彩神v济南通风管道变形有四个要害原因是什么?

来源:http://eralgar.com彩神v 日期:2022-04-15 发布人:jntfgd

由于通风管多为厚壁产品,在制造和应用进程中会产生胀大和缩短。这是什么原因?
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?
通风管道变形有四个要害原因:
There are four key reasons for ventilation duct deformation:
1、在自然维护规范下,镁混凝土的体积是一个不断胀大的进程,线胀大率为0.1-0.2%,体积含水率在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、焚烧时磁铁矿难以避免,安装在3C认证防火阀中的粗粒MgO水化进程缓慢。当具有抗压强度的粉煤灰水泥中的MgO再次遇水水化时,转化为Mg(OH)2,体积添加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,轻烧氧化镁中分散的Cao体积添加90%,而卤素片中存在SO42-。当Ca(OH)2转化为老练石膏时,固体体积会添加一倍以上,导致产品变形,这也是约束轻烧镁砂中分散Cao和卤素片中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系统软件的水化进程是一个明显的化学反应进程,制造的管道体积大。假如工作温度高,则反映了加热进程。板自身太高,反射不够,形成晶体地应力和热变形地应力大,产品体积胀大
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
