sodium benzoate and potassium sorbate preservatives

The height of the shield should not be less than two meters. The length of the shield should be the width of the journey and the extension 10 meters away. The vertical load of the handrail on the bridge is 1.2KM/m, and the horizontal external load is 2.5KM/m, both of which should be calculated separately. Galvanized hook mesh is attributed to a hook mesh, it is the selection of galvanized wire, hot dip galvanized wire as raw materials, woven through the hook mesh crimping truncated.

Blade barbed rope is a new product of safety protection supplies, and other barbed rope is different with very sharp blade, its production process is the stainless steel sheet stamping forming. The blade barbed wire protective net is a new kind of protective net. The blade barbed wire produced by our factory is made of corrosion-resistant hot-dip galvanized steel plate or stainless steel plate.

Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh boxes, the inside of the filler are selected stones, these stones are not easy to wear, and between the stones and stones will retain some gaps, so it is very good to meet the drainage requirements.

There is also in the use of places, blade thorn rope is generally installed and used for the border, walls, prisons and so on, and galvanized thorn rope is in the orchard, fence livestock and so on a large area of installation, although the use of large, but not as high as the use of blade thorn rope and grade, so this is the main reason for the high price. Finally, for the blade barbed wire, the general installation site has high requirements for the protection level, so the quality of the product is also relatively high. But the ordinary galvanized barbed wire has relatively low requirements for the quality in the processing process due to the casual requirements at the installation site.

Wire mesh production of general selection of low carbon wire, after fine and accurate active welding equipment processing, the selection of galvanized process surface treatment. After the completion of the product, the net surface is smooth and regular, good integrity, strong and consolidated, even if part of the choice or pressure will not appear lax phenomenon.

Greenhouse steel pipe is mainly made of greenhouse composite materials made of pull rod, pressure rod, column, and arch rod to cover the plastic film in a greenhouse. Wire factory introduces its this shape is circular plastic greenhouse, this greenhouse covers a large area, the effect of heat absorption is also very good, convenient to build, the cost of building a is also very low. The raw material source of greenhouse steel pipe is very rich and extensive, and the application effect is good.

The formation process of hot dip galvanized layer is between the iron matrix and the outside of the pure zinc layer, the formation of iron-zinc alloy process, the workpiece surface in hot dip plating when the formation of iron-zinc alloy layer, so that the iron and pure zinc layer is well combined. The process of large roll galvanized wire can be simply described as: when the iron workpiece is immersed in the molten zinc liquid, the first zinc and α-iron (body-centered) solid melt is formed on the interface. This is a crystal formed by the matrix metal iron dissolved with zinc atoms in the solid state. The two metal atoms are fused with each other, and the attraction between the atoms is relatively small.

The price of galvanized iron wire performance is the key to win, galvanized wire only with good performance, in order to win the market, in order to obtain customer praise. In galvanized wire, the main function of carbon in increasing hardness, less is less easy to rust, the main function of chromium is acid and alkali resistance; Nickel’s main function is high temperature resistance, acid and alkali resistance and conductive use; The main function of iron is magnetic conductivity; The main functions of titanium are low density, high hardness and strong corrosion resistance. The main function of copper is magnetic and electrical conductivity. Different chemical components have different functions, which together form the characteristics of galvanized wire.

Hexagonal twist flower network is divided into heavy hexagonal network and small hexagonal network two categories. Both are made of steel wire braided with various materials, the difference is that the former uses thicker steel wire, and the latter uses finer steel wire braided.
