Kule minyaka mibini idlulileyo, iqhutywa kukuvela kwetekhnoloji yezixhobo zokukhusela ezibalekayo kwiibhetri zamandla amatsha, abathengi baye bafune ukongezwa kokusebenza kobushushu ecaleni kwe-ceramic-like ablation resistance-ipropathi ephambili yokumelana nefuthe lomlilo.
Umzekelo, ezinye izicelo zifuna ubushushu becala elingaphambili lomlilo we-1200°C ngelixa ugcina amaqondo obushushu asemva ngasemva angaphantsi kwe-300°C. Kwimathiriyeli ye-aerospace, icala elingaphambili le-acetylene ablation kwi-3000°C lifuna amaqondo obushushu asemva kwe-150°C. Owona mceli mngeni kukuphakama kwemfuno yokusebenza koxinzelelo kwi-ceramicized silicone foam, efuna zombini iseti yoxinzelelo oluphantsi kunye nogcino olugqwesileyo lobushushu kumaqondo obushushu aphezulu. Ezi zixhobo ngokudibeneyo zibonisa iimfuno ezintsha zokufakelwa kwe-thermal kwitekhnoloji ye-ceramicization.
Iimfuno zokusebenza ezikhethekileyo (ngokubhekiselele kuphela):
Fudumeza isampuli kwiqonga lokufudumeza njengoko kuboniswe ngezantsi. Gcina indawo eshushu kwi-600 ± 25 °C imizuzu eyi-10. Faka uxinzelelo lwe-0.8±0.05 MPa kwiqondo lokushisa lokuvavanya, uqinisekise ukuba ubushushu bomhlaba obungasemva buhlala bungaphantsi kwe-200 ° C.
Namhlanje, sishwankathela la manqaku ukuze wenze ireferensi yakho.
1. I-Synthetic Calcium Silicate - I-Thermal Insulation White Filler
I-Synthetic calcium silicate ikhona ngeendlela ezimbini: izakhiwo ze-porous / spherical kunye ne-ceramic-fiber-like fibrous structures. Ngaphandle kokwahluka kokwakheka kunye ne-morphological, zombini zisebenza njengezona zibalaseleyo kubushushu obuphezulu obuxhathisayo kwi-thermal insulation fillers ezimhlophe.
I-Synthetic calcium silicate fiber yinto ehambelana nokusingqongileyo kwayeizinto ezikhuselekileyo zokugquma i-thermalngokumelana nobushushu obuphezulu ukuya kuthi ga kwi-1200-1260°C. Ukwenziwa ngokukodwa kokwenziwa kwe-calcium silicate fiber powder kunokusebenza njengefiber-reinforced material for high-temperature insulation.
I-synthetic porous or spherical calcium silicate, okwangoku, ibonisa ubumhlophe obuphezulu, ukukhululeka kokufakwa, isakhiwo esicebileyo se-nanoporous, i-ultra-high high-absorption values (ukuya kwi-400 okanye ngaphezulu), kunye nenkululeko kwiibhola ze-slag okanye iinqununu ezinkulu. Inezicelo eziqinisekisiweyo kwi-high-temperature resistant insulation kunye neepaneli zomlilo, ebonisa ukuba nokwenzeka kokufakwa kwi-ceramicized ablation-resistant materials ukubonelela ngobushushu obuphezulu.
Ezinye izicelo zibandakanya: izongezo zolwelo oluyimpuphu, ubushushu obuphezulu bokugquma umgubo, abathwali be-perfume adsorbent, i-anti-drip agents, izinto zokukhuhlana kwe-brake pad, irabha ye-silicone enoxinzelelo oluphantsi kunye ne-oyile ye-silicone ezibolayo, izigcwalisi zephepha, njl.
2. Ilayered Porous Magnesium Aluminium Silicate-I-Thermal Insulation & High-Temperature Resistance
Le minerali ye-silicate idinga ukubalwa kobushushu obuphezulu kunye ne-refractoriness ukuya kwi-1200 ° C. Ngokuyintloko yenziwe nge-magnesium aluminium silicate, inesakhiwo esityebileyo esine-porous esinikezela amandla okubopha okuphezulu, ukumelana namanzi okugqwesileyo, ixesha elide lokuchasa, kunye nokusebenza kakuhle kweendleko.
