Product Description:

Cans cover (ring) pre-coated plates
First, the raw materials
Aluminum lid and pull the main substrate of aluminum from the southwest andNanshan Aluminum, the use of aluminum-magnesium alloy 5182H19, 5052H19. Itsproducts in the normal substrates of manganese and magnesium components addedto increase the tensile strength and elongation. Han and the lotion by theGerman food-grade chrome HD agent, the United States PPG epoxy phenolicpackaging coatings, and high-end DOS oil
Second, applications
Division I professional production of DOS card and aluminum cans with a coatingfor cans of the lid and pull the coated aluminum is widely used in beverage,beer, rice pudding, tea, cigarettes, cans and other products packaging. U.S.imports of food ash using electrostatic spray wax, cut by large waves, transverseshear, longitudinal easily processed into the system covered the pre-coatedaluminum manufacturers. Depending on the system covers equipment can makeweight and volume of different specifications to meet customer requirements.
Third, the application prospect
Cans of food packaging as lightweight, unbreakable, easy to carry transportcharacteristics, cans packaged foods will gradually replace the glass packagingfood. As China'seconomy continues to strengthen, improve people's living standards, consumptionwill be more and more cans, cans will be growing timber. Therefore, cans withthe amount of pre-coated aluminum coil will be more and more broad prospects.

Appearance

The surface of the pop cans cover coatingdoes not allow defects such as air bubbles, scratches, missing coating,over-burning, oil spots, stains, streaks, color, piebald, roller printing,embossing, periodic prints, chemical liquid etc which impact users.

Each coil allowed a joint which does notallow loose layer or dislocation, the joint can only be overlapped, which needto make the mark in the end, and each batch coil of joint  is not morethan 10% of the total number of coils.

Q:Is it unsafe to use deodorant with aluminum?
Aluminum, okorder.com/
Q:Opinions wanted. Carbon or Aluminum?
carbon is normally lighter but i would prefer the high end aluminum
Q:Foshan where there are high-quality aluminum and aluminum rolls for sale?
If you know where to use, or what are the requirements of the words I can occasionally recommend you manufacturers give you, because I am in this industry!
Q:Why is aluminum nitrate not an ionic bond?
You have the advantage here. As far as I know, the compound is ionic with one Al^+3 ion and three NO3^-1 ions. There have to be 3 negative ions to balance the charge of +3 on the aluminum ion to make a neutral formula unit
Q:Why doesn't aluminium oxide dissolve in water?
It does dissolve, but only slightly. It has a solubility of about 0.0001 under atmospheric pressure, it doesn't dissolve because the aluminium is extremely strongly bonded to oxygen, so it can't dissociate very much at all. If you want to dissolve aluminium oxide, you should use an alkaline solution.
Q:Can an aluminum and Fluoride bond be created by boiling fluoridated water in aluminum cookware?
i would say yes because ions are released from most things when heated
Q:It is harmful for a budgie to take a bath in a aluminum pie tin?
poisoned by what? if aluminum was poisonous why are aluminum foil and aluminum cooking utensils legal?
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:can a person absorb aluminum through the skin, by handling solid aluminum?
Pure soft shiny aluminum develops a thin tenacious layer of aluminum oxide that retards further oxidation (unless worn off). The outer layer of skin is dead horny matter that resists penetration by metal atoms. However, some people do develop allergies to metals and perhaps metals dissolved in sweat (acids?) may get through to live tissue. Handling aluminum may not have been proved harmful but skeptics likely will take less chances.
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.
