Isingeniso kubuchwepheshe be-microporous ceramics

I-Fountyl Technologies PTE Ltd ingakha i-chuck evalekile ye-ceramic esezingeni eliphakeme, i-porous ceramics, i-Ceramic chuck, izindwangu ze-adsorbent nama-silicon wafers, ama-wafers, amawafa e-ceramic, izikrini eziguqukayo, izikrini zengilazi, amabhodi wesekethe nezinye izinto ezingezona ezensimbi.

Uhlolojikelele lwe-Porous Ceramics

Uma kuziwa kuma-ceramics amancane, kufanele sikhulume nge-porous ceramics kuqala.

I-Porous Ceramics iwuhlobo olusha lwe-ceramic material, eyaziwa nangokuthi i-pore functional ceramics, emva kokubalwa kokushisa okuphezulu nokucwengisiswa, ngoba inqubo yokudubula izokhiqiza isakhiwo esinezimbobo kakhulu, ngakho-ke yaziwa nangokuthi i-ceramics e-porous, inombolo enkulu izinto ze-ceramic ezinama-pores axhumene noma avaliwe emzimbeni.

Ukuhlukaniswa kwama-ceramics anezimbotshana

I-ceramics enezimbotshana ingahlukaniswa kusukela kubukhulu, ukwakheka kwesigaba kanye nesakhiwo se-pore (usayizi we-pore, i-morphology kanye nokuxhumana).

Ngokusho kobukhulu bembotshana, ihlukaniswe yaba: izimbotshana ze-pore eziqinile (usayizi wembotshana> 500μm), izimbotshana ezinkulu ze-pore (usayizi wembotshana 100 ~ 500μm), i-pores ephakathi nendawo (usayizi wembotshana 10 ~ 100μm), i-porosity porous ceramics encane ( usayizi wembotshana 1~50μm), i-pore porous ceramics (usayizi wembotshana 0.1~1μm) kanye ne-micro-porosity porous ceramics. ngokusho kwesakhiwo se-pore, i-ceramics enezimbotshana ingahlukaniswa ibe yi-ceramics enezimbotshana ezifanayo kanye nezitsha zobumba ezingajwayelekile.

Incazelo ye-microporous ceramics

I-Microporous ceramics iyisakhiwo se-pore esifana ne-micro-porosity porous ceramics, iwuhlobo olusha lwe-ceramic material, iphinde ibe i-ceramic yesakhiwo esisebenzayo, njengoba igama liphakamisa, ingaphakathi kwe-ceramic noma indawo equkethe inani elikhulu lokuvula noma lokuvala i-micro- izimbotshana zomzimba we-ceramic, ama-micropores we-ceramics encane kakhulu, ukuvuleka kwawo ngokuvamile kuba yizinga le-micron noma le-sub-micron, ngokuyisisekelo alibonakali ngeso lenyama. Kodwa-ke, izitsha zobumba ezincane ziyabonakala empilweni yansuku zonke, njengesihlungi se-ceramic esisetshenziswa kusihlanzi samanzi kanye nengqikithi ye-atomization kugwayi we-elekthronikhi.

Umlando we-microporous ceramics

Eqinisweni, ucwaningo lomhlaba wonke mayelana ne-microporous ceramics lwaqala ngawo-1940, futhi ngemva kokukhuthaza ngempumelelo ukusetshenziswa kwalo embonini yezobisi kanye nesiphuzo (iwayini, ubhiya, i-cider) embonini yaseFrance ekuqaleni kwawo-1980, yaqala ukusetshenziswa ekuhlanzeni indle kanye nokuphuza. ezinye izinkambu ezihambisanayo.

Ngo-2004, ivolumu yokuthengiswa kwemakethe ye-ceramics emhlabeni ingaphezu kwezigidigidi eziyi-10 zamadola aseMelika, ngenxa yokusetshenziswa ngempumelelo kwezitsha zobumba ezincane ekuhlukaniseni okunembayo kokuhlunga, ivolumu yokuthengiswa kwemakethe yayo ngezinga lokukhula lonyaka lama-35%.

Ukukhiqizwa kwezitsha zobumba ezincane

Izimiso nezindlela zezitsha zobumba ezinama-porous zihlanganisa ukupakishwa kwezinhlayiyana, i-ejenti yokwengeza izimbotshana, ukushisa okuphansi kokushisa okuphansi kanye nokucutshungulwa kwemishini. Ngokwendlela yokwakheka kwezimbotshana kanye nesakhiwo se-pore, izitsha zobumba ezinama-porous zingahlukaniswa zibe umzimba we-ceramic sintered granular (i-microporous ceramics), i-foam ceramics kanye ne-ceramics yezinyosi.

I-Microporous ceramics iwuhlobo olusha lwe-inorganic non-metallic filter material, i-microporous ceramics yakhiwa izinhlayiya ezihlanganisiwe, i-binder, i-pore yezingxenye ezi-3, isihlabathi se-quartz, i-corundum, i-alumina (Al2O3), i-silicon carbide (SiC), i-mullite (2Al2O3-3SiO2 ) kanye nezinhlayiya ze-ceramic njenge-aggregate, exutshwe nenani elithile le-binder, futhi ngemva kokushisa okuphezulu kokushisa nge-ejenti eyenza izimbotshana, izinhlayiya ezihlanganisiwe, ama-binders, ama-pore-forming agents kanye nezimo zazo zokubopha zinquma izici eziyinhloko zosayizi we-ceramic pore, i-porosity, ukuvumeleka. Ama-aggregates, njengama-adhesives, akhethwa ngokuvumelana nenhloso yokusetshenziswa komkhiqizo. Ngokuvamile kudingekile ukuthi isamba sibe namandla aphezulu, ukumelana nokushisa, ukumelana nokugqwala, eduze komumo webhola (okulula ukwakha ngaphansi kwezimo zokuhlunga), i-granulation elula phakathi kwebanga losayizi onikeziwe, kanye nokuhlobana okuhle nesibophezelo. Uma i-aggregate substrate kanye nosayizi wezinhlayiyana zifana, ezinye izimo ziyefana, usayizi wembotshana womkhiqizo, i-porosity, izinkomba zokungena komoya zingafinyelela inhloso efanelekile.
