- Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
- Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
- Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
- Q:how to produce aluminium sheet circle?
- As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
- Q:How to solve the loose bonding of aluminum sheet and silica gel?
- you can use YH-840 to bond silica gel and aluminum sheet in small area, and it’s hard to tear and will have an effect of destruction and melting, transparent and environmental.
- 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:Could induction heating fuenace be packaged with aluminum foil as insulation material?
- It’s useless. Aluminum foil will generate eddy and emit heat after medium induction, which will reduce the thermal efficiency of medium frequency. Now I provide a method for reference only. Induction coil will be water cooling and is packaged by thermal cement and other materials. Use asbestos sheet and other materials to transform the both ends of induction heating coil as baffle which is mobile and convenient for load and unload. When steel tube is heated in the induction coil, you can put down the baffle to prevent large loss of heat, shorten heat time and improve heat efficiency. When the seamless steel tube is heated into setting temperature, you can open the baffle to conduct expanding process, and you don’t need to think about the thermorytic problem of steel tube in the expanding process. It’s important to shorten the time of expanding process. Baffle is used for heat retaining of medium frequency heating and extrusion forming in our factory. The method above for reference only.
- Q:what’s the difference of activated aluminum and aluminum sheet?
- 39,the thermal treatment of age hardening aluminum alloy, 40, lanthanum-praseodymium-cerium aluminum alloy and its producing technology, 41,casting method of cool room pack alloy without draft angle, 42, use the anti-corrosion alloy layer to protect the surface of nickel base alloy products, 43,saltless and inoxidizability remelting method of aluminum, aluminum alloy and aluminum waste...
- Q:Which kind of glue is best for bonding wood and aluminum sheet together？
- cm2, leather. 4, it’s durable and can endure 106 degree high temperature. Shock resistance, medium viscosity, enhancement mode, little smell, shock resistance, inactivated, hard for bonding, adhesives, wood brick. 480, little white sediment, bonding, acidity, 410。 415: filling the gaps, general furniture, high temperatuPlease operate in the environment of above 50 C, you can adjust according to the usage environment, the quick bonding of laminate , timber bonding and other parts，little white sediment, general type: 222286 belong to high solid, moisture content of bonding wood, shock resistance, low density materials, 6-10kg, bonding materials can conduct machining after having been placed for 24 hours: materials bonding. 3, 496, porous texture and humid environment: general type, coating uniformity of glue not over ±0, carpenter joggle. 6, medium viscosity, cyanoacrylate adhesive 401, good heat resistance, high density materials 12-18 kg packaging, Suitable for furniture. 414 (1) Formica, carpenter’s glue,
- Q:how to find 0.6mm waste strake of aluminum sheet?
- ask door and window maker for some strake.
- Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
- 60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
