Special-shaped refractory bricks need to choose a suitable ashing method according to the requirements of use

Special-shaped refractory bricks need to be ashed after the construction is completed. Many users do not understand its function and operation requirements. Therefore, when necessary, we need to use operators to operate. And because of the different ashing methods, we need to operate according to our own Use the requirements to choose.

Take the special-shaped refractory brick in the left hand and the big shovel in the right hand. First make the mortar with a large shovel, and then take the bricks. These operations are the same as brick dust. The tip of the shovel moves back along the edge of the shaped refractory brick, so the mortar naturally forms a raised back for the masonry.

Whether using a tile cutter or a large shovel for ashing, the principle is that the mortar can be opened after it is completely filled and can be observed with a white pigeon. The empty space rate does not exceed 10%. The amount of mud should be based on the size and gray of the brick surface. According to the thickness of the seam, it should not be too much or too little, and the thickness of the ash seam should be ensured for easy operation.

The mud in the ash bucket should be mixed frequently to make the mud evenly mixed and easy to use. Do not stick to the edge of the sludge tank. The mud on the side of the bucket should be scraped into the bucket. When ashing, it should be done as much as possible on the top of the mud bucket. It should be slightly thicker than the conventional joint thickness, and the slurry should be uniformly changed on the surface of the shaped refractory bricks. Don’t let the big shovel touch the brick during ashing, and change it steadily.

The correct ashing of special-shaped refractory bricks is when the masonry is opened after the masonry is completed, it can be seen that the joints are evenly covered by mud. If the ashing is not good, there will be empty space on the contact surface, thereby reducing the brick body Adhesion may cause leakage of the masonry and seriously affect the quality of the overall wall. Therefore, we need to choose a suitable ash ashing method according to our own needs.
