Processing of some details of color steel plate:
1. Repair method for rivet leakage: Apply sunlight single-component waterproof glue 4 times, with a thickness of about 1.5mm and a diameter of about 50-60mm. The next time you apply the above paint, it will not stick to your hands, and the diameter of each application Both are larger than the last, thicker in the middle and thinner all around so the rivets don’t leak.
2. Leakage method of color steel joints:
1. One-component waterproof glue with a width of 60mm and a width of 2000PA can be applied to both ends of the seam, and the 20mm adjacent to the seam should not be applied.
2. Non-woven fabric, width 150mm, attached to waterproof glue coated with 2000PA sunlight.
3. Brush the non-woven fabric or glass fiber cloth 3 times. When brushing, the width of the second time is 50mm than the first time, and the thickness is about 1.8mm after the first time.
Pay attention to some details. Generally speaking, color steel plate will not have much problem, so color steel plate is the best building material in building materials.
3. Understanding and Suggestions on the Procurement of Color Steel Plates for Construction
The use of color steel plate is generally divided into three categories: construction, transportation, and home appliance shell, and color steel plate for construction occupies a large part, followed by the home appliance industry, and the proportion of traffic is relatively small.
Color-coated building panels are generally made of hot-dip galvanized steel sheets and hot-dip galvanized steel sheets, which are mainly processed into corrugated cardboard or sandwich panels conforming to polyurethane. They are mainly used in roofs, walls and doors of industrial and commercial buildings, such as factories, airports, and warehouses. And freezers, home appliances color plates generally use galvanized plates and cold plates, which are often used in refrigerator shells or large air-conditioning shells in enterprises, freezers, bread machines, furniture, etc. The substrates used for transportation are mostly galvanized plates and cold plates. Used in oil pans, automotive interior parts, etc.
Generally speaking, the color-coated board for building has higher strength and better corrosion resistance than the color-coated board for home appliances. This is because the color-coated board for construction is usually a part of the stressed structure, and its working environment is located in a complex outdoor environment. The service life is relatively long, so high strength and corrosion resistance are required.
4. Different uses and classification of color steel plates
Color steel plate is a material used to build temporary fences in the process of urban construction. Many families’ houses will leak water, and sometimes the roof will be pasted with color steel plates. According to the composition, color steel plates are divided into two types: single-layer and composite color steel plates.
At present, the application of color steel in my country is mainly concentrated in three aspects. The market utilization of color steel can be roughly divided into three parts: construction, home appliances, and transportation. Among them, the construction industry accounts for a large proportion, the home appliance industry is second only to this, and the transportation industry only accounts for In a small part, the performance of the single-layer steel plate has a protective effect, but its heat retention is obviously reduced. Most of the color steel plates used in the building system in my country are composite samples of thermal insulation.
