Selection of wire, seemingly simple, but in fact is closely related to family life and property safety, therefore, must be cautious. If you have professional qualifications, it is best to use technical means. If not, you should pay attention to the following points: Look at the manufacturer. Different manufacturers, in the production equipment, product quality and business philosophy, there will always be such a difference. In general, the regular manufacturing enterprises approved by the state have not only good protection in production facilities, production management and product quality, but also the strict checks of the relevant departments in the area of ​​product quality inspection and examination. Buy these manufacturers products, the quality will be guaranteed. It is obviously not possible to have these conditions rather than the products produced by the regular manufacturers. As fake and shoddy products, poor quality does not say that once a problem, even claims can not find the door. Therefore, the purchase of wire, be sure to buy regular manufacturers of products, this must be unambiguous. Look at the product label. Regular, qualified wire, usually affixed with the relevant 3C certification, the name of the manufacturer, wire specifications and other content, and the use of high-quality inkjet printing or laser printing. Informal products on the body is marked simple, some even without labeling. Jet printing logo is also prone to fall. In addition, the qualified product is shipped with a factory-made certificate for each wire, which has details about the manufacturer and the wire, but no or no such content on the wire. On the one hand, these data are one of the methods for judging the authenticity of the electric wire. On the one hand, they are also the safeguard for the consumers to deal with the problems in the future. See production date. In the ideal environment, the shelf life of wires can generally reach about 20 years. However, if the long-term placement in the hotter, pH environment, this time will be greatly reduced. Therefore, when the wire is purchased, the production date of the wire is also an important reference. Regular wire will be marked with production time, at the time of purchase, consumers can try to choose the production date of the product, to avoid loss of quality of the wire during storage. See product specifications. As more types of wire models, different types of wires have different best working environment. Therefore, in the selection of wire, be sure to understand their own requirements on the wire, and then purchase the appropriate type of wire on request. For example, when used in some high-voltage motors, it is necessary to clearly understand the operating voltage range of the electric wire when selecting the electric wire and to avoid the problems of over-loss under high load and the like. See sales channels and procedures. Whether it is direct sales or agency, regular wire distributors have manufacturers issued the relevant certificates, sales certificates and other basic materials. Informal vendors, however, lack relevant material. Therefore, consumers in the purchase of wire, it is best to require vendors to produce sales certificates, proof of agency, to avoid losing fooled. Use direct contact method. In addition to the above methods, the conditions of the case, you can also take "a look, a break, a burning" direct contact method to judge the quality of the wire. The so-called first look, refers to the purchase of wire can be observed by cross-section of the quality of the exposed copper core to determine the product is good or bad. Qualified copper core should be purple, shiny, feel soft; and fake and shoddy products are often purple and black copper, yellow and more impurities. The so-called one-off, is that consumers can choose a wire head to take repeated bending method to detect the quality of the wire. Qualified wire will appear in the bending of the plastic or rubber packaging feel flexible, soft, good fatigue strength, repeated bending, the wire insulation surface material no change, no crack. Informal products may appear in the process of cracks in the surface of the insulator, and even broken copper core. A burn, it means that consumers can use the lighter for a simple combustion test. Regular wires are designed with heat and fire resistance in mind, so when burning, surface insulators burn more slowly and smoke is smaller or even smokeless. Some fire-resistant wire products, even with alcohol torches, can not ignite , And after the combustion heat faster; and for non-qualified wire, with a lighter roasted point is prone to rapid and coherent combustion, at the same time emit a large amount of smoke. In this way, we can more intuitively determine the quality of the wire level.
Nickel Based Laser
Cladding Powder
Ni base alloy
powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has
good wettability, corrosion resistance and high temperature self-lubricating
effect, and is used in components with heat resistance, corrosion resistance and
thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser
cladding, the No means hardness of powder. Inconel 625 and 718 has good
corrosion property under higher temperature, also widely used for laser
cladding process.
Cobalt based Laser
Cladding Powder
Cobalt-based alloy
powder is the cemented carbide resistant to various types of wear and corrosion
as well as high temperature oxidation. That is, the so-called
cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based
alloy is mainly composed of cobalt, containing a considerable amount of nickel,
chromium, tungsten and a small amount of molybdenum, niobium, tantalum,
titanium, Alloying elements such as lanthanum, and occasionally a class of
alloys containing iron.
Co-based self-fluxing
alloys have good high temperature performance and wear resistance and corrosion
resistance, and are used in petrochemical power, metallurgy and other
industrial fields where they are wear-resistant, corrosion-resistant and
high-temperature resistant.
Iron based Laser
Cladding Powder
The work pieces
required for laser cladding and manufacturing in the actual industry are mainly
carbon steel and cast steel. The Fe-based alloy is close to the base material
in composition and has good wettability. The advantage of Fe base powder is
lower cost and good wear resistant of cladding layer. As a result, it`s the
most widely used for laser cladding process. It is suitable for parts that
require local wear resistance and are easily deformed.
WC blended Laser
Cladding Powder
Tungsten carbide blended with Ni alloy powder is the best
choice for wear resistant work piece. This unique process can bring excellent
wear, corrosion and high temperature resistant. Our blend powder can achieve
different portion of WC from 35% to 60% without crack under suitable cladding
parameter.
