Methylhydroxyrcelleculose (MHEC) yog cov khoom siv cellule thiab dav cellulose ete kom ua tau zoo ntawm cov nplaum thiab cov kab xev. Nws cov khoom tshwj xeeb thiab cov khoom siv lub cev ua rau kev txhim kho ntawm cov khoom lag luam no hauv ntau qhov tseem ceeb ntawm thaj chaw tseem ceeb.
Kev Hloov Hom
Ib qho ntawm cov haujlwm tseem ceeb ntawm MHEC hauv cov nplaum thiab cov sealants yog viscosity kev hloov kho. MHEC yog cov neeg sawv cev tuab uas tuaj yeem hloov kho cov viscosity ntawm cov qauv rau qib xav tau. Txoj kev hloov kho no yog qhov tseem ceeb heev rau kev ua tiav cov yam ntxwv raws li kev sib xws thiab ntws tawm rau daim ntawv thov.
Rheological cov khoom: MHEC coj ua piv txwv pseudoplastic lossis thixotropy rau cov nplaum thiab kev sib txuas lus. Pseudoproastic ua kom ntseeg tau tias cov khoom yuav tsum tsis tshua muaj viscous nyob rau hauv shear kev ntxhov siab (xws li thaum lub sijhawm thov) tab sis rov qab mus rau nws cov viscosity thawj thaum cov kev ntxhov siab raug tshem tawm. Cov cuab yeej no ua kom yooj yim daim ntawv thov kom yooj yim thiab txhim kho kev sib tw ntawm cov nplaum lossis cov khoom lag luam.
Sag tiv thaiv: los ntawm kev txhim kho lub viscosity, MHEC pab nyob rau hauv kev tiv thaiv kev tiv thaiv sagging lossis slumting ntawm cov nplaum thiab cov xov xwm tom qab daim ntawv thov, tshwj xeeb tshaj plaws tom qab cov chaw ntsug. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim kho thiab sib dhos ua ke uas ua kom tiav qhov chaw nyob yog qhov tseem ceeb.
Dej ceev
MHEC Cov Khoom Noj Kom Zoo Tshaj Plaws Cov Khoom Siv Hluav Taws Xob Zoo Tshaj, uas yog qhov tseem ceeb rau kev ua yeeb yam ntawm cov nplaum thiab cov khoom ntim, tshwj xeeb yog siv hauv kev ua yeeb yam lossis gypsum raws li cov qauv.
Kev tswj hwm hydration: hauv cov khoom xyaw thiab cov kab lis kev cai, MHEC pab ua kom muaj kev tswj hwm cov txheej txheem kev kho kom txaus. Qhov no tswj kav dej kom ntseeg tau tias cov khoom noj qabentitious txheej txheem tuaj yeem hnov mob thiab txhim kho lawv lub zog thiab kav ntev. Yog tsis muaj dej cia kom txaus, cov nplaum kom qhuav sai sai, ua rau muaj kev ua tsis tiav thiab txo qis.
Lub sij hawm ua haujlwm: Cov dej khaws cia muaj peev xwm MHEC kuj txuas lub sijhawm qhib thiab lub sijhawm ua haujlwm ntawm cov nplaum lossis cov khoom siv tswm ciab. Qhov no muab sijhawm ntau rau cov neeg siv sijhawm los kho thiab cov ntaub ntawv raug, uas yog muaj txiaj ntsig tshwj xeeb, wallpering, thiab lwm yam kev siv meej.
ADHESION ESTAB
MHEC muab cov khoom nplaum ntawm cov qauv tsim, txhim kho cov kev sib txuas tag nrho ntawm lub zog thiab lub zog ruaj khov.
Zaj duab xis tsim: MHEC ua ib zaj yeeb yaj kiab hloov tau thiab muaj zog thaum ziab, uas ua rau kom muaj zog ntawm cov nplaum. Zaj yeeb yaj kiab no ua tus choj nruab nrab ntawm lub substrate thiab cov nplaum txheej, txhim kho daim ntawv cog lus.
Kev Sib Tham Txog Nto: Muaj cov MHEC tuaj yeem hloov kho cov yam ntxwv saum npoo ntawm cov nplaum lossis cov khoom ntim, nce nws lub peev xwm los ntub thiab nkag mus rau palous substrates. Qhov no txhim kho cov ntawv pib thiab lub sij hawm ntev, kom ntseeg tau ntau txoj kev txhim khu kev qha.
