Badanaa macaamiishu waxay na weydiiyaan casters-ka polyurethane-ka ee la dhigay muddo dheer, gabowga ayaa dhici doona, si fudud loo jebin karo iyo ifafaale kale, dhab ahaantii, tani ma aha dhibaato caster ah, taas oo ah dhacdo caadi ah.
Marka hore, sababaha gabowga ee polyurethane caster
Sababaha gabowga ee polyurethane caster-ka way kala duwan yihiin. Guud ahaan, sababaha ugu waaweyn ee gabowga polyurethane caster-ka waxaa ka mid ah oksaydheynta, shucaaca ultraviolet-ka, qoyaanka, heerkulka sare, heerkulka hooseeya, dareereyaasha kiimikada iyo arrimo kale oo deegaanka ah, iyo sidoo kale silsiladda molecular-ka polymer-ka ee qaab-dhismeedkeeda iyo xasilloonida kiimikada iyo arrimo kale.
Marka labaad, saameynta gabowga ee polyurethane caster
Da'da kabka polyurethane, sifooyinka jireed iyo kuwa kiimikada ayaa isbeddeli doona, taasoo u muuqan doonta midab madow, dildilaac dusha sare ah, hoos u dhac adkaysi, iyo hoos u dhac dabacsanaan ah. Iyadoo ay sii xumaanayso heerka gabowga, waxqabadka kabka polyurethane ayaa si tartiib tartiib ah u waayi doona shaqada, taasoo ugu dambeyntii horseedi doonta guuldarro agab. Codsiyada wax ku oolka ah, sida qalabka shaabadaynta dhismaha, alaabada maqaarka macmalka ah, kuraasta baabuurta iyo meelaha kale, kabka polyurethane ee gaboobay waxay horseedi karaan khataro ammaan oo suurtagal ah.
Saddexaad, haddii gabowga polyurethane uu horseedi doono jilcinta walxaha
Ka dib marka uu gaboobayo qalabka polyurethane, adkaanta iyo dabacsanaanta walaxda ayaa yaraan doonta, taasoo keeni karta jilcinta walaxda, laakiin tani maaha habka kaliya ee lagu muujiyo gabowga. Tusaale ahaan, hoos u dhaca sifooyinka cadaadiska ee qalabka polyurethane ayaa laga yaabaa inuu keeno isbeddel ku yimaada walaxda xoogga leh. Dabcan, tilmaamayaasha waxqabadka jireed sida adkaanta iyo dabacsanaanta qalabka polyurethane ayaa isbeddela ka hor iyo ka dib gabowga, taas oo ah mid ka mid ah tilmaamayaasha ugu muhiimsan ee heerka gabowga walaxda.
