Tiles to buy a look at two listening three trials

In the home decoration, the ceramic tile is one of the materials that must be indispensable. It should be noted that it is not a kind of ceramic tile that can be used for the whole decoration. Generally, various ceramic tiles are selected according to different regions and functions, so pay attention to the purchase of ceramic tiles. Second, listen to three trials.

When buying ceramic tiles, pay attention to four steps: look at the surface, see if the color of the tile surface is uniform, the smoothness of the surface and the flatness. To ensure the complete pattern of the tile, you can randomly pick out a few pieces from a box of bricks to check it. See if there is any color difference, deformation and damage, and pay attention to whether there are cracks, bubbles and other defects on the tile surface. The second is to listen to the sound. When purchasing tiles, you should judge the pros and cons of the tiles through the sound. You can use the hard object to tap. The more the sound is crisper, the higher the quality, the better the quality. You can also use the left thumb, forefinger and middle finger to clip the corner of the tile and hang it down easily. Use your right index finger to tap the middle and lower part of the tile. If the sound is crisp and bright, it will be excellent, such as the sound is dull and turbid. The third is to test the water absorption. When purchasing the tile, pay attention to test the water absorption problem. The water droplets will be on the back of the tile to see the speed of the infiltration. The slower the water absorption, the higher the density and the better the relative quality. If the water absorption speed is very fast, then , indicating that the density of the tiles is relatively sparse and the quality is relatively poor. The fourth is the size. The higher the accuracy of the length of the tile, the better the effect after the paving. Buying high-quality tiles is not only easy to construct, but also saves working hours and accessories. Use a tape measure or a caliper to measure the difference in the size of each tile. The accuracy is high.

When buying ceramic tiles, pay attention to the test: First, the eye touch, the anti-slip property of the tile is very important. When buying the tile, you must pay attention to the method of using the eye touch to judge the anti-slip effect of the tile. If it seems that the surface of the brick is as smooth and smooth as a mirror, then the anti-slip property is generally poor. You can touch the surface of the tile by hand and feel it. If you feel it, the anti-slip effect of the tile is better. The second is the foot test. When purchasing the floor tiles, discuss with the store first. You can walk directly on the brick surface to test the anti-slip effect. If you walk to feel the slippery, then do not choose this brick in the kitchen and balcony. The third is to test the water. When you buy the tiles, you must do a test of the water test. You can lay two large tiles on the floor. If the tile surface is waxed or oiled, you need to remove it in advance, and then test it. The water sprinkles on the surface of the tile, then walks back and forth with the shoes to see if there is any feeling of slipping, and if so, the slip resistance of the tile is poor.

Dosing Pump

Dosing Pump Characteristic :

1 Clean and pollution-free: fluid only passes through and touches the Peristaltic Pump hose.

2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
