Pobzeb Cov Ntawv Qhia Siv feem ntau siv nyob rau hauv kev tsim kho kev tsim kho kom tsim kev ua kom muaj zog thiab ntev-ntev ntawm cov vuas thiab substrates. Txawm li cas los xij, ua tiav kev nyab xeeb thiab ntev-ntev kev sib txuas lus ntawm cov vuas thiab substrates tuaj yeem nyuaj, tshwj xeeb yog yog qhov chaw tsis sib xws yog qhov tsis sib xws, paug lossis ntxeem tau.
Nyob rau hauv xyoo tsis ntev los no, kev siv ntawm hydroxypropylulose (HPMC) nyob rau hauv cov pobzeb nplaum tau dhau los ua nws cov khoom lag luam zoo tshaj plaws. HPMC yog cov multifunctional polymer muab tau los ntawm cellulose feem ntau siv los ua cov thickener, stabilizer thiab ncua thiab kev lag luam zoo nkauj thiab zaub mov noj. HPMC tseem muaj dav nyob rau hauv kev tsim kho kev tsim kho, tshwj xeeb tshaj yog nyob rau hauv cov vais nplaum, raws li nws cov viscosity siab ua tiav cov khoom sib khi ntawm cov vuas.
Txhim khu cov khoom siv hluav taws xob nplais hluav taws xob cov khoom siv uas siv cov viscosity high-viscosity HPMC
1. Txo cov dej nqus dej
Ib qho ntawm cov kev sib tw tseem ceeb hauv kev ua tiav qhov muaj zog ntawm cov nplais thiab substrate yog lub substrate dej, ua rau cov nplaum kom debond thiab swb. HPMC yog hydrophobic thiab pab txo cov dej nqus los ntawm cov txheej txheem. Thaum HPMC tau ntxiv rau cov txheej txheem nplais, nws ua cov txheej ntawm cov txheej txheem substrate uas tiv thaiv kev nkag mus thiab txo qhov kev pheej hmoo ntawm kev debond.
2. Txhim Kho Kev Ua Haujlwm
Ntxiv cov qib siab-viscosity HPMC rau Pobzeb nplaum tuaj yeem txhim kho kev tsim kho ntawm cov nplaum. Siab viscosity HPMC ua raws li cov tuab dua, muab cov nplaum kom zoo nkauj du thiab muaj kev ntxhib los mos. Qhov kev txhim kho no sib txawv ua rau nws siv tau yooj yim rau cov nplaum kom ua rau cov kev pheej hmoo, txo qhov kev pheej hmoo ntawm sagging lossis dripping thiab tsim kev sib raug zoo ntawm cov nplais thiab substrate.
3. Txhim Kho Adhesion
Siab viscosity HPMC tseem tuaj yeem txhim kho cov nplais khi los ntawm kev txhim kho cov khoom sib khi ntawm cov nplaum. Cov foos HPMC High-Viscosity HPMC muaj zog siv tshuaj nrog cov nplais nplaum thiab substrate, tsim kom muaj zog thiab txhim khu kev qha. Tsis tas li ntawd, cov khoom tuab tuab ntawm HPMC muab cov nplaum nrog cov khoom muaj peev xwm dua nrog cov khoom muaj peev xwm ntau dua, yog li kev txhim kho lub zog ntawm cov nyiaj txhwb.
4. Txo cov shrinkage
Cov nplaum tsis txaus yuav ua rau shrinkage, tawm ntawm qhov khoob ntawm cov nplais thiab substrate. Txawm li cas los xij, siab viscosity HPMC tuaj yeem pab txo kom txo qis shrinkage ntawm cov nplais nplaum los ntawm kev ua ib qho ruaj khov los ntawm kev ua kom ruaj khov thiab xwm yeem thaum daim ntawv thov. Txo cov shrinkage nce tag nrho cov nyiaj phia zog, kom ua kom ntev-ntev-ntev durability.
5. Txhim kho kev tawg
Ceramic vuas uas tsis zoo sib raug zoo rau lub substrate yog nquag mus tawg thiab tawg. Siab viscosity HPMC muaj cov tshuaj tiv thaiv zoo heev, pab tiv thaiv kom tsis txhob tawg thiab ua kom muaj qhov ntev ntawm cov nplais nplaum. HPMC muaj cai faib kev ntxhov siab, muab cov nyiaj sib yeem, thiab tiv taus cov kab rov tav thiab kab rov tav.
Hauv kev xaus
Siab viscosity HPMC ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov nplais nplais cov khoom, tshwj xeeb tshaj yog rau cov chaw sib tw. Ntxiv HPMC rau Pobzeb nplaum tuaj yeem txhim kho kev ua haujlwm, txhim kho cov nplaum thiab cov nplaum, thiab txhim kho qhov tawg tsis kam ntawm cov nplaum.
Nws yog tsim nyog teev tias HPMC yog ib puag ncig phooj ywg thiab tsis muaj tshuaj lom, ua rau nws xaiv cov tshuaj tiv thaiv ceramic rau ib puag ncig. Yog li ntawd, siv qib siab-viscosity HPMC nyob rau hauv cov pobzeb nplaum tsis tsuas yog txhim kho cov khoom zoo, tab sis kuj txhawb nqa ib puag ncig thiab kev nyab xeeb.
Kev tsim kho kev tsim kho tuaj yeem tau txais txiaj ntsig zoo los ntawm kev siv cov viscosity high-viscosity HPMC hauv cov nplais nplaum. Nws yog kev nyab xeeb, siv tau khoom zoo, siv tau yooj yim cov khoom sib khi ntawm cov vuas thiab substrate, ua kom ntev ntev. Los ntawm kev siv cov ntaub ntawv no, cov tib neeg tuaj yeem txaus siab rau kev siv lub zog ntev dua, cov nqi kho tus nqi qis dua, thiab tag nrho ib puag ncig kev ua phooj ywg.
