Wannan masana'anta na iya zama mai hana mai ba tare da wakili na gama fluorocarbon ba, wanda wani mataki ne na ci gaban koren ci gaban masana'antar masaku

Tufafi mai hana mai shine nau'in masana'anta na tufafi masu kyau, wanda ba shi da sauƙi a shafa mai, sauki tsaftacewa, rage farashin kulawa ga masu amfani, don haka ya shahara sosai a kasuwan masu amfani.




Fluorocarbon mahadi (Farashin PFC), kamar yadda karewa jamiái ga low surface makamashi yadudduka, zai iya inganta ingantaccen kayan hana ruwa / mai-hujja na yadudduka. Musamman, polymers fluorocarbon dogon sarkar da zarar sun zama manyan kayayyaki a kasuwa. Duk da haka, fluorocarbons na iya shafar lafiyar ɗan adam da amincin muhalli yayin amfani da su, kuma abubuwan da suke samarwa ba su da sauƙi a lalata su a cikin muhalli. Tarayyar Turai ta sanya takunkumi kan siyarwa da amfani da PFOS da PFOA a ciki 2008. Saboda haka, ganowa da haɓaka sabbin abubuwan maye ya zama wani muhimmin ɓangare na masana'antar sinadarai na yadi da rini da masana'antar gamawa a duk faɗin duniya..




Kwanan nan Jami'ar Columbia ta sanar da wani sabon nau'in masaku mai hana mai wanda baya amfani da PFC wajen shirye-shiryenta. Masu binciken suna ƙara rubutu zuwa saman kowane fiber, da sarrafa sinadarai na saman kayan fiber ta hanyar sarrafa girman da tazara na rubutu, ta yadda za a gane aikinsa na hana mai. Sakamakon gwaji ya nuna cewa yadudduka ba sa jika lokacin da tashin hankali ya yi ƙasa da 23.9mn / m, kuma ya yi tasiri mai kyau wajen kawar da man fetir, man zaitun da man kasko.




Ka'idar shiri shine kamar haka: saman masana'anta shine hydrophilic bayan etching plasma. Babban adadin ƙungiyoyin hydroxyl da aka kafa bayan hydrolysis na TEOS na iya samar da Layer dauki akan masana'anta. Bayan warkewa, za a iya gina wani tsarin micro-nano tare da wasu roughness. Haka kuma, bayan nutsewa cikin maganin silanol, babban adadin kungiyoyin silanol a saman masana'anta na iya amsawa tare da siloxane na 1, 3-dichlorotetrachloromethyldisiloxane, don haka rage karfin saman sa. Ƙarƙashin tasirin synergistic na m tsarin da low surface makamashi, masana'anta yana da dukiyar hana mai.




Bugu da kari, saboda covalent bond tsakanin saman abu da fiber, yana iya wanzuwa a tsaye a yanayin wanka ko sawa, wanda ke tabbatar da dorewarsa zuwa wani matsayi. Wannan binciken yana ba da kwatance don haɓaka ci gaba mai dorewa na samfuran masaku masu aiki.
