Ububanzi bokumelana nezinga lokushisa kwezivamilenano airgel felinokusebenza okuhle kakhulu kwe-thermal insulation. Umthelela we-thermal insulation we-nano airgel ozwakalayo uphakeme kakhulu kunowezinto ezijwayelekile zokuvala ukushisa. Ngezinzuzo eziyingqayizivele zesakhiwo se-nano porous, isiphenduke "i-ace yokufaka ukushisa" ngaphansi kwezimo ezinzima ezifana nezinga lokushisa eliphezulu lezimboni kanye nokubanda okujulile. Imiphumela ethile yokusebenza inganwetshwa kusukela kubukhulu obulandelayo obuyingqikithi:
i-silica aerogel, enezimbotshana ze-nano ezingaphezu kuka-90% ngaphakathi, futhi ubukhulu bembotshana buncane kakhulu kunendlela yamahhala yama-athomu omoya, angakhulisa ukumelana nokushisa, ukuguquguquka kanye nemisebe.

4. I-Anti thermal shock+lightweight flexible, ukwakhiwa nokugcinwa kwamahhala kokukhathazeka okwengeziwe

I-nano airgel yazizwaI-Nano airgel yazizwa? I-Nano airgel izwakele "iwuphawu olusebenza kahle kakhulu nokonga amandla" lokugqunywa kwezimboni. Imikhiqizo ye
Emazingeni okushisa asekamelweni, ukuqhutshwa kwayo okushisayo kuphansi njengo-0.018-0.025W/(m · K), okuyingxenye kuphela yoboya bedwala (0.04-0.05W/(m · K)) kanye no-60% -70% we-ceramic fiber cotton (0.03-0.06W /(m · K)). Ngaphansi komphumela ofanayo wokufakwa kwe-thermal, ukushuba kokubeka kwe-airgel okuzwakalayo kungu-1/3 – 1/2 kuphela wezinto zendabuko, ezingasindisa kakhulu isikhala sokufakwa kwemishini.

I-nano airgel izwakele, umphumela we-nano airgel wezwa, umphumela wokushisa oshisayo we-nano airgel wezwa

Uyini umphumela we-thermal insulationI-Nano airgel yazizwaihlanganisa -200 ℃ ~ 650 ℃, futhi imodeli eguquliwe yokumelana nokushisa okuphezulu ingafinyelela ngaphezu kuka-1000 ℃. Ngeke isetshenziselwe kuphela ukufakwa okubandayo kwemishini ye-cryogenic efana ne-nitrogen ewuketshezi nomoya-mpilo owuketshezi, kodwa futhi ihlangabezana nezidingo zokufudumeza ezishisayo zamabhoyili esiteshi samandla, izikhonkwane ze-metallurgical, namapayipi ashisa kakhulu.
Okubaluleke nakakhulu, ezindaweni ezihlukene zokushisa okwedlulele, ukuqhutshwa kwayo okushisayo akuguquki kakhulu futhi kugcina ukusebenza kokushisa okuzinzile, okuphakeme kakhulu kunoboya bedwala obujwayele ukuhluleka umswakama emazingeni okushisa aphansi kanye ne-calcium silicate ngokunyuka okungazelelwe kokushisa okushisayo emazingeni okushisa aphezulu.

Uyini umphumela wokushisa oshisayo we-nano airgel ezwakele?

Ikhwalithi ephezulu ye-nano airgel izwakele yelashwe nge-hydrophobicity, futhi izinga le-hydrophobicity lingafinyelela ngaphezu kwama-98%. Ngisho noma isendaweni enomswakama futhi enomswakama ophezulu isikhathi eside, ngeke imunce umswakama.
Kodwa-ke, izinto ezisetshenziswayo zokuvikela ezijwayelekile ezifana noboya bedwala kanye noboya bengilazi zizothola ukwehla okungaphezu kuka-50% ekusebenzeni kokufakwa ngemuva kokumunca amanzi, okungaholela nasekugqwaleni kwemishini; Ijeli lomoya elizwakalayo lingagwema le nkinga, ikakhulukazi ezilungele izimo ezimanzi njengobunjiniyela bamakhemikhali, ubunjiniyela basolwandle kanye nobunjiniyela obungaphansi komhlaba.

5. Inobungani nemvelo futhi ayivimbeli ilangabi, namazinga okusebenza okuhambisana nokuphepha

Isisindo somthamo we-airgel esizwayo singama-180 - 300kg/m³ kuphela. Ithambile futhi iyavumelana nezimo, futhi ingasongwa ngokuqondile phezu kwezakhiwo eziyinkimbinkimbi njengamapayipi amise okukhethekile, ama-valve, nama-flange emishini. Ingasikwa futhi inamathiselwe ngaphandle kwefomula eyinkimbinkimbi, ithuthukise kakhulu ukusebenza kahle kokufaka.
Ngesikhathi esifanayo, i-coefficient yayo yokunweba okushisayo iphansi kakhulu, ikwazi ukumelana nokushintshashintsha kwezinga lokushisa okuvamile, futhi ngeke iqhekeke noma siwe ngenxa yokwanda nokuncipha kwezinga lokushisa njengama-castable aqinile. Ukuphila kwayo kwenkonzo yinde izikhathi ezingu-2-3 kunezinto zendabuko, ukunciphisa izindleko zokulondoloza esikhathini esizayo.

3. I-Hydrophobic kanye nomswakama-ubufakazi, ayiboli ezindaweni ezinomswakama

Ingxenye eyinhloko ye-nano airgel ezwakalayo i-silicon dioxide ye-inorganic, engenayo i-asbestos, i-formaldehyde nezinye izinto eziyingozi. Ukusebenza kwayo komlilo kufinyelele ezingeni elingashi le-Class A. Ngeke ikhiphe amagesi anobuthi emazingeni okushisa aphezulu. Ihlangabezana nezidingo zokuvikelwa kwemvelo yezimboni kanye nokuphepha komlilo, futhi ifaneleka ngokukhethekile kumakhemikhali, amandla kagesi kanye nezinkambu zokwakha ezinezidingo eziqinile zokuvikelwa kwemvelo nokuphepha.

I-Rosewool Insulation Refractory Co., Ltd 2. Ububanzi obubanzi bezinga lokushisa elizinzile, obukwazi ukusebenza ngaphansi kwezimo zokushisa eziphakeme neziphansiIngxenye eyinhloko yeabe ne-ultra-low heat conduction engu-<0.018W/(m ・ K), ukuzinza kwebanga lokushisa elibanzi okungu- -200 ℃~1000 ℃, 99.5%+hydrophobic kanye nokuguquguquka kwe-lightweight, futhi angonga amandla ngokuphawulekayo ngaphansi kwezimo zokusebenza ezinzima ezifana nezinga lokushisa eliphezulu/elibandayo elijulile//. Ukuhlanganisa ukulethwa kwasendaweni kanye nezinsizakalo zobuchwepheshe ezenziwe ngezifiso, kuyisinqumo esingcono kakhulu sokuthuthukiswa kokufakwa kwezimboni.
