Lemali engavalekanga phakathi kwesikhashana sokuqala esingasetyenziswa ngayo ngalowo lwesikhashana isicatshulwa se-Isocyanate Polyurethane. Isiphumo sokuqala sokuthi lento yonke ingu-Isocyanate kunye nepolyol. Ukugcina lezi zimbini zikhetho ukulinganiswa nokuba kufuneka ukufika kwiichemical reaction elinganayo ukuba kuhlonishwe ukuba yindlela eyahlukileyo kunye neyinto yokulungileyo. Uyacombisiwe ukubona ngokubanzi ukuba isicatshulwa se-Isocyanate ipolyurethane yamaphu zokungqinisekisa nokuba ngaphi kuya kwenzekele kwindawo yakho yokugcina kwindawo
Isocyanate polyurethane: Igama lento lengeziwe ngokushaya, inyanga elonakalisiyo lokuphela kunye nezilungu zokugqibela ezizokwenzeka ukuba zivumelwe kwindawo yokulula emfazweni. Ama-isocyanate ni amaxesha omkhulu othile okuthiwa ngokubanzi kwi-english literature. Amasisitayente apha amakhemikali amanani akukho nokuthiwa ngezinye izinto ze-polyurethane (kunye ne-polyols, okuyinoma ezifana ne-oxygen kunye ne-hydrogen). Lapho zingabhalwa phezulu, ama-isocyanates kunye ne-polyols zingezise ukuhlawulwa kwamakhemikali wakugcwaliswa njengoko zisetyenziswa ngokubanzi, uzoba amasandla amadala amahlelo, amaphandle kwezinto ezininzi ezinamandla ezinamandla, ezithiwa amapolimeri. Polyurethane: Amapolimeri amathathu umlando wezinto eziphakeme kunye nokuhlola okanye ekuvumeleni okufanelelwa kwiimbizo yamanje.
Isocyanate ifomu yesi polyurethane esikhulu uyahlukile kunye nesetyenziso, futhi ungene kumane eziphakamisayo ezifanekisa. Kwesibhedlela, usebenziswe ukuba uhlale ukusetha umthwalo wemikhakha, iindlebe nezipayiphi zokuphucuka isithoba lokuhlala ngaphandle komkhulu phambi komnyaka wewinter kunye nokuhlatywa kwindawo yokuhlala ngaphandle komncane phambi komnyaka yesummer. Kwesiseko sesicathulo, usebenziswe ukusetshenziswa amaxwebhu omphambili njengebomvu, amashezi kunye nezindlu zokugcina ezinceda izandla zoceda ukuba zingene ngendlela esenza amacar yasekupheleni kunye nokulula ukusetyenziswa. Kwesiseko sesixhumanisi, usebenziswa ukusetshenziswa amaxesha amancane kunye nokuhlola amacheyi nezindlu zakusebenza ezixinqwangelini zonke elizityenziswa kuleso sikhathi. Isocyanate polyurethane usebenziswayo ngamanye amane akhona ukusetshenziswa amagama, futhi uhlelo lwakho olunqwenene ulungiselela uphawu lwakhe lokusetshenziswa kumane emigca!
Isisophani polyurethane amaphu zokungqinisekisa ngemva kokuba yinto elunyelekileyo, kufuneka kuhlinzekiswe ngokuphathelwayo xa kunyuthelwa. Ukuba akubhekiswanga ngokukhothaniswa, i-isocyanates zizibuzise izandla nokuba ziziphumelele ukusuka komphumende. Ngoko ke kufuneka kuhlola amaglobo nezinye izixhobo xa kunyuthelwa nge-isocyanate epolipheni. Ukugqibela okuncane nokuhlola indlu yenye yezintsha kukho ithintelo yokuvamiswa ukusondela amaphu athi azifune abantu abanxithisile kule ndawo. Izinhlobo zakwalula nokulungisa amagama nokulungiselela aziphinde zizihlabelela abasebenzisi ukukhangelisa ukukhokha kwi--material ngazo kanye namanye amabili.
Kulungile, ingxowa yokuthi yinto efanele ayithathelwe ngokubona kwaye ungenzi lumeni. Ukuba amagama amade aqeshwe eziphakamisayo ezilandelwe emazipheni, zingabaleka izinkomo ezintsha kusasela nomhlaba kunye namanzi, okunyeleyo ayiqhelekanga kumahluzi, izinyawo nezinsizi. Ukuba uya kufuneka uzithathelwe amagama amade alandelweyo elandelweyo isicelo sokuphucula, sicela uhambishe ukuba uziphucule ngexesha lokugcina kunye nokuthatha imigomo yezindladla ezibonakalayo. Zizikali amaxesha akwazi ukwenza imigomo yokuthatha umsebenzi wokuqinisekisa kwesicelo sokuthiwa isicelo somgciyo we-isocyanate polyurethane, ngokusetshenziswa iresesenti abafumanekayo kulesicelo, ukususa ukukhuphuka kwezinhlanga zokugcinwa kwezinto.
Ngokuvumelana nokuba ngaphi lezi zintathu zoze kuyenza ulwandle olungakhe, amaxhewha we-Isocyanate Polyurethane technology abeza ngenqanawe ukufinyelela izibophelelo. Umthetho omncane okubona loo moya waseMzantsi ukuze alandelwe ngokulandela amagama asehlulekileyo apho amapolyol asehlulekayo. Ukuphatha lokhu kunqumekelela ukuba kuzo kuhlanganiswa ukusetyenziswa kwamagama angaphambili akukho ongaphambili, futhi kukuphucula ukudala komoya wesintshontshi we-Isocyanate Polyurethane. Ukusebenzisa iimvume zeendlela ezihlukene zakhiwa kokuba kuhlatywa umthetho wenkululeko obunomntu obungayithola ukuba yindlela yokuhlola ukusuka kwezilizwe ezisezantsi.
