PVDF(fluorine-carbon) Coating

PVDF(fluorine-carbon) coating :made of fluorine carbon resin, pigment, ester solvent, after high temperature roasting and baking, the paint is solidified to dry film with super weather resistance. PVDF coating also can be classified as traditional PVDF and nanometer PVDF coating.

A.Traditional PVDF Coating, with KYNAR500 PVDF, two or three times for coating and baking, has good properties of anti-acid, anti-alkali and is durable in atrocious weather and environment, keeping 15 years no unwonted fading. In view of these facts, we recommend this panel applied for external wall cladding.

B.Nanometer PVDF Coating, which different with traditional PVDF is the clear coating. It contains nanometer element, which can protect panel from pollution, Because nanometer has self-cleaning effect, It easy to get rid of dust and pollution by raining or water.

Q:How to calculate the weight of strips with the weight of aluminum coil known?
Thickness*width*length=weight/density, length=weight/(density*thickness*width).Ps: Keep unit the same.
Q:How does aluminum ingot be processed to aluminum coil (aluminum sheet)?
This depends on what aluminum ingot is. Small ingot needs to be casted into big one by putting into the melting furnace, and then be rolled to aluminum coil through rolling mill.
Q:How to deal with too much aluminum powder in aluminum striping?
Currently, there are bag dust-removal system and water dust-removal system. The former is very popular with enterprises because of low maintenance cost, accounting for over 90%. But the problem is the dust accumulation because the ventilation and dust removal systems are not produced in strict accordance with the standard. For example, controlling wind speed does not meet the requirement; ventilation and dust removal system does not meet the requirements of explosion-proof, including the set of pipes, series and parallel connection, the choice of dust removal system, the spark detection and extinguishing measures.
Q:Is the aluminum coil with damaged side still useful?
The side of tire, also called side wall, is the thinnest and most fragile. Side wall damages can be divided into swell and scratch. The swell is often caused by external force (The car is trapped in pit or on curb when you are driving fast). It can cause the cord thread break so that the rubber of the tire side wall cannot be fixed and tightened. The size of the swell is often as big as that of an one-yuan coin and will become bigger as the traveling distance increases. Under such circumstance, it is recommended to replace the tire. Scratch is usually caused by bad roads or debris on the road. It is recommended to replace the tire if the scratch in the side wall is obvious and the cord thread break. If the front wheels have such damages, the tire should be replaced as soon as possible (Because the steering, braking and driving is mainly based on the front wheels.). If there is no spare tire on site, change the front damaged tire with the rear tire and drive to an appropriate place.
Q:How to calculate the wall thickness with the gross weight of aluminum coil known?
Gross weight*density=volume volume÷(aluminum sheet *width)=thickness
Q:What’s the standard of tensile strength and ductility of aluminum coil 3003?
Detailed description can help resolve problems quickly. Performance and status is a related. As aluminum coil is usually semi-hard, the tensile strength is greater than or equals 150, ductility is greater than or equals 12.
Q:What’s the difference between aluminum tile, coil and sheet? Why?
Wood pallet is often used, which is easy to transport and can ensure the safety of products.
Q:Why there is always impression and indentation on the backup roller of aluminum coil rolling mill with 4 rollers.
Perhaps there is something wrong in the position controlling the working roller tilt and bend positive and negative convexity, making the working roller out of order and rubbing against the backup roller.
Q:What is color aluminum coil?
The base plates are all aluminum, but the surface has been colored.
Q:Why does the end face of aluminum coil have grease spots?
Process one without coolant to see whether there are spots. There is a layer of alumina membrane on the blank face of aluminum coil, which will react with basic coolant when heating through processing.
