Cov khoom siv plaster thiab cov khoom siv plaster siv MHEC

MHEC (Methyl Hydroxyethyl Cellulose)yog ib qho cellulose ether compound siv dav hauv cov ntaub ntawv siv hauv kev tsim kho, suav nrog cov khoom xws li putty thiab plaster. Lub luag haujlwm ntawm MHEC hauv putty thiab gypsum feem ntau yog pom tseeb hauv kev ua kom tuab, khaws dej, thiab txhim kho kev ua haujlwm. Nws tuaj yeem txhim kho lawv cov kev ua tau zoo, ua rau kev tsim kho yooj yim dua, thiab ua rau cov khoom kawg zoo dua.

1. Kev ua tau zoo ntawm MHEC hauv putty

Cov khoom ua kom tuab

MHEC tuaj yeem ua rau kom cov putty viscosity thiab sib xws ntau dua, ua rau nws yooj yim dua rau kev siv thiab nthuav dav. Thaum lub sijhawm tsim kho, cov putty xav tau qhov sib xws kom sib xws kom sib npaug rau ntawm phab ntsa lossis lwm yam khoom siv. Los ntawm kev ua kom cov qauv sab hauv thiab kev ntws ntawm cov putty, MHEC ua rau nws tsis tshua muaj feem yuav poob thiab tswj tau qhov tuab thiab cov qauv sib xws txawm tias nyob hauv kev tsim kho ntsug.

Kev khaws dej

MHEC muaj cov yam ntxwv zoo uas khaws dej tau zoo thiab tuaj yeem kaw dej rau hauv cov putty kom tiv thaiv dej kom tsis txhob evaporate sai dhau. Qhov no tseem ceeb heev rau cov txheej txheem kho ntawm cov putty, vim tias yog tias cov dej noo poob ua ntej lub sijhawm, nws yuav ua rau cov putty ntsws thiab tawg lossis tsis muaj qhov nplaum txaus, yog li cuam tshuam rau qhov kawg ntawm kev tsim kho. Los ntawm kev ntxiv MHEC, cov putty tso cov dej noo sib npaug thaum lub sijhawm ziab, yog li txo cov qhov tsis zoo ntawm kev tsim kho thiab ntev lub sijhawm ua haujlwm ntawm cov putty, muab sijhawm ntau rau cov neeg ua haujlwm tsim kho los hloov kho thiab ua kom zoo dua.

Kev txhim kho kev tsim kho

Qhov rheology ntawm MHEC ua rau cov putty yooj yim dua rau kev siv thiab tuaj yeem txo qhov kev sib txhuam ntawm cov cuab yeej thiab cov khoom siv hauv qab, ua rau kev tsim kho nyuaj dua. Tsis tas li ntawd, qhov cuam tshuam ntawm MHEC ua rau cov putty du thiab yooj yim dua rau kev ua haujlwm thaum siv, uas tuaj yeem txhim kho kev ua haujlwm ntawm kev tsim kho thiab txo qhov yuam kev hauv kev tsim kho. Tib lub sijhawm, vim yog qhov ntxiv ntawm MHEC rau cov putty, qhov kev sib txuas ntawm cov putty tau txhim kho thiab cov txheej txheem sib txuas nruj dua tau tsim rau ntawm qhov chaw ntawm cov khoom siv hauv paus, yog li txhim kho qhov tiaj tus thiab kev ruaj khov ntawm cov khoom tiav.

2. Kev ua tau zoo ntawm MHEC hauv gypsum

Txhim kho plasticity thiab plasticity

Cov plaster yuav tsum yog yas txaus thaum siv kom tus neeg tsim kho tuaj yeem pwm nws mus rau hauv cov duab thiab tuab raws li xav tau. MHEC tuaj yeem txhim kho qhov plasticity ntawm gypsum los ntawm kev ua kom cov gypsum slurry sib xws, ua rau nws tsim nyog dua rau kev siv hauv cov qauv tsev nyuaj. Nws ua rau cov plaster yooj yim dua thaum siv, tswj kev sib npaug thiab ruaj khov txawm tias thaum siv rau thaj chaw loj dua.

Txuas sijhawm qhib

Cov gypsum khov sai sai, uas ua rau cov khoom qhuav thaum lub sijhawm tsim kho, ua rau kev ua haujlwm tom qab nyuaj. Los ntawm nws qhov kev khaws dej zoo heev, MHEC tuaj yeem ncua qhov kev ua pa ntawm cov dej hauv cov gypsum slurry, ncua lub sijhawm qhib ntawm gypsum, thiab muab sijhawm ntev rau cov neeg ua haujlwm tsim kho, yog li zam kev teeb meem ntawm kev hloov cov slurry ntau zaus. Tsis tas li ntawd, lub sijhawm qhib ntev tuaj yeem zam cov cim pom tseeb ntawm kev tsim kho splices thiab txhim kho qhov zoo ntawm kev tsim kho tag nrho.

