Xaiv cov tsim nyog hydroxyethyl methylulose (HEMC) Ntau yam yuav tsum to taub ntau yam yuav tsum tau txais kev nkag siab ntau yam yuav tsum muaj cov qauv zoo, thiab cov cai tshwj xeeb ntawm txoj haujlwm lossis daim ntawv thov.
1. Nkag Hemc:
1.1 Tshuaj lom neeg cov khoom:
HEMC yog qhov tsis-ionic cellulose ither tau los ntawm cellulose, lub ntuj polymer pom hauv cov nroj tsuag. Nws yog synthesized los ntawm kev kho cellulose nrog alkali thiab tom qab ntawd reacting nrog ethylene oxide thiab methyl chloride. HEMC yog soluble nyob rau hauv dej txias thiab ua kom muaj qhov tseeb, tsis muaj kuab.
1.2 Daim Ntawv Thov:
HEMC yog dav siv nyob rau hauv ntau yam kev lag luam suav nrog kev tsim kho, chaw muag tshuaj, tsho me, cov khoom lag luam cov khoom lag luam thiab cov khoom tu tus kheej. Nws lub luag haujlwm tseem ceeb suav nrog cov tuab tuab, dej khaws cia, zaj duab xis tsim thiab ruaj khov.
1.3 Cov Qauv Zoo:
Thaum xaiv ib qho hemc ntau yam, koj yuav tsum xyuas kom meej tias nws ua tau raws li nws ua tau raws li cov qauv kev ua tau zoo, xws li ISO 9001 lossis cov qauv kev lag luam. Cov qauv lav cov khoom lag luam purity, sib xws thiab kev ua tau zoo.
2. Qhov xwm txheej los xav txog:
2.1 Viscosity:
HEMC ntau yam muaj nyob rau qib sib txawv, los ntawm qhov tsawg rau siab. Qhov xav tau viscosity nyob ntawm daim ntawv thov thiab xav tau xwm yeem ntawm kev daws teeb meem lossis tsim. Piv txwv, qib viscosity viscosity yog qhov haum rau cov txheej txheem thickening los yog cov nplaum, thaum tus qib qis dua tuaj yeem haum rau cov kws tshuaj zoo.
2.2 Paus Loj:
Lub particle loj ntawm HEMC cuam tshuam nws cov kev tawg thiab kev ua tau zoo hauv ntau yam kev siv. Cov ntaub pua tsev ua kom tawg tau yooj yim dua hauv dej thiab tuaj yeem muab cov khoom siv hluav taws xob zoo dua hauv qee qhov qauv.
2.3 Kev Tuav Dej:
Ib qho ntawm cov haujlwm tseem ceeb ntawm HEMC yog dej khaws cia, uas yog qhov tseem ceeb rau kev thov xws li cugash-raws li stucco. HEMC lub peev xwm los khaws dej thiab tiv thaiv kev ziab ntxov ua rau muaj kev cuam tshuam cov txheej txheem thiab kev muaj zog ntawm cov ntaub ntawv.
2.4 Zaj duab xis tsim:
Hauv cov txheej txheej thiab cov khoom saib xyuas tus kheej, hemc feem ntau siv los ua ib zaj duab xis nyias, uniform ntawm ib qho chaw. Cov yeeb yaj kiab ua yeeb yam ntawm HEMC raug cuam tshuam los ntawm cov lus xws li molecular hnyav thiab qib hloov chaw. Xaiv cov raug ntau yam nrog cov khoom ua yeeb yaj kiab uas xav tau yog qhov tseem ceeb kom ua tiav qhov kev ua tau zoo.
2.5 Sib Ntaus:
HEMC yuav tsum sib xws nrog lwm cov khoom xyaw lossis ntxiv rau hauv cov qauv. Kev tsis muaj peev xwm tuaj yeem ua rau muaj teeb meem xws li theem sib cais, viscosity ploj, lossis kev ua phem. Yuav tsum tau ua kom muaj kev sib haum yuav tsum tau ua thaum muab cov khoom lag luam tshiab lossis kho cov qauv uas tam sim no.
