HPMC for Honeycomb Ceramics

I-HPMC, noma i-hydroxypropyl methylcellulose, iwuhlobo lwe-polymer esekelwe ku-cellulose esetshenziswe kuzinhlelo zokusebenza ezihlukahlukene, okuhlanganisa njengesibopho kuma-ceramics wekhekheba lezinyosi.I-ceramics yekhekheba lezinyosi iwuhlobo lwe-ceramic material eyakhiwe inethiwekhi yamaseli axhumene, angasetshenziswa ezinhlelweni ezihlukahlukene, njengezihlungi, ama-catalyst, nezishintshi zokushisa.I-HPMC iyisibopho esifanelekile sezitsha zobumba zoju ngenxa yamandla ayo aphezulu okubopha, izindleko eziphansi, kanye nokusebenziseka kalula.

I-HPMC iyi-polymer encibilika emanzini eyakhiwe ngama-molecule e-cellulose ashintshwe ngamaqembu e-hydroxypropyl.Lokhu kuguqulwa kwenza i-polymer incibilike kakhulu emanzini futhi kuyinikeza amandla okubopha aphezulu kunamanye ama-polymer asekelwe ku-cellulose.I-HPMC futhi izinze kakhulu futhi ingamelana namazinga okushisa aphezulu, iyenze ibe isibopho esifanelekile sezinto zobumba zoju lwezinyosi.

Uma isetshenziswa njengesihlanganisi kumakhekheba oju, i-HPMC ixutshwa nezinye izithako, njengobumba, i-silica, ne-alumina, ukuze kwakheke udaka.Lolu daka lube seluthelwa esikhunjeni bese luvunyelwa ukuba lome.Njengoba udaka loma, i-HPMC ihlanganisa ezinye izithako, yakhe i-ceramic yekhekheba lezinyosi eqinile futhi ehlala isikhathi eside.

I-HPMC iphinde isetshenziswe kwezinye izinhlelo zokusebenza, njengezinamathiselo, okokunamathela, nemikhiqizo yephepha.Kulezi zinhlelo zokusebenza, i-HPMC inikeza isibopho esiqinile phakathi kwezindawo ezimbili, okuyenza ibe ukukhetha okuhle kwemikhiqizo ehlukahlukene.

I-HPMC iyisibopho esisebenza ngezindlela eziningi futhi esingabizi kakhulu sezitsha zobumba zekhekheba lezinyosi.Kulula ukuyisebenzisa, inamandla okubopha aphezulu, futhi izinzile emazingeni okushisa aphezulu.I-HPMC futhi ayinabo ubuthi futhi ayihambisani nemvelo, okuyenza ibe ukukhetha okuhle kwezinhlelo zokusebenza ezihlukahlukene.
