Ihe dị iche n'etiti ihe nkedo rọba BR na ihe nkedo TPR

Ihe dị iche n'etiti tpr na BR roba n'ime ụlọ ọrụ caster bụ ihe niile, maka ndị na-anaghị akpakọrịta na netwọk ahụ, ọ na-esiri ike ịmata ọdịiche dị n'etiti tpr na BR roba n'ụzọ miri emi.

tpr bụ mkpọbiri nke ihe Thermo-Plastic-Rubber, anyị nwere ike ịkpọ ya ihe roba thermoplastic. Ọ bụ ihe roba dị nro nke thermoplastic nwere ike ịgbatị ya na-enweghị vulcanization, a pụkwara ịhazi ya ozugbo ma kpụzie ya (dịka ịkpụzi ntụtụ, extrusion, ịkpụzi ihe ọkụ, wdg).

1, ojiji nke oke okpomọkụ -45-90 ℃, a na-ekwukarị na ihe tpr dabere na SBS substrate, ihe ndị dị na kemịkalụ ya bụ ndị a: iguzogide mabụl, iguzogide ịka nká n'ozuzu, iguzogide okpomọkụ 70-75 ℃. Ọ bụrụ na ịchọrọ ezigbo ihe mgbochi okpomọkụ iguzogide ịka nká, ị nwere ike ịhọrọ ihe ndị e ji ihe SEBS gbanwee.

2, BR BR resistance na ezigbo mgbochi abrasion, mgbochi mmịpụta na arụmọrụ nnabata ujo dị mma, tpr ihe dị nro ma dị mma karịa roba, mana ike nrụgide ihe ahụ, ike ọgwụgwụ na ihe onwunwe igwe adịghị mma dị ka roba vulcanized.

3, njirimara gburugburu ebe obibi, ihe tpr dị ka roba dị nro nke na-anaghị emebi gburugburu ebe obibi, ihe ndị bụ isi dị ize ndụ dị ka plastikizers phthalates Phthalate, nonylphenol NP, nchọpụta PAHs PAHs, dịka ROHS, REACH, EN71-3, ASTMF963 si dị.

4, njirimara siri ike, enwere ike ịgbanwe ihe tpr na ike Shore site na ogo 5-100 nke ike ya, enwere ike ịgbanwe ihe ndị dabere na SEBS ka ọ bụrụ obere ike.

Rọba BR bụ ihe polymer na-agbanwe agbanwe nke ukwuu nke nwere mgbanwe a na-agbanwe agbanwe, na-agbanwe agbanwe na okpomọkụ ụlọ, nwere ike imepụta nnukwu mgbanwe n'okpuru ọrụ nke obere ike mpụga, ma nwee ike iweghachi ọnọdụ mbụ mgbe ewepụsịrị ike mpụga. Rọba bụ nke polymer amorphous kpamkpam, okpomọkụ mgbanwe iko ya (T g) dị ala, ibu molekul na-abụkarị nnukwu, karịa ọtụtụ narị puku.

Lee ihe dị iche n'etiti ihe nkedo TPR na ihe nkedo rọba:

E nwere ọtụtụ ihe eji arụ ọrụ maka elu wiil nke ihe mkpuchi, dịka ihe mkpuchi TPU, ihe mkpuchi PP, ihe mkpuchi TPR, ihe mkpuchi PU, ihe mkpuchi TPE, ihe mkpuchi naịlọn, ihe mkpuchi rọba na ihe ndị ọzọ.

1, ihe nkedo rọba BR dị nro ma dị jụụ karịa ihe nkedo TPR.

2, ma e jiri ya tụnyere ọnụ ahịa ya, a pụghị imegharị rọba ọzọ, a pụrụ imegharị TPR ọzọ, TPR na-efu obere ego karịa BR.

4, site n'echiche nke nchekwa gburugburu ebe obibi, TPR bụ ihe ọhụrụ na-adịghị emebi gburugburu ebe obibi, roba BR adịghị emebi gburugburu ebe obibi.
