Nws cov qauv khoom muaj ntau yam thiab tuaj yeem siv rau cov tshuab mortar hauv ntau yam kev tsim kho, tshwj xeeb tshaj yog cov ntaub ntawv gypsum. Nws muaj ntau yam txiaj ntsig ntawm kev siv.

2. Kev ua tau zoo thiab lub luag haujlwm hauv gypsum mortar

2.1. Txhim kho kev khaws dej thiab tiv thaiv kev poob dej thiab tawg thaum ntxov

Cov ntaub ntawv gypsum tawv sai, thiab thaum lub sijhawm tsim kho, nws yooj yim poob dej sai dhau vim yog dej nqus los ntawm lub hauv paus lossis evaporation los ntawm ib puag ncig, ua rau muaj kab nrib pleb thiab kev sib txuas tsis zoo. AnxinCel® HPMC tuaj yeem tsim cov qauv sib txuas sib npaug thiab ruaj khov hauv cov mortar, ua kom cov dej noo zoo thiab txhim kho kev khaws dej. Cov txiaj ntsig ntawm kev ua tau zoo ntawm kev khaws dej suav nrog:

Xyuas kom meej tias cov tshuaj tiv thaiv dej ntawm gypsum thiab txhim kho lub zog;

Txo cov kab nrib pleb uas tshwm sim los ntawm kev poob dej thiab kev ntsws;

Txhim kho qhov kev sib txuas nrog lub hauv paus.

2.2. Txhim kho kev ua haujlwm ntawm kev tsim kho thiab lub sijhawm ua haujlwm

AnxinCel® HPMC kho qhov sib xws thiab kev ntws ntawm cov mortar kom muab cov mortar zoo dua thiab ua haujlwm du. Tshwj xeeb, nws yog qhia raws li:

Ua kom lubricity nce thiab txo qhov kev tsim kho tsis kam;

Ntev lub sijhawm ua haujlwm kom yooj yim rau cov neeg ua haujlwm tsim kho kom hloov kho tau;

Tiv thaiv kom tsis txhob sagging thiab dripping, tshwj xeeb tshaj yog haum rau kev tsim phab ntsa lossis qab nthab.

Qhov kev ua tau zoo no yog qhov tseem ceeb rau kev tsim kho loj thiab kev tsim kho hauv qhov chaw kub thiab qhuav, uas tuaj yeem txhim kho kev ua haujlwm thiab txo qhov rov ua haujlwm.

2.3. Kho qhov sib xws thiab thixotropy kom txhim kho kev ua haujlwm tiv thaiv kev sagging

AnxinCel® HPMC muaj thixotropy tseem ceeb, uas yog, qhov viscosity txo qis thaum do lossis pressurizing, thiab sai sai rov qab mus rau nws lub xeev qub tom qab tsis txhob do. Cov khoom no ua rau cov kua gypsum mortar thaum lub sijhawm tsim kho, thiab nws tsis yooj yim ntws lossis poob tom qab txuas rau ntawm phab ntsa, uas ua rau qhov yooj yim thiab zoo ntawm kev tsim kho facade zoo dua.

2.4. Txhawb kom muaj kev sib xyaw thiab kev ruaj khov zoo ib yam

HPMC muaj kev ua haujlwm ntawm qhov chaw thiab tuaj yeem ua lub luag haujlwm faib tawm thaum lub sijhawm sib tov, yog li ntawd ntau yam khoom sib xyaw hauv cov mortar qhuav tau sib xyaw ua ke ntau dua, zoo tiv thaiv kev faib tawm thiab kev sib cais ntawm cov ntaub ntawv. Nws cov qauv molecular ruaj khov kuj tseem tuaj yeem txhim kho kev ruaj ntseg ntawm kev khaws cia ntawm gypsum mortar thiab zam kev dej ntws thiab teeb meem sedimentation.

2.5. Txhim kho qhov lo thiab qhov zoo ntawm qhov chaw

Yog siv AnxinCel® HPMC kom txaus, nws yuav ua rau lub zog sib txuas ntawm cov gypsum mortar thiab lub hauv paus lossis cov khoom siv npog zoo dua, uas pab kom cov mortar sib haum zoo tom qab ua tiav thiab tsis yooj yim poob. Tib lub sijhawm, nws txoj kev txhim kho cov khoom rheological ntawm cov slurry kuj pab ua kom qhov chaw tiaj tus thiab du tom qab siv, ua rau cov khoom tiav zoo dua.

3. Cov lus qhia txog kev siv tshuaj thiab kev siv

Feem ntau, cov tshuaj AnxinCel® HPMC uas pom zoo kom siv rau hauv cov gypsum mortar yog 0.1% ~ 0.3% (hauv cov hmoov qhuav). Cov tshuaj no yuav tsum tau hloov kho raws li tus qauv khoom, qhov chaw tsim kho, thiab cov qauv ntawm cov mortar. Txoj kev ntxiv yog sib tov qhuav nrog lwm cov hmoov qhuav kom ntseeg tau tias kev sib tov sib npaug.

Daim ntawv thov AnxinCel® HPMC hauv gypsum mortartuaj yeem txhim kho nws cov khoom tseem ceeb xws li kev khaws dej, kev ua haujlwm tau zoo, thixotropy, tiv thaiv kev sagging thiab kev nplaum. Raws li kev tsim kho niaj hnub no ua rau muaj kev thov ntau dua rau kev ua haujlwm ntawm cov mortar, HPMC, ua cov khoom siv ntsuab, zoo rau ib puag ncig thiab ua haujlwm tau zoo, tab tom dhau los ua qhov tseem ceeb thiab tseem ceeb hauv cov qauv gypsum mortar. Kev vam khom rau cov thev naus laus zis R&D siab heev thiab kev tswj hwm zoo nruj, lub npe AnxinCel® muab cov kev daws teeb meem ruaj khov thiab txhim khu kev qha rau kev ua haujlwm zoo ntawm cov khoom gypsum mortar.
