PTFE, FEP thiab PFA yog cov paub zoo tshaj plaws thiab muaj cov fluoroplastics.Tab sis dab tsi, raws nraim, lawv qhov txawv?Tshawb nrhiav vim li cas fluoropolymer yog cov khoom siv tshwj xeeb, thiab cov fluoroplastic twg yog qhov zoo tshaj plaws rau koj daim ntawv thov.
Cov khoom tshwj xeeb ntawm fluoroplastics
Fluoropolymers nyiam ntau yam khoom tshwj xeeb uas ua rau lawv tsim nyog siv rau hauv kev kho mob, tsheb, hluav taws xob thiab kev siv hauv tsev, thiab lwm yam.
Fluoroplastics muaj cov khoom nram qab no:
1. Ua haujlwm kub heev
2. Cov yam ntxwv tsis yog nplaum
3. Tsawg kev sib txhuam nto
4.High tsis kam rau tshuaj thiab cov kuab tshuaj
5.High hluav taws xob tsis kam
Cov fluoroplastics sib txawv nyiam qhov sib txawv me me, nrog rau qhov sib txawv ntawm qhov kub thiab txias ua haujlwm, thiab haum rau kev siv sib txawv.Yog tias xaiv kom raug, fluoropolymers tuaj yeem xa cov nqi zoo thiab cov txiaj ntsig kev ua haujlwm.
Cov txiaj ntsig ntawm PTFE
PTFE, los yog Polytetrafluoroethylene, yog yawm txiv ntawm tag nrho cov fluoroplastics.Tshawb nrhiav los ntawm tus kws tshawb fawb Roy J. Plunkett hauv xyoo 1938, PTFE yog cov fluoropolymer txawv txawv tshaj plaws thiab nthuav tawm qhov kev ua tau zoo tshaj plaws ntawm qhov kub, tshuaj tiv thaiv thiab cov khoom tsis-stick.
Ntxiv nrog rau kev txaus siab rau cov khoom tshwj xeeb ntawm fluoroplastics, PTFE txawv nws tus kheej los ntawm kev muaj cov txiaj ntsig hauv qab no:
1.Zoo tshaj tus nqi: kev ua tau zoo piv
2.Nruam ua haujlwm kub ntawm +260 ° C - Qhov no yog qhov ua haujlwm siab tshaj plaws rau txhua yam fluoroplastic
3.Resistance yuav luag txhua yam tshuaj
4.Highly non-stick (txawm tias gecko yuav plam ntawm PTFE)
5.Cov xim zoo nkauj
Lub ntsiab tsis zoo ntawm PTFE yog tias nws tsis tau yaj thaum rhuab thiab yog li nyuaj rau txheej txheem.Cov txheej txheem tsis zoo heev yog xav tau los pwm, extrude thiab vuam no fluoropolymer.
Vim nws cov khoom tshwj xeeb, PTFE yog qhov zoo tagnrho rau kev siv hluav taws xob rwb thaiv tsev thiab kev tiv thaiv hluav taws xob.

Cov txiaj ntsig ntawm FEP
FEP, los yog Fluoroethylenepropylene, yog cov yaj-ua tiav ntawm PTFE.FEP muaj cov khoom zoo sib xws rau PTFE, tab sis muaj qhov ua haujlwm qis tshaj plaws ntawm +200 ° C.Txawm li cas los xij, FEP tuaj yeem ua tau yooj yim dua thiab tuaj yeem yooj yim welded thiab rov moulded rau hauv cov ntaub ntawv nyuaj.
Ntxiv nrog rau muaj cov khoom tshwj xeeb ntawm fluoroplastics, FEP txaus siab rau cov txiaj ntsig no:
1. Vuam thiab rov moulding muaj peev xwm
2.Kev ua haujlwm kub ntawm -200 ° C rau + 200 ° C - FEP tseem hloov tau ntawm qhov kub thiab txias
3.Tag nrho cov tshuaj tiv thaiv thiab UV
4.Bio-compatible
5. Cov xim ntshiab
Ua tsaug rau cov txiaj ntsig no, FEP tshav kub ntsws muaj qhov qis qis thiab tuaj yeem ua rau muaj kev nyab xeeb ntawm cov ntaub ntawv kub thiab tsis muaj kev ntshai ntawm kev puas tsuaj.Yog li ntawd, FEP yog qhov zoo tshaj plaws rau encapsulating rhiab hluav taws xob Cheebtsam thiab ntsuas.
Cov txiaj ntsig ntawm PFA
PFA, lossis Perfluoralkoxy, yog qhov kub thiab txias ntawm FEP.PFA muaj cov khoom zoo sib xws rau FEP tab sis tuaj yeem siv tau ntawm kev ua haujlwm kub txog +260 ° C thaum tseem yaj-ua tiav, ua tsaug rau qhov qis qis dua li PTFE.
Ntxiv nrog rau kev txaus siab rau cov khoom tshwj xeeb ntawm fluoropolymers, PFA txawv nws tus kheej los ntawm kev muaj cov txiaj ntsig hauv qab no:
Kev ua haujlwm tsis tu ncua ntawm + 260 ° C - Qhov no yog qhov ua haujlwm siab tshaj plaws rau txhua yam fluoroplastic
1.Vuam thiab rov moulding muaj peev xwm
2.Zoo permeability kuj
3.Excellent tshuaj tiv thaiv, txawm nyob rau hauv siab kub
4.Bio-compatible
5.High purity qib muaj
6. Cov xim ntshiab
Lub ntsiab tsis zoo ntawm PFA yog tias nws kim dua PTFE thiab FEP.
PFA yog qhov zoo tagnrho rau cov ntawv thov uas xav tau qib purity siab dua, tshuaj lom neeg ua haujlwm zoo thiab ua haujlwm kub.Qhov no fluoroplastic yog dav siv nyob rau hauv kev kho mob tubing, tshav kub exchangers, semi-conductor baskets, twj thiab fittings, thiab valve liners.
