Polytetrafluoroethene,incamake:PTFE
Izina ry'irindi zina: PTFE, tetrafluoroethylene, pulasitiki ikomeye, F4.
Ibyiza bya PTFE
PTFEni pulasitiki yihariye y’ubuhanga, ubu ni ibikoresho birwanya ingese, bizwi ku izina rya "umwami wa pulasitiki". Ibintu by'ingenzi biranga ni ubudahangarwa bw'ubushyuhe bwinshi n'ubuke, ubudahangarwa bw'ingese, ubushyuhe bwinshi, ubudasaza, no kwisiga amavuta.
Ikoreshwa mu by’indege, ibikoresho by’ikoranabuhanga n’amashanyarazi, inganda z’ibinyabutabire, imashini n’ibikoresho, ibiribwa n’ubuvuzi, ipompo, amabati n’imiyoboro, imodoka n’amato, imashini zikora umwuka, n’ibindi, kandi yabaye igikoresho cy’ingenzi mu gukemura ikoranabuhanga ry’ingenzi mu nganda zigezweho.
Atomu za PTFE zidafite ubushobozi bwo kurinda no kurinda umugozi wa CC, kandi ingufu za CF zo guhuza zirahamye cyane, uruhererekane rwa molekile ruragoye gusenywa, ni imiterere ihamye cyane. Iyi miterere ya molekile inasobanura imiterere myiza ya PTFE ikurikira.
Ubudahangarwa bw'inkongi:Uretse ibyuma bya alkali byashongeshejwe n'ibindi bintu bike bishongesha nk'ibinyabutabire bya alkane byose biri hejuru ya dogere selisiyusi 300, birwanya ingese y'igihe kirekire n'ibindi bintu byose bikomoka ku ruganda.
Irwanya ubushyuhe buri hejuru n'ubuke: ishobora gukoreshwa igihe kirekire kuri -60+260℃.
Amavuta menshi:igipimo gito cyane cy'ubushyamirane hagati y'ibikoresho bikomeye, ndetse n'urubura ntirushobora kugereranywa narwo.
Kudafata neza:Ubushyuhe buke cyane hagati y’ibikoresho bikomeye, ntibufatana n’ikintu icyo ari cyo cyose.
Ubudahangarwa bw'ikirere:Imyaka myinshi yo gusaza mu bya pulasitiki.
Ntabwo ari uburozi:Ibikoresho bishobora gukoreshwa nk'imitsi y'amaraso y'ubukorano, idahumanya kandi idatera allergie n'izindi ngaruka mbi, mu bikoresho byo mu rwego rw'ibiribwa n'imiti.
Imiterere y'ubushyuhe:Filime nini nk'ikinyamakuru irahagije kugira ngo irwanye amashanyarazi afite ingufu nyinshi za volti 1500.
Byongeye kandi, PTFE ntabwo ifata ubushuhe, ntishobora gushya, kandi ikunda cyane ogisijeni n'urumuri rwa ultraviolet.
Ingaruka mbi za PTFE
Nubwo PTFE ifite imikorere myiza cyane, ariko imbaraga nke za mashini, ingano nini y’ubunini bw’umurongo, ubwiyongere buke bw’ubushyuhe, ubwiyongere buke bw’ubushyuhe n’ibindi bibazo. Mu mbaraga za mashini n’ibindi bibazo bigoye, nko gukoreshwa mu nganda zifunga valve kandi ntarengwa yo gukoresha neza ubushyuhe muri rusange buri hagati ya -70 ~ +150℃. Kugira ngo ibyo bibazo bitsindwe, resin ya PTFE ishobora kuzuzwamo ibintu bikomeza imbaraga kugira ngo inoze imiterere ya mashini y’ibikoresho, kugira ngo yongere ubushobozi bwo gukoresha ibikoresho byayo.
Intangiriro ku miterere ya PTFE y'amabara
Ibara ry'umwimerere rya PTFE ni ibara ry'umweru usa n'amata, mu gihe ibara rya PTFE ari uko ibikoresho by'ibanze bya PTFE byuzuyemo ibikoresho by'inyongera. Ibikoresho by'inyongera bishobora kugabanywamo ibyiciro bibiri hakurikijwe ikoreshwa: ibikoresho byo kongera imbaraga n'ibikoresho by'ifu y'amabara.
Icyiciro cy’ibikoresho by’ifu y’amabara: cyuzuyemo ifu y’amabara muri PTFE, gishobora kuba umukara, umuhondo, umutuku, icyatsi kibisi, ubururu n’ibindi. Ibikoresho by’ifu y’amabara bigamije guhindura ibara rya PTFE gusa, igipimo cy’ibiruzuza ni gito bityo ingaruka z’imikorere ya PTFE y’umwimerere zishobora kwirengagizwa. Mu buryo bw’imitekerereze, ibikoresho by’ifu y’amabara bigomba kugira ingaruka ku buryo PTFE iguma mu buryo buhamye, ku buryo irinda ubushyuhe, imbaraga zo gukurura n’izindi miterere y’imashini. Kubwibyo, hari ibihe byihariye bigomba kumenyekana. PTFE y’amabara ihura n’ibyo abakiriya bakeneye ku birebana n’amabara agaragara.
Kugura umuyoboro wa PTFE ukwiye ntabwo ari uguhitamo gusa ibipimo bitandukanye ku bikorwa bitandukanye. Byinshi ni uguhitamo uruganda rwizewe.BesteflonIndashyikirwa za fluorine plastic Co., Ltd. zihariye mu gukora ibikoresho by’ubuziranengeImiyoboro ya PTFEn'imiyoboro y'amashanyarazi mu gihe cy'imyaka 20. Niba hari ibibazo n'ibyo ukeneye mu miyoboro y'amashanyarazi ya ptfe, nyamuneka tubwire inama z'inzobere.
