Detailed description

White PTFE 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. Competitions are not allowed pollution is mainly used for environmental sanitary conditions, corrosion, etc., the line speed is high, easy to wear and other conditions.

Q: Silicone rubber gasket can withstand acid and alkali corrosion?: 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: I found that the hydraulic joint can be used as a gasket with an aluminum pad or a copper pad, and the effect is good, but I don't know if there will be any other effect after repeated disassembly or long serviceImports of hydraulic equipment in the middle of some even no sealing ring, but spent more than ten years will not leak, but after opening and then installed on the failure, why?: The metal pad before using the best grinding, long time use is also good, but now the popular seal combination, inside is rubber, the outer ring is a metal skeleton, but also the price is disposable, and metal pad almost.

Q: Gasket is a kind of machinery, equipment, pipes and other internal sealing materials, which types are there?High and medium pressure asbestos rubber sheet gasket, oil asbestos rubber gasket, cylinder gasket, aramid gasket, non asbestos plate gasket, asbestos pad, PTFE lining rubber pad, I know that, there are other ones?Can anyone tell me what their scope of application is?: The new organization dense, molecular structure of non-polar, used as a gasket, contact surface can be smooth, the metal flange is not sticky. In addition by molten alkali metal and containing fluorine gas erosion, which is resistant to many kinds of acid and alkali, salt, oil solution of corrosive media. PTFE gasket including pure PTFE, PTFE or PTFE expansion. The semi metallic gasket (also called metal gasket). Non metallic material has good flexibility, compression and bolt load ability is low. But it is mainly to determine the strength is not high, poor elasticity, not suitable for high pressure temperature. So the combination of metal materials with high strength and good elasticity. Withstand high temperature characteristics. The formation structure is semi metal gasket. The gasket. Semi metal gasket are mainly metallic gasket, metal winding gasket, corrugated metal gasket, with metal serrated gasket with the metal. Gasket (metal gasket). The gasket to nonmetal material core, thickness of sheet metal 0.25-0.5mm outsourcing. According to the state of coating can be divided into coating, coating, coating and half wave Double coated sheet metal. According to the elastic-plastic material, heat resistance and corrosion resistance were selected. Mainly copper, galvanized iron, stainless steel, titanium, Monel alloy. It is widely used in copper, galvanized iron, stainless steel.

Q: What material flange gasket is better on the steam pipe?: Answer two: I think there is a problem of flange pressure rating is not high enough to design such as 150LB standard commonly used on soft flat gaskets, pressure rating of more than 300LB to recommend the use of metal winding pads I very strange, because the wound pad cheap?? Flange bolt torque low level is low and the corresponding metal winding pads need enough pressure to achieve the sealing effect, there is a low level of flange used to seal the torque, or not enough preload force is not up to the general effect of the former, or to recommend the use of inorganic fiber gasket, metal wound gasket......

Q: Method for using gasket free sealant: Remove the greasy dirt, moisture, rust and dust on the glued surface, and keep the bonding surface clean and dry;Apply the glue to the surface of the adhesive and coat it into an unbroken rubber ring (which needs glue around the screw hole);The airing glue is about 10 to 15min. After the table is dried, the bolt is fastened and fastened according to the requirement of use;After the glue, should be placed more than 24h, after the glue curing, forming an elastic gasket.

Q: Figure 3 gear pump in the rubber seal gasket, draw the assembly plan, you need to draw the gasket out? How thick is the painting? The graph doesn't give it the relevant size.: Drawing assembly drawings must be drawn at the same time indicate the gasket, the standard number, because the regular assembly drawing shall also have the parts list, those parts need to be purchased, which is homemade, and so on, at a glance, as the thickness of the gasket, with the actual size picture, otherwise it will affect the length of the shaft and fixed bolt.

Q: How do you get that washer in the lid of the beauty cooker?: but cover the inner layer and the outer layer is stuck together, can be directly used to pry open the nail make a gap in the insert screwdriver with slight force can put the inner layer and the outer layer separated (to pry a circle, before trying to cover the pot with a long screw connecting part down, otherwise open in the cover, can not take off, also cannot be separated with metal parts in the cover layer).

Q: How can I remove the stains from the rubber washer on the blender? How can I remove the stains from the rubber washer on the blender? Because it is the entrance, so I dare not use 84 disinfectant.: Very good ah, the old section of the first set of good machine rubber ring, then the iron circle, 2 at the bottom of the card into the mouth on the line.

Q: Why should the washer be fitted when the screws are installed?: Used to protect the surface of the connecting piece from the scratch of the nut and to distribute the pressure of the nut on the connecting piece

Q: Is the O ring sealed or the gasket sealed?: Generally, the O ring is well sealed. However, there is a need to distinguish between the use of the environment.
