With the improvement of people’s living standard, pet raising is becoming more and more common. Pets also need a comfortable environment, so pet cage is an ideal choice for pet raising. Dogs are loyal friends of human beings. They will accompany you all your life and protect you until you die. Raising small animals can bring comfort to lonely old people; Patients who receive visits from animals can improve their depressed moods and even relieve pain. Families with pets add joy and cohesion; Companion animals usually form familial bonds with their owners.

Annealing wire is widely used mainly because it has a good elasticity and flexibility, in the annealing process can be a good control of its hardness and softness, it is mainly made of iron wire, more commonly used in the construction industry tie wire use. When the wire factory is in production, the annealing wire will be processed according to the performance of the material, and its hardness will be changed according to the different demand, which can make it have more advantages, reduce the consumption of metal and reduce the cost of production.

Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.

A pet carrier can be used as an indoor and outdoor pet house. The dog cage is equipped with a fixed food basin and drinking water, and the foot plate pet cage rubber pad has bayonets on four sides to be collated. According to the cage size can be splicing, cutting, disassembly is convenient, easy to clean, can solve the puppy in the ordinary cage foot clamping problem, prevent the puppy in the development of adverse reactions. The dividers are breathable and comfortable, and can be used as heat shields for pets in summer. A puppy with small feet that does not hold its feet or pinch its feet.

We compare the difference between galvanized welding net and other welding net by introducing in detail, and write the following to introduce its material: Galvanized welded wire mesh is made of low carbon wire, through automation of fine precision machinery equipment spot welding processing after forming, selection of disposal of the appearance of zinc leaching technology, produce practice British standard, with smooth surface neat, uniform layout to consolidate, the function is good, even if some sections or accept pressure also won’t attack lax appearances, it is the strongest anti-corrosion function in iron mesh, Screen mesh is iron use one of the most widely network class, excellent anticorrosive makes its popularity in the breeding, sucking the neat surface, increased the look and feel, can play will be decorating effect, this feature makes it reflected in the mining industry, because the select material of low carbon high quality material, make it unique iron mesh not usually have flexibility, Concluded that it is used in the process of plasticity, and then can be used for the deep processing of hardware technology, disorderly wall swing, underground leak-proof crack, light net body, make this cost is much lower than the cost of iron screen, more can understand its economy, benefits. Galvanized welding net can be used as poultry cage, egg basket, channel fence, drainage tank, porch fence, rat net, mechanical protective cover, livestock and plant fence, grid frame, etc. It is also widely used in industry, agriculture, construction, transportation, mining and other occupations.

The welding core is the metal core of the electrode. In order to ensure the quality of the weld, there are strict regulations on the content of various metal elements in the weld core. In particular, there are strict restrictions on harmful impurities (such as sulfur and phosphorus), and the quality of the weld core metal should be better than that of the base metal. Arc welding cannot be carried out on a smooth rod without a coating. This is because the arc stability is very poor, splashing is very large, and the weld is not well formed. After long-term practice, it is gradually found that the performance of the electrode is greatly improved by coating the welding core with some mineral raw materials (i.e. electrode coating). (1) Ensure stable arc combustion, so that the welding process is normal. (2) Using the gas produced after the drug skin reaction, protect the arc and the molten pool, prevent the harmful gases in the air (such as nitrogen, oxygen, etc.) from invading the molten pool, such as these gases will cause cracks and pores in the welding material, so that the welding can not achieve the ideal effect. (3) After the drug skin is melted, slag is formed, which covers the weld surface to protect the weld metal, make the weld metal slowly cool, help the gas escape, prevent the generation of pores, and improve the structure and performance of the weld. (4) After melting, various metallurgical reactions will be carried out, such as deoxygenation, sulfur removal, phosphorus removal, etc., so as to improve weld quality and reduce alloying element burning loss.

With the increasingly extensive use of hook mesh, the method of bridge rail is also different. The height of sidewalks or seatbelt outer railings should not be lower than 1.10 metres. The net distance between railings should not be greater than 140 mm and horizontal bar rails should not be used. The planning of the hook mesh is necessary to be safe and reliable, the bolt should be installed on the basis of the railing, its strength should meet the requirements of the standard.

Zinc is a silver-white metal, brittle at room temperature, soluble in acid can also be soluble in alkali, known as amphoteric metal. Pure zinc in dry air is more stable, in humid air or containing carbon dioxide and oxygen water is small, the surface will generate a layer of basic zinc carbonate based thin film layer, it can delay the corrosion rate of zinc layer. The corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride is stronger.
