China Hex Bolt Manufacturers Introduces The Maintenance Requirements Of Hexagon Socket Bolts

China Hex Bolt Manufacturers introduces the techniques for dealing with bluing of hexagon socket bolts:

1. How to deal with bluing:

At present, the more commonly used methods are: the traditional alkaline heating blackening and the later normal temperature blackening, and the latter is not good for the treatment of low-carbon steel. As for the bolts made of A3... see more steel, alkaline hair is generally used. Black: It means turning black once and turning black twice. In the blackening process, the first thing to do is to configure the blackening liquid. The main components of the blackening liquid are sodium hydroxide and sodium nitrite. In the actual treatment process, it is necessary to pay attention to the degreasing and rust removal work before the bolts are blackened, so as to facilitate the passivation and oil immersion after use. The quality of blackening treatment has a lot to do with these processes.

2. Metal "blue" liquid medicine:

The more common methods are alkaline oxidation or acid oxidation. An oxide film is formed on the surface of the metal to prevent the surface of the metal from being corroded. This treatment method is called "bluing". After the black metal surface is "blued", an oxide film will be formed on the surface. The inner layer of the oxide film is ferrous oxide and the outer layer is ferroferric oxide.

When using alkaline oxidation "bluening" liquid, be sure to clean the surface of the bolt first. During the treatment, it is necessary to analyze whether the ingredients in the liquid meet the requirements at intervals of one week. "After the blue treatment" It needs to be rinsed with water. When using the acidic oxidation method "blue" chemical solution, pay attention to the "blue" working temperature should be 100%, and the treatment time should be 40 to forty-five minutes.

Heavy Duty Motorcycle Chains Manufacturers Introduces The Rules Of Using Sprocket

Heavy Duty Motorcycle Chains Manufacturers introduced that the tightness of the sprocket should be appropriate during the use. Too tight will increase power consumption and the bearings will wear out; if the sprocket is too loose, the sprocket will easily jump and fall off the chain. The tightness of the sprocket is: lifted or pressed down from the middle of the sprocket, about 2%-3% of the center... see more distance between the two sprocket. The sprocket should not swing and skew when installed on the shaft.

When the sprocket is severely worn, the new sprocket and the new sprocket should be replaced at the same time to ensure good meshing. The new sprocket is too long or stretched after use, which is difficult to adjust. You can remove the chain link depending on the situation, but it must be an even number. The sprocket should be filled with lubricating oil in time during work. When the machine is stored for a long time, the sprocket should be removed and cleaned with kerosene or diesel oil, and then coated with oil or butter and stored in a dry place.

Copper metal cable joints can be seen everywhere in our lives, and its appearance does bring convenience to people's lives. Below, Hose Fittings Manufacturers will give a general introduction to its features.

1. The price is close to the people. Copper metal cable joints are mainly used in electrical equipment. They are several connection points of the cable line. The main task is to make the... see more line run smoothly. It is so common in life, but because of its wide range of uses, the product is produced in large quantities on the market, resulting in the relatively cheap price of the product, which is undoubtedly economical for consumers.

2. Simple structure, easy to install and replace. Copper metal cable joints can be used outdoors and indoors. Each form and structure is different, but it is basically the same.

Motorcycle Chains Manufacturers Introduces Why Chains Are Aging
Although stainless steel chainplates are much better than ordinary carbon steel chainplates, there are still some substances in the environment that will affect them. Motorcycle Chains Manufacturers introduced the aging factors that cause it, including oxygen, ozone, heat, light, and mechanical stress. Moisture, etc., so all aspects need to be paid attention to extend the service life of the product.

Oxygen undergoes... see more a free radical chain reaction with rubber molecules in the rubber, and the molecular chain is broken or excessively cross-linked, which causes the change of rubber properties. It is one of the important reasons for rubber aging, and the chemical activity of ozone is much higher than that of oxygen. More destructive, it also breaks the molecular chain.

Increasing the temperature can cause the thermal cracking or thermal crosslinking of the rubber, increase the oxygen diffusion rate and activate the oxidation reaction, thereby accelerating the rubber oxidation reaction rate, thereby aging the stainless steel chainplate. The stainless steel chain plate will break the rubber molecular chain to generate free radicals under the repeated action of mechanical stress and the continuous friction process with the idler roller, trigger the oxidation chain reaction, and form a mechanochemical process. In addition, it is easy to cause ozone cracking under stress.

There are two negative effects of water on stainless steel chainplates. On the one hand, it is easy to damage when wet air is exposed to rain or soaked in water. This is because water-soluble substances and clear water groups are extracted and dissolved by water. On the other hand, it is caused by hydrolysis or absorption, especially under the alternating action of water immersion and atmospheric exposure, which will accelerate the damage of the stainless steel chainplate.

The so-called other factors refer to chemical media, variable metal ions, high-energy radiation, electricity, and biology, etc., which will affect the stainless steel chain plate to varying degrees, so it is required to strengthen attention to the use of stainless steel chain plates from different aspects.

Stud Bolt Manufacturer Introduces The Use Of External Hexagonal Bolts

Hexagon bolts are mainly used on mechanical equipment more frequently, and their main function is to connect. Once a fracture problem occurs during use, it will naturally affect the performance of the mechanical equipment and cause the mechanical equipment to fail to operate. Stud Bolt Manufacturer introduces how to prevent external hexagon bolts from breaking?

1. When using, you should choose matching... see more outer hexagonal bolts. If the bolts and the connecting materials do not match, it is easy to cause breakage.

2. When assembling, it is necessary to control the force and tighten according to the specified standards. The tightening force is too large or too small, it is easy to cause the bolt to break, if it is too small, it cannot be tightened firmly. It is recommended to use a torque wrench as a tool when assembling.

3. When the mechanical equipment is running for a period of time, you need to check the usage of the outer hexagonal bolts. If the bolts are found to be loose, they need to be tightened. If the bolts are aging, they need to be replaced in time.

4. Every time you use it, you need to check the guiding part of the outer hexagonal bolt. There are cracks on the head and thread, and observe whether the pitch and shape of the thread are normal. If there is an abnormal condition, it cannot be used.

5. Hexagon bolts are very common in life. In order to make the connection between two things stronger and safer, we must choose the right bolts and use them correctly to reduce the occurrence of breakage during use.

Through the above introduction, Bolts Factory hopes that you can simply refer to the content of this article in future use.
