ʻO ka heluʻana o keʻano helumini koʻikoʻi - E alakaʻi maʻalahi me nā hiʻohiʻona

1. Hōʻikeʻike

Aluminum nā kūlana ma waena o nā mea e hoʻohana nuiʻia ai ka honua i nā meaʻenehana e pili ana i konaʻano kiʻekiʻe, Ke kū'ē neiʻo Corrosionion, a me ka formability.

Eia naʻe, ʻOiai nā hewa liʻiliʻi ma ke kaupaona kaupaonaʻana hiki i nā papa hana derail, ʻO nā kumukūʻai hoʻouna, a me nā helu helu hoʻohālikelike.

Ma kēia alakaʻi, Eʻimi mākou i nā waihona kālā o ke kumukūʻai alumini, Nā Kūlana Kūlana Kūlana, Nā Kūlana Pono, a me nā lua, e hoʻokaʻawale iāʻoe me kaʻike e koho pono ai i ke kaupaona alumini.

2. ʻO nā waihona kālā o ka alumini a me konaʻano

ʻO nā helu kino a Alminim nui o nā kumuwaiwai pilikino i lalo o nā helu kaupaona:

• Huakai (r): Kū-starder 2.70 g / cm³ (Oole 2,700 kg / m³).
• Malting Point: ~ 660 ° C-T-INCERACAVATA e kaupaona akā he mea nui no ka hoʻoiliʻana.
• Nā Kūlana maʻamau: 6061-T6, 7075-T6 (ʻO nāʻano hoʻohālikelike liʻiliʻi i ka ± 1-2%).

Nā mea'ē aʻe (E.g., Magnesum, Silikino) a me ka pasosity mai ka huki ana a iʻole ka loaʻaʻana o ka wikiwiki e like me ka ± 0.05 g / cm³, A laila hōʻoia mau i ka Datasheet kūikawā.

3. Kūlana maʻamau no ka heluʻana i ka paona alumini

Ke hoʻomaka pololei nei ke kaupaonaʻana o ke kaupaonaʻana o nā'āpana alumini e hoʻomaka me ka hoʻomaopopoʻana i nā loina matematika.

Inā no ka hoʻolālā hoʻolālā, Hoʻolālā Hoʻolālā, a iʻole keʻano hoʻohālikelike, ka loaʻaʻana o kahi kūlana kūlike a hilinaʻi i ka mea kūpono i hoʻohanaʻia ka nui o ka waiwai, e hōʻemi ana i ka ʻōpala a me ke kumukūʻai.

General Social

Ma kānaʻano, Hoʻoholo ʻia ke kaumaha o kekahi mea alumini me ka hoʻohana ʻana i ke kumu hoʻohālikelike kumu:

Ke kaumaha (kg)= Ka nui (m³)× ʻAiʻa (kg / m³)

• ʻO ka nui o ka alumini maʻamau maʻamau 2,700 kg / m³ (Oole 2.70 g / cm³) no nā māka maʻemaʻe, ʻoiai hiki ke ʻano liʻiliʻi ma muli o ka paʻa.
• Volume ua helu ʻia ma muli o ke ʻano a me nā ana o ka ʻāpana.

He mea koʻikoʻi ke kūlike o ka ʻāpana:
ʻO kahi kumu maʻamau o ka hewa nā ʻāpana like ʻole.

ʻo kahi laʻana, me ka hoʻohana ʻana i nā millimeters ma kahi o nā mika i ka helu ʻana i ka leo e hopena i nā hewa ma kahi helu o 1,000,000. E hoʻololi mau i nā ana i nā mika ke helu ʻana i nā ʻāpana SI.

ʻO keʻano kaulike maʻamau a Alminimum

E hoʻomāmā i ka helu ʻana no nā ʻano maʻamau, hoʻohana pinepine nā mea ʻenekinia i nā ʻano hana i loaʻa mua e hoʻohui i ka leo a me ka nui.

Aia ma lalo iho nā ʻōlelo hoʻohālikelike maʻamau i hoʻohana nui ʻia i ka ʻoihana, kēlā me kēia ma muli o ka ʻawelika o ka alumini 2,700 kg / m³.

Lawa kēlā me kēia (E.g., 0.00271, 0.00220) nā hualoaʻa mai ka hoʻololiʻana mm³ i m³ a me ka hoʻonuiʻana e ka hana o ka waiwai (2,700 kg / m³), Hāʻawi i ka paona kūpono i nā kilokilo.

