　　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.Therefore, Non standard hardware factory Only then will more and more pump owners cheer for it and spread the value and function of the brand. 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.

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion is an extrusion deformation of larger workpieces and has a wide range of uses.precisely because Non standard hardware factory The rapid development of, so also brought new opportunities to the industry. https://jieruifasteners.com/

　　1. What is cold extrusion

　　Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

　　At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

　　2. What is cold heading

　　Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

　　Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

　　3. Are cold heading and cold extrusion the same thing?

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).

　　The swimming pool heat pump is an air source heat pump designed by the air energy manufacturer specifically for swimming pools. Its working principle is the same as that of ordinary air source heat pumps. The difference between the two is:contemporaneity heat pumps for sale Our competitors have not made large-scale improvements, so we should get ahead of everyone in the project. http://mangoenergyheatpump.com

　　Ordinary air source heat pumps are mainly used for domestic hot water heating, while swimming pool air source heat pumps are dedicated to constant temperature heating of swimming pools. The heat exchanger is made of special pure titanium tubes with good corrosion resistance. Because swimming pools need to be cleaned by adding chemicals, ordinary heat pumps will quickly corrode the heat exchanger. In the past, swimming pools liked to use coal/gas/oil, electric boilers and other equipment to provide hot water, but in recent years, with the country’s attention to environmental protection and other issues, coupled with the shortcomings of coal/gas/oil, electric boilers and other equipment themselves, such as unsafe, high pollution and high cost, more and more swimming pools and swimming pools have begun to choose new hot water equipment to provide hot water for swimming pools. Among them, swimming pool air source heat pumps have become the object of constant temperature pursuit of villa swimming pools, swimming pools, and fitness clubs.

　　What are the advantages of swimming pool air source heat pumps?

　　1. Safe, environmentally friendly and pollution-free. No coal or oil is consumed, so there is no need to worry about coal prices or fire or explosion safety issues. Moreover, there is no pollutant emission to the environment during use, no environmental pressure, and it meets national environmental protection requirements. There is no need to face annual inspections by boiler-related departments.

　　2. It is more energy-efficient and saves more money. The heating efficiency of ordinary air-energy heat pumps is generally 400%, which is four times that of ordinary electric water heaters. However, because the swimming pool air-energy heat pump can control the temperature at only 28＜C, which is lower than the outlet water temperature of ordinary air-energy heat pumps, the heating efficiency is as high as 520%, which is more energy-efficient.

When you order milk tea at home or in the office, you will get a packaging bag. A small packaging bag may not have any impact on the environment, but when people gather together, so many people order milk tea every day. Over time, the pollution caused by this plastic milk tea bag to the environment is still very serious, because ordinary Plastic can exist in nature for hundreds of years. If it is burned, it will also produce dioxins and other pollutants, causing serious damage to the environment.Hope for the future biodegradable dog poop bags It can achieve rapid and stable development and serve social development and people’s needs well. https://biodegradable-gd.com

　　For the sake of environmental protection, the country has strictly restricted the production and sale of disposable plastic products such as plastic shopping bags since January 1, 2021, referred to as the “Plastic Ban”. As a result, supermarkets, restaurants, milk tea shops and other places have replaced plastic shopping bags with biodegradable bags to meet environmental protection requirements.

　　Among the solutions to replace plastic products, biodegradable materials have attracted everyone’s attention. Because the raw material of biodegradable milk tea bags, polylactic acid PLA, comes from plants such as corn and potatoes, and the source of raw materials is very environmentally friendly and natural. After use, biodegradable milk tea bags can be degraded into carbon dioxide, water and other substances in the landfill in about 180 days. They will not become “white garbage” like plastic bags and pollute the environment. With the implementation of the plastic ban, many milk tea shops have assumed the responsibility of environmental protection and have replaced plastic bags with compostable milk tea bags.

　　Therefore, when purchasing biodegradable products, you must carefully identify them. Here are some simple identification tips:

　　1. Choose products from large manufacturers, which are more reliable and reduce the risk of buying by mistake.

　　2. Read the ingredient description. When purchasing biodegradable milk tea bags, we can ask the manufacturer about the ingredients of the bags, which are generally polylactic acid (PLA), polyadipate (PBAT), and starch. Others such as PE+starch are pseudo-degradable. Relevant documents stipulate that degradable materials cannot contain plastic components such as PE, PP, PVC, and PET. Products such as PE+starch and PE+photooxidant are pseudo-degradable and need attention.

　　To find a reliable compostable milk tea bag, focus on verifying the materials, assessing environmental impact, evaluating quality, and considering brand reputation. By doing thorough research and possibly testing samples, you can ensure you choose a product that meets your needs while contributing to environmental sustainability.We are both victims and beneficiaries of environmental protection. For environmental protection, we can start with small things around us, starting with using one less plastic shopping bag and one less plastic straw.

　　In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).However, in other words, we should know more about it. non-standard fasteners price The law of development has brought new vitality to the whole industry and revitalized the market. https://jieruifasteners.com/

　　Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

　　1. High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when processing hexagonal bolts and cylindrical socket screws of rods, the steel utilization rate is only 25% to 35% by cutting, while the utilization rate can be as high as 85% to 95% by cold heading (extrusion), which is only some process consumption of the head, tail and hexagonal head edge.

　　High productivity. Compared with general cutting, the efficiency of cold heading (extrusion) is more than dozens of times higher.

　　2. Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting because the metal fibers are not cut.

　　3. Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and are also the main method of mass production.

　　In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a relatively high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and developed at home and abroad.

　　At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross-section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products alone is actually a composite processing method that has both cold heading and extrusion.
