Mu dziko la mapulasitiki, kuonetsetsa kuti chitetezo cha moto n'chofunika kwambiri. Pofuna kuwona momwe zinthu zosiyanasiyana zapulasitiki zimagwirira ntchito, a Underwriters Laboratories (UL) adapanga muyezo wa UL94. Dongosolo lodziwika bwino limeneli limathandiza kudziwa momwe mapulasitiki amayakira komanso limathandiza opanga kupanga zinthu zotetezeka.
Magulu a UL94: Muyezo wa UL94 umagawa zinthu zapulasitiki m'magulu osiyanasiyana kutengera momwe zimakhalira panthawi yoyesa moto. Pali magulu asanu akuluakulu: V-0, V-1, V-2, HB, ndi 5VB.
V-0: Zipangizo zomwe zimadutsa gulu la V-0 zimazimitsa zokha mkati mwa masekondi 10 mutachotsa gwero la kuyatsa ndipo sizipanga kuyaka koyaka kapena kowala kupitirira chitsanzocho.
V-1: Zipangizo zomwe zimadutsa gulu la V-1 zimazimitsa zokha mkati mwa masekondi 30 ndipo sizipanga kuyaka koyaka kapena kowala kupitirira chitsanzocho.
V-2: Zipangizo zomwe zimayikidwa mu V-2 zimazimitsa zokha mkati mwa masekondi 30 koma zimakhala ndi kuyaka pang'ono kapena kuyaka moto pambuyo poti lawi lachotsedwa.
HB: Kugawa kwa kutentha kopingasa (HB) kumagwira ntchito pazinthu zomwe sizikukwaniritsa zofunikira za magulu oyima koma sizimafalitsa lawi kudutsa chitsanzocho panthawi yoyesa.
5VB: Gulu ili ndi la zipangizo zoonda kwambiri, zomwe nthawi zambiri zimakhala zosakwana 0.8 mm, zomwe zimazimitsa zokha mkati mwa masekondi 60 ndipo sizipanga kuyaka kapena kuyaka kupitirira chitsanzocho.
Njira Zoyesera: Muyezo wa UL94 umagwiritsa ntchito njira zosiyanasiyana zoyesera kuti udziwe kuchuluka kwa mapulasitiki omwe amaletsa moto. Mayesowa akuphatikizapo Vertical Burning Test (UL94 VTM-0, VTM-1, ndi VTM-2), Horizontal Burning Test (UL94 HB), ndi 5V Burning Test (UL94 5VB). Mayeso aliwonse amayesa kuthekera kwa chipangizocho kudzimitsa chokha komanso kuthekera kwake kofalitsa moto.
Zofunika Kuganizira: Mukamayesa UL94, zinthu zingapo zimatha kukhudza kuchuluka kwa zinthu zomwe zimaletsa moto. Izi zikuphatikizapo makulidwe a chitsanzocho, kupezeka kwa zothandizira zakunja, zowonjezera, ndi utomoni womwe umagwiritsidwa ntchito.
Kugwiritsa Ntchito ndi Ubwino: Kumvetsetsa ziwerengero za UL94 zoletsa moto kumathandiza opanga kusankha zipangizo zoyenera zapulasitiki zogwiritsidwa ntchito zosiyanasiyana komwe chitetezo cha moto chili chofunika kwambiri. Zigawo zamagalimoto, zotchingira zamagetsi, zamagetsi zamagetsi, ndi zipangizo zomangira ndi zitsanzo za mafakitale ndi zinthu zomwe kutsatira miyezo ya UL94 ndikofunikira. Kugwiritsa ntchito zipangizo zomwe zili ndi magulu apamwamba a UL94 kumatsimikizira kuti pali kukana moto komanso chitetezo.
Pomaliza: Dongosolo lowunikira la UL94 loletsa moto ndi chida chofunikira kwambiri poyesa mawonekedwe a chitetezo cha moto cha zipangizo zapulasitiki. Mwa kugawa mapulasitiki m'magulu osiyanasiyana monga V-0, V-1, V-2, HB, ndi 5VB, muyezo wa UL94 umathandiza opanga kumvetsetsa momwe zipangizozo zimachitira akamakumana ndi moto. Kutsatira muyezo wa UL94 kumathandiza popanga zinthu zotetezeka ndikuwonetsetsa kuti mapulasitiki omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana akukwaniritsa zofunikira zofunika pachitetezo cha moto.
Malingaliro a kampani Shifang Taifeng New Flame Retardant Co., Ltdndi katswiricholetsa moto chopanda halogenfakitale ku China yokhala ndi zaka 22 zakuchitikira.
TF-241ndi APP yosakaniza yoletsa moto yomwe ingagwiritsidwe ntchito pa PP/HDPE. Zipangizo za FR zimatha kufika UL94 V0.
