3A molecular sieve,sometimes also known as 3A zeolitemolecular sieve,is a kind of potassium-sodium aluminosilicate with LTA-type skeleton structure which is composed of silicon-oxygen and aluminum-oxygen tetrahedrons.The main crystal hole of the 3A molecular sieve is an eight-membered ring structure, and the crystal pore size is 3Å (0.3nm).This kind of Molecular Sieve is mainly used to adsorb water, and does not adsorb any molecule with a diameter larger than 3A. According to the characteristics of industrial applications, the molecular sieve 3A produced by Fulong has faster adsorption speed, more regeneration times, higher crushing strength and stronger wear resistance,which greatly improves the utilization efficiency of molecular sieves and prolongs the service life of molecular sieves.It is the first choice desiccant necessary for deep drying,refining and polymerization of gas and liquid phases in petroleum and chemical industries. 4A molecular sieve is a kind of potassium-sodium aluminosilicate with LTA-type skeleton structure which is composed of silicon-oxygen and aluminum-oxygen tetrahedrons.The main crystal hole of the 4A molecular sieve is an eight- membered ring structure, and the crystal pore size is 4Å (0.4nm).It can adsorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene, but does not adsorb any molecule with diameter greater than 4A (including propane). Its selective adsorption performance for water is higher than that of any other molecule.It is one of the largest molecular sieves varieties in industry.It is widely used in the drying of gases and liquids, and also in the refining and purification of some gases or liquids, such as the preparation of argon. 5A molecular sieve, generally also known as calcium molecular sieve with an effective pore opening of 5 angstroms, can absorb any molecule smaller than this pore size. In addition to the functions of 3A and 4A molecular sieves, it can also adsorb C3-C4 normal alkanes, chloroethane, bromoethane, butanol, etc., and can also be used for the separation of normal isomers, pressure swing adsorption separation and the co-adsorption of water and carbon dioxide. 13X molecular sieve, also known as sodium X molecular sieve, is an alkali metal aluminosilicate with a certain alkalinity. With the pore size of 10A,13X molecular sieve can adsorb any molecules larger than 3.64A and smaller than 10A.It can be used for catalyst co-carrier, water and carbon dioxide co- adsorption, water and hydrogen sulfide gas co-adsorption. It is mainly used in the drying of medicine and air compression system, and has different specialty varieties according to different applications.With the highest theoretical capacity of the common adsorbents and very good mass transfer rates, 13X molecular sieve is also often used as high-capacity adsorbents which is widely used in cryopumping, drying of cracked gas, air separation, natural gas Processing, Petrochemical industry and catalysis of hydrocarbon Processing and air separation.

　　In the realm of oil seals, the term "TC" is often used to describe a specific type known as skeleton oil seals. In this article, we will explore the meaning of TC in skeleton oil seals, shedding light on its significance and implications. Additionally, I will provide personal insights to enhance the understanding of this terminology. 　　Understanding Skeleton Oil Seals: 　　Skeleton oil seals, also referred to as TC oil seals, are widely used in various industries to prevent fluid leakage and contamination. They are designed with a metal or plastic skeleton frame embedded within a rubber or elastomeric casing. The skeleton provides structural support, while the flexible sealing lip made of rubber ensures efficient sealing around the rotating or reciprocating shaft. 　　Decoding the TC Abbreviation: 　　The "TC" abbreviation in skeleton oil seals holds specific meanings that provide information about the seal's design and functionality. It typically represents two distinct components: 　　"T" Designation: The "T" in TC stands for "double-lip" or "double-lipped." This indicates that the seal has two sealing lips, one on each side of the skeleton frame. The double-lip design enhances the sealing effectiveness by providing an additional layer of protection against fluid leakage. 　　"C" Designation: The "C" in TC signifies the type of sealing lip used in the oil seal. In the case of TC oil seals, the "C" represents a rubber or elastomeric lip. This flexible lip comes into contact with the rotating or reciprocating shaft, forming a dynamic seal to prevent fluid leakage. 　　I recognize the significance of the TC designation in skeleton oil seals. The double-lip design offers advantages such as improved sealing performance, increased resistance to contaminants, and enhanced durability. The rubber or elastomeric lip is highly effective in maintaining a consistent sealing interface with the shaft, ensuring efficient fluid containment and lubrication retention. 　　Furthermore, it is worth noting that TC oil seals are widely utilized in demanding applications where reliability and efficiency are paramount. Industries such as automotive, manufacturing, and machinery extensively rely on TC oil seals to maintain optimal performance and reduce the risk of fluid leakage, thereby safeguarding the longevity and functionality of critical equipment. 　　TC oil seals are widely used in various industries to prevent fluid leakage and contamination, contributing to the overall efficiency and reliability of machinery and equipment. Understanding the meaning and implications of TC in skeleton oil seals enables industries to make informed choices when selecting the appropriate sealing solution for their specific applications.

Combine the conveyor belt to transport eggs for printing, and reserve holes in the conveyor belt design so that each egg can be placed and fixed on the hole. The eggs are transported forward on the conveyor belt at a set speed. When the sensor detects the egg signal, the relevant information is printed on the surface of the egg. Coding in the egg industry: Printing all kinds of clear information on the surface of the egg to realize the code traceability of the egg product can allow consumers to know the source and quality of the egg clearly when buying eggs, increase consumer confidence, and enhance brand awareness.More and more attention is paid to egg safety. With the continuous enhancement of safety awareness and the continuous implementation of relevant laws and regulations, there are higher requirements for the label of the egg industry.Therefore, we provide a complete set of reliable egg coding solutions.

S400PLUS Continuous Inkjet Printer Continuous Inkjet Printer: Easy operation with 10.1"large screen One-key start and stop precise control Independent module maintenance is simple Automatic cleaning to prevent clogging Classic ink circuit is stable and reliable Continuous inkjet printers work by spraying strictly controlled ink particles onto the target to form clear and long-lasting marks. Inkjet printers are roughly divided into two categories: printers connected to office or home PCs, and continuous inkjet (CIJ) printers used in factory production lines. KEYENCE's MK-G series is a continuous inkjet (CIJ) printer, which is mainly used to print expiration date, batch number, barcode/2D code on products in factories and warehouses. Due to the non-contact nature of inkjet printing, blur and product damage are essentially avoided. This technology can print at high speed from any direction or direction, and the compact print head can be easily installed on the packaging machine or filling machine, making the installation process easy and free. Continuous inkjet printers (CIJ) operate by ejecting precisely controlled ink droplets onto primary packaging such as cans, bottles, films and all other forms of primary packaging substrates. These codes are used to print the expiration date, otherwise called the best expiration date and batch number, production information or bar code.
