The planting brick manufacturer tells you how much the planting brick size error cannot exceed
The shape specification of the grass planting brick is allowed to have a little deviation. In principle, it has a definite specification and shape, but under the premise of ensuring its service life, it is allowed to have brick surface bending, symmetry, and difference in size and size. error. Errors within this tolerance range are called tolerance errors.
There are two main reasons for determining the allowable errors and misinterpretations of the standard for planting grass bricks:
One is to meet the requirements of the thickness of the brickwork brick joints;
The second is the possibility of planting grass bricks. The thickness of the planting brick brick seam thickness is the thickness of the industrial furnace refractory brick. The significance of the possibility of producing refractory bricks not only includes the possibility of producing such bricks, but also to ensure a suitably high yield. Generally speaking, the tolerance and misinterpretation of grass planting brick specifications should be able to meet the requirements of the thickness of brickwork brick joints. When the specifications of grass planting bricks allow errors and distortions that cannot directly meet the thickness requirements of the brickwork brick joints, you can reduce the errors and distortions by selecting bricks or even grinding them.
According to the requirements of the grade of grass planting bricks, grass planting bricks (standard tolerances and distortions) applicable to Class III brickwork with a thickness of 3 mm or less shall be considered as a second-class product; class II bricks with a thickness of 2 mm or less shall be applicable. The refractory bricks of the bricks are regarded as first-class products; and the grass planting bricks suitable for Class I masonry bricks that do not exceed the thickness of the brick joints are regarded as super-class products. In this way, everyone can take the right seat according to the grass planting bricks produced.
