Pepa Alumini vs Pepa Alumini: Fa'amatalaga Mafiafia ma Eseesega Fa'aoga
Alumisina pepa mafiafiao le faamama muamua lea e tusi ta'ai e pule uma fa'atau i le fomu su'esu'e, ae o lo'o avea pea ma ta'iala sili ona sese i le fefa'ataua'iga alumini i le lalolagi.
Lalo 6.35 mm (0.250 i totonu.) o le oloa e ta'ua o le laupepa; luga ae, ipu.
Ole laina e tasi ile ASTM B209, ISO 6361 ma GB/T 3880 fa'aosoina se fa'aoso o metallurgical, i'uga fa'atauva'a ma fefa'ataua'iga e mafai ona fa'atuputele-pe fa'ate'a-le tau o le poloketi e fa'alua-numera pasene.
O lenei tusiga o loʻo faʻamatalaina le cascade, fa'aopoopo i ai laulau fa'atusatusaga maualuga e fa, tali le 12 fesili e masani ona su'e Google e tagata fa'atau, ma faʻaalia pe faʻafefea e Eco Alum Co., Ltd. teuteu 1 680 t o CO₂ fa'atusaina e ala i le fesuia'i mai 10 mm ipu i 5 mm pepa i luga ole a 300 000 m² taualuga logistics.
1. Aisea 6.35 mm? – Talafaasolopito ua tusia i se numera
I totonu 1954 ASTM Komiti B-07 mana'omia se tipi manino mo le mafai ona ta'avale vevela i luga o le 144-inisi fou vili fa'aliliu.
¼ inisi (6.35 mm) o le fua sili ona manifinifi e mafai ona ta'avale e aunoa ma ni ta'e mata i le lautele atoa.
Na kopiina e ISO le tapulaa i totonu 1967 ina ia fa'amaopoopo feso'ota'iga a le Atelani ma le Pasefika.
I le fitusefulu tausaga mulimuli ane, o loʻo ola pea le numera-e le ona e le mafai ona taʻavale fua vevela vevela, ae ona o tulafono uma i lalo (toto, UT, togafiti vevela, vaivai) ua calibrated i ai.
2. Fa'asologa o filifili i se tepa
Laupepa (≤6.35 mm)
Cold-roll → Degrease → Anneal poʻo fofo-vevela-treat → Tension-level → Trim → Eddy-current inspection → Coil poʻo le pusa laupapa.
Ipu (>6.35 mm)
Hot-roll po'o DC-cast → Fa'aulu mata uma → Stretcher-level (0.5–2 % palasitika tiga) → 10 MHz su'esu'ega ultrasonic → Plasma po'o le va'aiga tipi → Fa'amau fa'amau.
3. Microstructure & oso fa'ainisinia
Pepa taai malulu o lo'o tauaveina se fua fa'atatau o saito panikeke ≥5:1, tu'u maualuga r-taua mo ata loloto ae maualalo gau gau.
E toe fa'a'aisa le ipu fa'a'a'ai vevela i fatu equiaxed; lapo'a lapo'a fatu e fa'atupuina ai le malosi e maua ae faatoluina le laina pi'o.
