The Role Of Graphite In Friction Materials
D465 brake pads with different graphite content were pressed by dry powder metallurgy, and the effects of artificial graphite on the properties of friction materials were studied by LINK inertial bench test. The results show that artificial graphite has little effect on the physicochemical and mechanical properties of friction materials. With the increase of artificial graphite content, the friction coefficient of friction materials decreases gradually, and the wear amount decreases first and then increases. The effect of artificial graphite on the noise occurrence of friction materials also presents the same trend. According to the comparison of physical and chemical properties, mechanical properties, friction coefficient and wear data, the friction material has the best friction and wear performance and noise performance when the content of artificial graphite is about 8%.
In the production process of raw materials after high temperature graphitization and purification treatment, high purity, high degree of graphitization of artificial graphite is easier to form a transfer film on the friction material and the dual surface, its wear reduction performance is excellent;
Less impurity content: does not contain silicon carbide and other hard particles that can produce noise and scratch the surface of the pair;
Q1. What is your main product?
We mainly produce high purity flake graphite powder,expandable graphite ,graphite foil ,and other graphite products. We can offer customized according to customer's specific demand.
Q2: Are you a factory or trading company?
We’re factory and has the independent right of export and import.
Q3. Can you offer free samples?
Usually we can offer samples for 500g, if the sample is expensive, clients will pay the basic cost of the sample. We do not pay the freight for the samples.
Q4. Do you accept OEM or ODM orders?
Sure, we do.
Q5. How about your delivery time?
Usually our manufacture time is 7-10 days. And meanwhile it takes 7-30 days to apply the Import and export license for dual-useitems and technologies, so the delivery time is 7 to 30 days after payment.
Q6. What is your MOQ?
There is no limit for MOQ, 1 ton is also available.
Q7. What is the package like?
25kg/bag packing,1000kg/jumbo bag, and we pack goods as customer's requested.
Q8: What is your terms of payment?
Usually, we accept T/T, Paypal, Western Union.
Q9: How about transportation?
Usually we use express as DHL, FEDEX, UPS, TNT, air and sea transportation is supported. We always choose economist way for you.
Q10. Do you have after-sale service?
Yes. Our after-sales staff will always stand by you, if you have any questions about the products, please e-mail to us, we will try our best to solve your problem.
