怎么正确挑选耐植草砖 How to choose grass- tolerant bricks
Chemical companies need to buy grass-resistant bricks when they set up factories or renovate their decoration. So how can you choose inexpensive, durable, and beautiful acid-resistant bricks? There is also a certain degree of knowledge in choosing acid-resistant bricks. In general, the principles for buying ceramic tiles are: one look, two listens, three drops of water, four feet of volume, and five tests.
First, look first. The color of the grass-tolerant brick must be uniform, the surface smoothness and flatness must be good, there must be no unevenness, the four surrounding lines must be regular, the edges and corners must not have defects, and there must be no edges and corners. They can be picked up and aligned like a carpenter Seeing with the naked eye, otherwise it will affect the construction, even if it can be used for decoration, it will affect the life of the tile because the gap between the tiles is too large.
Second, listen. Flick with your fingers, the sound is more crisp and pleasant, it shows that the degree of porcelain is very high, and the quality is good. If the sound is dull, as in martial arts novels, such as defeating leather and dirty sound, the quality of such tiles is not good.
Third, then drip. Turn the plant-resistant grass tile upside down, put a drop of water in the middle, and watch the water to see the speed of water penetration on the back of the tile. The faster the speed, the lower the density of the tile, the lower the quality, and the slower the water absorption, the lower the density of the tile. Larger, good quality, if you do n’t know how many moments, you can refer to the larger brand, the quality is indeed better, and test it together to determine the soaking moment.
Fourth, the ruler is again. The regularity of the grass-tolerant bricks can be investigated with the naked eye, but the accuracy and flatness of the variable length require the instrument. The accuracy of the side length can be measured with a ruler, and the angle must be measured with a right-angle caliper. Whether the entire plant-resistant grass brick is in the same plane, you can choose to test it on the glass, or the two tiles can be changed back and tiled together to see if there is a vacant space in the middle of the two tiles. , Good flatness, the same margin) is better, it will be with construction, and durable.
Fifth, tests, including physical and chemical tests, the physical test is to see the hardness of the grass-resistant bricks with scratches each other, without showing scratches
The quality is good. If there are scratches, the general chemical test is to use a corrosive chemical product such as sulfuric acid and fire alkali to test the surface's corrosion resistance. Generally, bidding for procurement can allow manufacturers to send samples for long-term testing. The best Abrasion tests in corrosive environments have a faster effect on the test.
