Dab tsi yog lub luag haujlwm ntawm hydroxypropyl methylcellulose (HPMC) hauv diatom av nkos?
Hydroxypropyl methylcellulose (HPMC) feem ntau yog siv los ua ib qho ntxiv hauv diatom av nkos, uas yog ib hom kev kho kom zoo nkauj phab ntsa txheej ua los ntawm diatomaceous ntiaj teb. HPMC ua haujlwm rau ntau lub luag haujlwm hauv diatom av formulations:
- Kev tuav dej: HPMC muaj cov khoom tuav dej zoo heev, pab tiv thaiv kom tsis txhob ziab ntxov ntawm cov av nkos thaum siv. Qhov no ua kom lub sijhawm ua haujlwm ntev dua thiab tso cai rau kom zoo dua adhesion rau substrate.
- Thickening: HPMC ua raws li tus neeg sawv cev thickening nyob rau hauv diatom av formulations, txhim kho cov viscosity ntawm cov sib tov. Qhov no txhim khu kev ua haujlwm ntawm cov av nkos, ua rau nws yooj yim dua los thov tusyees ntawm cov phab ntsa thiab tsim kom muaj qhov zoo nkauj ntawm qhov chaw.
- Kev khi: HPMC pab txhawm rau khi ntau yam ntawm cov av nkos diatom ua ke, txhawb kev sib koom ua ke thiab tiv thaiv sagging lossis slumping thaum thov. Qhov no ua kom cov av nkos adheres zoo rau ntawm phab ntsa nto thiab tuav nws cov duab kom txog thaum nws qhuav.
- Txhim kho Adhesion: Los ntawm kev txhim kho cov nplaum nplaum ntawm cov av nkos diatom, HPMC pab txhim kho kev sib raug zoo ntawm cov av nkos thiab cov substrate. Qhov no ua rau cov phab ntsa ruaj khov thiab ntev ntev uas tsis tshua muaj kev tawg lossis tev tawm thaum lub sijhawm.
- Zaj duab xis tsim: HPMC pab txhawb rau kev tsim cov yeeb yaj kiab nyias ntawm cov av nkos diatom thaum nws qhuav. Cov yeeb yaj kiab no pab kaw cov nplaim, txhim kho dej tsis kam, thiab txhim kho qhov tsos ntawm phab ntsa tag nrho.
- Stabilization: HPMC pab txhim kho cov diatom av nkos formulation, tiv thaiv sedimentation thiab sib cais ntawm cov khoom xyaw raws sij hawm. Qhov no ua kom zoo ib yam thiab sib xws hauv cov khoom ntawm cov av nkos thoob plaws hauv nws lub neej txee.
HPMC ua lub luag haujlwm tseem ceeb hauv kev tsim cov diatom av nkos los ntawm kev txhim kho cov dej tuav, thickening sib tov, txhim kho adhesion thiab durability, thiab pab txhawb rau tag nrho cov zoo ntawm cov tiav phab ntsa txheej.
