Khometic Qib Hec
Hydroxyethyl cellulose, raug xa mus ua HEC, cov tsos ntawm dawb lossis hmoov tawv fibroous cov khoom lossis cov hmoov txhuas, belongs rau cov tsis muaj ionic cellulose ether. Hydroxyethyl cellulose yog yooj yim soluble hauv dej, ob qho tib si txias thiab dej kub ua tau, muaj cua sov, lub cua sov, insoluble hauv cov teeb meem organic. Hydroxyethyl cellulose yog ib qho tseem ceeb dej-soluble cellulose thib ob thib ob tsuas yog carboxymethyl cellulose thiab hydroxypropy cellulose hauv lub ntiaj teb kev ua lag luam.
Txoj kev ua kom zoo nkauj teem nqiHec hydroxyethyl cellulose hydroxyethyl cellulose yog ib tug zoo forming forming tus neeg sawv cev, cov plaub hau, nruab nrab, tshuaj pleev ib ce. Hauv cov hmoov nplej qhuav yog ib hom av re - daws tus neeg sawv cev; Cov xab npum uas muaj hydroxyethyl cellulose muaj qhov pom tseeb ntawm kev txhim kho lub ntsej muag thiab kev lom zem ntawm cov ntaub.
Txoj kev ua kom zoo nkauj teem nqiHEC Hydroxyethyl Cellulose Kev Npaj Txoj Kev Npaj yog kom muab cov khoom siv alkali, tom qab sodium hydroxide cov tshuaj tiv thaiv, hauv qab cov tshuab nqus dej hauv nitrogen hauv nitrogen hauv nitrogen hauv nitrogen, thiab koom nrog Epoxy ethane Cov tshuaj tiv thaiv nyoos yog, nyeg ntxiv ethanol, acetic acid, thaum kawg, cov khoom tiav tau npaj los ntawm kev ntxuav, lub cev qhuav thiab qhuav.
Txoj kev ua kom zoo nkauj teem nqiHEC Hydroxyethyl cellulose nrog lub thickening, kev sib koom tes, kev tawm tsam, pleev xim, pleev xim, pleev xim thiab kua qaub, stabilizer, stabilizer, Resin, ntau lawm ntau lawm dispersant, textile sizing tus neeg sawv cev, cov dej khov, cov txheej txheem tso cai rau cov tshuaj lom neeg, cov khoom siv ua kom zoo rau cov tshuaj, zaj duab xis, cov txheej txheem duab dhos ua si rau cov ntsiav tshuaj txhua hnub, cov khoom siv ua yeeb yam rau cov ntsiav tshuaj, cov txheej txheem duab dhos ua si, cov duab ua si Cov ntaub ntawv, nplaum nplaum thiab stabilizer rau kev lag luam hluav taws xob, thiab lwm yam.
Hauv Suav teb kev ua lag luam, daim ntawv thov ntawm hydroxyethyl cellulose yog feem ntau muaj kuab lom, roj av thiab lwm thaj chaw, thiab tsawg dua hauv lwm daim teb. Tsis tas li ntawd, kev tsim cov hydroxyethyl cellulose hauv Suav teb yog feem ntau cov khoom siv tsawg kawg nkaus thiab cov khoom lag luam txhua hnub. Hauv kev ua lag luam siab kawg, tus naj npawb ntawm cov lag luam uas muaj feem cuam tshuam hauv Suav teb yog me, cov zis tsis txaus, thiab kev vam khom sab nraud yog loj. Tsav los ntawm kev hloov pauv ib sab thiab kev tiv thaiv kev tiv thaiv ib puag ncig thiab kev txhim kho cov kev lag luam hydrocessly yuav txhim kho kom zoo rau yav tom ntej.

Tus paHydroxyethyl cellulose yog ib qho tseem ceeb heev ntawm tes ether cov khoom siv nyob hauv ntiaj teb ntau lawm thiab muag khoom. Nws yog cov dej-soluble tsis-ionic cellulose, uas tuaj yeem siv dav hauv roj av, tshuaj, tshuab luam ntawv txhua hnub, thiab lwm yam kev lag luam, nrog rau kev lag luam dav dav. Tsav los ntawm kev thov, cov zis ntawm hydroxyethyl cellulose hauv Suav yog nce. Nrog kev txhim kho kev txhim kho ntawm kev noj haus thiab ua kom nruj ntawm cov cai tiv thaiv ib puag ncig, kev lag luam tab tom txhim kho ntawm qib siab. Cov kev lag luam uas tsis tuaj yeem ua raws li kev sib tw ntawm kev txhim kho hauv yav tom ntej yuav maj mam tshem tawm.
Hydroxyethyl cellulose hauv cov tshuaj pleev ib ce, cov khoom siv rau cov poj niam cev xeeb tub, cov duab muaj kev nyab xeeb, rau cov poj niam cev xeeb tub, cov duab muaj kev nyab xeeb yog 1, muaj peev xwm so kom muaj kev phom sij, rau cov poj niam cev xeeb tub, rau cov poj niam cev xeeb tub, tuaj yeem so, tsis muaj pob txuv ua rau.
Hydroxyethyl cellulose yog hluavtaws polymer nplaum siv nyob rau hauv cov tshuaj pleev ib ce ua cov tawv nqaij txias, ua yeeb yaj kiab sib zog ua yeeb yaj kiab thiab antioxidant.
Cov teeb meem yuav tsum tau sau tseg thaum sivtxoj kev ua kom zoo nkaujteem nqi Tus pahydroxyethyl cellulose:
1. Ua ntej thiab tom qab ib qho kev sib ntxiv ntawm cov tshuaj pleev ib ce qib hec hydrotyl cellulose, nplawm yuav tsum txuas ntxiv kom txog thaum kev daws teeb meem tau meej thiab meej.
2. Sab Cib TusKhometic Qib Hechydroxyethyl cellulose rau hauv lub tank ua haujlwm maj mam. Tsis txhob ntxiv nws hauv cov khoom loj lossis ncaj qha rau hauv lub tank sib xyaw.
3. Lub solubility ntawmtxoj kev ua kom zoo nkaujteem nqiTus paHydroxyethyl cellulose yog pom tseeb hais txog dej kub thiab pH tus nqi, yog li tshwj xeeb saib yuav tsum tau them rau nws.
4. Tsis txhob ntxiv ib qho kev ua yeeb yam alkaline rau qhov sib xyaw ua ntej cov hmoov hydrothethyl cellulose hmoov tau txias los ntawm dej. Ua kom muaj tus nqi PH tom qab ua kom sov pab kom yaj.
5. Rau qhov ua tau, ntxiv me mildew inhibitor ntxov.
6. Thaum siv siab viscosity kom zoo nkauj qib hec hydroxyethyl cellulose, lub concentration ntawm niam cawv yuav tsum tsis txhob siab dua li tus niam cawv yog qhov nyuaj ua haujlwm. Tom qab kho hydroxyethyl cellulose feem ntau tsis yooj yim rau tsim cov koog los yog spheres, tsis yuav nws ua insoluble kheej kheej kheej tom qab ntxiv dej.
