Category: Polytetrafluoroethylene (PTFE) Qalabka Teflon
Polytetrafluoroethylene (PTFE) waa fluoropolymer synthetic ee tetrafluoroethylene kaas oo leh codsiyo badan sababo la xiriira sifooyinka gaarka ah. Waxa si shil ah u helay sannadkii 1938 kii farmashi yaqaan la odhan jiray Roy Plunkett isaga oo ka shaqaynayay samaynta qaboojiye cusub. PTFE Waxaa caadi ahaan loo yaqaan magaca astaanta ah ee Teflon, oo ay iska leedahay shirkadda kiimikada DuPont.
PTFE waa shay aan firfircoonayn oo kuleyl ahaan deggan oo adkaysi u leh inta badan kiimikooyinka, oo ay ku jiraan asiidhyada iyo saldhigyada. Waxay leedahay iskudhaf aad u hooseeya oo iskuxiran, taas oo ka dhigaysa doorasho aad u fiican oo loo isticmaalo codsiyada halka la rabo khilaaf hooseeya, sida xirmooyinka iyo shaabadeynta. PTFE sidoo kale waa dahaye koronto oo heersare ah, taasoo ka dhigaysa mid faa'iido u leh codsiyada korantada.
Mid ka mid ah codsiyada ugu caansan ee PTFE ayaa ku jira weelka wax lagu karsado ee aan dhegta lahayn. Guryaha aan dhegta lahayn ee PTFE waxaa sabab u ah tamarta korkiisa oo yar, taas oo ka hortagaysa in cuntadu ay ku dhegganaato dusha sare ee qalabka wax lagu kariyo. PTFE Waxa kale oo loo adeegsadaa codsiyada kale ee guryaha aan dhejiska ahayn ee la doonayo, sida dahaarka aaladaha caafimaadka iyo soo saarista gaasaska iyo shaabadihii.
PTFE waxaa sidoo kale loo isticmaalaa warshadaha hawada sare sababtoo ah iska caabbinta heerkulka sare iyo isku-dhafka hoose ee isku-dhafka. Waxa loo adeegsadaa soo saarista qaybaha matoorada diyaaradaha, sida shaabada iyo xadhkaha. PTFE waxaa sidoo kale loo isticmaalaa in dhismaha ku habboon meel bannaan oo ay sabab u tahay awoodda ay u leeyihiin in ay u adkeysan heerkulka xad-dhaaf ah iyo sifooyinkiisa aan dhejis ahayn.
Waxa u dheer isticmaalkeeda dahaarka aan dhegta lahayn iyo codsiyada hawada sare. PTFE Waxa kale oo loo isticmaalaa soo saarista alaabooyin kale oo kala duwan, sida fiilooyinka kombuyuutarka, qaybaha baabuurta, iyo dahaarka warshadaha. Waxaa sidoo kale loo isticmaalaa soo saarista dharka Gore-Tex, taas oo ah wax aan biyuhu lahayn oo neefsan kara oo loo isticmaalo dharka iyo kabaha dibadda.
Gabagabadii, PTFE waa walxo kala duwan oo leh sifooyin gaar ah oo ka dhigaya mid faa'iido u leh codsiyo kala duwan. Dabeecaddeeda falcelin la'aanta ah, isku-dhafka hooseeya ee isku-dhafka, iyo iska caabbinta heerkulka sare ayaa ka dhigaysa doorasho aad u fiican oo loo isticmaalo daahano aan dhejis ahayn, qaybaha hawada hawada, iyo codsiyada kale ee warshadaha.
