The treatment process is thorough in copper, mercury, selenium, lead, gold and silver separating effect, the gold, silver and selenium arebasically and completely enriched in the slag phase, the copper recycling rate is about 96%, the leaching rate of mercury is above 90%, and the aim of comprehensively treating valuable elements is achieved.

The invention relates to a production process of a freon resistant, double glass fiber covered enamelled wire, which solves problems of lag in an existing production process of glass fiber covered enamelled wires, large waste of raw materials, high energy consumption, environmental pollution and quality instability. The production process ensures quality of finished products and work efficiency by the following steps: strictly selecting the raw materials, taking the raw materials into a softening furnace for solidifying treatment by freon resistant insulating impregnating varnish; covering with conductor glass fiber, wherein, two layers of the glass fiber are covered in reverse directions to prevent single cladding; and controlling temperature of a baking furnace and the like. The production process has rational design, simple process, low manufacturing cost, low operating cost, reliable work, high efficiency, stable quality and strong workability, can help manufacture a plurality of different single and double glass fiber, paper covered and enamelled flat copper wires, round copper wires and irregular copper wires, and various electromagnetic wires for different uses, and the production process has wide market prospect.

The invention discloses a method of preparing a nano fire retardant coating by using wastes. The method is characterized by comprising the following technical steps: (1) selecting the following raw materials in percentage by weight: 65% of polystyrene foam, phenolic foam plastic, waste rubber and nitryl fibers, 15% of industrial alcohol, coal tar, acetone and a hydrosolvent, 15% of pigments and fillers, and 5% of a wetting dispersing agent, a defoamer, a delustering agent and a plasticizer assistant; (2) melting and extracting; (3) pre-extracting; (4) dispersing; (5) reconciling and modulating colors; (6) filtering; and (7) packaging. The method provided by the invention is reasonable and concise in process, the process flow is greatly shortened, the raw material of the coating is wide in source, and the method belongs to waste recycle, so that the production cost is lowered. Meanwhile, coatings with various functions are conveniently prepared according to raw material ratio, so that the method is applicable to demand of production process. The inventory rating and proportioning are accurate with less inventory rating, the product quality is ensured, and the yield of enterprises is effectively improved.
