Teach you how to judge the quality of the floor tiles

Take a piece from the packing box to see if the surface is flat and intact. The glazed surface should be even and bright, without spots, glaze, bumps, and the surrounding edges are regular. The glazed surface is not bright, bun or bubbles are quality problems.

(2) Take out another piece of floor tile, and the two pieces are aligned. The smaller the gap is, the better. If it is a pattern brick, you must use four pieces to piece together a complete pattern. You should also be optimistic about whether the pattern of the brick is connected and clear. Then take out a box of bricks and lie flat on a large plane. See the whole effect from a distance. Regardless of white, other colors or patterns, the color should be the same. If there are individual bricks, either deep or shallow, it will be difficult to see. Affect the entire decorative effect.

(3) Put these bricks together and erect one piece to compare the size of the bricks. The small brick deviation is allowed to be plus or minus 1 mm, and the large brick is allowed to be plus or minus 2 mm.

(4) Take a piece of brick to knock another piece, or use another hard object to knock the brick. If the sound of the brick is crisp and loud, it means the brick is of good quality and cooked. If the sound is abnormal, it means there is heavy skin in the brick or Crack phenomenon: When the brick is formed, the air in the material is not discharged, resulting in poor bonding between the material and the material, and internal cracking. It is not visible from the surface, and can only be identified by listening to the sound.

Tungsten carbide endmill is mainly used for CNC machining centers, cnc engraving machine. It can also be installed on the ordinary milling machine to deal with some of the harder and less complex heat treatment materials. Cemented Carbide is a hard material used extensively in cutting tools for machining, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites. Most of the time, carbide cutters will leave a better surface finish on the part, and allow faster machining than high-speed steel or other tool steels. Carbide tools can withstand higher temperatures at the cutter-workpiece interface than standard high-speed steel tools (which is a principal reason for the faster machining). Carbide is usually superior for the cutting of tough materials such as carbon steel or stainless steel, as well as in situations where other cutting tools would wear away faster, such as high-quantity production runs.
