Methyl Hydrothethyl cellulose (MHEC) yog cellulose cellulose ether compound nrog ob lub methylation thiab hydroxyethetty. Hauv cov txheej txheej hauv dej, MHEC ua lub luag haujlwm tseem ceeb nrog nws lub cev thiab tshuaj siv tshuaj lom neeg.
I. Kev ua txuj ci zoo
Sam xim
Lub hydroxyethyl thiab methyl pawg nyob rau hauv mhec molecular qauv tuaj yeem tsim cov qauv network tau nyob hauv cov kev daws teeb meem aqueous, yog li zoo nce lub viscosity ntawm txheej. Qhov no tuab ua rau nws ua tiav cov rheology zoo tshaj plaws ntawm cov khoom siv qis, yog li txo tus nqi ntawm cov nqi thiab txuag nqi.
Rheological hloov kho
MHEC tuaj yeem muab cov txheej txheej zoo nkauj thiab cov khoom lag luam tawm los tiv thaiv. Nws cov yam ntxwv pseudoplastic ua rau cov txheej muaj cov qauv viscosity nyob rau hauv lub xeev thov, thiab thaum kawg tuaj yeem kho cov viscososity sai tom qab kev tsim kho yog ua tiav, txo cov sag lossis dripping.
Dej ceev
MHEC muaj cov dej ua kom zoo thiab muaj peev xwm tswj tau cov dej tso tawm. Cov cuab yeej no yog qhov tshwj xeeb tshaj yog rau kev tiv thaiv cov xim thaws dej los ntawm kev tawg, hmoov thiab tseem tuaj yeem txhim kho lub smoothness thiab kev sib txawv ntawm cov txheej txheem thaum lub sijhawm kev tsim kho.
Emulsion stability
Raws li surfactant, MHEC tuaj yeem txo cov xim av hauv cov xim thiab txhawb nqa cov xim sib txawv thiab txhawb nqa cov xim thiab tsis txhob flocculation thiab nag lossis daus ntawm cov xim xim.
Biodegradity
MHEC tau muab tau los ntawm cov duab ntuj ntuj thiab muaj cov xim zoo nkauj, uas ua rau nws pom tseeb cov xim tsev thiab pab ua kom muaj kuab paug rau ib puag ncig.
2. Cov haujlwm tseem ceeb
Tuab dua
MHEC muaj cov tuab rau cov xim pleev xim rau cov dej pleev xim txhawm rau txhim kho nws cov kev tsim kho thiab zaj duab xis los ntawm cov xim pleev xim rau ntawm cov xim. Piv txwv li, ntxiv MHEC rau looj xim muaj peev xwm ua cov txheej txheej ntawm phab ntsa kom tiv thaiv cov xim ntawm sagging thiab sag.
Rheology Regulator
MHEC tuaj yeem hloov kho cov rheology ntawm cov xim pleev xim rau kom ntseeg tau tias nws yooj yim los thov thaum lub xeev ruaj khov. Los ntawm kev tswj hwm rawv, MHEC zoo tsim kho cov kev tsim kho ntawm cov txheej txheej, ua kom haum rau ntau txheej txheem txheej txheej.
Dej-tuav tus neeg sawv cev
Hauv cov txheej txheej dej-ua cov khoom siv ntawm cov khoom ntawm MHEC pab kom ntev txheej ntawm cov dej, thiab tiv thaiv cov khoom kom qhuav thiab tiv thaiv kev tawg.
Lub stababilizer
Vim nws cov khoom muaj peev xwm zoo, MHEC tuaj yeem pab cov txheej txheem dej ua kom ruaj khov, zam kev ua kom muaj zog thiab flocculation ntawm cov khoom lag luam ruaj khov ntawm txheej.
Zaj duab xis-ua kev pab
Thaum lub sij hawm zaj duab xis tsim kev txheej txheem ntawm txheej, muaj MHEC tuaj yeem txhawb kev sib txuam thiab du ntawm txheej, kom cov txheej kawg muaj cov tsos zoo thiab ua tau zoo.
3. Daim ntawv thov ua piv txwv
Looj xim
Hauv looj cov xim looj, lub ntsiab muaj nuj nqi ntawm MHEC yog tuab thiab dej khaws cia. Nws tuaj yeem txhim kho txoj kev txhuam hniav thiab dov ntawm cov xim looj tshum, thiab paub meej tias cov txheej txheej zoo thiab cov khaub ncaws zoo thaum lub sijhawm ua kom qhuav. Tsis tas li ntawd, MHEC tuaj yeem txhim kho cov kev tawm tsam thiab cov khoom siv ntawm cov xim yas, ua kom cov txheej txheem kev tsim kho.
