Because their service is also a black-and-white iron processing service, this time, we need to let them operate and improve it. Because at this time, the service will enable them to realize their cost reduction. At the same time, the service for them in the whole obituary history will really have their own very high overall service quality improvement, and only in this way will the service, It can really satisfy customers.

　　黑、白鐵藝加工產(chǎn)品多用于空調(diào)通風(fēng)管道，能有效地進(jìn)行室內(nèi)通風(fēng)，各種排風(fēng)管道的生產(chǎn)安裝工作，各種異常通風(fēng)管道的效果更好。黑白鐵加工其實(shí)就是鍍鋅鐵，鍍鋅鐵只是大家熟知的一種。我們都知道，由于鐵在空氣中比較活躍，很容易與空氣中的氧氣發(fā)生反應(yīng)，所以鋅層被用來保護(hù)。雖然鋅不會與空氣中的氧氣相互作用，但在空氣中與二氧化碳相互作用，會形成一層保護(hù)膜，防止鋅的氧化。

　　Black and white iron processing products are mostly used for air conditioning and ventilation pipes, which can effectively carry out indoor ventilation, production and installation of various exhaust pipes, and the effect of various abnormal ventilation pipes is better. Black and white iron processing is actually galvanized iron, galvanized iron is only one of the well-known. As we all know, zinc layer is used for protection because iron is more active in the air and easily reacts with oxygen in the air. Although zinc does not interact with oxygen in the air, it interacts with carbon dioxide in the air and forms a protective film to prevent the oxidation of zinc.

　　在過去的兩年里，為了規(guī)劃黑、白鐵加工廠的規(guī)模，大量的小車間不得不關(guān)閉黑、白鐵加工廠。一是更好地規(guī)劃城市環(huán)境，二是規(guī)劃白鐵加工廠的規(guī)模和模式。正因?yàn)槿绱?，越來越多的小作坊黑、白鐵藝加工逐漸演變成今天的大型黑、白鐵藝加工廠或者說公司。黑白鐵處理發(fā)現(xiàn)鐵制品加工是一個(gè)前景廣闊,因此,該公司一直致力于鋼鐵產(chǎn)品的開發(fā),然后這些鐵產(chǎn)品到很廣,黑白鐵被應(yīng)用到各個(gè)領(lǐng)域,所以這種鐵現(xiàn)在仍然不是足夠能夠?qū)崿F(xiàn)很好的一步,這些鐵產(chǎn)品,是行業(yè)聚會,和我們的,盡管黑白鐵處理還需要不斷研究和開發(fā)新產(chǎn)品,黑白鐵,畢竟,雖然廣泛,但還有很長的路要走,畢竟我們要生活,黑白鐵穩(wěn)定性不是很好,所以,路還很遠(yuǎn)。無論是黑鐵還是白鐵，城市的建設(shè)都起著關(guān)重要的作用。

　　In the past two years, in order to plan the scale of China's black and white iron processing plants, a large number of small workshops have to close the black and white iron processing plants. The first is to better plan the urban environment, and the second is to plan the scale and mode of the white iron processing plant. Because of this, more and more small workshops have gradually evolved into today's large-scale black and white iron processing plants or companies. Black and white iron processing found that iron products processing is a bright future. Therefore, the company has been committed to the development of iron and steel products, and then these iron products are widely used, and black and white iron is applied in various fields, so this iron is still not enough to achieve a good step. These iron products are industry gatherings, and our country, Although black-and-white iron processing still needs continuous research and development of new products, black-and-white iron, after all, although it is extensive, there is still a long way to go. After all, we need to live. The stability of black-and-white iron is not very good, so the road is still far away. Whether it is black iron or white iron, urban construction plays a crucial role.
