1. Taw qhia rau hydroxyethy Methylcelulose
Hydroxyethyl Methyl Cellulose (HEMC)yog cov dej tsis-ionic-soluble cellulose cellulose cellulose solulose ua los ntawm kev siv tshuaj lom neeg xws li alkalinization thiab etherification ntawm ntuj cellulose. Nws muaj cov dej ua kom zoo heev, cov dej tuav, zaj duab xis, cov khoom siv hauv tsev thiab yog siv cov khoom siv hauv tsev, cov tshuaj pleev, khoom noj thiab lwm thaj teb. Hauv kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv cov hmoov qhuav thiab putty hmoov, hemc ua lub luag haujlwm tseem ceeb.
2. Lub luag haujlwm ntawm kev txhim kho cov txheej txheem
Txhim kho kev tsim kho kev tsim kho
Ntawm cov ntaub ntawv hauv tsev, hemc muaj cov khoom siv thickening zoo heev thiab tuaj yeem txhim kho lub thixotropy thiab sag tsis kam ntawm cov ntaub ntawv. Cov yam ntxwv no ua rau kev tsim kho kom yooj yim dua. Tshwj xeeb tshaj yog thaum ua ntawv thov ntawm qhov chaw ntsug, cov khoom tsis yooj yim rau SAG, ua kom yooj yim rau cov haujlwm ua haujlwm thiab txhim kho kev tsim kho.
Rial tuaj yeem ua tau kom haum rau lub sijhawm ntev tom qab tau coated lossis do. Cov neeg ua haujlwm tsim kho no ntxiv rau kev hloov kho thiab kho kom zoo thiab txhim kho kev ua haujlwm zoo.
3. Lub luag haujlwm ntawm kev txhim kho kev ua tau zoo
Cov Khoom Siv Dej Zoo Tshaj Plaws
Ib qho ntawm HEMC feem ntau cov khoom lag luam tshaj plaws yog nws txoj kev ua kom tau dej zoo. Hauv kev ua kom haum lossis gypsum-raws li cov neeg nplua nuj, hemc tuaj yeem txo qis cov dej ntws thiab ua kom cov cement lossis gypsum tau muaj dej noo txaus thaum cov dej cawv. Qhov no tsis tsuas yog txhim kho lub zog thiab kev sib raug zoo ntawm cov khoom, tab sis kuj txo qhov kev pheej hmoo ntawm cov kab nrib pleb thiab khoob.
Txhim kho adheesion
Txij li HEMC muaj cov yeeb yaj kiab zoo-tsim cov khoom, nws tuaj yeem tsim cov yeeb yaj kiab niaj hnub rau ntawm cov khoom siv adhesion ntawm cov khoom siv thiab cov txheej txheem. Cov cuab yeej no yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov xws li cov nplais nplaum thiab cov zaub mov, qhov uas nws tuaj yeem txhim kho durability thiab ruaj khov.
Txhim kho khov-thaw tsis kam
Hauv thaj chaw txias loj heev, khov-thaw ua cov khoom yog tshwj xeeb yog qhov tseem ceeb. HEMC txhim kho cov huab cua tsis kam ntawm cov khoom siv los ntawm kev ua kom zoo rau sab hauv cov khoom thiab melting dej thaum lub sijhawm khov-thaw.
4. Cov teeb meem raug nyob hauv cov ntawv thov
qhuav cug
Hauv cov tshuaj khib qhuav, hemc tsis yog kho kom cov dej ua haujlwm thiab ua haujlwm ntawm cov khoom siv tshuaj khib, tab sis kuj ua kom cov tshuaj khib yooj yim dua thiab cov duab thaum lub sijhawm tsim kho.
Cov kua nplaum
HEMC tuaj yeem txhim kho kev sib txuas lus cerloid hauv ceramic cov nplaum, kom muaj kev sib txuas ntawm cov nplais ceramic thiab cov substrates, thiab txo cov khoom npliag thaum tsim kho.
Putty hmoov
Ntawm cov hmoov muaj hmoov, hemc tuaj yeem txhim kho saum npoo smoothness, txhim kho cov dej tsis kam ntawm cov txheej, thiab ua kom lub putty txheej zoo dua hauv kev tsim kho tom ntej (xws li looj xim).
Hydroxyether Metherylulose tau dhau los ua qhov tsis tseem ceeb thiab tseem ceeb ntxiv hauv cov tsev ua kom zoo nkauj niaj hnub, dej ceev, lub zog thiab lwm yam khoom. Nws tsis yog tsuas txhim kho cov txheej txheem ntawm cov ntaub ntawv, tab sis kuj tseem ua tiav cov khoom lag luam thiab cov txiaj ntsig zoo rau cov neeg ua haujlwm thiab cov neeg siv. Nrog kev nce qib nruam kev siv thev naus laus zis, daim ntawv thov teb thiab cov teebmeem ntawm Hemc yuav nthuav ntxiv, muab kev pab ntxiv rau kev txhim kho kev tsim kho kev tsim kho.
