Q:What are the better domestic rubber parts, seals ah?
Used are imported materials, whether it is pre-sale or after-sale cooperation degree is relatively high. There is no quality problem
Q:How should the piston rings for piston wear be chosen? What is the national standard?
Two, HNBR hydrogenated nitrile rubber sealing ring: with excellent corrosion resistance, tear resistance and compression deformation characteristics, ozone resistance, sun resistance, weather resistance better. Better abrasion resistance than nbr. The utility model is suitable for washing machines, automobile engine systems and refrigeration systems using new environmental protection refrigerant R134a. Not recommended for use in alcohols, esters, or aromatic solutions. The general use temperature range is -40~150 degrees centigrade.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.
Q:Requirements for storage of rubber seals
2, prohibit the rubber seals stored in ventilated damp place; 3, away from the heat source; 4, prohibit heavy pressure, lest deformation. 5, static and organic solvent mixing and so on.
Q:Mechanical seals do not refuel, can not?
If the sealing ring, then choose ethylene propylene rubber as auxiliary seals. Do not connect with mineral oils or fats. Other lubrication and other things are to reduce friction, good installation is not easy to damage the sealing ring
Q:The seal of the front end of the cylinder and the cylinder, "O" ring, why has it been serrated for some time?,
1., your O ring quality is not good, that is, the process and material problems.2. may be the contact material of your O ring, causing it to wear out
Q:How to use graphite seals?
The noun you said is inaccurate. Seals containing graphite mainly include graphite as sealing rings and flexible graphite as auxiliary seals. The former may be closer to what you want.
Q:So in today's world, mechanical seal is the most important shaft seal in these equipment. The mechanical seal is also called the seal, in the relevant national standard is defined as: "by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or magnetic) device and the role of the coordination of auxiliary seals to keep up with the relative sliding to prevent fluid leakage. "
Regarding the submitted APS examination materials, if you do not have the time to notarization, you may try to issue bilingual seals to the University, instead of notarization!High school diploma can also be issued to the high school!
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.
Q:Would you like to ask what glue can be used for vacuum seals?
The sealant can resist high temperature, corrosion, vacuum to achieve, you can check online, Varian was acquired by Agilent, do not know not to change the name! But for vacuum seals, there should be no problem!
Q:Aging test report of rubber sealThat is to say, rubber sealant is how anti-aging
Knowledge about aging of rubberFirst, what is rubber aging? What are the manifestations on the surface?Rubber and rubber products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the physical and chemical properties and mechanical properties of rubber gradually deteriorated, and finally lose value, this kind of change is called aging of rubber. On the surface for cracking, sticking, hardening, softening, pulverization, discoloration, mildew etc. What are the two. And the influencing factors of rubber aging?
