What is the meaning of C in 13.5 * 1500 * C in plate specifications?
In front of the thickness and width, C said length, according to need to determine.
Matt sheet and high light plate difference
My home is to use a paint-free board, its surface is a layer of broadcast film, a kind of plastic things, the surface of the speaker useful to this material, this panel is easy to be painted, and can not repair, it is thin, bad. But not easy to deformation, and no paint, no paint taste, relatively environmentally friendly, but inside is a thin MDF, not durable. Easy to mold, my home on the mold, especially the wet weather.
Which master please teach about aluminum alloy doors and windows under the material calculation method? Flattened; push-pull can be the best example. Thank you!
High pressure water jet cutting High-pressure water jet cutting is the use of high-pressure cylinder to the ordinary tap water pressure to 250 ~ 400MPa, and then through the hole diameter of 0.15 ~ 0.35mm gem nozzle jet to form a speed of 800 ~ 1000m / s high-speed jet, and in the water arrow Add the right amount of sand used to cut all the hard and soft materials. The advantages of water cutting are: almost no heat when cutting, the product is not thermal deformation, can guarantee product size accuracy; slit narrow and smooth cutting surface, without secondary processing, improve production efficiency; water cutting can be good To solve some high melting point, alloy, composite materials and other special materials, cutting processing. However, due to water knife and water jaw lag and incision bevel phenomenon caused by the tolerance error, for more than a certain thickness (40mm or more) or high precision parts, the use of waterjet processing and can not achieve the best results.
What is the difference between acrylic and resin plates?
Acrylic from English, the chemical name is abbreviated as: PMMA; PMMA, also known as polymethyl methacrylate, is made from acrylic monomer (pellet or liquid) MMA polymerization. Because the transparency is very high, can be as high as 93%, so it is also known as: plexiglass. Acrylic is not plastic, because the plastic is PVC collectively, from the use of acrylic terms: can be divided into: advertising materials, decorative materials, crafts materials. Resin board, also known as eco-resin plate (Ai Hao), chemical name: PETG PETG is a non-crystalline copolyester, PETG commonly used comonomer is 1,4-cyclohexanedimethanol (CHDM), all known as polyethylene terephthalate-1,4-cyclohexane Dimethanol ester. It is the product of polycondensation of terephthalic acid (TPA), ethylene glycol (EG) and 1,4-cyclohexanedimethanol (CHDM) by transesterification. Compared with PET, -cyclohexanedimethanol comonomer, with the PCT more than ethylene glycol comonomer, therefore, PETG performance and PET, PCT is very different. PETG sheet has outstanding toughness and high impact strength, the impact strength is modified polyacrylate 3 to 10 times, and has a wide processing range, high mechanical strength and excellent flexibility, compared to PVC transparency High, glossy, easy to print and have an environmental advantage.

Simply put, that is, from the hot-rolled plate through the bell-type furnace or continuous annealing process, into a cold-rolled plate, the actual change is the physical structure of iron atoms, making it easier to bend, punching and other mechanical process The Cold rolled plate is only a basic plate inside the plate, after galvanizing, it becomes a galvanized sheet.
What are the plates for the bathroom?
Generally do not have to do the plate, are made of glass and brick

What kind of plate is the decoration with the density board?
In daily life, people commonly referred to as the MDF, but also can be called fiber board, it is made of wood fiber, or other plant fiber as raw materials, plus urea-formaldehyde resin, or other appropriate adhesive made of man-made sheet. Since it is called MDF, then it must have a certain density. Therefore, according to their density, we can divide the MDF into three categories: low density board, medium density board and high density board. In view of the MDF texture is soft, and the impact resistance is relatively strong, but also relatively easy to re-processing, so abroad, MDF is a very good material making furniture. However, because the domestic demand for high-density board is much lower than the international standard, therefore, the quality of China's MDF should also be further improved.
