Methylhydroxyethylcellulose (MHEC) yog ib qho tseem ceeb ntawm cov cellulose ether uas tau siv dav hauv kev tsim kho kev lag luam vim nws cov khoom zoo heev. Lub hauv paus qauv ntawm MHEC yog kev taw qhia txog methyl thiab hydroxyethyl pawg mus rau hauv cov pob txha cellulose, uas yog chemically hloov kom muaj cov yam ntxwv tshwj xeeb, xws li thickening, dej tuav, adhesion thiab zaj duab xis tsim.
thickening nyhuv
MHEC muaj cov nyhuv thickening zoo thiab tuaj yeem ua kom cov viscosity ntawm mortars thiab coatings. Hauv kev tsim kho, viscosity ntawm mortar ncaj qha cuam tshuam rau nws txoj kev tsim kho thiab cov nyhuv kawg. Los ntawm kev ua kom cov viscosity ntawm cov mortar, MHEC ua rau nws tsis tshua muaj sag thaum thov thiab tuaj yeem sib npaug ntawm phab ntsa, txhim kho kev tsim kho thiab ua haujlwm zoo. Tsis tas li ntawd, ntxiv MHEC rau txheej txheej tuaj yeem tiv thaiv cov txheej txheem los ntawm sagging thiab splashing, kom ntseeg tau qhov sib xws thiab smoothness ntawm txheej.
tuav dej
Kev tuav dej yog ib qho tseem ceeb tshaj plaws ntawm MHEC hauv cov khoom siv hauv tsev. Thaum lub sij hawm tsim kho, cov dej noo nyob rau hauv mortar thiab qhob yog txo kom sai vim evaporation thiab nqus, ua rau cov khoom siv zog poob thiab tawg. MHEC tuaj yeem khaws dej tau zoo, txuas ntxiv lub sijhawm ntub dej ntawm mortar thiab pob zeb, txhawb kom muaj dej txaus ntawm cov cement, thiab txhim kho lub zog thiab ruaj khov ntawm cov khoom. Tshwj xeeb tshaj yog nyob rau hauv high-temperature los yog qhuav tsim ib puag ncig, dej tuav dej num ntawm MHEC yog ib qho tseem ceeb tshwj xeeb.
kev sib raug zoo
MHEC kuj muaj cov khoom sib txuas zoo heev thiab tuaj yeem txhim kho lub zog sib txuas ntawm cov mortar thiab substrate. Nyob rau hauv cov pobzeb nplaum thiab sab nrauv phab ntsa rwb thaiv tsev, MHEC raws li ib qho ntxiv tuaj yeem txhim kho lub zog ntawm cov nplaum thiab tiv thaiv cov vuas los ntawm kev poob thiab cov txheej txheem rwb thaiv tsev los ntawm kev tawg. Los ntawm kev siv MHEC hauv kev tsim qauv, kev ntseeg siab thiab kev ua haujlwm ntev ntawm cov khoom siv hauv tsev tuaj yeem ua kom ntseeg tau.
tsim zaj duab xis
MHEC muaj cov cuab yeej ua yeeb yaj kiab zoo thiab tuaj yeem tsim cov yeeb yaj kiab tiv thaiv zoo rau saum npoo. Cov yeeb yaj kiab tiv thaiv no tiv thaiv cov dej los ntawm evaporating sai heev thiab txo cov kab nrib pleb thiab shrinkage ntawm cov khoom siv. Hauv cov txheej txheem dej tsis zoo thiab cov ntaub ntawv sib khi, cov yeeb yaj kiab tsim los ntawm MHEC tuaj yeem txhim kho cov dej tsis zoo ntawm cov khoom siv thiab ua kom cov dej tsis zoo ntawm lub tsev. Hauv cov plag tsev tus kheej, MHEC tuaj yeem txhim kho qhov smoothness thiab flatness ntawm hauv pem teb nto thiab muab cov khoom zoo nkauj zoo nkauj.
Lwm cov haujlwm
Ntxiv nrog rau lub luag haujlwm tseem ceeb saum toj no, MHEC muaj qee qhov kev siv tseem ceeb hauv kev tsim kho. Piv txwv li, ntxiv MHEC rau tshuaj tsuag gypsum tuaj yeem txhim kho kev tsim kho kev ua tau zoo thiab qhov smoothness ntawm gypsum. Nyob rau sab nrauv phab ntsa putty, MHEC tuaj yeem txhim kho qhov yooj yim thiab adhesion ntawm putty thiab tiv thaiv kev tawg thiab poob tawm. Tsis tas li ntawd, MHEC kuj tseem tuaj yeem siv los ua tus stabilizer los tiv thaiv delamination thiab nag lossis daus ntawm cov ntaub ntawv hauv tsev thaum lub sijhawm khaws cia, ua kom ruaj khov thiab sib xws ntawm cov ntaub ntawv.
Daim ntawv thov
Pobzeb nplaum: Ntxiv MHEC rau cov pobzeb nplaum tuaj yeem ua rau lub sijhawm qhib thiab hloov lub sijhawm ntawm cov pobzeb nplaum, ua rau kev tsim kho kom yooj yim dua, thaum txhim kho lub zog sib txuas thiab tiv thaiv cov vuas los ntawm kev poob.
Sab nrauv phab ntsa rwb thaiv tsev: MHEC raws li ib tug additive yuav txhim khu lub adhesion thiab dej tuav ntawm rwb thaiv tsev mortar thiab txhim kho kev tsim kho kom zoo thiab durability ntawm rwb thaiv tsev txheej.
Self-leveling pem teb: Ntxiv MHEC rau nws tus kheej-leveling cov ntaub ntawv hauv pem teb tuaj yeem txhim kho qhov fluidity thiab flatness ntawm hauv pem teb thiab xyuas kom meej qhov smoothness thiab zoo nkauj ntawm hauv pem teb nto.
Waterproof txheej: Daim ntawv thov ntawm MHEC nyob rau hauv waterproof txheej yuav txhim kho cov zaj duab xis-tsim thiab waterproof kev ua tau zoo ntawm txheej thiab tiv thaiv kom txhob ya raws thiab cov khoom puas.
Methylhydroxyethylcellulose yog dav siv nyob rau hauv kev tsim kho tej yaam num vim nws versatility thiab zoo heev zog. Los ntawm thickening, dej tuav, sib txuas rau kev tsim cov yeeb yaj kiab, MHEC plays lub luag haujlwm tseem ceeb hauv kev txhim kho kev tsim kho thiab kev ua haujlwm kawg ntawm cov khoom siv hauv tsev. Nrog rau kev nce qib ntawm kev siv thev naus laus zis thiab kev sib sib zog nqus ntawm kev tshawb fawb daim ntawv thov, daim ntawv thov kev cia siab ntawm MHEC hauv kev tsim kho yuav nthuav dav.
