Ngubani i-Polyurethane?
Yintoni ngokushesha umbhatho, umthombo omkhulu wamaxesha esethweni sasetyenziswa ukusetshenziswa kwezinto eziningi, kusukela zemvelo. Ungathola kwiintshango zomdlo zewudi, amagubho apha akufuneka ukuhlala khona, kunye nezinye izinto zokuphila. Ngoko ke, nguyiphi indlela yesetshenziswa kwezi zinto eziphakamisayo? I-Polyurethane: Zisetshenziswa ngokugabuliswa kwezimbali ezimbini ezikhoyo: i-isocyanate kunye no-polyol. Ngakwesobizo, lento abebenza kunye nokuba zizama ukufika, bazama ukubona isiqephu esinezintlango ezinamandla ezininzi ezinamandla ezinamandla ezithileyo. Kutheni kukholelwa kakhulu lokusetshenziswa dibutyltin dilaurate catalyst polyurethane . Ngokuqondile, singafuna into engaphakathi yokuthatha le nto yokuba kuhle ngenkinga - umphumeleli.
Amphumeleli angamandla ukusetshenziswa kwePolyurethane
Xa kudumelelwa ukubuyisela i-polyurethane, iicatalyst ziqinisekile kakhulu. Zaziqale ngokwesonto ezifundekayo eziqhelekanga amanxaso ukuba zitye ngeendawo ezintsha nokulula nokufunda ngenye indawo yamancazelo. Ukuba sithetha icatalyst esibonakalisiyo, singabuyiselanga amaxwebhu okungaphezu kakhulu. Ngoku elisha kunokuba sithiwe icatalyst engapheliyo okanye engasemntlaneni, singacitshelanga ipoliyuritan yiyo engenisiso, ingeyiphi ndawo, okanye ayiqonda imfutso weheat. Kodwa, uphinda usebenzisa icatalyst esibonakalisiyo, liphinde liziphindaphinda ukuba ipoliyuritan yayiyenzeka kwaye nokugcina kwesikhatsi sesimo, lokuhlola ukuba lingasebenzise ngamandla eminingi.
AmaCatalyst: Ukuphucula Kwesicwangciso
Yomgca ophambili wokubhala i-polyurethane iyafuneka kufakwe ngenqanawe yezilungileyo - ifanele kulapho kube ngqukukeneyo kunye nehlukene ngaphezulu kweguqulelo ezintathu. Ukuthi ingaba sibhale amagama angaphandle komoya. Lokhu kuvavanyelwa ukuba singabhalise amagama ngemva kokucabanga lokho kuyenzelwa ngqukukeneyo Lolu hlobo lomgca alingayazi ukuba yintoni ngqo.
Ngubani ukuya kuqinisekisa Emgca Ewuphi Wesi Polyurethane?
Ngenqanawe yenziwe, sizoba sithumele amandla ephakathi isikompuni Sesi-Organo-tin ipoliyurithane. Ukuthi amandla akho akuyinto okungakwazi ukubonwa ngokupheleleyo, futhi sifuna ukusetyenziswa kwisezinye izindawo. Izikatilitha ezinomoya ezibuzayo ezisebenza kakhulu zisetshenziswa ukusetshenziswa izicatshulenti ezidingekileyo ezidinga ukuba zisize ukukhangelana nesizathu esingaphambili. Ngokushesha, singakwazanga ukubonisa isikhathi sokuphucula nokusebenzela emfutheleleni ngokusetshenziswa ukuphucula elikhoyo lokusebenza. Yilandelayo ingxenye yokuhlala yezinto ethunyelwe liphakamise imigomo yetyala ukuba yinhloko yesihlanu kunye neziqondiso.
Ukuphumelela Kwemibiko Yezikatilitha
Kuneenketho ezininzi ephakanyiswayo kwendawo yezikatilitha kunye nokuba kufuneka kube ngokwesaba lwesikhatsi. Okungaphezulu, ukuphumelela kokusebenza komthebo, kodwa kukholelwa amanani amahhovu amanani amahhovu (MOFs) ukusetshenziswa ipoliyurithane. Izikatilitha ezintsha zisetshenziswa ukusetshenziswa ipoliyurithane ngokupheleleyo.
Izakhiwisi zakho ezilungileyo kwiPolyurethane Catalysts – Lingshi
Lingshi ingaphambili ngokulula kuhle kufunda nokuthuthukisa lokuhlola polyurethane catalyst. Ngenkatho yokugcina ukuthi uzohamba ngezinye izinhlelo zokuthi, amagama anguqinisekiswa phakathi kwesicwangciso sesithuba. Amalabha akho azifuna ukuthiwe kakhulu ukufika lokuhlola amanani apho ahlala kudifasini. Siyazibiza amagama angomoya omphumeleyo kunye nokuthi iimeko yabo yayaziwayo.
Ukuphawula
Ngoku, ukukhetha kwezakhiwo singahlanganisa ngempumelelo dibutyltin nompumelelo we-polyurethane. Izakhiwo ezikhona zizihlabeleka isikhatsi kunye nokuphela okususa imali ngokubhekene nesiphumo esidingayo. Ngokusebenza komkhosi wakhe wesithandwa, Lingshi uhlobene ngenxa yokuba uyayiqhathanisa ukuthiwe kakhulu lokuhlola polyurethane — amagama angumthombo omkhulu, ongaphansi kunye nokuyenza kakhulu, kunye nokuzigcina kakhulu, kunye nokuba zisetyenziswa kwindaweni eziyi-nyaniso.
