E hia ōu mōhiotanga mō ngā taura polyurethane? (Tara TPU)
Taura PolyurethaneKo te kupu "s" e pā ana ki ngā taura e whakamahi ana i ngā rauemi polyurethane hei whakamarumaru, hei hipoki rānei. Ko tō rātou ātete kakahu nui e pā ana ki te ātete kakahu nui o te hipoki taura me te paparanga whakamarumaru.
Ko te rauemi polyurethane e whakamahia ana i roto i ngā taura e kiia whānuitia ana ko te TPU, he rapa polyurethane elastomer thermoplastic. E wehea ana ki te momo polyester me te momo polyether, me te whānuitanga pakeke (60HA-85HD), te ātete kakahu, te ātete hinu, te mārama me te pīataata. Ehara i te mea he tino pai ngā āhuatanga o te TPU, he ātete kakahu teitei, he kaha teitei, he kaha me te ātete koroheketanga, engari he rauemi pakari hoki e pai ana ki te taiao.
I tēnei rā, ka ārahi a Lansheng Cable i a koe mā roto i ngā āhuatanga matua e 8 me ngā wāhanga whakamahinga o te taura polyurethane.
8 ngā āhuatanga matua：
1. Ātete mau
Ina pāngia te taura e ngā mahi ā-mīhini pēnei i te waku, te rakuraku me te huri i te wā e whakamahia ana, ka āta pakaru haere tōna mata, nō reira he mea tino nui te kaha o te whiriwhiri rauemi ki te pakaru.
He tino pai te ātete o ngā rauemi mata kirihou TPU ki te kakahu, ā, e rima ngā wā e ātete ana ki te kakahu i ngā taura kua whakakikoruatia ki te rapa maori. Ko tētahi o ngā rauemi whiriwhiri tuatahi mō ngā hua ātete ki te kakahu.
2. Mahi kume
Ko te kaha kume o ngā taura polyurethane e tae atu ana ki te 38MPa, ā, ko te kaha kume o ngā taura ringaringa rapa noa (tētahi o ngā taura tino noa i te mākete) he 8-12MPa anake.
Ina whakamahia te taura i roto i te taiao e kaha ana te kume, he iti te pānga o te anga rapa o te anga taura, ā, ka ngawari te pakaru o te matua i muri i te taumahatanga o waho. Ko te ātete kume pai o te anga taura polyurethane me te whakamarumaru he mahi tiaki pai ki te matua waea, kia roa ai, kia pakari ai.
3. Mahi haehae
Ko te kaha haehae te kaha o te rauemi ki te ātete i te haehae. I te nuinga o te wā, he nui te ātete haehae o te TPU, ā, he tino pai te kaha haehae ki te whakataurite ki ētahi rapa me te kirihou e whakamahia whānuitia ana.
4. Mahi hurihuri
He maha ngā taura kirihou (pērā i te RVV) ka pakaru noa i raro i ngā taumahatanga auau. Ka taea e ngā taura polyurethane te pupuri i te ātete piko pai rawa atu i raro i ngā taiao rerekē, ā, koinei tētahi o ngā kōwhiringa pai rawa atu mō ngā taiao piko auau.
5. Ātete ki te waikura
He pai te ātete wai o ngā taura polyurethane i raro i te pōuriuri, ā, e kore e kitea te waikura i roto i te 1 ki te 2 tau, inā koa he pai ake te raupapa polyether.
6. Te ātete pāmahana teitei me te ātete waikura
I te nuinga o te wā, ka ngawari te waikura o ngā rauemi mata kirihou i roto i te taiao neke atu i te 70℃ mō te wā roa, ā, he pai te kaha o te TPU ki te ārai i te mate; i te nuinga o te wā, ka taea e te ātete pāmahana TPU te eke ki te 120℃.
7. Ātete hinu me ngā āhuatanga ātete rongoā
He rauemi pūmua tino pōro te TPU, he iti noa te hononga ki ngā hinu kohuke kore-pōro, ā, tata kore e waikura i roto i ngā hinu wahie (pērā i te hinu kerosene, te penehīni) me ngā hinu miihini (pērā i te hinu waipēhi, te hinu miihini, te hinu whakahinuhinu, me ētahi atu); i roto i ēnei, he pai ake ngā hua raupapa polyester i roto i ngā taura polyurethane.
