Tshawb nrhiav seb Hydroxyethyl Cellulose (HEC) ua rau cov xim pleev xim zoo li cas, ruaj khov, thiab siv tau zoo li cas. Kawm txog cov kev coj ua zoo tshaj plaws rau kev tsim cov qauv thiab cov ntaub ntawv tshawb fawb hauv kev lag luam.

Piv HPMC nrog cov khoom ntxiv rau hauv cov plasters gypsum. Tshawb nrhiav seb HPMC txhim kho kev khaws dej, kev ua haujlwm tau zoo, thiab kev sib xws ntawm cov khoom kom ua tau zoo dua ntawm cov plaster.

Tshawb nrhiav seb vim li cas RDP thiaj ua tau zoo dua li cov tshuaj ntxiv latex ib txwm muaj hauv cov tshuab cementitious - txhim kho kev ruaj khov, kev txuag nqi, thiab cov txiaj ntsig zoo rau ib puag ncig.

Hydroxyethyl cellulose (HEC) yog ib qho polymer non-ionic uas siv tau ntau yam hauv kev lag luam xws li kev tsim kho, tshuaj, thiab tshuaj pleev ib ce vim nws cov khoom thickening thiab stabilizing zoo heev. Kev nkag siab txog cov yam ntxwv uas cuam tshuam rau viscosity ntawm HEC cov kev daws teeb meem yog qhov tseem ceeb rau kev ua kom zoo dua cov qauv thiab xyuas kom meej tias muaj kev ua haujlwm zoo sib xws.

Tshawb nrhiav seb yuav ua li cas Hmoov Polymer uas yaj tau dua (RDP) thiab Hydroxypropyl Methylcellulose (HPMC) ua haujlwm ua ke los txhim kho cov qauv mortar. Tsab xov xwm no piav qhia txog lawv lub luag haujlwm, cov txiaj ntsig, thiab cov teebmeem synergistic hauv kev txhim kho adhesion, elasticity, dej retention thiab durability hauv cov ntawv thov cement xws li cov nplaum rau pobzeb, cov tshuaj sib xyaw ua ke uas ua rau nws tus kheej sib npaug, thiab cov tshuaj nplaum uas tsis ntub dejKawm seb vim li cas kev xaiv qhov sib xyaw ua ke ntawm RDP thiab HPMC yog qhov tseem ceeb rau cov khoom siv mortar ua haujlwm siab.

Kawm paub xaiv qib HPMC zoo meej rau kev tsim kho, tshuaj, lossis zaub mov. Kawm paub txog qhov viscosity, purity, thiab kev xaiv hom kev hloov pauv nrog peb tus kws tshaj lij.

Puas muaj teeb meem xaiv qib CMC zoo? Kawm paub seb qhov viscosity, qib kev hloov pauv, thiab kev huv huv cuam tshuam li cas rau kev ua tau zoo hauv cov khoom siv av nplaum, khoom noj, tshuaj, thiab ntau ntxiv.

Tshawb nrhiav seb RDP txhim kho kev tuav dej thiab kev tiv thaiv kab nrib pleb li cas, ua rau cov putty phab ntsa zoo dua thiab txhim khu kev qha.

HPMC thiab MHEC yog ob qho tseem ceeb cellulose ethers siv rau hauv kev tsim kho thiab kev pleev xim, tab sis lawv txawv li cas? Tsab xov xwm no tshawb nrhiav qhov sib txawv tseem ceeb ntawm Hydroxypropyl Methylcellulose (HPMC) thiab Methyl Hydroxyethyl Cellulose (MHEC), suav nrog lawv cov khoom siv tshuaj lom neeg, kev khaws dej, kev muaj peev xwm ua kom tuab, thiab kev siv zoo tshaj plaws.
