Amakuru - PTFE isobanura iki

Polytetrafluoroethylene (PTFE), ikaba ari ubwoko bw'ibinyabutabire byinshi, ifite ubushobozi bwo kudahinduka no kwangirika. Ni kimwe mu bikoresho byiza cyane birwanya kwangirika ku isi muri iki gihe. Uretse sodium ishongeshejwe na fluorine y'amazi, ishobora kwihanganira ibindi binyabutabire byose. Ntizahinduka nyuma yo guteka mu mazi. Ikwirakwizwa cyane mu bikoresho bitandukanye bisaba kwangirika ku bintu bishongesha aside, alkali na organic), Gufunga, amavuta menshi kandi ntafata, amashanyarazi akingira gusaza no kwihanganira gusaza neza, ubushyuhe bwiza (ishobora gukora ku bushyuhe bwa +250℃ kugeza -180℃ igihe kirekire). Noneho reka turebe neza imiterere itandukanye y'iki gikoresho n'ikoreshwa ryacyo.

Umuyoboro wa PTFEikorwa no gutunganya cyangwa gusohora amazi; ishobora kandi gukorwamo amazi akwirakwizwa kugira ngo irangirwe, inyuzwe cyangwa ikore imigozi. Polytetrafluoroethylene ikoreshwa cyane mu nganda nka za kirimbuzi, uburinzi bw'igihugu, indege, ibikoresho by'ikoranabuhanga, amashanyarazi, imiti, imashini, ibikoresho, ibyuma, ubwubatsi, imyenda, ubuvuzi bw'icyuma, imiti, ubuvuzi, imyenda, ibiryo, ibyuma n'imashini ishongesha, nibindi, ibikoresho birwanya ingese, ibikoresho bikingira ubushyuhe, irangi rirwanya uduce duto, nibindi, bigatuma iba ikintu kidasimburwa. PTFE ifite imiterere myiza cyane, irwanya ubushyuhe bwinshi, irwanya ingese, idafata, yisiga amavuta, imiterere myiza ya dielectric, n'umuvuduko muto cyane w'ubushyuhe. Ikoreshwa nk'imashini zikora ubwubatsi, ishobora gukorwamo imiyoboro ya PTFE, inkoni, imikandara, amasahani, filime, nibindi. Muri rusange ikoreshwa mu miyoboro irwanya ingese, ibikoresho, pompe, valves, radar, ibikoresho by'itumanaho bipima inshuro nyinshi, n'ibikoresho bya radiyo bifite imikorere myiza. Iyo wongeyeho icyuma cyose gishobora kwihanganira ubushyuhe bukabije bwa PTFE, imiterere yayo ya mekanike ishobora kunozwa cyane. Muri icyo gihe, hari izindi ngaruka nziza za PTFE. Ubwoko bwuzuye burimo fibre y'ikirahure, icyuma, okiside y'icyuma, grafiti, molybdenum disulfide, fibre ya karuboni, polyimide, EKONOL... n'ibindi. Ubudahangarwa bw'ingufu n'agaciro ntarengwa ka PV bishobora kwiyongeraho inshuro 1000.

ItsindaUmuyoboro wa PTFEIkozwe muri resin ya polytetrafluoroethylene ikozwe muri polymer ikoresheje uburyo bwo gutunganya plunger extrusion. Muri pulasitiki izwi, PTFE ifite ubushobozi bwo kurwanya imiti n'imikorere ya dielectric. Gupakira PTFE ni ibikoresho byiza byo kuziba. Iboshywe muri kaseti ya PTFE yagutse. Ifite imiterere myiza nko kuba ifite ubushobozi buke bwo kwangirika, kudashira, kudashonga neza, kudafunga neza, kudakoresha hydrolysis, no kudakomera. Ikoreshwa mu gufunga gasket no mu bikoresho byo kwisiga bikora mu buryo butandukanye, ndetse no mu byuma bikingira amashanyarazi bikoreshwa mu buryo butandukanye. Capacitor dielectric, insulation ya cable, insulation ya electrical instrument, nibindi. PTFE filime ikwiriye insulation ya capacitor dielectrics, insinga zidasanzwe, insulation ya insinga, insulation ya electrical n'ibikoresho na gasket zo kuziba. Ishobora kandi gukoreshwa nk'ikase idafata, kase yo kuziba, no gukuraho

Ibikoresho rusange

Inkoni zitandukanye, imiyoboro, impapuro, imikandara, imigozi, imipfundikizo, gaskets, na grafiti, molybdenum disulfide, aluminium oxide, fibre y'ikirahure, na fibre ya karuboni bikoreshwa nk'ibyuzuza kugira ngo kunoze imiterere ya PTFE y'umwimerere.

Irwanya kwangirika

Ibi byavuzwe haruguru ni ibisobanuro byacu ku bicuruzwa n'inganda zikoreshwa mu bikoresho bya PTFE. Umujyi wa Huizhoubesteflon Isosiyete y'inganda ya fluorine plastic imaze imyaka 16 yibanda ku bushakashatsi n'iterambere, gukora no kugurisha imiyoboro ya PTFE ikoze neza, imiyoboro irinda imihindagurikire, imiyoboro iteranya ibintu, n'imiyoboro iteranya ibintu. Niba ushishikajwe n'ibicuruzwa byacu, twandikire.
