Ukufakwa kwe-PTFE akugcini nje ngendwangu ye-fiberglass. Lesi sihloko sethula ama-substrates angu-7 ahlukile - i-aramid, i-carbon fibre, i-PBI, insimbi enezimbotshana, i-graphite, i-asbestos (ikhishiwe), kanye nezigcwalisi ze-ceramic - nezici zazo zenqubo, izinzuzo, imikhawulo, nezinhlelo zokusebenza ezibalulekile.

Indwangu yokushisa ephezulu ye-PTFE ephefumula kakhulu ihlanganisa izakhiwo ezinganamatheli, ukuzinza okushisayo, nokungena komoya. Lesi sihloko sihlola ukusetshenziswa kwayo okubalulekile ekomisweni kwendwangu, ukucubungula ukudla, ukukhiqiza okuyinhlanganisela, izinto zikagesi, ukuthutha umoya, ukuvikelwa kwemvelo, nezinto zokwakha.

Lesi sihloko sichaza indlela yokuvimbela ukungcola nokusebenza kokulimala ohlangothini olunganamatheli lwe-PTFE itheyiphu yokushisa ephezulu ngesikhathi senqubo yokumboza. Amasu abalulekile ahlanganisa ukulawulwa komthombo (ukwelashwa okuqondile kwendawo), ukuzihlukanisa ngokomzimba (amafilimu avikelayo, amarola angagxili, ukomiswa kwendawo), kanye nokuphathwa kwenqubo ecolisisiwe.

Lesi sihloko sichaza ukuthi kungani indwangu ye-fiberglass engena-alkali iyisisekelo esincanyelwayo sendwangu ye-PTFE enezinga lokushisa eliphezulu. Ihlanganisa ukubopha kwamakhemikhali ngama-ejenti ahlanganisayo we-silane kanye nezakhiwo ezibalulekile zomzimba njengokuzinza kwe-thermal, ukuzinza kwe-dimensional, nokumelana nokugqwala - iqinisekisa ukusebenza okuhlala isikhathi eside ezindaweni ezinokhahlo.

Ukuze usebenzise itheyiphu yokushisa ephezulu ye-PTFE ngokuqinile ezindaweni ezigobile nezingajwayelekile ngaphandle kwamabhamuza nokuguquguquka konqenqema, inqubo yokusebenza esezingeni ibalulekile, okuhlanganisa nokwelashwa kwe-substrate okuphelele, amakhono okusebenza ochwepheshe kanye nezinyathelo ezifanele zokusiza. Phakathi kwazo, ukwelashwa kwe-substrate kuyisinyathelo esibucayi kakhulu, esinquma cishe u-70% womphumela wokugcina wokunamathela.

Ngokumelene nokwasemuva kwemithetho eqinile yezemvelo, i-emulsion ye-PFOS/PFOA-free PTFE ingumkhiqizo othuthukisiwe othuthukisiwe ukuze ungene esikhundleni sezinqubo zendabuko ze-PFOA eziqukethe i-polymerization. Igcina izici eziyinhloko ze-PTFE kuyilapho ithuthukisa kakhulu ubungane bemvelo nokuphepha kwezempilo.

I-coefficient yokwandisa okushisayo yendwangu ye-PTFE yokushisa okuphezulu ayilona ivelu egxilile. Ihlala iphansi uma kuqhathaniswa nezinga lokushisa lasekamelweni ukuya ku-100°C (cishe u-0.5×10⁻⁵/°C), nokho ikhuphuka kakhulu ngaphansi kwezimo zokushisa eziphezulu.

Njengomkhiqizi ochwepheshe we-PTFE indwangu yokushisa okuphezulu, i-Jiangsu Aokai New Materials yabelana ngamasu okusika okuyisisekelo. Ukuze ugweme ama-burrs, i-delamination kanye nokuchezuka kobukhulu ngesikhathi sokusika, kubalulekile ukulawula ngokuhlelekile izakhi ezine ezibalulekile: amathuluzi okusika, okokusebenza, izinto zokusetshenziswa

Njengomkhiqizi wangempela wamakhasethi we-PTFE wamakhasethi okushisa aphezulu, i-Jiangsu Aokai New Materials ngalokhu ichaza imithelela yezindlela zokupholisa namazinga okupholisa ekusebenzeni kwamakhasethi e-PTFE apholile.I. Umongo Wezici ze-PTFE Crystallization kanye Nomthetho Wezinga LokupholisaI-PTFE su

Njengomkhiqizi ochwepheshe wendwangu ye-PTFE eshisa kakhulu, i-Jiangsu Aokai New Materials ikuthatha ukuze ufunde kabanzi. Ezimweni eziningi, iglue eselashiwe kanye ne-resin kungacwecwa ngokuphelele engutsheni yezinga lokushisa eliphezulu ye-PTFE cishe kungabikho nsali esele. Nokho, lo mphumela awuphelele. Okwangempela
