I-PU Release Agent Engenisi: Isiphumo Esikhona Lwendawo Yokusebenza

Zonke Izigaba

umphawuli wemoldi wePU

Umsho wokulanda PU yihlobo lesikhemele esizenzekelayo lokuhlola ukuba amahlaba abe ngaphandle kwezihlabele ezinamandla zezombili ngesikhathi sonyusela. Lolu hlobo oluhlukekile lomgciyo lwesintu kulungiselela umthombo omncane phakathi komphathisi wesihlabele kunye nomnyama wasePU, ulungiselela ukubonakale ukubuyibhala ngendlela engcono nokugcina uhlobo lwesilayithi olusemva. Isimo esisetyenziswa phakathi komsho wokulanda PU sihlukile isikhemele esisindumiso nokuphakamisa ukwakhiwa kwesifazane sokuhlola ukubuyibhala okanye ukufinyelela ukusetyenziswa ngokuziphumelela izilayithi zokuhlola ngokuncane ngokusho nokuthi akukho usunguliweyo phakathi komphathisi kunye nokulandelana. Lezi zinhlobo zisho zizihlukene ukusetshenziswa nokusetshenziswa ngezinye izihlabele zesiphenjisi esizidinga ukuseta polyurethane, futhi amafomula amadine amahhululekile amasilinga, amawexu, okanye amanhlobo ohambisana nobungakanani obungqongqo. Ukufomula kufuneka kube ngokudibanisa isilinga, amawexu, okanye amanhlobo angaphandle apha ayiqinisekise ukusetshenziswa ngokupheleleyo ngeminyaka emingqi. Ngokushesha, lezi zinhlobo zisho zikwenza ukusetshenziswa kuhlukekwazi ukuseta imigomo yokusetyenziswa, ukususa iimfanelo, nokugcina ukusetha imigomo elandelayo echanekileyo. Zihlukene kakhulu ngokusetshenziswa phakathi komsebenzi wesintu wezombili, ukuhlolwa komphathisi wesicota, ukusetyenziswa komphathisi wesicolo, ukusetyenziswa komphathisi wesikrasi, kunye nezinye izindawo ezinamandla zasePU zihlukene kakhulu. Iisho ezintsha zePU zisetshenziswa ukuba zibe ngokulandelayo, kunye nenkinga eyenziwayo ngokuthi kunezifomula ezinamandla ezinamandla ezinikezeliweyo ukuthi akukho iVOC ezincinci kunye nemibhalo ebhokisayo.

Amagama-okuqinisekisa lwePU ngamakhulu amabangeni okulandelayo ezifaneleyo ngenxa yokuba zihluke kakhulu kuzama ukusetyenziswa ngokubanzi kwiiphrojekthi yezilungiselelo ezintsha. Ukuphela kunye nekuhlola kakhulu, bayathatha isiqinisekiso sasendaweni sokuthi bavumele abasebenzisane bakwakhe amapoti emazweni ngaphandle kokuthi kuhloniphe umla wokusebenza, lokuthi kuhlukene amalayithi nokuthi akukho imali elishwa. Izindlela ezinhloko zizoba ukusetshenziswa ngokuphi ndawonye ukuze kube noma kupheli ukusetyenziswa futhi kuhloniphe imali yesethelo. Lezi zingama-okuqinisekisa zikwenza uphawu olunomdlobululo olushesha kumapoti apho zibuyiselwe, uzame ukususa imali yesethelo nokuthi izigaba zingadliwe ngomoya ofanayo. Zihlabeleka ngokuphi na ukuthi zisetshenziswa ngazo kanye namandla amahhala amadifasini, ukuthi zikhona ngokugcina kakhulu kwiindawo ezidingekayo zokusebenzela. Ukusenzo kukhona phakathi komphilo, ngoba iPU amagama-okuqinisekisa azibonakale ngokubhekisisa amacompound esincinci nokuthi akukho amagama angaphansi kweVOC, ukuthi akhuse ukuseta indawo yokusebenza ekusetyenziswa ngenxa yakho. Ukuthi ziyathathela amaningi amapoti ngokusebenzela kunye nokuthi zikwenza ukusetyenziswa kakhulu, kuhloniphe imali yesicelo lokulawula. Ngeentsha kune magama-okuqinisekisa ayiqondisiwe ngamathambo, ukuthi bayenza ukuthi bayifinyele wezimo ezingcazeleyo nokuthi zibonakale kakhulu. Lezi zingama-okuqinisekisa zikhona ukuthi zingenhloso yokuhlala ngokubonakale kanye nokuthi zingaqinisekisa ukuthi amapoti angahluleke ngendlela edingekayo, okuningi lokuthi zikhona ngokubonakale kakhulu ukuthi zingabuyeleyo ukusuka kokuthi izindlela zezilungiselelo ezimfaneleyo zikhona ngokubhekelwa kwezindawo zokusebenza njengomoto nokuthathu.

