Microencapsulated Self-activated Fire Extinguishing Gel

Txheej | Shua Material | Nrog Cov Hluav Taws Xob Cables

Deepmaterial yog nws tus kheej muaj hluav taws kub tua hluav taws cov chaw tsim khoom hauv Suav teb, tau tsim ntau hom kev zoo siab rau tus kheej perfluorohexanone cov khoom tua hluav taws kom lub hom phiaj ntawm kev sib kis ntawm thermal runaway thiab deflagration tswj nyob rau hauv lub zog tshiab roj teeb, nrog rau cov nplooj ntawv, coatings, potting kua nplaum thiab lwm yam excitation hluav taws. - cov ntaub ntawv tua hluav taws. Cov khoom no tuaj yeem tshem tawm hluav taws hauv 1 cubic qhov chaw ntawm 718g thiab muaj txiaj ntsig zoo heev. Tom qab kev sim los ntawm National Fire Key Laboratory, thaum lub roj teeb luv luv thiab cua sov, perfluorohexanone tua hluav taws ua rau vaporization thiab tso tawm ntawm perfluorohexanone ntawm 80-200 degrees. Tom qab lub roj teeb ntes hluav taws, cov nplaim hluav taws yuav tua tau tom qab 5-11 vib nas this. Hauv kev sim, tom qab cov nplaim hluav taws tau tua nws tus kheej, lub nplaim qhib tau qhia txhua 3 feeb rau 30 feeb, thiab tsis muaj hluav taws xob rov qab. Los ntawm kev sim, nws tuaj yeem pom tau tias cov khoom no muaj cov ntawv thov siab heev nyob rau hauv cov nqe lus ntawm roj teeb core thermal runaway.

Hauj lwm yam khoom:

* Siv cov khoom siv hluav taws xob tua hluav taws uas raug lees paub thoob ntiaj teb thiab hauv tsev.

* Tsis siv neeg qhib qhov tso tawm cov khoom siv hluav taws xob tua hluav taws thaum raug kub hnyiab.

* Tau yooj yim ntsia tau rau hauv qhov chaw nqaim thiab qhov chaw siab tshaj.

* Tau yooj yim tshem tawm yam tsis muaj kev puas tsuaj rau cov khoom nws tus kheej.

* Nws tuaj yeem qhib tau rau hauv qhov kub ntawm 80-150 degrees Celsius.

* Teb tam sim ntawd thaum muaj hluav taws kub hauv qhov chaw muab, tshem tawm hluav taws thaum ntxov.

* Tsis txhob tso cov vapors lossis gases thaum lub sijhawm ua haujlwm.

Hluav taws kub extinguishing mechanism: Cov khoom siv hauv paus ntawm microcapsule nws tus kheej exciting hluav taws tua cov khoom tsis muaj xim thiab tsis muaj ntxhiab. Lawv muab khaws cia rau hauv cov kua dej ntawm chav tsev kub. Microcapsule self-exciting fire extinguishing cov ntaub ntawv muaj xws li a cov khoom siv hauv paus uas yog technically synthesized rau hauv nano-microcapsule hais, uas yog tov nrog lwm cov ntaub ntawv los ua flakes, xov hlau los yog granular coatings. Lub tshuab tua hluav taws yog tua hluav taws los ntawm ob qho tib si lub cev thiab tshuaj lom neeg:

Microencapsulated Self-Energizing Hluav Taws Extinguishing Sheet Gels

(1) Cov tshuaj tua hluav taws tua hluav taws, piv txwv li, ntes cov dawb radicals, txiav tawm cov saw hlau cov tshuaj tiv thaiv uas ua rau cov nplaim taws sib kis, yog li tiv thaiv kev txhim kho ntawm hluav taws;

(2) Lub cev hluav taws tua hluav taws yog lub ntsiab hluav taws tua hluav taws ntawm cov khoom siv no, uas yog, los ntawm lub zog thermal txav ntawm cov molecules kom tshem tawm cov cua kub ntau, thiaj li ua tiav cov nyhuv txias, nws muaj peev xwm nqus tau cov cua sov heev. tuaj yeem ua kom cov nplaim hluav taws poob sai sai, uas tseem cuam tshuam cov saw hlau cov tshuaj tiv thaiv ntawm combustion.
