Q:What kind of material seals can withstand ammonia, -40 degrees to 200 degrees?
3, outstanding non sticky, abnormal lubrication, and excellent electrical insulation performance, aging resistance and radiation resistance, minimal water absorption and other characteristics.
Q:What are the differences between silicone rubber and butyl rubber in the use of water seals for home improvement?
Silicone rubber is superior in sealing, durability and heat resistance,
Q:What is the material of the sealing ring mostly?
Three, SIL silicone rubber sealing ring: with excellent heat resistance, cold resistance, ozone resistance, atmospheric aging resistance. Has good insulation performance. But the tensile strength is inferior to that of ordinary rubber and has no oil resistance. Applicable to household appliances, such as electric water heaters, electric irons, microwave ovens, etc.. The utility model is also suitable for various articles which have contact with human bodies, such as a kettle, a water dispenser, etc.. Not recommended for use in most concentrated solvents, oils, concentrated acids, and sodium hydroxide. The general use temperature range is -55~250 degrees centigrade.Four, VITON fluorine rubber sealing ring: high temperature resistance better than silicone rubber, excellent weather resistance, ozone resistance and chemical resistance, cold resistance is bad. They are resistant to most oils and solvents, especially acids, aliphatic hydrocarbons, aromatic hydrocarbons, and animal and vegetable oils. Applicable to sealing requirements for diesel engines, fuel systems and chemical plants. Mixtures of ketones, low molecular weight esters and nitric acid are not recommended. The general use temperature range is -20~250 degrees centigrade.
Q:What are the requirements of bearings for sealing?
Non contact seals include axial curve seals, radial bend seals, oil groove seals, retaining rings, seals, etc.
Q:Why can't polyurethane seal be used as hydraulic oil with water glycol?
Polyurethane, known as polyurethane, is a general term for macromolecular compounds containing repetitive urethane groups on the main chain. It is made up of organic diisocyanate or polyisocyanate with two hydroxyl or polyhydroxy compounds. The polyurethane material, very versatile and can replace the rubber, plastic, nylon, used in airport, hotel, building materials, automobile plant, coal plant, cement plant, Premium Apartment House, villas, garden landscaping, stone art park, etc..
Q:What are the seals? What role can they each play?
The seals are available:NBR sealant, three yuan ethylene propylene rubber seals, fluorine rubber seals, silicone seals, fluorosilicone seals, nylon seals, polyurethane seals, and engineering plastic seals.
Q:Sealing type and specification of solenoid valve core
Cage or sleeve is considered large differential pressure or high pressure or large caliber valve, is now more and more common, and can add a variety of
Q:Mechanical, I often need to use seals, when used with a sudden do not know the specifications, size,
You can go to some professional forums online to download some of the electronic version of books, such as the mechanical design manual (the new software version 2008), Handbook of mechanical design software, R2.0 version of "mechanical design manual" Mechanical Industry Press, "mechanical design manual" (Third Edition) edited by Cheng Daxian chemical Industry Press
Q:What are the differences between polyurethane TPU and CPU in cylinder seals?
Is a new type of polymeric material between rubber and plastic, in practical application, as a rubber product, because CPU has excellent abrasion resistance (the elastomer), casting polyurethane elastomer (CPU) is also called a thermosetting elastomer, at room temperature into liquid solid characteristics after processing, so CPU is often used for casting processing, such as casters, mining, refining, textile, printing machine roller, the finished product in wear resistance strong.
Q:Does the PTFE seal contain plasticizer? Does the silicone seal require temperature during use?
Polytetrafluoroethylene (Polytetrafluoroethylene), abbreviated as "PTFE", is commonly referred to as "nonstick coating" or "easy to clean material". The material has the properties of acid fast, alkali resistance and various organic solvents. It is almost insoluble in all solvents.
