Eli nqaku lichaza indlela yokuthintela ungcoliseko kunye nomonakalo wokusebenza kwicala elingabambeleliyo le-PTFE iteyiphu yobushushu obuphezulu ngexesha lenkqubo yokwambathisa. Izicwangciso eziphambili zibandakanya ukulawulwa komthombo (unyango oluchanekileyo lomhlaba), ukuhlukaniswa ngokomzimba (iifilimu ezikhuselayo, i-roller non-stick rollers, ukomiswa kwendawo), kunye nokulawulwa kwenkqubo esulungekileyo.

Eli nqaku licacisa ukuba kutheni ilaphu le-fiberglass engena-alkali iyeyona ikhethwayo kwilaphu le-PTFE lobushushu obuphezulu. Ibandakanya ukuhlangana kweekhemikhali kusetyenziswa i-silane coupling agents kunye neempawu eziphambili zomzimba ezifana nokuzinza kwe-thermal, uzinzo lwe-dimensional, kunye nokumelana nomhlwa-ukuqinisekisa ukusebenza okuhlala ixesha elide kwiindawo ezinzima.

Ukufakela iteyiphu yobushushu obuphezulu be-PTFE ngokuqinileyo kwimiphezulu egobileyo nengaqhelekanga ngaphandle kwamaqamu kunye ne-edge warping, inkqubo yokusebenza esemgangathweni ibalulekile, kubandakanywa ukunyangwa ngokucokisekileyo kwe-substrate, izakhono zobuchule bokusebenza kunye namanyathelo ancedisayo afanelekileyo. Phakathi kwabo, i-substrate pretreatment lelona nyathelo libaluleke kakhulu, elimisela malunga ne-70% yesiphumo sokuncamathela sokugqibela.

Ngokuchasene nemvelaphi yemithetho engqongqo yokusingqongileyo, i-PFOS/PFOA-free PTFE emulsion yimveliso ephuculweyo ephuhliswe endaweni yeenkqubo ze-PFOA eziqulathe iipolymerization. Igcina iimpawu ezingundoqo ze-PTFE ngelixa iphucula kakhulu ubuhlobo bendalo kunye nokhuseleko lwezempilo.

I-coefficient yokwandisa i-thermal ye-PTFE yelaphu lobushushu obuphezulu ayiloxabiso elimiselweyo. Ihlala iphantsi kwinqanaba lokushisa ukuya kwi-100 ° C (malunga ne-0.5 × 10⁻⁵ / ° C), kodwa iphakama ngokukhawuleza phantsi kweemeko eziphezulu zokushisa.

Njengomvelisi oqeqeshiweyo we-PTFE ilaphu lobushushu obuphezulu, i-Jiangsu Aokai New Materials yabelana ngobuchule bokukrolwa okungundoqo. Ukunqanda i-burrs, i-delamination kunye nokutenxa komda ngexesha lokunqunyulwa, kubalulekile ukulawula ngokucwangcisiweyo izinto ezine eziphambili: izixhobo zokusika, izixhobo, imathiriyeli ekrwada.

Njengomvelisi wokuqala we-PTFE iiteyiphu zobushushu obuphezulu, i-Jiangsu Aokai New Materials apha ichaza iimpembelelo zeendlela zokupholisa kunye namazinga okupholisa ekusebenzeni kwe-PTFE ephilisiwe iteyiphu zobushushu obuphezulu.I. Undoqo we-PTFE Crystallization Iimpawu kunye noLawulo lweRayithi lokuPholisaI-PTFE su

Njengomvelisi oqeqeshiweyo we-PTFE ilaphu lobushushu obuphezulu, i-Jiangsu Aokai New Materials ithatha ukuba ufunde ngakumbi. Kwiimeko ezininzi, iglu enyangisiweyo kunye nentlaka inokuxolwa ngokupheleleyo kwilaphu lobushushu obuphezulu le-PTFE kwaye phantse akukho ntsalela iseleyo. Nangona kunjalo, esi siphumo asiyiyo ngokupheleleyo. Eyona nto

Njengomvelisi oqeqeshiweyo wamalaphu obushushu obuphezulu be-PTFE, i-Jiangsu Aokai New Materials ikunika ulwazi lobungcali. Eyona njongo yonyango lomphezulu we-fiberglass kukwakha ibhulorho yemolekyuli phakathi kwe-inorganic fiberglass kunye ne-organic PTFE, ukuze basombulule ngokusisiseko inc yabo.

Njengomvelisi oqeqeshiweyo wamalaphu obushushu obuphezulu be-PTFE, iJiangsu Aokai New Materials yabelana nawe ngolwazi olufanelekileyo lweshishini. I-Edge warping kunye nokuwa kwe-PTFE iiteyipu zokushisa eziphezulu azifane zibangelwa yinto enye, kodwa zibangelwa kwimiphumo edibeneyo yokukhetha okungafanelekanga kweteyipu,
