Kwizakhiwo zanamhlanje, ukuhombisa umgangatho akusiyonto nje yobuhle, kodwa kukwanelisa neemfuno ezibalulekileyo zokusebenza. Njengohlobo olutsha lwezinto zokuhombisa umgangatho, umgangatho we-polyurethane usebenza kakuhle kwaye usetyenziswa ngeendlela ezahlukeneyo.
Eli nqaku liza kukwazisa ngeempawu, iingenelo kunye neemeko ezifanelekileyo zomgangatho we-polyurethane.
Okokuqala, imigangatho ye-polyurethane izinzile kwaye ihlala ixesha elide. Isebenzisa i-polyurethane resin njengesixhobo esisisiseko kwaye yenziwe ngenkqubo ekhethekileyo. Imigangatho ye-polyurethane inokumelana nokuguguleka okugqwesileyo kunye nokumelana nokugqwala ngamakhemikhali. Ingamelana nokuguguleka kwezinto zangaphandle ezifana neoyile, i-asidi kunye ne-alkali, kwaye igcine ubuhle bomgangatho ixesha elide.
Kwangaxeshanye, imigangatho ye-polyurethane inokumelana noxinzelelo oluphezulu kunye nokuguguleka, inokumelana nokusetyenziswa ngamandla aphezulu, ayichaphazeleki lula kukuqhekeka okanye kukonakala, kwaye yandisa ubomi bomgangatho ngokufanelekileyo.
Okwesibini, imigangatho ye-polyurethane ineempawu ezilungileyo zokungatyibiliki kunye nokhuseleko. Umphezulu womgangatho we-polyurethane usebenzisa unyango olukhethekileyo lokungatyibiliki, olunokubonelela nge-coefficient elungileyo yokungqubana kunye nokunciphisa umngcipheko weengozi zokutyibilika xa abantu behamba. Oku kwenza imigangatho ye-polyurethane isetyenziswe kakhulu kwiindawo ezifuna iindawo zokungatyibiliki, ezinje ngeeworkshops zasefektri, iipaseji zesibhedlele, ii-gymnasiums, njl.njl.
Ukongeza, imigangatho ye-polyurethane ikwanazo neempawu ezinobuhlobo nokusingqongileyo. Isebenzisa ifomula engenaso isinyibilikisi, ayinazo naziphi na izinto eziyingozi, kwaye ayinangcoliseko okanye ingozi emzimbeni womntu nakwindalo esingqongileyo. Ngexesha lokusetyenziswa, imigangatho ye-polyurethane ayizukuvelisa iigesi eziyingozi ezifana ne-formaldehyde, ikhusela ngokufanelekileyo umgangatho womoya wangaphakathi kwaye ihlangabezana neemfuno zokhuseleko lokusingqongileyo zezakhiwo zanamhlanje. Kwiimfuno ezahlukeneyo zeendawo, imigangatho ye-polyurethane inokwenziwa ngokwezifiso ngokweemeko zokwenyani. Inokukhetha imibala eyahlukeneyo kunye nobume ukuze ihlangabezane neemfuno zokuhombisa ezenzelwe wena.
Ukwakhiwa komgangatho we-polyurethane kulula kwaye kuyakhawuleza, kwaye akudingi kunakekelwa nokugcinwa ixesha elide, nto leyo egcina ixesha kunye neendleko kakhulu. Ngamafutshane, umgangatho we-polyurethane uye waba lukhetho olufanelekileyo lokuhombisa umgangatho kwizakhiwo zanamhlanje ngenxa yokuqina kwawo okuqinileyo, ukhuseleko olungatyibilikiyo kunye nokusebenza okunobuhlobo nokusingqongileyo. Nokuba yindawo yefektri, isibhedlele, ibala lemidlalo okanye indawo yorhwebo, umgangatho we-polyurethane unokukunika izisombululo zomgangatho ezintle, ezisebenzayo nezihlala ixesha elide.
