　　Choosing which surface treatment to use is a problem that every designer faces. There are many types of surface treatments to choose from, and not only should the economy and practicality of the design be considered, but also the processability of the assembly and even environmental protection requirements should be taken into consideration. The following is a brief introduction to some commonly used coatings for fasteners based on the above principles for reference.In addition to innate advantages, Non standard hardware factory Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://jieruifasteners.com/

　　1. Electrogalvanizing

　　Electrogalvanizing is the most commonly used coating for commercial fasteners. It is relatively cheap and looks good. Common colors include black and military green. However, its anti-corrosion performance is average, and its anti-corrosion performance is the lowest among zinc plating (coating) layers. Generally, the neutral salt spray test of electrogalvanizing is within 72 hours. Special sealants are also used to make the neutral salt spray test reach more than 200 hours, but the price is expensive, which is 5 to 8 times that of general galvanizing. The torque-preload consistency of electrogalvanized fasteners is poor and unstable, and is generally not used for connections in important parts. In order to improve the torque-preload consistency, the method of applying lubricating substances after plating can also be used to improve and improve the torque-preload consistency.

　　2. Phosphating

　　A basic principle Phosphating is cheaper than galvanizing, but its corrosion resistance is worse than galvanizing. Oil should be applied after phosphating, and its corrosion resistance is greatly related to the performance of the oil applied. For example, after phosphating, applying general anti-rust oil, the neutral salt spray test is only 10 to 20 hours. Applying high-grade anti-rust oil can last for 72 to 96 hours. But its price is 2 to 3 times that of general phosphating oiling.

　　There are two common types of non-standard fasteners phosphating, zinc phosphating and manganese phosphating. Zinc phosphating has better lubrication performance than manganese phosphating, and manganese phosphating has better corrosion resistance and wear resistance than galvanizing. Its operating temperature can reach 225 degrees to 400 degrees Fahrenheit (107 to 204 degrees Celsius). Especially for the connection of some important parts. Such as the connecting rod bolts and nuts of the engine, cylinder heads, main bearings, flywheel bolts and wheel bolts and nuts. Phosphating high-strength bolts can also avoid hydrogen embrittlement problems, so in the industrial field, bolts above grade 10.9 are generally treated with phosphating surface treatment.

　　3. Oxidation blackening

　　Blackening + oiling is a very popular coating for industrial fasteners because it is the cheapest and looks good before the oil runs out. Since blackening has almost no anti-rust ability, it will rust quickly after oiling. Even in the presence of oil, the neutral salt spray test can only reach 3 to 5 hours.

　　4. Electroplating cadmium

　　Cadmium coating has good corrosion resistance, especially in marine atmospheric environment, its corrosion resistance is better than other surface treatments. The waste liquid treatment cost in the process of electroplating cadmium is high, and its price is about 15~20 times that of electroplating zinc. Therefore, it is not used in general industries and is only used in some specific environments. For example, it is used for non-standard fasteners for oil drilling platforms and HNA aircraft.

　　While the Olympic Games are in full swing in Paris, France, the U.S. presidential election has also become a hot topic of global attention. Since Trump got a higher approval rating than Biden in the assassination, there has been a “dark horse” on the road to the US presidential election. Harris, known as the “Black widow,” has become a strong opponent of Trump and has gained very high support rates in a very short period of time. European and American media said that Harris is expected to become the first female president of the United States.Before that, female bodyguard The market has also soared for a time, which has attracted the attention of a wide range of investors. http://huanyubodyguard.com/

　　The reason why Harris received a high vote support rate in the short term is that Harris openly supported women’s rights, supported illegal immigrant groups, and expressed love for women and children in the speech process. During Harris’ speech in the United States, his mental state was very full, and there were bodyguards around Harris for personal security protection.

　　The reason why Harris can become a strong opponent against Trump in a short period of time, and she is of Indian descent and black origin has a considerable relationship, plus Harris is a woman, easy to get the support of feminists around the world. In addition, what Harris supports is not the same as what Trump supports, so in the short term, Harris has shown a good advantage in the US presidential election. Harris, like some rich women in Shenzhen, China, is calm and confident, has a strong personality charm, and has a strong sense of safety and self-protection. The female rich in Shenzhen, China, will hire bodyguards from the Huanyu Brothers bodyguard company in Shenzhen, China, and Harris will bring elite bodyguards to the United States to give speeches and escort personal safety.

　　As for whether Harris can defeat Trump to become a female president in the history of the United States, it also depends on Harris’s late vote support rate and the public opinion of the American people, but Harris has now become a fierce enemy on Trump’s campaign road.

　　Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.If you want to make a big difference in the market, multicore cable price It is necessary to intensify the upgrading of products on the original basis in order to meet the consumption needs of consumers. https://www.linkcablecn.com

　　Is it better to have a multi-core cable or a single-core cable?

　　1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.

　　2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.

　　3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.

　　4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

　　The difference between single-core cables and multi-core cables

　　2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.

　　3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.

　　4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.

　　5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.

　　Multicore Flexible Cable supplier.jpg

　　The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.

　　Anti-loosening nut is a nut, which is a part that is screwed together with a bolt or a screw for tightening. It is an original part required by all production and processing equipment. Anti-loosening non standard nut is a part that tightly connects mechanical equipment together. With the help of the inner thread, anti-loosening nuts and screws of the same specifications can be connected together. The following is a detailed introduction to several methods of preventing anti-loosening nuts from slipping.for a long time non standard fasteners It has an extraordinary development speed, and I believe that the future will be as overwhelming as ever. https://jieruifasteners.com/

　　1. Anti-loosening of equipment

　　It is to use the locking nut stopper to directly limit the relative rotation of the locking nut pair. For example, the use of tooth pins, serial wires and stop washers. Because the locking nut stopper does not have a pre-tightening force, the anti-loosening stopper can only work when the locking nut is loose and returned to the stop position. Therefore, the locking nut method does not actually prevent loosening but prevents falling.

　　2. Riveting and anti-loosening

　　After tightening, use punching, welding, bonding and other methods to make the locking nut pair lose the performance of the kinematic pair and the connection becomes an irremovable connection. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be damaged before it can be disassembled.

　　3. Friction anti-loosening

　　It is the most widely used anti-loosening method. This method forms a positive pressure between the locking nut pairs that does not change with the external force, so as to form a friction force that can prevent the relative rotation of the locking nut pairs. This positive pressure can be achieved by axially or simultaneously pressing the locking nut pairs in two directions. For example, elastic washers, double nuts, self-locking nuts and insert locking nuts are used.

　　4. Structural anti-loosening

　　It is to apply the locking nut pair’s own structure, that is, the Tang’s locking nut anti-loosening method.

　　5. Punching edge anti-loosening

　　After the nut is tightened, the thread is destroyed by punching the end of the thread; bonding anti-loosening generally uses anaerobic adhesive to apply to the thread screw surface. After tightening the anti-loosening nut, the adhesive can solidify by itself, and the actual anti-loosening effect is better. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be destroyed before it can be disassembled.
