Tinowanzoona zvinhu zviviri izvi, nylon nepolyurethane, muzvigadzirwa zvakasiyana-siyana, kunyanya munyaya dzemakasta. Asi musiyano uripo pakati pazvo ndeupi, ndeupi une mashandiro ari nani? Ngationgororei pamwe chete.
Chekutanga, tinofanira kunzwisisa musiyano mukuru uripo pakati pezvinhu zviviri izvi. Zvichitaurwa zviri nyore, polyurethane chinhu chinopfava uye chakapfava, saka hachina ruzha rwakawanda uye hachina kukweshana kwakawanda. Izvi zvinoreva kuti ma polyurethane casters akanyarara pakushanda, asi anogona kusaramba kupera sema nylon casters.
Uye nylon chinhu chakaoma, chinodzivirira kukwesha zvakanaka. Saka kana uchida caster ine simba guru uye inodzivirira kukwesha, nylon casters inogona kunge yakakunakira!
Saka sei zvinhu zviviri izvi zvakasiyana kudaro? Kutaura zvazviri, zvese zvinobva pachimiro chazvo chemakemikari uye hunhu hwazvo. Polyurethane inogadzirwa nekuita polymerizing isocyanate ne hydroxyl compounds, uye ine simba rakanaka rekudzivirira mafuta, kusimba, kuramba kukwesha, kuramba kukwegura uye kunamira. Kune rumwe rutivi, nylon ine simba guru rekudzivirira kupisa, kuramba kuneta uye kuramba kukwesha, pamwe nesimba rakanaka remakanika uye kugadzikana kwezvikamu.