Dej Xim Woodbe
Hauv cov xim ntoo ntoo ntoo, MHEC txhim kho txoj kev pleev xim smoothness thiab kev sib txawv ntawm cov yeeb yaj kiab pleev xim los ntawm kev kho cov viscosity thiab rhelology ntawm cov xim. Nws kuj tseem tuaj yeem tiv thaiv cov xim los ntawm kev tsim sagging thiab fouling ntawm ntoo saum npoo av, thiab txhim kho cov nyhuv zoo nkauj thiab cov kav dej ruaj khov ntawm zaj duab xis.
Dej Ua Ntej Cov Xim Xim
Daim ntawv thov ntawm MHEC hauv cov xim kos duab cov duab kos tau txhim kho cov xim tsim kev tsim kho thiab lub qab ntom nti, nws tuaj yeem tiv thaiv cov hws thiab tsis quav ntsej. Ib qho ntxiv, lub cuab yeej siv dej hauv MHEC tuaj yeem txuas lub sijhawm kom qhuav ntawm cov xim pleev xim, txo cov kab nrib pleb thiab khoom nthab.
Cov Xim Dej
Hauv cov xim dej ntawm cov dej tsis huv, MHEC tsis tsuas yog ua rau cov xim tuab thiab ruaj khov ntawm cov xim, yog li cov xim muaj peev xwm tswj tau zoo thiab ua kom muaj kev lag luam nyob hauv ib puag ncig.
IV. Kev Lag Luam Kev Ua Lag Luam
Nrog rau kev tiv thaiv ib puag ncig ib puag ncig thiab kev siv ntau ntxiv rau cov ntaub ntawv dej ntsuab, kev lag luam xav tau cov xim dej uas tau cog qoob loo ntxiv. Raws li ib qho tseem ceeb uas tseem ceeb ntawm cov xim dej hauv dej, MHEC muaj kev lag luam dav.
Kev Txhawb Nqa Ib puag ncig Txoj Cai Kev Txhawb
Kev cai lij choj thoob ntiaj teb, ib puag ncig cov cai tau nce zuj zus los ntawm volations organic compound (voc) emissions, uas tau tshaj tawm daim ntawv thov ntawm cov dej ntws tawm. Raws li ib puag ncig tus phooj ywg additive, MHEC ua lub luag haujlwm tseem ceeb hauv cov dej dej, thiab nws cov kev thov yuav nce ntxiv nrog kev nthuav dav ntawm cov dej ntws ntawm cov dej ua lag luam.
Loj hlob thov hauv kev tsim kho kev tsim kho
Qhov kev thov nce qis hauv qis-VOC, kev ua tau zoo txheej hauv kev tsim kho ntawm MHEC hauv cov khaub ncaws hnav ntawm cov ntoo khaub ncaws hnav. Tshwj xeeb tshaj yog rau sab hauv thiab sab nrauv phab txheej ntawm phab ntsa, MHEC tuaj yeem muab kev tsim kho kev tsim kho zoo thiab ruaj khov kom tau raws li kev ua lag luam.
Nthuav daim ntawv thov cov txheej txheem txheej txheem
Qhov kev xav tau ntawm ib puag ncig tus phooj ywg muaj nyob rau hauv cov teb muaj kuj tau txhawb nqa daim ntawv thov ntawm cov dej uas muaj cov tshuaj tiv thaiv dej. Raws li muaj cov txheej txheem txheej txheem tsim kev ua phooj ywg zoo thiab cov kev ua tau zoo, MHEC yuav ua lub luag haujlwm ntau dua hauv kev txhim kho cov txheej txheem ua haujlwm thiab cov yam ntxwv ib puag ncig.
Methyl Hydrotyl Cellulose (MHEC) Ua lub luag haujlwm tseem ceeb nrog nws cov kev siv lub ntsej muag zoo, rov qab kho kom haum, dej rov qab, emulsion stability thiab biodegradability thiab biodegradability thiab biodegradabe. Nws daim ntawv thov hauv cov txheej txheej hauv dej tsis tsuas yog txhim kho kev tsim kho thiab ua kom zoo rau cov qauv ntawm kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov. Nrog rau kev ua lag luam cog qoob loo rau kev ua tau zoo, cov khoom lag luam qis, siv cov kev cia siab ntawm MHEC hauv daim teb no yuav yog qhov dav dav.
