PTFE, FEP ndi PFA ndi fluoroplastics odziwika bwino komanso odziwika bwino.Koma kodi, kwenikweni, kusiyana kwawo ndi chiyani?Dziwani chifukwa chake ma fluoropolymers ali zida zapadera, ndi fluoroplastic yomwe ili yoyenera kwambiri pakugwiritsa ntchito kwanu.
Zapadera za fluoroplastics
Ma fluoropolymers amasangalala ndi zinthu zingapo zapadera zomwe zimawapangitsa kukhala oyenera kugwiritsidwa ntchito pazachipatala, zamagalimoto, zamagetsi ndi zapakhomo, pakati pa ena.
Fluoroplastics ali ndi zinthu zotsatirazi:
1.Kutentha kwambiri kwa ntchito
2.Makhalidwe osakhala ndi ndodo
3.Low mkangano pamwamba
4.Kukana kwambiri kwa mankhwala ndi zosungunulira
5.Kukana kwambiri kwamagetsi
Ma fluoroplastic osiyanasiyana amasangalala ndi kusiyana kosawoneka bwino, kuphatikiza kutentha kosiyanasiyana kogwira ntchito, ndipo ndi oyenera kugwiritsa ntchito mosiyanasiyana.Ngati asankhidwa bwino, ma fluoropolymers amatha kupereka zabwino zamtengo wapatali komanso magwiridwe antchito.
Ubwino wa PTFE
PTFE, kapena Polytetrafluoroethylene, ndi agogo a fluoroplastics onse.Wodziwika ndi wasayansi Roy J. Plunkett mu 1938, PTFE ndi fluoropolymer yachilendo kwambiri ndipo imasonyeza ntchito yabwino kwambiri yokhudzana ndi kutentha, kukana mankhwala ndi zinthu zopanda ndodo.
Kuphatikiza pa kusangalala ndi mawonekedwe apadera a fluoroplastics, PTFE imadzisiyanitsa ndi izi:
1. Mtengo wabwino kwambiri: chiŵerengero cha ntchito
2. Kutentha kosalekeza kogwira ntchito kwa +260 ° C - Uku ndiye kutentha kwapamwamba kwambiri kwa fluoroplastic iliyonse
3.Kutsutsa pafupifupi mankhwala onse
4.Wopanda ndodo (ngakhale nalimata amatha kutsetsereka pa PTFE)
5.Translucent mtundu
Vuto lalikulu la PTFE ndikuti silisungunuka likatenthedwa ndipo ndizovuta kukonza.Njira zosagwirizana ndizomwe zimafunikira pakuwumba, kutulutsa ndi kuwotcherera fuloropolymer iyi.
Chifukwa cha katundu wake wapadera, PTFE ndi abwino kwa ntchito mu kutchinjiriza magetsi ndi chitetezo cha zigawo zikuluzikulu zamagetsi.
Ndife akatswiri opangaptfe pa, ngati muli ndi mafunso, mutha kulumikizana nafe!
Ubwino wa FEP
FEP, kapena Fluoroethylenepropylene, ndiye mtundu wosungunuka wa PTFE.FEP ili ndi katundu wofanana kwambiri ndi PTFE, koma imakhala ndi kutentha kwapakati pa +200 ° C.Komabe, FEP imatha kukonzedwa mosavuta ndipo imatha kuwotcherera mosavuta ndikuwumbidwanso kukhala mbiri zovuta.
Komanso kukhala ndi mawonekedwe apadera a fluoroplastics, FEP imasangalala ndi izi:
1. Kuwotcherera ndi kukonzanso kuthekera
2. Kutentha kogwira ntchito kwa -200 ° C mpaka +200 ° C - FEP imakhala yosinthika pa kutentha kwa cryogenic
3.Total kukana mankhwala ndi UV
4.Bio-yogwirizana
5. Choyera mtundu
Chifukwa cha maubwino awa, kutentha kwa FEP kumakhala ndi kutentha kocheperako ndipo kumatha kuphwanyidwa bwino ndi zinthu zomwe zimakhudzidwa ndi kutentha popanda kuwopa kuwononga.Zotsatira zake, FEP ndiyabwino kuyika zida zamagetsi ndi zida.
Ubwino wa PFA
PFA, kapena Perfluoralkoxy, ndi mtundu wa kutentha kwambiri wa FEP.PFA ili ndi katundu wofanana ndi FEP koma ingagwiritsidwe ntchito pa kutentha kwa ntchito mpaka +260 ° C pamene imakhala yosungunuka, chifukwa cha kusungunuka kwamphamvu kwambiri kuposa PTFE.
Kuphatikiza pa kusangalala ndi mawonekedwe apadera a fluoropolymers, PFA imadzisiyanitsa ndi izi:
Kutentha kosalekeza kogwira ntchito kwa +260 ° C - Uku ndiye kutentha kwapamwamba kwambiri kwa fluoroplastic iliyonse
1.Kuwotcherera ndi kukonzanso kuthekera
2.Good permeability kukana
3.Kukaniza mankhwala abwino kwambiri, ngakhale pa kutentha kwakukulu
4.Bio-yogwirizana
5.High chiyero sukulu zilipo
6.Choyera mtundu
Choyipa chachikulu cha PFA ndikuti ndichokwera mtengo kuposa PTFE ndi FEP.
PFA ndiyabwino pamapulogalamu omwe amafunikira kalasi yoyera kwambiri, kukana kwamphamvu kwamankhwala komanso kutentha kwakukulu kogwira ntchito.Fluoroplastic iyi imagwiritsidwa ntchito kwambiri m'machubu azachipatala, zosinthira kutentha, mabasiketi a semi-conductor, mapampu ndi zopangira, ndi ma valve liner.
Pano paBesteflonndife akatswiri popereka mayankho aluso a fluoropolymer pamapulogalamu anu aukadaulo.Dziwani zambiri za wathuFluoroplastic Products.
