Lub yeeb nkab steel tau xau thaum lub Plaub Hlis, 2015. Nws nyob hauv Yantai nroog, Shandong xeev. Peb txau peb 100% ntshiab si polyurea khoom rau cov yeeb nkab. Peb cov polyurea ntshiab txheej tau tiav zoo heev corrosion tsis kam, kev tiv thaiv thiab pom tshwm.
Peb Qtech polyurea cov khoom lag luam lojyog tsim los ntawm Qingdao Shamu Advanced Material Co., Ltd. thiab lub koom haum ntawm Chaw Haujlwm Khoom Siv hauv Qingdao University of Technology thiab nws qhov kev ua tau zoo saum toj kawg nkaus hauv Suav teb thiab ua thoob ntiaj teb hauv nws cov qeb zoo sib xws.
Cov Kev Siv Polyurea
Cov ntaub ntawv ntshiab polyurea muaj cov dej tsis zoo, tiv thaiv kev xeb thiab tiv thaiv kev tawm tsam. Cov ntaub ntawv polyurea tsis muaj qhov sib txuam thiab du.
Pure polyurea yog dav siv nyob rau hauv ntau yam ntawm tej yaam num, tshwj xeeb tshaj yog haum rau:
1. Dej tsis ua haujlwm:kev kub ceev hauv kev tsheb ciav hlau, qhov av, chaw ntaus pob ncaws pob, lub ru tsev, chaw nyob hauv av, pas dej, qhov dej txuag txoj haujlwm, thiab lwm yam.
2. Los tiv thaiv corrosion tej yaam num:sab nrauv& cov yeeb nkab sab hauv kab / cia tank, roj xa dej, thiab lwm yam.
3. Ua cov phiaj xwm tiv thaiv:dej num cov dej hiav txwv, kev tsim ua vaj tsev, tsim duab yeeb yaj kiab thiab TV, tsim kev lag luam thiab pej xeem thiab lwm yam.
Polyurea tuaj yeem siv dhau qhov sib txawv ntawm cov khoom sib txawv (pob zeb, hlau, ntoo thiab lwm yam) nyob rau hauv qhov dav ntawm qhov kub thiab cua sov ib puag ncig.Ntxiv rau cov chaw cob qhia cov chaw ruaj khov, cov khoom siv pleev xim tuaj yeem muab tshuaj tsuag rau txhua lub sijhawm, txhua qhov chaw.
Polyurea Cov Nta
1. Kev ua haujlwm siab thiab tua ceev ceev.
2. Tsis rhiab rau qhov kub thiab txias thiab txias, txawm tias tuaj yeem kho nyob rau saum npoo dej thiab dej khov.
3. Cov khoom zoo heev hauv lub cev, xws li kev ua haujlwm siab tuag, siab tensile lub zog, siab elongation, cuam tshuam lub zog thiab lwm yam.
4. Nws tsis muaj ib qho kev hloov pauv ntawm cov organic (VOC), yog tus phooj ywg ib puag ncig, thiab tsis muaj kuab lom, tsis muaj ntxhiab thiab tsis muaj kuab lom.
5. Kev siv tshuaj lom neeg zoo heev thiab kho kom zoo nkauj.
6. Huab cua tiv taus zoo thiab laus ua hauj.
Polyurea Txheej Piav Qhia
Lub polyurea elastomer yog elastomer tsim los ntawm kev ua kom rov tivthaiv A tivthaiv isocyanate nrog B tivthaiv amino xyaw cob. Cov yam ntxwv tseem ceeb tshaj plaws yog los tiv thaiv corrosion, tsis muaj dej thiab hnav-resistant.
Ib qho tshuaj tivthaiv tuaj yeem yog tus ntxhiab isocyanate lossis aliphatic isocyanate. B tivthaiv yog tsim ntawm lub davhlau ya nyob twg amino polyether thiab lub davhlau ya nyob twg amino saw extender.
A / B tivthaiv tshuaj los tsim urea daim ntawv cog lus, thiab cov qauv ntawm urea daim ntawv cog lus yog zoo, nrog rau cov yam ntxwv ruaj khov thiab zoo rau lub zog nyiaj, uas ua rau cov polyurea zoo heev hauv cov yam ntxwv thiab ruaj khov heev.
