Lub luag haujlwm ntawm HPMC (hydroxypropyl methylcellulose) hauv cov nplais nplaum feem ntau suav nrog cov ntsiab lus hauv qab no:
Kev tuav dej: HPMC ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov dej tuav ntawm cov nplais nplaum. Nws tsim ib zaj duab xis rau saum npoo ntawm cov khoom, tiv thaiv kev nqus dej sai thiab tswj xyuas cov dej zoo sib xws rau cov dej kom zoo.
Thickener: HPMC ua raws li cov thickener, ua kom cov viscosity ntawm cov nplaum, uas txhim kho kev ua haujlwm thiab tiv thaiv cov vuas los ntawm sagging los yog zawv zawg thaum lub sijhawm teeb tsa.
Sijhawm qhib: Qhov sib ntxiv ntawm HPMC txuas ntxiv lub sijhawm qhib ntawm cov nplaum, muab sijhawm rau cov neeg teeb tsa thiab kho cov vuas ua ntej cov nplaum nplaum.
Txhim khu kev ruaj ntseg: HPMC txhim kho lub zog ntawm cov nplaum los ntawm kev txhawb nqa cov dej tsis sib xws ntawm cov cement hais, ua rau muaj kev sib raug zoo ntawm cov nplaum thiab cov substrate.
Flexibility: HPMC muab cov nplais nplaum ua kom yooj yim, txo qhov muaj peev xwm tawg vim qhov txav ntawm cov substrate lossis kub hloov pauv.
Adhesive cohesion: HPMC txhim khu kev sib koom ua ke ntawm cov nplaum, ua kom muaj kev sib raug zoo ntawm cov pobzeb thiab cov substrate.
Anti-sagging: HPMC lub thickening zog pab tiv thaiv cov vuas los ntawm sagging ntawm ntsug nto.
Txhim kho kev tsim kho: HPMC ua kom lub sijhawm tsim kho rau cov khoom xws li cement- thiab gypsum-based khoom, txo cov nqi zog, yog li txhim kho kev tsim kho kom zoo.
Txhim kho adhesion: HPMC txhim kho qhov adhesion ntawm cement- thiab gypsum-based khoom rau ntau yam substrates, nrog rau cov pob zeb, masonry, thiab cov vuas, yog li txo qhov kev pheej hmoo ntawm kev ua tsis tiav thiab tsis txhob muaj teeb meem kho tom qab.
Kev tswj hwm rheology zoo dua: HPMC ua rau cov khoom sib xyaw ua kua thiab ua rau nws tus kheej tsis muaj kev cuam tshuam rau nws txoj kev ruaj ntseg.
Txhim khu kev ruaj ntseg: HPMC txo cov dej ntsiab lus ntawm cov pob zeb sib tov, yog li txo qis kev siv cement thiab ib puag ncig.
HPMC ua lub luag haujlwm ntau yam hauv cov pobzeb nplaum, los ntawm kev txhim kho cov dej tuav thiab kev ruaj khov rau kev txhim kho cov khoom siv thiab kev ua kom yooj yim, txhua yam yog qhov tseem ceeb hauv kev ua kom cov pobzeb nplaum ua haujlwm thiab kev tsim kho zoo.
