Thermoplastic elastomer TPE/TPR matoyi, zvichibva paSEBS neSBS, imhando yemhando yepolymer alloy zvinhu zvine zvakajairika epurasitiki kugadzirisa zvivakwa asi zvimiro zverabha.Ivo zvishoma nezvishoma vakatsiva mapurasitiki echinyakare uye ndizvo zvinosarudzwa zvezvigadzirwa zveChinese kuenda kunze kwenyika uye kutumira kuEurope, America, Australia, Japan nedzimwe nzvimbo.Iyo ine yakanaka tactile elasticity, inochinjika kugadzirisa kwemavara uye kuoma, kuchengetedza kwezvakatipoteredza, halogen-isina, isiri-chepfu uye isina kunaka;Anti kutsvedza uye kupfeka kuramba, kusimba kuneta kuramba, kubatwa zvakanaka kwekuvhunduka, kwakanaka UV kuramba, ozone kuramba uye makemikari kuramba;Panguva yekugadzirisa, haifaniri kuomeswa uye inogona kushandiswa zvakare.Inogona kuve yakaumbwa neyechipiri jekiseni kuumbwa, yakavharwa uye yakasungwa nePP, PE, PS,ABS, PC, PA uye zvimwe matrix zvinhu, kana kuumbwa zvakasiyana.Tsiva yakapfava PVC uye imwe silicone rabha.
Hwema hunoburitswa neTPR matoyi nekuda kwezvikonzero zvakawanda, kusanganisira muchina, nhanho dzekushanda, uye nzira dzekushandisa.Hazvigoneki kuti TPR ichava nekunhuhwirira, asi tinogona kuderedza kunhuhwirira kuitira kuti vanhu varege kunzwa zvakashata, kuitira kuti munhu wose agamuchire.Vagadziri vakasiyana vane maitiro avo, uye kunhuwa kunogadzirwa kwakasiyanawo.Kuti uwane kunhuhwirira kwakajeka, zvinoda musanganiswa wakakwana weformula uye maitiro kuti uve nekuita kwakanaka.
1. Formula
Mazhinji ematoyi anogadzirwa neTPR zvinhu zvine SBS seyakanyanya substrate.SBS inofanirwa kutariswa mukusarudza.SBS pachayo ine kunhuwa uye kunhuhwirira kwemafuta glue kwakakura kupfuura iyo yakaoma glue.Edza kushandisa K glue kuvandudza kuoma, kuderedza huwandu hwePS, uye sarudza mafuta ane high flash point yeparafini wax.Mafuta machena asina kuchena achavawo nekunhuhwirira mushure mekupisa, saka zvinokurudzirwa kusarudza zvigadzirwa kubva kune vanogadzira nguva dzose.
2. Maitiro
TPR zvidhori zvigadzirwa neSBS seyo huru substrate inofanirwa kudzora maitiro.Zviri nani kusashandisa madhiramu ekusanganisa akakwira uye akatwasuka ekusanganisa zvinhu, uye nguva haifanirwe kunge yakareba.Kazhinji kutaura, tembiricha yekugadzira inofanira kudzorwa zvakaderera sezvinobvira.180 ℃ muchikamu chekugera uye 160 ℃ muzvikamu zvinotevera zvakakwana.Kazhinji, SBS iri pamusoro pe200 ℃ inowanzochembera, uye kunhuwa kuchave kwakanyanya.Izvo zvakagadzirirwa TPR zvimedu zvinofanirwa kunyoroveswa nekukurumidza sezvinobvira kuti zviwedzere kunhuhwirira, uye kuve nechokwadi kuti hapana kupisa kwakawanda panguva yekurongedza.
3. Kutevera kugadzirisa
Mushure mekunge matoyi atonhodzwa neTPR jekiseni molding, usaarongedze nekukasira.Tinogona kurega zvigadzirwa zvichivhuvhuta mumhepo kwemazuva maviri.Uye zvakare, essence inogona zvakare kuwedzerwa panguva yejojo yekuumba maitiro kuvhara kuravira kweTPR pachayo.
