Umthwalo Ophambili Womtheleli Wesivuno se-PU HR - Isisombululo Esinehlabathi Kukhiqiziwe kwezimali kwiManufacturing yePolyurethane

Isivumelwano esingcono sokuthutha pu hr siqinisekisa ubungakanani bokhokho-inkhokho obandakanyayo okuthuthukisa izimali zokwakha kwezinhlelo zokwakha izinto ngokuqhuma. Lokhu kufanelekile ukuthi kuqukethe umthombo wekimikhali ongenhla okuphumelela kakhulu emsebenzini wokwenza into ekhokhelwayo ngaphansi kokunciphisa izinto ezinzima, futhi kube yinto etholakala ngokucophelela kwizindleko eziphethilene nezinye. Iziphumo zezenzo ziyase phambili kunale ngezigaba, kuzokwenzeka ukunciphisa isilinganiso senkama yekhemikhali ehlotshelwayo, ukunyezwa kwebala elide ngalunye uhlelo, nokunciphisa isikhathi esidingekayo sokubuyisela isivumelwano. Izikhala zokwakha zithola izindleko eziphazanyayo ngokuvuthwa kwezimali nezinkinga, ngabe zilandelayo izindleko ezingu-20% kuze kube ngu-40% kunazo ezinye ezibalulekileyo. Isivumelwano esingcono sokuthutha pu hr sifika kulezi ziphumo ngaphandle kokuchaza ubumbiko bezimali, bahlala bathatha iqiniso lesebentulo ngamathuba angu-1000. Ukugcina ubumbiko bokhokho bokomphakathi bubonakala ukuthi lesi sivumelwano sibuyekeza amava amandla, ubuhle besenzo, nokuthuthulwa kwesitsha. Inkomo yokwakha ikhathazwa ngokusetshenziswa teknoloji ye-polymers engunyanzelwano, eyayiqinisekisa ukuthi inkohlaka ayizange iphazimule kakhulu, futhi ukunciphisa izindleko akulungele ukunciphisa ubusebenzi. Izindleko ezingcono ngokudala zibonakala kangcono ngokunciphisa izidingo zokulungisa iimodi nezindleko zokusebenza kakhulu. Amaphropati okulungisa kalesi sivumelwano sokuthutha pu hr sikhuselela imodi engcono emandleni yesivumelwano nemva yokuqina, futhi kakhulu kusabalala inhlaka yalo. Ababhali basekhaya babeka iziphumo ezilungile kakhulu uma bamenze ukuhlela lesi sivumelwano esinezindleko, ngabe isikhathi sokuhlala kubo singu-zinsuku kuphela ngenkathi kungaba ngu-zineminyaka. Ukuhanjiswa kwezindleko kubonakala kakhulu kuzinhlelo zokwakha ezikhulu lapho ukunciphisa kancane kakhulu kanye nobude busha kuthatha isilinganiso esikhulu kwi-zindleko zonyaka. Lesi sivumelwano sokuthutha pu hr sinquma abazikhiphayi abancane ukuthi baziveze kahle ngokunciphisa izindleko zakho zokwakha kuze kube ngeminyaka etholakala kuphela ngabazikhiphayi abakhulu abane amandla okuthenga amakhulu.

Isisekelo sokukhupha ku-PU HR esheshayo sikhuthaza teknoloji encono yokungakhathalwa kuchemikhali esibekela amastandela amasha kulokhu kuyasebenza nokusebenza kahle emazingeni aphikisanayo ekwakheni. Lo mkhawulo ongcono usebenzisa imithombo ye-polymer enguqu ngokweqile ukwakha izizinda ze-molecular ezingavumeli ukuthi chemikhali azungeze kube yisikhathi eside. Amakhemikhali akhathalwa ngu-lo sisekelo sokukhupha ku-PU HR esheshayo asethuliwe ngokujulile ngokulinganayo kwamakhemikhali, i-solvents, nezidingo zokwakha ezihlala ziqashelwa ekwakheni kwe-polyurethane. Izivivinyo zonke zibonisa ukuthi kakhathalekile kuma-isocyanates, ama-polyols, izixwayiso, nezivivinyo eziphazanyiswa ezihlala ziphepha izisekelo zokukhupha ezijwayelekile. Lokhu kukhathalwa okungcono kubalulekile kakhulu ekunikezeni isikhathi eside sokusebenza nokuncipha kokubuyiselwa, kungenza ukuthola izindleko futhi kuvuselela ukugcina kokwakha. Isakhiwo se-molecular yesisekelo sokukhupha ku-PU HR esheshayo sikhona ama-networks a-across-linked a-polymer afaka ubunzima noma kube kukuphi okusha, ukuqinisekisa ukuthi izici zokukhupha zilindele kusikhathi sonke sokusebenza. Izivivinyo zokuguqulwa kwesitayela zibonisa ukuthi ukukhathalwa kuchemikhali kuhlala kuzenzele kuyo yonke indlela yomlando wokusebenza, kusukela emhlabeni wempilo kuya kumlando ophakeme we-molding owepasile amade 200. Umkhawulo ongcono ungavimela ukuthatha kwezichemo phakathi kwezisekelo zokukhupha nezinto ze-polyurethane, ukucima amathuba okuthintwa okungaba yinkinga eyenzela ukuthi izici zezinto ziqukethe. Izivivinyo zokudala kahle zibonisa ukuthi lo sisekelo sokukhupha ku-PU HR esheshayo sakhathaleka kuchemikhali noma kube sekuphileneyo, ukuqinisekisa ukusebenza okuhle noma kube kukuphi okusha. Ubunjinga bokukhathalwa kwezichemo kwalokho kucima izinkinga eziphathelene nokusebenza kwezisekelo zokukhupha, ukuqinisekisa ukusebenza kwebhloko futhi ubunzima bephansi kwezimo zomdlalo. Izivivinyo zomhlaba kumazinga aphikisanayo ekwakheni kubonisa ukuthi lo sisekelo sokukhupha ku-PU HR esheshayo usobala kakhulu kwezinye izinkampi, futhi kakhulu kusebenza kuthathu kuya kude kushiyagalombili ngaphandle kokulingana komsebenzi. Izinhlelo zokuphatha ubunzima ziqinisekisa ukuthi ukukhathalwa kuchemikhali kuhlala kuzenzele kuyo yonke indlela yezinhlotshwa, ukuqinisekisa ukusebenza okufanelekile okukhathalekile okukhuthaza ukuplanisha kanye nokubala izindleko.

