Waa maxay Hydroxyethyl cellulose?

Hydroxyethyl cellulose (HEC) waa caddaan ama huruud khafiif ah, ur aan lahayn, fibros aan sun ahayn ama adag budo ah, oo lagu diyaariyey falcelinta etherification ee cellulose alkaline iyo ethylene oxide (ama chlorohydrin).
1. Tilmaamaha
1.1 ayaa si toos ah loogu daray wakhtiga wax soo saarka

1. Ku dar biyo nadiif ah baaldi weyn oo ku qalabaysan qasiyaha xiirid sare.

2. Bilow inaad si joogto ah u walaaq xawaare hoose oo si tartiib ah u kala miir hydroxyethyl cellulose si siman xalka.

3. Sii wad walaaq ilaa dhammaan qaybaha ay qooyaan.

4. Ka dibna ku dar wakiilka antifungal, waxyaabaha alkaline-ka ah sida midabada, kala firdhinta qalabka, biyaha ammonia.

5. Walaaq ilaa dhammaan cellulose hydroxyethyl ay si buuxda u milmaan (viskosity ee xalku si aad ah ayuu u kordhiyaa) ka hor intaadan ku darin qaybaha kale ee caanaha, oo shiid ilaa alaabta la dhammeeyo.

1.2 Lagu diyaariyey khamriga hooyada

Habkani waa in marka hore la diyaariyo khamriga hooyada oo leh feejignaan sare, ka dibna lagu daro rinjiga cinjirka. Faa'iidada habkani waa in uu leeyahay dabacsanaan weyn oo si toos ah loogu dari karo rinjiga la dhammeeyey, laakiin waa in si habboon loo kaydiyaa. Tallaabooyinka waxay la mid yihiin Tallaabooyinka 1-4 ee Habka 1, farqiga ayaa ah in aan loo baahnayn in la kiciyo ilaa ay si buuxda u milmayso xal viscous ah.

2.Boorash for phenology
Maadaama dareerayaasha organic yihiin dareerayaal liidatahydroxyethyl cellulose, kuwaas oo dareere organic waxaa loo isticmaali karaa si ay u diyaariyaan boorashka. Walxaha dabiiciga ah ee inta badan la isticmaalo waa dareerayaasha dabiiciga ah sida ethylene glycol, propylene glycol iyo filim hore (sida ethylene glycol ama diethylene glycol butyl acetate) ee naqshadaynta rinjiga. Biyaha barafka sidoo kale waa dareere liidata, sidaas darteed biyaha barafka waxaa badanaa la isticmaalaa dareerayaasha organic si loogu diyaariyo boorash. Hydroxyethyl cellulose ee boorashka si toos ah ayaa loogu dari karaa rinjiga, iyo hydroxyethyl cellulose waa la kala qaybiyay oo bararay boorashka. Marka lagu daro rinjiga, isla markiiba wuu milaan oo wuxuu u dhaqmaa sidii dhumuc. Ka dib markaad ku darto, sii walaaq ilaa hydroxyethyl cellulose si buuxda u milmay oo lebbiska ah. Guud ahaan, boorashka waxaa la sameeyaa iyadoo lagu qaso lix qaybood oo dareere organic ah ama biyaha barafka iyo qayb ka mid ah hydroxyethyl cellulose. Qiyaastii 6-30 daqiiqo ka dib, hydroxyethyl cellulose waa la nadiifin doonaa oo si cad u barari doonaa. Xilliga xagaaga, heerkulka biyuhu guud ahaan aad buu u sarreeyaa, markaa kuma habboona in la isticmaalo boorash.
3.Awoodda codsiga

Hydroxyethyl cellulose Waxaa loo isticmaalaa sida xabagta, surfactants, wakiilada kolloidal ilaalinta, kala firdhiyaa, iwm.
Waxay leedahay codsiyo kala duwan oo kala duwan oo ku saabsan rinjiga, rinjiga, fiber-ka, midabaynta, samaynta waraaqaha, waxyaalaha la isku qurxiyo, sunta cayayaanka, farsamaynta macdanta, wakiilada soo kabashada saliidda, iyo daawada.

