PFC high-strength fabric phenolic resin is a thermosetting linear phenolic resin as base material, with high quality cotton or other fiber and its fabric as reinforced materials, and with the right amount of wear-resisting anti-friction additives, composite processed by advanced technology.
PFC high-strength fabric phenolic, because of reasonable formula and the unique production process has the superior mechanical, physical and chemical properties, and the commonly used engineering plastics such as pom, nylon, ptfe products, more excellent compression strength, hardness, thermal deformation temperature, impact resistance, self-lubricating, wear-resistant properties.
Over the years, PFC high-strength fabric phenolic products has been widely applied in engineering machine oil cylinder of the guide ring, ring, all kinds of bushing, thrust washers, bearings and other mechanical parts and components, products with excellent performance is well received by the majority of users.
Mouth high bearing capacity
PFC compared with commonly used engineering plastics, has high mechanical strength, compression strength, for example, about 2 to 4 times of that for the latter, the former shows its high bearing capacity. It compared with bronze, due to its weight is only 1/4, therefore, also has high specific strength.
High heat resistance performance
PFC compared with commonly used engineering plastics, has high thermal chemical stability and thermal mechanical stability. General engineering plastics for long-term use temperature about 80-90 ℃, and PFC can be as high as 160-180 ℃, extended the scope of use.
Good grinding down
PFC compared with bronze, hardness is low, has the good grinding smooth, easy break-in, and do not grind shaft. As a precision bearing, can be removed from the grinding process of heavy and complicated. In addition, can increase the friction pay between real contact area, also is to reduce the actual load, thereby reducing wear and tear.
The compatibility of outstanding
Due to the molecular structure of the PFC quantity is given priority to with hydrocarbon chain molecules and minerals in the similar molecular structure. Therefore, and compatibility with special hydrophilic, even in the lubrication condition has a tough situation. Such as frequent opening and closing, intermittent motion and swaying motion of friction between the pay is hard to form hydrodynamic lubrication oil film, it still can make the most of trace amounts of oil, thus greatly extend the refueling and maintenance cycle and service life.
The mouth of elastic-plastic can appropriately
PFC is a kind of elastic-plastic material. It compared with the material such as bronze, cast iron, easy to assemble, also has the function of absorbing vibration and noise, lower part in the sports impact, therefore the mechanical damage. It compared with the general engineering plastic, not easy to produce plastic deformation that affects its bearing function.
Good dimensional stability
Compared with the general engineering plastics, the linear expansion coefficient of PFC is lower about 1/2, are small compared with nylon its water imbibition. Therefore, as a part of the high dimension accuracy requirement, such as bearing of the PFC products are sexual pressure distribution and the fit clearance is relatively easy to control.
Good hydrophilic properties
Contains special additives of PFC can also has good hydrophilicity, it can under the conditions of the oil, the long-term safety work in water cooling or in the water, was a complicated set of lubrication sealing device.
PFC high-strength fabric phenol can be widely used in all kinds of mechanical friction and wear parts, such as bearings, bushings, thrust washers, guide rail and guide ring, ring, etc. All has its own features. Applicable machinery industry are: engineering machinery, mining machinery, petrochemical machinery, agricultural machinery, railway and Bridges, water and electricity engineering machinery and other industries.
