Ingcaciso yeMveliso
I-Polyurea yinxalenye esetyenziswa kakhulu esetyenziswe ngempumelelo kwiitanki zokugcina izinto ezithintela ukubola, ukuthintela ukungenwa kwamanzi kwizakhiwo zekhonkrithi ezifana neendawo zokupaka, amachibi, kunye neetonela, kunye nezihlanganisi ezidibeneyo okanye izitywini.
- Uluhlu olude lwezinto lungadweliswa njengezo zisetyenziswa njengeengubo ezingangeni manzi. Kangangeenkulungwane ezininzi, ukhetho olulodwa olufumanekayo yayiziimveliso ezisekwe kwi-asphalt. Kwinkulungwane yama-20, kwaveliswa ezinye izinto ezininzi, kuquka i-epoxy kunye ne-vinyl ester.
- I-Polyurea yeyona teknoloji yamva nje yokugquma. Le nto, eyenzelwe imboni yeemoto ngasekupheleni kweminyaka yoo-1980, ngoku isetyenziswa kakhulu kwiinkalo ezahlukeneyo. Ngenxa yokunyanga kwayo ngokukhawuleza, ukumelana nokugqwala, kunye nokumelana nokuguguleka, yenze inkqubela phambili enkulu kubunjineli bokuthintela ukungenwa kwamanzi kwiminyaka eli-10 edlulileyo.
- Xa kwaveliswa i-polyurea, kwakulindelwe ukuba izinto ze-polyurethane zibe buthathaka kakhulu emanzini. Ngokutshintsha amaqela e-carboxyl kwi-polyurethane ngamaqela e-amino, imveliso esiyibiza ngokuba yi-polyurea ngoku yafunyanwa. Le mveliso ayibuthathaka kakhulu emanzini kunezinye iingubo ezisekelwe kwi-polyurethane.
- I-Polyurea ineentlobo ezimbini ezifanayo. I-Aromatic polyurea isetyenziswa rhoqo. Ukusebenza kwale mveliso kunokwahluka kakhulu, ngaloo ndlela inezicelo ezininzi ezahlukeneyo. Enyanisweni, ingxaki kuphela yale ngubo kukungaqini kakuhle kwe-UV. Olunye uhlobo yi-aliphatic polyurea. Ngokusebenzisa iindlela ezahlukeneyo zeekhemikhali ukuyenza ibe nozinzo olungcono lwe-UV, isohlwayo sexabiso siyahlawulwa. Ixabiso lale polyurea lidla ngokuphindwe kabini kune-aromatic polyurea.
Iimpawu zemveliso
Iingubo zePolyurea, njengohlobo olutsha lwengubo esebenza kakhulu, zineempawu ezininzi eziphawulekayo.
- Ineempawu ezintle kakhulu zomzimba, ezifana nokumelana nokuguguleka, okuvumela ukuba i-coating ihlale isemgangathweni kwaye ikhuseleke ixesha elide nakwiindawo ezihlala zingqubana kwaye ziguguleka;
- Kwangaxeshanye, inokumelana okubalaseleyo kwempembelelo, ixhathisa ngempumelelo amandla empembelelo yangaphandle kwaye ikhusela umphezulu wento egqunywe ngengubo ekonakaleni.
- Ngokuphathelele iimpawu zeekhemikhali, ii-polyurea coating zibonisa ukumelana nokugqwala okugqwesileyo. Nokuba zijongene nokukhukuliseka kwee-asidi, ii-alkali, okanye kwiindawo ezinzima zeekhemikhali ezifana nokufuma okuphezulu kunye ne-spray yetyuwa eninzi, zinokuhlala zizinzile ixesha elide kwaye azinakwenzeka kwiimpendulo zeekhemikhali ezibangela umonakalo kwi-coating.
