I-polyurethane foam yeyona into eqhelekileyo inokuthi ifakwe kwiindlela ezahlukeneyo, ukusuka kumgco, iindonga zokholwa kumasipala. Ii-additives ezisetyenzisiweyo kwinqanaba lepolyurethane foam kufuneka ayiphendulelo naphi na okanye ibe yinxalenye yesahluko, ukuze kufunyenwe isiphumo esilungileyo. Ukulingana kwe-polyurethane foam kunye nee-additives kuyinto ebalulekileyo ekubeni yinxalenye yokugcina, inkqubo kunye neemithetho yayo.

Ukulingana kweFoam kunye nee-Additives Ukufumana Iziphumo Ezilungileyo

Ukulingana kwegesi yepolyurethane ngezinto ezongeziweyo kuyiyo inkqubo ekubalulekileyo ekufuneni impendulo ephambili. Izingozi (ezilandelayo zingumthwalo, i-catalysts, i-surfactants kunye nezinyikithi zokuphazamisa umlilo) zibaluleke kakhulu kwinkqubo yokwenza igesi kwaye kwiimpawu zokugcina. Ngaphezu koko, kumangaliso ukulandela izinto ezongeziweyo ezingalingananga negesi ye-polyurethane ukuze akunakanyuswa indlela eyenziwa ngayo igesi enobumbane okanye ukuba akunciphise iindlela zocango, iimpawu zomthwalo, njalo njalo.

Ukukhetha Igasi Efanayo yePolyurethane NeeZinto Ezongeziweyo

Kukho amaxesha amaninzi aphinde afikelele ukuchaza igesi echanekileyo ye-polyurethane, kunye neezinto ezongeziweyo kwaye izinto eziphathekayo ezisetyenziswa kwiimfuno ezithile. I midi isocyanate ifomu efaneleyo, iinkcukacha zefomu efunekayo, iiparamitha zokuchazwa kwaye iindlela ezisetyenziswa ngazo zonke zibandakanya ekubeni kugunyazwe ifomu/ifihlo echanekileyo. Umzekelo, ukuba kukho inyaniso yokukhupha ngqo kufuneka, kungafuneki ukuba kusetyenziswe iifihlo ezifana nezibophezela izimbi kwaye ziqine zeziphumla. Ngokuphambene, ukuba ubuninzi kwaye iivali lefomu zililungiselelo, kungabandakanywa kwizixhobo zokwenza ubuninzi kwaye iifihlo ezibekwe kumfanekiso.

Ukusimisa Iinkcukacha Zefomu Ngeengcinga ZePolyurethane

Iifomu zePolyurethane ziyinxalenye enobulungiswa kwaye zingasetyenziswa njengefomu encinane ngapha kwegcinezelo elikhulu. Ukwahluka Kwepolyurethane Ukufumana Ifomu Eyangalanga amaphu zokungqinisekisa kufuneka kubizwe ngokucacileyo ukulinganisa kweengcinga ukuze kufumanke ifomu eqhelekileyo. Iinkcukacha zefomu yePolyurethane zingabuyiselwa ngokusebenzisa iingcinga ukuze zibe yinkimbinkimbi, zenzeke ngempazamo, okanye zinobuninzi kwaye zinobuthathaka.

Imfutshane Yobugcisa Bekhaya Ngokusebenzisa iPolyurethane - Iintsuku

Ukunceda kakhulu kwiimeko zokwenza i-polyurethane yenzelwa ngokukhetha ngempumelelo iingcingo ezifana neengcingo ezisetyenziswayo kwi-polyurethane. Kufuneka kuqwalaselwa nokuba ziphi na iinguqu ze-chemical structure zepolyurethane kunye neengcingo ukuze zibandakanye ngempumelelo. Ngaphezu koko, kucacile ukuba umphathi acacise ukuba iingcingo zibandakanya ngempumelelo nge-polyurethane ngokuphambela izahlulo eziphambili eziphambili phambi kokuba kwehlise ekunyuseni.

Izinto eziphambene kakhulu ngesiphumo se-polyurethane foam

Kukhona iintsontela ezimbalwa kwintonga yesifo sabathengi bepolyurethanes abafunayo ukuzibeka phantsi. I inja yokulapha kufuneka yenziwe ngexesha eliqinisekileyo elilungileyo ukuze kuthuthelwe ubungakanani bokhula kunye nokulungiswa kwefomu. Okwesibini, kufuneka i-polyurethane kunye neengcingo zihlambjwe kwaye zithunyelwe ngokuchanekileyo ukuze zifakelwe iimeko ezingcono zefomu.
