Sivame ukubona izinto ezimbili, i-nylon kanye ne-polyurethane, emikhiqizweni eyahlukahlukene, 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 ethambile futhi ethambile, ngakho ayinomsindo kakhulu futhi inokungqubuzana okukhulu. Lokhu kusho ukuthi ama-polyurethane casters athule kakhulu lapho esebenza, kodwa angase angagugi njenge-nylon casters.
Futhi i-nylon iyinto eqinile, enokumelana okuhle kakhulu nokuguguleka. Ngakho-ke uma udinga i-caster enamandla okuthwala umthwalo omkhulu kanye nokumelana nokuguguleka, ama-caster e-nylon angakufanelekela kangcono!
Pho kungani lezi zinto ezimbili zihluke kangaka? Empeleni, konke kuvela esakhiweni sazo samakhemikhali kanye nezakhiwo zazo. I-polyurethane yenziwa ngokupholisha i-isocyanate ngamakhemikhali e-hydroxyl, futhi inokumelana okuhle kwamafutha, ukuqina, ukumelana nokuklwebheka, ukumelana nokuguga kanye nokunamathela. Ngakolunye uhlangothi, inayiloni inokumelana nokushisa okuphezulu, ukumelana nokukhathala kanye nokuklwebheka, kanye namandla amahle kakhulu okusebenza kanye nokuzinza kobukhulu.
