Koj paub ntau npaum li cas polyurea?
Polyureaa yog ib qho khoom siv elastomeric tsim los ntawm cov tshuaj tiv thaiv ntawm ovocyanate Cheebtsam nrog amine compounds. Nws sawv cev rau ib tiam tshiab ntawm cov txheej txheem phooj ywg zoo, tsim kom tau raws li kev cai ib puag ncig. Ua raws li qhov tshwm sim ntawm tsawg -} {}} Cov xim dej, tsis muaj cov dej ua paug, tsis muaj cov tshuaj tua kab, thiab tsis muaj kuab paug. Nws yog qhov dav tau lees paub tias yog kev sib nrawm nrawm rau hauv kev lag luam txheej. Txawm hais tias muaj kev hloov kho sai heev, ntau ntawm nws cov ntawv thov siab thiab cov ntaub ntawv txheej txheem tseem nyob ntawm theem kev tshawb fawb lossis cov theem tsis pub lwm tus paub.
Kev txhim kho polyurea tau nce los ntawm peb theem loj:
Ntshiab polyurethane (PU)
Polyurethane / Polyurea Hybrid (PU / PUA)
Ntshiab polyurea (pua)
Nyob rau hauv nruab nrab-1980s, lub teb chaws Yelemees ua ntej tsim kev tsuag polyureea elastomer (spua) thev naus laus zis. Ib daim ntawv av luam tawm luam tawm nyob rau hauv 1989 sparked tseem ceeb txaus siab thoob ntiaj teb. Los ntawm 1991, thev naus laus zis nkag mus siv kev lag luam siv hauv North America. Tom qab ob peb tiam kev hloov kho thiab kho kom zoo, Polyurea tau tam sim no tau tsa dav thoob ntiaj teb.
Polyurea paub txog nws cov versatility, nrog cov ntawv tseem ceeb hauv:
Kev ua dej nag
Corrosion tiv thaiv
Puas ua
Sab saum toj kho kom zoo nkauj
Qee qhov nws muaj feem ntau siv xws li:
Pipeline Corrosion tiv thaiv: ib qho ntawm cov chaw ua ntej thiab loj tshaj plaws rau polyurea.
Kev tiv thaiv hlau steel: tshwj xeeb tshaj yog nyob rau hauv ib puag ncig marine li docks thiab steel pilings.
Kev Cuam Tshuam -} Resistant Txheej: Siv rau cov tubrog nkoj buoys, Fenders, thiab elastic sib tsoo cov ntaub ntawv.
Nuclear Fais Fab Cov Chaw: rau kev tiv thaiv sab nrauv thiab khoom siv.
Kev tiv thaiv thiab tub rog: rau tank chassis txheej, baperoproof lub kaus mom, thiab lwm yam.
Ua luam dej pas thiab dej chaw
Kev nthuav dav rau hauv kev siv txim
Nyob rau hauv xyoo tsis ntev los no, Polyurea tau pib tshwm sim nyob rau hauv cov chaw nyob thiab kev ua lag luam. Piv txwv li:
Waterproofing ntawm rooto, phab ntsa, thiab chav dej hauv tsev yuav siv polyurea rau nws cov seamless thiab kev tiv thaiv.
Pobzeb Grout (Seam Filling) cov ntaub ntawv tsim los ntawm peb {-}}} Nplooj Polyurea kuj tseem tau txais cov khw muag khoom. Cov ntaub ntawv no muaj xoom -}}}}}}}}} xyoo ntawm kev ua haujlwm ruaj khov, txhua lub sijhawm ua tau zoo rau kev thov.
Tawm teb: Blast Kuj
Ib qho ntawm cov nrawm tshaj plaws - Kev ntxiv} Kev thov cov chaw rau Polyurea yog Blast - Resistant txheej. Hauv kev teb rau Tuam Tshoj lub teb chaws peb {{{}} kev nrhiav chaw ruaj ntseg thiab cov vaj tse tau txhim kho nrog kev ua kom tawg yooj yim- tsis muaj peev xwm. Cov txheej txheem tshwj xeeb no yuav tsum tau nruj kev qhia txuj ci tshwj xeeb thiab feem ntau kim dua.
Txawm li cas los xij, vim tsis muaj kev paub txog kev lag luam, qee cov neeg yuav khoom tsom rau tus nqi thiab tsis muaj qhov sib tw ntawm txoj kev muaj peev xwm loj heev {}} tiv taus polyurea thiab cov khoom lag luam qis dua. Qee cov neeg xa khoom tsis muaj peev xwm siv polyurea nyob rau hauv qhov chaw muaj ntawv pov thawj los yog muab cov khoom lag luam tsis txaus ntseeg lossis muaj kev nyab xeeb rau cov qauv kev nyab xeeb.
