Umcingo wesolwandle wefothi oqondileyo wezokuphefumula kwi industri yesilawuli - Izisombululo ezihle ngaphakade yokuphelula iimoldi

Isisekelo sangaphandle sefothi esiphaziywa ngendlela esobala esenziwa kumongo wesilungelelo kusenziwa kwezinhlelo eziphethwe kakhulu ngokuthi kwenza isivimba esincane kakhulu esilinganiselwe phakathi kwezinye zomlando nezinhlelo zepolyurethane ezingaphakathi. Lokhu kusivimba kukhinda ukudluliswa kwezimilo kumakro-molekiyuli ngaphandle kokulahlekelwa kwezinxenye zephufo nezilinganiso. Isimo sesisekelo senziwa ngendlela esihlukile, kufaka phakathi izici zokuhlukana ngendlela yomthwalo nezokungahlangani ngendlela yezinhlelo zepolyurethane, okunika imiphumela engcono kuzindlela zonke zokwakha. Ukuzimisela kwezinkeleni kuyisahluko esibalulekile kule miphumela engcono, ngoba isisekelo sangaphandle sefothi esiphaziywa ngendlela esobala esenziwa kumongo wesilungelelo sibonakala ngokuthobela kusenziwa kwezinhlelo yephufo, kusukela ekumisweni kwezinkeleni ezingaphezu kuka-100°C kuya ekupheleni kwezinkeleni zomhlaba. Isimo sokulinganisa sikhulula izinkinga zokwakha eziphaziywa kakhulu, njengoko zinxenye ezingalinganiselwanga, izilinganiso ezingahambelani, noma ukungasivikelwa ngokuphelele okudinga ukusebenzisa amandla. Izivikelo zokulungisa ubunzima zibonisa ukuthi izindawo ezisebenzisa le nqubo esihlukile yesisekelo sangaphandle sefothi esiphaziywa ngendlela esobala esenziwa kumongo wesilungelelo zifinyelela izilinganiso zokusivikela ezingaphezu kuka-99.5%, ngumlando wokusebenzisa izinqubo eziphethwe ngokuvamile eziphaziywa ngokwengeziwe kwezilinganiso ezingaphansi kuka-95%. Lokhu kungcono kumphumela kusizinda sokwakha esilinganiselwe, amandla afunekayo angaphansi, nokuncipha kwezivikelo zokulungisa ubunzima. Ukubaluleka kwayo kumzobo wonke, kufaka phakathi i-aluminum, i-steel, nezinye izizinda, kusivikela ukulinganiselwa kwezimiphumela ngaphandle kokuthi izici zezixhobo ziyini. Abasebenzisi bezinhlelo zephufo bafuna ukuncipha kwezikhathi zokwakha ngoba ukusivikela kusivimba kusivikela izikhathi ezikhuthazekayo ezivela kumzobo othile noma ukususa okudala inkohlakala. Isiphumo sezenzo kule miphumela engcono kufaka phakathi ukuncipha kwezindleko zoksebenza, ukunakekelwa kwezimali zokwakha, nokunyakaza kwezimali kumazwe okudinga ubunzima obulungile kakhulu kumazwi. Izivikelo ezidlule izikhathi ezide zibonisa ukuthi isisekelo sangaphandle sefothi esiphaziywa ngendlela esobala esenziwa kumongo wesilungelelo sibonakala ngokuthobela kusenziwa kwezinhlelo yephufo, kusivikela abasebenzisi ngezimiphumela ezithobelayo ezingcono kakhulu kusivikela izindleko zokusebenza kanye nezivikelo zokulungisa ubunzima ezingcono kakhulu kumazwi abantu.

Amathuba okulungiselela kwe-soft foam release agent yomthombo wokulala akuphumelelanga ngaphandle kwezinkundla zokudonsa okujwayelekile ukunikeza ukulungiselela komthombo ofakazelayo okwenzela ukuthi izikhathi zombila zingathandabuzeki futhi kube khona ubuncushisi bezimali yokulungiselela. Lo mkhawulo ophuthumayo uwakha isivimbo esingu-molecular level esivikela i-polyurethane foam ukuthi ingahlukananga nomthombo, kanti kanciphisa ukuhlukunyama nokulungiswa kwesayizi okuholela kuma-demolding amaprojekthi. Ifomula yento inamagunya afaka okuvikela ngqo kumahlaza evela kwi-polyurethane components, ayavikela ukucindezelwa kwezihluko, ukuchithwa noma ukulahlekelwa kwebhodi engaqondakali kakhulu emva kwezikhathi eziningi. Ukuvikela kwingxenye eyenza umsebenzi omuhle, njengoba i-soft foam release agent yomthombo wokulala ikhona isimo sokuvikela xa kusebenziswa kumathelelo aphelele apho kususwa i-foam, ayavikela umthombo ukuthi angacindezeke. Isivimbo sasayizi sasayina ukugcina izimpilo zokwakha, sikhonza izihluko zomthombo zokuthi zizimele ekususweni kwe-foam ngaphandle kokudinga ukucopheleka kangcono. Izifundo zekhono zibonisa ukuthi izimbotshane ezinikiwe le soft foam release agent yomthombo wokulala ziyasebenza kakhulu kangethu (300%) kunazo ezidingi ukulungiswa noma izisiko ze-release systems. Lokhu kubangela ukuthola izimali eziningi kubalimi abangeke bafuna ukulungisa noma ukubuyisela izimbotshane ngokusheshayo. Lomkhawulo wokulungiselela ungcine izinto ezibalulekile zomthombo njengezindlela zokuhlisa, izindlela zokuhlanya, nezihluko ezinhle zasayizi ezinconywa ekususweni kwe-foam. Izinketho zokulungiselela zizimele kakhulu futhi zingasheshi, kanti kanciphisa izigaba zokulungiswa, kanti kanciphisa izigaba zokulahlekelwa kwezisebenzo. I-soft foam release agent yomthombo wokulala ivikela ukuthi izinto zingagcinwa kakhulu ezidinga izindlela eziningi zokucopheleka okuvikela ukuthi izimbotshane zingacindezeke. Ukwabiya kwezihluko kubonisa ukuthi izimbotshane ezinolungiso ziqinisekisa izilinganiso zeqiniso ne-integrity yebhodi emva kwezisebenzo eziningi, kanti kanciphisa iqiniso le-foam esayizi esayidi esilungileyo esifakazela izici zomthombo wokulala ngokufakazela izidingo zezimali zokulala.

