Moderate rates of foam formation may be harmless. The small homogeneous particles with large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles will cause explosion. Using activated carbon mat to remove the surface active substances, or through the filtration of foam is not very stable, this is an effective measure; Other measures should also be taken to minimize the introduction of surfactant.
- (8) galvanized wire coated hexagonal mesh is coated with a layer of PVC protective layer on the surface of galvanized iron wire, and then woven into a variety of specifications of hexagonal mesh. This layer of PVC protective layer will greatly increase the service life of the net, and through the choice of different colors, so that it can be integrated with the surrounding natural environment.
The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, 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.
- A lot of pet carriers are designed with a small box at the base, so that pets can clean up when they poo. At the same time, it is also convenient for pets to clean up. For example, if there is no box for leaking excreta, pet excreta will be on the ground, which is quite unsanitary. If you have a box it’s easy to take the box out and clean the trash so it doesn’t get all over the place, so it’s more hygienic.
The wire mesh is composed of low carbon steel wire or medium carbon steel wire, high carbon steel wire or stainless steel wire. There are two kinds of manufacturing technology of steel wire mesh, one is the weaving method, the other is the welding connection, the formation of grid.
Post time: 10-03-23There 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.
- Galvanized wire to galvanized uniform, a body is now its cross section, the second is the longitudinal uniformity. In the actual operation process, such as the jitter of steel wire, the surface of the pot scum and other reasons will cause galvanized wire surface galvanized layer accumulation, should try to solve the problem.
- Steel mesh plastic sprayed: Coating is also we often speak of electrostatic powder spraying coating, it is to make plastic powder charged with static electricity generator, adsorption in the iron plate or other product appearance, and then through 180 ~ 220 ℃ baking, make powder agglomeration adhesion of metal or other objects, plastic product used for indoor use more boxes, paint film present flat or matte effect. Spray powder mainly acrylic powder, polyester powder and so on.
- The positive and negative twisting barbed wire is less than 3 cents per meter, and the corresponding 12 hot dip galvanized barbed wire is 5 cents per meter, no matter from the service life, tensile strength, rust prevention effect is no worse than the 12 iron wire
- ⑵ Can realize the welding of large plate, steel frame, plate – tube, rod – rod, tube – tube and other profiles.
Hot dip galvanizing is a kind of external treatment technology in the production of fasteners. The common varieties of hot dip galvanizing fasteners are electric galvanizing, powder galvanizing, mechanical galvanizing and hot dip galvanizing. Wire factory according to different requirements of customers for fasteners, different hot-dip galvanized surface treatment. Galvanized layer and steel is a metallurgical connection, become a part of the steel surface, so the durability of the coating is more reliable.
Post time: 06-09-22Galvanized wire is processed by low carbon steel wire rod. It is made of low carbon steel, after drawing forming, pickling and rust removal, high temperature annealing, hot dip galvanizing, cooling and other processes. Electrogalvanized iron wire using low carbon steel as raw materials, after drawing, galvanized and other processes completed. It has the characteristics of galvanized layer, strong corrosion resistance, strong galvanized layer, and so on. Galvanized iron wire is widely used in construction, highway walls, Zahua, weaving and other industries.
Cold galvanizing (galvanizing) is in the plating tank after the current unidirectional, so that the zinc gradually plated on the metal surface, slow production speed, uniform coating, thin thickness, usually as long as 3-15g, bright appearance, poor corrosion resistance, usually a few months will rust. Compared with hot dip galvanizing, the production cost of electric galvanizing is lower.
Now 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.
- So why sometimes the size of the bundle is the same, the price will be a little different? This is mainly due to the difference in weight. The lighter the bundle, the lower the price. This is the main factor leading to the relatively large price difference.
The characteristics of these cages are small, light, easy to carry and easy to clean. For small animal cage, the wire diameter of the general iron wire is not very large, the thickness of the plastic is relatively thin, so the use of the time can not be “violence”, otherwise the cage in the “destruction” will occur under the welding or plastic crack.
- Hexagonal mesh is metal wire woven Angle mesh (hexagonal) made of barbed wire, the use of wire diameter is different according to the size of the hexagonal.
Hook mesh is hooked flower machine (diamond mesh machine) for all kinds of metal hooks, can be divided into (lock, twist folding locked two. Data
VC wire, stainless steel wire, low carbon steel wire, wire, galvanized wire. Based on entry, rhomboid net, rhomboid net, ring collection, chain net, collection, anchor net, hook breeding, playing net fence. Appearance disposal: according to electric galvanizing, hot dip galvanizing, plastic hook polyethylene plastic bag, dip plastic, spray plastic, hook mesh. According to the use: decorative hook (simple, guardrail, hook mesh, maintenance of another classification: stainless steel data 201,302,304 hook (left, 316, appearance disposal, none).
Defects such as surface film and surface inclusions can be found and treated by conventional techniques in order to remove them locally from the surface of the deposition layer. Excess foam is formed when soap and surfactants such as saponified fats are brought into the tank.
- 3, PVC plastic coated barbed rope protection function is very good
If the zinc coating is good, but in 3% nitric acid when the light, the coating has dark shadow, passivation occurs when the film is brown, may be caused by foreign metal impurities such as copper or lead in the galvanizing liquid. When problems occur in the process of galvanizing large coil galvanized wire, the temperature and current density are checked first, and then the content of zinc and sodium hydroxide in the plating solution is measured and adjusted through the analysis of the plating solution. Whether DPE content is low can be determined by hull cell test.
Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.
Galvanized silk hook mesh is widely used in warehouses, east and west refrigeration, protective reinforcement, park, zoo fence, Marine fishing fence and construction site fence, machinery and equipment protection. There are two kinds of use, that is, slope protection hook net (slope protection net), coal mine hook net (mine hook net, coal mine support net, roadway support net).
- The most obvious gap in a short time is the cross section. Because the hot-dip galvanized barbed rope is surface anticorrosive treatment, there will be rust in the cross section, while the stainless steel barbed rope because the internal raw materials are consistent with the surface raw materials, so there is no such situation.
River isolation network because of different regions are not close to the same, some places called river guardrail network, reservoir isolation network and called river bridge guardrail and so on, but they refer to the same kind of product, we all know that the river isolation network fence itself is a kind of obstacle, to prevent people and cars falling into the river, if installed river isolation network will not appear such a problem, Its setting is conditional, generally in the river fence set guardrail and more people and vehicles installed guardrail maintenance, the relative risk of discrimination. As long as the correct planning, guardrail to play its own function and advantages. Today, I will introduce to you the style of the river isolation network.
A variety of arc, undivided Angle and undivided elevation ladder mounts are available to provide the ideal treatment plan. It can be used together with the appearance and the design of the common trackless active shift door, forming a harmonious and intact whole.
