Iyini i-Airgel Coatings? .
Izembozo ze-Airgel ziyizinto ezingasindi kakhulu ezenziwe ngamajeli lapho ingxenye yoketshezi ishintshwa ngegesi. Lokhu kubanika isakhiwo esifana nesipontshi esigcwele amaphakethe omoya amancane. Ngenxa yalokhu, baphakathi kwe-insulators engcono kakhulu eyaziwayo. Nabo ngokufanayo bamelana nomswakama, amakhemikhali, futhi iyashisa. Uma isetshenziswa njenge-coating, ama-aerogel enza isithiyo esivikelayo phezu kwezindawo zensimbi. Lesi sivimbelo sisiza ukuyeka ukugqwala futhi sigcine ukushisa ukuthi kunganyakazi noma kuphume futhi ngokushesha. Izithako eziyinhloko ngokuvamile zihlanganisa i-silica noma amafomu amasha njengama-aerogel asekelwe ku-graphene. Lezi zinguqulo ezithuthukisiwe zinikeza ukusebenza okungcono kakhulu. Ungafunda kabanzi mayelana nocwaningo lwesayensi lwalezi zakhiwo zokuhlala ezivikela kakhulu ku- lesi sixhumanisi.
Kungani Kusetshenziswa I-Airgel Coatings Yokuvikeleka Kwe-Rust Nokuphathwa Kwe-Thermal? .
Izingxenye zensimbi zembulwe ekubeni manzi, usawoti, noma isimo sezulu esibi sivame ukuguga ngokuhamba kwesikhathi. Opende bendabuko noma okusonga kunganciphisa lokhu kodwa kuvame ukuwa ngaphansi kwezimo ezinzima. Izembozo ze-Airgel zilungisa lokhu ngokukhiqiza okomile, ungqimba oluzinzile oluvimba amanzi nomoya-mpilo– izimbangela ezimbili ezibalulekile zokugqwala. Ngesikhathi esifanayo, baphatha kahle ukushisa. I-nanostructure yabo ibamba umoya kahle kangangokuthi ukudluliswa kokushisa kwehle kakhulu. Lesi sici esingamawele sibenza bafaneleke emikhakheni lapho kokubili ukuwohloka nokulawula izinga lokushisa kubalulekile. Ngokwesibonelo, imikhumbi, amapayipi, kanye nezinkundla ezingasogwini zibhekana nokuchayeka njalo emanzini anosawoti kanye nokuguquguquka okukhulu kwezinga lokushisa. Ukuqedwa kwe-Airgel kuvikelekile ngokumelene nezinkinga zombili ngesikhathi esisodwa. Yingakho abaklami bephendukela kubo kaningi.
Isetshenziswa Kanjani I-Airgel Coatings? .
Ukusebenzisa izembozo ze-airgel akulula kunalokho ongakukholelwa. Okokuqala, ubuso budinga ukuhlanzwa ngokuphelele ukuze kuqedwe uwoyela, uthuli, noma upende omdala. Khona-ke, impahla ye-airgel– ngokuvamile ku-slurry noma uhlobo olufuthwayo– isetshenziswa kusetshenziswa amabhulashi, amarola, noma izifutho. Okunye ukuhlukahluka kuza njengama-feelds akhiwe ngaphambili angasongwa emapayipini noma emathangeni okugcina. Lezi zinzwa kulula ukumisa nokusika ngosayizi. Umhlahlandlela ojulile wokufaka ama-airgel felts ezindongeni unikezwa ku leli khasi lewebhu. Ngemva kokufaka isicelo, isiphetho siyoma futhi sibophene kahle phezulu. Ihlala iguquguquka, ngakho-ke ngeke iphuke lapho insimbi inwebeka noma ithola ukuguqulwa kwezinga lokushisa. Ukugcina kuncishisiwe, futhi ungqimba luhlala iminyaka eminingi ngaphandle kokuxebuka noma ukuchitha ukusebenza kahle.
Izicelo ze-Airgel Coatings for Corrosion Protection and Thermal Administration .
