Lingaliro la Flame Retardant Rating

Kuyesa kwa retardant ndi njira yomwe imagwiritsidwa ntchito poyesa kuthekera kwa chinthu kukana kufalikira kwa lawi. Miyezo wamba imaphatikizapo UL94, IEC 60695-11-10, ndi GB/T 5169.16. Muyeso wa UL94,Kuyesa Kutentha Kwazida Zapulasitiki Zazigawo Zazida ndi Zamagetsi, mavoti oletsa moto amagawidwa m'magulu 12 kutengera kulimba kwa mayeso ndi kugwiritsa ntchito kwake: HB, V-2, V-1, V-0, 5VA, 5VB, VTM-0, VTM-1, VTM-2, HBF, HF1, ndi HF2.

Nthawi zambiri, mavoti oletsa malawi omwe amagwiritsidwa ntchito kwambiri amachokera ku V-0 mpaka V-2, pomwe V-0 ikuwonetsa magwiridwe antchito abwino kwambiri oletsa moto.

1.1 Matanthauzo a Mavoti Anayi Oletsa Moto Wamoto

HB (Kuwotcha Kopingasa):
Kuyeza kwa HB kumasonyeza kuti zinthuzo zimayaka pang'onopang'ono koma sizizimitsa zokha. Ndilo mulingo wotsikitsitsa mu UL94 ndipo umagwiritsidwa ntchito ngati njira zoyesera zoyima (V-0, V-1, kapena V-2) sizikugwira ntchito.

V-2 (Kuwotcha Moyima - Gawo 2):
Kuyeza kwa V-2 kumatanthauza kuti zinthuzo zimayesedwa ndi 10-sekondi ziwiri zoyima zamoto. Lawi lamoto likachotsedwa, nthawi yoyaka moto sipitilira masekondi 30, ndipo imatha kuyatsa thonje yomwe imayikidwa pansi pa 30 cm. Komabe, lawi lamoto liyenera kufalikira pamwamba pa mzere wolembedwa.

V-1 (Kuwotcha Moyima - Gawo 1):
Kuyeza kwa V-1 kumatanthauza kuti zinthuzo zimayesedwa ndi 10-sekondi ziwiri zoyima zamoto. Lawi lamoto litachotsedwa, nthawi yoyaka moto sidutsa masekondi a 30, ndipo lawi lamoto liyenera kufalikira pamwamba pa mzere wodziwika kapena kuyatsa thonje loyikidwa 30 cm pansi.

V-0 (Kuwotcha Moyima - Gawo 0):
Kuyeza kwa V-0 kumatanthauza kuti zinthuzo zimayesedwa ndi 10-sekondi ziwiri zowongoka zamoto. Lawi lamoto litachotsedwa, nthawi yoyaka moto sidutsa masekondi 10, ndipo lawi lamoto liyenera kufalikira pamwamba pa mzere wodziwika kapena kuyatsa thonje lomwe limayikidwa 30 cm pansi.

1.2 Chiyambi cha Magawo Ena Oletsa Moto Wamoto

5VA ndi 5VB ndi m'gulu la mayeso oyaka moto pogwiritsa ntchito lawi loyesa la 500W (125mm lawi lawi).

5VA (Kuwotcha Kwambiri - 5VA Level):
Mulingo wa 5VA ndi gulu la UL94 muyezo. Zimasonyeza kuti moto ukachotsedwa, nthawi yoyaka moto siidutsa masekondi 60, lawi lamoto lisamafalikire pamwamba pa mzere wodziwika, ndipo malawi aliwonse akudontha sayenera kupitirira masekondi 60.

5VB (Kuwotcha Molunjika - 5VB Level):
Mlingo wa 5VB ndi wofanana ndi 5VA, wokhala ndi njira yofananira yowotcha nthawi ndi kufalikira kwamoto.

VTM-0, VTM-1, VTM-2 ndi magulu azinthu zoonda (zambiri <0.025mm) pamayeso oyaka molunjika (kutalika kwa lawi la 20mm), zomwe zimagwiritsidwa ntchito pamakanema apulasitiki.

VTM-0 (Vertical Tray Burning - Level 0):
Kuyeza kwa VTM-0 kumatanthauza kuti moto ukachotsedwa, nthawi yoyaka moto sichidutsa masekondi a 10, ndipo lawi lamoto siliyenera kufalikira pamwamba pa mzere wolembedwa.

VTM-1 (Vertical Tray Burning - Level 1):
Kuyeza kwa VTM-1 kumatanthauza kuti moto ukachotsedwa, nthawi yoyaka moto sichidutsa masekondi a 30, ndipo lawi lamoto siliyenera kufalikira pamwamba pa mzere wolembedwa.

VTM-2 (Vertical Tray Burning - Level 2):
Mulingo wa VTM-2 uli ndi njira zofananira ndi VTM-1.

HBF, HF1, HF2 ndi magulu a mayeso oyatsa opingasa pa zinthu zopangidwa thovu (kutalika kwa lawi la 38mm).

HBF (Chinthu Chotambalala Choyaka Choyaka):
Kuyeza kwa HBF kumatanthauza kuti kuthamanga kwa zinthu zokhala ndi thovu sikudutsa 40 mm/min, ndipo lawi lamoto liyenera kuzimitsa lisanafike pamzere wolembedwa wa 125mm.

HF-1 (Kuwotcha Kopingasa - Gawo 1):
Kuyeza kwa HF-1 kumatanthauza kuti moto ukachotsedwa, nthawi yoyaka moto sidutsa masekondi a 5, ndipo lawi lamoto liyenera kufalikira pamwamba pa mzere wolembedwa.

HF-2 (Kuwotcha Kopingasa - Gawo 2):
Kuyeza kwa HF-2 kumatanthauza kuti moto ukachotsedwa, nthawi yoyaka moto sidutsa masekondi a 10, ndipo lawi lamoto liyenera kufalikira pamwamba pa mzere wolembedwa.

Cholinga cha Kuyesa kwa Flame Retardant Rating

Zolinga zoyesa ma retardant retardant ndi:

2.1 Kuwunika Magwiridwe Antchito Oyaka Zinthu

Kuzindikira liwiro la chinthu choyaka, kufalikira kwa lawi, ndi kufalikira kwa moto pamoto kumathandiza kuwunika chitetezo chake, kudalirika kwake, komanso kuyenerera kwazinthu zosagwira moto.

2.2 Kuzindikira Kuthekera Kwakubweza Moto

Kuyezetsa kumawonetsa kuthekera kwa chinthu chopondereza kufalikira kwa lawi likayatsidwa ndi moto, zomwe ndizofunikira kwambiri popewa kukwera kwa moto ndikuchepetsa kuwonongeka.

2.3 Kusankha Zinthu Zotsogola ndi Kugwiritsa Ntchito

Poyerekeza zinthu zosiyanasiyana zoletsa moto, zida zoyesera posankha zida zoyenera zomangira, zoyendera, zamagetsi, ndi magawo ena kuti apititse patsogolo chitetezo chamoto.

2.4 Kutsata Malamulo ndi Miyezo

Kuyesa koletsa moto nthawi zambiri kumachitika molingana ndi malamulo adziko kapena makampani. Imawonetsetsa kuti zida zimakwaniritsa zofunikira zachitetezo ndi kutsata kwazinthu zinazake.

Mwachidule, kuyezetsa kwa retardant retardant kumapereka chidziwitso chofunikira pakusankha zinthu, kukonza chitetezo chamoto, komanso kutsata malamulo powunika momwe kuyaka ndi kukana moto.
