Do You Know The Knowledge Of Barbed Wire?

Wire baskets were mainly used for the movement of slow infantry and vehicles in the war years. Fixed barbed wire is constructed with barbed wooden stakes and iron wires. Mobile barbed wire is shipped from the factory to the battlefield for temporary installation. It is 70-90 cm in diameter and about 10 meters long. The destruction intensity is high, which can slow down the movement of vehicles such as armored cars. When people mention barbed wire, people usually think of special scenes such as battlefields, prisons, and border lines. Indeed, once barbed wire was invented, it was widely used in military and defensive projects; nowadays, barbed wire is also widely used in peaceful times. Wire screen supplier introduces you:

A famous economist believes that barbed wire is "one of the seven patents that changed the face of the world." It played a role in clarifying property rights in the development of the western frontier of the United States. It is with this barbed wire that ranchers can distinguish their own pasture from others' pastures. Because barbed wire is easy to produce, simple to install, and cheap, it can effectively isolate livestock and reduce the probability of personal property theft. Today, on the grasslands of Australia, one can still see the barbed wire left by the colonists when they came here to open up land more than 100 years ago.

Wedge Wire Screen Flat Panels

When it comes to barbed wire, people often think of terrible live barbed wire such as battlefields, prisons, high walls that cannot be seen, barbed wire, borders, etc. Everyone may remember Schindler's list, Auschwitz concentration camp, slag cave concentration camp, The barbed wire is a tool for terror and freedom. Indeed, once barbed wire was invented in history, it has been widely used in military and defense engineering. Nowadays, in times of peace, barbed wire is not only used in machinery, electronics, pharmaceuticals, petrochemicals, glass, food drying, plastics, papermaking fiber, picture tubes, etc Various industries, and barbed wire is also widely used in all aspects of agriculture and life. Barbed wire has recently been applied to rock planting.

Several Questions About Stainless Steel Wire Mesh

Inspection method of customized stainless steel cone strainer:

Inspection of knitting accuracy. It is divided into 3 levels: first-level accuracy, the limit deviation of the mesh cannot exceed 6%; second-level accuracy does not exceed 9%; third-level accuracy does not exceed 12%; mainly the inspection of the arithmetic  mean of mesh Inspection of large mesh size.

Inspection of the quality of weaving. It is impossible for metal wire mesh to be free of manufacturing defects during the production process. Generally, metal meshes delivered in rolls are not allowed to have major defects, a small number of important defects are allowed, and a certain number of general defects are allowed.

Stainless Steel Mesh Filter Disc

The following conditions of the stainless steel filter on the weaving process are major defects: the warp and weft are not firmly intertwined, and the two warp and weft threads are rubbed up and down, and the warp and weft threads have obvious loose displacement. The natural curl diameter is less than 80mm; the mesh is less than 0.18mm, and the natural bend diameter of a 1m long mesh is less than 60mm, which should be judged as unqualified.

The main function of air bleed screen filter mesh:

Due to the long-term industrial pollution, which has caused the decline in air quality, we all know that no matter what the circumstances, the untreated air, etc., contains a lot of harmful substances. Production has a great impact, and it is also harmful to our bodies.The quality of the products produced will also be substandard.

Air filters can greatly help production, improve the quality of compressed air and reduce the cost of production. Air filters are generally made of stainless steel, which are selected according to different filter materials and designs. Filter elements come out, so that we can meet our requirements for water quality.

The air filter is a fast device that can be selected, so that it is more convenient and simple to exchange the filter element, and it is more convenient for us to clean it.This kind of equipment is used in many industries, and it is also the best equipment for each type that requires filtering treatment. The anti-corrosion of the air filter is very strong.

How to clean the sintered mesh filter cartridge:

Sintered mesh filter cartridge plays a very important role in filtering equipment. Regular cleaning plays a very important role in the service life of the filter and the purity of the filter product, especially in some chemical industries. In sewage treatment systems, high-precision products require frequent cleaning to obtain qualified products.

The surface of the product is woven from metal wire, and the filtration accuracy is relatively concentrated. If you must pay attention to surface scratches during cleaning, if the structure is damaged, it is equivalent to directly damaging the entire set of filter products.In addition, stainless steel filtration that needs attention The net is not always cleanable, and the products have a certain service life.

