I-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe wendwangu ye-PTFE eshisa kakhulu, inikeza ukuhlaziywa okujulile. Ukwelashwa kwe-Matt sanding kuletha izinguquko eziyisisekelo esakhiweni esingaphezulu sendwangu ye-PTFE enezinga lokushisa eliphezulu. Iguqula indawo yasekuqaleni engenzi lutho, ebushelelezi ibe indawo yokusebenza ebophekayo, emanzisa kalula ukusuka ezinhlangothini ezintathu: i-morphology ebonakalayo, ubuqotho bokumboza kanye nesimo samakhemikhali angaphezulu.
1. I-Microscopic Morphology: Kusuka Kubuso Esibushelelezi Esibushelelezi ukuya Ekubunjweni Kwemibhobho Emabhodlo
Ubuso obungaphathwanga bendwangu ye-PTFE eshisa kakhulu bushelelezi ngaphansi kwezibonakhulu, kwakhiwa ifilimu eqhubekayo ye-polytetrafluoroethylene encibilikayo. Ukwelashwa kwesihlabathi kushintsha kakhulu i-micro-morphology yayo:
· Ukwanda okubukhali kokuqina kwendawo: Ukusahlabathi ngemishini (amabhande abrasive, amabhulashi ezintambo zensimbi) noma ukuqhunyiswa kwesihlabathi (i-corundum, i-alumina emhlophe ehlanganisiwe) kusikeka futhi kuthinte indawo engaphezulu, kudweba imigodi emincane engabaleki, imigodi neziqongo. Izinkomba zokushelela okuyinhloko u-Ra (ukuchezuka kwencazelo yezibalo zephrofayela ehloliwe) kanye ne-Rz (ubude obungamaphoyinti ayishumi okungahambi kahle) ziphindaphindeka kakhulu.
· Ukwakhiwa kwesakhiwo sokubambelela ngomshini: Lezi zindawo ezincane azizona imihuzuko elula, kodwa izakhiwo ezixhumene ze-3D. Lona umnyombo womphumela wokunamathisela: izinto ezinamathelayo zingena kulezi zikhala futhi zelaphe ukuze zenze ukuhlobana okungokomzimba ukuze kuhlanganiswe noma kuhlanganiswe okulandelayo.
· Ukufana kwendawo okushintshile: Ukusahlabathi ngendlela efanele kuletha isiphetho esine-matte. Ukulawulwa kwenqubo okungalungile kubangela izindawo ezinesihlabathi esingaphezu kwesihlabathi (uqweqwe oluncishiswe kakhulu) kanye namapheshana abushelelezi angafakwanga esihlabathini, okuholela ekuhlukeni kwe-heterogeneous morphology.
2. Ubuqotho Bokumboza: Kusukela Kufilimu Engaguquki Eqhubekayo ukuya Kowonakele, I-substrate Eveziwe
Lena ingozi ebaluleke kakhulu edinga ukulawulwa kwenqubo okuqinile, enquma ngokuqondile ukusebenza kwesevisi okuyisisekelo komkhiqizo:
· Ukuncishiswa kongqimba lwe-PTFE: Ukufakwa kwesihlabathi kuyinqubo yokususwa kwezinto ezibonakalayo. Indwangu ye-PTFE yendwangu enezinga eliphezulu lokushisa ngokuvamile isukela emashumini kuya kumakhulu ama-microns awugqinsi. Ukwenza isihlabathi ngokweqile kunciphisa kakhulu ukujiya kokunamathela, kwehlisa amandla e-dielectric kanye nempilo yesevisi yokumelana nokugqwala kwamakhemikhali.