Kev tiv thaiv tawg

MHEC ua rau gypsum tiv taus qhov tawg. Gypsum feem ntau yuav tawg vim yog dej ua pa sai sai thaum lub sijhawm kho. Qhov cuam tshuam ntawm MHEC uas khaws dej thiab ua kom tuab tuaj yeem ua rau qeeb qeeb ntawm kev tso dej tawm thiab tiv thaiv kev qhuav thiab tawg vim yog poob dej tam sim ntawd. Tsis tas li ntawd, qhov tawv ntawm MHEC kuj tseem tuaj yeem txhim kho qhov yooj ywm ntawm gypsum, ua rau nws hloov tau yooj yim dua rau kev hloov pauv me ntsis, yog li tiv thaiv tau qhov tshwm sim ntawm cov tawg.

Txhim kho qhov chaw tiav

Qhov saum npoo ntawm gypsum ntxiv nrog MHEC yuav du thiab mos dua tom qab kho. Cov zaj duab xis nplaum tsim los ntawmMHECntawm qhov chaw gypsum pab ua kom qhov chaw gypsum huv si thiab du, txo qhov tshwm sim ntawm cov npuas thiab cov pob khaus, thiab ua rau cov khoom tiav zoo nkauj thiab zoo nkauj dua. Tib lub sijhawm, plaster nrog qhov chaw du kuj tseem zoo dua rau kev pleev xim tom qab, ua rau cov nyhuv kho kom zoo nkauj zoo dua.

3. MHEC cov txiaj ntsig zoo hauv putty thiab gypsum

Tiv thaiv kev qaug zog

MHEC muab cov khoom zoo tiv thaiv kev poob qis rau cov putty thiab gypsum slurry, tshwj xeeb tshaj yog tsim rau kev tsim kho ntsug lossis saum npoo, ua rau cov khoom siv tsis tshua muaj kev ntws lossis poob, ua rau kev tsim kho ruaj ntseg dua thiab cov txiaj ntsig kav ntev dua.

Txhim kho kev tsim kho kom zoo dua

MHEC txhim kho kev ua tau zoo ntawm cov putty thiab gypsum, tsis yog tsuas yog ua rau cov txheej txheem tsim kho du dua xwb, tab sis kuj txo qhov ua tau ntawm kev rov ua dua, yog li txhim kho kev ua haujlwm zoo ntawm kev tsim kho.

kev ruaj khov

MHEC muaj kev ruaj khov tshuaj zoo, tuaj yeem hloov kho rau ntau yam huab cua thiab qhov kub thiab txias, thiab tuaj yeem tswj tau kev ua haujlwm zoo ntawm qhov kub siab lossis qis, ua rau putty thiab gypsum siv dav dua.

Kev tiv thaiv ib puag ncig

MHEC yog ib yam khoom siv uas tsis ua rau muaj teeb meem thaum lub sijhawm tsim kho. Tib lub sijhawm, nws txoj kev ua haujlwm zoo txo ​​cov putty thiab gypsum, txo cov khoom pov tseg, thiab ua tau raws li cov kev xav tau ntawm cov tsev niaj hnub uas tsis ua rau muaj teeb meem.

Ua ib qho tshuaj ua kom tuab thiab khaws dej tau zoo, MHEC tau ua pov thawj tias muaj txiaj ntsig zoo hauv kev ua putty thiab plaster. Nws tuaj yeem txhim kho qhov zoo ntawm kev tsim kho ntawm putty thiab gypsum thiab cov txiaj ntsig ntawm cov khoom kawg los ntawm ntau yam haujlwm xws li ua kom tuab, khaws dej, thiab txhim kho kev ua haujlwm tau zoo. Qhov ntau yam ntxwv no ua rau MHEC nrov heev hauv kev lag luam kev tsim kho, tshwj xeeb tshaj yog hauv cov haujlwm uas xav tau kev tsim kho zoo thiab ruaj khov. Yav tom ntej, nrog rau kev txhim kho thev naus laus zis kev tsim kho tas mus li, MHEC yuav siv dav dua hauv putty thiab gypsum, thiab nws cov kev ua tau zoo yuav raug kho kom zoo dua thiab txhim kho ntxiv.
