Preparations for flood control and flood control

　　Flood control has become an important issue since the rainy season. Flooding baffle can effectively solve the problem of flood control, and it is a very important tool for our flood control. But what are the factors that determine its cost, I believe we are not particularly clear.

　　1, waterproofing baffle, pillar material costOutsiders may think that this is just a roughness of stainless steel and magnesium aluminum alloy. In fact, there are many models of stainless steel and magnesium aluminum alloy. Depending on the model, the metal composition is different, and the price and performance are completely different.

　　For example, there are 201, 202, 304 and 316 stainless steel. In the common 304 and 201, 304 stainless steel has a high nickel content, corrosion resistance and rust resistance are much better, so the price is quite expensive. Even with recycled waste (stainless steel scrap), 316 is more expensive.

　　2. Look at the overall cost of a flood control system in detailFor PCBS, good circuit design can greatly improve circuit efficiency and electrical performance. For the waterproofing baffle, the installation convenience of the design can see whether the product is shoddy, and the installation difficulty can also be seen from the location of the screw holes. But the anti-human design is hard to twist up and down with a wrench, hard to force.

　　3. Post-treatment cost of waterproofing baffleIt looks exactly the same, but it's also very watery. In aluminum alloy, there is nothing to do after a plate comes out, and there is nothing to polish. Regardless of whether the surface treatment is chemical oxidation or anodic oxidation, the wear resistance and hardness after anodic oxidation are better, but some factories directly omit these links in order to save labor.

　　In addition, the same height was designed. How many levels is the board divided into? Think multiple layers cost more than one? The original multi-layer waterproof plate between the need for waterproof sealant, cutting the plate for grinding also requires a certain operation.
