Uluhlu lokumelana nobushushu besiqhelo

Ixesha lokukhupha: 2025-12-25

Isabelo:

Uluhlu lokumelana nobushushu besiqhelonano airgel felinokusebenza okugqwesileyo kwe-thermal insulation. Impembelelo yokugquma kwe-thermal ye-nano airgel ivakale ingaphezulu lee kuleyo yemathiriyeli yesiqhelo yokugquma ubushushu. Ngeengenelo ezizodwa zesakhiwo se-nano porous, iye yaba "yi-ace yokufaka ubushushu" phantsi kweemeko ezinzima ezifana nobushushu obuphezulu beshishini kunye nokubanda okukhulu. Iziphumo ezithile zokusebenza zingandiswa ukusuka kwimilinganiselo engundoqo elandelayo:
i-silica aerogel, engaphezulu kwe-90% ye-nano pores ngaphakathi, kwaye ubungakanani bepore buncinci kakhulu kunendlela yamahhala yeemolekyuli zomoya, ezinokuthi zikhulise ukuchasana nokuqhuba ubushushu, i-convection kunye nemitha.

4. I-Anti thermal shock + lightweight bhetyebhetye, ngakumbi ukukhathazeka ukwakhiwa kunye nokugcinwa

nano airgel wazivaNano airgel waziva? I-Nano airgel ivakale "yeyona ndlela iphezulu yokusebenza kunye nebenchmark yokonga amandla" yokugquma kwimizi-mveliso. Iimveliso ze
Kwiqondo lokushisa, i-thermal conductivity yayo iphantsi kwe-0.018-0.025W / (m · K), nto leyo isiqingatha kuphela soboya belitye (0.04-0.05W / (m · K)) kunye ne-60% -70% ye-cotton fiber ye-ceramic (0.03-0.06W / (m · K)). Ngaphantsi kwempembelelo efanayo yokufakelwa kwe-thermal, ubukhulu bokubeka i-airgel ivakalelwa kuphela yi-1/3 - 1/2 yezinto zemveli, ezinokugcina kakhulu indawo yokufakela izixhobo.

I-nano airgel ivakale, isiphumo se-nano airgel ivakale, isiphumo sokufakelwa kwe-thermal ye-nano airgel ivakale

Yintoni i-thermal insulation effect yeNano airgel wazivaigubungela -200 ℃ ~ 650 ℃, kwaye imodeli eguquliweyo yokumelana nobushushu inokufikelela ngaphezulu kwe-1000 ℃. Ayinakusetyenziselwa ukugquma okubandayo kwezixhobo ze-cryogenic ezifana nenitrogen engamanzi kunye neoksijini engamanzi, kodwa ikwahlangabezana neemfuno zokugquma kwe-thermal kwizibiyeli zesikhululo samandla, ii-kilns ze-metallurgical, kunye nemibhobho yobushushu obuphezulu.
Okubaluleke ngakumbi, kwiindawo ezahlukeneyo zokushisa okugqithisileyo, i-thermal conductivity yayo ayiguquguquki kakhulu kwaye igcina ukusebenza kwe-insulation ezinzileyo, iphezulu kakhulu kunoboya belitye obuxhomekeke ekungaphumeleli komswakama kumaqondo aphantsi kunye ne-calcium silicate ngokunyuka ngokukhawuleza kwe-thermal conductivity kumaqondo aphezulu okushisa.

Yintoni i-thermal insulation effect ye-nano airgel ivakalelwe?

Umgangatho ophezulu we-nano airgel waziva uphathwe nge-hydrophobicity, kwaye izinga le-hydrophobicity linokufikelela ngaphezu kwe-98%. Nokuba ikwindawo efumileyo kunye nokufuma okuphezulu ixesha elide, ayizukufunxa ukufuma.
Nangona kunjalo, izixhobo zokugquma zemveli ezifana noboya belitye kunye noboya beglasi ziya kuba namava okwehla okungaphezulu kwama-50% ekusebenzeni kokugquma emva kokufunxa amanzi, okunokuthi kukhokhelele ekudlekeni kwezixhobo; Ijeli yomoya ezivayo inokunqanda le ngxaki, ngakumbi ilungele iimeko ezimanzi ezifana nobunjineli bekhemikhali, ubunjineli baselwandle kunye nobunjineli obuphantsi komhlaba.

5. Ikhuselekile kokusingqongileyo kunye nedangatye-retardant, kunye nemigangatho yokusebenza yokhuseleko

Ubunzima bomthamo we-airgel evakalayo yi-180 - 300kg/m ³ kuphela. Ithambile kwaye ibhetyebhetye, kwaye inokusongwa ngokuthe ngqo kumphezulu wezakhiwo ezintsonkothileyo ezinjengemibhobho emile okwezodwa, iivalvu, kunye neeflange zezixhobo. Inokunqunyulwa kwaye ifakwe ngaphandle kwefom enzima, iphucula kakhulu ukusebenza kakuhle kofakelo.
Ngexesha elifanayo, i-coefficient yayo yokwandiswa kwe-thermal iphantsi kakhulu, ikwazi ukujamelana nokuguquguquka kweqondo lokushisa rhoqo, kwaye ayiyi kuqhekeka okanye iwele ngenxa yokwandiswa kwe-thermal kunye nokucutha njengama-castables anzima. Ubomi bayo benkonzo ngamaxesha angama-2-3 ubude kunezixhobo zendabuko, ukunciphisa iindleko zokugcinwa kwinqanaba elilandelayo.

3. I-Hydrophobic kunye nobungqina bokufuma, ayiboli kwiindawo ezifumileyo

Inxalenye ephambili ye-nano airgel ivakale yi-silicon dioxide ye-inorganic, engenayo i-asbestos, i-formaldehyde kunye nezinye izinto ezinobungozi. Ukusebenza kwayo kokutsha kuye kwafikelela kwiKlasi A engatshiyo. Ayiyi kukhulula iigesi ezinetyhefu kumaqondo obushushu aphezulu. Ihlangabezana neemfuno zokhuseleko lokusingqongileyo kwimizi-mveliso kunye nokhuseleko lomlilo, kwaye ifanelekile ngokukhethekileyo kwiikhemikhali, amandla ombane kunye neendawo zokwakha ezineemfuno eziqinileyo zokukhusela nokukhuseleka kokusingqongileyo.

IRosewool Insulation Refractory Co.,Ltd 2. Uluhlu olubanzi lweqondo lokushisa oluzinzile, olukwazi ukusebenza phantsi kweemeko zombini eziphezulu kunye neziphantsiIcandelo eliphambili leube ne-ultra-low heat conduction ye-<0.018W/(m ・ K), ukuzinza koluhlu olubanzi lobushushu be -200 ℃ ~ 1000 ℃, 99.5% + hydrophobic kunye nokuguquguquka okulula, kwaye kunokonga amandla kakhulu phantsi kweemeko zokusebenza ezinzima ezifana nokushisa okuphezulu /kubanda okunzulu / ukufuma. Ukudibanisa unikezelo lwendawo kunye neenkonzo zobugcisa ezilungiselelweyo, lolona khetho lulungileyo lokuphucula ukugqunywa kwamashishini.
