Kodi mumadziwa bwanji kuchuluka kwamoto kwa nsalu yoletsa moto?

Oxygen index kudziwika njira: nsalu yoyaka, amafunika kudya mpweya wambiri, osati woyaka womwewo, kuchuluka kwa mpweya wofunika kuwotcha sikufanana, malinga ndi kutsimikiza kwa mowa wochepa wa okosijeni panthawi ya kuyaka kwa zinthu, oxygen index mtengo wa zinthu, akhoza kuweruza kuyaka ntchito zakuthupi.

Njira yopingasa ndi njira yowongoka ndiyo njira zodziwika kwambiri zoyezera zinthu zamoto. Mfundo yake yayikulu ndi: mopingasa kapena molunjika kutsina mbali imodzi yachitsanzocho, onjezerani lawi lamoto lofunikira kumapeto kwa chithunzicho, molingana ndi kuyeza kwa liwiro la kuyaka (njira yopingasa) ndi nthawi yoyaka ndi lawi lamoto (njira yowongoka) kuti apereke ndemanga pa ntchito yoyaka moto ya nsalu yotchinga moto yachitsanzocho. Kuyesa koyima kumakhala kolimba kwambiri kuposa 45 ° mayendedwe ndi njira yopingasa.Wopanga nsalu zoletsa moto

Njira yowongoka imagawidwa mu njira yowongoka yowongoka, njira yoyezera momwe ntchito ikugwiritsidwira ntchito, njira yoyesera yowotcha komanso njira yoyezera ntchito yoyaka moto. Njira yowongoka ingagwiritsidwe ntchito kuyesa zomwe zimawotcha moto wa zovala, nsalu zokongoletsera, mahema, ndi zina.Wopanga nsalu zoletsa motoNjira yopendekera imagwiritsidwa ntchito kwambiri pansalu yokongoletsera mkati mwa ndege; Njira yopingasa imagwiritsidwa ntchito makamaka pomata nsalu monga makapeti.Wopanga nsalu zoletsa moto

Njira yoyesera ya nsalu yotchinga moto imagwiritsidwa ntchito makamaka kudziwa kutalika kwa kuwonongeka, nthawi yoyaka mosalekeza komanso nthawi yofukiza yachitsanzocho. Zitsanzo za kukula kwake zinayatsidwa m'chipinda choyatsira chofunikira chokhala ndi gwero loyatsira lofunikira la 12s. Pambuyo pochotsa gwero loyatsira, nthawi yoyaka mosalekeza ndi nthawi yofukiza ya zitsanzozo zidadziwika. Kusuta kukayimitsidwa, kutalika kwa kuwonongeka kumayesedwa molingana ndi njira yolembedwera. Makamaka molingana ndi United States ASTMF1358-1995 "njira yoyezera nsalu yotchinga moto - njira yowongoka" ndi China's GB/T5456-2009 "Textile combustion performance vertical direction test specimen flame spread performance" ndi GB5455-1997 "Textile combustion performance njira” ndi mfundo zina. Miyezo ya dziko la China imafuna nthawi yoyaka nthawi zonse ≤5s, nthawi yofukiza ≤5s, kutalika kwa kuwonongeka ≤150mm. Malinga ndi malo achibale a chitsanzo ndi lawi, akhoza kugawidwa m'njira ofukula, njira yokhotakhota ndi njira yopingasa.

Mlozera wa okosijeni umatanthawuza kuchuluka kwa okosijeni munsalu yoletsa moto mpaka kuyaka. Kawirikawiri, kuchuluka kwa mpweya wa okosijeni wa nsaluyo, kumapangitsa kuti mpweya wa okosijeni uyambe kuyaka, ndipo umakhala wochepa kwambiri; M'malo mwake, nsalu oxygen index ndi otsika, mu otsika mpweya ndende mtengo wosavuta kufika poyatsira. Mlozera wa okosijeni pansi pa 21 ndi nsalu zoyaka moto, ndipo cholozera cha okosijeni pamwamba pa 28 ndi nsalu zotchingira moto.
