溫室是以采光覆蓋材料作為全部或部分圍護(hù)結(jié)構(gòu)材料，可在冬季或其它不適宜露地植物生長(zhǎng)的季節(jié)供栽培植物的建筑。

Greenhouse is a building with lighting covering materials as all or partial envelope materials, and can be used for cultivated plants in winter or other seasons not suitable for exposed plants.

在北方地區(qū)：主要是起到春提早、秋延后的保溫栽培作用，春季可提早30~50天，秋季能延后20~25天，不能進(jìn)行越冬栽培。

In northern China: it mainly plays the role of heat preservation and cultivation in early spring and autumn extension. When it can be 30 to 50 days early in spring, it can delay 20 to 25 days in autumn, and winter cultivation can not be carried out.

在南方地區(qū)：除了冬春季節(jié)用于蔬菜、花卉的保溫和越冬栽培（葉菜類）外，還可更換成遮陽棚，用于夏秋季節(jié)的遮蔭降溫和防雨、防風(fēng)、防雹等。

In southern China: in addition to the winter and spring for winter insulation of vegetables, flowers (leaf vegetables), can also be replaced with sunshade for shade cooling in summer and autumn, rain prevention, windproof, hail prevention and so on.

所以，材料作為溫室項(xiàng)目工程的源頭，要把好項(xiàng)目質(zhì)量關(guān)，首先要從材料的選用上把好關(guān)。比如溫室項(xiàng)目上用的熱鍍鋅管，在經(jīng)驗(yàn)豐富的鍍鋅廠熱鍍后，質(zhì)檢部門再進(jìn)行檢測(cè)，檢測(cè)合格后才會(huì)運(yùn)往工地使用。

Therefore, materials as the source of greenhouse project projects, to close the quality of the project, first of all, from the selection of materials to the good close.For example, the hot galvanized pipe used in the greenhouse project, in the experienced galvanized plant hot plating, the quality inspection department to test, will be shipped to the construction site after passing the test.

佛山市萬慶物資有限公司現(xiàn)貨批發(fā)的熱鍍鋅板，是將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。主要采用連續(xù)鍍鋅工藝生產(chǎn)，即把成卷的鋼板連續(xù)浸在熔解有鋅的鍍槽中制成鍍鋅鋼板。

Foshan Wanqing Materials Co., Ltd. spot wholesale hot galvanized plate, is a thin steel sheet immersed into the molten zinc tank, so that its surface adhesion to a layer of zinc thin steel plate.Mainly using the continuous galvanization process production, that is, the rolled steel plate is continuously immersed in the molten galvanized plating tank to make a galvanized steel plate.

熱鍍鋅正常防腐不低于30年，冷鍍防腐一二年就上銹了，工藝完全不一樣，相對(duì)來說價(jià)格就有差別了。鍍鋅鋼管大棚分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強(qiáng)，使用壽命長(zhǎng)等優(yōu)點(diǎn)。電鍍鋅成本低，表面不是很光滑，其本身的耐腐蝕性比熱鍍鋅管相差很多。

Hot galvanization normal corrosion is not less than 30 years, cold plating corrosion a year or two on rust, the process is completely different, relatively speaking the price is relatively different.Galvanized steel pipe greenhouse is divided into hot galvanized and galvanized layers, thick, which has the advantages of uniform coating, strong adhesion and long service life.Electrogalvanized cost is low, the surface is not very smooth, and its own corrosion resistance is much different than that of hot galvanized tubes.

熱鍍鋅可分為非合金鍍鋅和合金化鍍鋅：

非合金鍍鋅包括一般用、機(jī)械咬口用、深沖用、超深沖用材質(zhì)。當(dāng)鍍鋅量大時(shí)，耐腐蝕性優(yōu)越，可作暴露件用，鍍鋅量小時(shí)，加工性能良好。

合金化鍍鋅包括沖壓用、結(jié)構(gòu)用、冷成型用材質(zhì)、與純鍍鋅層相比，合金化熱鍍鋅的涂附性和焊接性能更優(yōu)越，但在加工過程中易產(chǎn)生粉化剝離。

Hot galvanization can be divided into non-alloy galvanization and alloyed galvanization:

Non-alloy galvanizing includes general use, mechanical bite, deep flushing, ultra-deep flushing materials.When the galvanizing quantity is large, the corrosion resistance is superior, can be used as exposed parts, galvanized for hours, good processing performance.

Alloy galvanization includes stamping, structure, cold molding material, superior coating adhesion and welding performance of alloy thermal galvanization compared with pure galvanized layer, but it is easy to produce pulverized stripping during the process.

如以前的老房子水管大部分用的就是鍍鋅管，現(xiàn)在煤氣、暖氣用的那種鐵管也是鍍鋅管，鍍鋅管作為水管，使用幾年后，管內(nèi)產(chǎn)生大量銹垢，流出的黃水不僅污染潔具，而且夾雜著不光滑內(nèi)壁滋生的細(xì)菌，銹蝕造成水中重金屬含量過高，嚴(yán)重危害人體的健康。六七十年代，國際上發(fā)達(dá)國家開始開發(fā)新型管材，并陸續(xù)禁用鍍鋅管。中國建設(shè)部等四部委也發(fā)文明確從二000年起禁用鍍鋅管，所以新建小區(qū)的冷水管已經(jīng)很少使用鍍鋅管了。

Such as the old house water pipe mostly is galvanized pipe, now gas, heating with the iron pipe is also galvanized pipe, galvanized pipe as water pipe, after a few years, the pipe produces a large amount of rust scale, out of yellow water not only pollution clean ware, and mixed with not smooth internal wall bacteria, corrosion caused water heavy metal content is too high, serious harm to human health.In the 1960s and 1970s, developed countries in the world began to develop new tubes, and successively banned galvanized tubes.The China Ministry of Construction and other four ministries and commissions have also issued a clear ban on galvanizing pipes from 2000, so cold water pipes in new communities have rarely use galvanizing pipes.
