Zingwe Zowotcha Moto

Zingwe Zowotcha Moto

Zingwe zosagwira moto ndi zingwe zopangidwa mwapadera zokhala ndi zida komanso zomangira zomwe zimakongoletsedwa kuti zipewe kufalikira kwa malawi moto ukayaka. Zingwezi zimalepheretsa lawi lamoto kufalikira motsatira utali wa chingwecho ndipo zimachepetsa kutulutsa utsi ndi mpweya wapoizoni pakayaka moto. Amagwiritsidwa ntchito kwambiri m'malo omwe chitetezo chamoto chimakhala chofunikira, monga nyumba zapagulu, zoyendera, ndi mafakitale.

Mitundu Yazida Zomwe Zimagwira Pazingwe Zowotcha Moto

Zigawo zakunja ndi zamkati za polima ndizofunikira pamayesero oletsa moto, koma kapangidwe ka chingwe ndi chinthu chofunikira kwambiri. Chingwe chopangidwa bwino, chogwiritsa ntchito zida zoyenera zoletsa moto, zimatha kukwaniritsa zomwe mukufuna.

Ma polima omwe amagwiritsidwa ntchito kwambiri poletsa moto amaphatikizansoZithunzi za PVCndiMtengo wa LSZH. Onsewa amapangidwa mwapadera ndi zowonjezera zoletsa moto kuti zikwaniritse zofunikira zachitetezo chamoto.

Mayesero Ofunika Kwambiri Pazinthu Zowonongeka ndi Flame Retardant ndi Kukulitsa Chingwe

Limiting Oxygen Index (LOI): Mayesowa amayesa kuchuluka kwa okosijeni wosakanizidwa ndi mpweya ndi nayitrogeni zomwe zimathandizira kuyaka kwa zinthu, zomwe zimafotokozedwa ngati peresenti. Zida zokhala ndi LOI yotsika kuposa 21% zimayikidwa ngati zoyaka, pomwe zomwe zili ndi LOI yopitilira 21% zimayikidwa ngati zozimitsa zokha. Mayesowa amapereka chidziwitso chachangu komanso choyambirira cha kuyaka. Miyezo yogwira ntchito ndi ASTMD 2863 kapena ISO 4589

Cone Calorimeter: Chipangizochi chimagwiritsidwa ntchito kulosera za nthawi yeniyeni ya moto ndipo chimatha kudziwa magawo monga nthawi yoyatsira, kutentha kwa kutentha, kutayika kwakukulu, kutulutsa utsi, ndi zinthu zina zogwirizana ndi mawonekedwe amoto. Miyezo yayikulu yogwiritsidwa ntchito ndi ASTM E1354 ndi ISO 5660, Cone calorimeter imapereka zotsatira zodalirika.

Mayeso otulutsa mpweya wa Acid (IEC 60754-1). Mayesowa amayesa kuchuluka kwa mpweya wa halogen acid mu zingwe, kudziwa kuchuluka kwa halogen yomwe imatulutsidwa pakuyaka.

Mayeso a Gasi Corrositvity (IEC 60754-2). Mayesowa amayesa pH ndi ma conductivity a zinthu zowononga

Kuyesa kachulukidwe ka utsi kapena kuyesa kwa 3m3 (IEC 61034-2). Mayesowa amayesa kuchuluka kwa utsi wopangidwa ndi zingwe zomwe zimayaka pamikhalidwe yodziwika. Mayesowa amachitikira m'chipinda chokhala ndi miyeso ya 3 metres ndi 3 metres ndi 3 metres (chomwe chimatchedwa 3m³ test) ndipo chimaphatikizapo kuyang'anira kuchepetsa kufalikira kwa kuwala kudzera mu utsi wopangidwa panthawi yoyaka.

Kuchuluka kwa utsi (SDR) (ASTMD 2843). Mayesowa amayesa kuchuluka kwa utsi wopangidwa ndi kuyaka kapena kuwola kwa mapulasitiki molamulidwa. Kuyesa kwachitsanzo 25 mm x 25 mm x 6 mm
