I-polyurea iwuhlobo lwesifutho esigcotshwayo esisetshenziswa njengoketshezi futhi lwelaphe ngokushesha esimweni esiqinile.Yenziwe ngenhlanganisela ye-polyurethane ne-isocyanate, esabelana nomunye nomunye ukwakha ifilimu eqinile, eqinile.Izembatho ze-polyurea zaziwa ngezici zazo zokusebenza okuphezulu, okuhlanganisa ukuhuzuka okuhle kakhulu nokumelana namakhemikhali, amandla okushuba okuphezulu, kanye nesikhathi sokwelapha ngokushesha.
Izembatho ze-polyurea zivame ukusetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi ezokwakha, ezezimoto, nezolwandle.Zingasetshenziswa endaweni ebanzi, okuhlanganisa ukhonkolo, ukhuni, insimbi, nokunye.Inqubo yokufaka isifutho ivumela ukuthi kusetshenziswe ungqimba oluncane, ngisho nolwelwesi lwe-coating, olungase lube nenzuzo ekufinyeleleni isiphetho esibushelelezi, esichwepheshile.Izembatho ze-polyurea zivame ukusetshenziswa njengezingubo zokuzivikela, izintambo zombhede wamaloli, okokuvikela ukugqwala, okokuvikela amanzi, kanye nephansi lezimboni nezentengiso.
I-polyurea ihlala isikhathi esingakanani?
Ukuphila kwe-polyurea enamathela kuzoncika ezintweni ezihlukahlukene, okuhlanganisa ukushuba kwe-coating, uhlobo lwe-polyurea esetshenzisiwe, nezimo lapho kuvezwa khona.Ngokuvamile, izigqoko ze-polyurea ziyaziwa ngokuqina kwazo okuhlala isikhathi eside futhi zingahlala iminyaka eminingi ngokulungiswa okufanele.Ezinye izimbotshana ze-polyurea zenzelwe ukusebenza isikhathi eside futhi zingahlala amashumi eminyaka.
Kodwa-ke, kubalulekile ukuqaphela ukuthi akukho ukunamathela okungabhubhiki ngokuphelele futhi zonke izigqoko zizogcina zidilike ngokuhamba kwesikhathi.Ubude besikhathi lapho i-polyurea enamathelayo izothatha isikhathi esingakanani buzoncika ezimweni ezithile lapho i-polyurea ichayeka khona, njengenani lethrafikhi noma ukuguga nokuklebhuka kwayo, ukuba khona kwamakhemikhali noma izici zemvelo ezingase zehlise isithunzi se-coating, kanye izinga lesondlo eliyitholayo.Ukuhlola nokugcinwa njalo kungasiza ekweluleni isikhathi se-polyurea coating nokuqinisekisa ukuthi iyaqhubeka nokuhlinzeka ngokusebenza kahle.
Ingabe i-polyurea inamathela emanzini?
Yebo, i-polyurea coatings iyaziwa ngezindawo zayo ezinhle kakhulu zokuvimbela amanzi.Uma isetshenziswa endaweni engaphezulu, i-polyurea yenza isendlalelo esiqhubekayo, esingenamthungo esimelana kakhulu nokungenwa kwamanzi.Ivame ukusetshenziswa njengendlela yokuvikela amanzi ophahleni, izisekelo, nezinye izindawo ezivezwe emanzini.
Ngaphezu kwamakhono ayo okuvimbela amanzi, izimbotshana ze-polyurea ziyaziwa futhi ngokumelana kwazo namakhemikhali okuhle kakhulu kanye nekhono lokumelana nezindawo ezinokhahlo.Lezi zici, kanye nesikhathi sakhona sokwelapha ngokushesha kanye nekhono lokufafazwa endaweni ehlukahlukene, kuyenza ibe ukukhetha okudumile ekuvimbeleni amanzi kanye nezinye izinhlelo zokusebenza zokuhlanganisa ezivikelayo.
Ingabe i-polyurea coating iyashelela?
Ukumelana nokushelela kwe-polyurea coating kuzoncika ekwakhiweni okuqondile kanye nendawo esetshenziswa kuyo.Ezinye izimbotshana ze-polyurea zenziwe ngokuqedwa okumahhadlahhadla noma okuthungwe ukuze kuthuthukiswe ukumelana nokushelela, kuyilapho ezinye zibushelelezi futhi zishelela kakhulu.Ngokuvamile, izimbobo ze-polyurea azikwazi ukumelana nokushelela njengezinye izinhlobo zokumboza, njenge-epoxy noma i-rubber-based coatings.
Uma ukuphikiswa kokushelela kuwukukhathazeka, kungase kusize ukukhetha i-polyurea ehlanganiswe ngokukhethekile ukuze kuthuthukiswe ukumelana nokushelela noma ukwengeza isithasiselo esingasheleli embotsheni ngaphambi kokuba sisetshenziswe.Kubalulekile futhi ukucabangela indawo okuzofakwa kuyo ukunameka, njengoba ezinye izindawo ngokwemvelo zishelela kakhulu kunezinye.Isibonelo, iphansi likakhonkolo elibushelelezi lingase lishelele kunendawo emagebhugebhu noma enezimbotshana.
