The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.
- It is generally believed that the positive and negative twisting wire wire is not as durable as the thickness, common sense thinks so, but the positive and negative twisting wire wire is used in hot galvanized steel wire, which is more than 3 times the tensile strength of the iron wire, and the zinc amount is not lower than the hot plated wire
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. The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion on the matrix.

People who want to keep birds for the long term need to know how to choose the right cage and how to raise them scientifically. It’s all about the birds’ daily life and health. Only by knowing more about the various aspects of raising birds can they be raised healthy and lively, singing freely and suitable for viewing.
Dip plastic hook net disposal characteristics and downwind, dip plastic is also a common comparison, surface treatment color comparison is single, generally dark green, however, if you want to change into other colors, dip plastic will be more convenient. Because its inner line or inner tube is generally iron line, so, after a period of time, the inner line or inner tube will slowly corrode outward, compared to the outside of the glue fade, hook net will die.
- Due to the implementation of the grassland contract operation obligation system, herdsmen have a high capacity to strengthen and raise their stainless steel barbed rope fence net in grassland pastoral areas, forming the phenomenon of high density and high height of stainless steel barbed rope fence net in grassland pastoral areas, which is destructive and even destructive to the survival of wild animals.
Post time: 16-05-23Hot wire mesh in the building wall engineering mainly played the anti-crack effect, inside and outside the use of specifications are not the same. Hot dipped wire material choose low carbon wire, through automation welding precision machinery processing after forming, surface treatment by zinc immersion process, galvanized barbed wire surface smooth and tidy, uniform structure strong, the overall performance is good, even if the local cutting or under pressure will not loose phenomenon occurs, it is the iron mesh strong anticorrosion performance in one of the widely used net class.
- In the corner area, the zinc layer is often thicker than other places, and has good toughness and abrasion resistance. And other coatings in this corner, often Z thin Z is not easy to construction, Z is easy to hurt, so often need to be maintained. Even if there’s a lot of mechanical damage or something. Causing a small layer of zinc to peel off, leaving the iron base exposed, the surrounding zinc layer will act as a sacrificial anode to protect the steel from erosion.
Post time: 16-05-22The basic components of the bird cage are plate top, cage frame, cage bar, cage door, cage hook, dragon ring, bottom ring and cage bottom. The accessories are composed of dung board, sun rod, bird seed pot, water tank, jade finger, horsetail string, etc. These parts are usually made of wood or bamboo, and can be carved and hollowed out with a variety of laser machines.
The amount of zinc on the surface of high zinc barbed rope is about 5 times that of general zinc barbed rope, thus greatly prolonging the time of rust resistance. In the appearance of the two products are silver white and metal texture is better, for the distinction between the two products is more difficult to distinguish if it is a layman, but for long-term work of professionals can be separated from the two at a glance.
- Galvanized iron wire is divided into hot-dip galvanized wire and cold galvanized wire, using low carbon steel wire processing, after drawing forming, pickling rust removal, high temperature annealing, hot-dip galvanized, cooling and other processes. With good toughness and elasticity, the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can cut off the tie wire used in the building, the length is 20cm 30cm 40cm, can be cut off according to the requirements.

Stainless steel welding mesh can be used in the construction industry, highway, bridge for reinforcement. Used for mechanical protection, industry, agriculture, construction and so on.
- The cleaning agent used for cleaning has no effect on the adhesion of the coating and no corrosion on the base material. Acid activation Acid activation solution should be able to remove corrosion products and oxide film from the surface of parts without excessive corrosion of the matrix. Zinc plating may be zinc plated with zincate or chloride and appropriate additives shall be used to obtain a coating that meets the requirements of this standard. After light plating, light treatment is carried out. Passivated parts requiring hydrogen removal shall be passivated after hydrogen removal. Activation with 1% H2SO4 or 1% hydrochloric acid for 5 ~ 15s prior to passivation.
Large roll of galvanized wire alloy elements in iron ore, can make copper through the material thickening degree of strengthening, hardness, impact force, strength resistance, closing rate, elongation, so alloy iron in the exercise of good iron, is an important supplementary element. The difference between galvanized wire and general iron wire is very big, general iron wire is cheap, and because iron is not very stable, easy to rust in wet places, so the stability is not very good, life is not very long.
