Izintambo Ezivimbela Umlilo

Izintambo ezivimbela ilangabi ziyizintambo eziklanywe ngokukhethekile ezinezinto zokwakha kanye nokwakhiwa okulungiselelwe ukumelana nokusabalala kwamalangabi uma kwenzeka umlilo. Lezi zintambo zivimbela ilangabi ukuthi lingasabalali ngobude bekhebula futhi zinciphise ukukhishwa kwentuthu kanye namagesi anobuthi uma kwenzeka umlilo. Zivame ukusetshenziswa ezindaweni lapho ukuphepha komlilo kubalulekile khona, njengezakhiwo zomphakathi, izinhlelo zokuhamba, kanye nezindawo zezimboni.

Izinhlobo Zezinto Ezihilelekile Ezintambo Ezivimbela Umlilo

Izendlalelo ze-polymer zangaphandle nezangaphakathi zibalulekile ekuhlolweni okuvimbela umlilo, kodwa ukwakheka kwekhebula kusalokhu kuyisici esibaluleke kakhulu. Ikhebula eliklanywe kahle, elisebenzisa izinto ezifanele ezivimbela umlilo, lingafeza ngempumelelo izici zokusebenza komlilo ezifiselekayo.

Ama-polymer asetshenziswa kakhulu ekusetshenzisweni okuvimbela umlilo afaka phakathiI-PVCfuthiI-LSZHZombili zenziwe ngokukhethekile ngezithasiselo ezivimbela umlilo ukuze kuhlangatshezwane nezidingo zokuphepha emlilweni.

Ukuhlolwa Okubalulekile Kwezinto Ezivimbela Umlilo Nokuthuthukiswa Kwekhebula

I-Limiting Oxygen Index (LOI): Lokhu kuhlola kulinganisa ukuhlushwa okuncane kwe-oxygen engxubeni ye-oxygen ne-nitrogen ezosekela ukusha kwezinto, okuvezwa njengephesenti. Izinto ezine-LOI engaphansi kuka-21% zihlukaniswa njengezingasha, kanti lezo ezine-LOI engaphezu kuka-21% zihlukaniswa njengezizicishayo. Lokhu kuhlola kunikeza ukuqonda okusheshayo nokuyisisekelo kokusha. Izindinganiso ezisebenzayo yi-ASTMD 2863 noma i-ISO 4589

I-Cone Calorimeter: Le divayisi isetshenziselwa ukubikezela ukuziphatha komlilo ngesikhathi sangempela futhi inganquma amapharamitha afana nesikhathi sokushisa, izinga lokukhishwa kokushisa, ukulahleka kwesisindo, ukukhishwa kwentuthu, nezinye izakhiwo ezihambisana nezici zomlilo. Izindinganiso eziyinhloko ezisebenzayo yi-ASTM E1354 kanye ne-ISO 5660, i-Cone calorimeter inikeza imiphumela ethembekile kakhudlwana.

Ukuhlolwa kokukhishwa kwegesi ye-asidi (IEC 60754-1). Lokhu kuhlolwa kulinganisa okuqukethwe kwegesi ye-asidi ye-halogen ezintanjeni, kunquma inani le-halogen ekhishwa ngesikhathi sokushisa.

Ukuhlolwa Kokugqwala Kwegesi (IEC 60754-2). Lokhu kuhlolwa kulinganisa i-pH kanye nokuqhuba kwezinto ezigqwalisayo

Ukuhlolwa kobuningi bentuthu noma ukuhlolwa okungu-3m3 (IEC 61034-2). Lokhu kuhlolwa kulinganisa ubuningi bentuthu ekhiqizwa yizintambo ezishiswayo ngaphansi kwezimo ezichaziwe. Ukuhlolwa kwenziwa ekamelweni elinobukhulu obungamamitha ama-3 ngamamitha ama-3 ngamamitha ama-3 (yingakho kuthiwa ukuhlolwa okungu-3m³) futhi kuhilela ukuqapha ukwehla kokudluliselwa kokukhanya ngentuthu ekhiqizwa ngesikhathi sokushisa.

Isilinganiso sobuningi bentuthu (SDR) (ASTMD 2843). Lokhu kuhlola kulinganisa ubukhulu bentuthu ekhiqizwa ukushiswa noma ukubola kwepulasitiki ngaphansi kwezimo ezilawulwayo. Ubukhulu besampula yokuhlola 25 mm x 25 mm x 6 mm
