Q:Whether abandoned aluminum foil has recovery value?
Preparation of the main raw material utilization bauxite, aluminum hydroxide, zeolite spent catalyst, there are a wet preparation method, electrolysis method or the like. Some scholars believe that the economic value of waste aluminum foil having a high recycling. He used the scope of waste aluminum foil prepared PAC optimal conditions and water purification through experiments.
Q:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
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: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:What's the aluminum foil flexible air hose?
Generally speaking, aluminum foil flexible air hose is used in dust collection and exhaust in bathroom.
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:Who knows the price of phenolic-aluminum foil composite board?
Aluminum phenolic composite board ; One-sided phenolic composite colored steel board/ single phenolic composite colored aluminum foil board for center air-conditioning; A long-term supply for good quality phenolic foam thermal insulation board/phenolic aluminum board/insulation phenolic board; Double-sided extruded aluminum foil board/insulated board/ wind board; Phenolic aluminum foil insulation board/central air-conditioning ventilation board/floor heating panel; Phenolic aluminum board/ phenolic insulation board/phenolic aluminum composite blast pipe board/ fire-resisting blast pipe board/flange parts
Q:Why does volatile test need aluminum package?
