Isixhobo sokuSungula uMlilo ngokuzenzekela
I-Deepmaterial yokuPapasha iBattery ye-Thermal Runaway eSasaza kunye ne-Deflagration
Ekupheleni kukaJulayi, i-Shenzhen Battery Industry Association, i-Adhesive Information, i-New Material Industry Alliance kunye nezinye iiyunithi ziya kuququzelela ngokudibeneyo "i-2024 Advanced Battery kunye ne-Energy Storage Adhesive Material Technology kunye ne-Application Innovation Forum kunye neBattery kunye ne-Energy Storage Material Exhibition". "I-Deepmaterial" iya kuzisa izixhobo zokucima umlilo zamva nje ezinomdla kwintlanganiso kwaye yabelane ngengxelo yobugcisa "Umgaqo weBattery Thermal Runaway Spreading and Deflagration Inhibition of Self-Excited Fire Extinguing Materials and Application Discussion", kwaye wabelane ngamathuba ophuhliso itekhnoloji entsha kunye nezixhobo ezineetheminali ezinkulu kunye nabalingane.
NgoMeyi 15, 2024, umlilo wabhaqwa okokuqala kwindawo yokugcina amandla eGateway eCalifornia. Ngenjikalanga ye-16 kaMeyi, umlilo waphantse wacinywa, kodwa iibhetri zesitishi ziye zacima. Emva kokuba abacimi bomlilo be-40 kunye neenjini zomlilo ezihlanu zisebenze malunga newashi leentsuku ze-11, umlilo wacinywa ekugqibeleni ngee-helicopter usebenzisa iitoni ze-agent ye-perfluorohexanone yokucima umlilo. Ngalo mlilo kwisikhululo samandla okugcina amandla, ukusetyenziswa kwe-agent ye-perfluorohexanone yokucima umlilo kwiibhetri ze-lithium kunye namanye amashishini anamandla amatsha abe ngumxholo oshushu.
"I-Deepmaterial" iphuhlise i-microcapsule ye-C6F12O esekelwe kwi-perfluorohexanone izinto zokucima umlilo ukususela ngo-2019. Ukusukela ekuphuhlisweni kwe-50% yezinga lokugquma kwemveliso ngo-2021, izinga lokugquma kwe-microcapsule ye-perfluorohexanone lifikelele kwi-85% -90% ngaphaya koshishino, kunye nesiphumo. kwaye iindleko zithande ukuhlukaniswa.
Okwangoku, ilizwe liqulunqa imigangatho yelizwe yee-arhente zokucima umlilo ze-perfluorohexanone, kwaye amaqela afanelekileyo sele equlunqe umgangatho weqela 《Izixhobo zokucima umlilo ze-perfluorohexanone ezilungiselelwe ngaphambili》.
Indlela yokucima i-perfluorohexanone iyafana naleyo ye-HFC125 kunye ne-HFC227ea kwaye yindibaniselwano yeendlela ezimbini zokucima.
"I-Deepmaterial" yinkqubo ekhethekileyo ye-microencapsulation yokufaka i-perfluorohexanone kwiincinci eziqinileyo ze-spherical ze-50-300um (kwizicelo ezahlukeneyo). Xa kuthelekiswa nezixhobo zolwelo perfluorohexanone, microencapsulated perfluorohexanone inokwenziwa ubungakanani unlimited of sheets, kulula ukupeyinta iingubo, ukuncamathelisa imbiza yokugquma kunye nokucima umlilo, njl., ezinokusetyenziswa ngaphandle kofakelo ziingcali, ngaphandle kwesidingo sokufakela imvakalelo enzima kunye nokucima umlilo. iinkqubo zolawulo lwe-elektroniki, kwaye ilungele izithuba ezincinci ezivaliweyo ezizinzileyo okanye ezishukumayo, nalapho umbane ungafumanekiyo.
Ukulungiswa kwe-perfluorohexanone yokucima umlilo i-microcapsules
"I-Deepmaterial" iphuhlisa iindlela ezahlukeneyo zezinto zokucima umlilo ezizithandayo ze-perfluorohexanone microcapsules, kubandakanywa amaphepha, iingubo, i-potting gel kunye nezinye izinto ezizithandayo zokucima umlilo. Ngokuqinisekiswa okusebenzayo, olu hlobo lwemveliso lunokuphelisa umlilo we-1 cubic space kwi-718g, enexabiso eliphezulu kakhulu lezoqoqosho. Emva kovavanyo lweNational Key Laboratory yoMlilo, xa ibhetri imfutshane-yesekethe ifudumala, i-dysprosium impahla yokucima umlilo ibangela ukukhutshwa kwe-perfluorohexanone vaporization kwi-80-200 degrees Celsius, kwaye amadangatye acinywa ngokuzimeleyo emva kokuba ibhetri ibambe umlilo. emva kwe-5-11s. Kuvavanyo, emva kokuba ilangatye licinywe ngokuzimeleyo, ilangatye elivulekileyo laziswa yonke i-3 min ngaphakathi kwe-30 min, kwaye kwakungekho ukuvutha kwakhona. Emva kovavanyo, kunokubonwa ukuba imveliso inexabiso eliphezulu lesicelo kwi-thermal runaway yeseli yebhetri.
