Weifang electric protective doors, Shield protection (certified), electric protective doors

 Lead is a gray metal medical electric protective doors, the density of 11.34, melting point 327.5 ℃ Weifang electric protective doors, boiling point 1740 ℃, soft, small tensile strength. Lead by oxygen, water and carbon dioxide effects electric protective doors in the air, it will soon be oxidized surface protection film; in the heating, can quickly lead to oxygen, sulfur, halogen compounds; lead and almost cold hydrochloric acid, sulfuric acid is not cold work, with hot or concentrated hydrochloric acid, sulfuric acid reaction; lead and dilute nitric acid reaction, but does not react with concentrated nitric acid; Lead can slowly dissolve in strong alkaline solution. Lead and its compounds have greater toxicity to humans, and can accumulate in the human body. Hose type explosion wave valve hose type valve is a new wave explosion-proof equipment developed in the 1980s, which is based on a flexible hose made of rubber material as the main valve explosion wave valve. Products with KJH said ventilation rate from 900m3 / h -22600m3 / h can be used. Closed valve is installed in the ventilation duct flexible opening and closing of a closed device. Normal ventilation to protect the open, closed airtight isolation can do. It can be divided into two kinds of manual and electric. Auto exhaust valves, exhaust valves explosion overpressure basement wartime machinery usually into the wind, overpressure exhaust ventilation mode. Auto exhaust valve is a device for overpressure ventilation exhaust. Explosion wave overpressure exhaust valve can be mounted directly on the wall in the monitoring, both to protect wartime overpressure ventilation, but also the ability to have proof waves.
