Product Description:

Our glass wool panels are made of high qulity pure melting silica,which can bare of over 350 degree and have very good performance.Turning 90 degrees after cutting, assure the fiber direction perpendicular to the sheet so as to increase the strength. Spraying the high-intensity fire-proof adhesive to the surface of the core and the sheet, ensure that it won’t be cracking after a long time. On the other hand, we use the polyurethane side sealing technology which greatly improves the insulation waterproof performance and general quality.

Q:What equipments are needed to produce aluminum foil bag?
It depends on whether you directly use composite aluminum foil film or raw materials that aren't well composited. If you directly use composite aluminum foil film, you may need dividing and cutting machine and bag machine. If you use raw material,you may need printing press, compound machine,dividing and cutting machine and bag machine.
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:How to prevent oxidation of aluminum coil?
Aluminum roll casting machine is rolling through, pull bends process for the conduct of the shears of metal products. 1 aluminum storage environment should be dry, bright, well-ventilated, non-corrosive climate.
Q:The thickness of aluminum foil bag is 30 silks. Is it thick or thin?
It's very thick. What's more, 30 silks should be the thickness of two sides with each side shares 15 silks.
Q:The thickness of aluminum foil.
The purity of aluminum foil and the pure aluminum are higher than the lithium battery. the material of thickness of 0.1mm is called foil,and now the thickness of aluminum foil is 0.01mm.
Q:How to remove the oxide layer in the aluminum foil with a chemical process?
Generally, we adopt the method of alkali corrosion to remove the oxide layer on the surface of the aluminum foil.The purpose of alkali corrosion is removing the oxide layer on the surface of the aluminum foil. (Note: Technological process of the method is as follows: under normal temperature, 20% nitric acid; the process parameters is about 0.5 minutes. Pre-degrease--degrease--rinsing--rinsing--alkali corrosion--rinsing--rinsing--bright dipping--rinsing--rinsing--pure rinsing. The purpose of bright dipping is to remove surface residual black ash after alkali corrosion.Temperature:50-60 degrees; time:0.5-1 minutes.The purpose of degreasing is to remove grease on the surface of the aluminum foil.The process parameters is 0.5-1 minutes. You can use acid to wash it.
Q:The advantages and disadvantages of waterproof aluminum film and aluminum foil
me for use shorten to five years. it is influenced by the environment and quality.5.if the same roll takes this method of coverage, the combination property is nearly the same.
Q:What need to use aluminum foil?
1.Flexible package. Flexible package is a bag container made from composite packaging material. It is the ideal packaging material of modern commercial which is not only has functions of moisture-proof and fresh-keeping but also can be printed on many patterns and words. With improvement of people’s live standard, there is still a great space for the development of aluminum foil for flexible package. 2.Medicine foil. Aluminum foil for medicine package mainly includes the easy open bottle cap of water aqua and injection as well as medical PTP aluminum foil. Since PTP aluminum foil is moisture-proof, convenient to carry, safe and health, it is widely applicable to the international medicine industry. 3.Composite aluminum foil for automobile.
Q:Aluminum foil and fold thickness difference is caused by what?
Chatter marks mean shear foil surface periodically. Generating oscillation marks two reasons: one is due to the formation of roll grinding cycle in about 10 ~ 20mm; the other is due to the oil film is not formed continuously rolling vibration often generated in a speed range, a period of 5 ~ 10mm. The root cause is the lack of chatter marks film strength, generally can be used to improve lubrication to eliminate.
Q:What defects may causes through the aluminum foil roll?
All the rolls can cause surface damage factors, can be formed on the aluminum foil rolling harm. Because aluminum foil rolling roll surface finish high, slight gloss surface unevenness will affect its status. Periodically clean mill, mill kept clean, to ensure the normal operation of roll clearance, roll change periodically, reasonable grinding, it is to ensure a uniform surface substantially aluminum foil rolling conditions.
