Kugwiritsa ntchito ma alloys apadera m'munda wochotsa madzi am'nyanja:
Zida ndi zida zomwe zimagwiritsidwa ntchito pochotsa mchere m'madzi a m'nyanja ziyenera kukhala ndi mikhalidwe yolimbana ndi dzimbiri, ndipo kusankha ndi kupanga mfundo za zinthuzo zimadalira malo ogwirira ntchito azinthuzo. Chitsulo chosapanga dzimbiri chakhala chinthu choyenera chifukwa cha kukana kwa dzimbiri komanso kulimba kwake, ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana zochotsa mchere.
Chifukwa madzi a m'nyanja amakhala ndi zinthu zambiri zowononga, ndipo chipolopolo, mpope wamadzi, evaporator ndi payipi yotentha kwambiri yofunikira popanga zida zamadzi a m'nyanja ndi mbali zonse zomwe zimalumikizana mwachindunji ndi madzi am'nyanja, ndipo ziyenera kukhala ndi dzimbiri lamphamvu. kukana, kotero onse mpweya zitsulo si oyenera ntchito. Komabe, chitsulo chosapanga dzimbiri cha super austenitic, chitsulo chosapanga dzimbiri cha duplex ndi titaniyamu yozizira yozungulira imakhala ndi kukana dzimbiri kwamadzi a m'nyanja, zomwe zimatha kukwaniritsa uinjiniya wochotsa mchere m'madzi a m'nyanja, ndipo ndi zida zabwino zopangira distillation zamitundu yambiri ndikusinthanso zomera za osmosis desalination.
Zida zapadera za alloy zomwe zimagwiritsidwa ntchito pochotsa madzi am'nyanja:
Chitsulo chosapanga dzimbiri: 317L, 1.4529, 254SMO, 904L, AL-6XN, etc.
Nickel base alloy: Aloyi 31, Aloyi 926, Inkoloy 926, Inoloy 825, Monel 400, etc.
Aloyi yolimbana ndi dzimbiri: Inkoloy 800H
