Nhau - Flame Retardant Ratings uye Testing Standards Summary

Pfungwa yeFlame Retardant Rating

Kuyedza chiyero chemoto chemoto inzira inoshandiswa kuongorora kugona kwechinhu kuramba kupararira kwemoto. Zviyero zvakajairika zvinosanganisira UL94, IEC 60695-11-10, uye GB/T 5169.16. Muchiyero UL94,Kuedza Kupisa kwePlastiki Zvishandiso zveZvikamu muMidziyo uye Zvishandiso, zviyereso zvinodzosa moto zvinoiswa muzvikamu gumi nembiri zvichienderana nekusimba kwebvunzo uye mashandisirwo: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, uye HF2.

Kazhinji, iwo anowanzo shandiswa mirazvo yekudzoreredza ratings kubva kuV-0 kusvika V-2, ine V-0 inoratidza yakanakisa mirazvo inodzoreredza kuita.

1.1 Tsanangudzo dzeIna Flame Retardant Ratings

HB (Horizontal Burning):
HB rating inoratidza kuti zvinhu zvinopisa zvishoma nezvishoma asi hazvidzimi. Ndiro danho rakaderera muUL94 uye rinowanzo shandiswa kana nzira dzekuyedza dzakamira (V-0, V-1, kana V-2) dzisiri kushanda.

V-2 (Kupisa kwakamira - Chikamu 2):
Chiyero cheV-2 chinoreva kuti zvinhu zvinopinda maviri gumi-sekondi akatwasuka bvunzo dzemoto. Mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi makumi matatu, uye inogona kupisa donje yakaiswa masendimita makumi matatu pazasi. Zvisinei, murazvo haufanire kupararira pamusoro pemutsara wakaiswa.

V-1 (Kupisa Kwakajeka - Chikamu 1):
Chiyero cheV-1 chinoreva kuti zvinhu zvacho zvinoedzwa maviri gumi-sekondi akatwasuka emoto bvunzo. Mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi makumi matatu, uye murazvo haufanire kupararira pamusoro pemutsara wakaiswa kana kupisa donje rakaiswa masendimita makumi matatu pazasi.

V-0 (Kupisa Kwakajeka - Chikamu 0):
Chiyero cheV-0 chinoreva kuti zvinhu zvacho zvinopinda mayedzo maviri egumi-sekondi akatwasuka emoto. Mushure mekunge murazvo wabviswa, nguva yekupisa kwezvinhu haipfuuri masekonzi gumi, uye murazvo haufanire kupararira pamusoro pemutsara wakaiswa kana kupisa donje rakaiswa masendimita makumi matatu pazasi.

1.2 Nhanganyaya kune Dzimwe Flame Retardant Ratings

5VA uye 5VB ndeyeiyo yakatwasuka yekupisa bvunzo yemhando uchishandisa 500W bvunzo murazvo (125mm murazvo kureba).

5VA (Vertical Burning - 5VA Level):
Iyo 5VA chiyero chikamu mune iyo UL94 standard. Zvinoratidza kuti mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi makumi matanhatu, murazvo haufanire kupararira pamusoro pemutsara wakaiswa, uye chero marimi anodonha haafanire kudarika masekonzi makumi matanhatu.

5VB (Vertical Burning - 5VB Level):
Chiyero che5VB chakafanana ne5VA, ine nzira imwechete yekupisa nguva uye kupararira kwemurazvo.

VTM-0, VTM-1, VTM-2 zvikamu zvezvinhu zvitete (ukobvu <0.025mm) mumiyedzo yekupisa yakatwasuka (20mm murazvo kureba), inoshanda kumafirimu epurasitiki.

VTM-0 (Vertical Tray Burning – Level 0):
Chiyero cheVTM-0 chinoreva kuti mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi gumi, uye murazvo haufanire kupararira pamusoro pemutsara wakaiswa.

VTM-1 (Vertical Tray Burning – Level 1):
Chiyero cheVTM-1 chinoreva kuti mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi makumi matatu, uye murazvo haufanire kupararira pamusoro pemutsara wakaiswa.

VTM-2 (Vertical Tray Burning – Level 2):
Chiyero cheVTM-2 chine maitiro akafanana neVTM-1.

HBF, HF1, HF2 zvikamu zveyakachinjika yekupisa bvunzo pazvinhu zvine furo (38mm murazvo kureba).

HBF:
Chiyero cheHBF chinoreva kuti kupisa kwefuro hakupfuuri 40 mm/min, uye murazvo unofanira kudzima usati wasvika pamutsara wamaka 125mm.

HF-1 (Horizontal Burning – Level 1):
Chiyero cheHF-1 chinoreva kuti mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi mashanu, uye murazvo haufanire kupararira pamusoro pemutsara wakaiswa.

HF-2 (Horizontal Burning – Level 2):
Chiyero cheHF-2 chinoreva kuti mushure mekunge murazvo wabviswa, nguva yekupisa yezvinhu haipfuuri masekonzi gumi, uye murazvo haufanire kupararira pamusoro pemutsara wakaiswa.

Chinangwa cheFlame Retardant Rating Testing

Zvinangwa zvekuvheneka chiyero chemoto zvinosanganisira:

2.1 Kuongorora Kuita Kwekupisa Kwezvinhu

Kuona kumhanya kwekupisa kwechinhu, kupararira kwemurazvo, uye kupararira kwemoto pasi pemamiriro emoto kunobatsira kuongorora kuchengetedzwa kwayo, kuvimbika, uye kukodzera kwezvishandiso zvinodzivirira moto.

2.2 Kusarudza Kugona Kudzoserwa Nomoto

Kuedza kunoratidza kugona kwechinhu kudzvanya moto unopararira kana waiswa panzvimbo yemoto, izvo zvakakosha kudzivirira kukwira kwemoto uye kuderedza kukuvadzwa.

2.3 Kutungamira Kusarudzwa uye Kushandiswa kwezvinhu

Nekuenzanisa zvinhu zvakasiyana-siyana zvinodzoreredza moto, zviyamuro zvekuedza pakusarudza zvinhu zvakakodzera zvekuvaka, zvekufambisa, zvemagetsi, uye zvimwe minda kuwedzera kuchengetedzwa kwemoto.

2.4 Kutevedzera Mitemo neMitemo

Kuyedza kudzoreredza moto kunowanzoitwa zvinoenderana nenyika kana indasitiri mirau. Inovimbisa kuti zvinhu zvinosangana nekuchengetedza uye kutevedzera zvinodiwa kune chaiwo maapplication.

Muchidimbu, kuyedza kudzoreredza chiyero chemoto kunopa dhata yakakosha yekusarudzwa kwezvinhu, kuvandudzwa kwekuchengetedza moto, uye kutevedzera mutemo nekuongorora maitiro ekupisa uye kuramba kwemoto.
