Urgently purchase magnesium alloy plates 25 500 500, 12 pieces. Who can tell? Thank you.

Qingdao Dexingsheng Metal Materials, specializing in magnesium alloy materials, often get goods with them, the quality and quality are also OK, you can ask. Generally, they have spot inventory, all of which are large slab blanking, and it is estimated that there should be the size you want. You ** said that Guangdong Lao Kong introduced that.

Look at the plate not only to look at the front, but also to look at the side.

Panels are available in most construction markets, mostly solid wood and composite.

According to the positive ** analysis of your post, it looks like a compound. Composite panels are mainly multi-layered, granular, etc. (look at the side should be able to separate).

Do you still want planks.

The amount of felling per year is x.

From the meaning of the title: (5 4) 20a 4x(5 4) 20 4x 4a Ling y (5 4) 20, then lgy 20(lg5 lg4) 20(1 Li Huiqing 3lg2) 2

y 100,100a 400x 4x 4a x 8 33a, so the annual felling amount cannot exceed 8 slag 33a

Set all timber for a total of a cubic meter.

The timber transported at one time was 3 a-40 cubic meters.

The timber for the second shipment was 3 5(3 a-40) cubic meters.

The third shipment of timber was 400 cubic meters.

3 a-40 + 3 5 (3 a-40) + 400 = a, solution: a = 720 Answer: all timber is 720 cubic meters.

Hello, this is actually ash The scientific name is ash wood, which is a very common tree species, and it is very common There are ash wood in several large sail log wholesale bases across the country! You will find out if you go online and travel to the rest of the Internet! Grinding accompaniment.

Connoisseur [Mr. He Guangning] will answer for you! If mine is helpful to you! Please be prompt! Your recognition is the biggest motivation for me to answer the questions! Thank you.

"Effect Network" has a detailed explanation. Selection points:

1) When the wood is spliced and glued, the radial cut timber is spliced and glued with the radial cut timber, and the chord cut timber is spliced and glued with the chord cut timber to prevent deformation or cracking during use.

2) In general, the same tree species or wood with similar properties should be selected for the same use occasion.

3) In order to avoid warping deformation or cracking caused by dry shrinkage and wet expansion, the wood should be dried to make its final moisture content meet the requirements of the specified purpose, for example, the moisture content of dry sawn timber for furniture shall generally not be higher than 12%, and the moisture content of building structure timber should be less than 15%. The final moisture content of general wood should also consider the use environment of wood products, which is consistent with the wood equilibrium moisture content of the wood products use environment, and the balanced moisture content of wood in China's provinces (autonomous regions) and municipalities directly under the Central Government is shown in the "Sawn Timber Drying Quality" GB T6491-1999.

There are hundreds of common ones, and the main thing is not to buy the bad ones.

How to see if the wood is good or not.

We have also encountered the troubles of magnesium alloy plate processing before, and Huaiyan has not been satisfied with the processing effect. Now I use Metco's MB133, and the processing effect is quite satisfactory. Anyway, the customer accepted it. Semi-synthetic.

I hope mine can help you, thank you.

Plant-based lubricants are used to protect the processing material to the greatest extent. Unist is pretty good.

Analysis: After being cross-cut into 2 sections, the surface area is increased by square decimeters compared with the original, which means that two bottom areas are added, so the bottom area can be calculated.

Solution: Base area: 2 = square decimeters.

Volume = base area * height = cubic decimeters.

Cylindrical timber cross-section, truncated to form two cylinders, the surface area of the two cylinders is the bottom area of the two cylinders, regardless of the ** cross-section. Because the total height remains the same. Therefore, find the volume of the original cylinder: that is, the surface area of all 2 = the area of the bottom of the original cylinder, and the volume = the area of the bottom of the original cylinder 2 meters.

So the volume of the original cylindrical timber: cubic decimeters.

The surface area has increased by = 2 r = square decimeters.

r = 2 dm.

2 meters long = 20 decimeters.

Original volume = r * height = cubic decimeters.

square decimeter square decimeter.
