PCB equipment recycling
------------------------------
Currently in the world refuse to deal with such electronic equipment is not yet perfect, we After lengthy investigations research trials developed a more ideal processing equipment and recovery processes, and in Guangdong, Taiwan, Japan and other places have applied.
SBM produced circuit boards used recycling equipment is physical and chemical methods to metallic and non-metallic separation. Other large number of epoxy resin, phenol-formaldehyde resin, glass fiber can be re-processed into floor tile, decorative materials, insulating materials and furniture.
Major equipment include: breakers, shredders, separation, grinding mill machine, analyzer, air conveyor, hopper, feeder, precipitators, separators, closed wind, material storage room.
In the printed circuit board (PCB) production, and Crop Association have scrapped frame, such as a garbage disposal, the environmental impact will be. Waste board computer, television panels, boards, the cell phone equipment are more desirable for recycling equipment.
Six of the equipment has advantages:
Noise Without water No dust pollution High metal recovery Saving power, saving manpower No waste, metal and non-metallic full recovery of 97%.
I developed the circuit boards recovery equipment to smash through secondary machinery, metals and PCB board as non-metallic powder mixed, and through the air separation technology, or electrostatic separation technology, metal and non-metallic powder completely separated and collected. Production of dust produced during the adsorption of carbon dust can be closed or Central Room dust, or simply dust bag, the entire process in the realization of a production line, all closed operation, production will not create any pollution. Recovery of copper and glass fiber can be recycled.
Equipment package users based on actual choose different configurations.
Abstract: This paper reviews the PCB waste recycling equipment feasibility
First, the status quo electronic waste pollution
As electronic products updating speed, the e-waste generated faster speed. The United States is the world's largest producer of electronic products and the manufacture of electronic waste, e-waste generated each year of 7-8 million tons, and is becoming more and more of the next few years just to eliminate the old on the computer about 3 million units. Europe as a whole the volume of e-waste generated is about 6 million tons / year, of which Germany each year to produce 1.8 million tons of electronic waste, France is 1.5 million tons.
And in the country, with the rapid development of high-tech industries and the people's living standards rapidly improved, office, living in the use of computers, mobile phones, printers, and other electronic products to increase at an alarming rate. They scrapped after the e-waste poses a serious environmental pollution.
According to statistics, in 1991 China's mobile phone users to 1 million, in 2001 to more than 100 million, is expected in 2008 will reach 500 million. To the use of mobile phones on average every three years, China will be spent each year there are 70 million mobile phone number, plus phone annex and battery, the e-waste generated in about 400,000 tons. TV, washing machines, refrigerators, computers, and every year in the elimination of more than 20 million units, of which more than 400 million TV sets, washing machines more than 500 million units, refrigerators more than 500 million units, more than 600 million computers.
Second, e-waste hazards
Electronic improper waste disposal, a very big impact on the environment.
Waste electronic products and general MSW were very different: chassis plastic and circuit board containing brominated flame retardants; monitors, tubes and printed circuit boards, containing lead; circuit board solder pewter; semiconductors, circuit boards and batteries containing cadmium and iron chassis, disk drives containing chromium; switches, disk drives and sensors contain mercury; batteries containing nickel, lithium, cadmium and other metals; wire and packaging materials containing poly vinyl chloride, and so on.
E-waste in these substances are harmful. If the waste disposed of electronic products to the wilderness or no treatment landfill in the soil, will be the lead contained by the infiltration of soil and groundwater pollution. If these goods Waste incineration, and will release a large number of harmful gases, air pollution.
Third, e-waste pollution prevention and control measures
1, stacking storage
At present China has a large number of obsolete the old household appliances, electronic products stored in scattered families, factories, offices, although no longer in use, but has not discarded. Sometimes, through donations and other means to transfer elsewhere, can be re-used.
But these are just a short-term extension of the life of a little electronic products, and not the final solution. China marked the peak of scrapped household appliances, if not promptly disposed of, one day, the mountain of waste appliances.
2, the recycling of electronic waste
Is a rich e-waste. Waste electrical contains large amounts recoverable nonferrous metals, and ferrous metals, plastics, glass, as well as some parts are still useful, recycling has broad prospects. PCB waste above the electronic components can be removed with PCB waste can be developed through my company recovery circuit board handling equipment. With the promotion of equipment, electronic waste and natural resources can be as important as the "City of Mine."
