PTFE, inozivikanwa zviri nani sepolymer, ipolymer yakawana kukosha mukushandiswa kwemaindasitiri mukati mechikamu chechipiri chezana ramakore rechimakumi maviri.Iyo yakaderera coefficient of friction uye inertness inoita kuti ive yakakodzera kwete chete midziyo yekubika, asiwo yezvisimbiso mumavharuvhu eindasitiri.Nekudaro, izvo zvinhu zvinoratidzira zvisingadiwe zvemakanika zvinhu, sekuzorora kwekushushikana (kureva kurasikirwa kwekuomarara nenguva) uye kutsamira kwetembiricha, izvo zvinogona kukonzera matambudziko mune mamwe maapplication.
Imwe application umo PTFE yakaratidza kubatsira kune zvimwe zvinhu iri muzvisimbiso zvinoshandiswa mumaindasitiri plug mavharuvhu.Industrial plug mavharuvhu anoshandiswa kutakura mvura dzakasiyana siyana, uye nekudaro anoiswa pasi pemamiriro ekuda, akadai sekurwiswa kwemakemikari uye tembiricha yakakwira.Zvisimbiso zvinoda kusangana nezvinodiwa zvemakemikari kuramba, nepo kudzivirira kuvuza nguva dzese.Chishuvo chekudzikisa mutengo wekugadzira uku uchivandudza mashandiro atungamira mukudiwa kwezvisimbiso zvakatetepa, zvine kudiwa kwepamusoro pazvinhu.Kunzwisisa kwakanaka kwekuti zvinonetsa mukati mechisimbiso zvinogoverwa sei zvinodikanwa.Uyezve, chiitiko chekuzorora kwekushushikana uye kutsamira kwekushisa zvinofadza uye zvinofanirwa kuverengerwa zvakare, kufanotaura maitiro echisimbiso.
PTFE ndicho chinhu chinotonga chinoshandiswa kuvhara mvura mukati uye mumhepo.Chisimbiso chemukati chinopihwa nePTFE sleeveiyo yakamanikidzwa pakati pemuviri neplug, nepo kuvharirwa kwekunze kunovimbiswa nePTFE chisimbiso chepamusoro.
PTFE ipolymer yakawanikwa muna 1938 naRoy Plunkett weDuPont Company.Chimiro chayo chemakemikari chine cheni dzekabhoni maatomu akasungwa pamwechete, aine matavi emaatomu efluorine akabatanidzwa.Izvo zvinhu zvinowanzodaidzwa kunzi polytetrafluoroethylene (PTFE), nepo polymer iri chiratidzo chakanyoreswa cheDuPont Company.
PTFE yave chinhu chakakosha cheinjiniya.Mabhenefiti ayo makuru ndeayo asina-adhesive hunhu, inertness, kuramba kurwiswa kwemakemikari uye yakanyanya simba.Uyezve, chaiwo zvimiro zvemuviri zvinogona kukwidziridzwa nekuwedzera macommunitions ekuzadza kana kushandura maitiro ekugadzira.Zvimwe zvakashata zvemuviri izvo PTFE zvakasangana nazvo zvakanyanya kunzwa kune tembiricha shanduko uye kushomeka kuramba kunokambaira uye kusagadzikana kuzorora.Iyo yakaoma uye isina-mutsara chimiro cheaya maitiro anopa basa rakatetepa kune chero mainjiniya anoda kufanotaura maitiro ePTFE.
Imwe drawback iyo PTFE inotambura ndeyekunyunguduka kwayo kwakakwira kunoita kuti jekiseni uye kuvhuvhuta kusingagoneke, zvichisiya nzira dzinodhura dzekugadzira, dzakadai senge sintering uye extrusion, sarudzo dzega dzekugadzira chikamu.
