3mm perforated metal sheet

The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.

The spring steel wire is made of high carbon and high quality carbon structural steel or carbon tool steel wire rod, and its chemical composition, gas content and non-metallic inclusion must be strictly controlled according to the use of the spring. In order to reduce the appearance of shortcomings and decarbonization layer, the consumption of rod billet to stop surface grinding, if necessary, but also stop peeling.

Stainless steel wire drawing is a metal working (stainless steel) process, is a popular surface treatment technology in the stainless steel and aluminum products industry today. It is the effect of drawing stainless steel and aluminum products. So galvanized wire and stainless steel wire are two different products. Defects such as surface film and surface inclusion can be found and treated by conventional techniques in order to locally remove the surface film and surface inclusion from the surface of galvanized iron wire. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.

After the optimization of the process, mass production of 0.80mm electro galvanized steel wire electro galvanized zinc layer quality is controlled within 80 ~ 90g/m2, zinc layer quality dispersion is very small; The results show that the average weight of zinc layer is 14.5g/m2, the loss of zinc layer is less than 5%, and the tensile strength of steel wire is 2300 ~ 2500MPa. It not only effectively controls the quality of zinc layer of raw steel wire, but also reduces unnecessary waste and production cost.

Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device. In the process of composite electroplating galvanized wire, the plating solution must be stirred to obtain the composite coating in which the particles dispersed in the matrix metal. Stirring methods include mechanical stirring, air stirring, ultrasonic stirring, bath circulation, etc.

Industrial rust prevention method: coated with asphalt, iron roof, coated with asphalt, you can prevent rust. Metal coating: Some metal surface will form a dense oxide film, can be coated on the surface of the metal composed of this metal screen. Such as: galvanized iron, tinplate plating, bicycle underwire and some medical equipment are coated with chromium and nickel.

Ordinary blades installed on the walls of the barbed wire fence height in two metres of general construction cost in more than a dozen yuan a metre, but if the prison on the height of the wall construction modest have already reached the four or five meters so that every one meter of the cost of construction in 30-40 yuan, mainly because the work high above the risk is bigger. The construction cost is different, but the price of the blade barbed rope is the same. The construction cost is often higher than the product. In this way, the blade barbed rope factory recommends customers to use the blade barbed rope with better quality to avoid the tedious time and cost of subsequent removal and installation.

Large volume galvanized wire is made of high quality low carbon steel wire rod processing, is made of high quality low carbon steel, after drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Galvanized wire has good toughness and elasticity, the amount of zinc can reach 300 grams/square meter, with thick galvanized layer, strong corrosion resistance and other characteristics. Widely used in construction, handicrafts, silk screen preparation, highway guardrail, product packaging and daily civil and other fields. Galvanized wire is divided into hot galvanized wire and cold galvanized wire (electric galvanized wire).

The life of the “wire”, is actually “low carbon steel wire”, carbon content in less than 0.2%. The surface is usually coated with zinc plating because it is easy to rust. Under atmospheric conditions, the galvanized layer will not rust before most of the fall off, relatively soft. The life of the “steel wire”, is carbon content in about 0.6% of the “carbon steel wire”, or carbon content in about 0.8% of the “high carbon steel wire”, they have enough hardness and elasticity after appropriate heat treatment, high strength. Uses such as winding ordinary spring and so on.

The insulation layer of large rolls of galvanized wire and rigid thermal insulation products can be bound with double strands of galvanized iron wire, and the binding interval shall not exceed 400mm. The pipe or corresponding equipment with nominal diameter equal to or greater than 600mm shall stop reinforcement after binding, and the enclosed galvanized steel wire must be winched. The iron or wood rod should be tightened, but the tightening level should be moderate, not too tight or too loose, and not damage the wire. The consumption of wire and steel wire is generally used in drawing process and galvanized disposal.

Excellent anticorrosive makes its popularity in the feed, the net surface smooth and tidy, increased the look and feel, can be adornment effect, this characteristic makes it to show in the mining industry, due to high quality with low carbon materials as raw materials, to make it unique general iron mesh screen does not have flexibility, determine its plasticity in use process, Thus can be used in the hardware process of deep processing and manufacturing, complex wall batch swing, underground leakage prevention cracking, light mesh body, so that the cost is much lower than the cost of iron screen, more able to understand its economic and practical.
