Molao-motheo o Sebetsang le Tlhahlobo ea Tšebeliso ea Liphaephe tsa PFA le Lithupa tsa Welding

Lefapheng la kajeno la indasteri, liphaephe tsa PFA (perfluoroalkoxy resin) le lithupa tse tsamaisanang le welding li fetohile lisebelisoa tsa bohlokoa indastering ea lik'hemik'hale, tsa semiconductor, tsa meriana le tse ling ka lebaka la khanyetso ea tsona e ntle ea lik'hemik'hale, ho hanyetsa mocheso o phahameng le khohlano e tlase. Sengoliloeng sena se tla sekaseka ka botebo molao-motheo oa ts'ebetso le melemo ea ts'ebeliso ea liphaephe tsa PFA le lithupa tsa welding.

Molao-motheo oa ho sebetsa le Litšobotsi tsa Liphaephe tsa PFA

Liphaephe tsa PFA ke-liphaephe tse sebetsang hantle tsa fluoroplastic tse nang le sebopeho sa molek'hule se ts'oanang le PTFE (polytetrafluoroethylene), empa se na le maemo a holimo le ts'ebetso ea ts'ebetso. Litšobotsi tsa mantlha tsa liphaephe tsa PFA li kenyelletsa:

Khanyetso ea corrosion ea lik'hemik'hale: PFA e na le khanyetso e matla ho hoo e ka bang li-acid tsohle tse matla, li-alkali tse matla le li-solvents tsa organic, 'me e loketse ho tsamaisa mecha ea litaba e senyang.

Ho hanyetsa mocheso o phahameng: PFA e ka sebelisoa nako e telele ho mocheso oa -200℃ho +260℃, 'me nako e khutšoanyane-ea ho hanyetsa mocheso o ka fihla ho 300 degrees , ho finyella litlhoko tsa mekhoa ea mocheso o phahameng.

Khokahano e tlase ea khokahanyo: Lerako le ka hare la lipeipi tsa PFA le boreleli, 'me khohlo e tlase haholo, e ka fokotsang khaello ea mokelikeli 'me e loketse lipalangoang tse phahameng- tsa metsi a hloekileng.
Tšebeliso e ntle ea motlakase: PFA e na le matla a phahameng haholo a dielectric le thepa ea insulation, 'me e loketse indasteri ea elektroniki le ea semiconductor.
Mokhoa oa ho sebetsa le ts'ebetso ea welding ea lithupa tsa welding tsa PFA

Lithupa tsa welding tsa PFA ke lisebelisoa tse khethehileng tse sebelisetsoang ho hokahanya liphaephe kapa likarolo tsa PFA. Molao-motheo oa bona oa tjheseletsa o thehiloe ho thekenoloji ea khokahano ea hot melt. Mekhoa e tloaelehileng ea welding e kenyelletsa:

Ho cheseletsa moea o chesang​​: The welding rod ea PFA le phala li futhumatsoa hore e be boemong ba ho qhibiliha ka nako e le ’ngoe ke moea o chesang{0}} o phahameng, ebe joale ho kenngoa khatello ea ho li kopanya, ebe khokahanyo e tiileng e thehoa ka mor’a hore ho pholile.
Extrusion welding: Kamora hore molamu oa tjheseletso oa PFA o qhibilihe ke sethunya se khethehileng sa tjheseletsa, se hatelloa ka ho lekana ho karolo e tla kolobisoa ho etsa weld ea junifomo.

Senotlolo sa ho tjheseletsa ha PFA ke ho laola mocheso le lebelo la welding ho netefatsa ho qhibiliha ho lekaneng ntle le li-bubble kapa litšila, ka tsela eo ho netefatsa matla a ho cheselletsa le ho tšoarella.

Libaka tsa kopo le litebello tsa 'maraka

Liphaephe tsa PFA le lithupa tsa welding li sebelisoa haholo liindastering tse kang lik'hemik'hale, li-semiconductors, meriana le ts'ebetso ea lijo, haholo-holo maemong ao ho oona ho hlokahalang bohloeki bo phahameng, ho hanyetsa kutu le ho hanyetsa mocheso o phahameng. Ka tlhokahalo e ntseng e hola ea-lisebelisoa tse sebetsang hantle indastering ea lefats'e, menyetla ea 'maraka ea liphaephe tsa PFA le li-welding rod e pharaletse.

Nakong e tlang, ka tsoelo-pele ea mahlale a lintho tse bonahalang, ts'ebetso ea liphaephe tsa PFA le lithupa tsa welding li tla ntlafatsoa le ho feta, ho fana ka tharollo e tšepahalang haholoanyane bakeng sa liindasteri tse fapaneng.
