生产工艺上浅谈镀锌脚手架的区别

乌鲁木齐脚手架价格盘整观望厂家接货较为谨…脚手架乌鲁木齐脚手架市场各脚手架厂家平稳报价,市场成交较差且量不稳定。据了解,目前市场大户日均成交百吨左右,中小户则只有30-50吨成交量。另据脚手架厂家反馈,随着季节性淡季的来临,乌鲁木齐脚手架市场销售逐渐转淡,多数终端大户接单情况较差,因而脚手架采购量较之前缩量明显。且近期受八钢和酒钢资源到 …

简单聊聊镀锌脚手架的集中分类,我们先从其出产工艺上来看,这样是可以分为热镀锌脚手架和冷镀锌脚手架的。正是由于这两种镀锌脚手架的加不相同也就造就了它们许多不同的物理和化学性质。总的来说它们在强度、耐性和机械功能方面都有许多的差异。热镀锌脚手架:是在运用钢板或者是钢带弯曲成型后焊接制成的脚手架,并在这种脚手架的根底大将脚手架置于热镀锌池中经过一系列化学反应后又形成的一种脚手架。热镀锌脚手架的出产工艺较为简略,且出产功率是很高的,种类标准也多,这种脚手架所需求的设备和资金很少,适合小型镀锌脚手架厂家的出产。可是从强度上来说这种钢管的强度是远远低于无缝脚手架的。
In brief, the centralized classification of galvanized square tubes can be divided into hot galvanized square tubes and cold galvanized square tubes. It is precisely because of the different addition of these two galvanized square tubes that many different physical and chemical properties of them are created. Generally speaking, they differ in strength, endurance and mechanical function. Hot-dip galvanized square pipe: a square pipe which is welded by bending of steel plate or strip and placed in a hot-dip galvanizing bath at the root of the square pipe after a series of chemical reactions. The production process of hot-dip galvanized square tubes is relatively simple, and the output power is very high, and there are many kinds of standards. The square tubes require little equipment and capital, which is suitable for the production of small-scale galvanized square tubes manufacturers. But in terms of strength, the strength of this kind of steel pipe is far lower than that of seamless square pipe. ??而冷镀锌脚手架是在所用的脚手架上使用冷镀锌的原理来使脚手架具有防腐蚀的功能。与热镀锌不同冷镀锌涂料首要经过电化学原理来进行防腐,因而必须保证锌粉与钢材的充分触摸,发生电极电位差,所以钢材外表处理很重要。
And the cold galvanized square pipe is to use the principle of cold galvanizing on the square pipe used to make the square pipe have the function of anti-corrosion. Different from hot-dip galvanizing, cold-dip galvanizing coatings are mainly anticorrosive by electrochemical principle. Therefore, it is necessary to ensure the full touch between zinc powder and steel, and the potential difference between electrodes occurs. Therefore, the surface treatment of steel is very important.

镀锌脚手架有热镀锌脚手架和电镀锌脚手架两大类。热镀锌脚手架有湿法、干法、铅锌法、氧化还原法等。不同热镀锌办法的首要差异在钢管酸浸清洗后,用什么办法活化管体外表进步镀锌质量。现出产中首要选用干法和氧化还原法,其特点见表。电镀锌的锌层外表非常光滑细密、组织均匀;具有杰出的力学功能和抗腐蚀能力;锌耗比热镀锌低60%~75%。电镀锌在技术上有一定的复杂性,但对单面镀层,内外外表镀层厚度不同的双面镀层,以及薄壁管镀锌等皆须选用此法。
_galvanized square tubes can be divided into hot galvanized square tubes and galvanized square tubes. Hot-dip galvanized square pipe has wet method, dry method, lead-zinc method, oxidation-reduction method and so on. The primary difference between different hot-dip galvanizing methods is how to activate the outside surface of the pipe to improve galvanizing quality after acid leaching cleaning. Dry method and redox method are the most important methods in production. Their characteristics are shown in the table. The zinc coating of galvanizing is very smooth, compact and uniform in structure. It has excellent mechanical function and corrosion resistance. The consumption of zinc is 60%-75% lower than that of hot galvanizing. Electroplating zinc is technically complicated, but it is necessary to select this method for single-side coating, double-sided coating with different thickness of inner and outer coating, and thin-walled tube galvanizing.
