PTFEuye kabhoni fiber haisi chinhu chimwe chete.Nhasi, tichakuzivisai zvinhu zviviri izvi.
PTFE ipurasitiki ine fluorine, inozivikanwawo seTeflon, Teflon, nezvimwe.PTFE plastikiinozivikanwawo seMambo wePlastiki nekuda kwekuita kwayo kwepamusoro mumativi ese.PTFE inogona kuramba corrosion, yakakwirira uye yakaderera tembiricha, haina chepfu, yakanakisa insulation, anti-kuchembera, mafuta ekuzora, uye zvimwe zvakanakisa zvivakwa.Zvisinei, pane zvinhu zvakawanda zvinoda kuvandudzwa, zvakadai sokukambaira, kusadonhera, kupikisa abrasion, kuputika kwemutsara uye kudzvinyirira kuramba, kuoma uye zvichingodaro.Kuti uwedzere kuvandudza zvinhu izvi zvePTFE, zvimwe zvinhu zvakadai se molybdenum disulfide, girasi fiber, graphite, polyphenylene resin, girazi fiber, uye simbi yehupfu zvinogona kuwedzerwa kune raw material yePTFE muhuwandu.Kuwedzerwa kwekabhoni fibers inzira yakajairika yekushandura PTFE zvigadzirwa.Basa rekabhoni fiber mukuzadza PTFE nderekuwedzera kukambaira kuramba, kuremerwa kwemutoro, kupfeka kuramba, kugadzikana kwedimensional, kusimba simba uye zvimwe zvinhu zve.PTFE inoshandisa.
Carbon fiber (CF for short) rudzi rutsva rwefiber material ine simba rakawanda uye yakakwira modulus ine inodarika 95% kabhoni.Iyo microcrystalline graphite zvinhu zvakagadzirwa ne organic fibers senge flake graphite microcrystals akaturikidzana mune axial kutungamira kwemafiber, ayo anogadziriswa necarbonization uye graphitization.Carbon faibha "yakapfava kunze asi yakaomarara mukati", yakareruka muhuremu kupfuura aruminiyamu asi yakasimba kupfuura simbi, uye ine hunhu hwekusaita ngura uye yakakwirira modulus, zvichiita kuti ive chinhu chakakosha mune zvese zvekudzivirira uye zvechivanhu.Haisi chete ine inherent intrinsic zvimiro zvekabhoni zvinhu asiwo ine kupfava uye kugadzirisika kwemachira machira, zvichiita kuti ive chizvarwa chitsva chekusimbisa fiber.Carbon fiber ine zvakawanda zvakanakisa zvivakwa.Iyo ine yakakwira axial simba uye modulus, hapana inokambaira, yakanaka kuneta kuramba, chaiyo kupisa uye magetsi conductivity pakati isiri-simbi nesimbi, uye yakanaka electromagnetic kudzivirira.Iyo coefficient yekuwedzera kwekupisa idiki, corrosion resistance yakanaka, kuwanda kwemafiber kwakadzikira, X-ray permeability yakanaka, huremu hwakareruka, uye nharaunda isiri-oxidizing inoshingirira kune tembiricha yakanyanya.Kuenzaniswa neyakajairwa girazi fibers, kabhoni fiber ine kanopfuura katatu Young's modulus.Kuenzaniswa neKevlar, Young's modulus inosvika zvakapetwa kaviri pakukwirira, uye hainyunguriki uye yakazvimba muorganic solvents, acids uye alkalis, uye ine yakasarudzika corrosion resistance.Kuwedzerwa kwekabhoni fiber kunonatsiridza zvikuru kutakura-kuremerwa kwehuwandu hwezvinhu zvakasanganiswa, uye chidimbu chemagirafu chinowedzerwa panguva imwe chete sePTFE pamwe nekuzadza zvinhu carbon fiber.Kuwedzerwa kwe graphite kunoderedza coefficient of friction pakati pekabhoni fiber pamusoro pepamusoro uye mutevedzeri, nokudaro kuderedza tsika yekabhoni fiber kudonha uye kuvandudza kusagadzikana kwekupfeka kwezvinhu zvakasanganiswa.