ʻO nā hiʻohiʻona helu koho

Hoʻoloholo 1: Nā papa alumini

ʻO nā wahi pā 4 mm mānoanoa, 1,000 mm oiwn, a 2,000 MM Kiʻi loa:

W = 0.00271 × 4 × 1000 × 2000 = 21.68Kg

Hoʻoloholo 2: A me ke koʻokoʻo kūloko

Diameter = 50 mm, Lole = 1,000 mm:

W = 0.00220 × 50 ^ 2 × 1000 = 5,500g = 5.5kg = 5.5kg

Hoʻoloholo 3: Tube Hollow Alumi Kauwa

I waho o ka diameter = 60 mm, Lohi 5 mm, Lole = 1,200 mm:

W = 0.00879 × 5 ×(60-5)× 400 = 2,926.2g≈2.93kg

ʻAʻole maʻalahi kēia mau hiʻohiʻona i ka loaʻaʻana o ka manaʻo akā lawelawe pū nō hoʻi e like me keʻano o nā papa hana no ka haʻiʻana, Ka Hoʻoulu, a me nā kaʻina hana.

4. Aiko, Nā mea kūʻaiʻili, a me nā hoʻoponopono maoli maoli

I nā hoʻonohonoho hoʻonohonoho, Waihona:

• Nā Kūlana Kūʻai: ± 0.2 mm mānoanoaʻokoʻa e hoʻohui i ± 2% mau hewa kaumaha.
• Factor kumu: E komo i ka 5-10% mau mea hou no ka machining a me ka nalowaleʻana i ka nalowale.
• Potiwale & Nā pāpale: E lilo paha nā'āpana i nā'āpana ~ 1% density i nā leo; Hoʻohuiʻo Anodizing ~ 0,02 kg / m².

NOEHUI, E hoʻohui i kahi palekana palekana-pinepine +7%-ʻO nā helu helu ma mua o ke kauoha.

5. Nā hewa maʻamau a pehea e pale ai iā lākou

1. Ulana mismatch: E hoʻohuli ana i ka mm³ i m³ pololeiʻole e hoʻonui i nā hewa e 1 000³.
2. Ka nānāʻana i nā'āpana hollow: Ke heleʻole nei i ke alakaʻiʻana i ka diameter i loko o 30-50% overretimation.
3. Ka pauʻana o ka loliʻana: Ke manaʻo nei 2.70 g / cm³ no nā alloys hiki i nā hualoaʻa e hiki i nā hualoaʻa e loaʻa ana ma 1-2%.
4. Skipping scrap factor: Ka haʻaleleʻana i ka pohō matchrestietes idesterstimates i nā kauoha ma 5-10%.

Nā helu helu pāluaʻelua, subtracka void voloues, a puni i ka lōʻihi o ka lōʻihi o ka lōʻihi.

6. ʻO ka papa inoa o nā alloys aluminum

ʻO ka Alluinum Alloys ka mea maʻamau, a ke hōʻike nei kā lākou papa i nā'āpana o nā hui, Ke kaʻina hanaʻana, a me nā noi a lākou e kākoʻo ai.

ʻO ka hoʻomaopopoʻana he mea nui kēia mau helu no ke kohoʻana i nā mea kūpono no kaʻenehana kūikawā, hana ai.uk, a me nā koi kūpono.

Ma lalo o nāʻano papa inoa kiʻekiʻe loa iʻaeʻia:

E pili ana i ke kaʻina hana

Nā alluinum alumini

Hoʻolālāʻia kēia mau hana no ka deformation plastic a me nā mea maʻamau i loko o nā'āpana, Nā papa, Kuhi, tuku, a me nā hoʻoponoʻana ma nā kaʻina hana e like me ka holoʻana, hānehi, a iʻole ke kalaʻia.

Ua kohoʻia nā allona a Alminim:

• ʻO nā alloys hou: Hoʻoikaika muaʻia e ka hana anuanu (E.g., Strain Hardening). Hoʻoloholo: 3Xxx a me 5xxx series.
• ʻO nā alloys wela: Loaʻa ka ikaika ma o ka hoʻonāʻana i ka hopena wela a me ka wā kahiko. Hoʻoloholo: 2XXX, 6XXX, a me 7xxx faile.

Hūnā iā Aluminum Alloys

Hūnā. Ua hoʻohana muaʻia nā alloys no nā hana hana me nā geomex paʻakikī e paʻakikī i ka paʻakikī o ka hoʻokumuʻana.

