Kusintha kwa Polytetrafluoroethylene (PTFE) - kuchoka pa chinthu chogwiritsidwa ntchito pamtengo wapatali kupita ku chinthu chofunikira kwambiri kwakhala pang'onopang'ono kwambiri.
Komabe, m'zaka makumi awiri zapitazi, kugwiritsa ntchito PTFE kwakhala kofunikira kwambiri, zomwe zapangitsa kuti ikhale yothandiza kwambiri m'mafakitale, ogula komanso azachipatala oposa 200. Ndipo ngakhale mapepala, ndodo, zokutira ndi zida zina ndizo zomwe zimakopa msika waukulu wa zinthu za PTFE, chubu cha PTFE ndi payipi ya PTFE tsopano zikuyamba kukhala malo ofunikira kwambiri okulirapo.
Kugwiritsa ntchito chubu cha PTFE
Kugwiritsa ntchitoChubu cha PTFEyafalikira m'njira zosiyanasiyana kuphatikizapo magalimoto, mankhwala, zamagetsi ndi zamankhwala. Gome 1 likuwonetsa makhalidwe ofunikira omwe amafotokoza kusinthasintha kwa chubu cha PTFE, pomwe Chithunzi 1 chikuwonetsa kugwiritsidwa ntchito kwake m'magawo osiyanasiyana.
Mu ntchito zamagalimoto, kuthekera kwa PTFE kupirira kutentha kopitilira 250°C kumapangitsa kuti ikhale yoyenera kusamutsa madzi otentha kwambiri.
Mu ntchito zachipatala,Chubu cha PTFEikufunika kwambiri chifukwa cha mafuta ake komanso kusagwira ntchito kwa mankhwala. Ma catheter omwe amagwiritsa ntchito chubu cha PTFE amatha kulowetsedwa m'thupi la munthu popanda mantha kuti ziwalo zina za thupi zingakhudzidwe kapena kuvulala.
Mu ntchito za mankhwala - kuphatikizapo ma laboratories - PTFE ndi malo abwino kwambiri m'malo mwa galasi chifukwa cha kusagwira kwake ntchito komanso kulimba kwake.
Mu ntchito zamagetsi, mphamvu zabwino kwambiri za dielectric za virgin PTFE zimapangitsa kuti zikhale zoyenera kwambiri poteteza zingwe zamagetsi amphamvu.
Mitundu ya chubu cha PTFE
Kutengera ndi momwe ntchito ikuyendera, chubu cha PTFE chimagawidwa m'magulu atatu akuluakulu - chilichonse chimafotokozedwa ndi kukula kwa chubu ndi makulidwe a khoma (onani Gome 2).
Ngakhale mkati mwa magulu, chubu cha PTFE chimapereka mitundu yosiyanasiyana, iliyonse imalola kugwiritsa ntchito kosiyana (onani Gome 3):
Chubu cha PTFE pamsika wa zida zamankhwala
Kawirikawiri, chubu chaching'ono cha spaghetti chimagwiritsidwa ntchito pa ntchito zachipatala. Kugwiritsa ntchito PTFE m'derali kumadalira pa zinthu ziwiri zofunika: kukhuthala ndi kuyanjana kwa zinthu. Ma fluoropolymers amasonyeza kukhuthala kwabwino kwambiri poyerekeza ndi mapulasitiki ena. PTFE ndiye polima wokhuthala kwambiri womwe ulipo, wokhala ndi coefficient of friction ya 0.1, kutsatiridwa ndi fluorinated ethylene propylene (FEP), yokhala ndi 0.2. Ma polima awiriwa akuyimira chubu chachikulu cha fluoropolymer chomwe chimagwiritsidwa ntchito muzipangizo zachipatala.
Kugwirizana kwa polima iliyonse yomwe imagwiritsidwa ntchito mu chipangizo chachipatala ndi nkhani yodziwikiratu. PTFE imachita bwino kwambiri pankhaniyi ndipo yakhala ikugwiritsidwa ntchito kwa nthawi yayitali m'thupi. Ma fluoropolymers a digiri ya zamankhwala ayenera kukwaniritsa zofunikira pakuyesa kwa USP Class VI ndi ISO 10993. Zachidziwikire, ukhondo wokonza zinthu ndi chinthu chofunikira kwambiri.
Kwa zaka 18 zapitazi, Besteflon yakhala ikuyang'ana kwambiri pakupanga ma PTFE Tubes ndi PTFE hose. Monga oyambitsa kupanga ma fluoroplastics, timayesetsa kupeza ntchito yabwino kwambiri komanso yogulitsa pambuyo pogulitsa. Ngati mukufuna kuyamba kusintha chubu cha PTFE kuti chigwirizane ndi ntchito yanu yapadera, chonde musazengereze kulumikizana nafe!
