Q:What is the difference between splicing and fingering of wood panels?
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:What is the difference between the addition of the plate and the Eo grade plate?
100% of the addition of non-formaldehyde-free plate and E0-type plate is different from the use of glue is not the same, E0-class plate is urea-formaldehyde resin, 100 wins and no use of non-formaldehyde plate is the use of formaldehyde-free US fourth generation MDI glue.
Q:How to degrease the wood
Under certain conditions, α and β - pinene will produce polymerization, the formation of yellow sticky material, so that it is fixed or associated with wood, such as aluminum chloride, heme, bleach, tested proved to be effective But the most commonly used boron trifluoride, the boron trifluoride alcohol solution applied to the surface of the plate, it will change the composition of the resin in the terpene, α and β - pinene can be converted into less volatile or Non-volatile, sticky, non-flowable fractions. Brush the boron trifluoride solution at a concentration of 26% on the surface of the resin to reduce the effect of resin bleed . But this method only Wood surface treatment, the wood within the terpene does not change, will still move to the surface of the resin and produce seepage, so this method is suitable for dry after the low moisture content of wood, in the wood before finishing.
Q:EO grade plate how is it? Does the dew river meet?
Up to now, no one in the world has been able to provide E0-level test reports because E0 is a standard rather than a standard for particleboard environmental protection. It can be said that it is in the concept of publicity. Mainly hope that consumers can pay attention to the environmental issues of sheet metal.
Lu River is the pride of our domestic enterprises! The
Because we have done a lot of cabinets cabinet products export business, we have done in the Procuratorate Lu Shuihe plate testing, the formaldehyde detection value is the unit content of formaldehyde content of 0.425ml, so, from a conceptual point of view, it The detection value is very environmentally friendly, worthy of our business and customer trust.
To believe: Chinese goods, no less!
Q:Aluminum alloy cutting method
Laser cutting is a new type of processing technology, has been widely used in metal cutting, glass cutting, sculpture and other industries. The laser is a kind of light, which is produced by the transition of atoms (molecules or ions, etc.), but it is different from ordinary light that the laser depends only on spontaneous emission only in the first short time, and the process is completely determined by laser radiation, So that the laser has a high coherence, high strength, high direction, laser cutting machine through the laser to produce laser, the mirror transmission and through the cluster mirror to the processed items, so that processed items (surface) by the strong heat and temperature A sharp increase, so that the point due to high temperature and quickly melt or vaporization, with the laser head of the trajectory to achieve the purpose of processing.
The advantages of laser cutting machine are: the processing of the workpiece without mechanical pressure, so cut out the product with high precision, no secondary processing; cutting speed, easy operation, high degree of automation; can cut any complex shape of the product, Cut, the model compression process is more preferred, although the processing rate is slower than the punching, but it saves mold costs, low economic costs. But for the thickness of more than 6mm aluminum alloy sheet, the use of laser processing, cutting effect is not good, and the equipment on the use of high environmental requirements, equipment failure in the service after a long time.
Q:What is the FR4 plate in the market and Tenghui VT-42B plate quite
Refers to the surface is FR4 light green, the middle of the black plate
Q:What is the width of the stainless steel sheet? What are the common widths?

Q:Home improvement plate which brand the best ah? Environmental protection best?
Like this kind of furniture plate material quality is good, only used to know, Fuxiang plate can be considered a very large enterprise in Hunan Province, and has been a good quality itself, you can personally go to their stores to see ah. Online question is also asked not to experience in order to understand!
Q:What is the good dressing wardrobe plate?

Q:What is the material of the deer river?
Now the dew river almost marks the environmental protection, consumers take this brand, manufacturers also say that the dew river, true and false, can Mongolia Mongolia, or recognize the good.
