为什么温室大棚骨架采用热浸镀锌板卷？

Why does the greenhouse frame use a hot-dip galvanized sheet roll?

因为蔬菜种植的环境是一种高温高湿的环境，普通的钢材生锈严重，因此必须使用防腐防锈能力好的骨架材料。同时设施农业温室大棚是一种高投资的产品，因此必须要通过更长的使用时间来拉低其每年的平均费用。

Because the vegetable planting environment is a high temperature and high humidity environment, ordinary steel rust is serious, so we must use good corrosion and corrosion resistance skeleton materials.At the same time, facility agriculture greenhouses are a high investment product, so they must lower the average annual cost through a longer use time.

现在越来越多的农户种植蔬菜用温室大棚，尤其是在我国的南方地区，露天种植现在很难种植出产量品相的蔬菜。蔬菜大棚作用也从反季节种植到隔绝酸雨、灰尘等作用。我们在了解温室行业报价的时候很多的厂家都会特别提高热浸镀锌骨架材料价格。

Nowadays, more and more farmers use greenhouses to grow vegetables, especially in southern China, where it is now difficult to grow vegetables with production and appearance.Vegetable greenhouse effect is also from out-of-season planting to the isolation of acid rain, dust and other effects.When we understand the greenhouse industry quotation, many manufacturers will especially improve the price of hot-dip galvanized skeleton materials.

热镀锌管，为了提高钢管的耐腐蚀性能，对一般钢管进行镀锌。镀锌管是使熔融金属与铁基体反应而产生合金层，从而使基体和镀层二者相结合。热镀锌是先将钢管进行酸洗，为了去除钢管表面的氧化铁，酸洗后，通过氯化铵或氯化锌水溶液或氯化铵和氯化锌混合水溶液槽中进行清洗，然后送入热浸镀槽中。热镀锌具有镀层均匀，附着力强，使用寿命长等优点。钢管基体与熔融的镀液发生复杂的物理、化学反应，形成耐腐蚀的结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体。故其耐腐蚀能力强。热镀锌骨架材料的优点是锌层厚，防锈能力强，使用寿命在年以上。

Hot galvanized pipe to improve the corrosion resistance of steel pipes.The galvanized pipe produces an alloy layer reactive between the molten metal and the iron matrix, thus combining both the substrate and the plating layer.Hot galvanizing is the first steel pipe, to remove iron oxide on the surface of the steel pipe, after washing, through ammonium chloride or zinc chloride solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot dip tank.Hot-plated galvanizing has the advantages of uniform coating, strong adhesion and long service life.The steel pipe matrix and the molten plating liquid undergo complex physical and chemical reactions, forming a corrosion-resistant structure of a tight zinc monoferroalloy layer.Alloy layer is integrated with pure zinc layer and steel pipe substrate.Therefore, its corrosion resistance ability is strong.The advantages of hot galvanized skeleton materials are thick zinc layer, strong rust prevention ability, and service life of more than years.

来到二月尾，乐从冷轧早盘报价相对稳定，在报价的基础上给予10-20元/吨优惠空间。总体来看，乐从冷轧价格继续盘整运行；乐从镀锌板卷价格主流暂稳运行，成交方面，据部分商家反馈，乐从市场镀锌板卷成交量较上月略有好转，预计乐从镀锌板卷价格或将稳中偏强运行为主。

At the end of February, Lecong cold rolling morning quotation is relatively stable, on the basis of the quotation to give 10-20 yuan / ton of preferential space.In general, Lecong cold rolling price continues to consolidate operation; Lecong galvanized roll price mainstream temporarily stable operation, transaction, according to the feedback of some businesses, Lecong market galvanized roll volume slightly better than last month, it is expected that Lecong galvanized roll price or will be stable and strong operation.
