Hauv kev lag luam xim, MHEC feem ntau yog siv los ua cov thickener, stabilizer thiab suspending agent, nrog rau cov haujlwm hauv qab no:
Kev txhim kho rheology ntawm cov xim: MHEC tuaj yeem ua kom cov xim ruaj khov thaum lub sijhawm khaws cia, tiv thaiv nag lossis daus, thiab muaj cov dej ntws zoo thiab txhuam cov cim ploj thaum txhuam.
Zaj duab xis-tsim cov khoom: Hauv cov xim pleev xim dej, MHEC tuaj yeem txhim kho lub zog, dej tsis kam thiab txhuam tsis kam ntawm cov zaj duab xis txheej, thiab txuas ntxiv lub neej kev pab cuam ntawm txheej zaj duab xis.
Stabilizing pigment dispersion: MHEC tuaj yeem tswj cov xim tsis sib xws ntawm cov xim thiab cov khoom ntim, thiab tiv thaiv cov txheej txheem los ntawm stratification thiab nag lossis daus thaum khaws cia.
3. Kev lag luam tshuaj txhua hnub
Ntawm cov tshuaj niaj hnub, MHEC tau siv dav hauv tshuaj zawv plaub hau, da dej gel, xab npum tes, tshuaj txhuam hniav thiab lwm yam khoom. Nws lub luag haujlwm tseem ceeb yog:
Thickener: MHEC yog siv los ua cov thickener hauv cov khoom siv xab npum los muab cov khoom tsim nyog viscosity thiab kov, txhim kho kev siv.
Zaj duab xis qub: Hauv qee cov khoom txias thiab cov khoom siv styling, MHEC yog siv los ua cov yeeb yaj kiab qub los pab tsim cov yeeb yaj kiab tiv thaiv, tuav cov plaub hau thiab tiv thaiv plaub hau.
Stabilizer: Hauv cov khoom xws li tshuaj txhuam hniav, MHEC tuaj yeem tiv thaiv cov khoom ua kua stratification thiab tswj cov khoom sib xws thiab ruaj khov ntawm cov khoom.
4. Kev lag luam kws tshuaj
MHEC kuj tau siv dav hauv kev lag luam tshuaj, feem ntau suav nrog:
Binder thiab disintegrant rau cov ntsiav tshuaj: MHEC, raws li ib tug excipient rau cov ntsiav tshuaj, tuaj yeem txhim kho cov adhesion ntawm cov ntsiav tshuaj thiab ua rau lawv yooj yim rau kev tsim thaum lub sij hawm tsim khoom. Nyob rau tib lub sijhawm, MHEC tseem tuaj yeem tswj hwm qhov sib cais ntawm cov ntsiav tshuaj, yog li tswj kev tso tshuaj.
Matrix rau cov tshuaj pleev: Hauv cov tshuaj pleev ib ce xws li tshuaj pleev thiab tshuaj pleev, MHEC tuaj yeem muab cov viscosity tsim nyog, kom cov tshuaj tuaj yeem sib npaug rau ntawm daim tawv nqaij thiab txhim kho kev nqus ntawm cov tshuaj.
Tus neeg saib xyuas kev tso tawm: Hauv qee qhov kev npaj tso tawm, MHEC tuaj yeem ncua lub sijhawm ntawm kev siv tshuaj los ntawm kev tswj hwm tus nqi ntawm cov tshuaj.
5. Kev lag luam zaub mov
Hauv kev lag luam zaub mov, MHEC feem ntau yog siv los ua zaub mov ntxiv rau:
Thickener: Hauv cov khoom noj xws li ice cream, jelly, thiab cov khoom noj siv mis, MHEC tuaj yeem siv los ua cov thickener los txhim kho cov saj thiab cov qauv ntawm cov khoom noj.
Stabilizer thiab emulsifier: MHEC tuaj yeem ua kom ruaj khov emulsions, tiv thaiv stratification, thiab xyuas kom meej qhov sib xws thiab kev ntxhib los mos ntawm cov khoom noj.
Zaj duab xis qub: Hauv cov yeeb yaj kiab uas siv tau thiab cov txheej txheem, MHEC tuaj yeem tsim cov yeeb yaj kiab nyias rau kev tiv thaiv thiab khaws cia.
6. Textile printing thiab dyeing kev lag luam
Hauv kev lag luam textile thiab dyeing kev lag luam, MHEC, ua cov thickener thiab zaj duab xis qub, muaj cov haujlwm hauv qab no:
Printing thickener: Hauv cov txheej txheem luam ntawv textile, MHEC tuaj yeem tswj tau qhov dej ntawm cov xim zoo nkauj, ua rau cov qauv luam tawm meej thiab cov npoo zoo.
Textile ua: MHEC tuaj yeem txhim kho qhov kev xav thiab pom ntawm textiles, ua rau lawv softer thiab smoother, thiab kuj txhim kho wrinkle kuj ntawm fabrics.
7. Lwm yam kev siv
Ntxiv rau thaj chaw tseem ceeb saum toj no, MHEC kuj tseem siv rau hauv cov hauv qab no:
Oilfield exploitation: Hauv cov dej drilling, MHEC tuaj yeem siv los ua cov thickener thiab filtrate reducer los txhim kho cov rheology ntawm drilling kua thiab txo cov filtrate poob.
Daim ntawv txheej: Hauv daim ntawv txheej, MHEC tuaj yeem siv los ua cov thickener rau txheej cov kua dej los txhim kho smoothness thiab gloss ntawm daim ntawv.
Methyl hydroxyethyl cellulose yog dav siv nyob rau hauv ntau industries xws li tsev cov ntaub ntawv, coatings, niaj hnub tshuaj, tshuaj, khoom noj khoom haus, textile printing thiab dyeing vim nws zoo heev thickening, dej tuav, film-forming, bonding thiab lubricating zog. Nws ntau yam kev siv thiab ntau yam ua rau nws yog ib qho tseem ceeb thiab cov khoom tseem ceeb hauv kev lag luam niaj hnub.
