SWD900 SPUA amazi meza anticorrosion yamazi adafite amazi ni polymer yakiriwe na Isocyanate (ishyaka A) hamwe n’ikigo cya Amino (ishyaka B).Tekinike ya tekiniki yatumijwe muri Sosiyete ya SWD Urethane, ibikoresho fatizo hamwe nuburyo bwo kubyaza umusaruro byemejwe nta byangiza kandi bifite uburozi, byujuje ibyangombwa bisabwa kugira ngo bisobanurwe ku bicuruzwa by’amazi meza kandi byabonye uruhushya rw’ubuzima rwa Minisiteri y’inganda z’imiti.Igikorwa gikora ni (Jiangsu) amazi yisuku (2016) nimero 3200-0005.Dukurikijeho ibishishwa byinshi, amazi yo mu mazi, imishwarara ishobora gukira, ifu yifu nubundi buryo bwo gukoresha umwanda muke (oya), tekinoroji ya Spray Polyurea Elastomer (ngufi nka SPUA) nubuhanga bushya butarangwamo umwanda, butagira umwanda udafite umwanda. yateye imbere kugirango yuzuze ibisabwa mu myaka hafi makumyabiri mu mahanga.Yakoreshejwe mu miyoboro y'amazi yo kunywa, mu bigega byo kubikamo no mu bigega by’amazi byujuje ubuziranenge bw’ibiribwa, hamwe n’indashyikirwa zidasanzwe zidafite amazi, kurwanya ruswa ndetse n’ubushobozi bwo kurinda, ndetse no kurengera ibidukikije, imikorere y’isuku idafite umwanda.
