HPMC rau Honeycomb Ceramics

HPMC, los yog hydroxypropyl methylcellulose, yog ib hom cellulose-raws li polymer uas tau siv nyob rau hauv ntau yam kev siv, xws li raws li ib tug binder nyob rau hauv honeycomb ceramics.Honeycomb ceramics yog ib hom khoom siv ceramic uas yog tsim los ntawm kev sib txuas ntawm cov hlwb sib txuas, uas tuaj yeem siv rau ntau yam kev siv, xws li cov ntxaij lim dej, catalysts, thiab cov khoom siv hluav taws xob.HPMC yog ib qho zoo tagnrho khi rau honeycomb ceramics vim nws lub zog ruaj khov, tsis tshua muaj nqi, thiab siv tau yooj yim.

HPMC yog cov dej-soluble polymer uas yog tsim los ntawm cellulose molecules uas tau hloov kho nrog hydroxypropyl pawg.Qhov kev hloov kho no ua rau cov polymer ntau dej-soluble thiab muab nws lub zog ruaj khov dua li lwm cov cellulose-based polymers.HPMC kuj tseem ruaj khov thiab tuaj yeem tiv taus qhov kub thiab txias, ua rau nws yog ib qho zoo tagnrho khi rau honeycomb ceramics.

Thaum siv los ua cov ntawv khi hauv honeycomb ceramics, HPMC yog tov nrog lwm cov khoom xyaw, xws li av nplaum, silica, thiab alumina, los tsim cov slurry.Cov slurry no ces nchuav rau hauv pwm thiab tso cai kom qhuav.Raws li cov slurry dries, HPMC khi lwm cov khoom xyaw ua ke, ua kom muaj zog thiab ruaj khov honeycomb ceramic.

HPMC kuj tseem siv tau rau lwm daim ntawv thov, xws li cov nplaum, txheej, thiab cov khoom siv ntawv.Hauv cov ntawv thov no, HPMC muab kev sib raug zoo ntawm ob qhov chaw, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam khoom.

HPMC yog ib qho khoom siv ntau yam thiab muaj txiaj ntsig zoo rau honeycomb ceramics.Nws yog ib qho yooj yim mus use, muaj ib tug siab binding zog, thiab yog ruaj khov nyob rau hauv high kub.HPMC kuj tsis muaj tshuaj lom thiab ib puag ncig tus phooj ywg, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv.
