Txhim kho kev tsim kho: Hauv cov xim latex thiab cov xim dej, HEC tuaj yeem txhim kho kev tsim kho ntawm txhuam, dov thiab tshuaj tsuag, thiab txhim kho cov yeeb yaj kiab tsim thiab ua kom tiav.
2. Kev tsim kho kev lag luam
Hauv kev tsim kho, HEC feem ntau yog siv rau hauv cov khoom xws li cement mortar, putty hmoov thiab pobzeb nplaum los ua lub luag haujlwm ntawm thickening, dej tuav thiab txhim kho kev tsim kho.
Kev tuav dej ua haujlwm: HEC tuaj yeem txhim kho cov dej tuav tus nqi ntawm cov tshuaj khib nyiab thiab ua kom lub sijhawm hydration cov tshuaj tiv thaiv, yog li txhim kho lub zog thiab ruaj khov ntawm cov khoom.
Txhim kho kev tsim kho: Hauv cov hmoov putty thiab pobzeb nplaum, cov nyhuv lubricating ntawm HEC ua rau kev tsim kho kom zoo dua qub thiab tiv thaiv kev tawg thiab tev ntawm txheej.
Los tiv thaiv sagging: HEC muab cov khoom siv hauv tsev zoo los tiv thaiv sagging kom ntseeg tau tias cov ntaub ntawv tom qab kev tsim kho kom zoo zoo.
3. Kev lag luam tshuaj txhua hnub
HEC yog dav siv los ua cov thickener thiab stabilizer nyob rau hauv cov tshuaj niaj hnub, nrog rau cov tshuaj detergents, tshuaj zawv plaub hau, da dej gels thiab cov khoom tu tawv nqaij.
Thickening thiab stabilization: HEC ua raws li viscosity regulator nyob rau hauv cov mis, muab cov khoom zoo tagnrho rheological zog thiab txhim kho cov neeg siv kev paub.
Emulsification thiab suspension: Hauv cov khoom tu tawv nqaij thiab cov khoom siv hauv chav dej, HEC tuaj yeem ua kom ruaj khov ntawm emulsified system thiab tiv thaiv stratification, thaum tshem tawm cov khoom siv xws li pearlescent agents lossis cov khoom siv.
Mildness: Txij li HEC tsis ua rau tawv nqaij, tshwj xeeb tshaj yog siv rau hauv cov khoom me nyuam thiab cov khoom siv rau cov tawv nqaij rhiab heev.
4. Roj extraction kev lag luam
Hauv kev lag luam roj, HEC feem ntau yog siv los ua cov thickener thiab kua poob reducer rau drilling kua thiab ua tiav kua.
Thickening nyhuv: HEC ua kom cov viscosity ntawm cov dej drilling, yog li txhim kho lub peev xwm nqa cov txiav thiab ua kom lub qhov dej huv.
Cov kua dej txo qhov ua tau zoo: HEC tuaj yeem txo cov dej nkag ntawm cov kua dej drilling, tiv thaiv cov roj thiab roj txheej, thiab tiv thaiv kom tsis txhob muaj dej tawg.
Environmental friendliness: Lub biodegradability thiab non-toxicity ntawm HEC ua tau raws li cov kev xav tau ntawm kev loj hlob ntawm kev lag luam roj ntsuab.
5. Kev lag luam kws tshuaj
Hauv kev lag luam tshuaj, HEC yog siv los ua cov thickener, nplaum thiab cov khoom siv matrix rau kev tswj cov tshuaj.
Thickening thiab film-forming: HEC yog siv rau hauv qhov muag tee kom ntev lub sij hawm nyob rau hauv cov tshuaj tov nyob rau saum npoo ntawm lub qhov muag thiab txhim khu kev ua tau zoo ntawm cov tshuaj.
Kev tso tawm muaj nuj nqi: Hauv cov ntsiav tshuaj thiab cov tshuaj ntsiav uas tau tso tawm, cov gel network tsim los ntawm HEC tuaj yeem tswj cov tshuaj tso tawm tus nqi, txhim kho kev ua tau zoo thiab kev ua raws li tus neeg mob.
Biocompatibility: HEC cov khoom tsis muaj tshuaj lom thiab tsis ua rau khaus ua rau nws haum rau ntau hom tshuaj, suav nrog tshuaj pleev thiab qhov ncauj npaj.
6. Kev lag luam zaub mov
Hauv kev lag luam zaub mov, HEC yog dav siv los ua cov thickener, emulsifier thiab stabilizer hauv cov khoom noj siv mis, dej haus, kua ntses thiab lwm yam khoom.
Thickening thiab suspension: HEC ua rau lub kaw lus zoo sib xws hauv cov dej haus thiab cov kua ntses, txhim kho saj thiab zoo li ntawm cov khoom.
Kev ruaj ntseg: HEC tiv thaiv cov stratification ntawm emulsions los yog ncua kev kawm ntawv thiab ua rau kom lub txee lub neej ntawm cov khoom.
Kev Nyab Xeeb: HEC muaj kev nyab xeeb siab thiab tsis muaj tshuaj lom neeg ua tau raws li cov kev cai nruj ntawm cov khoom noj ntxiv.
7. Lwm qhov chaw
HECNws kuj tseem siv rau hauv kev lag luam papermaking, textile, luam ntawv thiab tshuaj tua kab. Piv txwv li, nws yog siv los ua tus neeg saib xyuas qhov chaw nyob rau hauv papermaking los txhim kho lub zog thiab gloss ntawm daim ntawv; raws li slurry hauv textile printing thiab dyeing los txhim kho cov dyeing uniformity ntawm fabrics; thiab siv rau thickening thiab dispersing suspensions nyob rau hauv cov tshuaj tua kab formulations.
Vim nws cov kev ua tau zoo heev thiab kev siv dav, hydroxyethyl cellulose plays lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam. Nyob rau hauv lub neej yav tom ntej, raws li qhov kev thov rau ntsuab thiab ib puag ncig tus phooj ywg cov ntaub ntawv tseem loj hlob tuaj, HEC daim ntawv thov cov cheeb tsam thiab kev loj hlob technology yuav coj mus rau hauv ntau lub cib fim thiab muab kev pab txhawb rau lub sustainable kev loj hlob ntawm ntau yam industries.
