I-Polyurea iyi-polymer ephilayo ewukusabela kwe-isocyanate ene-amine enqanyuliwe i-polyether resin, yakhe inhlanganisela efana nepulasitiki noma efana nerabha enolwelwesi olungenamthungo.
I-Polyurea idinga ukuqeqeshwa okukhethekile kanye nemishini yokusetshenziswa kwensimu, kungakhathaliseki ukuthi isetshenziswa njengesigcwalisi esihlanganyelwe noma njengesimbozo esifakwe ensimini.UShundi unohlelo oluqhubekayo lweukuqeqeshwa kosonkontilekaendaweni.Kukhona abafake izicelo abaqeqeshiwe e-China.
Njengomthetho ojwayelekile,Shundii-polyurea ingasetshenziswa ukuqukatha noma iyiphi into engase ikhishelwe ngokuqondile kumasistimu endle ahlanzekile.Ingasetshenziswa kunoma yikuphi ukhonkolo, insimbi, izinkuni, i-fiberglass, izindawo ze-ceramics.
I-Shundi polyureas iqala ukuthuthukisa izakhiwo zayo ezingokomzimba phakathi nemizuzu yokusetshenziswa.I-polyurea ephulukisiwe ingamelana nezinga lokushisa ukusuka ku--40 ℃ ukuya ku-120 ℃, Nakuba i-polyurea inokuguqulwa kwengilazi ephezulu nokushisa kwamazinga okushisa okuchezuka, izovutha lapho ichayeke elangabini eliqondile.Izozicisha uma ilangabi lisuswa.Kodwa futhi sine-polyurea evimbela umlilo ngezimfuneko ezikhethekile ezifana nemigudu yesitimela nezindlela zethrafikhi.
I-Polyurea ingase ibe lukhuni noma ithambe kuye ngokwakhiwa okuthile kanye nokusetshenziswa okuhlosiwe.Izilinganiso ze-Durometer zingasukela ku-Shore A 30 (ezithambile kakhulu) ziye ku-Shore D 80 (okunzima kakhulu).
Empeleni kunezinhlobo ezimbili ezahlukene zezinhlelo ze-aliphatic polyurea ezisemakethe njengamanje.Olunye uhlelo olujwayelekile lokufafazwa komfutho ophezulu/izinga lokushisa kanti elinye yilokho okwaziwa ngokuthi uhlelo lohlobo lwe-“polyaspartic polyurea”.Lolu hlelo lwe-polyaspartic luhlukile ngoba lusebenzisa ingxenye ye-ester-based resin futhi lunempilo ende yebhodwe.Ingasetshenziswa ngesandla kusetshenziswa ama-roller;amabhulashi;ama-rakes noma izifutho ezingenawo umoya.Amasistimu we-aspartic awawona ama-high build coating afana nezinhlelo ze-polyurea "hot spray".Amasistimu we-polyurea anuka kamnandi kufanele acutshungulwe ngomfutho ophezulu, amaphampu engxenye yobuningi ashisiwe futhi afuthwe ngesibhamu sohlobo lwe-mpingement.Lokhu kuyiqiniso futhi ngenguqulo ye-aliphatic yalolu hlobo lwesistimu, umehluko oyinhloko ukuqina kombala wezinhlelo ze-aliphatic.
Umkhiqizo ngamunye kuwebhusayithi yethu unamashadi Okumelana Nemakhemikhali ngaphansi kwethebhu ethi Amadokhumenti.
Elinye lamahhashi ethu okusebenza uma kukhulunywa ngokuchayeka kwamakhemikhali okunonya kakhulu yi-SWD959Ngaphezu kwalokho, uma unekhemikhali ethile obhekene nayo (noma uhlelo oluthile), zizwe ukhululekileXhumana nathingakho-ke singakusiza ukuthi unqume uhlelo olungcono kakhulu lwezidingo zakho.
Sinembobo ye-urethane yokwelapha umswakama kanye nenamathela eqinile ye-polyaspartic enokusebenza okuphezulu kokumelana namakhemikhali kuzincibilikisi, ama-acids noma ezinye izincibilikisi.Ingakwazi ukumelana no-50% H2SO4kanye ne-15% HCL.
Incike ekubunjweni kwayo, nakuba ekwakhiweni okuthile kuka-Shundi, i-polyurea ngeke inciphe ngemva kokuba selashiwe.
Nokho, lona umbuzo omuhle ongawubuza kunoma ubani okhetha ukuthenga kuye izinto ezibonakalayo - ingabe impahla yakho iyashwabana noma cha?
Sinomkhiqizo ophelele walolu hlobo lwesicelo, i-SWD9005, Lo mkhiqizo uhlolwe kakhulu embonini yezimayini, futhi uye wenza ngokungaguquki ngaphezu kwalokho obekulindelwe.
Ngokucwiliswa emanzini / izinhlelo zokusebenza zensimbi, khumbula ukuthi i-PUA (i-polyureas) ne-epoxy akufani.Zombili ziyizincazelo zobuchwepheshe / zohlobo lomkhiqizo.Amasistimu e-PUA asebenza kahle ekucwilisweni, kodwa kufanele akhiwe ngendlela efanele lolo hlelo lokusebenza.
Nakuba amasistimu e-epoxy eqinile kakhulu, amasistimu e-PUA anokuguquguquka okuphakeme kanye namazinga aphansi okungena kumasistimu akhiwe kahle.I-PUA iphinde ibe yinto esheshayo yokubuyela emsebenzini ngokuvamile - i-polyurea yelapheka phakathi namahora uma kuqhathaniswa nezinsuku (noma ngezinye izikhathi amasonto) kuma-epoxies.Kodwa-ke, inkinga enkulu ngalolu hlobo lomsebenzi kanye nama-substrates ensimbi ukuthi ukulungiswa kwendawo kubalulekile.Lokhu KUMELE kwenziwe ngendlela efanele/ ngokuphelele.Yilapho iningi libe nezinkinga lapho lizama lolu hlobo lwamaphrojekthi.
Bheka wethuIsiceloamacala amakhasiamaphrofayili kulokhu nezinye izinhlobo eziningi zezinhlelo zokusebenza.
Ngokuvamile, upende wendlu we-acrylic latex wekhwalithi enhle ongu-100% usebenza kahle phezu kwe-polyurea efuthiwe.Ngokuvamile kungcono kakhulu ukumboza i-polyurea (ngokushesha kunokuba kamuva) phakathi namahora angu-24 wokufaka isicelo.Lokhu kukhuthaza ukunamathela okuhle kakhulu.I-Polyaspartic UV resistance topcoat iyanconywa ukuthi isetshenziswe ngaphezu kwe-polyurea ukuze ivimbele ukuguga kangcono kanye nokumelana nesimo sezulu.
