Hebei Supplying single strand / double strand barbed wire machine positive and negative twist barbed wire machine

Barbed Wire Category: Folding Edit this paragraph by barbed wire barbed wire barbed wire machinery will be wrapped around the main wire (strand) above, through a variety of weaving from the isolation fence. Three barbed wire twist compilation methods: positive twist, reverse twist, reverse twist. Positive twist law: that is, two wire or a plurality of wire twisted into a double-strand barbed iron wire rope and then wrapped around the double-stranded wire. Anti-twist method: is the first barbed wire wrapped around the main wire (that is, single wire) then coupled with a wire twist compilation partnership with dual stocks barbed wire. Positive and negative twist law: that is opposite from barbed wire wrapped around the main wire to the direction of twist and weaving. Not along the direction of twist and weaving. Surface treatment by Category: galvanized barbed wire, pvc plastic coated barbed wire, aluminum barbed wire. Surface treatment of the reason is to strengthen the anti-corrosion strength and prolong life. Galvanized barbed wire surface treatment is galvanized name implies, can be galvanized and hot dip galvanized; pvc plastic coated barbed wire barbed wire PVC surface treatment process is PVC plastic bag inside a black silk thorn Shengsi, plating wire and Redu wire. Galvanized barbed wire barbed wire is clad just listed a new product, it's a surface coating with a layer of aluminum, which is also called aluminum. We all know that aluminum is not rusty, the surface of aluminum can greatly improve the corrosion resistance, making it longer life. Barbed wire of purposes: for the plant, private villas, residential building on the first floor, building sites, banks, prisons, counterpart, military machine, the cottage, low walls and other places of security, protection. History of barbed wire: about pages in the nineteenth century, the migration of most of the American agriculture farmers began to land reclamation, they were moved west to the plains and the Southwest border. Due to the migration of agriculture, farmers aware of changes in the environment more intense, which marks the eastern woodland gradual shift to more arid western grasslands climate. Because different temperature and geographical location led to both plants and habits are very different. Before land no land reclamation, since over a stone when coupled with the lack of water migration from agriculture because of their lack of adaptation to local agricultural tools with appropriate agricultural technology, many places have no occupation is not the main thing. For new farmers growing conditions in order to meet a lot of people began to set on the barbed wire fence in their growing areas. Due to the migration from east to west, to the majority of people with a raw material, from the initial east they have built stone walls built by piling in the process of westward migration of people and found many tall trees, wooden fence, and from raw materials This aspect gradually extended to the south, letting construction becomes very easy when cheap labor, but in most western rocks due not so abundant with trees, fences set up is not so widespread in the early pioneers of the lack of materials, people The traditional concept of walls can play a protective role through its borders can not again be destroyed by outside forces and other animal abuses, so protection awareness is very strong. Because of the lack of wood and stone, people began looking for alternatives to the most constantly fences to protect their crops. In the early 1860 to 1870, people began to cultivate plants with thorns as walls, but with little success due to the scarcity of plants with the price of expensive, inconvenient construction so they have a been abandoned. Due to the lack of fence leading to wasteland process is not so smooth. Until 1873, a new research changed their plight Illinois Di Boolean invented barbed wire to protect their land. From there I just went into the barbed wire in the course of history in the production process and technology: In China, the most production of barbed wire factory direct galvanized wire or plastic wire processed into barbed thorn twist this series. rope way will increase production efficiency has increased, but sometimes there is not enough barbed wire fixed drawbacks. With the development of technology, and now there are some manufacturers started to add some ginning process, the wire surface is no longer completely smooth, thus greatly improving the stability of spines from the role.
