Umhloli wokuvutha omile futhi ovundlile

Incazelo emfushane:

Ukuhlolwa kokuvutha okuqondile nokuvundlile ngokuyinhloko kubhekisela kumazinga afana ne-UL 94-2006, IEC 60695-11-4, IEC 60695-11-3, GB/T5169-2008, namanye. Lawa mazinga ahlanganisa ukusebenzisa isishisi se-Bunsen esiwusayizi othile kanye nomthombo wegesi othize (i-methane noma i-propane) ukuze uthunge isifanekiso izikhathi eziningi endaweni ethile yobude ne-engeli, kokubili endaweni eqondile nevundlile. Lokhu kuhlola kwenzelwa ukuhlola ukuvutha nobungozi bomlilo besampula ngokulinganisa izici ezifana nemvamisa yokuvutha, ubude besikhathi sokusha, nobude bokusha.

Isicelo

I-UL94 Vertical and Horizontal Flammability Tester isetshenziswa ngokuyinhloko ukuhlola ukuvutha kwezinto ezihlukaniswa njenge-V-0, V-1, V-2, HB, ne-5V. Isebenza emikhiqizweni eyahlukene kagesi neye-elekthronikhi, okuhlanganisa okokukhanyisa, izintambo zikagesi, izinto zikagesi ezinamandla aphansi, izinto zasendlini, amathuluzi omshini, izixhumi zikagesi nezisekeli, izinjini, amathuluzi kagesi, amathuluzi kagesi, namathuluzi kagesi. Le mishini yokuhlola ibuye ilungele izinto zokufakelwa, amapulasitiki obunjiniyela, nezinye izimboni ezibhekene nezinto eziqinile ezivuthayo. Ingasetshenziselwa ukwenza izivivinyo zokuvutha ocingweni nasezintweni zokuvikela ikhebula, izinto eziphrintiwe zebhodi lesifunda, ama-insulators e-IC, nezinye izinto eziphilayo. Ukuhlola kuhilela ukubeka isifanekiso phezu komlilo, usishise imizuzwana engu-15, ucime imizuzwana engu-15, bese uhlola izinga lokushiswa kwalo ngemva kokuphinda ukuhlolwa.
