Putty hmoov yog ib qho siv tau siv rau phab ntsa leveling, ntim cov kab nrib pleb, ntim cov kab nrib pleb thiab muab cov xim du rau cov duab txuas ntxiv thiab kho kom zoo nkauj. Cellulose ether yog ib qho ntawm cov quav tseem ceeb hauv kev tsim kho kom zoo, uas tuaj yeem txhim kho kev tsim kho kev tsim kho thiab kev ua tau zoo ntawm cov hmoov. Kab lus no yuav qhia tau meej rau kev nthuav dav cov ntaub ntawv tshwj xeeb ntawm cov neeg muaj kev pab cuam cellulose hauv putty hmoov thiab nws tseem ceeb rau kev tsim kho kev tsim kho.
1. Cov khoom yooj yim thiab cov haujlwm ntawm cov cellulose muaj cov neeg muaj cai
Cellulose ether yog hom dej-soluble polymer compound siv tshuaj lom neeg siv cov khoom siv ntuj. Nws cov qauv molecular muaj ntau cov pab pawg hydrophilic (xws li hydroxyl, metchot, thiab lwm yam muaj peev xwm. Hauv kev thov ntawm cov hmoov putty, lub luag haujlwm tseem ceeb ntawm cellulose ether yog feem ntau los ntawm cov hauv qab no:
Thickening nyhuv
Cellulose ether tuaj yeem ua kom cov putcosity ntawm putty hmoov slurry, ua rau nws muaj qhov zoo thixotropy thiab ruaj khov, yog li yooj yim, yog li yooj yim, yog li yooj yim siv. Tsis tas li ntawd, nws tseem tuaj yeem hloov kho cov pob zeb rheological ntawm cov slurry kom tiv thaiv cov hmoov uas muaj dej ntws los yog zawv zawg ntawm cov phab ntsa, ua kom muaj kev txhim kho kom huv ntawm kev tsim kho.
Dej ceev
Lub dej siab khaws cia ntawm cellulose ether yog ib qho ntawm nws cov yam ntxwv tseem ceeb thaum siv hauv hmoov ua kom muaj sia. Thaum lub sij hawm tsim kho, tom qab cov hmoov putty yog thov rau ntawm phab ntsa, lub evaporation ntawm dej yuav ua rau cov hmoov puty kom qhuav thiab tev. Cellulose ether muaj peev xwm ncua sij hawm poob dej, ua rau kom qhuav thiab ua kom qhuav, thiab ua kom muaj kev sib tsoo ntawm phab ntsa.
Txhim Kho Kev Ua Haujlwm
Lub xub ntiag ntawm cellulose ether ho txhim kho kev tsim kho cov khoom tsim kev tsim khoom ntawm cov hmoov putty. Piv txwv li, nws tuaj yeem txhim kho kev hloov pauv ntawm kev siv zaub mov, ua rau nws yooj yim dua rau cov neeg ua haujlwm los txhuam cov neeg mob uas muaj zog. Tsis tas li ntawd, cellulose ether kuj tuaj yeem txo cov tiam ntawm cov npuas ntawm lub ntsej muag ci thiab txhim kho qhov zoo nkauj, yog li txhim kho cov nyhuv zoo nkauj.
Ncua Sijhawm Qhib Sijhawm
Hauv kev tsim kho, lub sijhawm qhib ntawm putty hmoov, uas yog, lub sijhawm los ntawm kev thov kom ziab thiab solidification ntawm cov neeg ua haujlwm ua haujlwm tau zoo mloog. Cellulose ether tuaj yeem txuas lub sij hawm qhib cia, txo pob qij txha thaum tsim kho, yog li kev txhim kho lub nroog zoo nkauj ntawm phab ntsa.
2. Daim ntawv thov ntawm cellulose ether nyob rau hauv txawv scararios ntawm putty hmoov
Sab hauv phab ntsa swb
Nyob rau hauv daim ntawv thov ntawm phab ntsa sab hauv Putty, cellulose ether tsis tsuas yog kho kom muaj zog, tab sis kuj tseem tuaj yeem hloov kho kom zoo nkauj thiab nplaum ntawm phab ntsa saum npoo av. Tsis tas li ntawd, cov dej siab rov ua tau zoo ntawm cellulose ether tuaj yeem tiv thaiv kom muaj kev tawg ntawm cov txheej txheem ntawm cov ntaub ntawv thov kom ntev nyob hauv cov chaw qhuav huv.
Phab ntsa sab nrauv pov tseg
Phab Ntsa Sab Nrauv Putty xav tau huab cua tsis kam thiab tawg tawm tsam los ntawm phab ntsa sab nrauv yuav raug cuam tshuam los ntawm kev nyab xeeb, sib txawv thiab lwm yam. Daim ntawv thov ntawm cellulose ether nyob sab nraud phab ntsa ntub dej tuaj yeem txhim kho nws cov dej tsis kam txhim kho kom hloov pauv ntawm ib puag ncig sab nraud thiab txuas ntxiv nws lub neej pabcuam. Ib qho ntxiv, cellulose ether kuj tseem tuaj yeem txhim kho nws cov UV tsis kam thiab lwm yam khoom, yog li ntawd tus kheej sab nrauv lub cev muaj peev xwm ua tau ruaj khov lub zog.
waterproof putty
Waterproof Putty yog haum rau cov av noo ib puag ncig xws li chav dej thiab chav ua noj, thiab yuav tsum tau waterproofness thiab dej tsis kam ntawm lub putty. Cellulose ether tuaj yeem txhim kho qhov tsis muaj dej ntawm cov putty ntawm ensuring nws cov adhesion zoo thiab ua haujlwm. Tsis tas li ntawd, cov thickening thiab dej-khaws cov kev cuam tshuam ntawm cellulose ntawm cellulabe cellulabe nyob rau hauv ib puag ncig muaj cov teeb meem vaum thiab tsis txhob muaj teeb meem cov teeb meem mildew rau ntawm phab ntsa.
