Igitekerezo cya Flame Retardant Rating

Ikizamini cya Flame retardant ni uburyo bukoreshwa mugusuzuma ubushobozi bwibikoresho byo kurwanya ikwirakwizwa ryumuriro. Ibipimo rusange birimo UL94, IEC 60695-11-10, na GB / T 5169.16. Mubisanzwe UL94,Ikizamini cyo gutwika ibikoresho bya plastiki kubice mubikoresho nibikoreshoUrutonde rwa flame retardant yashyizwe mubyiciro 12 ukurikije ubukana bwikizamini nogukoresha: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, na HF2.

Mubisanzwe, ibipimo bikoreshwa cyane bya flame retardant iri hagati ya V-0 kugeza V-2, hamwe na V-0 yerekana imikorere myiza ya flame retardant.

1.1 Ibisobanuro by'ibipimo bine bya Flame Retardant

HB (Gutwika Horizontal):
Igipimo cya HB cyerekana ko ibikoresho byaka buhoro ariko ntibizimya. Ni urwego rwo hasi muri UL94 kandi rusanzwe rukoreshwa mugihe uburyo bwo gupima buhagaritse (V-0, V-1, cyangwa V-2) budakoreshwa.

V-2 (Gutwika Vertical - Urwego 2):
Igipimo cya V-2 bivuze ko ibikoresho bikorerwa ibizamini bibiri bya kabiri 10-isegonda. Umuriro umaze kuvaho, igihe cyo gutwika ibikoresho ntikirenza amasegonda 30, kandi gishobora gutwika ipamba yashyizwe kuri cm 30 munsi. Ariko, urumuri ntirukwirakwira hejuru yumurongo wagaragajwe.

V-1 (Gutwika Vertical - Urwego 1):
Igipimo cya V-1 bivuze ko ibikoresho bikora ibizamini bibiri bya 10-amasegonda. Umuriro umaze gukurwaho, igihe cyo gutwika ibintu ntikirenza amasegonda 30, kandi urumuri ntirukwirakwira hejuru yumurongo wagaragajwe cyangwa gutwika ipamba yashyizwe kuri cm 30 munsi.

V-0 (Gutwika Vertical - Urwego 0):
Igipimo cya V-0 bivuze ko ibikoresho bikora ibizamini bibiri bya kabiri-amasegonda 10. Umuriro umaze gukurwaho, igihe cyo gutwika ibikoresho ntikirenza amasegonda 10, kandi urumuri ntirukwirakwira hejuru yumurongo wagaragajwe cyangwa gutwika ipamba yashyizwe kuri cm 30 munsi.

1.2 Intangiriro Kubindi Bipimo bya Flame Retardant

5VA na 5VB nibiri murwego rwo gutwika ibizamini bya verisiyo ukoresheje urumuri rwa 500W (uburebure bwa 125mm).

5VA (Gutwika Vertical - Urwego 5VA):
Igipimo cya 5VA nicyiciro murwego rwa UL94. Irerekana ko nyuma yumuriro umaze gukurwaho, igihe cyo gutwika ibintu ntikirenza amasegonda 60, urumuri ntirukwirakwira hejuru yumurongo wagaragajwe, kandi umuriro wose utonyanga ntugomba kurenza amasegonda 60.

5VB (Gutwika Vertical - Urwego 5VB):
Urutonde rwa 5VB rusa na 5VA, hamwe n'ibipimo bimwe byo gutwika igihe n'umuriro bikwirakwira.

VTM-0, VTM-1, VTM-2 ni ibyiciro byibikoresho bito (uburebure <0.025mm) mubizamini byo gutwika bihagaritse (uburebure bwa 20mm flame), bikoreshwa kuri firime ya plastike.

VTM-0 (Gutwika inzira ihagaze - Urwego 0):
Igipimo cya VTM-0 bivuze ko nyuma yumuriro umaze gukurwaho, igihe cyo gutwika ibintu ntikirenza amasegonda 10, kandi urumuri ntirukwirakwira hejuru yumurongo wagenwe.

VTM-1 (Gutwika inzira ihagaze - Urwego 1):
Urutonde rwa VTM-1 bivuze ko nyuma yumuriro umaze gukurwaho, igihe cyo gutwika ibintu ntikirenza amasegonda 30, kandi urumuri ntirukwirakwira hejuru yumurongo wagenwe.

VTM-2 (Gutwika inzira ihagaze - Urwego 2):
Igipimo cya VTM-2 gifite ibipimo bimwe na VTM-1.

HBF, HF1, HF2 ni ibyiciro byo gutwika ibizamini bya horizontal ku bikoresho byinshi (uburebure bwa 38mm flame).

HBF (Gutwika Horizontal Ibikoresho Byinshi):
Urutonde rwa HBF rusobanura ko ibintu byifuro byinshi byo gutwika bitarenze mm 40 / min, kandi urumuri rugomba kuzimya mbere yo kugera kumurongo wa 125mm.

HF-1 (Gutwika Horizontal - Urwego 1):
Igipimo cya HF-1 bivuze ko nyuma yumuriro wavanyweho, igihe cyo gutwika ibintu ntikirenza amasegonda 5, kandi urumuri ntirukwirakwira hejuru yumurongo wagenwe.

HF-2 (Gutwika Horizontal - Urwego 2):
Igipimo cya HF-2 bivuze ko nyuma yumuriro umaze gukurwaho, igihe cyo gutwika ibintu ntikirenza amasegonda 10, kandi urumuri ntirukwirakwira hejuru yumurongo wagenwe.

Intego yo Kugerageza Ikizamini cya Flame Retardant

Intego zo gupima amanota ya flame retardant zirimo:

2.1 Gusuzuma imikorere yo gutwika ibikoresho

Kumenya umuvuduko wibikoresho byaka, ikwirakwizwa ryumuriro, hamwe nogukwirakwiza umuriro mugihe cyumuriro bifasha gusuzuma umutekano wacyo, kwiringirwa, hamwe nuburyo bukoreshwa mubirwanya umuriro.

2.2 Kumenya ubushobozi bwo kubika umuriro

Kwipimisha byerekana ubushobozi bwibikoresho byo kuzimya umuriro ukwirakwizwa iyo uhuye ninkomoko yumuriro, ningirakamaro mukurinda kwiyongera kwumuriro no kugabanya ibyangiritse.

2.3 Kuyobora Guhitamo Ibikoresho no Gukoresha

Mugereranije ibikoresho bitandukanye bya flame retardant, ibikoresho byo gupima muguhitamo ibikoresho bikwiye byubwubatsi, ubwikorezi, ibikoresho bya elegitoroniki, nizindi nzego kugirango umutekano urusheho kwiyongera.

2.4 Kubahiriza Amabwiriza n'Ubuziranenge

Ikizamini cya flame retardant gikorwa kenshi ukurikije amategeko yigihugu cyangwa inganda. Iremeza ibikoresho byujuje ibyangombwa byumutekano no kubahiriza ibisabwa byihariye.

Muri make, igeragezwa rya flame retardant itanga amakuru yingenzi muguhitamo ibikoresho, kunoza umutekano wumuriro, no kubahiriza amabwiriza mugusuzuma imyitwarire yaka no kurwanya umuriro.
