Recently,
Michelin tires and
Amiris signed an agreement, Michelin and Amilis will jointly fund and will combine the technical resources of both parties to develop
renewable rubber matrix isoprene .
Amiris expects that the rubber matrix will be available for use in tires or other special applications such as adhesives, coatings, and sealants in 2015. Michelin promised to purchase the rubber matrix on a 10-year basis. In addition, Armies has the right to sell the rubber matrix to other customers.
It is understood that the traditional isoprene production method is usually naphtha thermal decomposition or C4 steam synthesis. Amiris recently discovered that farnesene (C15H24) also converts sugars to isoprene (C5H8). Isoprene, a renewable rubber matrix, will be the base material for rubber tires and other rubber products.
Extensive reading:
Isoprene is an important monomer for synthetic rubber. It is mainly used for the synthesis of isoprene rubber. Its production is second only to styrene-butadiene rubber and butadiene rubber and ranks third in synthetic rubber. In recent years, isoprene has been used to synthesize linalool, squalene and the like, which are further intermediates for synthesizing perfumes, pharmaceuticals, and agricultural chemicals.
Renewable rubber is a rubber that has a certain degree of plasticity and can be reused, which has been processed from vulcanized corner wastes in the production of rubber products. Abbreviated reclaimed rubber. According to different waste rubber used, reclaimed rubber is classified into outer casings, inner tubes, and rubber shoes. Reclaimed rubber can partially replace raw rubber for rubber products, so as to save raw rubber and carbon black, it is also beneficial to improve processing performance and certain properties of rubber products. Brake Pads
Brake pads convert the kinetic energy of
the vehicle to thermal energy through friction. Two brake pads
are contained in the brake caliper, with their friction surfaces facing
the rotor. When the brakes are hydraulically applied, the
caliper clamps or squeezes the two pads together onto the spinning rotor to
slow and stop the vehicle. When a brake pad heats up due to contact with
the rotor, it transfers small amounts of its friction material onto the
disc, leaving a dull grey coating on it. The brake pad and disc (both now
having the friction material), then "stick" to each other, providing
the friction that stops the vehicle.
In disc brakes, there are usually two brake pads per disc rotor.
These are held in place and actuated by a caliper affixed to the wheel hub
or suspension upright. Racing calipers, however, can utilize up to
six pads, with varying frictional properties in a staggered pattern for optimum
performance. Depending on the properties of the material, the weight of the
vehicle and the speeds it is driven at, disc wear rates may vary. The brake
pads must usually be replaced regularly (depending on pad material) to prevent
brake fade. Most brake pads are equipped with a method of alerting the driver
when this needs to be done. A common technique is manufacturing a small central
groove whose eventual disappearance by wear indicates the end of a pad's
service life. Other methods include placing a thin strip of soft metal in a
groove, such that when exposed (due to wear) the brakes squeal audibly. A soft
metal wear tab can also be embedded in the pad material that closes an electric
circuit when the brake pad wears thin, lighting a dashboard warning light.
