Dalilan da ke tattare da rashin daidaituwar launi na fim ɗin alloy oxide na aluminum

Dalilai uku masu yuwuwar launin fim ɗin bayanin martabar aluminum oxide ba iri ɗaya bane:

(1) Lokacin da bayanin martabar aluminum ya kasance anodized, akwai manyan bambance-bambance a cikin yanki na aiki, kewayon juyawa, gefen da matsayi na tsakiya, lambar sadarwa, sabuntawa, da musayar, wanda ke haifar da fim ɗin launi mara daidaituwa. Matakan rigakafin sun haɗa da ƙaramin kewayon lilo yayin anodizing bayanin martabar aluminium da kuma watakila jiyya a tsaye, kodayake rashin ƙarancin zafin jiki na iya haifar da samuwar taswira ko tabo, wanda ba shine abin da ake nufi ba.

(2) Lokacin da aluminum clad sassa aka karkashin lalata, ta hanyar yanke, m alclad nasa ne high quality aluminum, kewaye ciki Layer ne daban-daban aluminum, biyu aluminum bambance-bambancen karatu, don haka hadawan abu da iskar shaka bayan "benign vitiligo" kamar spots. Abokin ciniki sau da yawa ba su fahimci wannan abu ba, masana'antun ya kamata su yi ƙarin bayani don bayyana aikin, bayyana dalilin da ya sa kuma ta yaya, don kauce wa rashin fahimta.

(3) Matsaloli tare da aiwatar da aiki

Ba duk datti aka cire ta wurin asalin fim ɗin na gida ba kuma maganin caustic na aikin aikin bai isa ba;

Har yanzu saman yana da asali bayan alkali etching tun lokacin da ba a amfani da sarrafa haske nan da nan;

da workpiece ta hulda a lokacin watsa tare da waje abu.

Lokacin da bidiyon ya nuna launi mara daidaituwa, yakamata a yi matakin da ya dace don magance matsalar daga kusurwoyi da yawa.

Laifi mai karatu ya kira tambayar workpiece ta bayan alkali etching conductive oxide fim da wuya a samu dalilan da ya sa alkaline etching ruwa aluminum ion tarawa ne ma high, bayan ware da yawa dalilai da wuya a samar da conductive oxide fim, kai cikin. lissafi ko high aluminum ions alkali etching bayani, da sauran ce alkaline lalata bayani ne sosai lokacin farin ciki. Amma saurin lalata alkali baya sauri. Sa'an nan marubucin ya ba da shawarar canza alkaline lalata bayani, saboda bayan alkaline etching ruwa amfani da dogon lokaci zai aluminum ion tarawa na wuce haddi, aluminum ions a kan surface na workpiece da wuya elution, haka shafi aluminum surface da conductive oxide bayani lamba. don haka yana shafar samuwar fim din oxide. Wani shawara shi ne cewa idan unconditional maye alkaline etching bayani, da workpiece bayan alkali etching bayan ruwa kurkura nan da nan bayan da ya kwarara na ruwa kurkura, sa'an nan wani haske a cikin wani hydrofluoric acid dauke da mayar da hankali nitric acid, sa'an nan kurkura sosai bayan gudanar hadawan abu da iskar shaka magani. Bayan masu karatu a wayar tarho sun ce bayan alkali etching da ruwan zafi kuma tasirin yana da kyau sosai. Marubucin shi ne gwaninta, kuma a cikin ruwan zafi bayan ruwan zafi da kuma nan da nan immersed cikin ruwa da sauri bar, don hana workpiece da bushe saboda hadawan abu da iskar shaka da kuma rinjayar da samuwar conductive oxide fim.
