The service life of refractory bricks in high temperature furnaces is closely related to many factors or external factors. For example, in the face of many customers, friends will ask, will refractory bricks absorb water? Can wet water still be used later? I am clearly answering this question to you here. The refractory brick itself has pores, so the refractory brick is absorbent, and the amount of water absorption is determined by its porosity. Divided into three categories: one side is closed, the other side is connected to the outside world, called open pores; closed samples are not connected to the outside world, called closed pores, in traditional multi-sided samples are called open pores. stomata. The internal structure of refractory bricks is destined to be a good or bad material from raw materials to pressing to firing. National and non-national standards. China has different content standards for different types of refractory bricks. In the process of using refractory bricks, we often encounter some uncertain factors. For example, during the construction process, the refractory bricks encountered rainy weather.
In this case, strictly speaking, it is very wrong if it is not stored correctly from the storage source, so it cannot be used, but in the actual production process, the national standard is the acceptance standard. Most purchasing companies will still buy refractory bricks according to their required standards, and the intrinsic quality of refractory bricks will be judged by their physical and chemical indicators.
