Jiangsu Aokai New Materials, ƙwararrun masana'anta na PTFE babban zane mai zafi, yana ba da bincike mai zurfi. Matt sanding jiyya kawo muhimman canje-canje ga surface tsarin PTFE high-zazzabi zane. Yana jujjuya asalin ultra-inert, ultra-smooth surface zuwa wani bondable, sauƙi wettable surface aiki daga girma uku: jiki ilimin halittar jiki, shafi mutunci da saman sinadarai yanayi.
Wurin da ba a kula da shi ba na PTFE babban zane mai zafin jiki yana da santsi a ƙarƙashin microscopes, wanda aka kafa ta ci gaba da fim na polytetrafluoroethylene narke-sintered. Maganin yashi yana canza micro-morphology sosai:
Ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan yanayin ƙasa: Yashi na injina (bels na ƙarfe, gogayen waya na ƙarfe) ko fashewar yashi (corundum, farin alumina) yana yanke da tasiri a saman, sassaƙa ƙananan ƙananan ramuka, ramuka da kololuwa. Ma'anoni roughness masu mahimmanci Ra (ma'anar lissafin lissafi na bayanin martaba da aka tantance) da Rz (tsawon maki goma na rashin bin ka'ida) suna ninka sosai.

Ƙirƙirar microcracks da tarkace masu tarawa: Yanke abrasive akan PTFE yana haɗakar da karaya da tsagewar ductile, ƙirƙirar microcracks da burrs tare da gefuna da gindi. A halin yanzu, kwakwalwan kwamfuta na PTFE da aka cire na iya sake yin ajiya a hankali a saman, suna samar da sifofi masu kama da tsibiri waɗanda ke yin illa ga amincin shafi ko haɗin gwiwa na gaba.
3. Surface Chemical State: Daga Ultra-Inert zuwa Kunnawa
Ko da yake sanding da farko magani ne na jiki, yana kuma haifar da canje-canje ga kaddarorin sinadarai:
· Ƙarfin ƙarfi mai ƙarfi: PTFE mai tsabta yana da ƙarfin ƙarancin ƙasa (18-20 mN / m), tare da kusurwar lamba ta ruwa akan 108 °. Bayan yashi, sabbin filaye masu daɗaɗɗa da sarƙoƙin ƙwayoyin cuta suna fallasa wuraren aiki masu ƙarfi na ɗan lokaci, suna ɗaga ƙarfin saman sama da 40 mN/m. Digon ruwa ya bazu yana jika saman, yana nuna yanayin ruwa na ɗan lokaci, wanda ke shuɗewa a hankali a kan lokaci.
Gabatarwa na wucin gadi na ƙungiyoyin aiki na polar: Babban ƙarfin kuzari yana haifar da halayen tsakanin sarƙoƙi na kwayoyin PTFE da suka karye da oxygen / danshi a cikin iska, suna haifar da ƙungiyoyi masu aiki na polar nan take kamar carbonyl (C = O) da hydroxyl (-OH). Waɗannan ƙungiyoyi suna ba da damar haɗakar sinadarai don ƙarin gyare-gyaren sinadarai ko lamination na m.
