HPMC for Honeycomb Ceramics

I-HPMC, okanye i-hydroxypropyl methylcellulose, luhlobo lwepolymer esekwe kwi-cellulose esetyenzisiweyo kwizicelo ezahlukeneyo, kubandakanywa njenge-binder kwi-honeycomb ceramics. I-Honeycomb Ceramics luhlobo lwemathiriyeli ye-ceramic eyenziwe yinethiwekhi yeeseli ezidibeneyo, ezinokuthi zisetyenziswe kwiintlobo ezahlukeneyo zezicelo, ezifana nezihluzi, ii-catalysts, kunye nokutshintsha ubushushu. I-HPMC sisibophelelo esifanelekileyo kwiseramikhi yenqatha lobusi ngenxa yamandla ayo okubopha okuphezulu, ixabiso eliphantsi, kunye nokusebenziseka ngokulula.

I-HPMC yipolymer enyibilikayo emanzini eyenziwe ngeemolekyuli zeselulosi eziye zalungiswa ngamaqela e-hydroxypropyl. Oku kuguqulwa kwenza i-polymer inyibilike ngakumbi emanzini kwaye inika amandla aphezulu okubopha kunezinye iipolymers ezisekelwe kwi-cellulose. I-HPMC nayo izinzile kakhulu kwaye inokumelana namaqondo obushushu aphezulu, iyenza ibe sisibophelelo esifanelekileyo kwiiseramikhi zenqatha lobusi.

Xa isetyenziswa njengesibophelelo kwiiseramikhi zenqatha lobusi, i-HPMC ixutywa nezinye izithako, ezifana nodongwe, i-silica, kunye ne-alumina, ukwenza i-slurry. Olu daka lugalelwa kwi-mold kwaye luvunyelwe ukuba lome. Njengoko i-slurry isoma, i-HPMC ibophelela ezinye izithako kunye, zenze i-ceramic yobusi eyomeleleyo kunye nehlala ixesha elide.

HPMC ikwasetyenziswa kwezinye izicelo, ezifana nokuncamathelisa, ukutyabeka, kunye neemveliso zephepha. Kwezi zicelo, i-HPMC ibonelela ngeqhina eliqinileyo phakathi kwemiphezulu emibini, iyenza ibe lolona khetho lufanelekileyo kwiimveliso ezahlukeneyo.

I-HPMC sisibophelelo esisebenza ngeendlela ezininzi kwaye esinexabiso elisebenzayo kwiiseramikhi zenqatha lobusi. Kulula ukuyisebenzisa, inamandla amakhulu okubopha, kwaye izinzile kumaqondo obushushu aphezulu. HPMC kwakhona non-ityhefu kunye nokusingqongileyo friendly, iyenza ibe ukhetho olufanelekileyo ezahlukeneyo izicelo.