High-xaus decorative putty
High-xaus dai kom zoo nkauj Putty muaj cov kev xav tau zoo heev thiab zoo kawg nkaus, thiab feem ntau yog siv nyob rau hauv high-endels thiab lwm qhov chaw. Cellulose ether tuaj yeem pab ua kom cov khoom siv kom yooj yim, txhim kho cov khoom siv kom zoo dua, ua kom cov khoom siv kho kom zoo dua, thiab ua tau raws li qhov kho kom zoo dua ntawm cov chaw siab.
3. Kev xaiv ntawm cellulose ether hauv putty hmoov
Raws li daim ntawv thov xav tau thiab cov kev xav tau ntawm cov hmoov puTty, cov cellulose cellulose feem ntau siv hauv kev tsim kho:
HydroxyPropyyl methylcellulose (HPMC)
HPMC yog ib qho kev tsim kho uas ib txwm siv tau ntxiv nrog cov dej ua kom zoo thiab ua kom tuab. Nws yog dav siv nyob rau hauv cov ntaub ntawv hauv tsev xws li phab ntsa sab nrauv Putty, pobzeb cov khoom sib xyaw, thiab cov plastering mortars. Nws tuaj yeem txhim kho cov sag tiv thaiv thiab ua haujlwm ntawm hmoov putty, thiab tshwj xeeb tshaj yog tsim nyog rau cov kev xav tau ntawm high-viscosity putty.
Hydroxyethylmethylcellose (HEMC)
HEMC muaj dej zoo khaws cia kev ua tau zoo thiab ruaj khov, tshwj xeeb tshaj yog nyob rau hauv tsawg solubility, yog li nws yog haum rau kev siv nyob rau sab nrauv phab ntsa putty. Ntxiv rau, hemc muaj cov txiaj ntsig zoo heev rau kev txhim kho cov dispersion thiab kev sib xws ntawm cov hmoov putty, ua rau saum npoo smoother thiab smoother tom qab txheej.
Carboxymethyl cellulose (cmc)
CMC yog cov dej tuab. Txawm hais tias nws muaj dej tsawg tuav thiab tiv thaiv cov khoom siv los tiv thaiv, nws tus nqi yog tsawg. Nws feem ntau siv nyob rau hauv putty hmoov uas tsis tas yuav siv dej siab thiab yog haum rau kev siv sab hauv phab ntsa putty.
4. Cov zeem muag thiab cov ncauj lus ntawm cellulose muaj kev pab cuam hauv lub putty hmoov kev lag luam
Nrog kev txhim kho kev tsim kho ntawm kev tsim kho, tib neeg txoj cai kev tiv thaiv tau maj mam nce, thiab daim ntawv thov kev pab cuam uas muaj kev cuam tshuam ntawm cellulose muaj cov neeg muaj kev pab cuam cellulose tau dhau los ua kom dav. Hauv kev txhim kho yav tom ntej ntawm kev lag luam muaj putty, daim ntawv thov ntawm cellulose ether yuav tsom mus rau qhov hauv qab no:
Ntsuab thiab ib puag ncig phooj ywg
Tam sim no, ib puag ncig cov ntaub ntawv hauv tsev yog cov ncauj lus kub hauv kev tsim kho. Ua cov khoom siv polymer tau los ntawm cov xov tooj ntawm ntuj, cellulose ether conforms rau lub tswv yim ntawm kev tiv thaiv ntsuab ib puag ncig thiab tuaj yeem txo cov pa phem kho kom zoo nkauj. Yav tom ntej, ntau-voc (volatile organic sib txuas) thiab kev ua tau zoo cellulose khoom siv yuav raug tsim kho thiab thov.
Txuag thiab ntse
Kev txhim kho cellule txuas ntxiv ether tuaj yeem ua kom hmoov pilty kom tswj tau ruaj khov chaw nyob hauv ib puag ncig. Piv txwv li, los ntawm cov qauv molecular kev ua kom zoo thiab ntxiv rau cov khoom sib ntxiv, cov hmoov kom muaj zog dua thiab kho cov ntaub ntawv ua kom zoo dua thiab muaj txiaj ntsig.
Versatility
Thaum txhim kho cov khoom tseem ceeb ntawm cov hmoov putty, cellulose hais kom muaj zog xws li cov tshuaj tua kab mob xws li cov kev xav tau ntawm cov kev xav tau tshwj xeeb tshaj plaws.
Daim ntawv thov ntawm cellulose ether hauv putty hmoov tsis yog ua kom zoo nkauj ntawm phab ntsa kom zoo nkauj, tab sis kuj tseem ua kom muaj kev ua kom zoo nkauj rau phab ntsa tiaj tiaj, smortness thiab durability. Cov. Nrog kev tsim kho tas mus li ntawm kev tsim kho kev tsim kho, kev siv cellulais cov hmoov putty yuav dhau los thiab muaj ntau lub tsev kev ua tau zoo thiab ib puag ncig kev tiv thaiv.
