currently, many varieties of wire on the market, specifications, price chaos, when consumers choose a lot of difficulty. general household decoration, commonly used 2.5 mm and 4 mm square two copper wire, but the price, the same specifications as a line, because of different manufacturers, the price can vary from 20% to 30%. as for the quality, length is required, consumers are difficult to determine.

according to industry sources, the reason why the price difference is huge, due to the production process of raw materials used in different. the main raw materials for the production of wire are electrolytic copper, insulation and sheath material. at present, the raw material market in more than 70 thousand yuan per ton of electrolytic copper, and copper recovery is a lot cheaper; insulation and sheath material of high quality products and defective products more price disparity. in addition, the length is not enough, the amount of the insulator is not enough, but also an important reason for price differences. each line length is 100 meters, excellent products, and products is only about 90 meters; insulator guttacontent high-class products accounted for 35% to 40%, while the defective products only 15%. by contrast, the consumer is not difficult to see, the difference is the sales price of finished wire material caused by tricky.

so, how to identify the pros and cons of the purchase of wire?

i look to see whether the quality system certification certificate; see is standard; see no name and address, chapter inspection and production date; see the wire is printed trademark, specifications, voltage etc.. depends on the cross-section copper wire, copper products excellence in bright colors, soft colors, or is defective.

two to try, it is desirable to use a wire to bend the hands repeatedly, usually soft, good anti fatigue strength, plastic or rubber handle elastic and no cracks on the wire insulator is the best. look at the material

in order to make the room beautiful, people in the decoration, water pipes are generally used in the construction of the wall, so if the water quality is not good, once the leakage and burst, will bring irreparable consequences.

aluminum plastic composite pipe is a pipe more popular on the market, its lightweight, durable and convenient construction, its flexibility is more suitable for use in the home. the main disadvantage is used in hot water use, because of the long-term expansion and contraction may cause sleeve type connecting displacement to cause leakage. buy plastic composite pipe, need to pay attention to two points: 1. check the appearance of the product, good quality plastic composite pipe, usually on the wall of the tube wall smooth, trademark, specifications, suitable temperature, the number of meters clearly marked on the pipe wall manufacturers also print production numbers, and shoddy products like a rough wall, the label is not clear or not, packaging simple, site or unknown phone. look at the layer of aluminum plastic composite pipe, well, in the aluminum layer lap welding, aluminum layer and the plastic layer tightly, no delamination, and shoddy products are not.
