Why amapanga aluminiyumu alloy ogulidwanso ali ndi nkhungu ndi mawanga atasungidwa kwakanthawi?

Vutoli lakumana ndi makasitomala ambiri, ndipo ndizosavuta kwa makasitomala osadziwa kukumana ndi zochitika zotere. Pofuna kupewa mavuto amenewa, m'pofunika kulabadira mfundo zitatu zotsatirazi:

1. Malo omwe zida zimayikidwa sayenera kunyowa. Makasitomala ena amagula zinthu ndikuziyika pansi pazitsulo zachitsulo, zomwe zimatha kutsitsa mvula kapena pansi ponyowa. Ngati atasiyidwa kwa nthawi yayitali, mawanga a nkhungu ndi okosijeni amatha kupanga.

2. Kwa makasitomala a mitundu yokonza, monga kupanga nkhungu, makina, kudula, etc., tcheru chiyenera kulipidwa ngati pali zotsalira zotulutsa zotsalira, kudula madzi, saponification zamadzimadzi, ndi zina zotero. Zinthu zowonongazi ziyenera kuyeretsedwa munthawi yake. Pambuyo pokonza zinthu, ziyeneransokusungidwa bwino. PolSera, madontho amafuta, ndi zina zotere zomwe zimagwiritsidwa ntchito popukuta ziyenera kutsukidwa. Ngati sanasamalidwe bwino, zimakhalanso zosavuta kuyambitsa mawanga achikasu pamtunda wa zinthu panthawi ya anodizing wotsatira.

3. Zolakwika zoyeretsera zomwe zimagwiritsidwa ntchito pazokha zimatha kuyambitsa dzimbiri ndi okosijeni wa zinthuzo.
