Izicatshulenti Zokubuya Ezi Polyurethane Zokusebenza Kwesibhedlela Somoto: Ukusetyenziswa Okukhulu Nalokho Olungakhiwo

Zonke Izigaba

umcweba wopholiso olusebenzisiwe ngokwesobizo somoto

Izindawo zokulayisha polyurethane zikhetho emanzini kwi-phakethi yokugcina imibhayiso yemakhadi, ezilungiselelwe ngokubhekeka ukusetshenziswa kwesiphumo sokulayishwa kwezindlela ezinamandla ezinikezela ukususa izishi eziphuthumayo kwezindlela zocwaningiselo. Izindlela ezinhloko zihleli i-barrier yesikabi esincane phakathi komphathisi wocwaningiselo kunye nomthengi we-polyurethane, uvumele ukungavalekile ngaphandle kokuvumela umkhondo okanye umkhondo omuphi wamashumi amabini. Kwemibhayiso yobhaxi, lezi zindawo zokulayisha zikhetho emanzini zikhona ngokubhekeka kusetshenziswa kwezinketho zomoya kunye nezindawo zokulayisha ezithunyelwe nge-mist ngokukhetha izidingo ezidingekayo zocwaningiselo. Ipolyurethane release agents ezintsha zihlobene nokuhlola okuningi lokuncane lokusebenza, ukuze kube kuhluke kulayishwa ngaphandle kokucwangcisa umkhondo kunye nokuhlola okudingekayo. Zisetshenziswa ukuba zivumele umsebenzi wesikhatsi esiqhelekileyo ngaphambi kokufika kwendawo yokusebenza, uzokusetyenziswa kwezindlela ezininzi zocwaningiselo kunye nokuhlola okudingekayo. Ngakho ke, lezi zindawo zikhetho emanzini zisetshenziswa ukuba zivumele ukususa ukwakhiwo kwezindlela, ukususa isikhatsi somphathisi wocwaningiselo kunye nokuhlola okudingekayo. Ukusetshenziswa kwezi zindawo zikhetho emanzini zikhona ngokubhekeka kusetshenziswa ngokuzenzakalelayo ngaphansi kwezi zindlela ezinomsindo kunye nokusetshenziswa ngokushesha, ngokushesha ukudibanisa isikhatsi somphathisi wocwaningiselo kunye nokuhlola okudingekayo.

Ama-polyurethane release agents anikeza izinzuzo eziningi ezibalulekile emisebenzini yokukhiqiza izimoto. Okokuqala, zithuthukisa kakhulu ukusebenza kahle kokukhiqiza ngokwenza kususwe izingxenye ngokushesha nangokuhlanzekile, zinciphise izikhathi zokujikeleza, futhi zinciphise amanani okusetshenziswa. Lezi zinsiza zinikeza ikhwalithi enhle kakhulu yokuqeda indawo, ziqinisekisa ukuthi izingxenye ezenziwe zihlangabezana nezindinganiso eziqinile zomkhakha wezimoto ngaphandle kokudinga izinyathelo ezengeziwe zokulandela. Amafomu athuthukile atholakalayo namuhla anikeza ukuqina okuhlukile, avumela ukukhishwa okuningi kusuka ekusetshenzisweni okukodwa, okuhumusha ukusetshenziswa kwezinto ezincane nezindleko zokusebenza eziphansi. Ukuhambisana nemvelo kungenye inzuzo enkulu, njengoba izidakamizwa zanamuhla zokukhulula zenziwe nge-VOC ephansi futhi zihambisana nemithetho yemvelo yomhlaba wonke. Ukuhlukahluka kwalezi zinsiza kuzenza zikwazi ukusebenza ngempumelelo ezinhlelweni ezahlukahlukene ze-polyurethane kanye namazinga okushisa okucubungula, okunikeza abakhiqizi ukuguquguquka ekusebenzeni kwabo. Zisiza nasekwandiseni isikhathi sokuphila kwesikhunta ngokuvimbela ukugqoka nokunciphisa imvamisa yokuhlanza nokunakekela. Ukuphepha kuqiniswa ngokusebenzisa amafomula angenabuthi avikela impilo yabasebenzi ngenkathi kugcinwa izindinganiso eziphakeme zokusebenza. Ikhono lokufinyelela ikhwalithi yendawo engaguquguquki emizileni emikhulu yokukhiqiza liqinisekisa ukulawulwa kwekhwalithi okunokwethenjelwa nokwaneliseka kwamakhasimende. Lezi zinto zenza kube lula ukuba umuntu akwazi ukukhiqiza izinto eziyinkimbinkimbi zemoto ngendlela enembile.

