I roto i te taiao ahumahi me te arumoni hou, he whānuitia te whakamahinga o ngā Wira i hangaia mai i ngā rauemi rerekē i roto i ngā āhuatanga rerekē nā ō rātou āhuatanga ahurei. Mai i ngā wira nairona, ngā wira nairona whakarewa (MC) ki ngā potae rapa totoka, ngā wira rapa ngohengohe. Kātahi ki ngā wira rapa hangai, ngā wira rapa hangai ārai-tūmau, tae atu ki ngā wira papu me ngā wira rino whakarewa. He ahurei ia o ēnei wira, ā, ka ea i ngā momo taiao whenua uaua me ngā whakaritenga kawe kawenga. Muri iho, ka hipokina hoki e mātou ētahi atu momo wira.
Wira polypropylene, e mōhiotia whānuitia ana ko te wira PP
He rauemi kirihou wera te polypropylene e mōhiotia ana mō tōna ātete ki te pānga, te ātete ki te waikura, te ātete ki te waku, te kore tohu, te kore poke me ngā āhuatanga kore paitini. Kāore he kakara o tēnei rauemi, kāore e waikura, ā, he ātete ki ngā matū waikura maha. Heoi, kāore i roto i a ia ngā matū waikura kaha me ngā matū halogenated. He pai ngā wira polypropylene mō ngā pāmahana mai i te -20°C ki te +60°C. Heoi, ina neke ake te pāmahana taiao i te +30°C, ka whakaitihia tōna kaha kawe.
Wira Polyurethane
Ko te Polyurethane (TPU) he polyurethane thermoplastic. He matua polypropylene, he nairona rānei ō ēnei wira. Ka werohia te polyurethane ki te taha o waho o te matua hei hanga i te mata o te wira. He tino pai ngā āhuatanga o ngā wira polyurethane ki te tiaki i te papa, ki te mimiti i ngā wiri, kāore e tohu, kāore e poke, he ngāwari, he ātete ki te waku, ā, he ātete ki te waikura e te maha o ngā matū kaha. Hei tāpiri. He ātete hoki ki te wai wera me te kohu wai i raro i ētahi āhuatanga. He iti tōna ātete hurihuri. He pai mō te whānuitanga o ngā papa. Ka taea te hanga tae i runga i te tono. Ka tutuki i ngā hiahia rerekē. He pai ngā wira polyurethane thermoplastic monowira mō ngā pāmahana mai i te -45 °C ki te +90 °C. Heoi, ka heke te kaha kawe kawenga i ngā pāmahana taiao i runga ake i te +35 °C.
Wira Elastomer Polyurethane Maka (CPU)
Ko ngā elastomers polyurethane maka (CPU) he elastomers polyurethane thermosetting ka whakahāngaihia mā te tauhohenga matū. Kei roto i ngā rauemi turanga ko ngā polyols polyester, ngā diisocyanates me ngā glycols. Ka whakamahia e tēnei momo wira he matua rino, he konumohe rānei hei matua, ā, ka ringihia te polyurethane ki te taha o waho o te matua. Ka hangaia te mata o te wira mā te whakamaroke i ngā pāmahana teitei. He tino tiaki ngā wira polyurethane kua ringihia i te whenua, he wiri mimiti, he kore tohu, he kore poke, he ātete pai ki te waku, he ngāwari pai, he ātete ki te waikura e te maha o ngā matū kaha, he ātete ki te UV. Hei tāpiri. He tino pai te whakamarie whakahaere, he iti te ātete hurihuri. He iti ake te whakaputa wera ina pāngia e ngā kawenga hihiri. He mā te tae. He pai mō ngā pāmahana mai i te -30°C ki te +70°C. Tae atu ki te +90°C mō ngā wā poto. I ngā pāmahana taiao i raro i te -10°C. Ko tōna pakari te mea pai rawa atu.
He wira polyurethane whakarewa anō (CPU)
Ko ēnei wira polyurethane (CPU) i whakarewahia he mea hanga anō hoki i ngā elastomers polyurethane thermosetting kua whakarewahia mā te tauhohenga matū. He mea hanga ki runga i ngā polyols polyester, diisocyanates me glycols. He āhuatanga tōna o te tiaki i te whenua, te kore tohu, te kore paru, te ātete ki te waku, te ngāwari pai me te ātete ki te waikura o te maha o ngā matū kaha. He ātete hoki ki te UV, he iti rawa te nekehanga pumau. He iti te ātete hurihuri. He iti ake te whakaputa wera ina pāngia e ngā kawenga hihiri, ā, he ātete ki te hydrolysis. He tino pai mō ngā tere teitei ake tae atu ki te 16km/h. Ka taea te whakarite i ngā tae i runga i te tono. Ko te awhe pāmahana e tika ana kei waenga i te -45°C me te +90°C, me te wā poto mōrahi o te +90°C.
Wira Polyurethane Pahuka (PUE)
Ko ngā wira polyurethane pahuka (PUE). E mōhiotia ana ko te polyurethane moroiti. He poraka polymer. He pai te ngāwari o ēnei wira, ā, ko ōna āhuatanga tinana he nui ake i ērā o ētahi atu elastomers moroiti o te kiato kotahi. He pai ngā āhuatanga o ngā wira polyurethane pahuka pērā i te iti o te kiato, te māmā, te ngāwari ki te whakapē, te ngāwari ki te pokepokea, te ātete ki te pānga, te pai o te mimiti oro, te nui o te kawenga, te ngāwari teitei, te pai o te ātete ki te takai, te iti o te pēhanga, te ātete ki te karawarawa, te ātete ki te haehae, te ātete ki te irahiko me te mimiti ru me te ārai. He whānuitia te pakeke. Mai i te takutai moana A10 ki te 100, he pai mō te whakamahi hei rauemi whakarewa.
I te nuinga. He huinga motuhake tō ia o ēnei wira. He āhuatanga motuhake tō ia wira e pā ana ki ngā rauemi, te mahi me te taiao e tika ana. I te wā e whiriwhiri ana i ngā wira, me whakakotahi tēnei i runga i ngā āhuatanga whakamahinga me ngā hiahia motuhake. kia tino whiriwhiria ai te wira tino tika. Nō reira, ka mahi pai.
