Isu tinowanzoona zvinhu zviviri, nylon uye polyurethane, muzvigadzirwa zvakasiyana-siyana, kunyanya mumunda wemakasi. Asi chii chaizvo chiri musiyano pakati pavo, ndeupi ane kuita kuri nani? Ngationgororei pamwe chete.
Chokutanga pane zvose, tinofanira kunzwisisa musiyano mukuru pakati pezvinhu zviviri izvi. Zvichitaurwa zviri nyore, polyurethane isimbi yakapfava iyo yakapfava, saka haina ruzha uye ine kukwesha kwakawanda. Izvi zvinoreva kuti ma polyurethane casters akanyarara mukushanda, asi anogona kunge asina kupfeka-kusagadzikana seanokanda naironi.
Uye nylon chinhu chakaoma, icho chine yakanaka kwazvo abrasion resistance. Saka kana iwe uchida caster ine yakakwira mutoro uye kupfeka kuramba, nylon casters inogona kunge yakakukodzera iwe!
Saka nei zvinhu zviviri izvi zvakasiyana? Chaizvoizvo, zvese zvinobva kune yavo yemakemikari chimiro uye zvimiro. Polyurethane inogadzirwa ne polymerizing isocyanate ine hydroxyl makomisheni, uye ine yakanaka mafuta kuramba, kuoma, abrasion kuramba, kuramba kuchembera uye kunamatira. Nylon, kune rumwe rutivi, ine yakanyanya kupisa kupisa, kuneta kuramba uye abrasion kuramba, pamwe neakanakisa emuchina simba uye dimensional kugadzikana.
