Ka ọ dị ugbu a, a na-ejikarị seramiki cordierite mmanụ aṅụ dị ka ihe na-ebu ihe na-eme ka ike iyuzucha ọcha.Ụlọ ọrụ American Corning bụ nke mbụ kwadebere ceramics Cordierite (ee, Corning gorilla glass, nke na-enye enyo azụ azụ maka ekwentị mkpanaka Apple) site na ịkpụzi extrusion na 1960.

N'ihi na extrusion ịkpụzi nke cordierite ebuanu seramiiki, e nwere ụzọ abụọ usoro nhọrọ: raw nri na clinker, na isi ihe dị iche n'etiti abụọ usoro bụ ma e nwere tupu njikọ njikọ cordierite ntụ ntụ.Na usoro clinker, a na-emepụta ntụ ntụ cordierite na mbụ, wee wepụ ya;Na usoro nri raw, a na-emepụta cordierite site na extrusion na sintering.Onyonyo 4 na-egosi usoro mmepụta abụọ nke cordierite mmanụ aṅụ ceramik.

Na mgbakwunye na usoro mmepụta ihe dị iche iche, ihe ndị e ji eme ihe maka ceramics cordierite honeycomb sitere n'ọtụtụ ebe dị iche iche, na ndị isi na-emepụta dị iche iche.Dịka e gosiri na eserese 5, anyị nwere ike ịhụ ụdị nhọrọ akụrụngwa dị iche iche.

N'ihi nnukwu arụmọrụ chọrọ nke ceramics ụgbọ ala ebu (ọtụtụ isi ihe edepụtara n'elu), nkọwapụta nke akụrụngwa siri ike.Dị ka ihe atụ, ọ na-kpọmkwem na median urughuru size nke cordierite ntụ ntụ bụ n'ime 10-50um, nkezi urughuru size nke talc isi iyi bụ dịkarịa ala 8um, nkezi median urughuru size nke alumina isi iyi abụghị ihe karịrị 5um, na nkezi median. nha nke kaolin na ngwakọta kaolin calcined abụghị ihe karịrị 6um.

Na mgbakwunye na nha nha, n'ime afọ ndị na-adịbeghị anya, a chọpụtakwara na morphology nke cordierite ntụ ntụ nwere mmetụta dị ukwuu na ngwaahịa ikpeazụ.N'ihi na mpempe akwụkwọ udi nwere ike anisotropy n'oge extrusion ịkpụzi (nke a ka ewepụtara na aga isiokwu na extrusion ịkpụzi. Ọ bụ ihe ezi uche dị na anyị chọrọ izere anisotropy, ma gịnị mere anyị na-apụghị iji ya?).Na patent US nke aha ya bụ "anisotropiccordierite molonlish", Lachman im na ndị ọzọ na-eji mmịfe na ntụgharị nke kaolin dị nro mee ihe n'ụzọ zuru ezu iji mee ka ọ na-aga n'ihu n'ụgbọelu.Mgbe agbachara, enwere ike ime nhazi nhazi nke ọka cordierite n'ụdị mmanụ aṅụ.Cordierite gbakwasara agbawa nwere anisotropy na mgbasawanye thermal, yabụ na ọ nwere ike iru ọnụọgụ mgbasawanye thermal dị ala (nchịkọta mgbasawanye thermal ikpeazụ bụ naanị 0.55) × 10-6 / ℃).

Ka ọ dị ugbu a, teknụzụ bụ isi maka imepụta ceramics cordierite honeycomb dị elu ka na-ejikwa ụlọ ọrụ Corning nke United States na NGK nke Japan nọchitere anya ya.Agbanyeghị, site na mgbasawanye na-aga n'ihu nke ahịa ihe na-ebu ụgbọ ala yana mmụba na-aga n'ihu nke ike nyocha ụlọ, nnọchi ụlọ maka mbubata na-aghọ ihe dị adị.

N'ikpeazụ, ọ bara uru ịkọwa na nso nso a, Shanghai kwupụtara na a ga-emejuputa ụkpụrụ "mba isii" site na July 1 nke afọ a.Tụnyere ụkpụrụ ise nke mba, ụkpụrụ isii nke mba ahụ siri ike n'ozuzu ya, ọkachasị gụnyere:

(1) Mkpọpụta carbon monoxide sitere na ụgbọ ala mmanụ ụgbọala belatara 50%

(2) Oke ikuku nke mkpokọta hydrocarbons na mkpokọta hydrocarbons na-abụghị methane belatara site na 50% (23% site na mba IV ruo obodo V)

(3) Eji 42% mechie oke ikuku NOx (webiri 28% site na obodo IV ruo obodo V)

Site na uto ngwa ngwa nke ahịa ụgbọ ala ụlọ yana mmụba n'ihu nke ụkpụrụ ikuku, enwere nnukwu ahịa ahịa maka seramiki cordierite mmanụ aṅụ maka ịdị ọcha gas.Ekwenyere na ụlọ cordierite mmanụ aṅụ ceramics maka ụgbọ ala nwere ike inwe ọganihu ka mma n'ọdịnihu.
