导致通风管道变形的原因有哪些？
山东通风管道在我们的生活中担任着非常重要的作用，由于通风管道大多是一些薄壁产品，所以在生产和使用的过程中，会出现翘曲变形的现象。那么导致通风管道变形的原因有哪些呢?山东通风管道厂家为大家介绍一下：
Shandong ventilation pipeline plays a very important role in our life. Because most of the ventilation pipelines are thin-walled products, warping and deformation will occur in the process of production and use. So what are the reasons for the deformation of ventilation ducts? Shandong ventilation duct manufacturers will introduce to you:
1、镁水泥在自然养护条件下其体积是一个连续膨胀过程，其线膨胀率为0.1-0.2%，体积膨胀率约为1%。
1. The volume of magnesia cement is a continuous expansion process under natural curing conditions. Its linear expansion rate is 0.1-0.2%, and its volume expansion rate is about 1%.
2、菱镁矿在服烧过程中不可避免地产生局部过烧，使一部分MgO呈死烧状态，过烧的MgO水化过程很慢，当已形成强度的水泥石中的MgO再遇水进行水化时，生成Mg(OH)2，体积膨胀120%。
2. Magnesite inevitably produces local overburning in the course of serving and burning, which makes part of MgO in a dead state. The hydration process of overburned MgO is very slow. When MgO in the cement stone with formed strength is hydrated by water again, Mg(OH)2 is formed and its volume expands by 120%.
3、轻烧氧化镁中游离CaO水化时体积膨胀90%，而卤片中存在着 SO42-，当Ca(OH)2转化成石膏时，固体体积将增加2倍以上，导致制品变形，这也是限制轻烧氧化镁中游离CaO含量、卤片中SO42-含量的原因。

3. Volume expansion of free CaO in light-burned magnesia is 90% when hydration occurs, while SO42-exists in brine tablets. When Ca(OH)2 is converted into gypsum, solid volume will increase by more than two times, resulting in product deformation, which is also the reason for limiting free CaO content in light-burned magnesia and SO42-content in brine tablets.
4、MgO-Mg-C12-H2O系统水化过程是一个强烈的放热反应过程，而生产的管道体积又大，若环境温度较高，则反应升温过程，板材本体温度过高，反应不充分，造成较大的结晶应力和热膨胀应力，使制品体积膨胀。
4. The hydration process of MgO-Mg-C12-H2O system is a strong exothermic reaction process, and the volume of the pipeline is large. If the ambient temperature is high, the reaction heating process will occur. The temperature of the sheet body is too high and the reaction is not enough, resulting in larger crystallization stress and thermal expansion stress, which will cause the volume expansion of the product.
以上就是通风管道变形的4方面原因，了解这些变形原因可以帮助我们更好的问题，只要及时，是不会影响正常的工作的。但是不管在什么时候，我们都要严格按照操作规范，这样才能够保证通风管道有效发挥出使用效果。以上就是山东通风管道厂家为大家介绍的全部内容，希望对大家有所帮助!
These are the four reasons for the deformation of ventilation pipes. Understanding these causes can help us solve the problem better. As long as the problem is solved in time, it will not affect the normal work. However, no matter when, we must strictly follow the operation specifications, so as to ensure the effective use of ventilation pipes.
