I-Snapelastomer 2802 Engasheleli Futhi Engagugi ye-EVA

chaza:

I-Snapelastomer 2802 iyisiguquli se-elastomer esisebenza kahle kakhulu sezinhlelo ze-EVA ne-TPU, esenzelwe ukuthuthukisa ukumelana nokuguguleka kanye nezakhiwo zokubambelela.

Ibamba ngokwethembeka ngaphansi kwezimo ezomile nezimanzi ngenkathi igcina ukuqina, okwenza ifaneleke ezicathulweni zezemidlalo, ezivamile, zemfashini, kanye nezicathulo zesikhumba.

Izinto zihlakazeka kahle kuma-matrices e-EVA kanye ne-TPU, okuqinisekisa ukucutshungulwa okuzinzile kanye nemiphumela ehambisanayo. Isebenzisa indlela ye-viscoelastic, yandisa amazinga okungqubuzana kunokuba iwanciphise, ithuthukisa ngempumelelo ukumelana nokushelela ezindaweni ezimanzi. Emazingeni okulayisha anconyiwe, igcina ubuqotho bomshini wezinto eziyisisekelo. Iyahambisana nezinqubo zokubumba igwebu, i-extrusion, kanye ne-injection.

I-Snapelastomer 2802 Elastomer Engasheleli Futhi Engagugi

I-Snapelastomer 2802 iyisiguquli se-elastomer esisebenza kahle kakhulu esenzelwe izinhlelo ze-EVA ne-TPU, esihlinzeka ngokumelana nokuguguleka okuthuthukisiwe kanye nokusebenza okuthembekile kokubambelela.
Ngokusebenzisa indlela ye-viscoelastic, kwandisa ngempumelelo ukungqubuzana ngaphansi kwezimo ezomile nezimanzi, okusiza ekuvimbeleni ukushelela, ikakhulukazi ezindaweni ezivezwe umswakama.
Le nto inikeza ukuhlakazeka okuhle kakhulu kanye nokuziphatha okuzinzile kokucubungula, okwenza kube lula ukuhlanganiswa nezinqubo zokubumba ngegwebu, ukukhipha, kanye nokufaka umjovo. Ihlinzeka ngokuthuthukiswa kokusebenza ngenkathi igcina izakhiwo zemishini zento eyisisekelo, iqinisekisa inhlanganisela elinganiselayo yokuqina nokusebenza. Ilungele ukusetshenziswa kwezicathulo okuhlanganisa ezemidlalo, izicathulo ezivamile, izicathulo zemfashini, kanye nezicathulo zesikhumba lapho kudingeka khona ukuphepha, ukubamba, kanye nokuphila isikhathi eside.

Izinzuzo Eziyinhloko

1) Thuthukisa ukumelana nokuguguleka kanye nezakhiwo zokungasheleli ze-EVA;

2) Ukwephuka kwevolumu ye-DIN yomkhiqizo kungancishiswa kakhulu, futhi ukumelana nokuguguleka kuthuthukiswa kakhulu, okwandisa ngempumelelo impilo yenkonzo yesisekelo sezicathulo;

3) Ngokungafani nezengezo zokumelana nokuguguleka zendabuko ezinciphisa i-friction coefficient, lo mkhiqizo, ngokusebenzisa indlela ye-viscoelastic, ungandisa i-friction coefficient eyomile/emanzi yento, ukuxazulula inkinga "yokushelela lapho amanzi ekhona" ku-EVA sole;

4) Ngemva kokwelashwa kokuhambisana kwe-interface, i-Snapelastomer2802 inokusabalalisa okuhle ohlelweni lwe-foam lwe-EVA;

5) Ngesilinganiso esinconywayo, ayinawo umthelela omkhulu emandleni okudonseka, amandla okudabuka kanye nokuqina kwezinto eziyisisekelo, futhi ingafinyelela ukuguqulwa kokusebenza ngaphandle kokulahla izakhiwo eziyisisekelo……

Isicelo

Kunconywa amazinga okwengeza aphakathi kuka-5.0 ~ 10.0%. Kunconywa kakhulu ukuthi kuhlanganiswe ama-Snapelastomer2802 nama-thermoplastic pellets ngaphambi kokufakwa enkambisweni yokukhipha.

Iphakheji

25Kg ngesikhwama, isikhwama sephepha esenziwe ngezandla esinesikhwama se-PE sangaphakathi.
