Tus ntshiab polyurea choj kev tiv thaiv kev tsim kho tau raug txau thaum Lub Xya Hli, 2013. Nws nyob hauv Qingdao nroog, Shandong xeev thiab thaj chaw tsuag tag nrho yog 2800 square meters. Peb tau txau peb cov khoom Qtech-401 polyurea rau cov khoom siv ua haujlwm tiv thaiv kev tiv thaiv. Peb cov polyurea ntshiab txheej tau tiav zoo heev corrosion tsis kam, abrasion tsis kam thiab cov dej tsis qab.
Cov txheej txheem kev tsim kho yog ua raws:
1. Sandinglub substrate.
2. Sau qhov tawg nrog polyurea sib xyaw ua ke.
3. Primer daim ntawv thov.
4. Txau cov tshuaj ntshiab polyurea.
Cov ntaub ntawv ntshiab polyurea muaj kev tiv thaiv zoo, tiv thaiv kev nplua, los tiv thaiv kev pom thiab hnav tsis kam. Nws tuaj yeem siv dav hauv kev tiv thaiv cov pob zeb ua kev tsheb nqaj hlau ntawm kev kub ceev, kev tiv thaiv tus choj hla ntawm tus choj hla hiav txwv, kev tiv thaiv sab hauv phab ntsa ntawm subsea qhov, kev tiv thaiv dej ntawm nroog subway, waterproof ntawm ru tsev ntawm qib siab lub tsev, tiv thaiv corrosion ntawm pob zeb sawv ntawm chaw ntau pob, chaw tsim tshuaj, nkoj lawj, ntug dej hiav txwv drilling platform thiab lwm cov teb.
