August to September period, Wenzhou Low Voltage Electrical Apparatus Laboratory successfully completed the third phase of the life of 13 test port control circuit debugging work, together with the short circuit test before the completion of each port debugging, the laboratory's core short-circuit system and electrical life System control circuit has been fully debugged. Before May, the laboratory had verified the short-circuit ports by the low-voltage method and evaluated the impedance and acquisition system of the circuit. The results showed that the system met the design requirements under low-voltage conditions. At this point, Wenzhou Low Voltage Electrical Laboratory Phase III project already has a full voltage power-on test conditions. (Ruian Office Wang Jianxin)
Nylon 610 Filament
An approximate of 60% of PA610 Brush Filament is made of sustainable plant-based materials. While its performance is very similar to PA612, PA610 Brush Bristle has great resistance to scratch, low temperature properties and water absorption. It also has great chemical stability as it has great resistance to weak base and weak acid. It is recommended for producing high-end brush products, such as toothbrushes, Makeup Brush Filament, nail polish brush and other cleaning brush etc. Nylon 610 Filament,Nail Polish Brush Filament,Soft Cosmetic Brush Filament,Facial Brush Filament Tai Hing Nylon Filament Products Co.,Ltd , https://www.brushfibres.com
