How to Choose the Surface Treatment Process for Fasteners

  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.among non standard fasteners It has given great spiritual support to entrepreneurs, and more entrepreneurs will contribute to this industry in the future. 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.

Security for people like Bezos costs about $1.6 million a year.However, in other words, we should know more about it. female bodyguard The law of development has brought new vitality to the whole industry and revitalized the market. http://huanyubodyguard.com/

  

  private bodyguards

  

  Like tech executives in the United States, Chinese tech executives also employ private bodyguards, like the former celebrity Jack Ma, who has elite bodyguards dedicated to providing him with security services and is rumored to be a low-key martial arts master who knows traditional Chinese martial arts. Most Chinese tech executives are surrounded by bodyguards who know kung fu skills like boxing, free combat, kickboxing, Brazilian jiu-jitsu, can drive a car, can dive, know basic business etiquette, and know technical reconnaissance skills. Some of the bodyguards employed by China’s technology giants are from professional bodyguard units such as the Huanyu Brothers Bodyguard Company in Shenzhen, China, and some are security personnel of the security department established by the company’s senior executives.

Single-core Cable and Multi-core Cable

  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.For this reason, it can be speculated that multicore cable price The market feedback will get better and better, which is one of the important reasons why it can develop. 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.

What Are Biodegradable Pla Gloves_

  In daily life, we often use plastic PE gloves. Plastic gloves are disposable items that are easily consumed in daily life. We use a pair for stewed food, a pair for crayfish, and a pair for home hygiene. While plastic gloves provide us with convenience, they also cause a certain degree of environmental pollution due to excessive use and lack of recycling, becoming “white garbage”. As environmental protection becomes more and more important, we need to enhance our environmental awareness and pay attention to this matter.Under people’s attention biodegradable mailing bags Finally grow into what people need, born for the market and come for the demand. https://biodegradable-gd.com

  

  

  Biodegradable PLA gloves are disposable gloves made from polylactic acid (PLA), a biodegradable and bioactive thermoplastic derived from renewable resources like corn starch or sugarcane. Unlike traditional disposable gloves made from synthetic materials such as nitrile or latex, PLA gloves are designed to break down more quickly and sustainably in the environment. Here¨s a detailed look at compostable PLA gloves:

  

  

  Benefits of biodegradable gloves:

  

  1. The performance remains unchanged during the shelf life, and after use, it can be degraded into inorganic substances such as carbon dioxide and water under natural environmental conditions, becoming nutrients for plants and will not pollute the environment

  

  2. Easy to use, not only green and healthy, but also very convenient to use

  

  3. The raw material source of biodegradable gloves is very environmentally friendly. The raw material comes from polylactic acid PLA, which comes from plant resources such as corn and potatoes. It is green, environmentally friendly and sustainable. It will not come from petroleum like plastic PE gloves, which is not sustainable, and the production process is very polluting.

  

  

  When purchasing compostable gloves, we need to try to choose large platforms for purchase. When purchasing, you need to confirm the ingredients of the biodegradable gloves with the merchant, which are generally polylactic acid PLA, polyadipate PBAT, and starch. Others such as PE+starch are pseudo-degradable gloves, not qualified degradable gloves, and need to be purchased with caution.

  

  Biodegradable PLA gloves are a promising alternative to traditional disposable gloves, offering significant environmental benefits through the use of renewable resources and compostable materials. As technology and manufacturing processes advance, the performance and accessibility of compostable PLA gloves are likely to improve, making them a viable option for a broader range of applications.
