Aluminium keychains, raws li lub npe qhia, yog ua los ntawm txhuas. Nov yog saib ze dua ntawm lawv cov khoom siv:
I. Khoom siv tseem ceeb: aluminium
Aluminium khoom: Aluminium yog ib hom ntawm lub teeb hlau nrog tsawg ntom, zoo ductility thiab muaj zog corrosion kuj. Cov khoom no ua rau txhuas zoo tagnrho rau kev ua lub teeb yuag, ruaj gadgets zoo li keychains.
Aluminium Alloys: Hauv daim ntawv thov, ntshiab txhuas tsis tshua siv los ua cov saw tseem ceeb ncaj qha, thiab txhuas alloys feem ntau siv. Aluminium alloys txhim kho cov khoom siv dag zog ntawm txhuas los ntawm kev ntxiv lwm cov ntsiab lus xws li tooj liab, magnesium, thiab zinc, xws li nce lub zog, hardness, thiab abrasion tsis kam. Cov khoom siv txhuas txhuas muaj xws li txhuas-magnesium alloys thiab aluminium-zinc alloys, ob qho tib si muaj cov khoom siv zoo thiab corrosion kuj.
II. Lwm cov ntaub ntawv muaj peev xwm (txhim kho lossis kho kom zoo nkauj):
Plastics: Cov yas tuaj yeem siv los ua cov khoom siv rau kev tsim cov txhuas keychains, xws li cov nplhaib tseem ceeb thiab cov khoom sib txuas. Yas yog lub teeb yuag, yooj yim rau kev ua haujlwm thiab tus nqi qis. Ua ke nrog aluminium, nws tsim lub nplhaib tseem ceeb uas yog ob qho tib si zoo nkauj thiab siv tau.
Hlau Fittingss: Ntxiv rau txhuas thiab yas, txhuas keychains tuaj yeem siv rau lwm yam hlau fittings, xws li stainless hlau rings thiab tooj liab ornaments. Cov hlau fittings no tuaj yeem txhim kho cov kav ntev thiab kev zoo nkauj ntawm keychain.
Cov khoom siv kho qhov saum npoo: Txhawm rau txhim kho cov tsos thiab kev tiv thaiv corrosion ntawm aluminium keychains, nws feem ntau yog kho qhov chaw. Kev kho deg feem ntau suav nrog anodizing, pleev xim thiab plating. Cov kev kho mob no tsim cov yeeb yaj kiab tiv thaiv ntawm aluminium nto uas tiv thaiv oxidation los yog corrosion, thaum tseem txhim kho cov keychain zoo li.