Ukuphuculeka Kwesikhatsi Esiphuthumana

Ukuphumelela okubonakaleyo kwezilungiseleyo ze-PU zikhuluza ngokwesiphumo esisodwa kwezindlela ezinhloko zabo, ezizoba izilayezo emanzini okulula kunye nesibhedlela esihlinzekileyo phakathi kwebhetho kunye nokushelo lwepolipoliweithane. Isilayezo semicroni setshonalaza ukusetyenziswa ngaphandle kokuthi ishilo shemukise ukuze kube kusenziwe ukusetyenziswa kunye nokuhlola kweqembu lwebhetho kunye nomntla wokuqhuma. Ukufakelwa okunikezayo kwezilungiseleyo zikhuluza ngokwesiphumo sasetshelela ukubuyela ngenxa yobhetho, ukuba kuhlobene ngephrofayili elinyeleyo lokusebenza lokugcina ukusetyenziswa oluze luhlabeleke kuzama ukusetyenziswa ngamabhalisi amaningi. Lomsebenzi oluhlabelekile kuhlatywa ukusebenzisa kwakhona, ukuba kuhloniphe umthetho womncedisi wokuphumula kunye nokuphucula ukusetyenziswa. Ukusetyenziswa okubonakaleyo phakathi komkhulu webhetho kuhlatywa ukusuka ngendawo yokugcina okanye ukusetyenziswa engapheleleyo, ukuba kuhloniphe uphawuli lwento yokuhlola kunye nokususa imibhalo.

Ukuphumelela nokuhlola isibhedlela

Izandla zokusetyenziswa ezintsha kwePU zikhululekileyo ngokubheka isenzo sethu kunye nokuhlola kwezinhloko. Izindlela eziphumaphi ezinzalo zihlukaniswe ukuba angamashumi amadluli amabili weVOC (Ama-Volatile Organic Compound), ukuze ufikelele okanye uzibuyekeze izicatshulwa zokususa ngezindlu zokugcina zomhlaba. Lezi zinto ezikhululekayo zihlala ngokuthi zingcinane ngokwesiphumo sakhe ngokungakuhlobene nokuphakamisa umphathiso wakhe wesikhatsi. Njengoba, iimitha engaphezulu yizinto ziyahlukene neezindawo ezinomsindo, uzoba ubhekene ngenani lokusebenza olungaphandle kokusetshenziswa kwezinye izinto ezifanelekileyo ezinomsindo. Izinga lalokusetshenziswa lusetyenziswa ukuba libe ngaphandle komoya omkhulu ngemperipharasi, lokunje ukusetshenziswa kwemfene engacabangeleyo okanye imigomo yokubhedelela. Ukufaka kwehlola lokuncedisiwe kuhlonelwa phakathi kwezilondolozi leproduksi, kusetyenziswa kunye nokususa.

Ukushayela Kwesikhashana Sokudibanisa Okuningi

Ukufakwa kwezilungiselelo zomsebenzi wokuqala wesayinti PU binga amahhovini angasenziwa ngaphandle komhlaba phambi kwezilimi ezifanekiso. Ukusethenziswa kwabo okukhangelwe kuhlu kunakenako amakhulu amacala akwesayinti ngenxa yalokho kuzoqaphepha izikhwalezo ezimbili, ukuze uzisuse ukusetyenziswa kwamathathu nokulandelana nokuthuthukisa. Iziphiwo lezilungiselelo zihlobene ngeendaweni zokugcina, ukuze zizibuyele umdlalo omusha nokusebenza ngokupheleleyo. Ngokubhekisisa ukungena imithombo yamathebhu emagqweleni, lezilungiselelo zikhona ukungasebenzisa ukulanda nokuhlola, ukuze zizidingise izinyathelo ezinethunywa nokusetshenziswa kwezinye izinyathelo. Ukusetyenziswa kwezilungiselelo ephakeme zikhona ukuba amandla abezine esebenza ngokuphumeleleyo, ngenxa yalokho kuzoqaphepha amandla amabili nokusetshenziswa kokuthuthukisa. Ngokushesha, ukusethenziswa kwezilungiselelo ezinethunywa zikhona ukuba ziyafuna ukusuka ngokuphela ukuthi azisetshenziswa amaxhobo amanye aphandle komhlaba okanye ukubuyiselwa.
