyo. Kor u qaadista pH ka dib marka la qooyo waxay caawisaa milanka.

4.5 Inta suurtogalka ah, goor hore oo lagu daro caariyaysiyaha.

4.6 Marka la isticmaalayo hydroxyethyl cellulose viscosity sare, fiirsashada khamriga hooyadu waa inuusan ka badnaan 2.5-3% (miisaan ahaan), haddii kale khamriga hooyadu waa adag tahay in la shaqeeyo.

Waxyaabaha saameeya viscosity ee rinjiga cinjirka

1 Inta badan hawo-xumo hadhaaga ah ee rinjiga, ayaa kor u kacaya viscosity.

2 Xaddiga firfircooni iyo biyaha ku jira caanaha rinjiga ma yihiin kuwo joogto ah?

3 ee isku dhafka cinjirka, hadhaaga okssaydhka ka kooban ee qaddarka.

4. Qiyaasta dhumucyada kale ee dabiiciga ah ee caanaha rinjiga iyo saamiga qiyaasta lehHEChydroxyethyl cellulose.)

5 habka samaynta rinjiga, nidaamka tallaabooyinka lagu daro dhumucdiisuna waa ku habboon yahay.
