Sihlala sibona izinto ezimbini, i-nylon kunye ne-polyurethane, kwiimveliso ezahlukeneyo, ngakumbi kwintsimi ye-casters. Kodwa yintoni kanye umehluko phakathi kwabo, ngubani onokusebenza okungcono? Masiphonononge kunye.
Okokuqala, kufuneka siqonde umahluko osisiseko phakathi kwezi zixhobo zimbini. Ukubeka nje ngokulula, i-polyurethane yimathiriyeli e-elastiki ethambileyo, ngoko ayinangxolo kwaye ine-friction eninzi. Oku kuthetha ukuba iicaster ze-polyurethane zithe cwaka xa zisebenza, kodwa zisenokungaxhathisi njengezokhasa zenayiloni.
Kwaye inayiloni yinto enzima kakhulu, enokumelana okuhle kakhulu kwe-abrasion. Ke ukuba ufuna i-caster enomthamo omkhulu womthwalo kunye nokumelana nokunxiba, iicaster zenayiloni zinokukufanelekela ngakumbi!
Kutheni ke ezi zinto zimbini zahluke kangaka? Ngokwenyani, zonke zivela kulwakhiwo lwazo lweekhemikhali kunye neempawu. I-Polyurethane yenziwe nge-polymerizing isocyanate kunye neekhompawundi ze-hydroxyl, kwaye inokumelana ne-oyile elungileyo, ukuqina, ukuxhathisa kwe-abrasion, ukumelana nokuguga kunye nokubambelela. Inayiloni, kwelinye icala, inokumelana nobushushu obuphezulu, ukumelana nokudinwa kunye nokumelana ne-abrasion, kunye namandla abalaseleyo omatshini kunye nokuzinza komda.