- Ngaphezu koko, inokumelana kakuhle nemozulu, igcina uzinzo lwayo lokusebenza kwiimeko ezahlukeneyo zemozulu, ezifana namaqondo obushushu aphezulu, amaqondo obushushu aphantsi, kunye nemisebe ye-ultraviolet, ngaphandle kokufumana iingxaki ezifana nokuguguleka, ukutshintsha kombala, okanye ukuxobuka ngenxa yotshintsho lwemozulu. Isantya sokuphiliswa kweengubo ze-polyurea sikhawuleza kakhulu, nto leyo ephucula kakhulu ukusebenza kakuhle kokwakhiwa kwaye yenza ukuba ingubo igqitywe kwaye isetyenziswe kwixesha elifutshane.
- Ngaphezu koko, inamathele kakuhle kwiindawo ezahlukeneyo, ikwazi ukunamathela ngokuqinileyo kwiindawo zesinyithi, ikhonkrithi, umthi, njl.njl., nto leyo eyenza umaleko okhuselayo oqinileyo nozinzileyo.
IINGCEBISO ZEMVELISO
- Esinye sezizathu zokuba iingubo ze-polyurea zifumane udumo ngokukhawuleza luluhlu olubanzi lweempawu zazo ezintle kakhulu. Iwebhusayithi yePolyurea.com ithi ngokuphandle ukuba ngokweempawu ezibonakalayo ezikhoyo, akukho lunye uphahla emhlabeni olunokulingana ne-polyurea. Ngokulungisa ifomula, iimveliso ze-polyurea zinokuba noluhlu olubanzi kakhulu lweempawu, ukusuka ekuphakameni okuphezulu ukuya kumandla okuxinana agqwesileyo, kodwa oku kunxulumene nefomula yento kunye nokusetyenziswa ngokuchanekileyo. I-Polyurea inamathele kakuhle kwiindawo ezahlukeneyo kubandakanya ikhonkrithi, isinyithi, kunye nomthi, nokuba ingenaso iprimer, kwaye ingasetyenziswa kwiindawo ezinotshintsho olukhulu lobushushu kunye nokufuma. Mhlawumbi eyona nzuzo imangalisayo ye-polyurea kukuqiniswa kwayo ngokukhawuleza kakhulu. Nje ukuba isetyenziswe, i-polyurea inokufikelela kubukhulu obufunekayo kwingubo enye, ekhawuleza kaninzi kunokusebenzisa iingubo zendabuko, okuvumela umnini ukuba aqalise ukusebenzisa indawo kwaye anciphise ilahleko ngenxa yokungasebenzi.
- Ubukhulu bokusetyenziswa kanye kweengubo ze-polyurea bunokwahluka ukusuka kwi-0.5mm ukuya kwi-12.7mm, kwaye ixesha lokunyanga liqala kwangoko ukuya kwimizuzu emi-2, nto leyo enceda ekufikeleleni ngokukhawuleza kwimeko yokusebenziseka.
- Njengengubo yefilimu etyebileyo ephiliswa ngokukhawuleza, xa kufuneka ukuvalwa kwamanzi kwe-membrane okungenamthungo nokuhlala ixesha elide, i-polyurea lukhetho olufanelekileyo. Ezinye iimpawu, ezinje ngokufuna ukungatyibiliki kunye nokuthungwa komphezulu, zinokufezekiswa ngeendlela ezithile. Ingubo ingapeyintwa kwaye ingasetyenziswa nakwiindawo ezihlangabezana neemfuno zamanzi okusela.
- Ngenxa yoluhlu olubanzi lweempawu zayo zokusebenza, i-polyurea inoluhlu olubanzi kakhulu lwezicelo. Ulwelo lwangaphakathi lweetanki zokugcina, iileya zokhuselo zesibini, kunye nokukhuselwa komphezulu weebhulorho zezona zihlandlo zisetyenziswa kakhulu kolu hlobo lwezinto. Enyanisweni, amathuba okusetyenziswa kwe-polyurea phantse awanamda.