Kev ua haujlwm
Kev suav nrog MHEC hauv cov nplaum thiab cov xov xwm txhim kho lawv cov haujlwm, ua rau lawv siv tau yooj yim rau lis thiab thov.
Du daim ntawv thov: MHEC muaj txiaj ntsig rau txoj kev du thiab homogeneous kev ntxhib los mos, txo cov lumps thiab inconsistencies nyob rau hauv cov nplaum lossis sealant. Qhov no ua kom pom tseeb ib daim ntawv thov, uas yog qhov tseem ceeb rau kev ua tiav cov khaub ncaws hnav ris tsho thiab kev ua kom zoo nkauj.
Txo huab cua nkag: cov lus rheological muab pov tseg los ntawm MHEC pab nyob rau hauv kev ua kom huab cua ua ke thaum sib tov thiab kev thov. Qhov no ua rau muaj cov npuas huab cua tsawg dua hauv cov nplaum tsim los yog sib foob, txhim kho nws cov khoom thiab cov tsos.
Ruaj khov
MHEC muaj kev ruaj khov rau kev ruaj ntseg ntawm cov nplaum thiab cov xov xwm, ob lub sijhawm cia thiab tom qab daim ntawv thov.
Txee Lub Neej: MHEC pab nyob rau hauv kev tsim qauv los ntawm kev tiv thaiv theem sib cais thiab kev ua kom pom tseeb ntawm cov khoom noj. Qhov no txuas lub txee lub neej ntawm cov khoom lag luam thiab ua kom ua tiav kev ua tau zoo nyob rau lub sijhawm.
Qhov kub thiab txias thiab pH stability: mHEC coj zoo muaj kev ruaj khov hla ntau yam kub thiab qib. Qhov no ua rau cov nplaum thiab cov lag luam zoo dua ntau cov kev ua tau zoo hauv cov huab cua sib txawv hauv ob qho chaw ua haujlwm kub thiab huab cua sov, nrog rau cov acidic lossis alkaline ib puag ncig.
Cov ntawv thov hauv cov nplaum tshwj xeeb thiab cov xov xwm
Cov nplaum nplaum: hauv cov nplais nplaum, MHEC muab cov dej ua kom zoo, ua kom muaj kev haus dej kom zoo ntawm cov vuas thiab cov nplaum kom huv. Nws kuj txhim kho qhov haujlwm thiab qhib lub sijhawm, pub rau kev tso siab ncaj ncees thiab kev hloov kho cov vuas.
Wallpapers thiab cov phab ntsa phab ntsa: MHEC txhim kho lub viscesives thiab cov khoom siv du thiab muaj zog nplaum rau ntau qhov chaw phab ntsa. Nws lub peev xwm los txo cov cua rau kev ua kom muaj npuas-ua tiav dawb.
Gypsum-based sib chaws sib koom ua ke sib txuas: hauv gypsum-based ferbants thiab cov tebchaw sib koom ua ke, MHEC muab cov dej sib koom ua ke thiab ua haujlwm, ua haujlwm zoo dua. Nws kuj tseem pab tau txo qis shrinkage thiab tawg thaum lub sijhawm ua kom qhuav.
Siv cov kev siv no: MHEC tau siv hauv kev tsim cov duab ntxiab los txhim kho lawv viscosity, adhesion, thiab huab cua tsis kam. Nws ua kom pom tseeb tias cov xov xwm tseem yoog tau thiab ruaj khov rau lub sijhawm, muab kev tiv thaiv ntev ntev rau ib puag ncig.
Methylhydroxyrcelleculose (MHEC) yog kev ua haujlwm ntau ntxiv uas ua tau zoo dua li cov ua yeeb yam ntawm cov nplaum thiab cov kab xev. Los ntawm kev txhim kho viscosity, cov dej khaws cia, kev ua haujlwm zoo, thiab ruaj khov, mHEC kom paub tias cov khoom uas tsis tshua xav tau ntawm ntau yam kev siv. Txawm hais tias nyob rau hauv kev tsim kho, tilder, wallpooming, lossis lwm yam kev lag luam, kev suav nrog ntawm mHEC hauv cov nplaum thiab kev ua tau zoo ua rau kev ua haujlwm zoo dua, thiab yooj yim ntawm kev siv. Nws cov versatility thiab cov txiaj ntsig ua rau nws tsis tseem ceeb ntawm cov nplaum thiab cov khoom siv hluav taws xob niaj hnub.
