Hauv kev tsim kho niaj hnub no, kev xaiv cov ntaub ntawv muaj feem cuam tshuam rau qhov zoo thiab tus nqi ntawm qhov project. Nyob rau hauv xyoo tas los no, MHEC (methylhydroxyethylcellulose) hmoov tau dhau los ua cov khoom siv nrov hauv kev tsim kho vim nws cov khoom tshwj xeeb thiab ntau yam.
Cov yam ntxwv tseem ceeb ntawm MHEC hmoov
MHEC yog cellulose ether compound tau los ntawm methylation thiab hydroxyethylation ntawm cellulose. Nws muaj dej solubility zoo heev, adhesion, thickening thiab stability, thiab yog dav siv nyob rau hauv lub tsev cov ntaub ntawv, xws li qhuav mortar, putty hmoov, pobzeb nplaum thiab sab nrauv phab ntsa rwb thaiv tsev systems.
Txhim kho kev tsim kho kev ua haujlwm
Txhim kho cov dej tuav: MHEC hmoov muaj cov khoom tuav dej zoo heev, uas tuaj yeem ua kom cov dej ntws tawm tau zoo, tso cai rau cov substrates xws li cement lossis gypsum kom muaj cov dej noo txaus thaum lub sij hawm hardening txheej txheem. Cov cuab yeej no pab txhim kho lub zog thiab kev sib txuas ntawm cov khoom siv thiab tiv thaiv kev tawg thiab shrinkage los ntawm kev poob dej.
Txhim khu kev ua haujlwm: Ntxiv MHEC hmoov rau mortars thiab putties tuaj yeem txhim kho lawv cov kev ua haujlwm thiab kev ua haujlwm zoo. Nyob rau hauv txoj kev no, cov neeg ua haujlwm tsim kho tuaj yeem ua haujlwm yooj yim dua, txo qhov nyuaj ntawm kev tsim kho thiab sijhawm, thiab txhim kho kev tsim kho kom zoo.
Txhim kho adhesion: MHEC hmoov tsim cov zaj duab xis nplaum tom qab ziab, uas txhim kho cov khoom adhesion thiab ua kom muaj kev sib raug zoo ntawm cov khoom siv hauv tsev. Qhov no yog ib qho tseem ceeb tshwj xeeb rau cov ntawv thov uas xav tau adhesion siab, xws li cov nplais nplaum nplaum thiab cov kab hluav taws xob sab nrauv.
Nqi-zoo
Txo cov nqi ntawm cov ntaub ntawv siv: Vim tias MHEC hmoov tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov khoom siv hauv paus, tus nqi ntawm lwm cov ntaub ntawv tuaj yeem raug txo rau hauv kev siv tswv yim. Piv txwv li, ntxiv MHEC hmoov rau mortar qhuav tuaj yeem txo cov cement thiab gypsum, yog li txo tus nqi tag nrho.
Txo cov sij hawm tsim kho: Kev siv MHEC hmoov tuaj yeem ua kom muaj kev tsim kho thiab txo lub sijhawm tsim kho, yog li txo cov nqi zog. Qhov txiaj ntsig no tshwj xeeb yog qhov tseem ceeb hauv kev tsim kho loj.
Txhim kho durability: Vim tias MHEC hmoov tuaj yeem txhim kho huab cua tiv thaiv thiab tawg tsis kam ntawm cov ntaub ntawv, nws ua rau cov tsev ruaj khov dua thiab txo qhov zaus thiab nqi kho thiab kho.
kev cuam tshuam ib puag ncig
Txo cov peev txheej siv: Kev siv MHEC hmoov tuaj yeem txo cov khoom siv tsim kho, yog li txo cov peev txheej siv. Tsis tas li ntawd, cellulose ether tebchaw feem ntau yog muab los ntawm cov nroj tsuag ntuj fibers thiab yog cov khoom siv txuas ntxiv dua tshiab, pab txo qis kev vam khom rau cov khoom siv tsis txuas ntxiv.
Txo cov pa phem ib puag ncig: MHEC hmoov tsis muaj tshuaj lom thiab tsis muaj zog, thiab yuav tsis tso cov pa phem thaum lub sijhawm tsim kho, txo cov kev puas tsuaj rau cov neeg ua haujlwm tsim kho thiab ib puag ncig.
Txhawb kev txhim kho kom ruaj khov: Los ntawm kev txhim kho kev ua tau zoo thiab ua haujlwm ntev ntawm cov khoom siv hauv tsev, MHEC hmoov pab txuas ntxiv kev pab cuam lub neej ntawm cov tsev, txo cov tsim cov khoom pov tseg, thiab txhawb kev txhim kho kom ruaj khov.
Daim ntawv thov
Hauv kev siv tswv yim, MHEC hmoov tau pom tias nws qhov kev ua tau zoo tshaj plaws hauv ntau qhov kev tsim kho. Piv txwv li, nyob rau hauv kev tsim kho ntawm ib tug loj coj mus muag complex, lub builder siv qhuav mortar nrog MHEC hmoov ntxiv, uas tsis tsuas yog txhim kho lub workability thiab bonding lub zog ntawm lub mortar, tab sis kuj ho txo lub sij hawm tsim kho thiab txuag tau ntau tus nqi. Tsis tas li ntawd, thaum lub sij hawm kev tsim kho ntawm sab nrauv phab ntsa rwb thaiv tsev, MHEC hmoov kuj qhia tau hais tias nws zoo heev dej tuav thiab huab cua tsis kam, ua kom lub sij hawm ntev stability ntawm lub rwb thaiv tsev txheej.
Kev siv MHEC hmoov hauv kev tsim kho tej yaam num muaj ntau yam zoo. Nws tuaj yeem tsis tsuas yog txhim kho kev tsim kho kev ua tau zoo thiab txo cov nqi, tab sis kuj txo cov kev cuam tshuam ib puag ncig thiab txhawb kev txhim kho kom ruaj khov. Nrog kev txhim kho txuas ntxiv ntawm kev tsim kho thev naus laus zis, daim ntawv thov kev cia siab ntawm MHEC hmoov hauv kev tsim kho yuav nthuav dav. Nyob rau hauv lub neej yav tom ntej, raws li qhov kev thov rau cov vaj tsev ntsuab thiab kev txhim kho kom ruaj khov, MHEC hmoov yuav ua lub luag haujlwm tseem ceeb zuj zus ntxiv raws li kev siv lub tsev zoo thiab ib puag ncig.
