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.
For example, Przewalskopeles is a first-class protected animal in China. At present, as long as there are several other przewalskopeles populations around Qinghai Lake in China, according to incomplete statistics, there are only about 1,000 of them left. Stainless steel barbed wire fence net is commonly used in grassland pastoral area of Qinghai Lake, with a height of 1.5 meters.
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.
Bridge protection system generally do not need to be specially installed special drainage system, the use of hexagonal mesh made of gabion mesh box, 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.
1. Simple grid structure, beautiful and practical; 2. Easy to transport, installation is not limited by terrain ups and downs; 3. Especially strong adaptability to mountainous, sloping and multi-curved areas; 4. The price is medium and low, suitable for large area. Main market: railway, highway closed network, field fence, district guardrail, all kinds of isolation network.
Spring steel wire should have high tensile strength, elastic limit, endurance and fatigue strength, and resistance to impact and oscillation. The strength and endurance objectives, especially to prevent the occurrence of modification cracks, are the key to the consumption of spring wire. The inner quality and outer quality of the wire rod directly affect the function of the wire.
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.
Bird cage is a kind of pet cage, is the main environment for ornamental birds to carry out activities and habitat, “work to do a good job, must first sharpen its tools” bird equipment is applicable or not, is one of the key to raise ornamental birds. Therefore, only if the appropriate cage and other accessories are prepared first, can the birds be kept healthy and lively, singing freely and suitable for viewing. There are many kinds of cages, depending on their body shape and habits.
After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated six-sided wire mesh, prolong the service life of the product.
Now, hexagonal wire netting is widely used in Bridges, bridge piers and bridge bracket slope protection, cant bridge bracket, there are many people according to the gradient of slope to choose the right hexagonal wire netting, in gentle slope, people usually use bing slope protection system, and in the case of steep slopes, people will use the guest network gravity walls.
