Hydroxyethyl cellulose (HEC) yog ib qho uas tsis yog-ionic cellulose ether ua los ntawm ntuj polymer khoom cellulose los ntawm ib tug series ntawm etherification. Nws yog ib qho tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom dawb hmoov los yog granule, uas tuaj yeem yaj hauv dej txias los tsim cov kua nplaum pob tshab, thiab kev sib cais tsis cuam tshuam los ntawm tus nqi pH. Nws muaj thickening, khi, dispersing, emulsifying, zaj duab xis-forming, suspending, adsorbing, nto active, noo noo-retaining thiab ntsev-resistant zog. Siv dav hauv cov xim, kev tsim kho, textile, tshuaj niaj hnub, ntawv, roj drilling thiab lwm yam lag luam.
Mainsiv ntawmHydroxyethyl cellulose
1. Xim & Txheej
Cov xim pleev xim dej yog cov kua nplaum uas tsim los ntawm cov kuab tshuaj organic los yog dej raws li cov resin, los yog roj, los yog emulsion, nrog rau cov khoom siv ntxiv. Cov txheej txheem dej uas muaj kev ua tau zoo yuav tsum muaj kev ua haujlwm zoo, muaj zog zais zoo, muaj zog txheej adhesion, thiab kev tuav dej zoo; cellulose ether yog cov khoom siv zoo tshaj plaws los muab cov khoom no.
2. Kev tsim vaj tsev
Hauv kev lag luam kev tsim kho, HEC yog siv los ua cov khoom siv ntxiv rau cov khoom siv xws li cov ntaub ntawv phab ntsa, pob zeb (xws li asphalt), cov vuas pasted thiab cov ntaub ntawv caulking.
Cov khoom siv ntxiv tuaj yeem ua kom cov viscosity thiab thickening ntawm lub tsev cov ntaub ntawv, txhim kho adhesion, lubrication, thiab dej tuav, txhim khu lub flexural lub zog ntawm cov khoom los yog cov khoom, txhim kho shrinkage, thiab zam cov kab nrib pleb.
3. Textile
HEC-kho paj rwb, hluavtaws fibers los yog blends txhim kho lawv cov khoom xws li abrasion tsis kam, dyeability, hluav taws tsis kam thiab stain kuj, nrog rau kev txhim kho lawv lub cev stability (shrinkage) thiab durability, tshwj xeeb tshaj yog rau hluavtaws fibers, uas ua rau lawv breathable thiab zoo li qub. hluav taws xob.
4. Txhua hnub tshuaj
Cellulose ether yog ib qho tseem ceeb ntxiv hauv cov khoom siv tshuaj txhua hnub. Nws tuaj yeem tsis tsuas yog txhim kho cov viscosity ntawm cov kua los yog emulsion tshuaj pleev ib ce, tab sis kuj txhim kho dispersion thiab ua npuas ncauj stability.
5.Papermaking
Hauv daim teb ntawm papermaking, HEC tuaj yeem siv los ua tus neeg sawv cev sizing, ntxiv dag zog rau tus neeg sawv cev thiab ntawv, kev hloov kho zoo
6. Roj drilling
HEC feem ntau yog siv los ua cov thickening thiab stabilizing tus neeg sawv cev hauv cov txheej txheem kev kho roj. Nws yog ib tug zoo oilfield tshuaj. Nws tau dav siv hauv kev drilling, ua tiav zoo, cementing thiab lwm yam kev lag luam roj hauv txawv teb chaws hauv xyoo 1960.
7.Lwm daim ntawv thov
7.1 Kev ua liaj ua teb
Hydroxyethyl cellulose (HEC) tuaj yeem tshem tawm cov tshuaj lom zoo hauv cov tshuaj tsuag dej.
HEC tuaj yeem ua lub luag haujlwm ntawm adhering tshuaj lom rau nplooj hauv kev ua haujlwm txau; HEC tuaj yeem siv los ua cov thickener rau cov tshuaj tsuag emulsions kom txo tau cov tshuaj drift, yog li ua kom cov nyhuv ntawm foliar txau.
HEC kuj tuaj yeem siv los ua tus neeg ua yeeb yaj kiab ua yeeb yaj kiab hauv cov noob txheej txheej; raws li ib tug nplaum nyob rau hauv recycling ntawm luam yeeb nplooj.
7.2 Qhov hluav taws kub
Hydroxyethyl cellulose tuaj yeem siv los ua cov khoom siv ntxiv txhawm rau txhawm rau txhawm rau txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob, thiab tau siv dav hauv kev npaj cov hluav taws kub "thickeners"
7.3 Forging
Hydroxyethylcellulose tuaj yeem txhim kho lub zog ntub dej thiab shrinkability ntawm cement xuab zeb thiab sodium silicate xuab zeb tshuab.
7.4 Microscopy
Hydroxyethyl cellulose tuaj yeem siv rau hauv kev tsim cov yeeb yaj kiab thiab ua ib qho dispersant hauv kev tsim cov duab me me.
7.5 Yees duab
Thickener nyob rau hauv siab ntsev concentration kua siv rau ua zaj duab xis.
7.6 Fluorescent tube xim
Siv los ua ib daim ntawv khi thiab ruaj khov dispersant rau fluorescent tus neeg sawv cev hauv cov fluorescent raj txheej.
7.7 Electroplating thiab Electrolysis
Nws tuaj yeem tiv thaiv cov colloid los ntawm kev cuam tshuam ntawm electrolyte concentration; hydroxyethyl cellulose tuaj yeem txhawb nqa kev tso nyiaj tsis zoo hauv cadmium plating tov.
7.8 Ceramics
Nws tuaj yeem siv los tsim cov binders muaj zog rau ceramics.
7.9 kab
Cov tshuaj tiv thaiv dej tiv thaiv cov dej noo los ntawm kev nkag mus rau cov kab uas puas lawm.
