Aluminiyamu: Properties kunye ngensimbi

Aluminium - ezifuneka kakhulu njengoko metal kolu lwakhiwo, kwakunye nezinye iinkalo zezinto ezenziwa luluntu. Noko ke, ekwimo yayo enyulu asisetyenziswa kunqabile kakhulu. I-aluminiyamu ezininzi ezisetyenziswayo rhoqo.

Zonke aluminiyamu lungahlulwa-hlulwa ibe eyahlulayo wenza. Uhlobo lokuqala yenziwa yi yokunyibilika kunye aluminium Manufacturing uhlobo yesibini ingcinezelo isicelo. Baza, aluminiyamu ngokufuthi thaca aluminiyam compound nge electronic. Ezo iintsimbi eqinile, babe nokumelana eliphezulu, cut elungileyo. Njengoko for ezenziwe aluminiyamu, phakathi kwabo edumileyo na duralumin, apho isakhiwo aluminiyam, nemagnesium nangobhedu. Le wire metal yenziwa, iprofayili, iphepha, iteyiphu. Inkqubo ingxubevange zinganikezelwa nangayiphi indlela.

Iimpawu ze-aluminiyam aluminium lungohlulwa lube emzimbeni, mechanical nemichiza. Ngokubhekiselele kwiipropati emzimbeni, le aluminium kufuneka phantse elifanayo loxinano njengoko i-aluminiyamu ngokwayo. Baye amandla ophezulu, nto leyo ukukhuphisana titanium nensimbi. Kodwa apha kufuneka kuqatshelwe ukuba iqondo lobushushu yokunyibilika iSebe eli ingxubevange incinane (kuba iqondo malunga 200). Kuyaphawuleka ukuba aluminiyamu, babe conductivity elungileyo thermal, ngokuphawulekayo ukuqhuba umbane nge welding kakuhle kwaye ukumelana umhlwa, nangona aluminiyam ecocekileyo, le mihlaba axhome kakhulu.

Ngokubhekisele iimpawu mechanical, baba ephakamileyo ukwandisa degree of kweziyobisi. aluminiyamu thaca asetyenziswa ukwakhiwa kweendlela kulayishwa eliphantsi neliphakathi. Kufuneka kuqatshelwe ukuba iimpawu aluminium zibethwa kwatshintsha emva ubilisa ukuya kwiqondo elithile, nto leyo ebonisa kwaye isebenzisa.

Njengoko ingxubevange phambi kokusebenzisa imfuneko ukusebenza, kwaye ukuba bayile ezithile alloying iziqalelo kufuneka nge welding, kufuneka sinikele ingqalelo into yokuba welding aluminiyamu inemisebenzi ethile. Le nkqubo iye iingxaki ezithile:

- aluminiyamu nzima ofunwa kuba umboniso oxide elivela phezu kwamanzi metal (idla contaminates omhlophe, yaye oku ophazamisa elintlangothi alloying metal oqhelekileyo);

- umboniso oxide kunye ingxubevange ngokwayo kufuneka lokunybilika ezahlukeneyo, umahluko ingaba mibi;

- ukusukela bephosa ulwandiso aluminium phezulu ngokwaneleyo, emva kokuba intsimbi ukuwelda angafaka zikhubazekile;

- aluminiyamu babe ombo, ngoko imisinga ukuwelda esinokubakho intsimbi.

Kuba welding aluminiyamu ikakhulu kusetyenziswa carbon okanye metal electrode. Le nkqubo yenziwa nge current rhoqo wokwephuka esahlukileyo. Phambi kokuqala umsebenzi piece umsebenzi ukuphathwa acetone okanye benzine kunye ibhrashi ngentsimbi ahlambuluke. Ukuze ngcono welding umgangatho sele idlule, kuyimfuneko ukuba ukufudumeza iindawo welding ku lobushushu kwangaphambili (200 degrees). Ukuze ufumane umthungo elungileyo emva iwelding kufuneka lwehle kancinci.
