Q: What is the difference between splicing and fingering of wood panels? Specifically, thank you!: The ends of the two woods are made of teeth, and the middle is made of glue, and it is also understood that the two woods are crossed together like a finger. Splicing refers to the side of the board for gluing. Under normal circumstances, the stitching is used to access the width, the finger is used to make long. Need to stitch the wood does not require special processing, and finger of the board need to be processed at the end of the board into a tooth shape.

Q: How is the environmental standard of the plate defined?: According to China's environmental standards, according to the concept of formaldehyde emission limit, the limit of formaldehyde in the plate is divided into three levels, namely E2 ≤ 5.0mg / L, E1 ≤ 1.5mg / L, E0 ≤ 0.5mg / L The Plate to meet the E2 level standard, that is, E2, E1 and E0 class plate can be called the green sheet, but because of consumer awareness of environmental protection, and now the market more common E1 or even E0 grade plate. ???? E0 standard is to allow formaldehyde in the plate, but can not exceed 0.5mg / L, which is the highest upper limit; the lower limit should be the highest content of wood aldehyde itself (wood self-aldehyde content is generally 0.12mg / L-0.04mg / L) That is the lower limit is 0.12mg / L. ??? "Zero formaldehyde" is the choice of non-formaldehyde, the production process does not produce aldehyde; on the environment of the production staff do not bring any pollution and injury. From this we can give "zero formaldehyde" plate so that the free aldehyde in the plate is less than or equal to the content of the wood itself (usually 0.04mg / L-0.12mg / L). "Zero formaldehyde" sheet and E0 is not the same thing, "zero formaldehyde" sheet principle that higher than the E0 level.

Q: Very grateful to xiaokaikaiya, AAA forgot to hide 8, 100 plate _ business; the origin of this issue I elaborate: late this year I ride a motorcycle to go to China, Sichuan, Tibet, the new line, two cars and equipment a total of about 900 I will be equipped with two side boxes and a trunk, the three boxes are 7075 material, a single box with stents are about 8 kg, three boxes a total of about 24 kg, due to The vehicle carrying equipment is too heavy lead to tire wear serious, more than 14,000 km new tire completely worn out, so I want to use the new material to re-create the side box, on the one hand to reduce the weight, but the material strength can not be reduced, because the motorcycle reversing When the side box can be used with the front bumper to form an effective protective space, the protection of the human leg and vehicle protection is very significant! The ??? Do not know whether the above statement is clear, there are problems you can contact.: 7075 aluminum alloy is Al-Zn-Mg-Cu super-hard aluminum, 7075 alloy is the late 1940s has been used in the aircraft manufacturing industry, is still widely used in the aviation industry, ultra-high strength deformation of aluminum alloy. It is characterized by good plasticity after solution treatment, good heat treatment strengthening effect, high strength below 150 ℃, and particularly good low temperature strength; poor welding performance; stress corrosion cracking tendency; need to be covered by aluminum or other Protection processing use. Two - stage aging can improve the ability of alloy to resist stress corrosion cracking. In the annealing and quenching state of the plastic slightly lower than the same state of 2A12. Slightly better than 7A04, sheet static fatigue. Notch sensitive, stress corrosion performance is better than 7A04, of which 7075T651 state is particularly top grade, known as aluminum The best products, high strength, far better than soft steel. This alloy has good mechanical properties and anodic reaction, is a typical aerospace aluminum alloy material.

Q: Millennium mill plate is good or the new millennium plate is good: The new millennium is the king coconut group under the well-known domestic brands, fame may not thousands of years of large, it is not wasting thoughts on the minds of the mind spent on the quality of the new millennium is not a brand of goods factory specializing in the production of this brand, the other It is not to say, buy bad also buy an OEM goods you injustice injustice, anyway, we are all with the new millennium, on their own home watching the factory getting bigger and bigger, we believe that seeing is believing , Listen to the evaluation of the workers inside.

Q: Jin Liyuan plate quality how: My home decoration is used in this brand, the quality that is not say ~ ~ carpenter help ~ ~

Q: What is the material in the timber? What is the plate?: The specifications of the material is the buyer's request to the wood processing into the required specifications such as 2 cm long 2 cm wide and 1 meter long and other special specifications, the buyer bought a little bit in the processing can be used, the plate is we often see the mountain wood processing Into a piece of one

Q: What are the characteristics of spruce plate?: Strong pine wood] to answer your questions about wood! ?? Spruce, also known as European white pine, its fine texture straight, material stability, not easy to deformation cracking, strong resistance, while easy to planing, planing the surface after the smooth, bright, can absorb paint and colorants, and Easy to glue. It itself has a soft color, fine texture and natural texture is very natural into the furniture design, showing a simple original beauty. Spruce has a variety of advantages and uses a wide range, has been hailed as "the Nordic green diamond." ????? Main use: furniture components, housing ceiling, decorative keel, floor, shutters, cabinets, wall panels, musical instruments, organ tubes, boxes, wooden barrels, joinery, cutting wood, sleepers, building structural materials, Bridges and other timber.

Q: Are plates p2 and e0 almost?: In the purchase process, as long as optimistic about the level of formaldehyde release board on the line. E0 best, E1 times, E2 has been rarely used. Southeast wood manufacturers have super E0 board, formaldehyde release even less, but also by the United States California certification p2 plate. CAPB P2 level is higher

Q: The advantages and disadvantages of the plate frame, what brand is better?: Material: high-tech plastic memory sheet manufacturing. Design: tailored for the majority of fashion and the pursuit of quality students. Features: simple and neat design style, the overall performance of a stable one Face, using the right color process. Emphasis on mirror legs On the three-dimensional changes. Accessories: mirror feet and feet perfect fusion, like totally natural, the lens shape is very personalized. Performance characteristics: a certain degree of flexibility, when a little hard to bend or tighten after relaxation, shape memory sheet will be restored. Cut the frame with a cellulose acetate sheet. The characteristics of the plate is not easy to burn, relatively light, almost no exposure to ultraviolet light and color, hardness greater gloss better, durable, easy to heat processing, style is more beautiful, easy to wear after deformation.
