PE(polyester) Coating

PE(polyester) coating:high molecular polymer as monomer and addition of alkyd, is an UV-resistant coating. It can be classified matt and glossy according to coating gloss. The compact molecule structure, makes paint surface luster and smooth,which assure good printing on the panel surface. With an warranty of 8-10 years for weather resistance, it is specially applied for internal decoration and sign board.

2 Usage/Applications of PE Coated Aluminum Coil/Sheet

Our company's PE Coated Aluminum Coil/Sheet have been widely used in the fields of construction and decoration(garage doors, ceiling etc.), electronic appliances, lighting decoration, air-condition air pipe, sanwich panels and drainage, etc.

Q:Why aluminum tubes can not be used as lightning rod materials?
There must be some wind resistance. In addition, the aluminum pipe is not high temperature bar. The common lightning rod is made of stainless steel or pure copper.My factory has the production of various types of lightning rod, contact the user information
Q:What ion is corrosive to the aluminum tube?
Too much, mainly is the strong oxidizing ion such as hydrogen ion, iron ion, nitrate ion, permanganate ion and so on
Q:Which tubs are heated by aluminium tubes? The plastic feels unsafe
Plastic pipe heating at high temperature, it is prone to explosion, security is not high. Have you heard it is not SOFO Soffer, aluminum heating, very good security.
Q:How do you weld aluminum plate and aluminium tube?
Before determining and selecting the welding process for aluminium tubes and aluminium sheets, the following matters shall be determined:1. aluminum tube and aluminum plate metal material grade, according to your aluminum tube and aluminum plate material performance, joint use conditions and corrosion resistance, choose welding materials;2. aluminum tube and aluminum sheet metal properties;3. mechanical properties or strength, tensile strength and shear strength required for welded joints;4. welding joint working conditions, such as corrosion resistance.According to the above characteristics, choose the welding method for aluminum pipe and aluminum plate. At present, the main methods of welding aluminium tube and aluminium plate are:1. high frequency induction brazing: high frequency induction heating is used to melt the solder. The cost is low, and the use is convenient. At present, this process is used in many industries to braze the aluminum tube and aluminum plate;2. diffusion welding: generally used rarely, mainly for surface bonding;3. flame brazing: lower cost.
Q:How to bend the oval aluminum tube 10
Draw the ellipse you need on the ground. Look for a fixed point on the ground, a little bit bent
Q:How is the seamless pipe or tube seam identification for enlighten heroes?
Soak in a strong alkaline water for a while.
Q:What causes aluminium tubes to peel and blacken?
Whether the "anodic oxidation" (electrochemical oxidation), the pipe wall is not oxidized, or the internal oxidation of the pipe is not cleaned.
Q:How to solve the aluminum tube cutting,
Aluminum tubes have professional aluminum cutting pieces, and the speed is also related
Q:Where is the difference between aluminium plastic pipe and PPR plastic aluminium pipe?
The first two can be bent, the connector needs to use copper pieces. The latter can not bend, the straightness is pretty good, the connecting parts are made of double hot melt PPR parts, and the three can withstand the temperature for a long time to reach 95 degreesWhile the former two is different, RPAP5 is a high technology product butt welding, endurance is more uniform, the price is higher than the ordinary plastic pipe (welding), relatively RPAP5 butt welding aluminium plastic pipe, the effect is better than the other two kinds of tubes.
Q:Brass or aluminium tube for internal and external air conditioner?
Some manufacturers for the cost on the tubes, each also has been used before, Rui tubes, not how many years
