黑白铁加工有哪些特点?

来源: 日期:2019-09-17 发布人:admin

  黑铁和白铁,字面意思就是黑铁和铁。而济南黑白铁艺加工是一个小车间,主要加工普通的铁艺和镀锌铁板之类的东西。他们称普通铁为“黑铁”和镀锌铁(俗称雪花铁)“白色铁”。
  Black iron and white iron literally mean black iron and iron. Jinan black and white iron processing is a small workshop, mainly processing ordinary iron and galvanized iron plate and other things. They call ordinary iron "black iron" and galvanized iron (commonly known as snowflake iron), "white iron".
  黑铁又称不锈钢,是济南一种黑白相间的铁。不锈钢的原色是黑色的,我们看到银不锈钢是经过加工抛光的。对于不锈钢,我们称之为黑铁。不锈钢的耐腐蚀性能随着含碳量的增加而不断降低,因此,大多数不锈钢含碳量较低,大不超过1.2%,而有些钢的Wc(含碳量)会低于0.03%(如00Cr12)。不锈钢中的主要合金元素是铬(铬),只要铬的含量达到一定的值,钢就具有耐腐蚀的功能。因此,不锈钢的普通铬含量至少为10.5%。济南黑白铸铁加工
  Black iron, also known as stainless steel, is a kind of black and white iron in Jinan. The primary color of stainless steel is black. We can see that silver stainless steel is polished by processing. For stainless steel, we call it black iron. The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, up to 1.2%, while Wc (carbon content) of some steels is lower than 0.03% (for example, 00Cr12). The main alloying element in stainless steel is chromium (chromium). As long as the chromium content reaches a certain value, the steel has the function of corrosion resistance. Therefore, the common chromium content of stainless steel is at least 10.5%. Processing of Black and White Cast Iron in Jinan
  镀锌铁皮俗称镀锌铁皮。将干净的铁片浸在浓缩的液态锌中制成。相比之下,锌确实是活泼的,但在富含CO2的潮湿空气中,可以形成一层碱性碳酸锌:4Zn+2O2+3H2O+CO2→ZnCO3。3Zn(OH)2这层碱性碳酸锌膜比较致密,也可作为维护膜使用,避免了锌的内部不再继续氧化。
  Galvanized iron sheet is commonly known as galvanized iron sheet. Clean iron sheets are dipped in concentrated liquid zinc. In contrast, zinc is indeed active, but in the humid air rich in CO2, a layer of alkaline zinc carbonate can be formed: 4Zn+2O2+3H2O+CO2_ZnCO3. The alkaline zinc carbonate film 3Zn (OH) 2 is compact and can be used as a maintenance film to avoid the internal oxidation of zinc.

  假设一旦破坏镀锌层在未来,攻击电化学腐蚀,因为锌比铁更生动,将锌原电池消极攻击氧化反应和遭受损失,铁被维护和马口铁相反,马口铁攻击电化学腐蚀,因为铁比锡更加生动,铁是保持在里面。但是假设锡层被固定在一起,因为它是原电池的阳极,锡会使铁腐蚀得更快。
  Assuming that once the galvanized layer is destroyed in the future, attack electrochemical corrosion, because zinc is more vivid than iron, it will passively attack oxidation reaction and suffer losses of galvanized primary batteries. Iron is maintained and, contrary to tinplate, tinplate attacks electrochemical corrosion, because iron is more vivid than tin, and iron is maintained inside. But assuming that the tin layer is fixed together, because it is the anode of the primary battery, tin will cause iron to corrode faster.
  镀锌铁特点:镀锌铁表面不易生锈。俗称铅铁、锡铁。为什么这么难生锈?这是维修的效果层表面的铁,这与假设涂层受损,还可以形成一个铁锌原电池,作为阳极,铁和铁所维护的专用阳极的阴极维护原则。
  Characteristics of galvanized iron: The surface of galvanized iron is not easy to rust. Commonly known as lead iron, tin iron. Why is it so difficult to rust? This is the iron on the surface of the repair effect layer, which is related to the assumption that the coating is damaged, and can also form an iron-zinc galvanic cell as the cathode maintenance principle of the special anode maintained by the anode, iron and iron.
