Ukuthenga Okungu-kgcwele Wohlelo Lwesithuthi se-Polyurethane Oshayayo - Ukusebenza Kukhuni Okuningi Kuneminyaka & Ukunciphisa Ingcosto

Isiseko sangaphandle sokuphutha pu sokuphuthela ngokugcwele sibonakala kumthombo wobuza ngoba kunezinkalo ezihlukene zokusebenza okunempilo okubandakanya ukulungiswa kokwakhiwa nokuphatha izindleko ekwakhiweni kwamaphoyila. Ngaphandle kweziseko eziqinile ezingadinga ukubuyiselwa kabusha emva kwezikhole zimbalwa, le fomule eyisinkingi isebenza kakhulu kizinsuku ezide, njengoba iphinde iphinde kangaka kuzikhole 50-100 ngokulinganayo kusayensi noma imithetho yokusebenza. Lokhu kubaluleka kakhulu kusindiso sekhasimende esisodwa esingapheli phansi ngapha kwezimali eziphakeme ezenziwa yizikhathi ezingenazo umsebenzi. Ababhali basebenzisa izikhathi zokulungiswa ngendlela efanelekileyo, baya kunciphisa izishotho ezingavunyelani futhi bahlale bezilungiselela iziseko ngendlela efanelekileyo ukuze kube khona inkonya enkulu. Isiseko sangaphandle sokuphutha pu sokuphuthela ngokugcwele sibonakala kakhulu ngokuba kusebenza kakhulu, lokhu kubiza izindleko zezinto, ngoba izinto ezingapheleli zisetshenziswa ngolunye uhlelo olukhulu. Ukubaluleka kakhulu kusebenza kakhulu, lokho kubiza ukuthi izinto ezakhiwe kizikhathi zokuqala ziyafana nezinye ezenziwa kizikhathi zokuphuma ekugcineni. Lokhu kubaluleka kakhulu abakhiwa abasebenzisa izimali ezingabangeli izinto, lapho izici zezinto kumele zibe khona kizindlela eziningi. Inkimbinkimbi ibaluleke kakhulu uma kucabanga izimo ezinhle nezidingekayo, izindlela ezide, noma izici ezivuthiwe lapho iziseko eziqinile zazigcina ngokushesha ngoba zingahloseki kakhulu. Isiseko sangaphandle sokuphutha pu sokuphuthela ngokugcwele sibonakala kakhulu ngokuba kusebenza kakhulu, kufana nezindawo ezingcono ezingazange ziqede. Ukukhathala kwezinkanyezi kusebenza kakhulu, ngoba isiseko singasebenzi kakhulu kuzo zonke izindlela zokusebenza ezenziwa kumaphoyila, kusukela kuzo zokushisa kuzo zokushisa okuphakeme okuphindaphindi kangaka kuzingu-200.

Isivikeli esikhulu se-pu foam esibuyiselwe ngokugcina siphinde sithole amandla okuthuthuka kakhulu kumelisa ukulungiselela kwezimali zokudala nokuncipha izindleko ngokuthenga kakhulu ngendlela ethinta izimali ngokushesha nezadlule. Le ndlela isebenza njengenkinga eyisisekelo ekulondolozeni izindleko futhi kufanele kube khona umlando wesilinganiso ngaphandle kokulahleka kwezici zezinto. Indlela yokuthenga kakhulu yalesi sivikeli esithile isiza kuncipha izindleko ngokujikeleza kunazo ezinye izindlela zokuthenga eziphansi, izindleko zingaba phakathi kwe-15-30% ngokulinganisa nokuthi yini na imali engathengiwa noma izimo zokuthengisa. Le mlando ingxenye kakhulu kwizimali ezinengqondo ezingaphezu kwebude, ikakhulukazi kumelisa abathengisa kakhulu abadinga izilungiso ezinkulu zalesi sivikeli ngamuhla. Ngaphandle kwezindleko ezinciphayo, ukuthenga kakhulu kwe-bulk buy self skinning pu foam release agent kusiza ekulondolozeni izinqubo zokuthenga ngokunciphisa ubuntwana obuthile bezimali, izivikelo, nezidingo zokuthunyelwa. Le ndlela eluhlaza kusiza ukuthi izigaba zokuthenga zihlale ziqhubeka zasebenza kuzinye izinto ezibalweni ngokuphepha izindleko. Ukuphatha izicubu kusiza ekulondolozeni izimali, ngoba amelisa angakha kubekela izilungiso ezifanele ezingaqeda izindleko zokugcina kodwa zihlale zihlambulukile. Ubude bekhathi lesicelo se-bulk buy self skinning pu foam release agent lubamba le ndlela ngokuphepha izici zalo lapho lisegcinwa ngexesha elide. Ukunciphisa kweziphazamiso kwezimali kuyindlela engeyi yodwa yokuthenga kakhulu, ngoba amelisa angagcina izilungiso ezifanele ukuze acindezeke kuziphazamiso, ukukhula kwezimali, noma izidingo ezingalindelekile. Ukulondoloza kwezimali kusiza ekubeni kwenzeke uhlelo oluhle olunembile kakhulu, ngoba abahlaziyi bangasebenza ngobubele konke bethu bethu besivikeli singabangaki. Ukuthenga kakhulu kusiza ekulondolozeni izimali, ngoba amelisa angagcina izindleko zezinto ngexesha elide futhi angavidi izindleko ezishintshashintsha ezikhiqizwa yizinto ezincinci. Izinkinga phakathi kwezivikeli ne-melisa zihlola ngale ndlela, futhi kakhulu zizothola inkululeko, inqubano yesayensi, nokuthandwa kakhulu xa kuneziphazamiso.

