PECOAT® PVC kuyanika Kukumana ndi Flame Retardant UL94 V0

Kuyesa kwa Flame Retardant UL94 V0

Malinga ndi lipoti la mayeso loperekedwa ndi bungwe loyesa padziko lonse lapansi la SGS, PECOAT® PVC ❖ kuyanika wakumana ndi mulingo wa UL94 V0 pamayeso oyeserera amoto.

Chiyesochi chinayang'ana pa 50W (20mm) yowotcha yowotcha ntchito yowonongeka, yomwe imachitika motsatira ndondomeko ya UL 94-2023 Rev.2-2024 Gawo 8. Zitsanzo zoyesedwa zinali A-mapepala okhala ndi 125mm × 13.0mm × 5.3mm. Kuyesedwa kunachitika pansi pazikhalidwe ziwiri, zomwe ndi "boma lolandilidwa" (loyikidwa m'malo okhala ndi kutentha kwa 23 ± 2 ℃ ndi chinyezi chachibale cha 50 ± 5% kwa 48h) ndi "pambuyo pa ukalamba" (wokalamba m'malo a 70 ± 2 ℃ kwa 168h, kenako amayikidwa mu 23 ± 2 ℃ pa 4 ± XNUMXh). Zitsanzo zisanu zinayesedwa pansi pa chikhalidwe chilichonse.

Kuchokera pazotsatira zoyesa, pansi pazimenezi, nthawi yotsatila ya zitsanzo zonse pambuyo pa ntchito yoyamba ndi yachiwiri yamoto inali ≤10s, ndipo chiwerengero cha nthawi yamoto ndi nthawi yowunikira pambuyo pa ntchito yachiwiri yamoto inali ≤30s. Kuphatikiza apo, palibe chitsanzo chomwe chinawotchedwa mpaka ku chipangizo cholumikizira, ndipo panalibe vuto la tinthu tating'onoting'ono toyaka kapena madontho omwe amayatsa thonje. Pakati pawo, nthawi yonse ya afterflame ya zitsanzo zisanu pansi pa "boma lolandilidwa" inali 8.9s, ndipo pansi pa "pambuyo pa ukalamba" inali 12.4s, zonse zotsika kwambiri kuposa ≤50 zomwe zimafunidwa ndi mlingo wa V0. Kutengera deta yokwanira, kuyatsa koyima kwa zokutira kudavotera ngati mulingo wa V0.

Mulingo wa UL94 V0 ndi umodzi mwamiyezo yayikulu pakuchedwa kwamoto kwa mapulasitiki. PECOAT® PVC zokutira plastisol Kufika pamlingo uwu kukuwonetsa zinthu zake zabwino kwambiri zoletsa moto komanso kumapereka zitsimikizo zodalirika zachitetezo pazochitika zoyenera kugwiritsa ntchito.

Kufotokozera Mwatsatanetsatane UL94 V0 Flame Retardant Standard

UL94 ndi muyezo woyesera kuyaka kwa zida zapulasitiki zopangidwa ndi Underwriters Laboratories (UL). Pakati pawo, mulingo wa V0 ndi umodzi mwamagiredi apamwamba kwambiri oletsa moto pamlingo uwu, womwe uli ndi zofunika kwambiri pakuchita zinthu zoletsa moto.

Malinga ndi muyezo wa UL 94-2023 Rev.2-2024 Gawo 8 ndi zofananira zomwe zatchulidwa mu lipoti la mayeso, ziweruzo za mulingo wa UL94 V0 ndi motere:

• Nthawi ya afterflame (t1 ndi t2) ya chitsanzo chilichonse choyeserera pambuyo pa kugwiritsa ntchito moto koyamba ndi kwachiwiri idzakhala ≤ 10s.​
• Nthawi yonse ya afterflame (chiwerengero cha t1 ndi t2) ya zitsanzo zoyesedwa 5 mumagulu aliwonse azikhala ≤ 50s.​
• Chiwerengero cha nthawi yamoto wamoto ndi nthawi yowala (t2 + t3) ya chitsanzo chilichonse choyeserera pambuyo poyatsanso lawi lachiwiri chizikhala ≤ 30s.​
• Palibe mayeso omwe amaloledwa kuyaka mpaka pachipangizo cholumikizira
• Tinthu tating'onoting'ono toyaka kapena madontho saloledwa kuyatsa chizindikiro cha thonje pansipa

Miyezo imeneyi imayesa mokwanira mphamvu ya zinthu zomwe zimawotcha moto kuchokera ku miyeso ingapo monga nthawi yamoto, nthawi yowala, nthawi yoyaka ndi mphamvu ya zinthu zomwe zimayaka. Zida zomwe zimafika pa mlingo wa V0 zimatha kuzimitsa zokha mwamsanga zikakumana ndi lawi lotseguka, lokhala ndi chiopsezo chochepa cha kufalikira kwa moto, zomwe zingathe kuchepetsa zoopsa zamoto ndikukhala ndi zofunikira zogwiritsira ntchito m'minda yomwe ili ndi zofunika kwambiri pa ntchito yoletsa moto.
