Profile aluminiumku wuxuu leeyahay codsiyo kala duwan oo kala duwan, laakiin sababtoo ah kala duwanaanta kala duwan ee aluminiumka, way adkaan doontaa in la xakameeyo dhamaystirka habka extrusion, sidaas darteed waxay keeni doontaa dulness, iyada oo loo marayo cilmi baaris dhalaalka alaabta aluminiumka ah waxaa lagu hagaajin karaa saddex dhinac:
1. Isku-dhafka Alloy ee walxaha: kordhinta maadada kiimikada ee copper iyo magnesium, saamiga lagu taliyey waa: Si0.55-0.65, Fe<0.17, Cu0.3-0.35, Mg1.0-1.1.
2. Xakamee habka extrusion iyo hagaajinta heerkulka ka soo baxa extrusion profile aluminium. Waxaa lagu talinayaa in heerkulka usha aluminium ah 510-530 ℃ iyo heerkulka outlet 530-550 ℃.
3. Beddel habka pretreatment ee midabaynta oxidation anodic, kaliya pickling saliid for profiles aluminium, ma daxalka alkali.
Fikir:
Daahan aluminium profile hadda waa guud ahaan daahan budo iyo daahan rinjiga.
Si loo helo iftiin iyo saamayn dhalaalaysa:
1. Isticmaal qori buufin fiican ah, iyo inta badan tirada budada xabka budada ah, way sii weyn tahay ceeryaamo ayaa ka sii wanaagsan
2. dhalaal sare leh (gloss 95 iyo wixii ka sareeya) budo (midab ikhtiyaari ah) ama rinji leh rinji fluorocarbon wanaagsan
