Kuti tideredze mitengo yezvigadzirwa uye kuti tiwane mamwe mabasa,polyurethane thermoplasticMa elastomer anogona kushandiswa sezvinhu zvinosimbisa zvinhu zvakasiyana-siyana zve thermoplastic uye rabha zvakagadziriswa.
Nekuda kwepolyurethaneSezvo iri polar polymer ine polar yakawanda, inogona kuenderana nema polar resins kana rabha, senge painoshandiswa pamwe chete ne chlorinated polyethylene (CPE) kugadzira zvigadzirwa zvekurapa; Kusanganisa neABS kunogona kutsiva kushandiswa kwemapurasitiki e thermoplastic einjiniya; Kana ikashandiswa pamwe chete ne polycarbonate (PC), ine zvinhu zvakaita sekudzivirira mafuta, kudzivirira mafuta, uye kudzivirira kukanganiswa, uye inogona kushandiswa kugadzira miviri yemotokari; Kusanganisa ne polyester kunogona kuvandudza mashandiro ayo ekusimba; Pamusoro pezvo, inogona kuenderana zvakanaka ne polyvinyl chloride, polyoxymethylene (POM), kana polyvinyllidene chloride; Polyester polyurethane inogona kuenderana zvakanaka ne 15% nitrile rabha kana 40% nitrile rubber/polyvinyl chloride blend rabha; Polyether polyurethane inogonawo kuenderana zvakanaka ne 40% nitrile rubber/polyvinyl chloride blend adhesive; Inogona zvakare kuenderana pamwe chete ne acrylonitrile styrene (SAN) copolymers; Inogona kuumba interpenetrating network (IPN) structure ine reactive polysiloxanes. Ruzhinji rwemaginamisi akasanganiswa ataurwa pamusoro apa akatogadzirwa zviri pamutemo.
Mumakore achangopfuura, kwave nekuwedzera kwekutsvaga pamusoro pekusimba kwePOM neTPUmuChina. Kusanganiswa kweTPU nePOM hakungogadzirisi chete kuramba kupisa kwakanyanya uye hunhu hwemakanika hweTPU, asiwo kunosimbisa POM zvakanyanya. Vamwe vaongorori vakaratidza kuti mukuyedzwa kwekupwanyika kwetensile, zvichienzaniswa nePOM matrix, maPOM alloys ane TPU addition anochinja kubva pakupwanyika kwebrittle kuenda pakupwanyika kweductile. Kuwedzerwa kweTPU kunoitawo kuti POM ive nechimiro chekurangarira. Nzvimbo yecrystalline yePOM inoshanda sechikamu chakagadziriswa chechimiro chekurangarira, nepo nzvimbo isina chimiro yeTPU nePOM isina chimiro inoshanda sechikamu chinodzoserwa. Kana tembiricha yekupindura yekudzosa iri 165 ℃ uye nguva yekudzosa iri 120 s, chiyero chekudzosa chealloy chinosvika pamusoro pe95%, uye mhedzisiro yekudzosa ndiyo yakanakisa.
TPU yakaoma kuenderana nezvinhu zvisiri zvepolar polymer zvakaita se polyethylene, polypropylene, ethylene propylene rabha, butadiene rabha, isoprene rabha, kana waste rabber powder, uye haigone kugadzira zvinhu zvakasanganiswa zvine mashandiro akanaka. Nokudaro, nzira dzekurapa pamusoro dzakadai seplasma, corona discharge, wet chemistry, primer, flame, kana reactive gases dzinowanzo shandiswa kune yekupedzisira. Semuenzaniso, zvigadzirwa zvemhepo zvekuAmerica nemakambani emakemikari zvinogona kuvandudza zvakanyanya kukotama kwemodulus, simba rekudhonza, uye kuramba kupfeka kwe ultra-high molecular weight polyethylene fine powder ine huremu hwemamorekuru hwemamiriyoni 3-5 mushure meF2/O2 active gas surface treatment, uye kuiwedzera kune polyurethane elastomers mu10%. Uyezve, F2/O2 active gas surface treatment inogona kushandiswa kune fibers pfupi dzakareba dzine hurefu hwe6-35mm dzataurwa pamusoro apa, izvo zvinogona kuvandudza kuomarara uye kuomarara kwechinhu chakasanganiswa.
