In the current era of rapid digitalization, the speed of electronic equipment replacement is amazing. According to authoritative data, the number of waste printed circuit boards added worldwide each year is as high as 50 million tons, and it continues to rise at a rate of 5%-8% per year. These waste printed circuit boards are like "time bombs" hidden in the environment, rich in heavy metals such as lead, mercury, cadmium, and harmful substances such as brominated flame retardants. Once the disposal is slightly wrong, these harmful substances will be washed away by rainwater and infiltrated into the soil and groundwater, causing immeasurable and long-term serious damage to the ecological environment. Scientific research shows that the heavy metals contained in only 1 ton of waste printed circuit boards that have not been properly treated can pollute more than 1 million cubic meters of groundwater, causing the scope of soil pollution to spread to several square kilometers, and the impact of pollution will last for decades or even hundreds of years. Not only that, these harmful substances will continue to accumulate through the food chain, posing a serious threat to the human nervous system, immune system and other key physiological systems, greatly damaging human health.
In this severe environmental situation, the recycling and reuse of waste printed circuit boards is particularly urgent and far-reaching. Recycling and converting them into other practical materials can not only significantly reduce the pollution load of waste on the environment, but also effectively promote the recycling of resources, effectively reduce excessive dependence on primary resources, and greatly alleviate the huge pressure brought by resource shortages. As a new type of environmentally friendly material with excellent performance, wood-plastic materials have become the only choice for the recycling and reuse of waste printed circuit boards with their good physical properties and outstanding environmental characteristics.
Yongte, as a leader in the field of wood-plastic flooring production equipment in China, its carefully developed wood-plastic flooring production equipment provides solid and reliable technical guarantees for the preparation of wood-plastic materials from waste printed circuit boards. The equipment has successfully passed the CE certification and can be customized for customers to cover the entire process from raw material processing to finished product processing.
From the production process point of view, the equipment fully demonstrates the efficient use of waste resources in the raw material preparation link. The plastic recycling machine can accurately process 300 kg of plastic waste such as PP and PE per hour, converting it into plastic sheets required for wood-plastic products. The whole process goes through a series of fine processes such as crushing, cleaning, and drying, and the plastic recycling rate is as high as over 95%. The wood powder making machine can stably produce 400-600 kg of 80-120 mesh wood powder per hour, showing strong adaptability to all kinds of wood raw materials. Entering the WPC pellet production stage, the WPC granulator has an hourly production capacity of 400-500 kg. Through a unique process, it ensures that wood and plastic are fully integrated, so that the tensile strength of the final product is increased by 20%-30%. In the final WPC product extrusion molding stage, the WPC profile co-extruder has an hourly extrusion capacity of 150-200 kg. It can produce more than 20 profiles of different sizes and shapes by flexibly changing molds, and is equipped with advanced online embossing machines, sanding machines, wire drawing machines and other equipment to give the product a realistic wooden appearance and delicate touch.
Take the equipment of model SJSZ65/132 as an example, its technical parameters are excellent. The plastic recycling machine can easily process more than 6 common plastic wastes including ABS, PVC, etc., and the wood powder making machine can adapt to the moisture content of raw materials in the range of 5% - 20%. The WPC mixer can accurately mix 600 kg of raw materials per hour, and the wood content can be flexibly adjusted in the range of 60% - 70%, with an error control within ±2%.
It is worth noting that in terms of cost control, the use of waste printed circuit boards to prepare wood-plastic materials also has significant advantages. Its costs mainly cover raw materials, equipment investment and depreciation, production and other expenses. In terms of raw material costs, the non-metallic part of waste printed circuit boards after pretreatment can account for 10% - 40%, which can effectively reduce the overall raw material cost by 15% - 30%. From the perspective of scale benefits, the comprehensive cost is about 6,000-8,000 yuan/ton for small-scale production (annual output of 500-1,000 tons); for medium- and large-scale production (annual output of more than 5,000 tons), the cost can be greatly reduced to 4,000-6,000 yuan/ton, which is 10%-20% lower than the cost of traditional wood-plastic material preparation.
Yongte wood-plastic flooring production equipment plays an irreplaceable key role in the field of preparing wood-plastic materials from waste printed circuit boards with its outstanding advantages such as high efficiency, environmental protection, and easy operation. It not only opens up a practical and innovative path for the resource utilization of waste printed circuit boards, and strongly promotes the vigorous development of environmental protection, but also shows extremely broad application prospects in many fields such as construction, furniture, and gardening. According to market authority forecasts, in the next five years, the scale of the waste printed circuit board recycling and reuse industry driven by such equipment will exceed 100 billion yuan, which is expected to lead the new trend of industry development and inject new economic growth points and sustainable development momentum into related industries.