1. Hydroxyethyl cellulose waxaa guud ahaan loo isticmaalaa sida dhumucdiisuna, wakiilka ilaalinta, xabagta, stabilizer iyo lagu daro diyaarinta emulsion, jelly, cadar, looshan, nadiifinta indhaha, suppository iyo kiniinka, iyo sidoo kale loo isticmaalo sida gel hydrophilic iyo Qalfoofka Materials, diyaarinta ee diyaarinta sii-deynta joogtada ah ee nooca-matrix-ka ah, waxaana sidoo kale loo isticmaali karaa xasiliye cuntada.

2. Hydroxyethyl cellulose Waxa loo isticmaalaa sidii wakiilka cabbirka ee warshadaha dunta, iyo sidii wakiil caawiye ee isku xidhka, dhumucyada, emulsifying, iyo xasilinta qaybaha elaktrooniga iyo warshadaha iftiinka.

3. Waxa loo istcimaalaa dhumucdiye iyo luminta dareeraha dareeraha qodista biyaha ku salaysan iyo dareeraha dhamaystirka, saamaynta dhumucduna waxay ku caddahay dareeraha qodista brine. Waxa kale oo loo isticmaali karaa dhimis luminta dareeraha sibidhka ceelka saliidda. Waxa lagu xidhi karaa ion bir polyvalent si loo sameeyo jel.

4. Badeecada cellulose Hydroxyethyl waxaa loo isticmaalaa sida kala firdhiso loogu talagalay polymerization ee dareeraha jelka biyaha ku salaysan ee batroolka, polystyrene iyo chloride polyvinyl, iwm. iyadoo la jebinayo. Waxa kale oo loo isticmaali karaa sidii dhumucda emulsion ee warshadaha rinjiga, hygrostat ee warshadaha elektiroonigga ah, xinjirowga lidka ku ah sibidhka iyo wakiilka qoyaanka ilaalinta ee warshadaha dhismaha. Dhaldhalaalka warshadaha dhoobada iyo dawada cadayga. Waxa kale oo si weyn loogu isticmaalaa daabacaadda iyo midabaynta, dunta, waraaqaha samaynta, daawada, nadaafadda, cuntada, sigaarka, sunta cayayaanka iyo walxaha dab-damiska.

5. Sida surfactant, wakiilka ilaalinta kolloidal, emulsification stabilizer for vinyl chloride, vinyl acetate iyo emulsions kale, iyo sidoo kale tackifier cinjirka, kala firdhiso, kala firdhiso stabilizer, iwm. , iwm. Waxa kale oo ay leedahay adeegsi badan oo dhinaca sahaminta shidaalka iyo warshadaha.

6. Hydroxyethyl cellulose waxa uu leeyahay dusha firfircoon, dhumucdiisuna, laalid, xidhitaan, emulsifying, film-samaynta, kala firdhiyey, biyo-hayntiisa iyo hawlaha ilaalinta ee daawooyinka adag iyo diyaarinta dareere ah.

7. Waxa loo istcimaalaa kala firdhiso polymeric ka faa'iidaysiga dareeraha jelka biyaha ku salaysan ee batroolka, chloride polyvinyl iyo polystyrene. Waxa kale oo loo isticmaali karaa sidii dhumuc emulsion ah warshadaha rinjiga, xinjirowga lidka ku ah sibidhka iyo wakiilka qoyaanka ilaalinta ee warshadaha dhismaha, wakiilka dhaldhalaalka iyo koollada cadayga ee warshadaha dhoobada. Waxa kale oo si weyn looga isticmaalaa goobaha warshadaha sida daabacaadda iyo rinjiyeynta, dunta, waraaqaha, dawooyinka, nadaafadda, cuntada, sigaarka iyo sunta cayayaanka.
