Performance and usage

PVDF coated aluminum coils are specially processedthrough the technics of roller coating and baking with precise paints fromBECKER INDUSTRIAL COATINGS in Sweden andTHE VALSPAR CORPORATION in USA.The main material of PVDF is polyvinylidene fluoride resin; the utmost negativecharacteristic of the Fl atom can form a very strength high powerful Fl-C bond.Moreover, with the special symmetry molecule structure, the products are ofstrong weather resistance performance, anti-ultraviolet performance, super longdurability and anti-corrosion performance, which can maintain very bright andglossy color even serving for 20 years in outdoor environment. Attributing tothe abrasion resistance and impact resistance and flexibility, our products areof excellent mechanical processing performance. PVDF coated aluminum coils arethe highest priority of choice to high class aluminum composite panels, and itscomposite products are widely used in airport, exhibition center,administration center, star hotel and other symbol building.

Color of Card
Our PVDF coated aluminum coil is made offluorine carbon resin, pigment, ester solvent after high temperature roastingand baking. The paint of this PVDF coated aluminum coils are solidified to dryfilm with super weather resistance. PVDF coating also can be classified astraditional PVDF and nanometer PVDF coating.
A. Traditional PVDF Coating, with KYNAR500 PVDF and two or three times forcoating and baking, has good properties of anti-acid, anti-alkali and isdurable in atrocious weather and environment, keeping 15 years no unwontedfading. In view of these facts, we recommend this PVDF coated aluminum coilsare applied for external wall cladding.
B. Nanometer PVDF Coating, which different with traditional PVDF, is the clearcoating. It contains nanometer element, which can protect panel from pollution,because nanometer has self-cleaning effect, it is easy to get rid of dust andpollution by raining or water.

Color Match
For custom' color requests, we can deal as following:
1. Supply a physical sample of custom color. A color sample on metal ispreferred. If other, it is also acceptable. But the color matching rate may benot good as color on metal.
2. New color sample is usually offered by our paint supplier in 5-7 days,special color should be in 7-10 days.
3. Upon receipt of color sample, please approve in writing as soon as possible.Once you approved, we will arrange purchasing and production.
Note: Color difference maybe occurred in different production batch, soit is suggested all panels are placed in one order for same project. And keepsame direction as arrow on protective film when installing to avoid any colordifference by vision.

PE (polyester) Coating
PE
(polyester) coating:Using high molecular polymer as monomer and addition of alkyd, this PE coatingmethod of our color coated aluminum coil is an UV-resistant coating. It can beclassified matt and glossy according to coating gloss. The compact moleculestructure makes paint surface luster and smooth, which assures good printing onthe PE coated aluminum coils surface. With a warranty of 8-10 years for weatherresistance, it is specially applied for internal decoration and sign board.

Color Match
For custom' color requests, we can deal as following:
1. Supply a physical sample of custom color. A color sample on metal ispreferred. If other, it is also acceptable. But the color matching rate may benot good as color on metal.

Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
Q:How to polish aluminum sheet to be bright?
you must do some protection work, or you will fail once aluminum contacts air. Aluminum sheet is easy to be oxided and volatilized.
Q:how to connect copper pipe and aluminum sheet?
welding!
Q:does aluminum sheet has a function of magnetism isolating?
copper sheet is better.
Q:what's the oxidation method of positive pole on the surface of aluminum sheet?
Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
Q:Which kind of glue can bond two pieces of aluminum sheets?
you can use tin welding.
Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
Q:what's the difference between zinc sheet and aluminum sheet?
Only the zinc sheet reacts after adding concentrated nitric acid in drops ,zinc is amphoteric.
Q:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
generally, all things in Europe needs ROSH EU's requirement, mainly detect the plumbum. ROSH detection is conducted by third party institution, and its report is also provided by the third party.
Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
