通風(fēng)管道能夠有用的對室表里空氣進(jìn)行必定的凈化，確?？諝饬魍?，今天就給大家簡單介紹一下玻璃鋼通風(fēng)管道的影響要素，首要是三個方面。

Ventilation pipes can be useful to purify the air in the room surface to ensure air circulation. Today, I will give you a brief introduction of the impact factors of FRP ventilation pipes, the first three aspects.

(1)輕燒氧化鎂

(1) Light burnt magnesia

玻璃鋼通風(fēng)管道的材料之一是輕燒氧化鎂，它是天然菱鎂礦經(jīng)800-900℃煅燒，MgCO3分解成MgO，再經(jīng)磨細(xì)而成。鎂水泥所用的氧化鎂有必要具有活性。氧化鎂的活性是指它與水或MgC12溶液混合后具有發(fā)作水化反響的才能，亦稱水活性。

One of the materials of FRP ventilation duct is light burned magnesia, which is made of natural magnesite calcined at 800 - 900 C, MgCO 3 decomposed into MgO, and then ground. Magnesium oxide used in magnesium cement needs to be active. Magnesium oxide activity refers to its ability to react hydration after mixing with water or MgC12 solution, also known as water activity.

(2)增強玻璃纖維布

(2) Reinforced fiberglass cloth

因為鎂水泥漿體的PH值在8.5-9.5，比硅酸鹽水泥漿體的12.5-13低的多，因而能夠用中堿玻璃纖維網(wǎng)布來做通風(fēng)管道的增強材料。玻纖布的厚度及鋪放層數(shù)對通風(fēng)管道的抗奇強度和抗沖擊強度有很大影響。

Because the PH value of magnesia cement paste is 8.5-9.5, which is much lower than that of Portland cement paste 12.5-13, it is possible to use medium alkali glass fiber mesh to reinforce ventilation ducts. The thickness and layers of fiberglass cloth have great influence on the singular strength and impact strength of ventilation ducts.

通風(fēng)管道中運用高堿布，在短期內(nèi)產(chǎn)品強度也很高，處理好也能達(dá)到標(biāo)準(zhǔn)，但實驗表明，一年后管道的強度下降約40%，以后強度還要逐年下降，而且管道還會開裂、粉化等，因而應(yīng)特別加強對玻璃纖維布的管理和運用。

The use of high alkali cloth in ventilation pipeline can also meet the national standard in a short period of time. But the experiment shows that the strength of pipeline decreases by about 40% after one year, and the strength will decrease year by year. Moreover, the pipeline will crack and pulverize, so the management and application of fiberglass cloth should be strengthened in particular.

(3)工業(yè)氯化鎂

(3) Industrial magnesium chloride

現(xiàn)在市場通的玻璃鋼通風(fēng)管道運用的是工業(yè)氯化鎂，其間一部分海產(chǎn)氯化鎂質(zhì)量較差，首要足NaCl、KCL、CaCl2、SO42-等有育雜質(zhì)合錄過高，從而引起制品吸潮返鹵、泛霜、變形等弊病，因而生產(chǎn)中應(yīng)嚴(yán)格控制其化學(xué)成分。

At present, industrial magnesium chloride is used in FRP ventilation pipelines circulating in the market, and some marine magnesium chloride is of poor quality. The main reason is that the content of fertile impurities such as NaCl, KCL, CaCl2, SO42-is too high, which causes the defects of moisture absorption, brine return, frost and deformation of products. Therefore, the chemical composition of marine magnesium chloride should be strictly controlled in production.
