Kuti uderedze mutengo wechigadzirwa uye uwane mamwe maitiro,polyurethane thermoplasticelastomers inogona kushandiswa seanowanzo shandiswa toughening ejenti kuomesa akasiyana thermoplastic uye yakagadziridzwa rubha zvinhu.
Nekuda kwepolyurethaneKuve polar yakawanda, inogona kuenderana ne polar resin kana rubber, sepaya inoshandiswa pamwe chete ne chlorinated polyethylene (CPE) kugadzira zvigadzirwa zvekurapa;Kusanganiswa neABS kunogona kutsiva kushandiswa kweinjiniya thermoplastic mapurasitiki;Kana ichishandiswa pamwe chete nepolycarbonate (PC), ine zvimiro zvakaita semafuta kuramba, mafuta anopokana, uye kukanganisa kupikisa, uye inogona kushandiswa kugadzira mitumbi yemotokari;Kusanganiswa nepolyester kunogona kuvandudza kushanda kwayo kwekuoma;Mukuwedzera, inogona kunyatsoenderana ne polyvinyl chloride, polyoxymethylene (POM), kana polyvinylidene chloride;Polyester polyurethane inogona kunyatsoenderana ne15% nitrile rabha kana 40% nitrile rabha / polyvinyl chloride musanganiswa rabha;Polyether polyurethane inogonawo kunyatsoenderana ne40% nitrile rubber/polyvinyl chloride musanganiswa wekunamira;Inogonawo kuwirirana ne acrylonitrile styrene (SAN) copolymers;Inogona kuumba inopindirana network (IPN) chimiro chine reactive polysiloxanes.Ruzhinji rwezvataurwa pamusoro apa zvakasanganiswa zvinonamira zvakatogadzirwa zviri pamutemo.
Mumakore achangopfuura, kwave nekuwedzera kuwanda kwekutsvagisa pamusoro pekuomeswa kwePOM neTPUmuChina.Iko kusanganiswa kweTPU nePOM hakungonatsiridza kukwirisa-tembiricha kuramba uye michina zvimiro zveTPU, asiwo zvakanyanya kuomesa POM.Vamwe vaongorori vakaratidza kuti mukuyedza kutyoka, zvichienzaniswa nePOM matrix, maPOM alloys ane TPU yekuwedzera anochinja kubva pakuputsika kuenda kune ductile fracture.Kuwedzerwa kweTPU kunopawo POM ine chimiro chendangariro kuita.Iyo crystalline dunhu rePOM inoshanda seyakagadziriswa chikamu chechimiro memory alloy, nepo amorphous dunhu reamorphous TPU nePOM inoshanda sechikamu chinodzoreredza.Kana tembiricha yekupindura yekudzoreredza iri 165 ℃ uye nguva yekudzoreredza iri 120 s, mwero wekudzoreredza weiyo alloy unosvika pamusoro pe95%, uye mhedzisiro yekudzoreredza ndiyo yakanyanya kunaka.
TPU yakaoma kuti ienderane neasiri-polar polymer zvinhu zvakaita se polyethylene, polypropylene, ethylene propylene rabha, butadiene rabha, isoprene rabha, kana tsvina yehupfu yerabha, uye haigone kuburitsa zvinhu zvakaumbwa zvine kuita kwakanaka.Naizvozvo, nzira dzekurapa dzepamusoro dzakadai seplasma, corona discharge, wet chemistry, primer, flame, kana reactive magasi anowanzo shandiswa kune yekupedzisira.Semuyenzaniso, zvigadzirwa zvemumhepo zveAmerica uye makambani emakemikari anogona kuvandudza zvakanyanya kubhenda modulus, kusimba kwesimba, uye kupfeka kupikisa kwe-ultra-high molecular weight polyethylene poda yakatsetseka ine huremu hwema 3-5 miriyoni mushure meF2/O2 inoshanda gasi pamusoro pekurapa, uye kuwedzera kune polyurethane elastomers muchiyero che10%.Uyezve, F2/O2 inoshanda gasi pamusoro pekurapa inogona kuiswa kune yakanamirwa yakareba mapfupi fiber ane hurefu hwe6-35mm yataurwa pamusoro, iyo inogona kuvandudza kuomarara uye kubvarura kuomarara kwechinhu chinoumbwa.
