Detailed description

PTFE woven aramid fiber packing

PTFE as the main material. Has excellent chemical stability, corrosion resistance, sealing, lubrication is not high viscosity and good aging endurance. Long-term work at a temperature of -180 ℃ to +250 ℃, in addition to the molten metal and liquid sodium fluoride, the ability of all other chemicals, boiling water is not from the king of change. The following are not allowed pollution is mainly used for environmental sanitary conditions, corrosive and other demanding, high-speed lines, easy to wear and other conditions.

Q: Silicone rubber gasket can withstand acid and alkali corrosion?: Silicone rubber has excellent heat resistance, cold resistance, dielectric properties and ozone resistance and ageing resistance properties, outstanding performance of silicone rubber is the use of wide temperature, at -60 DEG C (or lower temperature) to +250 DEG C (or higher temperature) under long-term use. But the tensile strength and resistance the tear strength and poor mechanical properties of silicone rubber at room temperature, the physical and mechanical properties than most synthetic rubber, and in addition to silicone, silicone rubber, silicone rubber general oil resistance, solvent resistance is poor, so the silicon rubber should not be used for the general conditions of the occasion, but very suitable for many special occasions

Q: What's the difference between the gasket and the washer?: Gaskets (gasket) are mechanical seals between two bodies, usually used to prevent pressure, corrosion, and natural heat expansion, cold contraction and leakage between two bodies. Because machined surfaces are not perfect, gaskets can be used to fill the irregularity. Gaskets are usually made of sheet materials such as cushion paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass or plastic polymers (such as Teflon).

Q: Is PTFE gasket poisonous to human body? Do I want to use it as a sealing ring in water cup?: A few years ago reported non stick pan, add inside a layer of Teflon (PTFE), at high temperature (180 degrees Celsius) when heated to a certain extent will release hydrogen fluoride gas, soluble in water to form hydrofluoric acid, it is toxic. But your cup pad can be assured.

Q: Where is the three yuan catalyst sealing inspection machine?: Three yuan catalyst special sealing inspection machine should not sell, domestic can produce three yuan catalytic converter manufacturers can be counted, so even if there is the production of this equipment manufacturers, a year also can't sell several units;

Q: How do I remove the rubber sealing washer for the washer inlet valve?: but if it is often blocked I advise you to learn I simply to filter down (with a screwdriver destructively removed), save a lot of trouble, there is not much significance for water filtration net valve washing machine, it is brought to us is the dirty block, personal opinions for reference only.

Q: What can replace the car oil screw gasket?: Hello, you can use aluminum or copper circles, soft point!! There's something wrong with the car. Ask the car master. 4S shop professional technicians, 10 minutes to solve. ]

Q: why some bottles do not use this design, but also cumbersome gasket is not strong, 10Plastic cola bottle cap that can withstand the pressure but also how some bottle washer washer tedious sometimes not tight Ning why this design also Water Leakage generally used in cola and other bottles of mineral water bottles can also be used or patent restrictions: There are no patent restrictions, even if there is a time limit

Q: What does the UN in the seal ring stand for?: UN represents the shaft bore seal, and the UN seal is as high as the two sealing lips

Q: Explosion proof thread box plus GASKET?: It is not the key to add or not to encrypt the sealing ring, mainly to see if your cable can be sealed to meet the requirements of protection and to prevent the pulling of certain torque.

Q: and it's OK to forget to put the sealing ring when changing!: Hello, the built-in gasoline filter, then you can not install the sealing ring, it will relieve pressure, such as bad start the car does not speed up the kind of problem, I wish you a happy life [car problems, ask the car master. 4S shop professional technicians, 10 minutes to solve. ]
