Atlanta, GA - kubva munaGunyana 30 kusvika Gumiguru 2, The Omni Hotel paCentennial musangano weCentennial musangano, achiunza pamwe chete nyanzvi uye nyanzvi dzinobva kuPolyurethane indasitiri pasi rese. Yakarongeka neAmerican Chemistry Council yePolyurethanes Indasitiri (CPI), musangano unovavarira kupa chikuva chezvidzidzo zvezvidzidzo uye kuratidzira zvinowanikwa muPolyurethane Chemistry.

Polyurethanes anozivikanwa seimwe yezvinhu zvakanakisa zvepurasitiki zviripo nhasi. Zvivakwa zvavo zveMakemikari zvinovatendera kuti vave vagadziriswe kune yakasarudzika zviitiko, vachigadzirisa matambudziko akaoma uye kuumbwa mumhando dzakasiyana siyana. Uku kuchinja uku kunowedzera zvese zviri zviviri maindasitiri uye vatengi zvigadzirwa, kuwedzera nyaradzo, kudziya, uye kuve nyore kune hupenyu hwezuva nezuva.

Kugadzirwa kwePolyurethanes kunosanganisira maitiro emakemikari pakati pePolyols Kusiyana-siyana kwevanowanikwa diisocyanates uye polyls kunoita kuti vagadziri vagadzike panyama yezvinhu zvakagadziriswa kuti zvikumbiro, kugadzira polyurethanes zvinoshamisa maindasitiri akawanda.

Polyurethanes ari ubiquitous muhupenyu hwazvino hupenyu, inowanikwa mune dzakasiyana siyana zvigadzirwa kubva pamattres uye zvigadziko kune zvinhu zvekushandisa, zvimiro zvemvura, uye pendi. Ivo zvakare vanoshandiswawo muEurable Elastors, senge so roller blade mavhiri anochinjika, akapfava anochinja-foam matoyi, uye elastic fibers. Kuvapo kwavo kwakapararira kunosimbisa kukosha kwavo mukuwedzera chigadzirwa kuita uye kunyaradza kwevatengi.

Chemistry kuseri kwePolyurethane kugadzirwa kunosanganisira zvinhu zviviri zvakakosha: methlene diphenyl diisocyanate (mdi) uye toluene diisocyanate (TDI). Iyi mishonga inowana nemvura munzvimbo yekugadzira yakasimba inert polyureas, kuratidza zvinowanika uye kushandurwa kwePolyurethane chemistry.

Iyo 2024 polyurethanes technical musangano unoratidza zvikamu zvezvikamu zvakagadzirirwa kudzidzisa vaperemberi pakufambira mberi mumunda. Nyanzvi dzinokurukura zvinobuda zvichibva zvinobuda, zvinoshandiswa zvinosimudzira, uye ramangwana rePolyurethane tekinoroji, vachipa ruzivo rwakakosha kune venyamo dzemaindasitiri.

Sezvo musangano wacho unosvika, mutori vechikamu anokurudzirwa kuti aite vezera, govana ruzivo, uye ongorora mikana mitsva mukati mePolyurethane chikamu. Chiitiko ichi chinovimbisa kuve kuungana kwakakosha kune avo vanobatanidzwa mukuvandudzwa uye kushandiswa kwezvinhu zvePolyurethane.
