Daim ntawv thov ntawm HPMC:
Pobzeb Adhesive
● Kev tuav dej zoo: lub sijhawm qhib ntev yuav ua rau cov nplais ua haujlwm zoo dua.
● Txhim kho adhesion thiab zawv zawg tsis kam: tshwj xeeb tshaj yog rau cov vuas hnyav.
● Kev ua haujlwm zoo dua: lubricity thiab plasticity ntawm plaster yog guaranteed, mortar tuaj yeem siv tau yooj yim dua thiab sai dua.
Cement Plaster / Qhuav mix mortar
● Yooj yim kom qhuav cov mis vim yog dej txias solubility: pob tsim tuaj yeem zam tau yooj yim, zoo tagnrho rau cov vuas hnyav.
● Cov dej tuav tau zoo: tiv thaiv cov kua dej tsis zoo rau cov substrates, cov ntsiab lus dej tsim nyog tau khaws cia rau hauv qhov sib tov uas lav lub sijhawm ua kom ntev dua.
●Kev xav tau dej ntau ntxiv: qhib lub sijhawm qhib, nthuav dav spry cheeb tsam thiab kev tsim khoom siv nyiaj txiag ntau dua.
● Yooj yim sib kis thiab txhim kho sagging tsis kam vim kev txhim kho kev sib xws.
Phab ntsa putty
● Kev tuav dej: ua kom cov dej ntau tshaj hauv slurry.
●Anti-sagging: thaum kis lub tsho tuab tuab tuaj yeem zam tau.
●Ntau mortar tawm los: nyob ntawm qhov hnyav ntawm qhov sib tov qhuav thiab tsim tsim nyog, HPMC tuaj yeem ua kom lub ntim ntim ntau ntxiv.
Sab nrauv rwb thaiv tsev thiab Finish System (EIFS)
● Txhim kho adhesion.
● Muaj peev xwm ntub dej zoo rau EPS board thiab substrate.
● Txo cov cua nkag thiab dej nkag.
Self-leveling
● Kev tiv thaiv los ntawm dej exudation thiab cov khoom sedimentation.
● Tsis cuam tshuam rau slurry fluidity nrog tsawg viscosity
HPMC, thaum nws cov yam ntxwv tuav dej txhim kho qhov ua tiav ntawm qhov chaw.
Crack Filler
● Kev ua haujlwm zoo dua: cov thickness thiab plasticity.
● Kev tuav dej ua kom lub sijhawm ua haujlwm ntev.
●Sag kuj: txhim kho mortar bonding peev xwm.
