As the ventilation pipes are mostly thick wall products, they will swell and shorten in the process of manufacturing and application. What's the reason?

通風管道變形有四個要害原因：

There are four key reasons for ventilation duct deformation:

1、在自然維護規范下，鎂混凝土的體積是一個不斷脹大的進程，線脹大率為0.1-0.2%，體積含水率在1%左右。

1. Under the natural maintenance specification, the volume of magnesium concrete is a continuous expansion process, with the linear expansion rate of 0.1-0.2% and the volume moisture content of about 1%.

2、焚燒時磁鐵礦難以避免，安裝在3C認證防火閥中的粗粒MgO水化進程緩慢。當具有抗壓強度的粉煤灰水泥中的MgO再次遇水水化時，轉化為Mg(OH)2，體積添加120%。

2. Magnetite is difficult to avoid during incineration, and the hydration process of coarse MgO installed in 3C certified fire damper is slow. When MgO in fly ash cement with compressive strength is hydrated again, it is converted to Mg (OH) 2 and added by 120% by volume.

3、水化后，輕燒氧化鎂中分散的Cao體積添加90%，而鹵素片中存在SO42-。當Ca(OH)2轉化為老練石膏時，固體體積會添加一倍以上，導致產品變形，這也是約束輕燒鎂砂中分散Cao和鹵素片中SO42-含量的原因。

3. After hydration, the volume of dispersed Cao in lightly burned magnesia was added by 90%, while SO42 - was present in halogen tablets. When Ca (OH) 2 is converted into aged gypsum, the solid volume will be more than doubled, resulting in product deformation, which is also the reason for restricting the content of dispersed Cao in light burned magnesia and SO42 - in halogen tablets.

4、mgo-mg-c12-h2o系統軟件的水化進程是一個明顯的化學反應進程，制造的管道體積大。假如工作溫度高，則反映了加熱進程。板自身太高，反射不夠，形成晶體地應力和熱變形地應力大，產品體積脹大

4. The hydration process of mgo-mg-c12-h2o system software is an obvious chemical reaction process, and the volume of the manufactured pipeline is large. If the working temperature is high, it reflects the heating process. The plate itself is too high, the reflection is not enough, the formation of crystal in-situ stress and thermal deformation in-situ stress is large, and the volume of the product is expanded
