Khoom Taw qhia ntawm Hydroxyethy Cellule Cellulose Hemc

Hydroxyethyl Methyl Cellulose (HEMC)Sawv raws li pivotal compound hauv cov kev lag luam niaj hnub, kho cov txheej txheem thiab cov khoom nyob thoob plaws cov ntawv thov. Nrog nws cov yam ntxwv tshwj xeeb thiab muaj kev ua haujlwm sib txawv, hemc tau dhau los ua cov khoom siv tsis tseem ceeb hauv kev tsim kho, tshuaj, tshuaj pleev, tshuaj pleev ib ce, thiab ntau dua.

Muaj pes tsawg leeg thiab cov khoom:
HEMC, muab tau los ntawm cellulose, yog synthesized los ntawm cov tshuaj tiv thaiv ntawm alkali cellulose nrog methyl chloride thiab ethylene oxide. Qhov no ua rau muaj kev sib txuas nrog cov pab pawg methyl thiab cov pab pawg hydroxyethyl txuas rau lub anhydroglucose rau ntawm cellulose. Cov degree ntawm kev hloov pauv (DS) ntawm HEMC, txiav txim los ntawm cov pab pawg maum nees ntawm cov roj hmab hloov chaw, qhia nws cov khoom thiab kev siv.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm HEMC yog nws cov dej solubility, uas ua rau nws cov nqi hluav taws xob nyob rau hauv ntau li qub apebe. Nws ua kom zoo ua tuab tuab, ua yeeb yaj kiab ua yeeb yaj kiab, thiab kev xaiv cov khoom siv, kev xaiv uas xav tau kev lag luam rheatoral thiab ruaj khov. Ntxiv mus, hemc muaj pseudoplastic cwj pwm, rendering nws shear-thinning, yog li ua kom yooj yim thov thiab kis tau yooj yim.

Cov Ntawv Thov:

Kev Lag Luam Kev Tsim Kho Kev Tsim Kho:
HEMC ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm, feem ntau yog cov khoom siv hydrophilic polymer addititive hauv cov khoom siv Maas-raws li cov ntaub ntawv. Nws lub peev txheej so kom muaj peev xwm ua tau lub zog ua haujlwm ntev ntawm kev sib khib thiab pob zeb ua kom zoo li kev ziab khaub ncaws kom qhuav thiab tawg. Tsis tas li ntawd, Hemc txhim kho adhesion thiab cohesion, koom tes rau lub zog thiab kav cov khoom siv.

Kws Tshuaj Txia:
Hauv cov tshuaj tsim qauv, hemc ua haujlwm ua ib qho kev zam tshwj xeeb vim nws biocompatibility, tsis muaj txiaj ntsig, thiab ntxim nyiam xwm. Nws pom dav dav hauv kev tswj hwm cov tshuaj tiv thaiv kev siv tshuaj, qhov chaw nws ua raws li ib tug matrix yav tas los, txhawb nqa kev siv yeeb tshuaj ntau ntxiv. Ib qho ntxiv, hemc muaj nuj nqi raws li viscosity concifiier hauv cov duab kos duab, txhim kho cov khoom ruaj khov thiab sib txawv.

Tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej:
HEMC cov lus pom zoo nyob rau hauv kev tsim cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej tiv rau nws cov yeeb yaj kiab-ua yeeb yaj kiab thiab thickenies. Nws ua haujlwm ruaj khov rau hauv emulsions, tiv thaiv theem sib cais thiab muab cov tshuaj saws zoo rau cov cream thiab lotions. Ntxiv mus, hemc ua raws li kev ncua tus neeg sawv cev hauv cov tshuaj zawv plaub hau thiab lub cev ntxuav, kom faib cov khoom sib txuam ntawm cov khoom uas raug tshem tawm.

Xim thiab pleev xim:
Nyob rau hauv cov xim pleev xim rau kev lag luam thiab pleev xim rau kev lag luam ntau ntxiv, txhim kho viscosity, sag tiv, thiab xim sib xws. Nws cov clealening clealenate pab rau kev ncua ntawm cov pigments thiab fillers, tiv thaiv kev daws teeb lub sijhawm thiab ntawv thov. Tsis tas li ntawd, HEMC uas cuam tshuam tau zoo heev ntawm cov teeb meem rau cov txheej txheej, ua rau kom du thiab niaj hnub ua tiav.

Cov txiaj ntsig:

Lub Hemc muaj cov txiaj ntsig ntau thoob plaws hauv kev lag luam:
Kev ua haujlwm tau zoo: Hemc ua kom muaj zog ua haujlwm ntev ntawm cov khoom siv tsim kho, yooj yim ntawm kev thov thiab txhim kho tag nrho cov khoom lag luam.
Txhim kho cov khoom lag luam kev ua tau zoo: hauv cov tshuaj thiab cov tshuaj pleev ib ce, hemc txhim kho ua qauv ruaj khov, sib xws, thiab ua tau zoo, ua rau cov khoom lag luam zoo dua.
Tus nqi efficiency: los ntawm kev ua kom zoo rheological cov khoom thiab txo cov khoom siv cov khoom siv, HEMC pab cov txheej txheem kev tsim khoom, ua rau cov nqi txuag.
Kev Nyab Xeeb Ib puag ncig: Hemsc, tau muab tau los ntawm cov khoom siv tau yooj yim dua, ua kom cov hom phiaj ruaj khov, muab kev xaiv hauv eco-phooj ywg rau cov khoom sib ntxiv.
Versatility: Nrog nws cov ntawv thov dav dav thiab hloov kho cov khoom siv, hemc rau cov kev daws teeb meem ntau yam.

Hydroxyethy cellulose (HEMC) sawv ua pob zeb hauv kev lag luam niaj hnub, cov neeg raug tsim tawm, versatility, thiab kev ntseeg tau. Nws cov kev ua haujlwm tshwj xeeb tau muaj kev ua haujlwm ntau yam tau muaj cov kev hloov pauv thiab cov khoom lag luam hla kev tsim kho, chaw muag tshuaj, tshuaj pleev ib ce, thiab dhau mus. Raws li kev lag luam txuas ntxiv hloov zuj zus, HEMC seem mus rau tsav tsheb txuas ntxiv, siv hauv lub caij nyoog tshiab ntawm kev ua haujlwm tshiab, muaj kev ua tau zoo, thiab kev ua tau zoo.
