Hydroxyethyl cellulose (HEC)yog cov dej nonionic-soluble polymer dav siv nyob rau hauv ntau yam kev lag luam, nrog kev faib tawm zoo, emulsification, zaj duab xis, ua yeeb yaj kiab thiab cov nplaum nplaum. Vim nws cov tshuaj ruaj khov zoo thiab biocompatibility, HEC muaj cov ntawv thov tseem ceeb, siv tshuaj, cov tshuaj txhua hnub, tshuaj noj, tshuaj thiab khoom noj.
1. Kev lag luam txheej txheem
HEC tau dav siv los ua cov tuab dua, stabilizer thiab cov yeeb yaj kiab-ua yeeb yam hauv cov txheej txheem kev lag luam.
Thickening cov nyhuv: HEC tuaj yeem ua kom muaj zog ua rau lub viscosity ntawm txheej, yog li nws muaj kev tsim kho zoo thiab thixotrotropy thaum lub sij hawm tsim kho, thiab tsis txhob txheej ntawm sagging ntawm qhov chaw ntsug.
Dispersion thiab stabilization: HEC tuaj yeem txhawb kev sib cais ntawm cov pigments thiab fillers, thiab tswj hwm qhov ruaj khov ntawm cov txheej txheem thaum lub sijhawm nres tsheb lossis nag lossis daus.
Txhim kho kev tsim kho kev tsim kho: hauv cov xim pleev xim rau looj thiab cov tshuaj txhuam hniav kom zoo ntxiv rau kev txhuam hniav, thiab muab cov khoom sib txig thiab txig sib xyaw thiab cov npoo ua tiav.
2. Kev lag luam kev tsim kho
Hauv kev tsim kho, HEC feem ntau yog siv nyob rau hauv cov khoom xws li cement hmoov thiab cov hmoov av nplaum kom ua si, dej tuav thiab txhim kho kev tsim kho.
Dej Tuav Tseg Kev Ua Tau Zoo: HEC muaj peev xwm txhim kho cov dej tshuaj khib nyiab thiab ntev dua cov tshuaj tiv thaiv kev ua haujlwm, yog li kev txhim kho lub zog thiab kav ntev ntawm cov khoom siv.
Txhim kho kev tsim kho: Hauv cov hmoov nplaum thiab cov nyhuv pobzeb, lubricating nyhuv ntawm HEC ua rau kev tsim kho smoother thiab tiv thaiv kev tawg thiab tev ntawm cov txheej.
Los tiv thaiv cov ntaub ntawv: HEC muab cov ntaub ntawv tsim lub tsev zoo los tiv thaiv cov khoom kom ntseeg tau tias cov ntaub ntawv tom qab kev tsim kho cov duab zoo tagnrho.
3. Txhua Yam Kev Lag Luam
HEC tau dav siv los ua cov tuab thiab tawv nqaij thiab cov tshuaj ntxuav txhua hnub, tshuaj ntxuav ntxhua khaub ncaws thiab cov khoom siv da dej thiab cov khoom siv tu tawv nqaij.
Thickening thiab ruaj khov: Hec Ua raws li tus neeg tswj hwm visculator hauv cov qauv viscososter thiab txhim kho cov neeg siv kev paub.
Emulsification thiab raug ncua: Hauv cov khoom saib xyuas cov tawv nqaij thiab tiv thaiv kev tawm tsam, thaum uas cov chaw pearles lossis cov tsw qab.
Kev mob Mees: Txij li HEC tsis yog-ua kom tawv nqaij, nws yog qhov tshwj xeeb rau kev siv hauv cov khoom menyuam thiab cov khoom lag luam rau rhiab tawv.
4. Cov roj rho kev lag luam
Nyob rau hauv cov roj kev lag luam, HEC feem ntau yog siv los ua cov thickener thiab kua poob reducer rau drilling kua thiab ua tiav cov kua.
Thickening cov nyhuv: HEC nce lub viscosity ntawm drilling kua, yog li txhim kho lub peev xwm nqa cuttings thiab ua kom txoj kev huv.
Kev txo cov kua dej txo qis: HEC tuaj yeem txo cov dej nkag rau ntawm cov kua dej drilling, tiv thaiv cov roj thiab roj ua ke, thiab tiv thaiv kom tsis txhob muaj roj collapse.
Ib puag ncig cov phooj ywg: lub biodegradity thiab tsis muaj tshuaj lom ntawm Hec tau raws li cov kev xav tau ntawm kev txhim kho cov roj ntsuab kev lag luam.
5. Kws Tshuaj Kho Mob
Hauv lub chaw muag tshuaj, HEC yog siv los ua cov tuab, cov nplaum thiab cov khoom sib xyaw ua ke rau kev tswj cov tshuaj.
Thickening thiab zaj duab xis-tsim: HEC yog siv nyob rau hauv lub sij hawm lub sij hawm ntev lub sij hawm ntawm cov yeeb yaj kiab ntawm lub qhov muag thiab txhim kho kev ua tau zoo ntawm cov tshuaj.
Kev Tso Tawm Tso Tawm: Hauv cov ntsiav tshuaj uas muaj cov ntsiav tshuaj-tso tawm los ntawm HEC tuaj yeem tswj cov tshuaj tso tawm Yeeb Tshuaj, txhim kho kev ua tau zoo thiab tus neeg mob ua raws.
Biocompatibility: HEC cov khoom tsis muaj tshuaj lom thiab tsis muaj kev sib zog ua kom nws haum rau ntau yam tshuaj ntau npaum li cas, suav nrog kev npaj thiab tso kua.
6. Kev lag luam khoom noj
Hauv kev lag luam khoom noj khoom haus, HEC tau dav siv los ua tuab, emulsifier thiab stabilizer nyob rau hauv cov khoom noj siv mis, dej haus, kua txiv thiab lwm yam khoom.
Thickening thiab kev ncua: HEC ua rau lub kaw lus ntau dua qub hauv cov dej haus thiab cov kua ntses, txhim kho cov saj thiab tsos thiab cov khoom lag luam.
Stability: Hec txwv tsis pub stratification ntawm emulsions lossis raug ncua thiab nce lub txee lub neej ntawm cov khoom lag luam.
Kev Nyab Xeeb: HEC muaj kev nyab xeeb thiab tsis muaj tshuaj lom tau raws li cov kev yuav tsum tau ua ntawm cov khoom noj ntxiv cov zaub mov.
7. Lwm cov teb
Tus paKuj tseem siv rau hauv cov ntawv thov, Textile, Luam Ntawv thiab cov kev lag luam yam khoom siv tshuaj tua kab. Piv txwv li, nws yog siv los ua tus neeg sawv cev nto si hauv papermaking los txhim kho lub zog thiab ci ntawm daim ntawv; raws li cov slurry hauv textile luam ntawv thiab zowing kom txhim kho qhov dyeing uniformity ntawm cov ntaub; Thiab siv rau thickening thiab dispersing kev ncua nyob rau hauv cov ua kab tsuag tshuaj tua kab.
Vim nws cov kev ua tau zoo heev thiab kev siv dav, hydroxyethyl cellulose plays lub luag haujlwm tsis tseem ceeb hauv ntau qhov kev lag luam. Nyob rau yav tom ntej, raws li qhov kev thov rau cov khoom ntsuab thiab ib puag ncig cov cheeb tsam thiab kev txhim kho kev txhim kho hauv ntau lub sijhawm ntawm ntau yam kev lag luam.
