Q:Why can iron and steel stick with glue?
Iron and steel steel is an alloy of iron with C (carbon), Si (silicon), Mn (manganese), P (phosphorus), S (sulfur), and a small amount of other elements. In addition to Fe (iron), the content of C plays a major role in the mechanical properties of steel, so it is collectively referred to as iron carbon alloy. It is the most important and the most important and the largest metal material used in engineering.
Q:What's the difference between a spray plate and a colored steel plate?
Then the color, not the quality of the domestic coatings products, fully meet the demand, the high price of imported coating reduces the competitiveness of skin colour in the plastic film is still dependent on imports, lack of high-grade color coating thickness, functional, high strength, rich color coated plate. Therefore, the choice of color steel plate is relatively narrow, and basically are low-end products, but more convenient, you can buy directly!
Q:Must the welding between steel sheets be opened?
Not necessarily, very thin plate, no opening, but also guarantee penetration, but also through nondestructive testing
Q:What is the thickness of the paint board?
As a decorative wall painting board, the scale is greater, a 122*244*1.8cm UV paint board. The most common market in general is 15-18mm, one of 18mm's highest market share, in addition to 12mm, 9mm, 5mm thickness, if it is made, manufacturers generally have the ability to make 3mm-35mm between any thickness out.
Q:Can Q460C steel plate be used as Q235 steel plate?
The mechanical properties of the same structure require that the Q460C can reduce the thickness of the material used and reduce the weight of the structure without changing the mechanical properties, without reducing the strength of the base metal and the service life of the workpiece. Reduce the number of welded structures.High strength steel instead of ordinary low carbon structural steel is the current trend.
Q:Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
No minimum, no maximum, no requirements, what kind of plate can be welded, but the welding method is not the same as welding equipment.
Q:What is the difference between the zinc plated color guide and the profiled steel sheet?
The difference between the zinc plated color guide plate and the profiled steel plate is as follows:1, plated aluminum plate is pure aluminum 99%, and aluminum zinc is generally divided into 5% zinc plating and 55% aluminum zinc.2, zinc plating in zinc plating on the basis of the development of slowly, and 5% and 55% refers to the aluminum content.
Q:How do I print the steel plate?
In fact, the printing mode called "stencil printing", is a kind of porous printing, first use the typewriter in special Lazhi typing, or a stylus paint word pictures, and then let the wax paper attached to ordinary paper, ink in the painted pattern, through hole type or writing, and printing to the following the common paper.
Q:How can steel plates with a thickness of 1MM be welded?
1mm steel plate is best made by spot welding or flash welding, for example, electrical welding will cause plate deformation
Q:What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water stopping principle: the water stop bar is expanded by water absorption and then squeezed with concrete to stop the void.Construction technology: the stop bar is square long strip, and parallel lap method is adopted when connecting. No break point can be left in the middle. Construction units in order to facilitate, often like to use the water bar, concrete pouring in the completion of the pressure on the wall concrete pouring surface, or reserved groove, two times mosaic.Good and bad analysis: simple construction, less investment, relatively economic. But there is no water stopping effect and the water stopping steel plate is good. There are many unforeseen problems during the construction process. One is that the reinforcing bars are not close enough to be laid. Two is the time is too long, moisture absorption expansion, the impact of the effect, especially in the rainy season, air humidity, rainfall, water retention is worse. Three construction joints are not smooth, poor contact. Usually, this method is not ideal for stopping water. For example, when the water stop bar is installed, the retaining of the groove is too large to be fixed effectively; the small inlay is not in place; when the concrete is poured, the utility model is easy to shift under the action of the concrete buoyancy.
