- 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:TR-90 cp pc plastic glasses frame difference, as well as what is the material sheet! Physical properties how?
- TR90 spectacle frame surface lubrication, the density of 1.14-1.15, on the saline will float, than other plastic glasses frame light, about half of the weight of the plate material, nylon material is 85%, can reduce the bridge of the nose, the burden of the ear, suitable for young people . It is very resistant to wear, good chemical resistance, solvent resistance, weather resistance is good, not easy to burn, high temperature. And it is memory of the polymer material, anti-deformation index 620kg / cm2, not easy to change because TR90 material Eyeglass frame elasticity, toughness, easy to break, strength, no rupture, so it has sports safety. And it is very resistant to impact: more than 2 times the nylon material, ISO180 / IC:> 125kg / m2 elasticity to effectively prevent In the movement due to impact on the eye damage. No chemical residue release, in line with European food-grade materials requirements.
TR90 material than other pc, cp and other frames material is much more expensive, and the production process is also more stringent, so TR90 glasses frame price than the other to be several times more expensive.
CP: refers to propionic acid frames
PC: refers to the plastic frames, made of polycarbonate
Material: The material is made of high-tech plastic memory plate. Ingredients: Most of the current sheet metal components are acetate fiber, there are a few high-grade frame is propionic acid fiber, while the acetate fiber sheet is divided into injection molding and pressing Type, injection molding is the name of the mold is made of water, but most of the current is to suppress the processing of sheet metal glasses in terms of the origin of the plate in France and Italy, the plate is better, Japan is also quite good, many high-end sheet glasses Based on these high-quality sheet, and therefore more reliable quality.
- Q:How to calculate the amount of plate is how to use the cabinet?
- Basically divided into two types: First, the front projection area, the second is the expansion of the area plate.
See the following:
Front projection area: the person standing in front of the cabinet to see the side of the cabinet area, for example: wardrobe width of 2 meters high 2.4 meters, its area is 2 * 2.4 = 4.8m², which is its area;
The expansion of the plate area: the cabinet is made after each of its plates are calculated out of the area together with the area;
Note: If you want to know how many boards a cabinet, the need for an experienced woodworking master to know, if more accurate, you must wait for the pattern of the cabinet out to be more accurate.
- Q:Computer tables, two kinds of sheet: particleboard / melamine board MDF / fiber board which is better material?
- Computer table of the plate, it is recommended to choose particleboard / melamine board. It is not recommended to use MDF
Reason: 1. The former high environmental protection factor 2, the former moisture resistance is good 3. The former than the latter grip nail force is good, easier to fix.
- Q:Willow eucalyptus wood and pine which is good
- Although it is a relatively cheap wood, but the average price of pine is higher than the rice eucalyptus.
Willow eucalyptus wood, because of its appearance (grain, scar), and the material itself is less valuable. Willow eucalyptus rarely used directly into furniture, and exposed wood finishes. And more as a blockboard and other man-made plate sandwich core material, and then blockboard all kinds of artificial wood paper, "camouflage" into a variety of good wood, and then made of furniture.
Of course, this "camouflage plate" country is allowed, but the state also clearly stipulates that the blockboard is not a solid wood, the use of blockboard production of products can not be called solid wood products.
- Q:Three thousand square plate is good?
- I think you still have to believe that a sub-quality goods, choose the plate, can not just look at the price, but also depends on the quality, reliable quality and stability to deal with home decoration. So I can only say that the home decoration or the need for an environmentally friendly space so I think the election three thousand square or value for money, specifically to see your needs!
- Q:What are the plates for the bathroom?
- Generally do not have to do the plate, are made of glass and brick
- Q:Guangzhou red cotton plate and ordinary moisture board What is the difference
- My home wardrobe is made of red cotton plate, there is no pungent taste.
- Q:PCB board material how to identify
- PCB board material identification, can be carried out from the following four aspects:
(1) dimensional stability
In addition to pay attention to X, Y axis (fiber direction and horizontal direction), but also pay attention to the Z axis (plate thickness direction), due to thermal expansion and contraction and heating reduction factors easily lead to silver plastic conductor fracture.
(2) electrical and water absorption
FR-1 is better than FR-1 and XPC in terms of dimensional safety, electrical and water absorption, so that the insulation of the insulator in the absorbent state is reduced, so that the metal is moved under the potential difference. Production of silver through-hole printed circuit board, to use special FR-1 and XPC paper substrate.
Copper plating through the copper hole is a continuous crystal, there is a very good ductility, not like silver, carbon ink in the thermal expansion and contraction, easy to interface separation and reduce the conductivity.
Silver and copper are metal materials, easy to oxidize and restore the phenomenon caused by rust and migration phenomenon, due to the difference in potential, silver than copper in the potential difference between the trend of prone to silver migration (Silver Migration).
Circuit board name: circuit boards, PCB board, aluminum plate, high frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit boards, ultra-thin circuit boards, printing (copper etching technology) circuit boards. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production and optimization of the fixed circuit.
- Q:1, if the nose is a metal support, you can hand to the middle of breaking off.
- 1, if the nose is a metal support, you can hand to the middle of breaking off.
2, if the whole into a whole is plastic, nasal care will not be deformed. It must be attached to the lens and the lens between the screws too loose, two mirror feet breaking too open, you can tighten the screw tight.
3. If you have a small wedge, you can tighten the screws on both sides of the frame, it is recommended not to break the glasses to the inside, because the improper grasp of the words easily broken
In addition to the optical shop can have a special person will help you tune, of course, is generally selling glasses.
