Polyurea ni polymer kama nigisubizo cya isocyanate hamwe na amine yarangiye polyether resin, ikora plastike isa na plastike cyangwa reberi isa na membrane idafite icyerekezo.
Polyurea isaba amahugurwa yihariye nibikoresho byo murimurima, yaba ikoreshwa nkuzuza hamwe cyangwa nkumurima washyizweho.Shundi ifite gahunda ihoraho yaamahugurwa ya rwiyemezamirimomu mwanya.Hariho abasaba babishoboye mubushinwa.
Nkibisanzwe,Shundipolyurea irashobora gukoreshwa kugirango ibemo ibintu byose bishobora guhita bisohoka muri sisitemu isanzwe.Irashobora gukoreshwa kubintu byose bifatika, ibyuma, ibiti, fiberglass, ceramics.
Shundi polyureas itangira guteza imbere imiterere yumubiri muminota mike yo gusaba.Polyurea ikize irashobora kurwanya ubushyuhe kuva kuri -40 ℃ kugeza kuri 120 ℃, Mugihe polyurea ifite ikirahure kinini hamwe nubushyuhe bwubushyuhe bwo guhindagurika, izashya iyo ihuye numuriro utaziguye.Bizizimya iyo flame ikuweho.Ariko dufite kandi polyurea-idashobora kuzimya umuriro kubisabwa bidasanzwe nka metero ya metero ninzira nyabagendwa.
Polyurea irashobora kuba ikomeye cyangwa yoroshye bitewe nuburyo bwihariye nuburyo bukoreshwa.Ibipimo bya Durometero birashobora kuva kuri Shore A 30 (byoroshye cyane) kugeza kuri Shore D 80 (birakomeye).
Mubyukuri hariho ubwoko bubiri butandukanye bwa sisitemu ya alifatique polyurea kurubu ku isoko.Imwe ni uburyo busanzwe bwumuvuduko mwinshi / ubushyuhe bwatewe sisitemu naho ubundi nicyo kizwi nka sisitemu ya "polyaspartic polyurea".Sisitemu ya polyaspartic iratandukanye kuberako ikoresha ester ishingiye kuri resin kandi ifite ubuzima burebure.Irashobora gukoreshwa intoki ukoresheje umuzingo;brushes;rake cyangwa niyo spray idafite umuyaga.Sisitemu ya aspartic ntabwo yubatswe hejuru yububiko bwa sisitemu ya "hot spray" polyurea.Sisitemu isanzwe ya aromatic polyurea igomba gutunganywa binyuze mumuvuduko mwinshi, gushyushya pompe yibice byinshi hanyuma bigaterwa muburyo bwa spray-gun.Ibi nukuri kandi kuri alifatique verisiyo yubu bwoko bwa sisitemu, itandukaniro ryibanze ni ibara ryimiterere ya sisitemu ya alifatique.
Buri gicuruzwa kurubuga rwacu gifite imbonerahamwe ya Chemical Resistance munsi ya tab.
Imwe mumafarasi yacu yo gukora iyo igeze kumiti ikaze cyane ni SWD959Byongeye kandi, niba ufite imiti yihariye urimo ukorana (cyangwa porogaramu yihariye), umva nezatwandikireturashobora rero kugufasha kumenya sisitemu nziza kubyo ukeneye.
Dufite ibishishwa bivura urethane hamwe na polyaspartic igoye ifite imikorere myinshi yo kurwanya imiti kumashanyarazi, acide cyangwa indi myanda.Irashobora kurwanya 50% H.2SO4na 15% HCL.
Biterwa nuburyo, nubwo muburyo bwihariye bwa Shundi, polyurea ntizagabanuka nyuma yo gukira.
Ariko, iki nikibazo cyiza cyo kubaza umuntu wese wahisemo kugura ibikoresho - ibikoresho byawe biragabanuka cyangwa ntibigabanuka?
Dufite ibicuruzwa byiza kuri ubu bwoko bwa porogaramu, SWD9005, Iki gicuruzwa cyageragejwe cyane mu bucukuzi bw'amabuye y'agaciro, kandi buri gihe cyakoze hejuru y'ibiteganijwe.
Kubijyanye no kwibiza / ibyuma, uzirikane ko PUA (polyureas) na epoxy bidasa.Byombi nibisobanuro byikoranabuhanga / ubwoko bwibicuruzwa.Sisitemu ya PUA ikora neza yo kwibiza, ariko igomba gutegurwa neza kubyo gusaba.
Mugihe sisitemu ya epoxy irakomeye cyane, sisitemu ya PUA ifite imiterere ihindagurika kandi igipimo gito cyo kwinjiza sisitemu yateguwe neza.PUA nayo yihuta cyane kugaruka kumurimo muri rusange - polyurea ikiza mumasaha ugereranije niminsi (cyangwa rimwe na rimwe ibyumweru) kuri epoxies.Nyamara, ikibazo kinini hamwe nubu bwoko bwimirimo nicyuma cyubutaka ni uko gutegura hejuru ari ngombwa.BIGOMBA gukorwa neza / byuzuye.Aha niho benshi bagize ibibazo mugihe bagerageza ubu bwoko bwimishinga.
Reba ibyacuGusabaimpapurokumwirondoro kuriyi nubundi bwoko bwinshi bwa porogaramu.
Mubisanzwe, ubuziranenge bwiza 100% acrylic latex inzu irangi ikora neza hejuru ya polyureya yatewe.Mubisanzwe nibyiza gutwikira polyurea (vuba na bwangu) mugihe cyamasaha 24 yo gusaba.Ibi biteza imbere neza.Polyaspartic uv resistance topcoat irasabwa gukoresha hejuru ya polyurea kugirango irwanye gusaza no kurwanya ikirere.
