If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, filtration test, and then take a small amount of electroplating solution, with zinc powder treatment after the test, check the problem is solid particles or copper, lead and other foreign metal impurities caused by. One by one, it’s not hard to find the cause of the problem. Galvanized iron wire coating blister, poor adhesion.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
On the highway, barbed rope protection net is generally to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of road land and other issues of traffic safety facilities. There are many forms of barbed rope protective nets, commonly used metal, woven net, barbed wire and often green gracilaria. Metal braided net is set in crowded areas, barbed wire is used in areas with few people and animals, and the structure of hedges and barbed wire is used in toll stations and service areas. In the past two years, considering the beauty of the problem, in the Pearl River Delta region of some highways with fruit plastic spot welding network (usually said guardrail network), this barbed rope protection network is more good-looking, durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beautiful sections can be used.
- Purpose of galvanized hexagonal net: building wall fixed, heat preservation, heat insulation; Power plant tied pipe, boiler warm; Anti-freezing, residential protection, landscaping protection; Raising chickens and ducks, isolating chicken and duck houses, to protect poultry; To protect and support seawalls, hillsides, roads and Bridges and other waterworks.
- 1, barbed rope protection net center line along the road within the land boundary 20 to 50 cm set.
Post time: 28-02-23- Although many species of parrots are native to tropical regions, birds are susceptible to heat stroke. So in warm weather, don’t put the cage directly in front of a window in direct sunlight, or in an unshaded and unventilated garden.
Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.
- (2) Greenhouse special electric galvanized shaft wire shall not be used for waist hoop compression reinforcement, usually not used for all binding.
The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized 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) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.
Cold wire drawing is a kind of cold processing of metal, that is, we often say reinforcement. Cold drawing process is not messy, cold drawing price based on the quality of cold drawing dividends of different levels, cold drawing production is also a variety of different procedures. The main factor affecting the strength of cold drawing wire is raw materials, which are closely related to the raw materials, strength and diameter of raw materials, and the better the quality of cold drawing wire, the more messy the production process.
Post time: 23-12-22- Of course, the quality of any product is also affected by the implementation of the manufacturer’s norms. If it is the manufacturer of electric welding mesh in production, it does not have a high implementation of the norms, or the procedural norms on the production line have decreased, or there is no higher requirements on the production link.
There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.
- 3. Galvanizing: the preheated steel wire is immersed in the molten zinc liquid, so that the surface is attached with a zinc layer. The control of galvanizing time and temperature has great influence on the quality of zinc layer.
Post time: 08-09-22Hook fence is made of hook fence for the net surface of the protective net, barrier grid. Material PVC wire, stainless steel wire, good low carbon steel wire, galvanized wire, iron wire hook mesh is made of hook mesh machine for various materials of wire hook knitting, can be divided into two kinds of folding, screwing lock.
- One end of the wire must be clearly marked and the other end left on the outer layer for easy connection by other wires. Ask the factory to provide the corresponding quality inspection report before packing. Cold drawing is a kind of material often used in our life, especially in the construction of buildings. Cold wire drawing is used more in building materials, cold wire drawing testing standards are also different.
When the pet consignments need to use a special pet cage, usually domestic pet cage are not qualified. Prior to shipment, the pet must be taken to the airport for quarantine inspection. The quarantine certificate should be attached to the waybill. After confirming your flight, arrive at the airport at least 3 hours in advance, anticipate the waiting time and flight time, prepare enough water and food for pets, hot weather, poor ventilation, etc., will cause harm to pets. Those who want to take pets with public transport, must go to the animal quarantine station, with proof of immunity for the county animal quarantine certificate. Clean and disinfect the pet carrier.
The common barbed rope produced by the manufacturer is the 14*14 type of barbed rope product. Since the warp wire used is the same as the wire diameter of the barbed rope, it is easier to calculate the length and weight. Usually each kilogram of barbed rope can reach about 10 meters of service length. The length of each kilogram of raw material is about 35 meters. Both 35 meters length of raw materials can produce 10 the length of the wire diameter barbed wire cost.
A barbed rope is literally a kind of barbed rope. Generally speaking, the material is made of iron wire or copper wire. People have a very long history of using barbed ropes, as early as the 19th century Americans began to use the first barbed ropes. Function: Its first function is agricultural fence. The origin of the thorn rope is in agriculture. People used the thorn rope to divide the fields into different pieces. Barbed wire is also widely used in fencing until now. Secondly, it is used for protection and protection. For example, people put barbed ropes around the walls of their houses to prevent people from climbing over the walls and entering the yard. There are many other functions such as fire prevention and theft prevention.
After the column is installed and secured, the net can be connected directly to the Internet. The tools required for this step must be special spanner, casing and matching screws. Stand the net in the middle of the two columns, and then force upward to align the net with the connecting accessories of the column.
- 2. Preheating: Put the steel wire into the preheating furnace to increase its temperature in order to better react with the molten zinc liquid.
In the electroplating tank through the current unidirectional make zinc plating on the metal surface gradually, the production speed is slow, the coating is uniform, the thickness is thin, usually only 3-15 micron, the appearance is bright, smooth, beautiful, poor corrosion resistance, generally will rust in a few months. The production process of hot wire plating mainly includes: preparation of the original plate → pre-plating treatment → hot dip plating → post-plating treatment → finished product inspection, etc. According to custom often according to plating pretreatment method.
Post time: 21-02-23Open pit coal mine due to poor air quality, a variety of harmful heavy metals are also more, so the corrosion strength of barbed rope products is particularly large, when using galvanized barbed rope must choose hot plating or plastic coated galvanized barbed rope, although the price is slightly higher, but in the long term development is more appropriate. Besides, when the barbed rope is installed near the coal mine, the pile foundation should be fixed to prevent the barbed rope from falling down due to soil erosion, thus losing the protective effect.
As we all know, iron wire rust is due to contact with water and oxygen chemical reaction, therefore, how to prevent galvanized iron wire rust, first of all, in the storage of galvanized iron wire should choose ventilated dry place, avoid wet or rain leakage, in use, in addition to follow the principle of first in first out, if accidentally caused by the destruction of galvanized layer, should be coated with anti-rust paint treatment, Otherwise, it is easy to lose the protection of galvanized layer and cause galvanized iron wire rust.
Post time: 14-03-23Heavy hexagonal mesh is made of steel wire by special machinery woven hexagonal mesh mesh. This kind of net, after cutting, assembly can be made into fence net, mountain hanging net, vegetation three-dimensional network, combination and so on.
