Ingqikelelo yokuRetardant yeFrime

Uvavanyo lokulinganisa idangatye yindlela esetyenziswayo ukuvavanya amandla esixhobo sokumelana nokusasazeka kwedangatye. Imigangatho eqhelekileyo iquka i-UL94, i-IEC 60695-11-10, kunye ne-GB / T 5169.16. Kumgangatho we-UL94,Uvavanyo lokutsha kwezinto zePlastiki kuMacandelwana kwiZixhobo kunye neZixhobo, i-flame retardant ratings ihlelwa ngamanqanaba e-12 ngokusekelwe kwi-stringency yovavanyo kunye nesicelo: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, kunye ne-HF2.

Ngokuqhelekileyo, ukulinganisa kwe-flame retardant esetyenziswa ngokuqhelekileyo ukusuka kwi-V-0 ukuya kwi-V-2, kunye ne-V-0 ebonisa ukusebenza kakuhle kwe-flame retardant.

1.1 IiNkcazo zeNkalo ezine zeNkangala yokuKhawuleza

HB (Ukutshisa okuthe tye):
Ukulinganisa kwe-HB kubonisa ukuba izinto ezitsha ngokukhawuleza kodwa azicimi. Lelona nqanaba lisezantsi kwi-UL94 kwaye lidla ngokusetyenziswa xa iindlela zovavanyo oluthe nkqo (V-0, V-1, okanye V-2) zingasebenzi.

I-V-2 (Ukutshiswa ngokuthe nkqo – iNqanaba lesi-2):
Ukulinganisa kwe-V-2 kuthetha ukuba izinto zihamba kwiimvavanyo ezimbini ze-10 zesibini ze-vertical flame. Emva kokuba ilangatye lisusiwe, ixesha lokutshiswa kwezinto eziphathekayo alidluli imizuzwana engama-30, kwaye linokutshisa ikotoni ebekwe kwi-30 cm ngaphantsi. Nangona kunjalo, ilangatye malinganwenweli ngaphezu komgca ophawulweyo.
