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: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:What do the two items (COIL:873347 HEAT: number) on the label of the raw material of aluminum coil stand for?
COIL means aluminum coil and HEAT means heating, so together they mean hot rolled coil.
Q:How many companies have used aluminum coil?
Too many. All the companies who make the aluminum products you have seen in daily life have used it. So it is hard to explain.
Q:How much does it cost to use fluorocarbon paint for aluminum coil roller coating?
Fluorocarbon paint can be divided into fluorocarbon paint for exterior wall, aluminum fluorocarbon paint, metal fluorocarbon paint and steel structure fluorocarbon paint according to usages. It can also be divided into national standard product and non-national standard product according to industrial standards.
Q:How much is aluminum-plastic panel with the 0.155mm thick aluminum per ton?
The price is around 17000 yuan per ton, but you need to take the surface effect into account
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:What are the compositions of aluminum coil coating?
Resin, pigment, auxiliary and solvent.
Q:What is the common color of aluminum coil membrane?
The blue transparent membrane is the most common.
Q:Will the surface of aluminum contact water if the aluminum coil falls into water?
That depends on how tight the aluminum coil is. If it is very tight, aluminum will stick together, thus no water can get in.
Q:Is there aluminum coil of 44mm wide and 0.40mm thick?
The common width of aluminum coil is 1000mm or 1220mm. If you want 0.4mm*1000MM aluminum coil, you can strip 0.4mm*1000MM aluminum coil.
