Intshayelelo ngo I-Teflon High-Temperature Fabric Manufacturer kuMahluko phakathi kwe-PTFE Emulsions eveliswe ziiNkqubo zePolymerization ezahlukeneyo (Ukumiswa kwePolymerization kunye ne-Dispersion Polymerization)
I. Ukucaciswa kwangaphambili kweeNgcaciso
Kwi-industrial practice, i-polymerization yokumiswa ayikwazi ukuvelisa ngokuthe ngqo i-emulsion ye-PTFE. I-emulsion ye-PTFE yokwenene (i-dispersion) iveliswa kuphela yi-dispersion polymerization (eyi-emulsion polymerization). I-Jiangsu Teflon High-Teflon Fabric Fabric Manufacturer iphawula ukuba ifumaneka ngokurhweba 'indlela yokumiswa-ye-PTFE emulsion' ngokwenene kukunqunyanyiswa kwamanzi okwenziwa ngomatshini wokuchithachitha i-suspension-polymerized resin micropowders. Ezi zimbini zahluke ngokusisiseko, ukusuka kwi-particle nature ukuya kusetyenziso lokugqibela.
II. Ukusasazwa kwePolymerization: Primary PTFE Emulsion
1. I-Particle Morphology kunye nokuzinza
Iingqungquthela zi-spherical ngokugqibeleleyo, zenziwe yi-agglomeration ye-primary particles (0.05-0.5 μm) kwiincinci zesibini ezinobungakanani be-0.1-0.3 μm kunye nokusabalalisa ubungakanani obuncinci kakhulu. Uzinzo lubonelelwa nge-perfluorinated surfactants (iindlela ezizezinye zePFOA) ezongeziweyo ngexesha lepolymerization. Inkqubo ye-colloidal inokuhlala izinzile ngaphandle kwe-stratification iminyaka kwaye ibonisa ukuchasana okulungileyo kwi-chear mechanical.
Ubunzima be-molecular buphezulu kakhulu (ukuya kwizigidi ezininzi), kunye ne-crystallinity edlula i-94% kunye nomthamo onamandla kakhulu we-fibrillation. Emva kokugquma, ukushisa okuphezulu kwe-sintering malunga ne-380 ° C kuyafuneka, ngexesha apho amaqhekeza adibanisa kwifilimu eqhubekayo, exineneyo, enzima kunye neempawu ezichasene ne-corrosion kunye ne-non-stick.
3. ULungiselelo oluQhelekileyo kunye nezicelo
Ukucutshungulwa kunqunyelwe kwi-extrusion yokuncamathelisa, ukufakwa, okanye ukugquma kulandelwa yi-sintering. Usetyenziso oluqhelekileyo lubandakanya ii-cookware ezingabambekiyo, ukufakwa kwe-fiberglass ye-architectural membranes, i-microporous ePTFE membranes (ephefumulayo kunye nengenamanzi), kunye neefilimu ze-capacitor eziphezulu.
III. IMicropowder yokuNxinywa kwePolymerization: Ukunqunyanyiswa okumanzi (Kudla ngokubhalwa ngokungafanelekanga njengeEmulsion)
1. I-Particle Morphology kunye nokuzinza
Njengoko kuphawulwe nguJiangsu Teflon uMenzi weFabric Fabric High-Temperature: Iingqungquthela ziveliswa ngokusila kunye nokutyumza iipellets ze-polymerized suspension-polymerized, okubangelwa imilo ye-polyhedral engaqhelekanga kunye nobukhulu be-particle ukusuka kwi-2 ukuya kwi-20 μm kunye nokusabalalisa ubungakanani obubanzi. Inkqubo ayizinzanga ngokwe-thermodynamically kwaye ithandeka kakhulu kwintlenga kunye ne-stratification. Iifakthi eziqhelekileyo kunye nezinto ezityebisayo ezifana ne-xanthan gum kunye ne-cellulose ethers kufuneka zongezwe kwi-retard sedimentation, kwaye ukuvuselela okucokisekileyo kuyafuneka phambi kokusetyenziswa.
Ubunzima bemolekyuli bunokulungelelaniswa kuluhlu oluphantsi kakhulu (amashumi amawaka ukuya kumakhulu amawaka), kunye ne-brittleness enkulu kunye ne-fibrillation ebuthathaka kakhulu. Emva kokugquma, ukumisa kuphela okuphantsi okanye okuphantsi kweqondo lokushisa kuyafuneka ukwenza umaleko owomileyo wokuthambisa; ayinakudlalwa kwifilimu.
3. ULungiselelo oluQhelekileyo kunye nezicelo
Inokuthi ifakwe ngokuthe ngqo kwiifomyula okanye isetyenziswe ngokutyabeka kunye nomoya owomileyo. Izicelo zibandakanya izongezo ze-lubricant kwimizi-mveliso, irabha kunye nezixhobo zokukhulula ukungunda kweplastiki, i-anti-wear kunye ne-slip agents kwii-inki kunye neengubo, kunye nokugqitywa kwamanzi kwimpahla yangaphandle.
