Fasahar maganin saman fuska
Anodizedallon aluminum
Da farko, menene tsarin anodizing?Anodizing wani tsari ne na lantarki wanda ke samar da wani kauri mai yawa na oxide akan aluminum.
Al2O3 wani sinadari ne da ba ya canzawa, yana da mafi girman tauri tsakanin oxides, kuma yana da juriya sosai ga yanayi. Ko da Layer oxide ya haɗu da wuta, aluminum yana narkewa amma Layer oxide ba zai canza ba. Ba ƙari ba ne a ce anodized alumina shine Rolls Royce na aluminum panel. A gaskiya ma, ba ƙari ba ne a tambayi wace hanya ce ta maganin saman za ta iya cimma irin waɗannan halaye masu yawa?
Panel ɗin aluminum na fluorine
Ana fesa allon aluminum na fluorocarbon a saman aluminum ta hanyar tsarin gyaran fenti. Duk da cewa an ƙara murfin fluorocarbon tare da resin fluorine don inganta aikin, tsarin polymer na fim ɗin fenti zai ci gaba da haskakawa ta hanyar fashewar hasken ultraviolet, da niƙa da kuma barewar haske.

Mai sauƙin tsaftacewa
Yawancin bangon labulen aluminum na fluorocarbon, wanda aka sanya shi na tsawon watanni 3 kawai zai bayyana shigar ruwa da gurɓataccen kwararar ruwa a tsaye, farantin aluminum na fluorocarbon bayan yawan ƙura da ke sha, tare da tsawaita lokaci, tarin gurɓatattun abubuwa yana ƙara tsananta kuma yana ƙaura tare da saman porous zuwa cikin rufin, yana shafar bayyanar bangon labulen sosai.
Idan aka duba ta hanyar na'urar hangen nesa, ana iya ganin fim ɗin fenti na fluorocarbon a girman da ya kai sau 500, yana kama da tsarin sponge mai ramuka.
Saboda yawan girman allon aluminum mai anodized, ba a iya ganin tsarin a cikin girman 500x ba, don haka dole ne a ƙara girmansa zuwa 150,000x. Sakamakon ya kasance mai ban mamaki. Fim ɗin oxide kamar tsari ne mai tauri ba tare da wani gibi na katangar ba, mai tsayi sosai a saman aluminum substrate, allon aluminum zuwa mafi girman matakin magani dole ne ya zama No.1!
Layin oxide na allon aluminum mai anodized yana kama da layman yumbu na corundum, saman ba ya ɗaukar nauyi kuma baya shan ƙura. Tsarin mai yawa yana sa gurɓatattun abubuwa su shiga ba zai yiwu ba, kuma gurɓatattun abubuwa da ke iyo a saman za su shafe su da ruwan sama. Muddin ana tsaftace su da kyau, bangon zai iya zama sabo tsawon shekaru.
Fluorine carbon aluminum panel a saman fluorine polymer resin shafi (wanda za a iya fahimta don filastik), ɗaukar nauyin adsorption datti cikin sauƙi, kuma a cikin haske zai yi tauri a hankali, yana ƙara datti, rataye bar datti a cikin fim mai porous, yana samar da gurɓataccen kwararar ruwa bayan ruwan sama ya wanke, koda tare da sabulun sinadarai mai ƙarfi yana rage matakin ƙura na ɗan lokaci, kuma zai haifar da bangon labule ya tsufa.

Bisa ga binciken da aka yi a sama, saboda hanyoyin magance saman da aka yi amfani da su daban-daban, akwai sararin ciki a cikin fim ɗin fenti mai fluorocarbon wanda yake da sauƙin lalacewa. Bayan tsatsa mai filamentous, saman yana iya barewa, kumfa, fashewa ko tsagewa. Bayan yanayi ya yi kyau, saman fim ɗin fenti zai yi foda mai kyau, kuma sheƙi da launi suna raguwa sosai, wanda ke haifar da lalacewar bayyanar saman.
Sabanin haka, allon aluminum mai anodized, bayan kusan shekaru 70 na gwaninta a gida da waje, matuƙar tsaftacewa da kulawa na yau da kullun, gidan zai iya jurewa.
An kafa kamfanin PPG Industries a shekarar 1883, kamfanin fenti na waje mafi girma a duniya, ya yi amfani da aluminum mai anodized don hedikwatar gudanarwa da cibiyar bincike da haɓaka, wadda aka gina shekaru 34 da suka gabata ba tare da kulawa ta yau da kullun ba.
A cikin aikin ofishin PONT DE SVRES, bangon labulen aluminum mai anodized ya tsufa sosai, yana da shekaru 46, kuma ba a yi masa gyaran fuska akai-akai ba.
