Hydroxyethyl Cellulose siv rau dab tsi?

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.

Cov chaw siv tseem ceeb:

1. Xim: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.Ckev qhia:Hauv kev lag luam kev tsim kho, HEC yog siv los ua cov khoom siv ntxiv rau cov ntaub ntawv xws li cov ntaub ntawv phab ntsa, pob zeb (xws li asphalt), cov vuas luaj thiab cov ntaub ntawv caulking, uas tuaj yeem ua kom cov viscosity thiab thicken ntawm cov ntaub ntawv hauv tsev, txhim kho adhesion, lubrication, thiab dej. khaws cia. Txhim khu lub zog flexural ntawm cov khoom lossis cov khoom sib txuas, txhim kho shrinkage, thiab zam cov kab nrib pleb.

3. Ttxawv teb chaws: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.Daily 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. Ntawv:Hauv kev tsim daim ntawv, HEC tuaj yeem siv los ua tus neeg sawv cev sizing, ntxiv dag zog rau tus neeg sawv cev thiab hloov daim ntawv.

6.o ibnws 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.

Lwm yam kev thov:

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 binder nyob rau hauv recycling ntawm luam yeeb nplooj. Hydroxyethyl cellulose tuaj yeem siv los ua cov khoom siv ntxiv los ua kom muaj kev ua haujlwm ntawm cov khoom siv hluav taws xob, thiab tau siv dav hauv kev npaj cov hluav taws kub "thickeners". Hydroxyethyl cellulose tuaj yeem txhim kho lub zog ntub dej thiab shrinkability ntawm cement xuab zeb thiab sodium silicate xuab zeb tshuab.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. Thickener hauv cov kua dej uas muaj ntsev ntau siv hauv kev ua yeeb yaj kiab. Siv los ua ib daim ntawv khi thiab ruaj khov dispersant rau fluorescent tus neeg sawv cev hauv cov fluorescent raj txheej. 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. Nws tuaj yeem siv los tsim cov binders muaj zog rau ceramics. Cov tshuaj tiv thaiv dej tiv thaiv cov dej noo los ntawm kev nkag mus rau cov kab uas puas lawm.
