M'dziko la mapulasitiki, kuonetsetsa kuti chitetezo cha moto ndichofunika kwambiri.Kuti awone momwe zinthu za pulasitiki zimawotcha moto, bungwe la Underwriters Laboratories (UL) linapanga muyezo wa UL94.Dongosolo lodziwika bwino lodziwika bwinoli limathandiza kudziwa momwe mapulasitiki amayakira ndikupangitsa opanga kupanga zinthu zotetezeka.
Magulu a UL94: Muyezo wa UL94 umayika zida zapulasitiki m'magulu osiyanasiyana kutengera zomwe amachita pamayeso angapo amoto.Pali magulu asanu: V-0, V-1, V-2, HB, ndi 5VB.
V-0: Zida zomwe zimadutsa gulu la V-0 zimazimitsa mkati mwa masekondi a 10 mutachotsa gwero loyatsira ndipo sizimatulutsa kuyaka kapena kuyaka kupitirira chitsanzocho.
V-1: Zida zomwe zimadutsa gulu la V-1 zimazimitsa mkati mwa masekondi a 30 ndipo sizimatulutsa kuyaka koyaka kapena kowala kuposa chitsanzocho.
V-2: Zida zomwe zimatchedwa V-2 zimazimitsa mkati mwa masekondi a 30 koma zimakhala ndi moto wochepa kapena woyaka moto utachotsedwa.
HB: Gulu la Horizontal burn (HB) limagwira ntchito kuzinthu zomwe sizikukwaniritsa zofunikira pagulu loyima koma sizimafalitsa lawi lamoto pachitsanzo panthawi ya mayeso.
5VB: Gululi ndi la zida zoonda kwambiri, zomwe zimakhala zosakwana 0.8 mm, zomwe zimazimitsa mkati mwa masekondi 60 ndipo sizimatulutsa kuyaka koyaka kapena kowala kupitilira chithunzicho.
Njira Zoyesera: Muyezo wa UL94 umagwiritsa ntchito njira zosiyanasiyana zoyesera kuti zitsimikizire kuti mapulasitiki akubwezanso malawi.Mayesowa akuphatikizapo Vertical Burning Test (UL94 VTM-0, VTM-1, ndi VTM-2), Horizontal Burning Test (UL94 HB), ndi 5V Burning Test (UL94 5VB).Chiyeso chilichonse chimawunika kuthekera kwa zinthuzo kuzimitsa zokha komanso kuthekera kwake pakufalitsa lawi.
Zolinga Zazida: Poyesa UL94, zinthu zingapo zimatha kukhudza mphamvu ya chinthu choyaka moto.Izi zikuphatikizapo makulidwe a chitsanzo, kukhalapo kwa zothandizira zakunja, zowonjezera, ndi utomoni womwe umagwiritsidwa ntchito.
Mapulogalamu ndi Mapindu: Kumvetsetsa UL94 zizindikiro zowotcha moto zimathandiza opanga kusankha zipangizo zapulasitiki zoyenera zogwiritsira ntchito zosiyanasiyana zomwe chitetezo chamoto chimakhala chofunika kwambiri.Zida zamagalimoto, zotchingira zamagetsi, zamagetsi ogula, ndi zida zomangira ndi zitsanzo zamafakitale ndi zinthu zomwe kutsata miyezo ya UL94 ndikofunikira.Kugwiritsa ntchito zida zokhala ndi magulu apamwamba a UL94 kumatsimikizira kulimba kwa moto komanso chitetezo.
Kutsiliza: UL94 flame retardant rating system ndi chida chofunikira pakuwunika mawonekedwe achitetezo pamoto wa zida zapulasitiki.Poyika mapulasitiki m'magulu osiyanasiyana monga V-0, V-1, V-2, HB, ndi 5VB, muyezo wa UL94 umathandizira opanga kumvetsetsa momwe zidazi zimakhalira pamoto.Kutsatira zida zokhazikika za UL94 pakupanga zinthu zotetezeka ndikuwonetsetsa kuti mapulasitiki omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana amakwaniritsa zofunikira zachitetezo chamoto.
Malingaliro a kampani Shifang Taifeng New Flame Retardant Co., Ltdndi katswirichoziziritsa moto chopanda halogenfakitale ku China ndi zaka 22 zinachitikira.
Mtengo wa TF-241ndi kuphatikiza APP flame retardant yomwe ingagwiritsidwe ntchito pa PP/HDPE.Zida za FR zitha kufika ku UL94 V0.