2.6 ib puag ncig qhov tseeb:
Ib puag ncig qhov ntsuas ib puag ncig xws li ntsuas kub, av noo thiab UV kis yuav tsum tau txiav txim siab. Qee hom hemc tuaj yeem ruaj khov nyob rau qee qhov xwm txheej, ua rau lawv haum rau kev siv sab nraum zoov lossis cov ntawv sau ua ntej tau txais kev mob siab ib puag ncig.
3. Xaiv cov txheej txheem:
Yuav tsum muaj:
Pib los ntawm kev pom tseeb koj cov kev xav tau thiab cov kev qhia tshwj xeeb rau HEMC ntau yam. Xav txog yam tseem ceeb xws li viscosity, dej ceev, ua yeeb yaj kiab ua yeeb yaj kiab, thiab sib xyaw nrog lwm cov khoom xyaw.
3.2 Ua qhov kev xeem:
Thaum koj tau txheeb pom HEMC ntau hom uas ua tau raws li koj qhov yuav tsum tau ua, kev ua haujlwm kom ntsuas kom ntsuas lawv qhov kev ua tau zoo hauv koj daim ntawv thov tshwj xeeb. Qhov no tuaj yeem suav nrog kev sim ua haujlwm, sim kev sim lossis kev sim ua si, nyob ntawm seb qhov project.
3.3 Txiav txim tus nqi:
Piv tus nqi ntawm ntau hom hemc ntau yam thaum txiav txim siab lawv ua tau zoo thiab haum rau koj daim ntawv thov. Yuav kom ua tiav cov txiaj ntsig xav tau nyob rau hauv cov nyiaj txiag kev teeb meem, qhov sib npaug yuav tsum tau raug ntau ntawm cov nqi zoo thiab cov khoom lag luam zoo.
3.4 Pab Tswv Yim Pab Tswv Yim:
Tham rau Hempl tus neeg xa khoom lossis cov chaw tsim khoom los mus sau cov ntaub ntawv ntau ntxiv txog lawv cov khoom lag luam thiab cov kev pabcuam txhawb kev pab. Lawv tuaj yeem muab cov kev pom zoo thiab cov lus qhia raws li lawv cov kev txawj ntse thiab kev paub dhau los.
3.5 Txheeb xyuas cov ntaub ntawv kev nyab xeeb:
Nco ntsoov tias HEMC ntau yam koj xaiv tau ntsib kev nyab xeeb thiab kev tswj hwm yuav cuam tshuam rau koj kev lag luam. Txheeb xyuas cov ntawv qhia txog kev nyab xeeb thiab cov kev cai tswj cov cai lij choj los txheeb xyuas cov qauv kev cai thiab cov cai.
3.6 Tshuaj Ntsuam Xyuas Cov Sij Hawm Ntev:
Xav txog cov txiaj ntsig tau ntev ntawm kev xaiv HEMC ntau yam, xws li kev txhim kho cov khoom lag luam tsim, ua kom tau cov nqi txij nkawm. Kev nqis peev hauv cov dej siab zoo tuaj yeem ua rau muaj kev txuag nyiaj txiag thiab tau txais txiaj ntsig dhau lub neej ntawm cov khoom.
4. Hauv kev xaus:
Kev xaiv HEMC tsim nyog ntau yam yuav tsum ua tib zoo saib xyuas cov ntsiab lus xws li cov dej tuav, ua yeeb yaj kiab, sib xyaw, thiab tus nqi. Los ntawm kev nkag siab txog koj cov kev kawm tshwj xeeb thiab ua cov kev ntsuas kom haum, koj tuaj yeem xaiv HEMC ntau yam uas ua tau raws li koj cov kev xav tau thiab muab cov kev ua tau zoo tshaj plaws hauv koj daim ntawv thov. Ua haujlwm nrog cov chaw muab khoom thiab cov chaw tsim khoom tuaj yeem muab kev txhawb nqa muaj txiaj ntsig thiab muaj kev tshaj lij thoob plaws cov txheej txheem xaiv, ua kom koj txoj haujlwm lossis khoom lag luam.