Imisebenzi yayo ephambili ibandakanya ukugquma kobushushu obuphezulu, ukuncitshiswa koxinaniso, ukunyanzeliswa kwe-refractoriness, kunye nokuphucula ukuxhathisa ukukhutshwa kwe-ablation kunye ne-thermal insulation ye-carbon layers kunye ne-casings. Usetyenziso lubandakanya imathiriyeli yokugquma i-ceramicized, i-premium yokugquma i-fireproof, imathiriyeli yokugquma i-refractory, kunye ne-ablation-resistant in thermal insulation materials.
3. IiMikrosphere zeCeramic-Ukumelana nobushushu obuphezulu, i-Thermal Insulation, amandla acinezelayo
I-Microspheres yeglasi eHollow ngokungathandabuzekiyo igqwesileyo kwizinto zokufakelwa kwe-thermal, kodwa ukumelana nobushushu babo akwanelanga. Amanqaku abo okuthambisa ngokubanzi aqala kwi-650-800 ° C, kunye namaqondo okunyibilika kwi-1200-1300 ° C. Oku kunciphisa ukusetyenziswa kwabo kwiimeko eziphantsi zobushushu be-thermal insulation. Phantsi kweemeko zobushushu obuphezulu obufana ne-ceramicization kunye nokumelana nokukhupha amanzi, ziye zingasebenzi.
Iimicrosphere zethu zeceramic ezingenanto ziwusombulula lo mba. Ngokuyintloko yenziwe nge-aluminosilicate, inikezela ukumelana nobushushu obuphezulu, ukugqunywa kwe-thermal okugqwesileyo, ukuchasana okuphezulu, kunye nokumelana nokwaphuka okuphezulu. Izicelo zibandakanya izongezo ze-silicone ceramic, izinto zokufakelwa kwe-refractory, i-additives ephezulu yokushisa ye-organic resins, kunye ne-high-temperature resistant rubber additives. Amacandelo aphambili abandakanya i-aerospace, uphononongo olunzulu lolwandle, imathiriyeli edibeneyo, iingubo, ukugquma kwe-refractory, ishishini lepetroleum, kunye nemathiriyeli yokugquma.
Le yimicropowder engqukuva ekwazi ukumelana nobushushu ekulula kakhulu ukuyidibanisa (ngokungafaniyo neglasi yemicrospheres enomgongxo, efuna ukusasazwa kwangaphambili okanye ukuguqulwa kokudibanisa okufanelekileyo) kwaye ibonisa ukuxhathisa okugqwesileyo kokuqhekeka. Isici sayo esahlulayo kukuba yinto evulekileyo evulekileyo engadada emanzini, okwenza kube lula ukujiya kunye nokuhlalisa.
Ukongeza, ukukhankanya ngokufutshanei-airgel powder-Imathiriyeli yokugquma i-silica eyenziweyo. I-Airgel yamkelwa ngokubanzi njengeyona insulator yobushushu egqwesileyo, efumaneka kwi-hydrophobic/hydrophilic variants. Oku kuvumela ukhetho lweendlela ezifanelekileyo zonyango ezisekelwe kwi-resin substrates, ukujongana nemingeni ye-airgel powder ye-ultra-lightweight dispersibility kunye nokuphucula i-dispersibility yayo. I-Airgel pastes esekwe emanzini iyafumaneka ukuze ifakwe lula kwiinkqubo ezinamanzi.
Iipropati ezikhethekileyo zokugquma kwe-thermal ze-airgel powder zivumela ukusetyenziswa kwayo kwi-: - I-Rubber kunye ne-plastic additive carriers - Izinto zokugquma i-Thermal zokugquma iibhetri zamandla amatsha - I-insulation insulation yezakhiwo - I-Thermal insulation textile fibers - Iipaneli zokugquma i-insulation - I-fireproof insulation insulation - I-adhesives e-thermal insulation.