Isivikeli se-pu hr esheshayo sibonisa ubunjwa obungcono besiseko sobuchule okwakhiwe ngokucophelela, okwenzela ukuthi kube yindlela eyafisayo kubalimi baphatha izinhlangano ezahlukene zokwakha nezidingo nezimiso eziyinkululeko. Lokhu kubunjwa okumelene kusuka kuzimiso zokwakha okuhle kakhulu okusebenza ngokuvamile phakathi kwezinhlangano ezahlukene zemoldi, izilinganiso zempilo, nezindlela zokwakha. Ubunjwa beleyo isivikeli se-pu hr esheshayo buhamba phambili ekuxhaseni nezindlela ezahlukene zokusebenzisa, kufaka phakathi izixhobo zokushisha, izixhobo zokubhinisha, nezixhobo ezihlala ziqhubeka zinikeza umdalo ukuze kugcinwe imfundiso yesiseko sokwakha ngaphandle kokudinga kwebhujethi enkulu. Izimiso ezahlukene ze polyurethane zifuna kahle leli sivikeli se-pu hr esheshayo, kusukela ematholeni aphathekayo atholakala ekwakheni izindlu kuze kube ngemathole amandla apholileyo atholakala embonini wemoto nasezintandazweni. Isimo sezimiso sibuyisela ngokuvamile phakathi kwezikhathi zokuphila, kusukela emahora amahle akudingayo ukususa izimpawu ngokushesha kuze kube ngokuphila okude okudinga ubunzima obudala. Uhlolo lomlando wokuxhasana lukhombisa imfundo engcono phakathi kwezilimi ze-steel, aluminum, composite, nezilimi ezithile zemoldi, likhula ukudinga kwebhujethi eluhlaza kanye ngezinye izivikeli. Ubunjwa bezintamo bekhipha leli sivikeli se-pu hr esheshayo ukusebenza ngempilo emthwethweni futhi kumthwethwo ophezulu, ukuvikela izidingo eziyinkululeko phakathi kwisiseko esisodwa. Umkhuba wokwakha unika imfundo ephephile kwezinye izici ezitholakala nge-water-blown ne-chemical-blown polyurethane systems, uqinisekisa ukuba kunezimali eziphakeme phakathi kwezinhlelo zokwakha ezahlukene. Igeometri yemoldi enobunkemkonto ayizange ibe yinkinga kule sivikeli se-pu hr esheshayo, ngoba kunezilinganiso ezivamile zokufakwa nokususa izimpawu emadeteleni amahle, emacubeni, nemagugu amaphansi angayiphikisa izivikeli ezijwayelekileyo. Ubunjwa bezindlela zokwakha bubonisa ukuthi le sivikeli se-pu hr esheshayo isebenza ngokufanayo emsebenzini wokwakha izinto ezishiyekayo kanye nezinhlangano ezikhulu ezisebenzayo ngokuphumelelayo. Amasimo ethekwane ayizange abuye ngaphezu komthetho wezindlela zokusebenzisa noma ubungakanani be production, uqinisekisa ukuthi abalimi bangabeka khona emfundeni ebhekene nomdalo wazo wonke. Ubunjwa buhamba phambili kumsebenzi wokugcina, nobunjwa obungcono kwezixhobo zokubhinisha, ukudibanisa, nokugcina okungaba ngemuva kokususa izimpawu. Ukuvikela kwezimo zezinkangala kuvikela le sivikeli se-pu hr esheshayo ukuba libeke imfundo yalo phakathi kwezilinganiso ezahlukene zehumidity, empilo, nezinkinga zokulahlekelwa ezitholakala kakhulu emazingeni yokwakha.
