Hudu manyan ayyuka na pretreatment a aluminum gami surface karewa

Lokacin da bayanin martabar aluminium extrusion profile pretreatment a kan-site a lokacin samarwa, da lalata juriya da na ado kaddarorin na aluminum surface za a iya yadda ya kamata inganta.

Aiki na 1: Ta hanyar jiyya mai jujjuyawar ƙasa kamar sandblasting da sinadarai etching, pretreatment yana haifar da ƙaramin tsari a saman don samar da wuraren ɗorawa na inji don murfin foda. Daidaitaccen yanayin da ya dace na iya haɓaka tasirin ƙwanƙwasa na inji.

Aiki 2: Ta hanyar jiyya kunnawa saman kamar pickling da alkaline etching, pretreatment yana cire inert oxide Layer a saman, fallasa wani sabon karfe surface da inganta surface sinadaran aiki. Maganin jujjuyawar sinadarai yana samar da fim ɗin juyawa mai amsawa akan saman don samar da wuraren haɗin sinadarai don sutura. Don bayanin martabar aluminium da aka yi amfani da shi a wasu taga da kofa masu tsayi na aluminium, ana iya buƙatar matakan jiyya na saman gaba biyu ko uku.

Aiki 3: Pretreatment yana rinjayar wettability da kuma interfacial bonding karfi tsakanin shafi da substrate, da muhimmanci inganta wettability na aluminum profile surface.

Aiki 4: Fim ɗin juyawa ko wasu yadudduka da aka bi da su da aka kafa a saman ta hanyar pretreatment suna aiki azaman tsaka-tsakin tsaka-tsakin tsaka-tsakin tsaka-tsaki, wanda ke sauƙaƙa ƙaddamar da damuwa tsakanin ma'auni da shafi kuma yana haɓaka ƙarfin haɗin kai.
