Sivame ukubona izinto ezimbili, inayiloni ne-polyurethane, emikhiqizweni ehlukahlukene, ikakhulukazi emkhakheni we-casters. Kodwa uyini ngempela umehluko phakathi kwazo, iyiphi esebenza kangcono? Ake sihlole ndawonye.
Okokuqala, sidinga ukuqonda umehluko oyisisekelo phakathi kwalezi zinto ezimbili. Kalula nje, i-polyurethane iyinto enwebekayo ethambile, ngakho ayinamsindo futhi inokungqubuzana okwengeziwe. Lokhu kusho ukuthi ama-caster e-polyurethane athule ngokusebenza, kodwa angase angakwazi ukumelana nokuguga njengama-caster enayiloni.
Futhi inayiloni iyimpahla eqinile, enokumelana okuhle kakhulu kokuhuzuka. Ngakho-ke uma udinga i-caster enomthamo omkhulu wokulayisha kanye nokumelana nokugqoka, ama-caster enayiloni angase afaneleke kakhulu kuwe!
Pho kungani lezi zinto ezimbili zihluke kangaka? Empeleni, konke kuvela ekwakhekeni kwamakhemikhali abo kanye nezakhiwo. I-polyurethane yenziwa nge-polymerizing isocyanate enezinhlanganisela ze-hydroxyl, futhi inokumelana okuhle nowoyela, ukuqina, ukumelana nokuhuzuka, ukumelana nokuguga nokunamathela. Ngakolunye uhlangothi, inayiloni inokumelana nokushisa okuphezulu, ukumelana nokukhathala kanye nokumelana nokuhuzuka, kanye namandla amahle kakhulu emishini nokuzinza kwe-dimensional.
