Cov Kev Siv Ib Txwm ntawm HPMC
Cov nplaum pobzeb
● Khaws dej tau zoo: lub sijhawm qhib ntev yuav ua rau cov vuas vuas ua haujlwm tau zoo dua.
● Txhim kho kev nplaum thiab kev tiv thaiv kev swb: tshwj xeeb tshaj yog rau cov vuas hnyav.
● Ua haujlwm tau zoo dua: ua kom cov plaster muaj roj thiab plasticity, siv tau yooj yim dua thiab sai dua.
Cov Cement Plaster / Cov av sib xyaw qhuav
● Cov mis sib tov yooj yim qhuav vim nws yaj tau hauv dej txias: yooj yim zam kev ua pob, zoo tagnrho rau cov vuas hnyav.
● Khaws dej zoo: tiv thaiv kev poob dej rau cov substrates, cov dej kom zoo khaws cia rau hauv cov khoom sib xyaw uas lav lub sijhawm ntev dua.
● Xav tau dej ntau ntxiv: lub sijhawm qhib ntev dua, thaj chaw tsuag dav dua thiab cov mis tshuaj pheej yig dua.
● Yooj yim nthuav dav thiab zoo dua qub tiv taus kev poob vim muaj kev sib xws zoo dua.
Cov khoom siv pleev rau phab ntsa
● Kev khaws dej: cov dej ntau tshaj plaws hauv cov slurry.
●Tiv thaiv kev qig: thaum nthuav cov txheej tuab dua, yuav zam tau kev sib txhuam.
● Cov khoom siv mortar ntau ntxiv: nyob ntawm qhov hnyav ntawm cov khoom sib tov qhuav thiab cov mis tsim nyog, HPMC tuaj yeem ua rau cov khoom siv mortar ntau ntxiv.
Kev rwb thaiv tsev sab nraud thiab lub kaw lus tiav (EIFS)
● Kev nplaum zoo dua.
●Muaj peev xwm ntub dej zoo rau EPS board thiab substrate.
● Txo qhov cua nkag thiab dej nqus.
Kev ntsuas tus kheej
● Kev tiv thaiv kom tsis txhob muaj dej tawm thiab cov khoom poob rau hauv av.
●Tsis muaj kev cuam tshuam rau cov kua dej ntawm cov slurry nrog cov viscosity qis
HPMC, thaum nws cov yam ntxwv khaws cia dej txhim kho qhov kev ua tiav ntawm qhov chaw.
Cov Khoom Siv Rau Qhov Tawg
● Ua haujlwm tau zoo dua: tuab thiab plasticity kom raug.
● Kev khaws dej ua kom lub sijhawm ua haujlwm ntev.
●Kev tiv thaiv kev poob qis: txhim kho lub peev xwm sib txuas ntawm cov mortar.
