Pobzeb nplaum feem ntau yog siv hauv kev tsim kho kev lag luam los tsim kom muaj kev sib raug zoo thiab ntev ntev ntawm cov vuas thiab substrates. Txawm li cas los xij, kev ua tiav kev ruaj ntseg thiab kav ntev ntawm cov vuas thiab cov substrates tuaj yeem nyuaj, tshwj xeeb tshaj yog yog tias lub substrate nto tsis sib luag, muaj kab mob los yog ntxeem tau.
Nyob rau hauv xyoo tas los no, kev siv hydroxypropyl methylcellulose (HPMC) hauv cov nplais nplaum tau ua nrov nrov vim nws cov khoom nplaum zoo heev. HPMC yog cov khoom siv ntau yam polymer muab los ntawm cellulose feem ntau siv los ua cov thickener, stabilizer thiab tshem tawm tus neeg sawv cev hauv kev lag luam tshuaj, tshuaj pleev ib ce thiab zaub mov. HPMC kuj tau siv dav hauv kev tsim kho kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov nplais nplaum, vim nws cov viscosity siab txhim kho cov khoom sib txuas ntawm cov vuas.
Txhim kho cov nplais pobzeb sib txuas cov khoom siv high-viscosity HPMC
1. Txo qhov nqus dej
Ib qho ntawm cov teeb meem tseem ceeb hauv kev ua tiav kev sib raug zoo ntawm cov pobzeb thiab cov substrate yog cov substrate absorbing dej, ua rau cov nplaum rau debond thiab ua tsis tiav. HPMC yog hydrophobic thiab pab txo cov dej nqus los ntawm substrate. Thaum HPMC ntxiv rau cov nplais nplaum, nws tsim ib txheej ntawm cov substrate uas tiv thaiv dej nkag thiab txo qhov kev pheej hmoo ntawm kev sib tsoo.
2. Txhim kho kev ua haujlwm
Ntxiv high-viscosity HPMC rau cov nplais nplaum tuaj yeem txhim kho kev tsim kho ntawm cov nplaum. High viscosity HPMC ua raws li cov thickener, muab cov nplaum ua kom du thiab zoo ib yam. Qhov kev txhim kho zoo sib xws no ua rau nws yooj yim dua rau kev siv cov nplaum rau hauv lub substrate, txo qhov kev pheej hmoo ntawm sagging los yog dripping thiab tsim kom muaj kev sib raug zoo ntawm cov pobzeb thiab substrate.
3. Txhim kho adhesion
High viscosity HPMC tuaj yeem txhim kho cov pobzeb sib txuas los ntawm kev txhim kho cov khoom sib txuas ntawm cov nplaum. High-viscosity HPMC tsim cov tshuaj lom neeg muaj zog nrog cov pobzeb nplaum thiab substrate, tsim kom muaj kev ruaj ntseg thiab txhim khu kev qha. Tsis tas li ntawd, cov khoom thickening ntawm HPMC muab cov nplaum uas muaj peev xwm thauj khoom ntau dua, yog li txhim kho qhov ruaj khov ntawm daim ntawv cog lus.
4. Txo shrinkage
Cov pobzeb nplaum tsis txaus tuaj yeem ua rau shrinkage, tawm hauv qhov sib txawv ntawm cov pobzeb thiab cov substrate. Txawm li cas los xij, siab viscosity HPMC tuaj yeem pab txo qis ntawm cov pobzeb nplaum los ntawm kev tsim kom muaj kev ruaj khov thiab zoo ib yam thaum siv. Txo shrinkage nce tag nrho daim ntawv cog lus muaj zog, kom ntseeg tau cov nplaum ntev ntev.
5. Txhim khu kev ua haujlwm tawg
Ceramic vuas uas tsis zoo sib txuas rau lub substrate yog qhov ua rau tawg thiab tawg. High viscosity HPMC muaj cov khoom zoo heev los tiv thaiv kev tawg, pab tiv thaiv kev tawg thiab ua kom lub neej ntev ntawm cov nplais nplaum. HPMC sib npaug faib cov kev ntxhov siab, muab kev sib raug zoo, thiab tiv thaiv txoj kab ntsug thiab kab rov tav.
nyob rau hauv xaus
High viscosity HPMC ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov pobzeb sib txuas, tshwj xeeb tshaj yog nyob rau ntawm qhov nyuaj. Ntxiv HPMC rau pobzeb nplaum tuaj yeem txhim kho kev ua haujlwm, txo cov dej nqus dej, txhim kho qhov adhesion ntawm cov khoom siv hauv paus thiab cov nplais nplaum, txo qis, thiab txhim kho qhov tawg ntawm cov nplaum.
Nws yog ib qho tsim nyog hais tias HPMC yog ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov phiaj xwm pobzeb ceramic hauv thaj chaw rhiab heev. Yog li ntawd, siv high-viscosity HPMC nyob rau hauv pobzeb adhesives tsis tsuas yog txhim kho cov nplaum zoo, tab sis kuj txhawb ib puag ncig sustainability thiab kev nyab xeeb.
Kev tsim kho kev lag luam tuaj yeem tau txais txiaj ntsig zoo los ntawm kev siv cov viscosity HPMC hauv cov nplais nplaum. Nws yog ib qho kev nyab xeeb, zoo, siv tau yooj yim cov khoom uas ntxiv dag zog rau kev sib raug zoo ntawm cov vuas thiab substrate, ua kom muaj kev ruaj ntseg ntev. Los ntawm kev siv cov khoom siv no, cov tib neeg tuaj yeem txaus siab rau kev ua kom ruaj khov, txo tus nqi tu, yooj yim ntawm kev siv, thiab tag nrho ib puag ncig tus phooj ywg.
