Mea Fa'atama'ia Afi
Deepmaterial Publish Battery Thermal Runaway Spreading and Deflagration
I le faaiuga o Iulai, Shenzhen Battery Industry Association, Adhesive Information, New Material Industry Alliance ma isi iunite o le a faʻatasi faʻatasi "2024 Advanced Battery and Energy Storage Adhesive Material Technology and Application Innovation Forum ma Battery and Energy Storage Material Exhibition". O le "Deepmaterial" o le a aumaia mea fou e tineia ai le afi i le fonotaga ma faʻasoa le lipoti faʻapitoa o le "Principle of Battery Thermal Runaway Spreading and Deflagration Inhibition of Self-Excited Fire Extinguishing Materials and Application Discussion", ma faʻasoa avanoa tau atinaʻe o tekonolosi fou ma meafaitino fa'atasi ai ma fa'amaufa'ailoga tetele ma fa'atusa.
I le aso 15 o Me, 2024, na muamua iloa ai se afi i le Gateway energy storage plant i Kalefonia. E oo atu i le aoauli o le aso 16 o Me, ua toeitiiti lava tineia le afi, ae ua toe ola maa a le ofisa. Ina ua maeʻa le 40 tagata fuimu ma le lima afi afi na galulue i le uati mo le 11 aso, na iu lava ina tape le afi e helikopa e faʻaaoga ai tone o le perfluorohexanone afi faʻaumatia afi. E ala i lenei afi i totonu o le eletise e teu ai le malosi, o le faʻaaogaina o le perfluorohexanone afi faʻamaʻi afi i maa lithium ma isi pisinisi fou malosi ua avea ma autu vevela.
"Deepmaterial" o loʻo atinaʻe microcapsule C6F12O perfluorohexanone-faʻavae afi tineia mea talu mai le 2019. Talu mai le atinaʻeina o le 50% o le faʻapipiʻiina o oloa i le 2021, o le microcapsule coating rate of perfluorohexanone liquid ua oʻo atu i le 85% -90% i tua atu o le alamanuia, ma le aafiaga. ma le tau e masani ona polarized.
I le taimi nei, o loʻo faʻatulagaina e le atunuʻu tulaga faʻale-atunuʻu mo faʻamaʻi afi afi perfluorohexanone, ma o vaega talafeagai ua uma ona faʻatulagaina le tulaga faʻavae o le 《Prefabricated perfluorohexanone afi tineui masini》.
O le masini tineia o le perfluorohexanone e tutusa ma le HFC125 ma le HFC227ea ma o se tuufaatasiga o auala e lua e tineia ai.
"Deepmaterial" o se faiga faʻapitoa microencapsulation e faʻapipiʻi ai le perfluorohexanone i totonu o vaega faʻamalo spherical o le 50-300um (mo faʻaoga eseese). Pe a faatusatusa i mea vai perfluorohexanone mea, microencapsulated perfluorohexanone e mafai ona faia i le faatapulaaina lapoa o laupepa, faigofie e vali coatings, potting adhesives mo insulation ma tineia afi, ma isi, lea e mafai ona faaaoga e aunoa ma le faapipiiina e tagata tomai faapitoa, e aunoa ma le manaomia e faapipii sensing faigata ma. faiga fa'aeletoroni fa'atonu, ma e talafeagai mo tama'i nofoaga pupuni e fa'amautu pe fe'avea'i, ma e le maua ai le eletise.
Sauniuniga o microcapsules tineia afi perfluorohexanone
O le "Deepmaterial" e atiina ae ituaiga eseese o mea e tapeina ai le afi mo le perfluorohexanone microcapsules, e aofia ai laupepa, faʻapipiʻi, potting gel ma isi mea e faʻafefe ai le afi. E ala i faʻamaoniga faʻatino, o lenei ituaiga o oloa e mafai ona faʻaumatia le afi o le 1 kupita avanoa i le 718g, lea e maualuga tele le tau tamaoaiga. A maeʻa le suʻega a le National Key Laboratory of Fire, pe a faʻamafanafanaina le puʻupuʻu puʻupuʻu, o le dysprosium material excitation afi tineia mea e faʻaosoina ai le faʻasaʻoina o le perfluorohexanone vaporization i le 80-200 tikeri Celsius, ma o le afi e tineia faʻatasi pe a uma le afi afi. ina ua mavae 5-11s. I le faʻataʻitaʻiga, ina ua uma ona tineia le afi, na faʻafeiloaʻi le afi mumu i le 3 min i totonu ole 30 min, ma e leai se toe faʻafefe. A maeʻa le faʻataʻitaʻiga, e mafai ona vaʻaia o le oloa o loʻo i ai se aoga maualuga i le faʻaogaina o le vevela o le cell maa.
Perfluorohexanone microcapsule mea e tineia afi
afi fa'aola e le tagata lava ia
tineia granules
Fa'ato'aga fa'atosina afi fa'ato'aga
Fa'ato'a fa'aola e le tagata lava ia afi fa'alavelave fa'alavelave
E mafai ona faia microcapsules Perfluorohexanone i ituaiga eseese o mea e tineia afi, e pei o le laulau, lima; lipine, ufiufi, kelu ma isi.
Fa'aaogāina o mea e tineia mu afi perfluorohexanone microcapsule
