99% alumina ceramic bulletproof tile , as a high-performance bulletproof material, are gradually becoming an important part of protective equipment in the military, police and some civilian fields. This bulletproof sheet is mainly composed of high-purity alumina (AI203), and its alumina content is as high as 99%, which gives it a series of excellent physical and chemical properties.   First of all, 99% alumina ceramic bulletproof sheets are known for their extremely high hardness and wear resistance. These characteristics enable it to effectively withstand high-energy impacts and reduce the possibility of penetration. At the same time, the compressive strength of alumina ceramics is also very high, which further enhances its bulletproof performance.   In practical applications, this bulletproof sheet can significantly reduce the penetration ability of bullets or other high-speed projectiles on target objects, providing users with reliable protection.   99% alumina ceramic...

Toughened oxide wear - resistant ceramics are a new type of toughened oxide wear-resistant ceramics. Compared with ordinary alumina wear-resistant ceramics, toughened oxide wear-resistant ceramics have achieved a major breakthrough in performance.   Ordinary alumina wear-resistant ceramics are sintered from high-purity alumina powder and have good hardness and wear resistance, but their toughness is poor and they are prone to breakage when impacted, which limits their application in some fields that require high material toughness. Toughened oxide wear-resistant ceramics add zirconium oxide and other substances to alumina. In this way, the toughness of the material is significantly improved, and it also has good thermal shock resistance. In practical applications, toughened oxide wear-resistant ceramics can withstand greater external force impact without breaking, and their service life is greatly extended. The emergence of toughened oxide wear-resistant ceramics is expected to pro...

In the chemical industry, environmental protection and other industrial fields, industrial ceramic ball ring packing is the key to tower equipment, and its selection directly affects production efficiency and cost. Ceramic p all ring packing has a unique structure, with ring, window and tooth structures on the surface, which can increase the gas-liquid contact area, promote fluid turbulence, and improve mass transfer and heat transfer efficiency. Ceramic materials have high hardness, strong pressure resistance, high temperature resistance, acid and alkali resistance, good stability and long service life. When selecting, many factors should be considered. First, the medium characteristics. Ceramic p all ring packing is acid and alkali resistant and very suitable for handling highly corrosive media, such as concentrated sulfuric acid in drying towers and distillation towers in the chemical and metallurgical industries. Second, the type and size of the tower. Different towers have differe...

Before the wear resistance test, the pretreatment of the sample is a key step, which directly affects the accuracy and reliability of the test results. The following are some common steps and requirements for sample treatment before the wear resistance test: I. Sample preparation 1. Sampling: From the wear resistant ceramic material to be tested, use a sampler or suitable tools to cut samples according to the specified size and shape. Usually, the sample should be a standard shape, such as round or square, to facilitate testing and comparison. 2. Surface finish: Ensure that the surface finish of the sample meets the test requirements. If necessary, the sample surface can be treated by grinding, polishing, etc. to remove defects such as scratches and burrs. II. Humidity treatment 1. Constant temperature and humidity environment: Place the sample in a constant temperature and humidity environment to ensure that the sample reaches the state required by the test. Usually, the temperature ...

  The packing is divided into random   tower  packing and structured packing. What should be paid attention to when installing random packing? It is estimated that many people are not very clear.   The stacking of bulk packing is generally not affected by the ellipticity of the tower. In order to facilitate the stacking of random packing into the tower, it is generally placed in a random pile. The recommended error of the conventional random packing tower can be found in the corresponding standard. Generally, after the design is completed according to the standard, the manufacturing and parameters of the packing are also provided by the manufacturer. Sometimes the purchased random packing needs to be processed before use.    There are two methods for loading random packing in the tower: wet loading and dry loading. The so-called wet loading is to fill the tower with water (or process liquid) first, and then load the packing tower packing. This method has a...

Common methods for processing alumina wear   resistant ceramics shared by Chemshun Ceramics factory , welcome to check  Dry grinding: This method uses grinding tools to cut Chemshun alumina ceramics , but attention should be paid to the control of grinding pressure and temperature to avoid surface cracks or breakage. Wet grinding: Coolant is used during the grinding process to reduce the temperature, play a lubricating role, and reduce the impact of grinding force on ceramics. Ultrasonic machining: Cutting using ultrasonic vibration can effectively reduce the impact of grinding force on ceramics, but special ultrasonic machining equipment is required1. Laser machining: Cutting or drilling using laser beams has the advantages of high precision and no pollution, but professional laser machining equipment is required. Cutting: Use high-speed cutting technology to process the blank into the desired shape. Grinding and drilling: Use grinders, wire cutting and other equipment for fi...
