Iron core polyurethane caster rudzi rwecaster ine polyurethane, yakabatana ne steel core, steel core kana steel plate core, iyo yakanyarara, inorema zvishoma uye isingadhuri, uye yakakodzera nzvimbo zhinji dzekushanda.
Kazhinji, saizi yema "casters" emuindasitiri iri pakati pe 100-200mm (4~8 inches), uye mavhiri e polyurethane ndiwo akanakisa. Mavhiri e polyurethane anodzivirira kukwesha zvakanyanya, mashandiro akasiyana-siyana anogadziriswa, nzira dzakasiyana dzekugadzirisa, kushanda kwakakura, uye kudzivirira mafuta, ozone, kukwegura, mwaranzi, tembiricha yakaderera, nezvimwewo, kupenya kweruzha kwakanaka, simba rakasimba rekunamira, kubatana kwakanaka kwemuviri uye kuenderana neropa.
Mapombi epolyurethane anonyanya kuratidzwa nezvinhu zvinotevera:
1. Kugona kukuru kunogadziriswa. Kuburikidza nekusarudza zvinhu zvakagadziriswa uye kugadzirisa fomura, zvinogona kuchinja-chinja mukati mehuwandu hwakasiyana hwekuchinja muzviratidzo zvemuviri uye zvemakanika, kuti zvisangane nezvinodiwa nemushandisi pakushanda kwezvigadzirwa. Semuenzaniso, ma elastomer e polyurethane anogona kugadzirwa kuita ma roller erabha anodhindwa zvinyoro nyoro uye ma roller esimbi yakaoma kuti zvisangane nezvinodiwa nevashandisi vakasiyana.
2. Kudzivirira kukuru kwekukwesha. Kana paine mvura, mafuta nezvimwe zvinhu zvinonyorovesa, kuramba kwepolyurethane casters kunowedzera kakawanda kusvika kakawanda kupfuura zvinhu zverabha zvakajairika.
3. Nzira dzakasiyana-siyana dzekugadzirisa uye kushandiswa kwakakura. Polyurethane elastomer inogona kuumbwa nekuita plasticizing, mixing and vulcanizing process (zvinoreva MPU); inogonawo kugadzirwa kuita liquid rabber, casting molding kana spraying, potting uye centrifugal molding (zvinoreva CPU); inogonawo kugadzirwa kuita granular material uye kuumbwa ne injection, extrusion, calendering, blow molding nedzimwe nzira (zvinoreva CPU).
4. Haipindi mafuta, ozone, kukwegura, mwaranzi, tembiricha yakaderera, ruzha rwakanaka, simba rakasimba rekunamira, kuenderana kwakanaka kwehupenyu uye kuenderana kweropa.
Zvisinei, ma polyurethane elastomers ane zvimwe zvaasingade, zvakaita sekupisa kwakanyanya, kupisa kwakanyanya, kunyanya kupisa kwakanyanya, kusingadziviriri hunyoro nekupisa, kusingadziviriri kuzvinhu zvine simba zve polar solvents uye acid ne alkali media.
