Amakhebuli Angabusheki Amalangabi

Izintambo ezingabambezeli ilangabi ziyizintambo eziklanywe ngokukhethekile ezinempahla kanye nokwakhiwa okuthuthukisiwe ukumelana nokubhebhetheka kwamalangabi uma kuba nomlilo. Lezi zintambo zivimbela ilangabi ekusakazeni ubude bekhebula futhi zinciphisa ukukhishwa kwentuthu namagesi anobuthi uma kuba nomlilo. Ngokuvamile zisetshenziswa ezindaweni lapho ukuphepha emlilweni kubalulekile, njengezakhiwo zomphakathi, izinhlelo zokuthutha, nezinsiza zezimboni.

Izinhlobo Zezinto Ezibandakanyeka Kumakhebuli Avimba Umlilo

Izendlalelo ze-polymer zangaphandle nezangaphakathi zibalulekile ekuhlolweni kwe-retardant, kodwa ukwakheka kwekhebula kuhlala kuyisici esibaluleke kakhulu. Ikhebula elakheke kahle, lisebenzisa izinto ezifanele ezingabambezeli ilangabi, lingafinyelela ngempumelelo izici zokusebenza komlilo ezifiselekayo.

Ama-polymers asetshenziswa ngokujwayelekile kwizicelo ezinqanda ilangabi afaka phakathiI-PVCfuthiI-LSZH. Zombili zenziwe ngokukhethekile ngezithasiselo ezingavimbeli ilangabi ukuze zihlangabezane nezidingo zokuphepha komlilo.

Ukuhlolwa Okubalulekile Kwezinto Ezingakhiqizi I-Flame kanye Nokuthuthukiswa Kwekhebula

I-Limiting Oxygen Index (LOI): Lokhu kuhlola kukala ubuncane bokugcwala komoyampilo enhlanganisweni yomoya-mpilo kanye ne-nitrogen ezosekela ukushiswa kwezinto ezisetshenziswayo, ezivezwa njengephesenti. Izinto ezine-LOI engaphansi kuka-21% zihlukaniswa njengezinokusha, kuyilapho lezo ezine-LOI engaphezu kuka-21% zihlukaniswa njengezizicisha ngokwazo. Lokhu kuhlola kunikeza ukuqonda okusheshayo nokuyisisekelo kokuvutha. Amazinga asebenzayo yi-ASTMD 2863 noma ISO 4589

I-Cone Calorimeter: Le divayisi isetshenziselwa ukubikezela ukuziphatha komlilo ngesikhathi sangempela futhi inganquma amapharamitha afana nesikhathi sokuthungela, izinga lokukhululwa kokushisa, ukulahlekelwa okukhulu, ukukhishwa kwentuthu, nezinye izici ezihlobene nezici zomlilo. Izindinganiso eziyinhloko ezisebenzayo yi-ASTM E1354 ne-ISO 5660, i-Cone calorimeter inikeza imiphumela ethembeke kakhulu.

Ukuhlolwa kokuphuma kwegesi ye-Acid (IEC 60754-1). Lokhu kuhlola kulinganisa okuqukethwe kwegesi ye-halogen acid ezintanjeni, kunquma inani le-halogen elikhishwa ngesikhathi sokusha.

Ukuhlolwa kwe-Gas Corrositvity (IEC 60754-2). Lokhu kuhlola kukala i-pH kanye nokusebenza kwezinto ezicekela phansi

Ukuhlolwa kokuminyana kwentuthu noma ukuhlolwa kwe-3m3 (IEC 61034-2). Lokhu kuhlola kukala ukuminyana kwentuthu ekhiqizwa izintambo ezivuthayo ngaphansi kwezimo ezichaziwe. Ukuhlola kwenziwa ekamelweni elinobukhulu obungamamitha angu-3 ngo-3 wamamitha ngo-3 amamitha (yingakho igama elithi 3m³ test) futhi kuhilela ukuqapha ukuncishiswa kokudluliswa kokukhanya ngentuthu ekhiqizwa ngesikhathi sokusha.

Isilinganiso sokuminyana kwentuthu (SDR) (ASTMD 2843). Lokhu kuhlola kukala ukuminyana kwentuthu ekhiqizwa ukushiswa noma ukubola kwamapulasitiki ngaphansi kwezimo ezilawulwayo. Ubukhulu besampula yokuhlola 25 mm x 25 mm x 6 mm
