Sihlala sibona ezi zinto zimbini, i-nylon kunye ne-polyurethane, kwiimveliso ezahlukeneyo, ingakumbi kwicandelo lee-casters. Kodwa yintoni umahluko phakathi kwazo, yeyiphi esebenza ngcono? Masizihlolisise kunye.
Okokuqala, kufuneka siqonde umahluko ophambili phakathi kwezi zinto zimbini. Ngamafutshane, i-polyurethane yinto ethambileyo ethambileyo, ngoko ke ayingxoli kakhulu kwaye inomngqushu omkhulu. Oku kuthetha ukuba ii-polyurethane casters azinamsindo xa zisebenza, kodwa zisenokungagugi njengee-nylon casters.
Kwaye i-nylon yinto eqinileyo, enokumelana nokukrweleka okuhle kakhulu. Ngoko ke ukuba ufuna i-caster enomthwalo omkhulu kunye nokumelana nokuguguleka, ii-caster ze-nylon zingakulungela ngakumbi!
Kutheni ke ezi zinto zimbini zahlukile kangaka? Enyanisweni, zonke zivela kwisakhiwo sazo seekhemikhali kunye neempawu zazo. I-Polyurethane yenziwa ngokupholisha i-isocyanate ngeekhompawundi ze-hydroxyl, kwaye inokumelana okuhle kweoyile, ukuqina, ukumelana nokukrweleka, ukumelana nokwaluphala kunye nokunamathela. Kwelinye icala, i-nylon inokumelana nobushushu okuphezulu, ukumelana nokudinwa kunye nokukrweleka, kunye namandla abalaseleyo oomatshini kunye nokuzinza kobukhulu.
