Speaking of the word ceramic tile, we all know that it is a commonly used building material, but! ! ! Speaking of what acid-resistant ceramic tiles are, you don’t know! Today Zhongtaojun is here again to share useful information. Let’s talk about what acid-resistant ceramic tile is and what its characteristics are!
Acid-resistant bricks are not used for home decoration. The main component of acid-resistant ceramics is silica, which forms mullite when roasted at high temperatures. Acid is a high-performance material. Due to the acid-resistant brick structure and low water absorption, it is resistant to alkaline media of any concentration at room temperature, but not Resistant to high temperature molten alkali. Acid-resistant bricks containing more than 70% silica formed by sintering in the chemical industry are mainly used for masonry, wells, ditch acid acid and alkali storage and large-area acid impact.
1. Characteristics of acid-resistant ceramic tiles
The main component of acid-resistant ceramics is silica, which forms mullite when roasted at high temperatures. Acid is a high-performance material. Due to its acid-resistant brick structure and low water absorption, it is resistant to alkaline media of any concentration at room temperature. , but not resistant to high temperature molten alkali. Acid-resistant bricks containing more than 70% silica formed by sintering in the chemical industry are mainly used for masonry, wells, ditch acid acid and alkali storage and large-area acid impact.
Due to the acidic brick-board structure and low water absorption, it can resist alkaline media at any concentration at room temperature, but it is not resistant to high-temperature molten alkali. Acid bricks contain more than 70% silica and are sintered and molded in the chemical industry. They are mainly used for masonry, wells, acid and alkali storage and acid impact on the ground.
2. Product application of acid-resistant ceramic tiles
Acid-resistant bricks are widely used in petroleum, chemical, pharmaceutical, food, papermaking, fertilizer, pesticide, chemical fiber, textile, metallurgy, power plants and other industries, as well as anti-corrosion linings of towers, pools, tanks, tanks, and sewage treatment projects and open areas The work site exerts its acidic preservative effects. Acid-resistant bricks can resist most media except hydrofluoric acid, phosphorus and concentrated alkali. They have good anti-corrosion effects on wet chlorine, salt water, hydrochloric acid, sulfuric acid, nitric acid and alkali at room temperature.
3. Selection tips for acid-resistant ceramic tiles
Whenever you see any item, first of all, you must use your eyes to carefully observe the selection. For example, when choosing acid-resistant ceramic tiles, you must see whether its color is uniform. The color of good ceramic tiles must be uniform, and the surface finish and smoothness must beThe edges are of good degree and not convex. The acid-resistant ceramic tiles should be neat in these places and corners. Try not to have defects, which will affect the construction and construction, and the service life will be greatly reduced.
Flick with your fingers, listen to the sound, and choose acid-resistant ceramic tiles. You can play with your fingers. If the sound is more pleasant, it means that the quality of the acid-resistant ceramic tiles is good. If the sound is dull, it is best not to choose it.
This method of drop test is to test the density of ceramic tiles. Drop a drop of water on the back of the middle ceramic tile to see the penetration rate and speed of water on the back. It shows that the density is low and the quality is not good. Otherwise, the quality is not good.
The uniformity of acid-resistant ceramic tiles can be observed with the naked eye, but for longer accuracy and smoothness, you need the help of instruments. The length can be measured with accuracy through a right-angle measuring caliper. Where it is flat, that is where the entire acid-resistant ceramic tile is. On the same plane, you can choose the glass test, or two tiles are tiled together with callbacks to acid. Whether there is a gap between the two tiles in the middle, it is better than (high right angle accuracy, good flatness, and the same edge) , and construction, durability.
The test of acid-resistant ceramics includes physical tests and chemical tests. The physical test is acid-resistant ceramic water chestnut hardness scratches, no scratches, good quality. If there are scratches, the chemical test quality is generally corrosive chemicals such as sulfuric acid and hydrogen. Sodium oxide is used for surface corrosion resistance testing. Generally, the bidding allows manufacturers to send samples for a long period of time. It is best to perform wear tests in corrosive environments. The test results are fast.
The above is what I said today about the characteristics of Acid-resistant ceramic tiles and some of its product application and selection skills. Well, that’s it for today’s sharing!
