Yakashandurwa polyurethane zvisimbiso ndeye yakanakisa yekuvharisa zvinhu zvine yakanakisa kuramba kupfeka, ngura uye tembiricha yakakwira uye inoshandiswa mumhando dzakasiyana dzemaindasitiri ekushandisa.Ichi chinyorwa chinotsanangura maitiro ekutanga, nzvimbo dzekushandisa uye zvakanakira zvakashandurwa polyurethane zvisimbiso.Zvisimbiso zvinonziwo zvisimbiso kana zvisimbiso zvemafuta, inoumbwa nechikamu chimwe kana akati wandei echivharo chakaita semhete, chakamisikidzwa mugomba, chine seti yemhete, uye imwe seti yemhete kana gaskets kusangana kana kuumba yakamanikana labyrinth gap, tamba. basa rekuparadzanisa mafuta uye gasi remvura, kudzivirira kupfachukira kwemafuta kana kuburikidza uye nekupinda zvinhu zvekunze.Panguva imwecheteyo, inogona zvakare kutakura kudzvanywa, mukati meimwe nhanho ine mbiri mbiri yekutakura kumanikidza uye kuisa chisimbiso.Yakashandurwa polyurethane zvisimbiso, ine kusapfeka-resistant, oiri, asidhi, ozone, kuchembera, yakaderera tembiricha, kubvarura, kukanganisa uye humwe hunhu, inoshandura polyurethane zvisimbiso zvinotakura mutoro wekutsigira, inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana.Muchidimbu, zvisimbiso zvakashandurwa zvepolyurethane zvine zvakawanda zvakanakira uye zvinogona kushandiswa zvakanyanya munzvimbo dzakasiyana siyana dzeindasitiri.Naizvozvo, pakusarudza chinhu chekuisa chisimbiso, yakashandurwa polyurethane zvisimbiso isarudzo yakanaka.
Kubudirira kwepolyurethane sechisimbiso kwakauya mukutanga kwema1980, apo vazhinji vevagadziri vakagadzira polyurethane mbishi zvinhu zvainyanya kushingirira kuhydrolysis.Zvinhu zvitsva izvi zvakagadzira zvisimbiso zvepolyurethane zvakaramba zvichichinjika pakumanikidzwa kukuru uye kusvika +110 ° C, zvichiwana kuita kwekuvhara zviri nani uye hupenyu hurefu hwekushanda kupfuura yekutanga polyurethane (iyo yaingoshingirira kutonhora kwakanyanya kwe +80 ° C).Mhedzisiro iyi inovhura musuwo we hydraulic application mumakina enhare.
