It is a necessary basic product in an electrified and informationized society. With the rapid development of economic construction, the demand for insulated wire and cable in all walks of life is also increasing.
绝缘电线电缆一般包括导体、挤包在所述导体外的绝缘层以及挤包在所述绝缘层外的护套。现有的绝缘电线电缆，其上的绝缘层及护套多为聚氯乙烯(PVC)材料，这是由于聚氯乙烯具有优良的电气绝缘性能、抗化学性能、自熄性和循环利用性等优点，因此被广泛应用。An insulated wire and cable generally includes a conductor, an insulating layer extruded outside the conductor, and a sheath extruded outside the insulating layer. Existing insulated wires and cables, the insulation layer and sheath on it are mostly polyvinyl chloride (PVC) material, which is because PVC has excellent electrical insulation performance, chemical resistance, self-extinguishing and recycling properties, etc. advantages and are therefore widely used.

As a stabilizer, flame retardant, plasticizer, colorant, etc. As we all know, the above-mentioned heavy metals and polybrominated organic substances are cumulatively harmful to humans. They will damage the internal organs of the human body, including the kidneys, digestive system, nervous system and reproductive system, causing increased blood concentration, hemoglobin disorders, nausea, Vomiting, infertility, renal insufficiency, cancer and brain disease, etc.
当对陈旧老化的绝缘电线电缆进行处理(多采用焚烧或掩埋的方式)时，上述重金属、多溴有机物等有害物质会从绝缘电线电缆的绝缘层和护套中分解出来，进而污染土壤、水质、大气等，从而对环境造成严重危害；而且，这些有害物质直接威胁着人类的健康。When the old and aging insulated wires and cables are disposed of (by incineration or burial), the above-mentioned heavy metals, polybrominated organic substances and other harmful substances will be decomposed from the insulation layer and sheath of the insulated wires and cables, thereby polluting the soil and water quality , atmosphere, etc., thereby causing serious harm to the environment; moreover, these harmful substances directly threaten human health.