8. Mahi pāmahana iti
He tino pai te ātete o ngā taura polyurethane ki te pāmahana iti, ā, ka eke ki te -50℃. Ka taea e rātou te whakakapi i ngā momo mara e kore e taea te whakamahi i ngā taura PVC me te ringaringa rapa nā te pakarukaru o te pāmahana iti. He tino pai mō ngā taura e whakamahia ana i ngā wāhi tino makariri.
Ngā wāhi tono：
01Taura tono moana
E whā ngā momo taura ruku wai e taea te wehewehe.
Mai i te tirohanga hanganga, ka wehea te nuinga ki ngā taura raro moana matua-toru me ngā taura raro moana matua-kotahi. Ka whakamahia e ngā raina ngaohiko-waenga me ngā taura raro moana matua-toru, ā, ka whakamahia e ngā raina ngaohiko-tiketike ngā taura raro moana matua-kotahi; mai i te tirohanga mahi, i te haurua rautau ki muri, he mahi tuku hiko māmā noa iho ngā taura raro moana. Ināianei ka whakauruhia e ngā taura raro moana ngā mahi e rua, ka whakatinanahia te tuku hiko me ngā tohu i runga i te raina taura kotahi; mai i te tirohanga hanganga whakamahana, ka wehea ki ngā taura raro moana whakakīia ki te hinu me ngā taura raro moana kirihou whakakīia; mai i te tirohanga momo kawenga, ka wehea ki ngā taura raro moana DC me ngā taura raro moana AC. Ko ngā āhuatanga o ngā taura raro moana DC he iti ngā mate me te ngāwari ki te whakatutuki i te tuku tawhiti, engari kāore i te nui te wheako tono o ngā taura raro moana DC. He nui ngā utu hanga tautoko o ngā teihana whakawhiti DC, ā, he nui ngā taura raro moana AC, engari kua pakari te hangarau whakahaere me te tiaki, ā, he iti ngā utu hanga tautoko. Nō reira, me mahi e ngā kaihoahoa raina taura raro moana ngā whakawhitiwhitinga hangarau me te ōhanga kia nui ake ai ngā painga.
02 Ngā karetao ahumahi me ngā Taura Roboticngā
E mārama ana kua neke atu i te haurua o ngā karetao ahumahi hou o te ao kua tāutahia ki Haina, ā, he nui hoki te ōwehenga o ngā karetao i hangaia ki Haina. Hei wāhanga e rite ana ki ngā karetao, kāore e taea te whakaiti i te hiahia mō te whanaketanga taura karetao. Kei te puāwai te umanga karetao ahumahi i Haina, ā, kei te kukume mai hoki i te hiahia o ngā kamupene taura. Hei wāhanga nui o ngā karetao, Waea me te Taura kua whakaatu i te tipu tere o te tono mākete, ā, ka whakatūwherahia e ngā kamupene waea me te taura he whai wāhitanga onge mō te whanaketanga me te panonitanga.
03 Mīhini tauranga me te taura rīra kerēne gantry
Me āhei te taura rīra kerēne gantry ki te takai aunoa i te taura, ā, kaua te taipana taraiwa o te rīra taura e iti iho i te taipana takai mōrahi e hiahiatia ana i te wā e takai ana i te taura. I te wā e tukuna ana te taura, me iti rawa te kaha kukume e pā ana ki te ara iahiko taura. Mō ngā taura kāore he matua whakakaha, ko te kaha kume mōrahi e whakaaetia ana e pā ana ki te wāhanga whakawhiti o te ara iahiko parahi ko 20N/mm². Mō te tere takai taura e hiahiatia ana, mō te taumaha rānei o te taura, me tāpiri he taura waea maitai whakakaha e taea te tu atu i te kaha kukume e hiahiatia ana hei matua.
04Ngā taura mīhini hangarau keri
Ko ngā waea me ngā taura o ngā mīhini keri maina e hiahia ana kia pai ake te ātete ki te kakahu, te ātete ki te waikura, te ātete ki te pāmahana teitei me te ātete ki te waikura, nō reira he tino pakari hoki ngā whakaritenga mō ngā rauemi waea me te taura.
