PTFE chubu - chinthu chimodzi, ntchito zingapo

Chisinthiko cha Polytetrafluoroethylene (PTFE) - kuchokera ku chinthu cha niche chomwe chimagwiritsidwa ntchito pamtengo wapamwamba kwambiri mpaka chofunika kwambiri chakhala chapang'onopang'ono.

Komabe, m'zaka makumi awiri zapitazi kugwiritsidwa ntchito kwa PTFE kukuwoneka kuti kwadutsa misa yambiri, kulola kuti ikhale yogwira ntchito pamakampani opitilira 200, ogula ndi azachipatala.Ndipo pamene mapepala, ndodo, zokutira ndi zigawo zikuluzikulu zili pakona kuchuluka kwa msika wa zinthu za PTFE, chubu cha PTFE ndi payipi ya PTFE tsopano zikutuluka ngati malo ofunikira kukula.

PTFE TUBE WOPEREKA

PTFE chubu ntchito

Kugwiritsa ntchitoPTFE chubuyafalikira pamagwiritsidwe osiyanasiyana kuphatikiza magalimoto, mankhwala, magetsi ndi zamankhwala.Gulu 1 likuwonetsa zinthu zazikulu zomwe zikuwonetsa kusinthasintha kwa chubu la PTFE, pomwe mkuyu 1 ukuwonetsa ntchito zake m'magawo osiyanasiyana.

Mu magalimoto ofunsira, kuthekera kwa PTFE kupirira kutentha kopitilira 250 ° C kumapangitsa kukhala woyenera kutengera kutentha kwamadzimadzi.

M'mapulogalamu azachipatala,PTFE chubuikufunika kwambiri chifukwa chamafuta ake komanso kusagwira ntchito kwamankhwala.Ma catheters omwe amagwiritsa ntchito chubu la PTFE amatha kuyikidwa m'thupi la munthu popanda kuopa kuti angachite kapena kuvulala ndi ziwalo zilizonse zathupi.

Mu mankhwala - kuphatikizapo ma laboratories - PTFE ndi yabwino m'malo galasi chifukwa inertness ndi durability.

Pamagetsi amagetsi, zida zabwino kwambiri za dielectric za namwali PTFE zimapangitsa kuti ikhale yoyenera kutsekereza zingwe zamphamvu kwambiri.

APPLICATION PTFE

Mitundu ya PTFE chubu

Kutengera kugwiritsa ntchito, chubu la PTFE lagawidwa m'magulu atatu otakata - chilichonse chimatanthauzidwa ndi kukula kwa chubu ndi makulidwe a khoma (onani Gulu 2).

magulu a PTFE chubu

Ngakhale m'magulu, chubu la PTFE limadzibwereketsa kumitundu yosiyanasiyana, iliyonse imalola kugwiritsa ntchito kosiyana (onani Gulu 3):

PTFE chubu pamsika wa zida zamankhwala

Nthawi zambiri, chubu chaching'ono cha spaghetti chimagwiritsidwa ntchito pazachipatala.Kugwiritsiridwa ntchito kwa PTFE m'derali kumakhazikika pazinthu ziwiri zazikulu: lubricity ndi biocompatibility.Ma fluoropolymers amawonetsa mafuta abwino kwambiri poyerekeza ndi mapulasitiki ena.PTFE ndiye polima wonyezimira kwambiri yemwe alipo, wokhala ndi mikangano ya 0.1, yotsatiridwa ndi fluorinated ethylene propylene (FEP), yokhala ndi 0.2.Ma polima awiriwa akuyimira kuchuluka kwa machubu onse a fluoropolymer omwe amagwiritsidwa ntchito pazida zamankhwala.

Biocompatibility ya polima iliyonse yomwe imagwiritsidwa ntchito pazida zamankhwala ndizodetsa nkhawa.PTFE imapambana m'derali ndipo ili ndi mbiri yakale yogwiritsa ntchito mu vivo.Ma fluoropolymers achipatala ayenera kukwaniritsa zofunikira za USP Class VI ndi ISO 10993.N’zoona kuti kukonza ukhondo n’kofunikanso kwambiri.

Pazaka 18 zapitazi, Besteflon imayang'ana mosalekeza kupanga machubu a PTFE ndi payipi ya PTFE.Monga apainiya m'dera la kupanga fluoroplastics, timatsata ntchito zabwino kwambiri komanso zogulitsa pambuyo pogulitsa.Ngati mungafune kuyamba kusintha chubu la PTFE kuti mugwiritse ntchito mwapadera, chonde omasuka kulankhula nafe!