· Ingozi ye-fiberglass substrate eveziwe (isici esibi kakhulu sesakhiwo): Uma ukujula kokugaya kudlula ukujiya kwenamathela ye-PTFE, indwangu engaphansi ye-fiberglass izohuzuka, kuqalise uchungechunge lokuhluleka:
1. Ukulahleka kwempahla enganamathele: Imicu yengilazi eveziwe inamathela kalula ezintweni;
2. Ukungena komswakama namakhemikhali: Umhwamuko wamanzi namakhemikhali kungena endwangu nge-capillary action of glass fibers, okuholela ekulimazeni nasekuwohlokeni kokusebenza ngokushesha;
3. Amandla okusebenza ancishisiwe: Ukuhushulwa kwemicu yengilazi kubangela ukwehla okubukhali kwamandla aqinile ayo yonke indwangu.
· Ukukhiqizwa kwama-microcracks kanye nemfucumfucu enqwabelene: Ukusika okulimazayo ku-PTFE kuhlanganisa ukuphuka okuphukayo kanye nokuklebhuka kwe-ductile, kwakha ama-microcracks nama-burrs emaphethelweni emisele nangaphansi. Ngaleso sikhathi, ama-chips e-PTFE ahlutshiwe angase aphinde adiphozi ngokukhululekile phezulu, akhe izakhiwo ezixegayo ezifana nesiqhingi ezifaka engozini ukwethembeka kokunamathela noma ukubopha okulandelayo.
3. Isimo Sekhemikhali Yokuphezulu: Kusuka ku-Ultra-Inert kuya Kokucushiwe
Nakuba ukwenza isihlabathi ngokuyinhloko kuwukwelapha ngokomzimba, kuphinde kubangele izinguquko ezimpahleni zamakhemikhali ezingaphezulu:
· Amandla angaphezulu aphakeme: I-PTFE ehlanzekile inamandla angaphezulu aphansi kakhulu (18–20 mN/m), ene-engeli yokuthinta amanzi ngaphezu kuka-108°. Ngemva kokusetshenzwa kwesihlabathi, izindawo ezisanda kwakhiwa ezimahhadlahhadla kanye namaketango emolekyuli aphukile aveza okwesikhashana amasayithi asebenzayo anamandla, aphakamisa amandla angaphezulu kuka-40 mN/m. Amaconsi amanzi asakazeka futhi amanzise indawo engaphezulu, ebonisa i-hydrophilicity yesikhashana, efiphala kancane kancane ngokuhamba kwesikhathi.
· Ukwethulwa kwesikhashana kwamaqembu asebenza endaweni epholile: Ukugaya okunamandla amakhulu kubangela ukusabela phakathi kwamaketanga emolekyuli e-PTFE aphukile nomoya-mpilo/umswakama osemoyeni, okukhiqiza ngokushesha amaqembu asebenza endaweni epholile njenge-carbonyl (C=O) ne-hydroxyl (-OH). Lawa maqembu anika amandla ukuhlangana kwamakhemikhali ukuze kuthuthukiswe ukuguqulwa kwamakhemikhali noma i-adhesive lamination.
Isifinyezo Semithelela Ephelele
Ngamafuphi, ukwelashwa kwesihlabathi okufanelekile kudala ukwakheka okufanayo, okumahhadla, okwenziwe kusebenze i-micro-nano endwangu ye-PTFE ngaphandle kokulimaza i-fiberglass substrate engaphansi.
· Uguquko oluhle: Idala ukuthungwa okuhlanganayo kokusebenza ukuze kuxazululwe inkinga ye-PTFE yemvelo empofu yokunamathela.
· Izithiyo ezimbi: Idela ukusebenza kwasekuqaleni okungagxili, ukushelela kwendawo kanye nokungafihli lutho, okunezingozi ezingapheli zokulimala kwe-substrate kanye nempilo yesevisi efinyeziwe.
Ngakho-ke, umnyombo wale nqubo usekulawuleni okunembile kokujula kokususwa kwempahla — kuphela ungqimba olungaphezulu lwe-PTFE oluhunyushiwe, ngaphandle kokuthinta uhlaka lwamathambo e-fiberglass. Indwangu ephathwayo ivamise ukuthunyelwa ezinqubweni zokumboza noma zokubopha ngokushesha ukuze isebenzise ngokugcwele isimo sayo esiphezulu esisebenza ngokugcwele.
