Tsis Siv Neeg Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob

Deepmaterial Luam tawm roj teeb Thermal Runaway Spreading thiab Deflagration

Thaum kawg ntawm Lub Xya Hli, Shenzhen Roj Teeb Kev Lag Luam Association, Adhesive Information, New Material Industry Alliance thiab lwm lub koom haum yuav koom ua ke "2024 Advanced Battery thiab Energy Storage Adhesive Material Technology and Application Innovation Forum and Battery and Energy Storage Material Exhibition". "Deepmaterial" yuav coj cov khoom siv tua hluav taws tshiab uas nws tus kheej txaus siab rau lub rooj sib tham thiab qhia txog cov ntaub ntawv tshaj tawm ntawm "Lub hauv paus ntsiab lus ntawm Roj Teeb Thermal Runaway Spreading and Deflagration Inhibition of Self-Excited Fire Extinguishing Materials and Application Discusion", thiab qhia txog txoj hauv kev loj hlob ntawm tshiab technologies thiab cov ntaub ntawv nrog rau cov loj terminals thiab counterparts.

Thaum Lub Tsib Hlis 15, 2024, hluav taws tau pom thawj zaug ntawm Gateway lub zog cia cog hauv California. Txog rau yav tav su ntawm lub Tsib Hlis 16, qhov hluav taws kub tau ze li ntawm kev tua, tab sis lub chaw nres tsheb roj teeb tau rov qab los. Tom qab 40 tus neeg tua hluav taws thiab tsib lub tshuab hluav taws kub ua haujlwm nyob ib ncig ntawm lub moos rau 11 hnub, qhov hluav taws kub tau kawg tua los ntawm cov nyoob hoom qav taub siv tons ntawm perfluorohexanone tua hluav taws tus neeg sawv cev. Los ntawm qhov hluav taws kub no nyob rau hauv lub zog cia chaw nres tsheb, daim ntawv thov ntawm perfluorohexanone tua hluav taws tus neeg saib xyuas nyob rau hauv lithium roj teeb thiab lwm yam tshiab zog industries tau dhau los ua lub ntsiab lus kub.

"Deepmaterial" tau tsim microcapsule C6F12O perfluorohexanone-raws li cov khoom siv tua hluav taws txij li xyoo 2019. Txij li thaum tsim 50% cov khoom txheej hauv xyoo 2021, microcapsule txheej tus nqi ntawm perfluorohexanone kua tau mus txog 85% -90% dhau ntawm kev lag luam, thiab cov nyhuv thiab tus nqi zoo li polarized.

Tam sim no, lub teb chaws tab tom tsim cov qauv hauv teb chaws rau perfluorohexanone cov tshuaj tua hluav taws, thiab cov pab pawg cuam tshuam tau tsim cov txheej txheem ntawm 《Prefabricated perfluorohexanone fire extinguishing devices》.

Lub extinguishing mechanism ntawm perfluorohexanone zoo ib yam li ntawm HFC125 thiab HFC227ea thiab yog ib tug ua ke ntawm ob extinguishing mechanisms.

"Deepmaterial" yog cov txheej txheem microencapsulation tshwj xeeb los encapsulate perfluorohexanone rau hauv cov khoom sib txuas ntawm 50-300um (rau ntau daim ntawv thov). Piv nrog cov kua perfluorohexanone cov ntaub ntawv, microencapsulated perfluorohexanone tuaj yeem ua rau tsis muaj qhov ntau thiab tsawg ntawm cov nplooj ntawv, yooj yim rau xim txheej, potting adhesives rau rwb thaiv tsev thiab tua hluav taws, thiab lwm yam, uas tuaj yeem siv yam tsis muaj kev teeb tsa los ntawm cov kws tshaj lij, tsis tas yuav teeb tsa txoj kev xav thiab hluav taws xob tswj cov tshuab, thiab tsim nyog rau qhov chaw me me uas raug kho lossis txav tau, thiab qhov chaw tsis muaj hluav taws xob.

Kev npaj ntawm perfluorohexanone tua hluav taws microcapsules

"Deepmaterial" tsim cov ntaub ntawv sib txawv ntawm tus kheej zoo siab tua hluav taws cov ntaub ntawv rau perfluorohexanone microcapsules, nrog rau cov nplooj ntawv, txheej, potting gel thiab lwm yam khoom siv tua hluav taws rau tus kheej. Los ntawm kev txheeb xyuas qhov tseeb, hom khoom no tuaj yeem tshem tawm qhov hluav taws kub ntawm 1 cubic qhov chaw ntawm 718g, uas muaj txiaj ntsig zoo heev. Tom qab kev sim ntawm National Key Laboratory of Fire, thaum lub roj teeb luv luv ua kom sov, cov khoom siv dysprosium excitation hluav taws tua cov khoom ua rau tso tawm perfluorohexanone vaporization ntawm 80-200 degrees Celsius, thiab cov nplaim hluav taws raug tua nws tus kheej tom qab lub roj teeb ntes hluav taws. tom qab 5-11 hnub. Hauv kev sim, tom qab cov nplaim hluav taws tau tua nws tus kheej, cov nplaim taws qhib tau qhia txhua 3 feeb hauv 30 min, thiab tsis muaj qhov hluav taws xob rov qab. Tom qab qhov kev sim, nws tuaj yeem pom tias cov khoom lag luam muaj txiaj ntsig zoo ntawm daim ntawv thov nyob rau hauv thermal runaway ntawm lub roj teeb ntawm tes.
