Product Description:

Printing industry left the age of “Stereotype and Branding”, and step into the era of “Photo and Electronics”.Aluminum lithographic support material provides a strong sustaining for this renovation in printing industry.

It will be mostly used in making lithographic support, which is a new type of material among the printing industry for automatic and presswork.

Features:

1.Pre-painted galvanized steel coil is light , beautiful and with good anti-erosion performance.

2.The service life of hot dip galvanized steel plates based color coated steel plates is much longer. As the organic coating covered on the zinc layer has isolation effect, can prevent the steel from rusty better.

3.PPGI can be processed directly, it provides a new raw material for the construction, shipbuilding, vehicle manufacturers, furniture industry.

Applications: Widely applied for construction, home appliance, furniture, transportation and other industries.If you are interested in our products, please do not be hesitate to let us know. We will be happy to give yo a quotation upon receipt of your detailed requirements.

Q:What are the compositions of aluminum coil coating?
The common compositions are crylic resin, solid inorganic filler, different pigments, flatting agent and so on.
Q:What should pay attention to transporting aluminum coil?
You must ensure the good property of the aluminum coil.
Q:Can kerosene lubricate and cool aluminum coil when continuous punch?
Yes, because water and oil are not solute, but they will emulsificate.
Q:How much fluorocarbon and polyester paint should be used in production of aluminum coil and aluminum-plastic panel?
The theoretical calculation is very complicated and far from actual result. In general, the manufacturer knows how much area and how thick their products can be painted.
Q:How to calculate the dosage of paint for aluminum coil coating? If the weight is 1 ton, the density 2.71 and the thickness 0.12mm, how much paint is needed?
Coating surface area S*0.12(thickness)*ρ(density) / solid(paint solid)=actual paint consumption brush and roller paint: 100% spray paint: calculated value*70%
Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
Q:What are the effects of casting temperature on ductility of aluminum coil?
The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
Q:What does it mean to slice aluminum coil by decoiler machine?
The operating procedures of decoiler machine: 1, Select appropriate aluminum coil according to production work order requirement to be processed, paying attention to the thickness, width and material of aluminum coil. 2, Put the aluminum coil into the coil loading car with traveling crane and inch the car into the uncoiler. The aluminum coil and decoiler machine should be in the same direction. Hold the aluminum coil down with leading head, and open the auxiliary bearing. 3, Turn on the shovel head, and inch the uncoiler to lead the aluminum sheet into the leveler. Adjust the leveler according to the thickness and width of aluminum sheet to ensure the flatness. 4, Turn on the front gap bridge and back gap bridge in control main platform, inch the leveler to lead aluminum sheet into re-leveler. Adjust the re-leveler to ensure the flatness of aluminum sheet. Put it into the shear gauge and plate shearer. 5, Take back the front and back gap bridge. Inch the plate shearer to cut off the sheet head and shear the aluminum sheet according to production work order. Check the first sheet to see whether it meets the quality standard and whether there is defect in flatness, length, diagonal, and surface of aluminum sheet. If it is qualified, turn on the conveyor. Put the aluminum sheet holder on the pallet. Adjust the pallet according to the width and length of aluminum sheet. Input quantity and length on the control main platform. Then turn on the auto control to produce automatically. The production process can be observed at any time. 6, If there is aluminum coil left, unwind, package and put it into storage in reverse steps.
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:What are the production processes of aluminum coil and what are the functions of various industrial furnaces in the production of aluminum? The more detailed, the better. Thank you! Points!
General steps are as follows: melting - hot rolling - cold rolling - annealing – shearing – straightening – punching
