1. sịntetik Calcium Silicate – Thermal mkpuchi ihe na-acha ọcha
Silicate calcium sịntetị dị n'ụdị abụọ: ihe owuwu porous/spherical na seramiiki-fiber-dị ka fibrous owuwu. N'agbanyeghị ihe mejupụtara na morphological iche, ha abụọ na-eje ozi dị ka ndị magburu onwe elu-okpomọkụ iguzogide thermal ikpuchi ọcha fillers.
sịntetik calcium silicate eriri bụ ihe na gburugburu ebe obibi enyi na enyi naihe mkpuchi okpomọkụ dị mmana oke okpomọkụ na-eguzogide ruo 1200-1260 ° C. Ngwakọta calcium silicate fiber synthetic nke a na-edozi nke ọma nwere ike ịrụ ọrụ dị ka ihe na-eme ka eriri na-eme ka ọ dịkwuo elu maka mkpuchi okpomọkụ.
Silicate nke sịntetik ma ọ bụ sppherical calcium silicate, ka ọ dị ugbu a, na-egosipụta ịdị ọcha dị elu, ịdị mfe nke ntinye, usoro nanoporous bara ụba, ụkpụrụ nnabata mmanụ dị elu (ruo 400 ma ọ bụ karịa), na nnwere onwe pụọ na bọọlụ slag ma ọ bụ nnukwu ahụ. O gosiputara ngwa n'ime mkpuchi na-eguzogide okpomọkụ dị elu na ogwe ọkụ ọkụ, na-egosi na ọ ga-ekwe omume maka ntinye n'ime ihe ndị na-eguzogide ablation seramiiki iji nye mkpuchi okpomọkụ dị elu.
Ngwa ndị ọzọ gụnyere: ihe mgbakwunye mmiri ntụ ntụ, mkpuchi ntụ ntụ na-ekpo ọkụ na-ekpo ọkụ, ndị na-ebu ihe na-esi ísì ụtọ, ihe mgbochi mmiri, ihe mgbochi breeki, rọba silicone dị ala na mmanụ silicone na-emebi onwe ya, ihe mpempe akwụkwọ, wdg.
2. Magnesium Aluminom Silicate nke nwere porous- Mkpuchi ọkụ & Nguzogide oke okpomọkụ
Ngwunye silicate a na-achọ calcination okpomọkụ na refractoriness ruo 1200 Celsius. Ihe mejupụtara ya bụ magnesium aluminom silicate, ọ na-egosipụta ihe owuwu porous nwere akwa akwa nke na-enye ike njikọ dị elu, nguzogide mmiri dị mma, ogologo oge refractory, yana ọnụ ahịa dị elu.
Ọrụ ya bụ isi gụnyere mkpuchi okpomọkụ dị elu, mbelata njupụta, nkwụghachi azụ na-emewanyewanye, yana nkwụsi ike nke ablation ka mma na mkpuchi okpomọkụ maka ọkwa carbon na casings. Ngwa gụnyere ihe mkpuchi seramiiki, mkpuchi mkpuchi ọkụ adịchaghị, ihe mkpuchi mkpuchi, yana ihe mkpuchi ọkụ na-eguzogide ablation.
3. Ceramic Microspheres - Nguzogide okpomọkụ dị elu, mkpuchi okpomọkụ, ike mgbagwoju anya.
Ihe ịrụ ụka adịghị ya na microspheres iko oghere bụ ezigbo ihe mkpuchi ọkụ, mana nguzogide okpomọkụ ezughị oke. Ebe ha na-adị nro na-adịkarị site na 650-800C, yana okpomọkụ na-agbaze na 1200-1300C. Nke a na-egbochi ngwa ha na ọnọdụ mkpuchi mkpuchi okpomọkụ dị ala. N'okpuru ọnọdụ okpomọkụ dị elu dị ka ceramicization na nkwụsị nke ablation, ha na-aghọ adịghị arụ ọrụ.
Microspheres seramiiki oghere anyị na-edozi okwu a. Ihe mejupụtara aluminosilicate bụ isi, ha na-enye nguzogide okpomọkụ dị elu, ihe mkpuchi ọkụ pụtara ìhè, nkwụghachi dị elu, na nguzogide mgbaji dị elu. Ngwa gụnyere ihe mgbakwunye seramiiki silicone, ihe mkpuchi mkpuchi, ihe mgbakwunye okpomọkụ maka resin organic, yana mgbakwunye rọba na-eguzogide okpomọkụ. Akụkụ ndị dị mkpa gụnyere ikuku ikuku, nyocha miri emi, ihe ndị mejupụtara, mkpuchi, mkpuchi mkpuchi, ụlọ ọrụ mmanụ ala, na ihe mkpuchi.
Nke a bụ micropowder oghere na-eguzogide okpomọkụ nke dị oke mfe itinye (n'adịghị ka microspheres iko oghere, nke chọrọ tupu mgbasa ma ọ bụ mgbanwe maka mgbakwunye kwesịrị ekwesị) ma na-egosipụta nguzogide mgbape dị mma. Ihe dị iche iche ya bụ na ọ bụ ihe na-emepe emepe nke na-adịghị ese n'elu mmiri, na-eme ka ọ dị mfe ịgbatị ma dozie ya.
Ọzọkwa, a nkenke kwuruairgel ntụ ntụ- ihe mkpuchi silica porous sịntetik. A na-amata Airgel dị ka ezigbo ihe mkpuchi ọkụ, dị na ụdị hydrophobic/hydrophilic. Nke a na-enye ohere nhọrọ nke usoro ọgwụgwọ kwesịrị ekwesị dabere na resin substrates, na-eleba anya n'ihe ịma aka nke airgel ntụ ntụ nke mgbasa nke ultra-fefe na mgbasawanye ya. Tapawa airgel dabere na mmiri dịkwa maka itinye aka na sistemu mmiri.
Ihe dị iche iche na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ nke airgel ntụ ntụ na-eme ka ngwa ya dị na: - Rubber na plastic additive carriers - Thermal mkpuchi ihe maka batrị ọhụrụ ume - Ụlọ ihe mkpuchi mkpuchi ụlọ - Ihe mkpuchi ihe mkpuchi ihe mkpuchi - Ụlọ ihe mkpuchi ụlọ - mkpuchi mkpuchi ọkụ na-ekpuchi ọkụ - mkpuchi mkpuchi ọkụ.
