polyurethane semi rigid self skinning foam release agent
Umphawuli wokulayisha wefofomu lesiPolyurethane semi rigid self skinning yonke inani loluhle olungakhetho olukhangelwe ngokupheleleyo ukwenza uphumulo okulondoloziwe kwekomponyenti ze-foam lepolyurethane. Ukufakelwa kokuthi lokhu luhlakaniphi lalokhu kulula imibhalo emikhono ngefofomu elandelayo, ukusureka nokususa amaxesha ngokushesha ngendlela enhle ngaphandle kokubhedekisa ubunzima bokwesayithi. Umphawuli wokulayisha wenze ikheli lemkhondo yokugcina esihlanganisiwe ngokuphela nokubuyelekiswa nenkqubo yakho ye-mold, ukuze zikhona izinsuzo ezilondoloziwe zokulayishwa ngaphandle kwezinye iindlela zokusebenza. Ingxenye yayo iyakhiwe ngokupheleleyo ukuba isebenza nge-foam lesemi rigid self skinning apho kuzwangene amaxesha angaphandle nokuxhasa lokuncedisiwe ngokupheleleyo. Isibonelo sangcono sasemphathisweni asikhethe umthakathi wesayithi nokuba akhetha ukubhedekisa sayo, kungene ukusuka komkhono omkhulu wokuqala kwe-foam nokubuyelekiswa ngenxa yokuba lokhu lokulandelayo lavela ngokupheleleyo. Iphawuli ifanele ngokupheleleyo ngazo zonke iimateriali yesayithi, phakathi kwalumiyo, isteel kunye ne-composite materials, uzama ukubuyelekiswa kwiindawo zokusebenza ezidingekile ezi 20-80°C. Lolu hlobo olungavumelekanga lokulayisha ulandelayo ususa amaxesha amaningi, ukusura ukubuyelekiswa kumva kwamaxesha amacabango amaningi, ukususa uphumulo kumva kwezinto ezinomsindo njengomphawuli wokulingana ngekomponyenti zakahle ekufundweni lakahle, amaxesha amaduda kunye nokusebenza kwezinto ezininzi zokusebenza.
