Menene ƙayyadaddun wuraren da'irar aluminum don kayan girki?
Aluminum da'irar kuma ana kiranta da takardar da'irar aluminum, wanda shine ingantaccen abu don yin girki kamar kwanon aluminum, aluminum tukunya, aluminum shinkafa cooker, aluminum kayan dafa abinci, aluminum matsa lamba cooker da sauransu. Aluminum cookware yana da abũbuwan amfãni daga haske, m, low farashin, dumama sauri da uniform, babu tsatsa da sauƙin tsaftacewa, amma ba za a iya amfani da kayan dafa abinci na da'irar aluminum don dafa acidic ba, alkaline ko abinci mai gishiri. Tare da takamaiman rarrabuwa na kayan dafa abinci, samfuran aluminum suna da ƙarin samfura da aikace-aikace.
An fahimci cewa kayayyakin aluminum na yau da kullun sun kasu zuwa simintin gyare-gyare da tambari iri biyu. Ana kula da samfuran aluminium ɗin ta hanyar goge goge, tsarin karfe yana kwance, akwai wasu lahani na simintin gyaran kafa. Don hatimi samfuran aluminum, an wanke saman fari, ta hanyar yashi da goge goge na inji, saman yana da fim din oxide na halitta, amma kaurin fim ɗin shine kawai 0.01-0.15μm, bakin ciki ne kuma bai yi daidai ba, yana da sauƙi ya zama ɓarna na inji ko lalacewa. Yayin da'irar aluminum takardar don kayan dafa abinci samfuri ne mai hatimi wanda aka anodized don ƙirƙirar fim ɗin oxide akan saman sa. Fim ɗin oxide gabaɗaya lokacin farin ciki 5-20μm, uniform da yawa, karkashin aikin alkali, fim din bai lalace ba 100 seconds. Saboda haka, da'irar aluminum ita ce mafi kyawun samfurori don yin kayan dafa abinci, yana da kyawawan kamanni, sauki cire datti, mai ƙarfi juriya na lalata, juriya mai ƙarfi.
