Cilmiga caanka ah: kala duwanaanshaha barta dhalaalka ee aluminium alloys

Dulmar

Aluminiumku waa bir cajiib ah, lagu yaqaan wax-qabadkeeda, karti shaqo, iyo guryaha fudud. Iyada oo dhibic dhalaalaysa oo ku filan in ay faa'iido u leedahay tiro badan oo codsiyo ah, La yaab maaha in curiyahani yahay kan saddexaad ee ugu badan qolofka dhulka iyo birta aan birta ahayn ee ugu badan ee loo isticmaalo birta ka dib.. In boostada blog this, Waxaan sahamin doonaa barta dhalaalka aluminium, saamaynta ay ku leedahay aluminium aluminium kala duwan, arrimaha saameeya hantidan muhiimka ah, codsiyadeeda, iyo sida ay ula mid tahay biraha kale.

Shaxda dhibicda dhalaalaysa ee Aloysyada aluminiumka

Meesha dhalaalaysa ee aluminiumku waa hanti aasaasi ah oo saameeya isticmaalkeeda warshado kala duwan. Meesha dhalaalaysa ee aluminium saafi ah waa 660.32°C (1220.58°F). Si kastaba ha ahaatee, marka walxaha kale lagu daro si ay u sameeyaan aluminium alloys, barta dhalaalka ayaa laga yaabaa inay isbedelaan. Kuwa soo socdaa waa jaantus barta dhalaalaysa oo siddeed taxane ah oo aluminium ah oo la been abuurtay:

Taxane Meesha dhalaalaysa (°C) Meesha dhalaalaysa (°F)
1000 Aluminium Taxane ah 643 – 660 1190 – 1220
2000 Taxane Aluminium Alloy 502 – 670 935 – 1240
3000 Taxane Aluminium Alloy 629 – 655 1170 – 1210
4000 Taxane Aluminium Alloy 532 – 632 990 – 1170
5000 Taxane Aluminium Alloy 568 – 657 1060 – 1220
6000 Taxane Aluminium Alloy 554 – 655 1030 – 1210
7000 Taxane Aluminium Alloy 476 – 657 889 – 1220

Qaybahani waxay muujinayaan in isku-darka walxuhu ay si weyn u bedeli karaan barta dhalaalka si ay ugu habboonaato codsiyada gaarka ah.

Qodobbada dhalaalay ee Aloysyada Aluminiumka ee Caadiga ah

Siddeedda taxane ee daawaynta aluminium ee waaweyn ee been abuurka ah waxay leeyihiin darajooyin alloy ah oo si weyn loo isticmaalo. Jadwalka soo socda ayaa dooranaya qaar ka mid ah si uu u muujiyo kala duwanaanshaha barta dhalaalka ee u dhigma:

Qaabka Alloy Taxane Meesha dhalaalaysa (°C) Meesha dhalaalaysa (°F)
1050 1000 646 – 657 1190 – 1210
1060 646.1 – 657.2 1195 – 1215
1100 643 – 657.2 1190 – 1215
2024 2000 502 – 638 935 – 1180
3003 3000 643 – 654 1190 – 1210

Waxyaalaha saameeya barta dhalaalaysa ee aluminiumka

Dhowr arrimood ayaa saameyn ku yeelan kara barta dhalaalka aluminiumka iyo alwaaxyadeeda:

  • Qaybaha Alloying: Joogitaanka walxaha alloying sida copper, magnesium, silikon, iyo zinc waxay kor u qaadi kartaa ama hoos u dhigi kartaa barta dhalaalka, iyadoo ku xiran isdhexgalka ay la leeyihiin aluminium.
  • wasakhda: Xataa qadarka wasakhda ah ee raadraaca waxay saamayn kartaa barta dhalaalka. Tusaale ahaan, birta, taas oo inta badan ku jirta sida wasakhnimo, hoos u dhigi kartaa barta dhalaalka.
  • Taariikhda kulaylka: Taariikhda kulaylka ee aluminiumka, oo ay ku jiraan daawaynta kulaylka hore ama habaynta, waxay sifayn kartaa qaab-dhismeedka hadhuudhka waxayna saamayn kartaa barta dhalaalka.
  • Farsamooyinka Habaynta: Farsamooyinka processing kala duwan, sida xoojinta degdega ah ama biraha budada ah, waxay u horseedi kartaa qaab-dhismeedyo yaryar oo aan dheellitirnayn oo leh dhibco dhalaalid oo kala duwan.

Codsiyada Barta dhalaalaysa ee Sare ee Aluminium

Barta dhalaalka sare ee aluminiumka iyo aluminiumkeeda ayaa ka dhigaya inay ku habboon yihiin codsiyo heerkul sare ah:

  • alxanka iyo birta: Aluminium barta dhalaalka sare waxay u oggolaaneysaa alxanka xooggan iyo farsamooyinka birta, kuwaas oo lagama maarmaan u ah samaynta dhismayaal iyo qaybo kakan.
  • Kuleylleyda: Barta dhalaalka sare ee aluminium aluminium gaar ah ayaa ka dhigaysa mid ku habboon isticmaalka kulaylka beddelayaasha, halkaas oo ay u adkeysan karaan heerkulka shaqeynta sare iyada oo aan dhalaalin.
  • Qalabka karinta: Barta dhalaalka sare ee aluminiumku waxay sidoo kale faa'iido u leedahay soo saarista qalabka wax lagu kariyo, hubinta in dheryaha iyo digsiyada ay xamili karaan heerkulka karinta sare iyada oo aan khatar dhalaalid lahayn.

Sidee barta dhalaalaysa aluminium barbardhigaan biraha kale

Marka la barbar dhigo biraha kale, barta dhalaalaysa ee aluminiumku maaha mid sarreeya. Halkan waxaa ah isbarbardhigga dhibcaha dhalaalka aluminiumka iyo biraha kale ee caadiga ah:

Birta Meesha dhalaalaysa (°C) Meesha dhalaalaysa (°F)
Aluminium 660.32 1220.58
Copper 1085 1981
Birta 1538 2800
Zinc 419 776
Birta 1370 – 1520 (kala duwan) 2502 – 2760 (kala duwan)

Isbarbardhiggani wuxuu muujinayaa in aluminiumku leeyahay meel dhalaalaysa oo ka hooseeya biraha sida birta iyo birta, wuu ka sarreeyaa zinc iyo biraha kale oo badan. Tani waxay aluminium ka dhigeysaa meel ku habboon codsiyada u baahan dheelitirka u dhexeeya caabbinta heerkulka sare iyo shaqeynta.

Gabagabadii, barta dhalaalaysa ee aluminiumku waa hanti muhiim ah oo saamaynaysa isticmaalkeeda warshado kala duwan. Fahamka arrimaha saameeya hantidan iyo sida ay u barbar dhigayso biraha kale waxay lama huraan u tahay xulashada agabka iyo hagaajinta habka. Aluminium barta dhalaalka sare, oo lagu daray sifooyinkeeda kale ee faa'iidada leh, waxay ka dhigtaa walxo badan oo kala duwan oo codsiyo ah.
