Blasting and drilling contractor, BHP Billiton, is another major force in the sector
Post time: 12-07-22Steel mesh jinsu appearance treatment: polyethylene thermoplastic powder coatings is also called polyethylene powder coating, is the high pressure polyethylene (LDPE) as the basic material, adding a variety of function additives, colors, its antiseptic powder coating manufacturing processes, jinsu coating layer has the function of chemical, shock, circuitous, acid, salt fog corrosion, decorate a function and has good appearance.
- 6. Before commencing work or extending the period from time to time, cut off 15-20 feet of steel wire from the reel and reknot it, in order to prevent the knot from breaking due to fatigue.
Paint on the galvanized layer, the bonding force between each other has a great relationship with the baking temperature of the paint, and alkyd paint is coated after galvanized, and the adhesion is not a problem. After galvanized to do amino paint, paint adhesion is not very good. Do two bottom two surface, adhesion is good, if the two bottom two surface changed to two bottom three surface, that is, more paint, more baked once, again test adhesion is very bad, bad enough to tear the paint from the galvanized layer.
Annealed wire is mainly made of soft iron wire through low carbon steel heating, hot drawing, constant temperature and other processes. Because of the differences in use, there are also different in the production process, and the specifications are varied. Annealed wire can be widely used, mainly because annealed wire and other kinds of wire, has many advantages.
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.
Heavy duty hexagonal mesh made of steel wire by special machinery woven into a hexagonal mesh net. This kind of mesh can be cut and assembled into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, composite, etc.
Post time: 20-10-22- 4. Choose according to habits
Post time: 17-03-23In GENERAL, THE HARDNESS OF A METAL IS OFTEN CONSIDERED AS THE RESISTANCE OF a MATERIAL TO COMPRESSION PLASTIC deformation, scratches, wear, or cutting. In the adjustment of zinc dip distance of galvanized wire, keep the original speed unchanged, according to the time of zinc dip, wire diameter, and then estimate the zinc dip distance. By adjusting the zinc dipping distance, the zinc dipping time of various specifications of steel wire is shortened by 5s on average compared with that before debugging, so that the zinc consumption is reduced, the zinc consumption per ton of steel wire is reduced from the original 61kg to 59.4kg.
Poor pretreatment before plating; Bath temperature is too low; Poor quality of additives or too many additives and organic impurities will cause poor bonding. The quality of additives also has an effect on coating foaming. Some additives react incompletely during synthesis and continue to polymerize during long-term storage or use. The additive tends to distort the crystal lattice and cause stress, causing the coating to bubble.
- In use, it can be well used to control its soft and hard degree in the annealing process, mainly used in the construction industry as a binding wire and binding line. Of course, its use is not limited to arts and crafts, but also widely used in the construction industry. Earlier woven lanterns were made of iron wire with appropriate candles placed inside. People hung them in front of their doors and looked very beautiful at night.
Select cut wire first of all to ensure that the raw material of the silk is exactly the raw material you need, the raw material to ensure that it will be used well. Choose the straightness is relatively high, so that the length of the truncation will be the same, there will not be a lot of length difference, the length of the truncated wire is a very important element to select the truncated wire.
- After a long time of use, it will not rust after the corrosion protection layer on the surface of hot dip galvanized barbed rope, because the material inside the stainless steel barbed rope is the same as the material on the surface.
- But there are some necessary precautions in the production of galvanized wire. Remove all tools and piles on the work site and equipment that hinder activities, and slowly put the wire into the cylinder during pickling to prevent acid splashing on the body. When adding acid, the acid must be slowly poured into the water. Do not pour water into the acid to prevent acid spillage and injury. Workers should wear protective glasses when working. Then in the handling of wire and other items, it is strictly prohibited to push hard.
- Large hexagonal net called stone cage net, mainly used for mountain preparedness protection, hydraulic construction, etc. Small wire hexagonal net is used as a good material for culture, will twist the hexagonal net in the welding of the iron frame on the hexagonal net welding into chicken cage, pigeon cage, rabbit cage and other cage, hexagonal net is an excellent material for culture with net.
A. When the thickness of the plating is 3-4 mm, the zinc adhesion should be less than 460g/m, that is, the average thickness of the zinc layer is not less than 65 microns.
- 5. The bird cage should be sprayed with transparent wood environmental protection paint every 1-2 years. This protects the cage’s skeleton from the effects of weathering.
- The tensile resistance of welding net to 120N, otherwise for unqualified welding net. In this respect, there is no simple way to test the tensile resistance of the welding net, only through professional tools, expert testing to test, we will not introduce in detail. The outcrop on both sides of the welding net should not exceed 2MM. The welding net diameter wire and weft wire crossing place should be welded firmly, but the edge of the welding net to weld firmly weft wire must come out some, to weld firmly, but can not come out too much, generally not more than 2 mm is qualified welding net.
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.
In order to remove the photosynovium and oxide remaining on the surface of galvanized iron wire after drawing or heat treatment, it is necessary to do the surface treatment of galvanized steel wire before plating. The common surface of low carbon steel wire is the light synovium or oxide of animal or vegetable oil; Medium and high carbon steel in addition to contain animal or vegetable oil components.
Post time: 13-06-24Now the production of stainless steel blade barbed rope unless it is a specially customized model, under normal circumstances are the use of a knife length of 22mm mold production, that is, we usually say bto-22 type. It’s not necessarily the case that there are specifications from 11mm to 65mm. Unless the customer insists on customizing the required length, the barbed rope manufacturer produces bto-22 stainless steel blade barbed rope.
- The acid activation solution in the production process can remove the corrosion products and oxide film on the surface of the low carbon steel wire without excessive corrosion to the matrix. Galvanized wire can be zincate galvanized or chloride galvanized process, should use appropriate additives to obtain the low carbon steel wire standard requirements of the coating. When galvanized wire after light plating should be light treatment. Control the temperature of the bath of galvanized wire.
