為什么溫室大棚骨架采用熱浸鍍鋅板卷？

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

因?yàn)槭卟朔N植的環(huán)境是一種高溫高濕的環(huán)境，普通的鋼材生銹嚴(yán)重，因此必須使用防腐防銹能力好的骨架材料。同時(shí)設(shè)施農(nóng)業(yè)溫室大棚是一種高投資的產(chǎn)品，因此必須要通過(guò)更長(zhǎng)的使用時(shí)間來(lái)拉低其每年的平均費(fèi)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.

現(xiàn)在越來(lái)越多的農(nóng)戶種植蔬菜用溫室大棚，尤其是在我國(guó)的南方地區(qū)，露天種植現(xiàn)在很難種植出產(chǎn)量品相的蔬菜。蔬菜大棚作用也從反季節(jié)種植到隔絕酸雨、灰塵等作用。我們?cè)诹私鉁厥倚袠I(yè)報(bào)價(jià)的時(shí)候很多的廠家都會(huì)特別提高熱浸鍍鋅骨架材料價(jià)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.

熱鍍鋅管，為了提高鋼管的耐腐蝕性能，對(duì)一般鋼管進(jìn)行鍍鋅。鍍鋅管是使熔融金屬與鐵基體反應(yīng)而產(chǎn)生合金層，從而使基體和鍍層二者相結(jié)合。熱鍍鋅是先將鋼管進(jìn)行酸洗，為了去除鋼管表面的氧化鐵，酸洗后，通過(guò)氯化銨或氯化鋅水溶液或氯化銨和氯化鋅混合水溶液槽中進(jìn)行清洗，然后送入熱浸鍍槽中。熱鍍鋅具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。鋼管基體與熔融的鍍液發(fā)生復(fù)雜的物理、化學(xué)反應(yīng)，形成耐腐蝕的結(jié)構(gòu)緊密的鋅一鐵合金層。合金層與純鋅層、鋼管基體融為一體。故其耐腐蝕能力強(qiáng)。熱鍍鋅骨架材料的優(yōu)點(diǎn)是鋅層厚，防銹能力強(qiáng)，使用壽命在年以上。

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.

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.
