The basic components of the bird cage are plate top, cage rack, cage bar, cage door, cage hook, dragon ring, bottom ring, bottom of the cage. The accessories are composed of poop board, sun bar, bird food pot, water tank, jade finger, horsetail string and so on.
Post time: 04-11-22The anticorrosion of these raw materials is very different, and the use of life is not the same. Niu LAN net cold galvanized, also known as electroplating, galvanized quantity is very little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) on the amount of zinc in 60 grams to 400 grams, the service life is about 20-60 years, corrosion resistance is general.
1. Used for mountain farming, road isolation, large farming enclosure protection, it is recommended that you choose 3mm wire diameter products.
First, galvanizing can enhance the corrosion resistance of the product. Zinc has high potential and excellent anodic protection. When the surface of the product is galvanized, zinc will have an electrochemical reaction with oxygen and water in the environment, thereby forming a dense zinc oxide protective film, preventing the metal from further contact with external oxygen, water and other substances, slowing the corrosion rate of the metal. Galvanized products after wire drawing processing, because the surface of the product has a more dense zinc oxide protective film, it can better resist external corrosion and improve the corrosion resistance of the product.
And high quality data and production cost and production conditions are bound, so some welding screen manufacturers did not meet the requirements of this aspect, natural in this case there is no way to improve product strength. In addition to data, and produce process, even if again good data, but the factory did not meet the requirements of production process in welding, also can form the product under the high pressure welding, so it is also a kind of strength on the decline, process conditions of different manufacturers also have very big difference, so it formed a shopping mall on the above products are differences of strength.
On the contrary, the denser the ion deposition, the better the quality of zinc layer. Under the condition that the surface zinc layer is dense and bright, the quality of zinc layer per unit area should reach 80g/m2, and the process parameters should be optimized as follows: current density is 16-20A /dm2, mass concentration of zinc sulfate solution is 500g/L, and pH value is 2.5-3.0.
Post time: 19-04-23- The utility of the hexagonal net in the playground is very superficial, in each city to build the playground, are less than the shadow of the hexagonal net. In the stadium around the installation of hexagonal nets, not only can improve the stadium group image, but also convenient city residents to carry out a row of activities. Because the size of the plane or the surface of the object in the urban area is relatively small, many stadiums are built in the more prosperous and lively section, with the hexagonal net as a protective barrier, so it greatly reduces the spherical three-dimensional fly out of the field so as to affect the traffic order of bad things.
“In the booming pet industry chain, pet supplies market occupies a large share, which covers hundreds of categories such as toys, food, clothing and thousands of products.” An industry insider pointed out that the country’s pet supplies market is characterized by a wide variety of products, little competition and huge market potential.
- 4, barbed rope fence and culvert intersection, such as the ditch is narrow, barbed rope barbed rope fence can be directly across the ditch is wider, barbed rope barbed rope fence is difficult to cross, can take bridge, channel processing method.
Post time: 19-08-22- No less than 5 disks should be extracted from each inspection lot for diameter error inspection. 1 point of steel wire should be extracted from each disk to measure steel wire diameter, and the actual diameter of steel wire at this point should be taken as the average value of the two vertical directions. The diameter error of cold-drawn low carbon steel wire should conform to the rules in the table below. The unqualified inspection batches shall be checked one by one, and the qualified batches can be used for engineering.
Barbed rope used to enclose cattle, sheep and other livestock is also the biggest characteristic of low price, for users engaged in breeding industry, the investment is not small, the use of barbed rope fence on the one hand is to reduce the cost, on the other hand, is better protection effect.
- Choose a well-structured crate, such as one with a tray under it so the dog can pee and defecate in it. It’s also easy for the host to clean up.
With the improvement of living standards and the reduction of family size, keeping pets is becoming a way of life for many people. According to statistics, the number of pet dogs has reached more than 100 million, and the trend is increasing rapidly every year. Beijing alone had more than 900,000 licensed dogs in 2010, according to a survey, and the number of pet cats is also very large.
Pay attention to safety in line collection and operation, others without the consent of the monitor, Ben have to get on the bus operation. The reels should be placed lightly, stacked firmly and neatly, not more than 5 reels. Direct contact with acid and alkali must be prohibited. When the acid fog exceeds the specified target of the state, measures should be taken to control it in time, otherwise production is not allowed.
- Reverse twisting of the barbed rope: first wrap the barbed wire around the main wire (that is, a single piece of iron wire) and then add an iron wire and twist together to form a double strand of barbed rope.
In strict accordance with the multi-pass small compression rate drawing, the total compression rate is 96.48%, reducing the scraping of zinc layer. The whole wire drawing die is made of tungsten steel die and polycrystalline die. The Angle of the working cone of the wire drawing die is 12° ~ 16°, and the length of the sizing belt is 0.15 of the diameter of the wire, so as to ensure that the deformation of the zinc layer is basically synchronous with the steel wire substrate.
Generally speaking, in dry main gas and indoor use, the thickness of galvanized coating is only 6-12μm, but under poor environmental conditions, the thickness of galvanized coating is 20μm, can reach 50μm. Therefore, environmental factors should be considered when choosing the thickness of galvanized layer. Galvanized layer after passivation treatment, can naturally form a layer of bright, beautiful color passivation film, can obviously improve its protective function, decorative.
Annealed wire is mainly through low carbon steel heating, hot drawing, constant temperature and other processes made into soft iron wire, because in the use of different, so there are different in the production process, made of a variety of specifications. Annealed wire can be widely used, mainly because annealed wire and other kinds of iron wire, has many advantages.

Post time: 19-05-23- The hoop diameter of 8mm is combined with the cement column guardrail specially customized and equipped with nuts and anti-theft washers. The surface treatment is galvanized, respectively. There are three kinds of bracket hoop at the column cap, bracket hoop at the center column, bracket hoop with encryption bracket, etc. The protective effect of nematocyst rolling cage is good.
