He pōʻino anei ka moena kaʻa TPE?

He aha ke ʻano o ka TPE? He pōʻino anei ka moena kaʻa TPE i ke kino o ke kanaka? Me he mea ʻona paha ka mea TPE?

ʻO kēia ka nīnau a nā mea kūʻai aku i kēia manawa. Ma ke ʻano he mea e pili kokoke ana me nā kānaka, ʻo kona pale ʻana i ke kaiapuni a me nā mea ʻawaʻawa ʻole e hoʻopilikia maoli ʻia e ka lehulehu ākea. ʻO ka waiho wale ʻana, ʻo TPE kahi plastik elastomeric me nā waiwai a me nā waiwai PVC.

Ma ke ola o kēlā me kēia lā, ʻo nā lako maʻamau i hana ʻia me nā mea TPE e komo pū ana me nā mea paahana, nā lako luʻu, nā mea haʻuki, nā pahu, nā pā hau, nā mea pāʻani pēpē, nā ukana ukana, nā uea a me nā uwea, nā huahana makua, nā ʻāpana kaʻa, nā mea kākau, nā kiʻiʻoniʻoni palekana kaiapuni, a me ka elastic Plastic. nā huahana e like me nā paipu a me nā sila. Ma hope aʻe, e nānā au i ka wehewehe ʻana i ke ʻano o ka TPE a inā he mea ʻino ia i ke kino:

ʻO ka mea mua, he aha ka TPE?
ʻO TPE, i kapa ʻia ʻo thermoplastic elastomer, he mea me ka elasticity kiʻekiʻe, ka ikaika kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka lāʻau, a me nā ʻano o ka hoʻoheheʻe ʻana. He mea pili i ke kaiapuni, ʻaʻohe mea ʻawaʻawa a palekana, he ākea ākea o ka paʻakikī, he maikaʻi loa ka waihoʻoluʻu, paʻi palupalu, pale ʻana i ka wā, ke kūpaʻa luhi a me ke kūpaʻa wela, ʻoi aku ka maikaʻi o ka hana ʻana, ʻaʻohe pono no ka vulcanization, a hiki ke hana hou ʻia e hōʻemi i nā kumukūʻai. . Hiki ke hoʻoheheʻe ʻia i ʻelua pana. Hiki ke uhi ʻia a hoʻopaʻa ʻia me PP, PE, PC, PS, ABS a me nā mea kumu ʻē aʻe, a i ʻole hiki ke hoʻoheheʻe ʻia.

ʻO ka lua, he mea ʻino anei ka TPE i ke kino?
ʻO TPE kahi mea ʻawaʻawa maikaʻi ʻole, nā mea ʻawaʻawa ʻole i hana ʻole i nā hormone kaiapuni. Eia kekahi, loaʻa iā TPE nā hopena anti-skid a me nā hopena pale. Hoʻoheheʻe ʻia me ka plastic paʻakikī a loaʻa ka hoʻopili maikaʻi me ka mea nui o ka polypropylene. ʻO nā mea ʻelua he palupalu a paʻakikī hoʻi i hui pū ʻia, a me nā kala like ʻelua. Hāʻawi ka PP i ka ikaika o ka ʻokiʻoki, a hāʻawi ʻo TPE i ka waiwai anti-skid o ka papa ʻoki. , ʻOiai e hoʻonui ana i ka nani o ka huahana. Hoʻohālikelike ʻia me nā plastics maʻamau, ʻo ka hoʻolālā TPU me 3-4 mau manawa i ka ikaika ʻaʻole e hoʻoulu i kahi ʻala. Loaʻa i nā mea TPE nā hiʻohiʻona penei:

1.Manaʻo lima kiʻekiʻe: ikaika kiʻekiʻe; kiʻekiʻe resilience; hikiwawe kiʻekiʻe; palupalu a pahee; lehu pipili ʻole.

2.ʻO ka hana kiʻekiʻe: UV kū'ē; kū'ē i ka wā kahiko; ʻakika a me ke kūpaʻa alkali; pale ʻana i ka luhi.

3.Maʻalahi e hana: maikaʻi ka wai; māmā 'umekaumaha; oluolu ke kala. He kūpono no ka hoʻoheheʻe ʻana; hoʻoheheʻe extrusion.

4.Palekana ʻōmaʻomaʻo a me ke kaiapuni: hui me FDA (n-hexane); Nā kūlana hoʻāʻo LFGB (ʻaila ʻoliva).

5.Ke kaʻina hana: hoʻomaʻemaʻe mua i ka mīkini me PP (polypropylene); ʻO ka mahana hoʻoheheʻe he 180-210 ℃.

6.Nā kahua noi: nā huahana pēpē; nā huahana lapaʻau; papaʻaina; nā mea e pono ai i kēlā me kēia lā; nā huahana lumi kuke a me ka lumi lumi; palekana kaiapuni.

7.ʻO nā huahana e koi ana i nā koi ʻano meaʻai.

No laila, ʻaʻohe mea ʻawaʻawa a pili i ka TPE, a hoʻokō i ka palapala hōʻoia ROHS palekana kaiapuni EU. E ʻoluʻolu e hoʻohana.