Ukufakwa nokusebenza kakhulu nesibhedlela esikhangelini

Ukuphawuliwa kwezilungiselelo ezinomsindo zokuthatha amandla abangaphambili babo bokurephetha polyurethane ifanele yokuqhubeka ngokubuyile kakhulu kwisebentiso sokusebenza okulandelakayo kwegadi. Izilungiselelo ezinamandla ziziphumulekile ngokwesayensi esisodwa sopolimeri ukuba ziphawule interface lokuthatha olunemvume olungaphambili olusetyenziswa ngenxa yokuba kuzo zikhona izinto ezincinci ezifanelekileyo. Isitukiso somolekulo wakho wesilungiselelo siyibhucwe elitsheletsisiye lomdledi lokuthi luvumelana ngendawo yakho yezikhiyiwe zokubuyela, ukuze licinge inani lesikhatsi sezinsusa ukubuyeleka. Ukuphawulwa okuningi kunyalisela iimpahla emkhakheni, phakathi komoya omuchedwe nokuhlola kwesayensi sokusebenza, kunye nokuhlola kweziqhutyeni ezininzi zokuthiweyo. Ukuphawulwa kokuthiweyo kunjalo kufanele ngokugcina isikhatsi sesixhumanene esingabonakali kanye nokuphawulwa kokuthiweyo, futhi amandla akuphawulwa kakhulu kwiindawo eziningi eziphawulwa ngokubuyile kakhulu ezindaweni ezinathathu zokusebenza wezivathisi egaphazima ngeentsimbi enkulu apho ukuthatha umlando wenkcane nokusebenza okudingekayo kukuhlonishwa.

Ukuphatha Kwenkonzo neZihlangano Zokuhlola

Izicatshulwa ezincane zomoderni polyurethane zihamba emuva kwesiphumo sokuqinisekisa kwezinye izinto ezingaziphandleni kwenzeleyo ngokwesikhathi lokusebenza kweziqhuthu. Izindlela ezintsha ezahlukene ezibuyiswe ukuya kubona nokuba khona ngezilungiso ezincinci zezimali ngokusebenza okuphakamisayo. Amagunya amabasebenzi, ngokugcina, abangabizwa ngokuthi babuyeke kususa iimpendulo elandelayo leemoto engekuhlala ekhathaleyo, baphinda ukufinyelela umoya wendawo yokusebenza kunye nokuhlinza isiphumo sokudibanisa esiqhutyeni. Izinkinga lokuhlola lokuncane lavela ngokushesha ukunikeza amagunya engasophumelela ukusuka kumalume abanekutsi obungane ngaphandle kokucima inyathelo yesimo sokutshabalalisa. Izicatshulwa zibuyiswe ngokuthi zidinga amaxabiso aqondileyo aphandle kwelinye ilimi, kunye nokuziphindaphinda ukusetyenziswa kwezixhobo ezifanelekileyo ukususa ukusetyenziswa komncedo kunye nokusetyenziswa kwezinye izinto ezincedwe ngokusebenzela. Lolu hlobo lokuhlola nokuhlola kuhlanganisa nokuhlola kakhulu kuhlawula kule ndawo yokusebenza, phakathi kokusebenza kunye nokusuka, futhi kuhlanganisa ukusetyenziswa kwezicatshulwa ezincane zokuthuthukisa kumthetho wesikhephe sokusebenza kweziqhuthu.

Ukuphatha Kwesiphumo Sesifacesi Nokugcina Ukusetyenziswa KweMold

Umkampani wesithuthi esophistekedi wakwa polyurethane uyasibuyisela ukusukela kweqhosha lokusebenza lomphahla ngokupheleleyo ngenxa yalokubonisa ukuphatha okulandelayo kwezinhlobo zomthombo. Izithuthi eziningi zilanda umthengiso omnyama ofanele olungayiphasa ukusuka kodwa kunjalo uzokusetyenziswa ukusetshenziswa sesiqhina somphahla wezindlela ezimoldwe. Umthengiso womlilo omncane owabizwa ngazo zingasemukelwa izinsuzwano ezikhulu zomphahla ngokushesha njenge pinholes, amablisters, kunye ne flow lines, ungene amanxaso akhona amahhovu aphandle kokugcina. Ngokuhluke, iinkomboni yokuphasa lezi zithuthi zinatsha usuku lwemthombo ngokungavunyelwe ukufunda kwepolyurethane kunye nokucutshwayo kwezinhlobo zomthombo. Lokuhlola phakathi kweqhosha lokusebenza kunye nokuphasa komthombo ungene imali ekubaleni ngokuthi kukhona ukusethenziswa kwenqanawe kunye nokusetshenziswa kwezindlela ezimoldwe. Ukusetyenziswa kwezi zithuthi ngaphandle kokuthi baye bakhawuleze ukusukela kwezinye iindlela ngendlela yobudala ubuye abesetshenziswa ukusetshenziswa kwezindlela ezifanele, uzisetshenziswa ukuba zihlobene nezinto eziphumeleyo zokuthiwe kumngeni.
