Cov pobzeb nplaum tau siv dav los txhim kho cov vuas ntawm ntau qhov chaw xws li phab ntsa thiab hauv pem teb. Lawv yog ib qho tseem ceeb kom ntseeg tau tias muaj kev sib raug zoo ntawm cov pobzeb thiab cov substrate kom tsis txhob muaj kev puas tsuaj, thiab xyuas kom meej tias lub installation tuaj yeem tiv taus ntau yam kev ntxhov siab xws li av noo, kub hloov thiab tu tsis tu ncua.
Ib qho ntawm cov khoom xyaw uas nquag siv hauv cov nplais nplaum yog hydroxypropylmethylcellulose (HPMC), ib qho polymer feem ntau muab los ntawm cellulose. Nws yog lub npe hu rau nws lub peev xwm zoo khaws cia dej, uas ua rau nws muaj qhov zoo tshaj plaws hauv cov pobzeb nplaum formulations.
Muaj ntau qhov zoo rau kev siv HPMC hauv cov ntawv nplaum nplaum. Cov no suav nrog;
1. Txhim kho kev ua haujlwm
HPMC ua raws li kev hloov kho rheology hauv cementitious formulations xws li pobzeb adhesives, uas txhais tau hais tias nws tuaj yeem txhim kho kev ua haujlwm ntawm cov nplais nplaum. Nws kuj txo cov tsos mob ntawm cov pob qij txha thiab cov hlab ntsha, uas txhim kho qhov sib xws ntawm cov khoom sib xyaw, ua kom yooj yim rau cov neeg tsim khoom ua haujlwm nrog.
2. Kev tuav dej
Ib qho ntawm qhov zoo ntawm HPMC hauv cov nplais nplaum yog nws cov dej tuav tau zoo heev. Nws ua kom ntseeg tau tias cov nplaum nplaum tseem siv tau rau lub sijhawm ntev thiab pab cov pobzeb nplaum teeb. Qhov no feature kuj txo qhov kev pheej hmoo ntawm shrinkage tawg, uas feem ntau tshwm sim los ntawm kev poob dej thaum lub sij hawm teeb tsa.
3. Muaj zog ntxiv
Lwm qhov txiaj ntsig ntawm kev siv HPMC hauv cov nplais nplaum yog tias nws pab ua kom lub zog ntawm kev sib xyaw. Qhov sib ntxiv ntawm HPMC pab txhim kho qhov sib tov, ntxiv dag zog thiab txhim kho tag nrho cov kav ntev ntawm cov nplais nplaum.
4. Txuag sijhawm
Pobzeb nplaum uas muaj HPMC yuav tsum muaj tsawg dua kev sib xyaw ua ke thiab lub sijhawm thov vim kev txhim kho rheology. Tsis tas li ntawd, lub sijhawm ua haujlwm ntev dua uas tau muab los ntawm HPMC txhais tau hais tias cov cheeb tsam loj tuaj yeem raug them, ua rau cov pobzeb txhim kho sai dua.
5. Txo kev cuam tshuam ib puag ncig
HPMC yog cov khoom ntuj tsim thiab biodegradable. Yog li, kev siv HPMC hauv cov nplais nplaum tuaj yeem txo cov nplaum nplaum ib puag ncig thiab ua tau raws li qhov xav tau loj hlob rau cov khoom siv hauv tsev.
Hauv cov ntsiab lus, HPMC yog qhov tseem ceeb hauv kev tsim cov nplais nplaum zoo. Nws lub peev xwm tuav dej thiab txhim kho rheological muab cov txiaj ntsig suav nrog kev txhim kho kev ua haujlwm, muaj zog ntxiv, txo kev cuam tshuam ib puag ncig thiab txuag lub sijhawm. Yog li ntawd, qee cov pobzeb nplaum manufacturers tau siv HPMC los txhim kho pobzeb daim ntawv cog lus lub zog thiab ua rau kom muaj zog ntawm lawv cov nplaum.
