Kushandiswa kwe polyurethane

Polyurethane inogona kushandiswa mukugadzirwa kwepurasitiki, rabha, fiber, yakaoma uye inoshanduka foams, adhesives uye coatings, etc. Inogona kushandiswa munzvimbo dzakasiyana-siyana dzehupenyu hwevanhu uye ine zvakasiyana-siyana zvekushandisa.

1. Polyurethane furo:

Yakakamurwa kuita yakaoma polyurethane furo, semi-yakaomarara polyurethane furo uye inochinjika polyurethane furo.Rigid polyurethane foam inonyanya kushandiswa pakuvaka zvigadziriso zvekupisa, zvigadziriso zvemafuta (pombi zvivakwa, nezvimwewo, kupisa kwemafuta uye kushandiswa kwemazuva ese) (mibhedha, sofa, nezvimwewo, matiresi, mafiriji, maair conditioner, nezvimwewo, insulation layers, uye surfboards, etc. core materials, uye Transportation (mota, ndege, njanji motokari, makushion, sirin'i nezvimwe zvinhu).

2. Polyurethane elastomer:

Polyurethane elastomer ine mabhenefiti esimba rakanaka rekusimba, simba rekubvarura, kurwisa kwekuita, abrasion kuramba, kuramba kwemamiriro ekunze, hydrolysis kuramba, mafuta kuramba uye zvichingodaro.Inonyanya kushandiswa kupfekedza zvinhu (zvakadai sekudzivirira hose, washers, matai, rollers, giya, pombi, nezvimwewo), insulators, manyatera eshangu, uye matai akasimba.

3. Polyurethane isina mvura zvinhu:

Polyurethane isina mvura zvinhu zviri nyore kushandisa.Inogona kusanganiswa pane saiti uye kuporeswa neyakajairwa tembiricha uye humidity mushure mekuputira, uyezve isina mvura layer isina seams, rubber elasticity uye kuita kwakanaka kunogona kuwanikwa.Uye nyore kugadzirisa mushure mekukuvara.Inowanzo shandiswa semidziyo yekugadzira, track uye yemunda track zvinhu, mijaho, mapaki epasi zvinhu, thermal insulation hwindo mafuremu, nezvimwe.

4. Polyurethane coating:

Polyurethane coating ine yakasimba adhesion, uye iyo yekubikira firimu ine yakanakisa kupfeka kuramba, kudzivirira kwemvura uye makemikari kuramba.Inonyanya kushandiswa kupfekedza fenicha, machira ekuvaka uye mainduki ekudhinda maindasitiri.

5. Polyurethane adhesive:

Kuita kwechigadzirwa chakarapwa kunogona kugadziriswa nekugadzirisa chiyero che isocyanate uye polyol, kuitira kuti igone kuwana kunamatira kwakakwirira kune substrate, yakanakisa kudzivirira kwemvura, kuramba kwemafuta uye kupikisa kemikari.Polyurethane adhesives anonyanya kushandiswa mukurongedza, kuvaka, huni, mota, kugadzira shangu uye mamwe maindasitiri.

6. Biomedical zvinhu:

Polyurethane ine yakanakisa biocompatibility, saka zvishoma nezvishoma inoshandiswa zvakanyanya sebiomedical zvinhu.Inogona kushandiswa mukugadzira ekugadzira emwoyo pacemakers, artificial dialysis membranes, artificial esophagus, artificial dialysis membranes, artificial dialysis membranes.
