通风管道能够有用的对室表里空气进行必定的净化，确保空气流通，今天就给大家简单介绍一下玻璃钢通风管道的影响要素，首要是三个方面。

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)轻烧氧化镁

(1) Light burnt magnesia

玻璃钢通风管道的材料之一是轻烧氧化镁，它是天然菱镁矿经800-900℃煅烧，MgCO3分解成MgO，再经磨细而成。镁水泥所用的氧化镁有必要具有活性。氧化镁的活性是指它与水或MgC12溶液混合后具有发作水化反响的才能，亦称水活性。

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)增强玻璃纤维布

(2) Reinforced fiberglass cloth

因为镁水泥浆体的PH值在8.5-9.5，比硅酸盐水泥浆体的12.5-13低的多，因而能够用中碱玻璃纤维网布来做通风管道的增强材料。玻纤布的厚度及铺放层数对通风管道的抗奇强度和抗冲击强度有很大影响。

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.

通风管道中运用高碱布，在短期内产品强度也很高，处理好也能达到标准，但实验表明，一年后管道的强度下降约40%，以后强度还要逐年下降，而且管道还会开裂、粉化等，因而应特别加强对玻璃纤维布的管理和运用。

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)工业氯化镁

(3) Industrial magnesium chloride

现在市场通的玻璃钢通风管道运用的是工业氯化镁，其间一部分海产氯化镁质量较差，首要足NaCl、KCL、CaCl2、SO42-等有育杂质合录过高，从而引起制品吸潮返卤、泛霜、变形等弊病，因而生产中应严格控制其化学成分。

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.
