Manipulation of the grp stack is achieved through system calls such as setgid(), getgid(), and initgroups()
Post time: 25-04-23The cage should be strong so that the bars cannot be bent or damaged by the parrot, and weak bars can be bent or damaged by the parrot and injure the parrot. Cages made of plastic coated railings can cause parrots to eat the coating and are not suitable. Quality cages are made of stainless steel, especially those made of colorful mild steel railings. Railing spacing is very important for the parrot’s safety, and the railing should always be small enough to prevent the parrot from poking its head out between the railing gaps. For small parrot species, column spacing of 1/2 inch (1.3 cm) is necessary. Medium parrot species such as grey parrots and Amazons require a 1 inch (2.5 cm) pitch, while great macaws can reach a pitch of more than 1 by inch (3.8 cm).
Post time: 24-04-23Large hexagonal mesh called stone cage net, is mainly used for mountain protection, hydraulic construction and so on. Small wire hexagonal mesh is used as a good material for breeding, will twist twist hexagonal mesh in the welded iron frame on the hexagonal mesh welding into chicken coop, pigeon cage, rabbit cage cage cage, hexagonal mesh is the best material for breeding with a net.
Some customers are more concerned about quality problems, so for the service life is more important, barbed rope factory will generally recommend the use of high zinc barbed rope or stainless steel barbed rope.
Post time: 24-05-23- 3, the barbed rope protective net in the bridge, channel, should be in the direction of the bridge cone slope (or end wall), should not leave people, animals can drill into the gap.
Post time: 26-07-22Before wall plastering, the wall column is connected to the gap construction wire mesh, which can play a certain strengthening and heat preservation effect. The mesh is hung on the interface surface of different grassroots, and the length of each side should meet the requirements of 100mm, so as to prevent shrinkage and cracking caused by different grassroots. Mesh wire diameter can also determine the effect and efficiency of construction, mesh fine laid up convenient soft, high construction efficiency; Of national standard can assure quality, but laid respect is inferior to fine construction fast.
- C, coating uniformity: galvanized layer is basically uniform with copper sulfate solution test etched five times without exposing iron.
- 2. Start running water. Make sure the water is warm so the cat won’t put up a fight.
There is as far as possible not to show the trace of the application of wire, wire wound flower stems should be wrapped with green or brown tape, in order to cover the trace of the use of wire, in the use of wire modeling can make the drooping flower head raised, and the flower head reinforcement, for herbs and other flower material soft plants, can make the stalk straight. Wire shearing method: if you want to cut the wire, the wire should be straightened and then cut, can not bend the wire, fold and then cut, otherwise, the wire cut is not straight, will bring a small hook, affect the use.
- Cages are more often used for large dogs, which are very powerful. So choose a dog cage must be strong, otherwise the dog can easily break the cage and escape.
- And the role of wire mesh in the exterior wall plastering if from an Angle of anti-falling method, the effect of anti-cracking is relatively small, because of the azimuth problem; And about the external insulation system is used in the brick veneer, as for the role should also be anti-drop followed by anti-cracking, so we should choose the grid 10×10×0.6, these are some experience selection, the conversion of the grid comes from the national standards of steel wire mesh, the selection of steel content of the grade conversion.
Customers in the order of wire mesh will often shop around, most customers are in comparison with manufacturers to give the product price, the company tells you, do not blindly compare the price. To standards, production technology, manufacturers and other factors lead to different prices.
- 4, galvanized can be used zincate galvanized or chloride galvanized process, should use appropriate additives to meet the requirements of this standard coating.
Post time: 14-11-22Galvanized iron wire has good anti-corrosion and anti-rust ability, so it can be prevented from being used in some outdoor guardrail or fence, especially on handicrafts, handicrafts are also of great use, galvanized iron wire, the surface is not easy to rust and oxidation. Now many hardware manufacturers produce iron wire, and iron wire is very easy to rust, if you need to use in outdoor or humid places, generally customers will require the use of galvanized iron wire equipment to give the wire a layer of zinc, the thickness can be determined according to user requirements.
