ʻO ka ʻokoʻa ma waena o ka tpr a me ka BR rubber i ka ʻoihana caster he mea puni, no ka poʻe i launa ʻole me ka pūnaewele he mea paʻakikī loa ke hoʻokaʻawale, i kēia lā mai ke kumumanaʻo i hui pū ʻia me ka hihia, no nā hoaaloha e wāwahi i ka ʻokoʻa ma waena o ka tpr a me ka BR rubber i ka hohonu.
ʻO tpr ka pōkole o Thermo-Plastic-Rubber material, hiki iā mākou ke kapa iā ia he thermoplastic rubber material. He mea palupalu thermoplastic rubber me ka elasticity me ka ʻole o ka vulcanization, a hiki ke hana pololei ʻia a hoʻoheheʻe ʻia (e like me ka injection molding, extrusion, blow molding, etc.).
1, ka hoʻohana ʻana i ka pae mahana -45-90 ℃, ʻo ka mea maʻamau i ʻōlelo ʻia ʻo tpr e pili ana i ka substrate SBS, ʻo kona mau waiwai kemika penei: ke kūpaʻa ʻana o ke kinikini, ke kūpaʻa ʻana o ka ʻelemakule ma ke ʻano laulā, ke kūpaʻa ʻana o ka mahana 70-75 ℃. Inā makemake ʻoe i nā mea kūpaʻa ʻana o ka ʻelemakule maikaʻi, hiki iā ʻoe ke koho i nā mea kumu SEBS i hoʻololi ʻia.
2, ʻoi aku ka maikaʻi o ke kūpaʻa o ka laholio BR a me ke kūpaʻa abrasion, anti-slip a me ka hana omo haʻalulu, palupalu a ʻoluʻolu hoʻi ka mea tpr ma mua o ka laholio, akā ʻaʻole maikaʻi ka ikaika tensile o ka mea, ke kūpaʻa i ka luhi a me nā waiwai mechanical e like me ka laholio vulcanized.
3, nā ʻano o ke kaiapuni, ʻo ka mea tpr he palupalu palupalu aloha i ke kaiapuni, ʻo nā mea weliweli nui e like me ka plasticizers phthalates Phthalate, nonylphenol NP, PAHs PAHs ʻike ʻia, e like me ROHS, REACH, EN71-3, ASTMF963 mau kūlana hoʻāʻo palekana kaiapuni.
4, nā ʻano paʻakikī, hiki ke hoʻololi ʻia ka paʻakikī o ka mea tpr ma ke kahakai o 5-100 degere o kona paʻakikī, hiki ke hoʻololi ʻia nā mea i hoʻololi ʻia e SEBS i ka paʻakikī haʻahaʻa.
He mea polymer elastic loa ka BR rubber me ka deformation reversible, elastic i ka mahana o ka lumi, hiki ke hana i ka deformation nui ma lalo o ka hana o kahi ikaika waho liʻiliʻi, a hiki ke hoʻihoʻi i ke kūlana mua ma hope o ka wehe ʻana i ka ikaika waho. No ka polymer amorphous piha ka rubber, haʻahaʻa kona mahana hoʻololi aniani (T g), ʻoi aku ka nui o ke kaumaha molekala, ʻoi aku ma mua o nā haneli haneli.
E nānā i ka ʻokoʻa ma waena o nā mea hoʻoheheʻe TPR a me nā mea hoʻoheheʻe laholio:
Nui nā mea hana no ka ʻili o nā huila o nā mea hoʻoheheʻe, e like me nā mea hoʻoheheʻe TPU, nā mea hoʻoheheʻe PP, nā mea hoʻoheheʻe TPR, nā mea hoʻoheheʻe PU, nā mea hoʻoheheʻe TPE, nā mea hoʻoheheʻe nylon, nā mea hoʻoheheʻe laholio a pēlā aku.
1, ʻoi aku ka palupalu a me ka mālie o nā mīkini wiliwili BR ma mua o nā mīkini wiliwili TPR.
2, hoʻohālikelike ʻia me ke kumukūʻai, ʻaʻole hiki ke hana hou ʻia ka laholio, hiki ke hana hou ʻia ka TPR, ʻoi aku ka liʻiliʻi o ke kumukūʻai o nā mīkini hoʻoheheʻe TPR ma mua o nā mīkini hoʻoheheʻe laholio BR.
4, mai ka manaʻo o ka palekana kaiapuni, he mea aloha kaiapuni hou ʻo TPR, ʻaʻole aloha kaiapuni ka laholio BR.
