Ingabe i-PTFE iyafana ne-carbon fiber?

I-PTFEkanye ne-carbon fibre akuyona into efanayo.Namuhla, sizokwethula lezi zinto ezimbili.

I-PTFE iyipulasitiki equkethe i-fluorine, eyaziwa nangokuthi i-Teflon, i-Teflon, njll.Ipulasitiki ye-PTFEyaziwa nangokuthi iNkosi Yepulasitiki ngenxa yokusebenza kwayo okuphezulu kuzo zonke izici.I-PTFE ingamelana nokugqwala, amazinga okushisa aphezulu naphansi, ayinobuthi, i-insulation enhle kakhulu, i-anti-aging, i-lubrication ephezulu, nezinye izakhiwo ezinhle kakhulu.Kodwa-ke, kunezindawo eziningi ezidinga ukuthuthukiswa, njengokukhasa, ukungagxili, ukumelana nokuhuzuka, ukuvuvukala komugqa nokumelana nokucindezela, ubulukhuni nokunye.Ukuze kuthuthukiswe lezi zakhiwo ze-PTFE, ezinye izinto ezifana ne-molybdenum disulfide, i-glass fibre, i-graphite, i-polyphenylene resin, i-glass fibre, kanye nempushana yensimbi ingangezwa kumpahla eluhlaza ye-PTFE ngokulingana.Ukwengezwa kwe-carbon fibers kuyindlela evamile yokuguqula imikhiqizo ye-PTFE.Indima ye-carbon fibers ekugcwaliseni i-PTFE ukukhulisa ukumelana nokukhasa, ukumelana nomthwalo, ukumelana nokugqoka, ukuzinza kwe-dimensional, amandla aqinile kanye nezinye izakhiwoI-PTFE isebenzisa.

I-Carbon fiber (i-CF ngamafuphi) iwuhlobo olusha lwe-fiber material enamandla amakhulu kanye ne-modulus ephezulu equkethe ngaphezu kuka-95% wekhabhoni.Kuyi-microcrystalline graphite material eyenziwe ngemicu ephilayo efana ne-flake graphite microcrystals enqwabelene ekuqondeni kwe-axial ye-fibers, ecutshungulwa yi-carbonization kanye ne-graphitization.I-carbon fibre "ithambile ngaphandle kodwa iqinile ngaphakathi", ilula ngobuningi kune-aluminium kodwa inamandla kunensimbi, futhi inezici zokumelana nokugqwala kanye ne-modulus ephezulu, okuyenza ibe yinto ebalulekile kukho kokubili ukuvikela kanye nezicelo zomphakathi.Ayinayo nje kuphela imvelo yemvelo yezinto zekhabhoni kodwa futhi inokuthamba nokucutshungulwa kwemicu yendwangu, okuyenza ibe isizukulwane esisha semicu eqinisayo.I-Carbon fiber inezakhiwo eziningi ezinhle kakhulu.Inamandla aphezulu e-axial kanye ne-modulus, akukho ukukhasa, ukumelana nokukhathala okuhle, ukushisa okukhethekile kanye nokuhamba kukagesi phakathi kokungeyona insimbi nensimbi, kanye nokuvikela okuhle kwe-electromagnetic.I-coefficient yokwanda okushisayo incane, ukumelana nokugqwala kuhle, ukuminyana kwemicu kuphansi, ukufinyeleleka kwe-X-ray kuhle, ubukhulu bulula, futhi indawo engeyona i-oxidizing imelana nokushisa okuphezulu kakhulu.Uma kuqhathaniswa nemicu yengilazi evamile, i-carbon fibre inemodulus ye-Young izikhathi ezingaphezu kwezintathu.Uma iqhathaniswa ne-Kevlar, i-Young's modulus iphakeme ngokuphindwe kabili, futhi ayincibiliki futhi ivuvukele kuzinyibilikisi zemvelo, ama-asidi nama-alkali, futhi inokumelana nokugqwala okuvelele.Ukwengezwa kwe-carbon fiber kuthuthukisa kakhulu umthamo othwala umthwalo wezinto ezihlanganisiwe, futhi inani elincane le-graphite lengezwa ngesikhathi esifanayo ne-PTFE kanye ne-fiber material yokugcwalisa.Ukwengezwa kwe-graphite kunciphisa i-coefficient of friction phakathi kwe-carbon fibre surface kanye nozakwabo, ngaleyo ndlela kunciphisa ukuthambekela kwe-carbon fiber ukuwa futhi kuthuthukise ukumelana nokugqokwa kwezinto ezihlanganisiwe.
