Copper alloy material for textile plant water treatment and preparation method thereof

Abstract

The invention discloses a copper alloy for textile plant water treatment and a preparation method and a treatment method thereof. The copper alloy comprises the following components by weight percent: 5-10% of aluminum, 4-8% of magnesium, 6-15% of titanium, 5-10% of nickel, 5-10% of iron, 0.01-0.1% of manganese, 0.01-0.15% of rare earth elements and the balance of copper and inevitable impurities. The preparation method mainly comprises the following working procedures: melting, performing primary refining, performing secondary refining, cooling and discharging and the like. The treatment method adopts the anodic oxidation or micro-arc oxidation treatment.

Description

technical field [0001] The invention relates to an alloy and a preparation method thereof, in particular to a copper alloy material for water treatment in textile mills and a preparation method thereof. Background technique [0002] The water used by textile enterprises includes washing water, dyeing water, boiler water, and heat exchange water. [0003] For washing water, the iron ions caused by the corrosion of the pipeline will cause the fibers to be brittle during the oxygen bleaching process, resulting in holes or pinholes, which will cause huge losses to the enterprise. At the same time, calcium and magnesium ions will also increase the difficulty of washing, resulting in The large increase in the amount of pre-treatment detergent will of course double the amount of builder phosphate. The use of a large number of surfactants and phosphate will also bring great pressure to sewage treatment, or spend huge sums of money on water treatment. Deionization treatment, but in ...

[0003] For washing water, the iron ions caused by the corrosion of the pipeline will cause the fibers to be brittle during the oxygen bleaching process, resulting in holes or pinholes, which will cause huge losses to the enterprise. At the same time, calcium and magnesium ions will also increase the difficulty of washing, resulting in The large increase in the amount of pre-treatment detergent will of course double the amount of builder phosphate. The use of a large number of surfactants and phosphate will also bring great pressure to sewage treatment, or spend huge sums of money on water treatment. Deionization treatment, but in the process of pipeline transportation of deionized water, a large amount of iron ions will be introduced due to pipeline corrosion, and it is inevitable to use chelating dispersants; a medium-sized printing and dyeing factory with a monthly output of 10 million meters of pure cotton cloth only chelates The cost of compounding and dispersing agent is about 6 million yuan. The increase in the amount of detergent and the decrease in washing speed will greatly increase the consumption of water, electricity and steam in the enterprise, and also increase the burden of sewage treatment. For dyeing water, due to the prevention of The water contains a lot of calcium, magnesium or iron plasma, resulting in dyeing failure, which forces enterprises to use a large amount of chelating agent

[0004] For boiler water and heat exchange water, the boiler water of textile enterprises is the same as that of other industrial boilers, and because of its particularity, it is easy to cause auxiliary obstacles to the printing and dyeing industry, especially the scaling and corrosion of heat exchange equipment is serious, and the equipment is heavy and difficult to maintain and repair. move

[0005] When the copper alloy of the prior art is applied to the dye industry, it more or less affects the anhydrous treatment of printing and dyeing, environmental protection, and cannot further enhance the effect of pipeline corrosion, and the copper alloy in the water treatment equipment in the prior art There is no report on the special composition selection and surface treatment of heat exchange materials, which directly affect the further use of water treatment equipment and its alloys in detail, and seriously restrict the progress of the textile industry and the performance improvement of products.
