Q:What's the raw materials of high-precision alumimium foil?
It's the high-precision aluminium. Aluminium foil is produced by constant rolling and annealing.
Q:What's the difference between colored aluminum and coated aluminum foil?
According to your description, I suggest you adopt acid pickling process. The basic principle is that aluminum foil will conduct oxidation reaction after being put into the acid to change the color of aluminum foil, which will meet your requirement. The color belongs to aluminum itself not painted by people! This method can get many colors like golden and milky. Different acid ratio will lead to different color.
Q:What temperature needed to keep the aluminium foil spray lacquer having the adhesive force
To judge the adhesive force of oil paint of aluminium paper,we should heat the double paint formulations and the curing agent of the lacquer to 80 degree and 150 degree.
Q:Which products are aluminum foil applied on?
First, the flexible foil Flexible packaging is the use of soft composite packaging material bag container, flexible packaging technology has greatly improved mechanization and automation level of the food and beverage industry to speed up the modernization and socialization process of people's eating habits. Flexible packaging not only with moisture, fresh effect, but a variety of printable patterns and text, is an ideal material for modern commercial packaging. With the improvement of people's living standards, as well as flexible packaging foil much room for development.
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:who knows the ceiling technology of aluminum sheet?
Construction technology of ceiling aluminum sheet: (1) firstly check keel’s quality, the straight shape and uniformly forced state of boom, control the keel’s gap within 500mm, reduce the gap according to design requirement under humid environment. The lower surface of keel is smooth without a sense of bearing down, main device is closely connected with accessories, it can be bound after being confirmed qualified.(2) we should break the board along the cutting line and ensure the margin of cutting board straight and square without any chipping or arris defect. (3) while placing and fixing the board, we can place edge of aluminum-plastic panel(encapsulated edge) in the vertical direction of supporting keel, there is a phenomena of hanging. Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. You can start from a plate angle or middle position, and don’t place them at the same time. Slab joint should be straight and in the same width, without break joint. (4) in the process of joint, Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. And the butt joint should be stagger, the butt joint can’t be connected on the same keel. When you use doubling plate, the joints of the second layer board and the first layer board can’t be connected with the same keel, double-deck gypsum board should be staggered joints.
Q:Why continuous annealing aluminum foil production process?
Annealing is to make aluminum foil becomes soft, soft, malleable aluminum foil like, if not annealed, rather hard to pull off aluminum foil and other unexpected problems likely to occur in the rolling process. So after each rolling aluminum foil should make another annealing process, so as to ensure that the aluminum foil in the following rolling process smoothly.
Q:How is the welding performance of 3003 aluminum coil?
3003 aluminum coil, a kind of rust-proof aluminum, belongs to AL-Mn series alloy. With low intensity (slightly higher than commercial purity aluminum), it cannot endure heat treatment, so cold processing is adopted to increase its mechanical property: high plasticity in annealing and semi-cold hardening, low plasticity in cold hardening, good corrosion resistance., good weldability and bad machinability. It is mainly used for low load part in liquid or gaseous medium requiring high plasticity and good weldability, such as fuel tanks, gasoline or lubricant conduit. It can also be used for liquid containers and other deep drawing small load parts made by deep drawing. Aluminum wire can be used to make the rivet.3003 aluminum sheet has good formability, weldability and corrosion resistance. It is used to process parts which require good formability, corrosion resistance and weldability and lower intensity than 1xxx series alloy, such as such as kitchenware, food and chemical products processing and storage equipment, groove and tank to transport liquid product, pressure vessel and pipe processed from thin plate, cooling fin, make-up board, photocopier rollers and ship material.
Q:Why are the aluminum coils sticky after annealing?
There is oil or the annealing time is too long!
Q:Can aluminum foil isolate wireless signal?
Aluminum can nearly isolate all wireless signal, but it should be wrapt tightly. The shielding effect is also related to frequency.
