Q: What is the difference between steel sheet and coil?: What is the difference between steel sheet and coil? 1, the factory specifications are different: The original flat: the steel out of the specifications have been cut out of the factory called flat. Plate is also the factory to board Q235ABCD What is the difference: B relative to A more than a constant temperature impact test! C temperature is 0 degrees Celsius D temperature is -20 degrees Celsius Q345B and C, D, E board with the difference between the same Q235 Q235B ordinary hot rolled steel. Yield at about 235 MPa, Q345A / B / C / D: low alloy (16Mn) yield at around 345 MPa ? Such as: Coil is the factory roll because the length is long to roll up with C said, such as: 2.75 * 1500 * C Tablet is the factory in the hot-rolled production line before the cutting plate stability of the specifications cut into a board, such as: 2.75 * 1500 * 6000 2, the thickness of the coil is generally 6mm below the plate; plate can be a variety of thickness of the steel plate, including the plate, the plate, thick plate.

Q: Density board and Orson board difference: Densboard (English: Medium Density Fiberboard (MDF)), also known as fibreboard, is made of wood fiber or other plant fiber as raw material, urea resin or other suitable adhesive made of artificial plate. According to their density, divided into high density board, MDF, low density board. Dust board due to the soft impact resistance, but also easy to reprocess, in foreign countries is a good material for the production of furniture, but because the country on the high density board standards than the international standard several times lower, so the density board in China, the use of quality Still need to be improved. Orson board refers to: Aosen card in the high density board. Mainly used to strengthen the floor of the substrate, but also for the furniture industry.

Q: There are children at home, very concerned about this problem. Thank you, you have bought, the brand called Sharon Dick this is quite good.: Solid wood furniture, formaldehyde content than the number of low-grade furniture, no specific indicators, generally much lower. Mainly affect the formaldehyde content of solid wood furniture is the paint part. Formaldehyde mainly from the glue, adhesives, paint and other processing to the part. House decoration because of formaldehyde and other factors caused by very hot eyes, the air is not clear and other conditions, solutions are: 1, ventilation, vacant for some time. 2, put in the house rotten apples, activated carbon, the effect is very good. 3, you can find a clear clear formaldehyde cleaning company. 4, put some flowers, you can absorb formaldehyde, but the flowers on the sacrifice. 5, the best way is to place 3 months, so that formaldehyde volatile.

Q: [Discussion] Why is the ultrasonic flaw rating of plates and forgings inconsistent? In the GB / T 6402-2008 steel forgings ultrasonic testing method forging the ultra-straight probe quality grade is divided into 4, 4 the highest requirements. Single point discontinuous flat bottom hole equivalent diameter ≤ 3mm and GB / 72970-2004 thick steel plate in the ultrasonic testing method provides the quality of steel plate is divided into four levels, one level requirements.: The standard is not the same batch of people to develop, certainly have different ideas, and the most important feature of this standard is copied to the EN10228-3 / 4, the basic is directly followed 1, the more important large forgings surface quality requirements are higher, the general surface area Flaw detection requirements than the heart of a grade as much as the specific requirements, depending on the use of the situation, the surface generally require a higher φ2 or φ3 equivalent 2, steel do not know 3, unqualified generally can not be used, but also hard to say, once we do Over 2 products, a test failed, the first make do with the user, the user test pressure no problem, and then use for many years, another qualified qualified, when the pressure test did not pass, spray a person oil

Q: PCB aluminum plate plate an oily size is how much: At present the conventional PCB aluminum substrate size of 400 * 1200mm, 500 * 1200,600 * 1200mm three

Q: Stainless steel sheet thickness of about 0.6 thick thick mm: In general, the thickness difference of stainless steel plate in a silk look, GB 0.5 actual thickness is 0.4,0.6mm thickness of 0.5, to 1.2mm above the stainless steel plate GB and the actual thickness of the gap between the larger, 2 silk is also possible, Mogo suggested that the landlord in the purchase of stainless steel plate, it is best to tell the other side you want the actual thickness, or the other side to bid price to stir up unnecessary trouble and misunderstanding.

Q: What is the difference between a sunglasses or a sheet of plastic?: Remove the sunglasses lens quality factors, the greatest impact on the price of sunglasses should be brand value-added and material caused by the different costs. Brand value added here is not discussed, this thing in the selection of sunglasses when the wise, can not tell a right and wrong. Then we talk about the material of the sunglasses frame. Compared to other materials, the use of sheet and plastic sunglasses frame on the surface is not see the difference. First of all, the plate frame is a memory function, if you buy the sunglasses mirror legs for you too tight or too loose, then you can adjust the mirror legs, straighten the bend is not a problem, but also inside and outside the bending Adjustment. If it is a plastic material sunglasses frame, a small adjustment does not work, it will automatically change back to the prototype, if a substantial adjustment - it will not change back to the prototype, because it has been broken ... Secondly, from the details, the frame of the frame to wear more comfortable, the basic will not appear discomfort. The plastic frame in addition to the overall structure is relatively stiff, is not conducive to the adjustment, the external paint may also be processed, there will be irritating smell. Finally, the frame of the frame will have steel (think of reinforced concrete, there are wood), durable. Plastic frame it, in addition to plastic or plastic, can be used to know how long days. So look at the appearance, you can not find the difference between these sunglasses.

Q: PCB board what: PCB substrate classification: 1, according to the different materials (the most commonly used classification method) ? paper substrate (FR-1, FR-2, FR-3) ? Epoxy fiberglass substrate (FR-4, FR-5) ? Composite Substrate (CEM-1, CEM-3) ? HDI Sheet (RCC) ? Special substrates (metal substrates, ceramic substrates, thermoplastic substrates, etc.) 2, depending on the resin Phenolic resin plate ? epoxy board ? polyester resin board ? BT resin plate ? PI resin plate 3, according to flame retardant performance to points ? flame retardant (UL94-VO, UL94-V1) ? non-flame retardant (UL94-HB grade)

Q: Some of the real use of solid wood, mostly pine and fir Kazakhstan, there are oak; and some with joinery, both from the service life and environmental protection point of view are their advantages and disadvantages, the cost is certainly a lot of difference. All the students, whether to give advice, 5 square meters of place want to do tatami, with solid wood and joinery cost and reason!: Wuliangmi platform plus tatami three thousand dollars it is recommended with blockboard solid wood easy to deformation plus geothermal finish
