Taw qhia rau hydroxyethylcellulose (HEC)
Hydroxyethylcellose yog qhov siv tshuaj hloov kho cellulose polymer muab tau los ntawm cellulose los ntawm cov txheej txheem ntawm etherification. Nws yog ib qho siv nyob rau hauv ntau yam kev lag luam, suav nrog cov tshuaj, tshuaj pleev ib ce, thiab khoom noj. Hauv cov lag luam no, HEC pabcuam feem ntau yog lub thickening, thiab stabilizing tus neeg sawv cev vim nws cov dej tuav thiab ua yeeb yaj kiab ua yeeb yam.
Kev siv cov kev siv ntawm hydroxyethylcellulose
Cov tshuaj pleev ib ce: HEC yog ib qho khoom siv uas nquag muaj nyob hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej xws li tshuaj zawv plaub hau xws li tshuaj zawv plaub hau xws li tshuaj zawv plaub hau, cov khoom noj, pleev xim, tshuaj pleev, tshuaj, tshuaj pleev, tshuaj pleev. Nws pab txhawm rau txhim kho kev ntxhib los mos, viscosity, thiab ruaj khov ntawm cov qauv no.
Kws tsim khoom: hauv cov tshuaj yeeb yaj kiab, hauv cov tshuaj hec yog siv los ua cov ntaub ntawv tuab thiab ncua cov neeg sawv cev xws li syrups zoo li syrups, raug tshem tawm, thiab gels.
Kev lag luam khoom noj khoom haus: HEC tau siv nyob rau hauv kev lag luam khoom noj ua ib qho tuab thiab ruaj khov hauv ntau theem, hnav khaub ncaws, thiab cov khoom qab zib.
Kev ua xua rau hydroxyethylcellulose
Kev ua xua rau HEC yog qhov tsawg kawg nkaus xwb tab sis tuaj yeem tshwm sim hauv cov neeg tau txais txiaj ntsig. Cov kev tawm tsam no tuaj yeem nthuav tawm ntau txoj kev, suav nrog:
Daim tawv nqaij khaus: Cov tsos mob muaj xws li cov xim liab, khaus, o, lossis pob ntawm qhov chaw tiv tauj. Cov tib neeg muaj cov tawv rhiab yuav tau pom cov tsos mob no thaum siv cov tshuaj pleev ib ce lossis cov khoom tu tus kheej muaj HEC.
Cov tsos mob ua pa: nqus tau hec hais, tshwj xeeb tshaj yog cov tsos mob ntawm chaw tsim khoom, tej zaum hawb pob, hawb pob, lossis ua pa tsis taus.
Kev ntxhov siab ntawm lub plab zom mov: kev noj haus ntawm HEC, tshwj xeeb hauv cov tib neeg muaj cov mob hnyuv, yuav ua rau cov tsos mob zoo li xeev, ntuav, lossis raws plab.
Anaphylaxis: nyob rau hauv cov neeg mob hnyav, kev ua xua tuaj yeem ua rau muaj kev phom sij los ntawm kev ua pa tawm ntawm cov ntshav, ua pa nyuaj, thiab tsis nco qab.
Kev kuaj mob ntawm hydroxyethylcellulose kev ua xua
Kev kuaj xyuas ib qho kev tsis haum tshuaj rau HEC feem ntau cuam tshuam nrog keeb kwm kev kho mob, kuaj lub cev, thiab kev ntsuas kev ua xua. Cov kauj ruam hauv qab no yuav ua tau:
Keeb kwm kev kho mob: Tus kws kho mob yuav nug txog cov tsos mob, tej zaum yuav raug rau HEC-muaj cov khoom lag luam, thiab ib qho keeb kwm ntawm kev ua xua lossis kev ua xua.
Kev kuaj lub cev: Kev kuaj lub cev yuav qhia tawm ntawm daim tawv nqaij voos lossis lwm yam kev ua xua.
Thaj kev sim: Thaj kev xeem cuam tshuam nrog kev thov cov tshuaj ib qho me me, suav nrog HEC, rau ntawm daim tawv nqaij kom pom txog tej yam mob. Qhov kev sim no pab txheeb xyuas cov lus sib tiv tauj dermatitis.
Cov tawv nqaij Prick Kuaj: Hauv daim tawv nqaij kuaj, ib qho me me ntawm kev ua xua tawm yog pricked rau hauv daim tawv nqaij, feem ntau nyob rau ntawm forearm lossis sab nraub qaum. Yog tias tus neeg ua xua rau hec, lawv tuaj yeem tsim cov tshuaj tiv thaiv ib cheeb tsam ntawm lub xaib ntawm lub prick tsis pub dhau 15-20 feeb.
Kev kuaj ntshav: kev kuaj ntshav, xws li cheigodigulin e) kev sim tshuaj, tuaj yeem ntsuas cov hlab ntshav, qhia tias muaj kev tsis haum.
Cov tswv yim tswj kev tswj hwm rau hydroxyethylcelleculose phiv
Tswj ib qho kev txwv rau HEC muaj feem cuam tshuam tsis txhob raug cov khoom lag luam uas muaj cov tshuaj no thiab kev siv tsim nyog kho tsis haum. Ntawm no yog qee cov tswv yim:
Kev Zam Txim: Txheeb xyuas thiab zam cov khoom uas muaj HEC. Qhov no yuav suav nrog ua tib zoo nyeem cov khoom lag luam thiab xaiv cov khoom xaiv uas tsis muaj HEC lossis lwm cov khoom xyaw cuam tshuam.
Hloov chaw: Tshawb nrhiav lwm yam khoom uas pabcuam cov hom phiaj zoo sib xws tab sis tsis muaj HEC. Ntau tus tuam ntxhab muaj kev ua yeeb yam zoo ntawm cov tshuaj pleev ib ce, cov khoom tu tus kheej, thiab kws tshuaj.
Cov tshuaj kho mob: Cov tshuaj sib xyaw ua ke xws li antihistamines (piv txwv li cov tsos mob ntawm kev ua xua, xws li khaus thiab pob khaus. Cov ntsiab lus corticosteroidsoids kuj yuav raug muab rau cov tawv nqaij uas txo cov tawv nqaij thiab khaus.
Kev npaj npaj thaum muaj xwm ceev: Cov tib neeg muaj keeb kwm kev ua xua heev, xws li yuav tsum tau siv nws thaum muaj xwm txheej ceev.
Kev sab laj nrog cov kws kho mob: Tham txog kev tswj hwm hec ua xua rau cov neeg saib xyuas kev noj qab haus huv, uas tuaj yeem muab cov lus qhia ntawm tus kheej.
Thaum hydroxyethylcellulose yog cov khoom siv dav hauv ntau yam khoom, kev ua xua rau cov compound no yog ua tau, albeit tsawg. Paub txog cov cim thiab cov tsos mob ntawm kev tshuaj xyuas kev kho mob thiab kuaj mob kom tsim nyog, thiab kev xav tias muaj kev fab tshuaj no. Los ntawm kev nkag siab txog cov kev pheej hmoo txaus ntshai nrog HEC kis tau thiab kev ntsuas kev ua tiav, zam kev tswj hwm lawv cov kev tsis haum tshuaj thiab txo qhov kev pheej hmoo ntawm kev tsis haum tshuaj.