ʻO kēia mau alloys maʻamau i ka ikaika o ka mīkini i hoʻohālikelikeʻia e hoʻohālikelikeʻia e nā alloys i hanaʻia akā ua manaʻoʻia no ka hale kūʻai. Komo lākou:

• Al-Ae (HELULUM-Silcearch): ʻO ka mālamaʻana i ka hanaʻana a me nā pale pale.
• Al-c (Aeminumum-keleawe): Ikaika kiʻekiʻe akāʻoi aku ka paleʻana.
• AL-mG (Aluminum-Magnesium): ʻO ke kū'ēʻana o ka corrossion maikaʻi.
• Al-zn (Alumula-zinc): Ikaika kiʻekiʻe akāʻoi aku ka paleʻana o ka corrosion.

E pili ana i ka hui pūʻana a me nā hana hana

Ua kūkuluʻia ka hui Aluminum e hoʻokumu i kahi'ōnaehana hoʻolālā heluʻehā no nā alloys a me kahi papa heluʻekolu no nā alloys.

ʻO ka 1xxx i 7xxx Series e hōʻike i nā pūʻulu hana maʻamau maʻamau:

HE MAU LOA HOOLAHA

Ma kahi o nāʻano maʻamau, makemake nui Aluminum-lilumum (Al-Li) ua kūkuluʻia no nā noi aerospace, Hāʻawi i nā kaulike ikaika ikaika loa a me nā mea kaupaona e hoʻonui ai i ka paleʻana.

E pili ana i nā noi e hoʻohana ai

Hiki ke heluʻiaʻo Alumini Alloys e kaʻoihana a iʻole ka noi a lākou e lawelawe ai, e noʻonoʻo ana i ka uluʻana o ka uluʻana ma waena o nā'āpana:

• Kūkulu hoʻi: Nā Kūlana Window, nā pālā haki, Pūnaehana Pūnaewele.
• Ke Kaaloa: Nā pā lima kino, E hoʻomaʻamaʻa i nā kaʻa kaʻa, nā mokulele mokulele.
• Lako uila & Nā leka uila: Radiators, Nā Pahu Kāla, sinks wela.
• Kōkele: Nā mea inu inu, Nā pāpale, ʻO nā lāʻau kai.
• AerERPPACE & Reflan: Nā Kūlana Kūlana Kūʻai Kūʻai, Nā kākuhi rocket, nā hoʻopuni radiar.

ʻO ka helu helu Multibansal i hanaʻia ma ka hoʻomaʻamaʻa

He mea nui ia e hoʻomaopopo i kēia mau'ōnaehana papa inoaʻole. ʻo kahi laʻana, an anloy like 6061-T6 hāʻule ma lalo:

• 6Xxx series e pili ana i kānaʻano (Al-mg-si),
• Deformed aluminum alloy Hoʻokumuʻia ma ke kaʻina hana,
• A mae pū kekahi ma lalo nā noi lawena Ma muli o kona hoʻohanaʻana i ka hoʻohanaʻana i nā papa kaʻa.

Hāʻawi kēia helu helu helu helu i ka maʻalahi a me ka pololei i ke kohoʻana i ke koho a Aluminim alloy no kekahi hanaʻenehana.

7. Hopena

ʻO ka helu kaulike aluminite alumini, incrutural integrity, a me nā mea hana kūpono.

E ka hoʻolimalima Nā'ōlelo kiko'ī, Waihona Kūpono nā mea maoli maoli, a hoʻohui pū Nā Hana Hana, Hiki i nā mīkini hana a me nā hui hui ke koho i nā mea hoʻohana, hoʻemi i ka pauʻole, a e hoʻokō i nā kiko'ī hoʻonohonoho paʻa.

8. FaqS

1. He aha ka hana maʻamau o ka alumini?
   Maki 2.70 g / cm³, akā, hiki i nā kikowaena kiko'ī kiko'ī ke papa inoa 2.68-2.80 G / cm³.
2. Pehea wau e helu ai i ke kaupaonaʻana o kahi pahu alumini?
   E hoʻohana w = 0.00220 × d2 × lw = 0.00220 \Times D ^ 2 Times LW = 0.00220 × D2 × L (D a l i mm).
3. Hana i nā alloys a me nā alluinum e pili ana i nā helu kaupaona?
   ʻAe-density varies ±-1-2%; E hōʻoia mau i kaʻikepiliʻenehana a Alloy.
4. Aia nā helu helu pūnaewele no ka paona alumini?
   Nui nā mea e nānā ai i nā helu helu eʻae iāʻoe e kuhikuhi i keʻano, Nā 'Youlelo'Āina, a me ka wiwo ole.
5. Pehea ka hanaʻana i nā wānana kaupaona cead?
   Hoʻohana nā mea hana cad i nāʻano geometric like, Ke hāʻawi nei i ka helu helu ± 1% inā hiki iāʻoe ke komo pololei i nāʻano kūpono a me nā dimensional.
