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.
If not packaged, then a car of blade thorn rope can not be loaded with many pieces, but also relatively occupied places and easy to be lost in the process of transportation. Each bundle of blade barbed rope is 50 bundles. After hydraulic compression, the volume is reduced and it is more convenient to load and unload. Forklift trucks can load and unload easily. In general, when exporting, the blade thorn rope will be packaged for sale, so that the volume occupied in the container is relatively small, which can be very easy to size and place will not take up much place.
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
Electric galvanized wire direct selling is in the plating tank through the current one-way to gradually zinc plating on the metal appearance, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower. The difference between cold galvanizing and hot galvanizing: the difference between cold galvanizing and hot galvanizing is that the amount of zinc is different. They can be identified from the color. The color of cold galvanizing is shiny silver white with yellow. Hot dip galvanizing shiny white.
No matter how old dogs are, they seem to love to touch noses with people and other animals. In fact, dogs touch noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t nuzzle every human or every animal. They pick and choose who to nuzzle. If they don’t like you, or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell the puppy’s body.
Pet cage is generally made of high quality iron wire, low carbon steel wire, stainless steel wire welding, its characteristics are beautiful, light, folding, easy to store. Pet cage surface treatment is generally: cold galvanizing, hot galvanizing, spraying, dipping, chrome plating, nickel plating and other methods. Pet cage is mainly used for family breeding pets and protection. Tianfu metal products company specializes in the production of various specifications of pet cage such as pigeon cage, dog cage, bird cage, parrot cage and so on.
The 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.
Galvanized wire can be seen as iron wrapped in carbon. When extinguished, the surface layer is more shallow than carbon can contact with oxygen, produce carbon dioxide gas, and radiate the iron wrapped in it. The more carbon galvanized wire contains, the more obvious the phenomenon of spark. The carbon wrapped in iron acts as if it were an explosive in a charge bag, occasionally blowing the iron apart. Sodium and magnesium contain few flammable impurities, and when extinguished, they just glow.
