Pazaka ziwiri zapitazi, motsogozedwa ndi kusinthika kwaukadaulo kwa zida zodzitetezera zomwe zikutha mphamvu zamabatire amagetsi atsopano, makasitomala akuchulukirachulukira kufuna kulimbikitsidwa kwamatekinoloje otenthetsera pamodzi ndi ceramic-ngati ablation resistance-chinthu chofunikira kwambiri kuti zisawonongeke.
Mwachitsanzo, ntchito zina zimafuna kutentha kwa mbali yakutsogolo kwa 1200 ° C ndikusunga kutentha chakumbuyo pansi pa 300 ° C. M'zinthu zakuthambo, kutsogolo kwa moto wa acetylene pa 3000 ° C kumafuna kutentha kwa kumbuyo kwa 150 ° C. Chovuta kwambiri ndi kufunikira kowonjezereka kwa ntchito yoponderezedwa mu thovu la silicone la ceramic, lomwe limafunikira kuyika kwapang'onopang'ono komanso kusungidwa kwabwino kwa kutentha kwa kutentha kwambiri. Zida izi pamodzi zimapereka zofunikira zatsopano zotenthetsera zaukadaulo wa ceramicization.
Zofunikira pakugwirira ntchito (zongotanthauza zokha):
Kutenthetsa chitsanzo pa nsanja yotentha monga momwe zilili pansipa. Sungani malo otentha pa 600 ± 25 °C kwa mphindi 10. Ikani kupsinjika kwa 0.8 ± 0.05 MPa pa kutentha kwa mayeso, kuonetsetsa kuti kutentha kwapambuyo kumakhala pansi pa 200 ° C.
Lero, tikuwomba mwachidule mfundo izi kuti mugwiritse ntchito.
1. Synthetic Calcium Silicate - Thermal Insulation White Filler
Synthetic calcium silicate ilipo m'njira ziwiri: porous/spherical structures ndi ceramic-fiber-ngati fibrous structures. Ngakhale pali kusiyana kophatikizana ndi morphological, zonse zimagwira ntchito ngati zotchingira zoyera zoteteza kutentha kwambiri.
Synthetic calcium silicate CHIKWANGWANI ndi chilengedwe wochezeka komansootetezeka matenthedwe kutchinjiriza zakuthupindi kukana kutentha kwambiri mpaka 1200-1260 ° C. Mwapadera kukonzedwa kashiamu silicate CHIKWANGWANI ufa akhoza kukhala CHIKWANGWANI-zinalimbitsa zinthu kutchinjiriza mkulu kutentha.
Pakalipano, porous porous kapena spherical calcium silicate, imakhala ndi zoyera kwambiri, zosavuta kuphatikizika, mawonekedwe olemera a nanoporous, mayamwidwe apamwamba kwambiri amafuta (mpaka 400 kapena kupitilira apo), komanso kumasuka ku mipira ya slag kapena tinthu tating'onoting'ono. Zatsimikiziridwa kuti zimagwiritsidwa ntchito muzitsulo zosagwira kutentha kwambiri ndi mapanelo osayaka moto, kusonyeza kuthekera kwa kuphatikizidwa mu zipangizo za ceramicized ablation-resistant kuti zipereke kutentha kwapamwamba.
Ntchito zina ndi monga: zowonjezera zamadzimadzi zaufa, zokutira za ufa wotentha kwambiri, zonyamulira zonunkhiritsa, anti-drip agents, zida zama brake pad, mphira wocheperako wa silicone ndi mafuta odziwola okha, zodzaza mapepala, ndi zina zambiri.
2. Zosanjikiza Porous Magnesium Aluminium Silicate- Thermal Insulation & High-Temperature Resistance
Mchere uwu wa silicate umafunika kuwerengera kutentha kwambiri ndi refractoriness mpaka 1200 ° C. Wopangidwa makamaka ndi magnesium aluminium silicate, imakhala ndi mawonekedwe owoneka bwino a porous omwe amapereka mphamvu zomangirira kwambiri, kukana kwamadzi bwino, kutalika kwanthawi yayitali, komanso kukwera mtengo kwake.
Ntchito zake zazikuluzikulu zimaphatikizira kutchinjiriza kutentha kwambiri, kuchepetsa kachulukidwe, kulimbikitsa kukana, komanso kukana kutulutsa mpweya wabwino komanso kutchinjiriza kwamafuta pamagawo a kaboni ndi ma casings. Mapulogalamuwa amaphatikizapo zotchinjiriza za ceramicized, zokutira zotchingira moto, zotchingira zotchinga, ndi zida zotchinjiriza zosagwira ablation.
3. Ceramic Microspheres - Kukaniza Kutentha Kwambiri, Kutentha kwa Matenthedwe, Mphamvu Zoponderezedwa
Magalasi opanda magalasi ang'onoang'ono mosakayikira ndi zida zabwino kwambiri zotetezera kutentha, koma kukana kwawo kutentha sikukwanira. Kufewetsa kwawo nthawi zambiri kumachokera ku 650-800 ° C, ndi kutentha kwa 1200-1300 ° C. Izi zimachepetsa ntchito yawo ku zochitika zotsika kutentha kwa kutentha. Pansi pa kutentha kwambiri monga ceramicization ndi ablation resistance, amakhala osagwira ntchito.
Ma microspheres athu opanda kanthu a ceramic amathetsa nkhaniyi. Makamaka opangidwa ndi aluminosilicate, amapereka kukana kutentha kwambiri, kutsekemera kwapadera kwamafuta, kukana kwambiri, komanso kukana kwapang'onopang'ono. Mapulogalamuwa akuphatikiza zowonjezera za silicone ceramic, zida zotchingira zotchinga, zowonjezera kutentha kwambiri kwa utomoni wa organic, ndi zowonjezera zosagwirizana ndi mphira. Magawo ofunikira amaphatikiza zakuthambo, kufufuza m'nyanja yakuya, zida zophatikizika, zokutira, zotchingira zotchingira, mafakitale amafuta, ndi zida zotsekera.
Ichi ndi chozungulira chozungulira chosatentha chomwe chimakhala chosavuta kuphatikizira (mosiyana ndi magalasi opanda kanthu, omwe amafunikira kubalalitsidwa kapena kusinthidwa kuti awonjezedwe moyenera) ndipo amawonetsa kukana kwabwino kwambiri. Chosiyanitsa chake ndi chakuti ndi chinthu chotseguka pamwamba chomwe sichiyandama pamadzi, chomwe chimapangitsa kuti zikhale zosavuta kulimbitsa ndi kukhazikika.
Komanso, kutchula mwachidule zaairgel powder-chopangidwa ndi porous silika insulation material. Airgel imadziwika kuti ndi insulator yabwino kwambiri, yomwe imapezeka mumitundu ya hydrophobic/hydrophilic. Izi zimalola kusankha njira zoyenera zochizira kutengera magawo a utomoni, kuthana ndi zovuta za airgel powder pakubalalika kopepuka kwambiri ndikuwongolera dispersibility. Zopaka za airgel zochokera m'madzi zimapezekanso kuti zikhale zosavuta kuziyika m'makina amadzi.
Mapangidwe apadera a porous matenthedwe amtundu wa airgel powder amathandiza kuti agwiritsidwe ntchito mu: - Zonyamulira za Rubber ndi pulasitiki zowonjezera - Zida zotetezera kutentha kwa mabatire atsopano amphamvu - Zopaka zomangira zomanga - Nsalu za nsalu zotentha - Zomangamanga zomanga - Zopaka zotetezera kutentha kwa moto - Zomatira zotsekemera zotentha.
