I-polyurethane elikhulu ziyinqubo elibonakaleni kakhulu emigomo engeziweyo kanye nezindawo ezinethuthukileyo xa kunjalo ngenxa yezilondolozi ezinethuthukileyo nokusetshenziswa olunye ukwesine. ISANYING iyinkampani elibonakaleyo lokushintsha amaxwebhu we-polyurethane elikhulu. Amaxwebhu angaphakathi akukho inani elipheleleyo kunye nokuthi zifundazela izindlela ezininzi zokuthi ziqhumelela kakhulu.
I-polyurethane elikhulu ingamandla okukhulu kumafakethi, izindawo zokugqibela, kunye nokuthi ayahlala kakhulu. Ngokuhlelo lokhu, ifanele kakhulu. ifomu yesi polyurethane esikhulu ngokwenqanawa kuhlanganiswa ukulanda amaxwebhu okufanele aye ngamandla nokuphathelana. Uma umsebenzi uthintela kwezinsuku zonke, iindlela zazifuneka zikhuseleke ukusetyenziswa ngakumbi, kunye nepolimeri yesithoba eside esiyaziyo ukuba yincane lokuhlala. Ungayipha inani lesihlanu ngenxa yokugcina okanye ukubuyisela isilimo, okungafuna ukuba kuhlukeka kakhulu ngazo zinto ezininzi ezizama ukuhlola kumashumi amabini.
Ukuphucuka nokufundiswa kwe-polyurethane ezinomsindo kusonjululiwe kumalunga nokuphucula nokufundiswa kwesicatshulwa. Imetales kunye nephesenti, iphi le nto, zizinto eziqukethweyo ezincedisiweyo ngomoya omncedisiweyo, xa kunye nepolyurethane ezinomsindo aziphuculeke kuhluke nokufundiswa kwaye lokhu kuyenza isenzo sokuqala. ngokuyinto ukuhlelo olunye kunye nezilungelo ezikweni apho imateriale aya kubekwa ngokushintsha okanye umsebenzi omncane wokuqala njengomthwalo wesayithi nokuziphatha kwesikhatsi esikhundleni sokugcina ngeendlu zemazibuko nokuziphatha kwisekhatsi somsebenzi esiqhathaniswe ngaphandle komsebenzi ongqamileyo.
Isixhenxe esithathu yokuba ipolimeri yepolyurethane iyakuthanda kakhulu nguqukethelana nobuncinci obucacileyo. Le ipolimeri yesemi yenza ukuba usebenzise ngazo zonke izinto eziningi ndawonye ezininzi ezindaweni eziningi. Ungaqhuba ngazo zonke izinto, lokhu kukho ekuvumela ipolimeri yepolyurethane yokugcina ukuze sebenze kwindawo eziningi. Ipolimeri yepolyurethane yasetyenziswa ngazo zonke iindlela eziningi, phakathi kokuba zizikhono zesicarha kusetyenziswa kwiindlela ezimbini nokulula amaxesha. Ipolimeri yepolyurethane yasetyenziswa ngazo zonke iindlela eziningi, le nto yokusetshenziswa kukho ingxenye elincinci lokuhlola kakhulu lesikompuni esiyenza lezi zinto nokuba ngoko kukho kukho indlela eyahlukene yokusetshenziswa.
Ukufunda ukuthi ngaphambili polyurethane inceda kanjani kube unomsebenzi ongqamathelakalo okungqoqwe. Iziphathanetho zakhe ezincedayo, ezindala, ezisibuyile kumthwalo nokuhlola izinkululo zihlala kwi-dokithabeni. Lolu hlobo lwe polyurethane luhluhlulekile ngoku lungayiphiwa ngemva kokuthi imali yaleyo amagama angazange akusetyenziswa. polyol kunye no-isocyanate lukho kungaba lokungcono ukuba isetshenziswa iphinde iphinde phakathi kwesikhashana esingafuneki ukusetshenziswa. Ngokugcina, polyurethane elidingwayo libonisa ukuthi ngenxa yokuba lingalibali, kungaqinisekisa ukubona kanye nokusetshenziswa. Nangona kunye nokuhlola kahle kwezinto ezincedayo, ngoko ke akuzange alandele kakhulu ngaphandle kokusebenzela. Ukufunda le nto lokungcono kuzoba kuhlala kakhulu ngokuthi izifundo zezikhundla zizofuneka zisetshenziswa ngokuphi polyurethane olungcede. Lokhu kuzoba ukuba zibeke amaxhobo amakhulu kunye nezinye izinto.
Ngokushesha lokho, kunezi zinto ezingcinane ezincedayo ezinikezela indawo yokuhlola kwezinto. Into engahlukileyo ngokuthi polyurethane encedayo ingavumelekanga ukuba ibuyiselwe. Lokhu tri thylene diamine ingxoxo enokwenzela ukuba aqhele ngaphandle kokuthi kufuneka, ukusuka kwisiseko esisetyenziselwe noma yonke into okufunekayo lokusebenza xa akukho indawo efuna ukubuyiselwa, ukuhlanganisa ukulimelwa komhlaba. Ukugcina umthombo wesithathu phambili yokuhlala ngokuphi ndawonye nokusetshenziswa kwezinto ezinethuthukileyo, ngoba ukugcina umthombo kunye nomhlaba ungene kuqala ukusetha isiphumo saso. Ukushintsha i-polyurethane elikhulu ligcinakala inkqubo yesixa lokuxhasa lokusebenza kwayo kwi-energi, eyayiqhuba ukuthi lizange libe ngokwesixa lokungena kwindawo yokuziphatha. Ngoko ke, i-polyurethane elikhulu ifanele kumikhampeki nokulima komhlaba.
