Shandisa nzira 7 idzi kuona TPE neTPU!

TPE iri kutaura zvakanyanya izwi rakajairika kune ese thermoplastic elastomers.Inorongwa sezvinotevera:

Asi izvo zvinowanzonzi TPE isanganiswa yeSEBS / SBS + PP + naphthenic mafuta + calcium carbonate + axiliaries.Iyo inonzi zvakare inoshamwaridzana nemamiriro ekunze epurasitiki yakapfava muindasitiri, asi dzimwe nguva inonzi TPR (inonyanya kunzi muZhejiang neTaiwan)).TPU, inonziwo polyurethane, ine mhando mbiri: polyester mhando uye polyether mhando.

TPE neTPU zvese zviri zviviri thermoplastic zvinhu zvine rubber elasticity.TPE neTPU zvinhu zvine kuoma kwakafanana dzimwe nguva zvinogona kunetsa kusiyanisa pakati peTPE neTPU nekungozviona neziso rakashama.Asi kutanga neruzivo, isu tinogona kuongorora mutsauko uye mutsauko pakati peTPE neTPU kubva kune akawanda maficha.

1.Transparency

Kujeka kweTPU kuri nani pane kweTPE, uye hazvisi nyore kunamatira seyakajeka TPE.

2. Chikamu

Chikamu cheTPE chinosiyana zvakanyanya, kubva pa0.89 kusvika 1.3, nepo TPU inotangira pa1.0 kusvika 1.4.Muchokwadi, panguva yekushandiswa kwavo, ivo vanonyanya kuoneka muchimiro chemisanganiswa, saka iyo chaiyo giravhiti inochinja zvakanyanya!

3.Kuramba kwemafuta

TPU ine yakanaka mafuta kuramba, asi zvakaoma kuti TPE isarambe mafuta.

4.After kusvirwa

TPE ine kunhuhwirira kwakareruka kana uchipisa, uye hutsi hunopisa hudiki uye hwakareruka.TPU combustion ine imwe kunhuhwirira kwakapinza, uye kune kamutsindo kanoputika kana uchipisa.

5.Mechanical properties

TPU's elasticity uye elastic recovery properties (flexion resistance uye creep resistance) zviri nani pane TPE.

Chikonzero chikuru ndechekuti chimiro cheTPU ndeye polymer homogeneous chimiro uye ndeyechikamu chepolymer resin.TPE chinhu che alloy chine multi-phase chimiro chakasanganiswa ne-multi-component musanganiswa.

Yakakwirira-yakaoma TPE kugadzirisa inotarirwa kune chigadzirwa deformation, nepo TPU ichiratidza yakanakisa elasticity mune ese kuomarara renji, uye chigadzirwa hachisi nyore kukanganisa.

6.Temperature resistance

TPE iri -60 madhigirii Celsius ~ 105 madhigirii celsius, TPU iri -60 madhigirii celsius ~ 80 madhigirii celsius.

7.Kuonekwa uye kunzwa

Kune zvimwe zvigadzirwa zvakawandisa, zvigadzirwa zvakagadzirwa neTPU zvine hutsinye hwekunzwa uye yakasimba friction kuramba;nepo zvigadzirwa zvakagadzirwa neTPE zvine kutetepa uye kupfava kunzwa uye kushomeka kwekuita.

Kupfupisa, zvese TPE neTPU zvinhu zvakapfava uye zvine kunaka kwerabha elasticity.Mukuenzanisa, TPE yakanyanya kunaka maererano netactile kunyaradza, nepo TPU ichiratidza yakanakisa elasticity uye simba.