Isiseko sebuya kakhulu sokugcina pu foam sibonisa ubunzima ngokuba sifakelana ngokujulile ngezinhlelo ezahlukene zomphumela wophuqo polyurethane nezindlela zokwakha, ukuthi kube yisicelo esihle kakhulu kubawekeli abasebenzisa izinhlelo eziningi zezinhlotshwa noma abasebenta emaphethelweni amahle. Lokhu kukhona okujulile kususa ubuncinane nobude bakho obukhokhelwe ekugcineni iziseko ezithile ezikhethekileyo kuzo zonke izisebenzo, ukuphazamisa umbala wokugcina kodwa ukuqinisekisa iqiniso lezenzo zonke izidingo zokwakha. Isakhiwo sesiseko sasungulwe ngendlela yokuthi sisebenze kahle nenhlangothi epholile ye-polyurethane efakiwe kuze kube yinkimbinkimbi, izihlalo zamakhariya, izihlwayelelo zokulala, lapho igunya lesenzo nesimo sesayizi singaba yizinkinga eziphathelene nokusebenza. Ngokufanayo, isiseko sebuya kakhulu sokugcina pu foam sisebenza kahle kanjalo ngeziseko ezingaphansi kakhulu nezingaphansi, futhi kunezinhlelo zokucindezela, iziqhamo zokwakha, nezinye izinto ezikhululekileyo zezinhlelo zophuqo apho ukulinganisa kwezilinganiso nokholo kwesayizi kumele kube yilowo. Lokhu kushisa kuzingcinwa zonke izilinganiso, kusukela kuzingcinwa phansi kakhulu kuzo zonke izinto ezikhululekileyo, ukuqinisekisa ukusebenza okufanayo ngaphandle kokuthi izici zophuqo ziyini. Ukufakelana ngokuchemikhali kuyindlu enkulu, njengoba isiseko sisebenza ngendlela efanayo nezinhlelo zokhanyisa, izimpande, nezinye izinto ezisetshenziswa kakhulu kuzinhlelo zomphumela wophuqo ngaphandle kokuthi kuthinte noma kuthintele ngendlela engavamile engakwazi ukulahlekelwa izici zophuqo. Ubunzima be-temperature buhlanganisa ubunzima bokusebenza kakhulu, ukusebenza kahle kuzindlela zempilo zentliziyo nezindlela ezinezindlela ezithe phansi kakhulu ezinokufika ku-200°C noma ngaphezulu. Isiseko sebuya kakhulu sokugcina pu foam sifaka kahle kuzindlela ezahlukene zokwakha, kufakwa i-aluminum, i-steel, nezinye izinto zokwakha, ukuqinisekisa ukusebenza okufanayo ngaphandle kokuthi into eyayi yisiseko. Ukufakelana kwezindlela zokwakha kufakela izindlela ezijulile zokulayisha, izindlela zokunyusa kugcineni, nezindlela zokwakha ngokuphindaphindiwe njengezindlela zokwakha izinto ezibaleni. Izidingo zesayizi ezahlukene, kusukela kuzobuhle, izibonelo ezibonakalayo kuya kuzo zonke izayizi ezinehlabathi, zonke zifuna ukusebenza okufanayo kulesiseko. Lokhu kukhona okujulile kusiza abawekeli ukuthi babe nemfundo yokuthatha izigaba zokwakha, ukuvikela iziga ezikhethiweyo, noma ukuphendula izidingo zomphethelwane ngaphandle kokuthi kuthintwe ukusebenza kokesiseko. Isiseko sebuya kakhulu sokugcina pu foam sinesebenza esibonakalayo kuzo zonke izisebenzo, sivikela abawekeli abathembeka ngokuthi bafunde izinhlotshwa ezintsha noma bakhulule izimali apho ukufakelana kokesiseko kungabangela imiphumela yezehluko noma kudinga iziviko eziningi.
