Yintoni iPolyurethane?
Luhlobo oluthile lwepolymer, imathiriyeli eyomeleleyo esiyisebenzisayo ukwenza izinto ezahlukeneyo, ukusuka kwimihla ngemihla. Ungayifumana kwizinto ezifana nokugquma kwendlu yakho, ifanitshala onokutshona kuyo, nakwiindidi ezithile zempahla. Ngoko ke sihamba njani ngokwenza le plastiki ikhethekileyo? Ipolyurethane: Oku kwenziwa ngokudibanisa iikhemikhali ezimbini eziphambili: isocyanate kunye nepolyol. Ke xa ezi khemikhali zimbini zidibana, ziyasabela kwaye zenze iibhondi ezibizwa ngokuba zii-urethane bonds. Yinkqubo ebalulekileyo yokwakha dibutyltin dilaurate catalyst polyurethane. Emva koko sifuna into ekhethekileyo yokunceda ukutsiba-ukuqalisa le mpendulo ukuba yenzeke ngokukhawuleza kwaye kulula - into encedayo.
IiCatalysts zokuHlangula kwiPolyurethane
Xa kuziwa ekwenzeni i-polyurethane, ii-catalysts zibaluleke kakhulu. Basebenza njengabancedi abancinci abanceda ukuba izinto zisabele ngokukhawuleza kunye nomnye umchiza. Ukuba sikhetha i-catalyst efanelekileyo, sinokuvelisa iimveliso eziphezulu kakhulu. Kwimeko xa ngempazamo sisebenzisa izinto ezibi okanye ezikumgangatho ophantsi, sinokugqiba nge-polyurethane engomelelanga, ilula kakhulu, okanye engabubambeli ubushushu. Nangona kunjalo, ukusetyenziswa kwee-catalysts ezilungileyo kunokunika i-polyurethane amandla ayo kunye nokusebenza ngokubanzi, yingakho ingasetyenziselwa iinjongo ezininzi ezahlukeneyo.
IiCatalysts: Imveliso yokuKhawuleza ngokukhawuleza
Yonke inkqubo yokwenza i-polyurethane ingenziwa kwakhona nge-catalyst efanelekileyo-iyenza ikhawuleze kwaye isebenze ngakumbi kuneendlela eziqhelekileyo. Oku kuthetha ukuba sinokuvelisa iimveliso ezifana ne-polyurethane foam ngexesha elincinci. Oku kwenza ukuba iifektri zikhuphe iimveliso ezininzi ngexesha elifutshane xa impendulo isenzeka ngokukhawuleza Oku kulungile kwishishini kuba linokuhlala linikezela ngeemveliso ezininzi kubathengi ngaphandle kokulibaziseka.
Indlela yokufumana uninzi lwePolyurethane?
Nge-catalyst efanelekileyo, sinokukhulula amandla apheleleyo i-organotin compound i-polyurethane. Oko kuthetha ukuba iipropati zayo zinokutyhilwa ngakumbi, kwaye sinokuyisebenzisa kwiimeko ezininzi. Iicatalysts ezomelele kwaye zilunge kakhulu zinokusetyenziselwa ukuvelisa izinto eziyimfuneko kwizithuthi, ezilolo hlobo zomelele kwaye zifuna ukuthwala uxinzelelo olugqithisileyo. Ukongeza, sinokunciphisa ungcoliseko kunye nenkunkuma kwimveliso ngokusebenzisa nje inkqubo efanelekileyo ye-catalyst. Linyathelo elibalulekileyo ukwenza iinkqubo zethu zokuvelisa zibe luhlaza kwaye zigcineke ngakumbi kuMhlaba.
Ukuqhubela phambili kwiTekhnoloji yeCatalyst
Kukho umyalezo othe kratya kwihlabathi lezinto ezincedayo kwaye usebenza kwinqanaba eliphezulu ngokuhamba kwexesha. Inkqubela phambili yamva nje yetekhnoloji, nangona kunjalo, ikhokelele kwi-catalysts kunye nokusebenza kakuhle kunye namaxesha amafutshane okuphendula. Kubekho uphuhliso lwamva nje noluthembisayo kwesi sithuba, njengokusebenzisa i-metal-organic frameworks (MOFs) ukuvelisa i-polyurethane. Ezi ntlobo zitsha zee-catalysts zinokusinceda senze i-polyurethane ngendlela esebenza ngokufanelekileyo.
Iingcali zakho kwiiCatalysts zePolyurethane-Lingshi
U-Lingshi unamava kakhulu kuphando kunye nophuhliso lwe-polyurethane catalyst. Ngokuzinikezela ekunikezeni izisombululo ezingcono kwiimfuno zomenzi, iimveliso zethu zithenjwa kwihlabathi jikelele. Iilebhu zethu zenza umgudu omkhulu ekuphuhliseni iintlobo ezininzi zee-catalysts ezilungele usetyenziso olwahluke kakhulu. Siqeqesha umgangatho ophezulu oluhlaza kunye neemveliso ezinempilo kubavelisi.
isiphelo
Ngamafutshane, ukhetho lwe-catalyst lubalulekile ekuveliseni umgangatho dibutyltin kunye ne-polyurethane. Ii-catalysts ezifanelekileyo zinokugcina ixesha kunye nemali kunye nenkcitho encinci kwinkqubo. Kwindima yakhe njengeqabane elithembekileyo, uLingshi uzibophelele ekuziseleni itekhnoloji ye-catalyst ephucukileyo ukwenza amandla apheleleyo e-polyurethane-imveliso ezomeleleyo, ezikhaphukhaphu, nezihlala ixesha elide, kwaye ezinokusetyenziswa kwizicelo ezininzi.