Cattle net in outdoor use for a long time will inevitably show rust corrosion, this time the use of cattle net life depends on the maintenance of the product is not in place, we all know cattle net if a long time exposure to the harsh environment, the service life will be greatly reduced. How long does a normal cattle net last?
One is to do a good job of galvanized wire packaging, to avoid bumping, to ensure the integrity of the zinc layer;
Post time: 22-02-23- Galvanized wire can be seen as iron wrapped in carbon, when extinguished, the surface is comparable to shallow carbon can contact with oxygen, produce carbon dioxide gas, will wrap it in iron (this is a molten state) radiation in. The more carbon there is in the galvanized wire, the more likely it is to spark. The iron-encased carbon is like dynamite in a dynamite bag, blowing the iron away from time to time.
The temperature of large roll galvanized wire should be controlled at 30 to 50℃ during electroplating. Because the chloride ions in the bath are very corrosive, quartz glass heaters are generally used. Continuous production does not need heating, but needs cooling. Cooling can be in the groove side row thin wall plastic pipe, through the flow of tap water cooling, can also be used as a titanium pipe temperature control device.
Some customers may not immediately use the blade barbed rope when they buy it for retail and some are temporarily not used for site construction. At this time, customers need to follow up the characteristics of the blade barbed rope for storage. Because they are afraid of the rain, so there is no need to say more, and the surface of the packaging is more afraid of the sun, so it is not recommended to prevent the outside of the blade thorn rope will lead to the woven bag become lost effect, resulting in the exposure of the internal blade thorn rope affect the later use.
Galvanized electric welding net is widely used in industrial production, agriculture, engineering construction, transportation, mining and other processing and manufacturing industries. Such as machinery and equipment protective cover, animal guardrail, pot flower guardrail, window fence, safety exit guardrail, poultry cage, egg basket and home office food industry basket, paper basket and design decoration. It is suitable for general engineering building wall, pouring concrete, multi-storey building, etc., which plays an important structural role in the thermal insulation system. In the construction of the building, the thermal insulation board of hot-dip galvanized electric welding grid is placed on the inside of the outer mold of the wall to be concreted. The external thermal insulation board and the wall are one kind of live, and the thermal insulation board and the wall are integrated into one body after the removal of the mold.
- D, coating adhesion; The zinc layer of the plating parts should be firmly combined with the base metal with sufficient adhesion strength, and will not fall off or bulge after the hammer test.
- 4. Rinse the foam off your cat thoroughly.
- The precautions of galvanizing wire in galvanizing are introduced in detail! When galvanized wire is galvanized, it is generally necessary to pay attention to the following problems: the duration of the protective effect of galvanized wire is greatly related to the thickness of the coating. Generally speaking, in the dry main gas and in indoor use, the thickness of galvanized wire galvanized layer only 6-12 μm “, and in harsh environmental conditions, galvanized wire galvanized layer thickness needs 20μm “to B height up to 50μm”. Therefore, the environmental impact should be considered when choosing the thickness of galvanized layer. Galvanized wire in galvanized, pay attention to the above problems, can be well galvanized, to ensure the quality of galvanized wire.
Iron products are common metal products in life. Iron products appear everywhere in our life, but there is a big problem in using iron products. Iron products will rust, and when rust occurs, it will affect the use and appearance of iron products. Adding non-metallic coating: clean, dry and coat the surface of iron and steel products with a layer of protective materials, such as oil, mineral grease, rust-proof grease, plastic and lacquer.
- In order to adapt to the living habits of different birds, ornamental cages can be roughly divided into two types of bird cages, namely cereal and insectivorous cages. Cereal bird cage with canary cage, yellow bird cage, wenbird cage, bird cage, hydrangea cage, insect-eating bird cage with thrush cage, chin cage, myna cage and so on.
When galvanized wire out of the light plating should be carried out light treatment. The bath temperature of galvanized wire should be controlled well. Galvanized wire, also known as hot dip zinc and hot dip galvanized, is an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. It is to immerse the steel parts after rust removal into the molten zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to play the purpose of anticorrosion.
Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
