Laser machining and welding process which produces harmful gases?
1, the laser machining process, depending on the work material, produces oxide, NO, NO2, CO, cobalt, chromium, nickel and other harmful gases and substances; 2, during welding, flux activation smoke contains HOC6H4COON phenol (C5H5OH), hydrochloric acid (HCL) and other toxic and harmful gases, while including CO, CO2, SO2, H2S, lead and fluoride fumes; 3, PCB board chemical cleaning, three anti-coating, coated hot eradicate other chemical treatment, will produce some of the irritating and harmful gases; 4, hot wire stripping process, many insulation materials will produce toxic and harmful gases; · Harmful gases which harm the human body?
Operator over a long time in environmental work, excessive inhalation of toxic substances will cause headaches, nausea, asthma, chronic bronchitis and other symptoms seriously affect health, but also affect the normal production; ·Why smoke purification system is very important for the company ?
1, to reduce operator complaints about the work environment ; 2 , reducing the operator to the company due to health reasons losses ( illness ) ; 3, to reduce losses due to downtime ; 4 , reducing wear and tear on the machine soot and products ; 5 , to meet the environmental and health aspects related to legal and regulatory requirements ; 6 , improve corporate image, promote corporate philosophy ; · Relevant laws and regulations : COSHH - UK / Europe Harmful to the control of goods - Europe NIOSH - USA National Institute for Occupational Safety and Health - United States OSHA - USA Occupational Safety and Health Regulations - United States AIHA - USA American Industrial Hygiene Association - USA Why choose smoke purification system During the welding process , will generate a lot of smoke , and 95% from the smoke generated by the solder particles , and 5% in the solder flux is produced harmful volatile gases . Also in cleaning, painting and other work environments will produce large amounts of harmful gases. And these pollutants on the operator and the environment will cause great harm. In Europe , the protection of workers welding and protection of the environment has been enforced in the form of legislation , in the absence of protective measures how welding conditions is not allowed . In the ISO14000 standard for pollution generated by production processes for processing and protection are clearly defined . How is welding fumes purification There are typically 95% at a high temperature solder and flux of volatile particles in welding fumes , particles floating in the air at a certain human eye to light can be observed , which we can see the smoke. The other 5% of the gas is distributed in the air way , we can not see the eye , which contains large amounts of carbon monoxide gas , carbon dioxide , methanol , ethanol , methane, formaldehyde and other harmful ingredients. These particles |