Inspection Method Of Metal Mesh Filter

Metal mesh filter is a professional term for the filtration industry. Purification equipment is needed to purify the original ecological resources and the reuse of resources. Now metal mesh filters are mainly used in oil filtration, air filtration, water filtration, air filtration and other filtration industries. It is used to remove a small amount of solid particles in liquid or air, which can protect the normal operation of the equipment or clean the air. When the fluid enters the filter element with a certain size filter, its impurities are blocked, and the clean fluid flows out through the filter element. The metal mesh filter element allows the liquid (including oil, water, etc.) to clean the contaminated liquid to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness. Air cleans the polluted air to the state needed for production and life, that is, to make the air reach a certain degree of cleanliness.

Everyone knows that many things in our life need to be replaced when they are used for a long time, but some of them are replaced at a high or low frequency. As for metal mesh filter elements, the main reasons for frequent replacement of metal mesh filter elements are Which ones?

1. The quality of raw water is unstable and frequently fluctuates, which leads to too much particulate matter entering the metal mesh filter, resulting in shortened cycle. The pretreatment effect of the metal mesh filter element is poor. The flocculants and scale inhibitors added in the pretreatment are incompatible with each other or do not match the water source. The formed sticky substance adheres to the surface of the filter element, resulting in a decrease in the effective filtering area of the metal mesh filter element, causing The filter element is changed frequently. The quality of the metal mesh filter element is not good. The inner and outer pore diameters of the poor quality metal mesh filter element are basically the same. In fact, only the outer layer plays the role of interception. The good filter element pore diameter is gradually reduced from the outside to the inside. μm, the amount of pollution is larger and larger, and the long time used can also ensure that the effluent quality is qualified.

2. Through the re-examination of the metal mesh filter element, it has the characteristics of strong corrosion resistance, good permeability, high strength, convenient cleaning, high filtering accuracy, clean filter materials, and no silk screen peeling. It also has the advantages that ordinary steel wire mesh cannot match Such as high strength, good rigidity, stable grid shape, etc. Due to the reasonable matching and design of the space, permeability and strength characteristics of the material, it has good filtration accuracy, filtration resistance, mechanical strength, abrasion resistance, heat resistance and Processability and comprehensive performance are significantly better than other types of filter materials. The standard material of the metal mesh filter is 316L, the size is 1200 mm by 1000 mm by 1.7 mm, and the filtering accuracy is controlled at 2-300um. All metal mesh filters are produced All are carried out according to production standards and can be used for precision filtration of various hydraulic oils and lubricants in the machinery industry. Filtration and purification of various polymer melts in the chemical fiber membrane industry. Filtration of various high-temperature corrosive fluids in the petrochemical industry. Filtration, washing and drying of pharmaceutical industry materials. Homogenization of gases in the body industry. As a fluidizing plate for the steel industry. And splitting devices in explosion-proof electrical installations.

3. Five layer sintered mesh, also known as multilayer metal sintered mesh, is made of woven wire cloth with special lamination and vacuum sintering. It has high mechanical strength and overall steel. A new type of filter material. The meshes of each layer of wire mesh are staggered with each other, thereby forming a uniform and ideal filtering structure, which makes the material have advantages that ordinary metal wire mesh cannot match.

Five Layer Sintered Mesh

4. In the process of vacuum sintering of round hole metal filter screen, three obvious changes in vacuum degree are generally observed, that is, three times of a large amount of gas emission in the cemented carbide sintered body. The temperature at which the degree of vacuum changes for the first time is about 350 ° C. The main reasons are: first, the gas adsorbed on the particle surface is desorbed under the influence of temperature and negative pressure; second, the forming agent in the compact is volatilized in large quantities. The temperature at which the degree of vacuum changes for the second time is about 1100 ° C. The main reason for the significant change in vacuum is that the oxides in the compact are reduced by carbon (the reaction temperatures of WO3, TiO2 and C are 993 ° C and 1103 ° C, respectively). CO gas. The temperature of the sintered mesh filter element at the third vacuum degree change generally occurs at about 1350 ° C. At this time, the furnace temperature is above the eutectic temperature, and a liquid phase appears in the sintered body. In a vacuum state, the viscous liquid phase is prone to volatilization loss. Both physical and practical results show that the vacuum in the furnace is high, the sintering temperature is high, the sintering time is long, the content of the binder phase is high, the carbon content in the sintered body is high, and the volatilization loss of the binder phase is greater.
