What is the packaging standard of stainless steel foil?

Packaging standards for ss coils with a width of 2<width<10mm:
When the width is 2<width<10mm, a carton ring is used between the first stainless steel foil roll and the second ss foil roll to prevent the two ss foil rolls from squeezing and bumping. Each narrow material ss foil inner layer uses a plastic ring. The outside is packed in a carton.
Wrap the outer tray cover with a carton ring. The bottom ss foil roll is separated from the tray by a carton ring. Finally, put the whole into a wooden box and add foam particle filling. (See picture for details)
Packaging standards for ss coils with a width >10mm:
Wrap it with moisture-proof canvas paper, put it on a pallet, and put it in a special wooden box that is fumigation-free, and add foam particle filler. (See picture for details).

Where to buy stainless steel foil?

As an individual, when you need to purchase stainless steel foil less than 1 kg, you only need to go to online platforms such as Amazon to purchase directly.
As a factory, if the raw material you need in ss foil, you need to understand the ss foil you need to purchase: hardness (or tensile strength), width, thickness, surface requirements, etc. Or you can tell me your application, yaoyi has professional engineers to find suitable ss foil for you.
If you have purchased ss foil before, but you don't know its parameters, you can send me samples of stainless steel foil. We have professional testing equipment to test the composition and hardness of ss foil for you.

 

How to produce stainless steel foil?

The size range of precision stainless steel strip is different from that of conventional stainless steel foil. It refers to cold-rolled ss foil with special ultra-thin specifications. The thickness is generally between 0.05-0.5mm, and it is called ss foil below 0.05mm. Such products require high quality and difficult process control. It is extremely difficult to produce the ss foil. For example, 4 rolling passes and 24 hydraulic pressure are required to produce a ss foil with a thickness of 0.02mm.

Usually, one stroke requires six times of 180 tons of hydraulic pressure, and each time you have to check whether the steel surface has color difference and whether it is flat.

In the production process, the ss foil is added with CU and TI, thereby reducing the solubility of sulfides mainly composed of Mn and S in acidic liquids, reducing cavitation and cracking, making Yaoyi stainless steel foil with good protection Corrosive.

 

How to weld stainless steel foil?

Only brazing can be used. That is, vacuum brazing or MIG brazing can be welded. Vacuum brazing should use brazing paste and brazing material, and put them into the vacuum furnace for welding after installation;MIG brazing is welding with low melting point brazing wire, but for stainless steel foil, there will be greater welding distortion.
For Example:Material: WEWELDING 88C cooperates with WEWELDING 88C-F low-temperature welding.
Tool: Choose WE53 multi-hole spray gun
The argon arc welding is beautiful. However, the speed is slow. In recent years, the popular cold welding of thin plates is more beautiful, does not need to be polished, and is more difficult to speculate. The speed is slower and slower, so it cannot replace argon arc welding (welders must be fast if the quality is possible). Stainless steel also belongs to steel, of course, many methods can be used. Handle welding in arc welding, ordinary gas shielded, pulsed arc welding, laser welding, friction welding, resistance welding, submerged arc welding, etc.

Is it healthy to use stainless steel for cooking or tin foil?

The main function of tin foil is better heat transfer, wrapping food, allowing food to be heated more when grilled, and easier to cook. It is not that tin foil is healthier than stainless steel.

Mineral oil, the processing aid used on the surface of the tin foil during the manufacturing process, will volatilize when heated. Is it harmful? 

Take a look at the introduction: The base oil extracted from petroleum by physical distillation is called mineral oil. The processing flow is in the crude oil refining process, after fractionating useful light substances, the remaining bottom oil is then refined (Called the old three sets (solvent refining, ketone benzene dewaxing, clay supplement refining)). The main two steps are solvent refining to remove non-ideal components such as aromatics and solvent dewaxing to ensure the low temperature fluidity of the base oil.

 

The production process is based on physical processes, without changing the structure of hydrocarbons. The base oil produced depends on the content and properties of the ideal components in the raw materials; mineral oil cannot be cleaned of impurities during the refining process, so the flow point It is higher and not suitable for cold zone operations; so, mineral oil base oils are subject to certain restrictions in nature. Main purpose: used in the manufacture of washing powder, synthetic detergent, synthetic petroleum protein, pesticide emulsifier, etc.
