He rauemi maha ngā whakamahinga o te Thermoplastic Polyurethane (TPU) e mōhiotia ana mō tōna pakari me tōna ātete. Heoi, i ētahi whakamahinga, me whakaiti pea te pakeke o ngā kirikiri TPU me te whakapakari anō i te ātete ki te pakū.
Ngā rautaki hei whakaiti i te mārō o te TPU me te whakapai ake i te taurite ātete ki te pakū.
1. Te whakaranu ki ngā rauemi ngawari ake
Ko tētahi o ngā huarahi māmā rawa atu ki te whakaiti i te pakeketanga o te TPU ko te whakaranu ki tētahi rauemi kirihou ngohengohe. Ko ngā kōwhiringa noa ko te TPE (Thermoplastic Elastomers) me ngā momo TPU ngohengohe.
Mā te whiriwhiri āta i te rauemi ngohengohe me te ōwehenga o tōna whakaranu ki te TPU ka āwhina i te whakatutuki i te taumata whakaiti pakeke e hiahiatia ana.
2. He Huarahi Hou: Te Whakaranu i ngā Matūriki TPU me ngā Rauemi Ngāwari Hou a Si-TPV
Mā te whakaranu i ngā kirikiri TPU 85A me te rauemi ngohengohe SILIKE Si-TPV (dynamic vulcanizate thermoplastic silicone-based elastomer), ka tutuki i tēnei tikanga te taurite e hiahiatia ana i waenga i te whakaiti i te pakeketanga me te ātete ki te karawarawa, me te kore e whakararu i ōna āhuatanga e hiahiatia ana.
Te huarahi hei whakaiti i te mārō o ngā matūriki TPU, te Tātai me te Aromatawai:
Mā te tāpiri o te 20% Si-TPV ki te Mārō o te 85A TPU ka whakaitihia te mārō ki te 79.2A.
Tuhipoka:Ko ngā raraunga whakamātautau o runga ake nei ko ā mātou raraunga whakamātautau taiwhanga, ā, kāore e taea te mārama he herenga tēnei hua, me whakamātautau te kiritaki i runga i tā rātou ake tikanga.
Heoi, he mea noa te whakamātautau me ngā ōwehenga ranunga rerekē, ko te whāinga kia tutuki ai te huinga tino pai o te ngawari me te ātete ki te pakū.
3. Te Whakauru i ngā Whakakī Ātete-Pakarukaru
Hei whakarei ake i te ātete ki te pakū, e kī ana ngā tohunga kia whakauruhia he whakakī motuhake pērā i te pango waro, ngā muka karāhe, te silicone masterbatch, te silicon dioxide rānei. Ka taea e ēnei whakakī te whakapakari i ngā āhuatanga ātete kakahu o te TPU.
Heoi anō, me whai whakaaro nui ki te rahinga me te horapa o ēnei whakakī, nā te mea ki te nui rawa ka pā ki te ngāwari o te rauemi.
4. Ngā Kaiwhakaahua me ngā Ākena Whakangawari
Hei tikanga whakaiti i te pakeketanga o te TPU, ka whakamahia pea e ngā Kaihanga TPU ngā mea whakapūmau kirihou, ngā mea whakangawari rānei. He mea nui kia whiriwhiria he mea whakapūmau kirihou e tika ana hei whakaiti i te pakeketanga me te kore e whakararu i te ātete ki te pakū. Ko ngā mea whakapūmau kirihou e whakamahia ana me te TPU ko te dioctyl phthalate (DOP) me te dioctyl adipate (DOA). Me āta whakarite kia hototahi te mea whakapūmau kirihou kua whiriwhiria ki te TPU, ā, kāore e pā kino ki ētahi atu āhuatanga pēnei i te kaha kume, te ātete matū rānei. Hei tāpiri, me tino whakahaere te horopeta o ngā mea whakapūmau kirihou kia mau tonu ai te taurite e hiahiatia ana.
5. Te Whakatikatika i ngā Tawhā Whakaputa me te Tukatuka
He mea nui te whakarerekē i ngā tawhā o te whakaputa me te tukatuka hei whakatutuki i te huinga e hiahiatia ana o te whakaiti i te pakeke me te whakanui ake i te ātete ki te pakū. Ko te tikanga o tēnei ko te whakarerekē i ngā tawhā pēnei i te pāmahana, te pēhanga, me ngā tere whakamatao i te wā o te whakaputa.
Mā te iti o ngā pāmahana whakaputa me te āta whakamatao ka hua ake he TPU ngohengohe ake, me te arotau anō hoki i te marara o ngā whakakī ātete-kura.
6. Ngā Tikanga Tukatuka-Mua
Mā ngā tikanga tukatuka-muri pērā i te whakamahana, te totoro, tae noa ki ngā maimoatanga mata ka taea te whakapakari ake i te ātete ki te pakū me te kore e whakararu i te pakeketanga.
Mā te whakamahana, ina koa, ka taea te whakapai ake i te hanganga tioata o te TPU, kia ātete ake ai ki te kakahu me te haehae.
Hei whakamutunga, he maha ngā āhuatanga o te tukanga e tutuki ai te taurite o te whakaiti i te pakeke o te TPU me te whakapai ake i te ātete ki te pakū. Ka taea e ngā Kaihanga TPU te whakamahi i te kōwhiringa rauemi, te whakaranu, ngā whakakī ātete-pakū, ngā mea whakakoi kirihou, ngā Ākena Whakangawari, me te whakahaere tika i ngā tawhā whakaputa hei whakatikatika i ngā āhuatanga o te rauemi kia rite ki ngā whakaritenga ahurei o tētahi tono.
Koinei tāu e hiahia ana He Tikanga Toa e whakaiti ana i te Mārō o te Matūriki TPU me te Whakapai ake i te Ātete ki te Waro!
