Aluminum pigments to buy appearance factors 1. Brightness/Whiteness The coarser the pigment particles, the rounder the shape, the higher the proportion of reflected light, and therefore the brighter and the more white 2 . Glittering refers to the change in whiteness when viewed at different angles. The thicker the pigment particles are, the more round the shape is, and the stronger the glittering effect of different colors is. 3. The finer the hiding power and distinct image pigment particles, the more irregular the particle structure, the higher the proportion of scattered light, the more homogeneous the appearance, and the higher the hiding power, the better the DOI. The higher the distinctness of the image, the more mirror effect the clearer the image of the coating surface will be.
Aluminum pigments to buy the main technical parameters 1. The coarser the particle size of the aluminum particle of the particle size, the brighter the whiteness and the flashiness, and the finer the particle size of the aluminum pigment, the better the hiding power and the distinctness of the image.
2. The particle size distribution of aluminum pigments is not only related to the pigment particle size but also to the particle size distribution system. The narrower the particle size distribution indicates that the more uniform the particle size in the product, the better the optical characteristics.
3. The metal used for surface treatment and particle shape production is ductile, so grinding in a ball mill to grind the atomized ball ** can form flaky particles with a form factor (thickness-to-height ratio) up to 1:50 ~1:500. The particle shape can be irregular (flake type), or completely round (silver circle type).
Silver round pigments are the latest generation of products with excellent optical properties. They use special, very fine materials, and they are manufactured through extremely fine processing techniques.
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.
