I-polyurethane caster yentsimbi luhlobo lwe-caster enezinto ze-polyurethane, ebotshelelwe kwi-cast iron core, i-steel core okanye i-steel plate core, ezolileyo, ezinobunzima obucothayo kwaye ezingabizi kakhulu, kwaye zifanelekile kwiindawo ezininzi zokusebenza.
Ngokwesiqhelo, ubukhulu bee-casters zemizi-mveliso buphakathi kwe-4 ~ 8 intshi (100-200mm), kwaye amavili e-polyurethane ngawona angcono. Amavili e-polyurethane anokumelana nokukrala okuphezulu, uluhlu olubanzi lokusebenza oluhlengahlengiswayo, iindlela ezahlukeneyo zokucubungula, ukusetyenziswa ngokubanzi, kunye nokumelana okuhle neoyile, i-ozone, ukuguga, imitha, ubushushu obuphantsi, njl.njl., ukungena kwesandi okulungileyo, amandla okuncamathelisa aqinileyo, ukuhambelana okuhle kwezinto eziphilayo kunye nokuhambelana kwegazi.
Ii-casters ze-polyurethane zibonakaliswa kakhulu zezi mpawu zilandelayo:
1. Uluhlu olukhulu lokusebenza oluhlengahlengiswayo. Ngokukhetha izinto eziluhlaza kunye nokulungisa ifomula, inokuba nokuguquguquka ngaphakathi koluhlu oluthile lotshintsho kwinani leempawu zokusebenza ezibonakalayo nezoomatshini, ukuhlangabezana neemfuno ezizodwa zomsebenzisi ekusebenzeni kweemveliso. Umzekelo, ii-polyurethane elastomers zinokwenziwa zibe ziirola zerabha eziprintwayo ezithambileyo kunye neerola zentsimbi eqinileyo ukuhlangabezana neemfuno zabasebenzisi abahlukeneyo.
2. Ukumelana nokukrala okuphezulu. Xa kukho amanzi, ioyile kunye nezinye iimeko zokusebenza ezimanzisayo, ukumelana nokukrala kwee-polyurethane casters kuphindwe kaninzi ukuya kumaxesha amaninzi kunoko kwezixhobo zerabha eziqhelekileyo.
3. Iindlela ezahlukeneyo zokucubungula kunye nokusetyenziswa ngokubanzi. I-polyurethane elastomer inokubunjwa ngenkqubo yokwenza iplastiki, ukuxuba kunye ne-vulcanizing (ibhekisa kwi-MPU); inokwenziwa ibe yirabha engamanzi, ukubumba okanye ukutshiza, ukubumba imbiza kunye nokubumba i-centrifugal (ibhekisa kwi-CPU); inokwenziwa ibe zizinto ezi-granular kwaye ibunjwe nge-injection, extrusion, calendering, blow molding kunye nezinye iinkqubo (ibhekisa kwi-CPU).
4. Ayimelani neoyile, i-ozone, ukwaluphala, imitha, ubushushu obuphantsi, isandi esifanelekileyo, amandla okuncamathelisa aqinileyo, ukuhambelana kakuhle kwezinto eziphilayo kunye nokuhambelana kwegazi.
Nangona kunjalo, ii-polyurethane elastomers zineengxaki ezithile, ezinje ngobushushu obuphezulu bendalo, ukumelana nobushushu obuphezulu ngokubanzi, ingakumbi ukumelana nokufuma nobushushu, ukungamelani nezinyibilikisi ezinamandla ze-polar kunye ne-acid enamandla kunye ne-alkali media.
