Maganin Sama na Polytetrafluoroethylene (PTFE)

A matsayin mai sana'a tushen masana'anta na PTFE high-zazzabi yadudduka, Jiangsu Aokai New Materials zai gabatar da surface jiyya na polytetrafluoroethylene (PTFE).

PTFE yana da kyakkyawan juriya mai girma da ƙarancin zafin jiki, ƙwaƙƙwaran juriyar lalata sinadarai, ƙarancin juzu'i da kaddarorin sa mai mai kai. Ana amfani da shi sosai a cikin kayan lantarki, injina, kayan aikin sinadarai, sararin samaniya, biomedicine da sauran fagage, wanda hakan ya sa ya sami sunan 'Sarkin Filastik' . Koyaya, saboda rashin kuzarin sinadarai da ƙarancin kuzari, PTFE yana da wahala a haɗa shi da wasu kayan, wanda ke iyakance aikace-aikacen sa zuwa wani lokaci. Don inganta mannewa tsakanin PTFE da kayan daban-daban, yawanci ana amfani da hanyoyin don haɓaka aikin PTFE. Don samfura daban-daban, Sabon Kayayyakin Aokai gabaɗaya yana amfani da hanyoyin gyara saman PTFE masu zuwa.

1. Rike Maganin Sinadari

Maganin sinadarai na sodium-naphthalene  shine ɗayan ingantattun hanyoyin don gyare-gyaren PTFE. Tare da sauƙi tsari da ƙananan farashi, shine zaɓin da aka fi so a cikin samarwa mai amfani a masana'antar PTFE ta Aokai New Materials.

Maganin sodium-naphthalene galibi yana amfani da maganin etching don amsa sinadarai tare da PTFE, yana cire wasu zarra na fluorine daga saman. Wannan yana barin Layer na carbonized kuma yana gabatar da ƙungiyoyin polar kamar ƙungiyoyin hydroxyl, ƙungiyoyin carbonyl da shaidu marasa ƙarfi. Waɗannan ƙungiyoyin polar suna haɓaka ƙarfin farfajiya na polymer, rage kusurwar lamba kuma suna haɓaka wettability, don haka juya PTFE daga waɗanda ba a haɗa su cikin haɗin gwiwa.

2. Hanyar Haɗaɗɗen Injiniya

Lokacin da polymers aka hõre daga waje sojojin (misali, murkushe, nika, gogayya, da dai sauransu), macromolecular sarƙoƙi karya da kuma sha sinadaran halayen, ciki har da mechanodegradation, mechanochemical crosslinking, mechanochemical grafting, toshe copolymerization da danniya- kunna polymerization. Waɗannan ana kiran su da halayen mechanochemical polymer.

A cikin haɗin gwiwar injiniyoyi, ana shafa saman polymer mai rufin m. Ta hanyar aikin injiniyoyi, saman polymer yana jure wa injina don samar da radicals na kyauta na macromolecular, wanda sannan ya samar da covalent bond tare da ƙwayoyin mannewa, ƙirƙirar ƙirar haɗin gwiwa mai ƙarfi kuma yana haɓaka ƙarfin haɗin gwiwa sosai.

3. Hanyar narkewa mai zafi

Babban ka'idar gyaggyarawa saman PTFE ta hanyar narkewar zafin jiki mai zafi shine: a yanayin zafi mai zafi, ana canza yanayin halittar crystalline na saman PTFE, da haɓaka-makamashi mai ƙarfi, kayan haɗin kai cikin sauƙi kamar SiO₂ da Al foda suna saka. Bayan sanyaya, wani gyare-gyaren Layer mai ɗauke da abubuwa masu ɗaurewa yana samuwa akan saman PTFE. Tunda kwayoyin halitta na kayan haɗin gwiwa sun shiga cikin farfajiyar kwayoyin halitta na PTFE, karya haɗin yana buƙatar lalata intermolecular, yana haifar da ƙarfin haɗin gwiwa.

4. Hanyar Radiation

Ana sanya PTFE a cikin monomers masu amsawa kamar su styrene, fumaric acid, methacrylates da sauransu, sa'an nan kuma an lalata su tare da Co-60 . Wannan yana haifar da sinadarai dasa polymerization na monomers a kan PTFE surface, forming wani graft polymer Layer da sauki bond. Grafting kuma roughens surface, ƙara bonding yankin da kuma inganta bonding ƙarfi.

5. Fasahar Jiyya na Plasma

Maganin Plasma ɗaya ne daga cikin fasahar haɓakawa da sauri don gyare-gyaren PTFE a cikin 'yan shekarun nan.

Mahimmancin wannan fasaha shine sanya samfurin a cikin na'urar da aka keɓe na maganin plasma, inda ion bombardment ko implantation ya karya ginshiƙan kwayoyin halitta ko gabatar da ƙungiyoyi masu aiki a saman polymer, kunna saman don cimma gyare-gyare. Ions na iya zama inert gas, gas mai aiki da sinadarai ko abubuwa na ƙarfe. Bama-bamai tare da iskar gas na iya canza tsarin saman polymer.
