Oxygen index yekuona nzira: jira rinopisa, rinoda kushandisa yakawanda yeokisijeni, kwete yakafanana inopisa, huwandu hweokisijeni hunodiwa kupisa hauna kufanana, maererano nekutsunga kwekushandiswa kweokisijeni yakaderera mukupisa kwezvinhu, yakaverengwa. oksijeni indekisi kukosha kwezvinhu, inogona kutonga kupisa kwekuita kwezvinhu.
Horizontal nzira uye yakatwasuka nzira ndiyo nzira dzakajairika dzekuyera zvinhu zvemoto. Nheyo yayo yakakosha ndeiyi: yakatwasuka kana yakatwasuka tsikirira rimwe divi remuenzaniso, wedzera inodiwa gasi murazvo kumagumo emuenzaniso, zvichienderana nechiyero chemutsara wekupisa mwero (yakatwasuka nzira) uye murazvo uye nguva yekupisa moto (yakatwasuka nzira) kutaura pamusoro pekupisa kwejira retardant jira remuenzaniso. Muedzo wakatwasuka wakanyanya kudarika 45° gwara nekwakachinjika.Mugadziri wemachira anopisa moto
Vertical nzira yakakamurwa kuita yakatwasuka kukuvadzwa kureba nzira, yakatwasuka murazvo wekuparadzira kuita kuyerwa nzira, yakatwasuka yekupisa moto yekuyedza nzira uye pamusoro pekupisa kwekuita kuyerwa nzira. Vertical nzira inogona kushandiswa kuyedza mirazvo inodzoreredza zvimiro zvembatya machira, machira ekushongedza, matende, nezvimwe.Mugadziri wemachira anopisa motoTilt nzira inonyanya kushandiswa kune ndege yemukati yekushongedza jira; Iyo yakachinjika nzira inonyanya kushandiswa kugadzira machira semakapeti.Mugadziri wemachira anopisa moto
Iyo murazvo inodzoreredza jira yekuyedza nzira inonyanya kushandiswa kuona kureba kwekukuvadza, inoenderera nguva yekupisa uye kuputa nguva yemuenzaniso. Mienzaniso yeimwe saizi yakavhenekerwa mukamuri inobvira inopisa ine inodiwa sosi yekudzima ye12s. Mushure mekubvisa chitubu chekudzima, nguva yekupisa inoenderera uye nguva yekupfungaira yezvienzaniso zvakaonekwa. Mushure mokunge kusvuta kwamira, kureba kwekukuvadza kunoyerwa maererano nenzira yakatarwa. Kunyanya zvinoenderana neUnited States ASTMF1358-1995 "textile flame retardant performance standard yekuyera nzira - yakatwasuka nzira" uye China's GB/T5456-2009 "Textile combustion performance vertical direction test specimen flame spread performance" uye GB5455-1997 "Textile combustical performance test. nzira” nemimwe mipimo. Mitemo yenyika yeChinese inoda kuenderera mberi kwekupisa nguva ≤5s, kusvuta nguva ≤5s, kukuvadza kureba ≤150mm. Zvinoenderana nenzvimbo yakaenzana yemuenzaniso uye murazvo, inogona kukamurwa kuita yakatwasuka nzira, yakarerekera nzira uye yakachinjika nzira.
Oxygen index inoreva kuwanda kweokisijeni mujira rinodzoreredza moto kusvika pakubatidza. Kazhinji, iyo yakakwirira yeokisijeni indekisi yemucheka, iyo yakakwirira yeokisijeni inotarisirwa kupisa, uye zvishoma zvishoma iyo inopisa; Pane zvinopesana, jira reokisijeni indekisi yakaderera, mune yakaderera okisijeni kukosha kweiyo nyore kusvika painobatidza. Indekisi yeokisijeni iri pasi pe21 machira anopfuta, uye indekisi yeokisijeni iri pamusoro pe28 machira anodzoreredza moto.
