In the calculation process of 12*14 specifications of barbed rope, it can not be calculated according to the above calculation formula, because first of all, two specifications of raw materials are used, the thinner the wire diameter, the higher the processing cost. Generally speaking, a kilogram of 12*14 barbed rope can reach about 7.5 meters, and the ratio of warp wire to barbed rope cannot be calculated according to the traditional ratio of 7 to 3. The specific use of how much wire and silk need to go through a series of professional measurement but also increase the loss of raw materials and other factors to calculate. Thorn rope factory will also according to customer needs to calculate the reasonable amount of customer use.
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.
Large roll galvanized wire is processed by low carbon steel wire rod, through drawing molding, pickling rust removal, high temperature annealing, cooling and other processes. Large roll galvanized wire electroplating temperature should be controlled in 30-50℃. Because of the strong corrosivity of chloride ions in bath, quartz glass heater is generally used. Continuous production does not need heating, but need cooling cooling.
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.
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.
The cage door must be open so that the puppy can get out at any time. Once the puppy gets used to the dragon, it will go in without you urging it. Close the door for a few minutes when the puppy is having fun. But keep the crate in a busy area of your home, such as the kitchen. The puppy is relaxed and asleep in the safety of its cage. Cage trained puppies should not be caged for more than two hours during the day (unless you have to, but as soon as you get home from work let the puppy out). After getting used to the crate, the puppy is willing to stay in the playpen. Some dogs can’t stand the small space in a crate, but puppies are less likely to have this problem.
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.
Stainless steel material refers to air, steam, water and other weak corrosive medium and acid, alkali, salt and other chemical corrosive medium corrosion of steel, also known as stainless acid-resistant steel. In practical application, the steel that is resistant to weak corrosive medium is often called stainless steel, and the steel that is resistant to chemical medium corrosion is called acid resistant steel. And galvanized wire has 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. Products are widely used in construction, handicrafts, silk mesh, highway fence, product packaging and daily civilian and other fields.
In use, there is no need for daily maintenance and maintenance, not only can save a lot of time, but also can reduce costs, but also has good stability, strong corrosion resistance, greatly prolong the service life. According to the different process is divided into different types, can choose according to their own needs. With good flexibility and elasticity, the main role of annealing wire is to control its degree of softness and hardness, in the production of annealing wire is made of steel wire, now more used in the construction industry binding use, compared with ordinary wire is also more soft, have better luster.
Wire flexibility and elongation is good, can withstand the pressure of mechanical operation, in our country’s industry has played a very important role. There are many kinds of iron wire, the most common is to give black iron wire, galvanized iron wire. The corrosion resistance of the outer coating is effectively improved, but the phenomenon of crevice corrosion will be found after long-term use.
The insulation layer of large rolls of galvanized wire and rigid thermal insulation products can be bound with double strands of galvanized iron wire, and the binding interval shall not exceed 400mm. The pipe or corresponding equipment with nominal diameter equal to or greater than 600mm shall stop reinforcement after binding, and the enclosed galvanized steel wire must be winched. The iron or wood rod should be tightened, but the tightening level should be moderate, not too tight or too loose, and not damage the wire. The consumption of wire and steel wire is generally used in drawing process and galvanized disposal.
