In the process of our home renovation, we often use many kinds of professional building materials. Some owners are prone to buying and selling when buying these materials. For example, we often use porcelain tiles . Many people do not understand the characteristics of porcelain tiles . So what are the characteristics of porcelain tiles, porcelain tiles and ceramic tiles are different from it, the following porcelain brick bureau for everyone to introduce it. Porcelain tile What are the characteristics a: ceramic tile categories Porcelain tiles can be divided into glazed porcelain tiles, unglazed porcelain tiles, polished porcelain tiles, non-polished porcelain tiles, and non-slip porcelain tiles according to its appearance and applications. Polished tiles are usually fired at one time. , Its cost is relatively low, the color is low, but the surface is smooth, the blank body vitrification effect is outstanding. Some ceramic bricks also use secondary firing technology. Such porcelain bricks usually have good water absorption, smooth glazes, and excellent green body strength. They do not require too much manual operation. At the same time, after the second high-temperature combustion, the internal basic No problems with pinholes, air bubbles, etc. will occur. Porcelain tile What are the characteristics II: ceramic tile features introduced 1. Porcelain tiles are mainly classified into two types: polished and non-polished. The appearance of the polished tiles looks beautiful and noble, while the non-polished tiles look flat, but they are widely used in our house decoration. 2. The color and texture of ceramic tile surface and interior are the same. The product adopts complete porcelain, tight structure, relatively hard, no distorting and discoloration. The hardness can reach Mohs' 6 or above, with excellent wear resistance and no fading. performance. Porcelain tiles have a water absorption rate of less than 0.5%. They have excellent frost resistance, cold and heat resistance, and are not susceptible to cracking. They can adapt to various climatic conditions. 3, porcelain tile performance is stable, easy to break, corrosion resistance, light weight, simple processing and low price, is the choice of many people in home improvement materials. What is the difference between porcelain tiles and ceramic tiles? 1. The biggest difference between porcelain tile and ceramic tile is that with the water absorption rate, the water absorption rate of porcelain tile is usually lower than 0.5%, while that of ceramic tile is usually above 10%. The water absorption performance of ceramic tile is far more than that of porcelain. Bricks. 2. The structure of ceramic bricks is rough, the air is more, the sound is boring when striking, and the porcelain brick has a compact structure, excellent surface gloss performance, the sound is crisper when striking, and the abrasion resistance of porcelain tiles Stronger than pottery bricks. 3. Most of the sanitary wares in our lives are basically made of porcelain bricks, while the wall bricks are basically made of ceramic bricks. This is based on their different characteristics. Article Summary: The above is about the porcelain tiles have related presentations What is the difference of what characteristics and porcelain tiles and ceramic tiles, hope that they can provide some help in the house decoration of the time, let us know any more material housing renovation should be used Okay, let's not buy it when you buy materials.
Piston Seals and Rod Seals are important seals used in mechanical equipment. Their main function is to prevent liquid and gas leaks and ensure the normal operation of mechanical equipment. Piston seals and rod seals are usually used in hydraulic and Pressure system, such as hydraulic cylinders and Pneumatic cylinder. The quality and performance of these seals directly affect the efficiency and lifespan of mechanical equipment.
The classification of piston seals and rod seals is mainly based on their material and design structure. According to the different materials, they can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, metal seals, etc. According to the different design structures, they can be divided into unidirectional seals, bidirectional seals, rotary seals, etc.
Rubber seals are a common type of seal, and their main material is rubber. Rubber seals have good sealing performance and wear resistance, and are suitable for medium and low pressure hydraulic systems and Pressure system. Polyurethane sealing element is a high-performance sealing element, and its main material is polyurethane. Polyurethane seals have high wear resistance, high temperature performance and high pressure performance, and are suitable for high-pressure hydraulic systems and Pressure system. PTFE sealing element is a corrosion-resistant sealing element, and its main material is PTFE. PTFE seals have excellent corrosion resistance and high temperature resistance, making them suitable for fields such as chemical and food processing. Metal seals are a type of high-temperature and high-pressure seal, mainly made of metal. Metal seals have high temperature and high pressure performance and corrosion resistance, and are suitable for high temperature and high pressure hydraulic systems and Pressure system.
Unidirectional seals and bidirectional seals are classified based on different sealing directions. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. Rotating seal is a type of seal that can rotate and is mainly used for sealing rotating shafts. Rotary seals are divided into unidirectional rotary seals and bidirectional rotary seals.
