Dogs of all ages seem to love to touch their noses with humans and other animals. In fact, dogs touch their noses as a way of socializing, just like humans shake hands and hug when they meet. But dogs don’t touch every human or every animal. They pick and choose who to touch. If they don’t like you or don’t know you at all, they won’t touch your nose. However, adult dogs will touch almost every puppy’s nose, and they will not only touch the puppy’s nose, but also smell it.
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.
There is also in the use of places, blade thorn rope is generally installed and used for the border, walls, prisons and so on, and galvanized thorn rope is in the orchard, fence livestock and so on a large area of installation, although the use of large, but not as high as the use of blade thorn rope and grade, so this is the main reason for the high price. Finally, for the blade barbed wire, the general installation site has high requirements for the protection level, so the quality of the product is also relatively high. But the ordinary galvanized barbed wire has relatively low requirements for the quality in the processing process due to the casual requirements at the installation site.
1, zinc pot workers to resolutely do duty and responsibility. Do not leave the post without permission, always observe the change of steel wire galvanized layer, and according to the analysis of the results, master asbestos block gap friction need how long to press, replace the pressing face; Adjust the working face; Until the four faces of the asbestos block are used up, maintenance workers continue to use it after repair when necessary to reduce the consumption of asbestos block.
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.
The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.
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, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.
After annealing, the extension rate of galvanized wire is increased, making the product more soft and increasing the scope of application of galvanized wire. After electric galvanized hot galvanized, electroplated copper and other widely used screen production. Building reinforcement binding with galvanized wire mesh braided with the first after plating, plating and other methods, after treatment of galvanized wire mesh or steel wire mesh, has good corrosion resistance, oxidation resistance characteristics, can be used in construction, petroleum, chemical, aquaculture, garden protection, food processing and other industries reinforcement, protection and heat preservation.
Corrosion usually metal corrosion has three types: physical, chemical corrosion and electrochemical corrosion, and corrosion depends on the chemistry of the metal itself and the organizational structure, still have relationship with the surrounding medium, such as wet environment than dry environment is easy to rust, more less than the impurities of impurities is easy corrosion, high temperature conditions than under the condition of low temperature corrosion, etc. After knowing these, we can effectively prevent the corrosion of the dip plastic six side wire mesh, prolong the service life of the product.
Zinc is a silver-white metal, brittle at room temperature, soluble in acid and alkali, known as amphoteric metal. Pure zinc is more stable in dry air, and small in humid air or water containing carbon dioxide and oxygen. A thin film layer of basic zinc carbonate will be formed on the surface, which can delay the corrosion rate of zinc layer. The corrosion resistance of galvanized layer in aqueous solution of acid, alkali and sodium chloride is relatively strong. It is also not resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in Marine atmospheres; In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded.