Lezi ziqephu zisetshenziswa kuzilungiselelo eziningi zomhlaba wangempela. Emkhakheni kawoyela negesi, amapayipi ahamba ogwadule nezilwandle ngokufanayo. Ukuqedwa kwe-Airgel kugcina kungagqwali futhi kunciphise ukulahlekelwa ukufudumala ngesikhathi sokuthutha uketshezi olushisayo. Emoyeni wasolwandle, izikebhe zemikhumbi nezitezi zihlala zivikelekile ekufuthweni kukasawoti ngenkathi zibuye zipholile ngenkathi yasehlobo. Izinkampani zasemkhathini zizisebenzisa ezingxenyeni zendiza ukuze zinakekele ukushintsha kwezinga lokushisa ngokushesha ezindaweni eziphakeme. Futhi emandleni avuselelekayo, amasistimu okushisa elanga ancike ekufakweni kwe-airgel ukugcina imfudumalo ngaphakathi kwabashisekeli. Ngaphandle kokusetshenziswa kwezentengiselwano, izakhiwo ezindaweni ezibandayo zisebenzisa amasistimu odonga asekelwe ku-aerogel ukunciphisa izindleko zokushisisa nokuvikela ukugqwala kwezakhiwo.. Ukuvumelana nezimo kwalokhu kwaziswa kuyaqhubeka kukhula. Ukuze uthole okubanzi cabanga kahle ukuthi ama-nanomaterials afana ne-graphene aziguqula kanjani izinkambu eziningi, bona lesi sisetshenziswa.
Imibuzo Evame Ukubuzwa Mayelana Nezingubo Ze-Airgel Zokuphepha Kwe-Rust Nokuphathwa Kwe-Thermal .
1. Ingabe ukuqedwa kwe-airgel kuyabiza?
Abiza kakhulu kusengaphambili kunamapende avamile, kodwa zihlala isikhathi eside futhi zinciphisa izindleko zokuzigcina. Ngokuhamba kwesikhathi, balondoloza ukheshi.
2. Ingabe zingasetshenziswa ngaphandle?
Yebo. Zenzelwe ukunakekela ukukhanya kwe-UV, imvula, futhi izinga lokushisa liyashintsha ngaphandle kokuwohloka.
3. Ingabe babhekana nazo zonke izinsimbi?
Banamathela kahle ensimbi, i-aluminium, ithusi, nezinye izinsimbi ezijwayelekile. Ukulungiselela indawo engaphezulu kuyisihluthulelo sebhondi eqinile.
4. Ungqimba kufanele lube lukhulu kangakanani?
Kuya emsebenzini. Okokufaka okushisayo, 2– 5 mm ngokuvamile kwanele. Okwezindawo zokugqwala ezinzima, kungase kudingeke ungqimba olukhulu.
5. Ingabe bavikelekile ukuze banakekele?
Izingubo zesimanje ze-airgel azinabo ubuthi futhi azinabungozi uma zisetshenziswa njengokuqondiswa. Hlala uthobela imiyalelo yokuphepha yomenzi.
6. Ingabe zingapendwa ngaphezulu?
Yebo. Inqwaba yezendlalelo ze-airgel zamukela amajazi aphezulu ukuze abe nomthunzi noma ukuphepha okwengeziwe ngaphandle kokuchitha amandla azo okuvikela.
7. Ingabe banezela isisindo esiningi?
Cha. Ama-aerogels aphakathi kwemikhiqizo eqinile elula. Ngisho nongqimba oluwugqinsi luhlanganisa isisindo esincane kakhulu ezinhlakeni.
8. Ziqhathaniswa kanjani ne-insulation ejwayelekile?
Banikeza ukufakwa okufanayo okufanayo noma okungcono kunogqinsi oluncane kakhulu. Leli gumbi lilondoloza, ikakhulukazi ezindaweni eziqinile njengezikhala zenjini yomkhumbi noma izindonga zokwakha.
9. Ingabe zingashi?
Iningi lama-aerogel asuselwa ku-silica awashi futhi angamelana namazinga okushisa ngaphezulu 500 °C. Izinhlobo ezithuthukisiwe ze-graphene nazo zingenza kangcono kakhulu.
10. Ngingazithola kuphi?