- Iitanki zezityalo zokunyanga amanzi amdaka zihlala zinengxaki ye-vortex, i-scouring, kunye negesi eninzi ye-hydrogen sulfide ngexesha lokuhluza, ukuxuba, kunye neenkqubo zokuphelelwa ngamanzi emzimbeni. Ukusebenzisa i-polyurea kunokubonelela ngokuchasana nokuguguleka okufunekayo, ukumelana neekhemikhali, kunye nokumelana nempembelelo, kwaye kunokubuyisela umzi-mveliso ngokukhawuleza ekusebenzeni, okukhawulezayo kakhulu kunezinye iindlela ezininzi.
- Xa isetyenziswa kwiibhulorho nakwezinye iindawo ezichaphazeleka kukungcangcazela nokushukuma, ukuguquguquka okungokwemvelo kwe-polyurea yenye inzuzo ngaphezu kwezo ngubo zincinci nezingenakuguquguquka njenge-epoxy.
Ukunqongophala kweMveliso
- Kakade ke, i-polyurea ikwanazo nezinye iingxaki. Izixhobo ezifunekayo xa kusetyenziswa i-polyurea coating zibiza kakhulu, ukusuka kwi-$15,000 ukuya kwi-$50,000 nangaphezulu. Iqonga lokwakha elihambayo elixhotyiswe ngokupheleleyo lingabiza ukuya kuthi ga kwi-$100,000.
- Ixabiso lezinto ze-polyurea liphezulu kunelezinye izinto zokugquma. Ixabiso lokuqala liphezulu kunele-epoxy. Nangona kunjalo, ekubeni ubomi benkonzo ye-polyurea coating buphindwe kathathu ukuya kahlanu kunezinye iimveliso, ukusebenza kakuhle kweendleko ngexesha lenkonzo kusenezibonelelo.
- Njengayo nayiphi na enye into yokuthintela amanzi, ukwakhiwa okungafanelekanga nako kunokukhokelela ekusileleni kokusetyenziswa. Nangona kunjalo, iimfuno zokwakha ngeengubo ze-polyurea ziphezulu kakhulu. Unyango lomphezulu olufana nokuqhumisa isanti okanye ukugalela ipriming lubaluleke kakhulu kwi-polyurea. Uninzi lweeprojekthi zokugquma ze-polyurea ezingasebenziyo azinanto yakwenza ne-polyurea ngokwayo, kodwa zibangelwa kukuphathwa komphezulu okungafanelekanga okanye okubi.
Ulwakhiwo
- Uninzi lwe-polyurea esetyenziselwa ukuthintela amanzi yakhiwe kusetyenziswa izixhobo zokutshiza ezinamacandelo amaninzi. Ngokwesiqhelo, kusetyenziswa inkqubo enamacandelo amabini, apho umxube we-amino resin kunye nezinto ze-isocyanate zigcinwe ngokwahlukeneyo kwizikhongozeli ezingama-50-gallon. Ngexesha lokwakhiwa kwindawo yokusebenza, umxholo ovela kwizikhongozeli ezingama-50-gallon udluliselwa kwitanki yesixhobo sokutshiza kwaye ufudunyezwe kubushushu obufanelekileyo (60-71°C). Emva koko, i-isocyanate kunye ne-polyol resin zithunyelwa ngepayipi eshushu ukuya kwi-spray gun.
- Umlinganiselo wezinto ezimbini ulawulwa ngokungqongqo, ngesiqhelo kwi-1:1 ratio.
- Ixesha lokunyanga le-polyurea lilinganiswa ngemizuzwana, ngoko ke la makhemikhali anokuxutywa kuphela kwangoko xa ephuma kwi-spray gun; kungenjalo, aya kunyangeka aze aqine kwi-spray gun.
- Abanye abavelisi bathengisa iiyunithi zokutshiza eziphathwayo, kuquka zonke izixhobo nezixhobo, ezifakwe kwiitreyila okanye kwiibhedi zelori.
