Different grades are mainly distinguished by burning time, dripping and burning through: Extinguishing time: V-0 requires that the fire source be extinguished quickly within 10 seconds after being removed, and V-1 and V-2 are allowed to be extinguished within 30 seconds. Drops: V-0 and V-1 are not... READ MORE
The fire protection grade of ABS is mainly divided according to UL94 standard, and it is divided into six main grades: HB, V-2, V-1, V-0, 5VB and 5VA from low to high. Among them, V-0 is a high flame retardant grade commonly used in electronic and electrical industries, and 5VA is the grade. all ... READ MORE
The galvanized sheet itself has good moisture-proof and corrosion-proof performance. The zinc layer on its surface can effectively prevent water vapor from eroding the steel base through physical isolation and electrochemical protection mechanism of "sacrificial anode", and it will not get moldy and...
