Cellulose ether yog ib qho kev kawm tseem ceeb ntawm cov ntaub ntawv polymer, siv rau hauv tshuaj, khoom noj, cov tshuaj pleev ib ce thiab lwm thaj teb. Nws cov ntawv thov hauv cov tshuaj pleev ib ce tsuas yog suav nrog cov khoom siv thickeners, cov yeeb yaj kiab sib ntxiv rau cov khoom npog lub cev, thiab lwm yam ntawm cov khoom lag luam, tab sis kuj txhim kho cov neeg siv kev paub. Kab lus no yuav tham txog daim ntawv thov ether ether hauv lub ntsej muag ntsej muag, tshwj xeeb yog yuav txo cov ntais ntawv thaum siv.
Nws yog qhov tsim nyog kom nkag siab txog qhov yooj yim muaj xws li thiab ua haujlwm ntawm lub ntsej muag ntsej muag. Lub ntsej muag ntsej muag feem ntau muaj ob ntu: cov khoom siv hauv paus thiab essence. Cov khoom siv hauv paus yog feem ntau cov ntaub qhwv, cov yeeb yaj kiab cellulose, cov khoom xyaw ua ke yog qhov teeb meem uas nquag ntsib thaum siv ntsej muag ntsej muag. Qhov kev xav no tsis yog cuam tshuam rau kev siv kev paub, tab sis kuj yuav cuam tshuam rau qhov nqus ntawm cov ntsej muag ntsej muag ntsej muag.
Cellulose ether yog chav ua haujlwm tau los ntawm kev siv tshuaj lom neeg muaj qhov ruaj khov, thiab nws cov tshuaj lom neeg muaj qhov ruaj khov (MC), thiab nws tsis yooj yim ua rau cov tawv nqaij ua xua. Yog li ntawd, nws tau siv dav hauv cov tshuaj pleev ib ce.
Daim ntawv thov cellulose ether hauv cov ntsej muag ntsej muag feem ntau txo cov nplaum nplaum los ntawm cov hauv qab no:
1. Txhim kho cov rheology ntawm essence
Cov rheology ntawm cov essence, uas yog, lub peev xwm deformation muaj peev xwm ntawm cov kua, yog qhov tseem ceeb cuam tshuam rau cov neeg siv kev paub. Cellulose ether tuaj yeem hloov lub viscosity ntawm essence, ua rau nws yooj yim rau kev thov thiab nqus. Ntxiv ib qho kev tsim nyog ether ether tuaj yeem ua rau daim ntawv qhia txog cov tawv nqaij nyias nyias muaj nyias moisturize yam tsis muaj qhov zoo li lo nplaum.
2. Txhim kho qhov kev tawm tsam ntawm cov essence
Cellulose ether muaj zoo dispersibility thiab tuaj yeem loj hlob ntau cov essence kom tsis txhob muaj nag lossis daus thiab stratification ntawm cov khoom xyaw. Cov ris tsho sib kis tau ua rau cov essence ntau dua faib ntawm lub ntsej muag zoo, thiab nws tsis yooj yim los tsim cov chaw siab hauv zos lub sijhawm siv, yog li txo cov ntawv nplaum.
3. Txhim khu qhov muaj peev xwm nqus tau ntawm daim tawv nqaij
Cov yeeb yaj kiab nyias muaj los ntawm cellulose ether rau ntawm daim tawv nqaij muaj cov pa tawv, uas pab txhim kho cov pa tawv nqaij ntawm cov khoom xyaw ua haujlwm ntawm cov essence. Thaum daim tawv nqaij tuaj yeem nqus cov khoom noj kom sai li ntawm cov khoom noj, cov khoom seem ntawm cov tawv nqaij yuav qis zuj zus, yog li txo qhov kev xav nplaum.
4. Muab cov nyhuv uas tsim nyog
Cellulose ether nws tau muaj qee cov nyhuv noo, uas tuaj yeem kaw hauv noo noo thiab tiv thaiv cov tawv nqaij noo ploj. Hauv lub ntsej muag cuav, ntxiv rau ntawm cellulose ether tuaj yeem txo tus nqi ntawm lwm cov ha-viscosity moisturizers, yog li txo lub viscosity ntawm lub ntsiab lus raws li ib tug tag nrho.
5. Txav cov txheej txheem essence
Lub ntsej muag ntsej muag ntsej muag feem ntau muaj ntau yam khoom xyaw nquag, uas yuav cuam tshuam nrog txhua lwm yam thiab cuam tshuam rau kev ruaj ntseg ntawm cov khoom. Cellulose ether tuaj yeem siv los ua cov stabilizer kom pab tswj hwm qhov chaw ruaj khov los ntawm kev hloov pauv los ntawm cov khoom xyaw tsis ruaj khov.
Daim ntawv thov ntawm cellulose ether hauv cov ntsej muag ntsej muag tuaj yeem txhim kho lub cev lub cev ntawm cov khoom lag luam, tshwj xeeb tshaj yog txo cov khoom zoo thaum siv. Cellulose ether coj cov neeg siv cov khoom siv zoo dua rau cov khoom npog ntsej muag los ntawm kev txhim kho daim npog ntsej muag, txhim kho cov nyhuv uas tsim nyog thiab tso hluav taws xob ruaj khov. Nyob rau tib lub sijhawm, lub keeb kwm ntuj thiab zoo biocompatitomity ntawm cellulpose ntawm cellulose kev cia siab hauv kev lag luam tshuaj pleev ib ce.
Nrog kev nce qib nruam ntawm cov tshuaj pleev ib ce ntawm cov neeg siv khoom thiab kev txhim kho ntawm cov khoom siv ntawm cellulose yuav sib thooj ntxiv. Nyob rau hauv lub neej yav tom ntej, ntau tshaj cellulose ether derivatives thiab tsim cov thev naus laus zis, nqa ntau cov kev paub ntxiv rau cov khoom npog ntsej muag.