Ukusebenzisa kwezixhobo zokulula esizatsheni ngaphandle kwebhedli njengeyomthwalo kusenza izinyathelo ezifanelekileyo eziphumelelayo ekusakelweni ngokuphindaphindwa kwemiphumela ethile eyodwa yekusakela okuyinxalenye eqheleka kakhulu emfukweni wokuthengisa nokuthuthuka. Ukuncipha kwesikhathi sokudluliswa sisilungile kakhulu, njengoko ukulula kakhulu kwebhedli kususa izigqibo eziphathelene nobuchwepheshe bwebhedli, imisebenzi yokukhupha ngendlela engcono, noma ukulahlekelwa kwebhedli okuthintana nokusakela. Uhlaziyo lwebala kuzindawo zokusakela lukhombisa ukuthi ukusebenzisa kwezixhobo zokulula esizatsheni ngaphandle kwebhedli njengeyomthwalo kunciphisa isikhathi sokudluliswa ngaphakathi kuka-15-25%, kuvumela ukunikezwa okuningi ngosuku ngaphandle kokunika imali ebaleni elide kumashine noma kuzindawo. Ukusebenza kwezimali kuhleleka kakhulu njengoko abasebenzi bakhetha isikhathi esingaphezu ekuphileni kwezinkinga zokulula kwebhedli futhi bakhetha isikhathi esingaphezu emisebenzini yokusakela enezimali, kubaluleka kakhulu ukusebenzisa kwezimali futhi kunciphisa izidingo zokusebenza ngaphandle kwegazi. Ukusetshenziswa kwamandla kunciphisa njengoko amashine asakela ayasebenza ngokushesha kakhulu ngaphandle kwezikhathi ezide zokugcwalisa noma ukusebenzisa amandla akhona okudingeka ekuphileni kwezinkinga zokulula kwebhedli. Okunciphayo kumalimali kufaka phakathi ukunciphisa kwebhedli, njengoko ukulula kwebhedli kususa izimpilo zebhedli ezithintekayo ekuphileni kwazo, kuhleleka kakhulu umkhawulo wamalimali futhi kunciphisa izindleko zomlando ngayinyaniso. Izindleko zokulawula ubunzima zihleleka kakhulu njengoko izixhobo zokulula esizatsheni ngaphandle kwebhedli zibonakalisa izinto ezifanayo ezingcono ezinciphisa izidingo zokuhlola nezinkinga zokubulawa. Izindleko zokulungiselela zihleleka ngokunciphisa kwebhedli, ukuphindeka kwebhedli, nokunciphisa kwezikhathi zokulahlekelwa okuthatha isikhathi nezimodi zokulahlekelwa. Ukusakela kusakela kuhleleka kakhulu nokuthembekile, kuvumela abasakeli ukuthi bathole izidingo zokuletha futhi balungise izinkomba ngaphandle kwezibindi zokucindezela ezingcono ukulungiselela izidingo zokusakela. Izixhobo zokulula esizatsheni ngaphandle kwebhedli zisiza ekusakeleni okunciphayo ngokuthintana nezinkinga zokuphinda, izigqibo, nezinkinga zokubulawa, futhi ziyasebenzisa kakhulu amashine nokuthwasa. Izibalo zokubuyisela kumali zibonakalisa ukuthi izindleko zokuqala zokusebenzisa izixhobo ezithile zokulula zibuyiselwa ngaphakathi kwe-3-6 izinyanga ngokuphindaphindwa kwemali, amalimali, ukulungiselela, nokuthuthuka kwezinsuku, kuyakha izixhobo zokulula esizatsheni ngaphandle kwebhedli njengeyona indawo ebalulekile kakhulu ekusakelweni kwempiyani.
