The Types Of Cracks Of Magnesia Brick

No matter what kind of magnesia brick, different degrees of crack will be produced in the drying process. There are two types of cracks of magnesia brick, one is mechanical crack, and another is non mechanical crack.

Under normal circumstances, the direction and location characteristics of mechanical crack are obvious, intuitive, crack longer and clearly visible. Mechanical cracking is because the body is subject to the impact of a collision, vibration caused by pressing. Mechanical crack is caused by the impact of the body and the vibration caused by the press.

Non mechanical crack, the form of its expression is varied, generally speaking, the direction is not so obvious. But quite a lot of time, non mechanical crack, the location of the crack is also more regular; therefore, it can not be simply considered that as long as the obvious direction is mechanical cracking. In many times, mechanical crack and non mechanical crack are easily confused and easy to make people wrongly judgment and cause significant losses, so this must be paid the special attention to the problem.
