He pai te matotoru o te piripiri TPU e hangai ana ki te whakarewa
mō te TPU
Mā te TPU (ngā polyurethane wera-kirihou) ka honoa te āputa rauemi i waenga i ngā rapa me ngā kirihou. Nā ōna āhuatanga ā-tinana ka taea te whakamahi i te TPU hei rapa mārō me te wera-kirihou ngohengohe. Kua whānuitia te whakamahinga me te rongonui o te TPU i roto i ngā mano tini hua, nā te mea he pakari, he ngawari me te tae, me ētahi atu painga. Hei tāpiri, he ngāwari ki te tukatuka.
Hei rauemi hangarau-teitei hou, he rauemi hoa-taiao hoki, he maha ngā āhuatanga pai o te TPU pērā i te whānuitanga o te pakeke, te kaha miihini teitei, te ātete makariri tino pai, te mahi tukatuka pai, te pirau hoa-taiao, te ātete hinu, te ātete wai me te ātete pokepokea ai.

25KG/pēke, 1000KG/papa, 1500KG/papa rānei, papa kirihou tukatuka
Te Whakahaere me te Rokiroki
1. Āta karohia te hongi i ngā kohu me ngā kohu tukatuka wera
2. Ka taea e ngā taputapu whakahaere mīhini te hanga puehu. Āta karohia te hongi i te puehu.
3. Whakamahia ngā tikanga whakapūmau tika i te wā e whakahaere ana i tēnei hua hei karo i ngā utu hiko pūmau
4. Tērā pea ka pahekeheke ngā pirepire i runga i te papa, ā, ka taka pea
Ngā taunakitanga rokiroki: Hei pupuri i te kounga o te hua, rongoatia te hua ki te wāhi hauhautanga, maroke. Puritia ki roto i te ipu kua hiritia pai.
Ngā Tuhipoka
1. Kāore e taea te whakamahi i ngā rauemi TPU kua pirau hei tukatuka hua.
2. I mua i te whakahāngai, me maroke rawa, inā koa i te wā e whakahāngai ana i te extrusion, te whakahāngai pupuhi, me te whakahāngai pupuhi kiriata, me ngā whakaritenga pakari ake mō te nui o te makuku, inā koa i ngā wā haumākū me ngā wāhi haumākū teitei.
3. I te wā e hangaia ana, me whai whakaaro ki te hanganga, te ōwehenga kōpeketanga, te hohonutanga o te awaawa, me te ōwehenga āhua L/D o te tīwiri i runga i ngā āhuatanga o te rauemi. Ka whakamahia ngā tīwiri werohanga mō te werohanga, ā, ka whakamahia ngā tīwiri whakaputa mō te whakaputa.
4. I runga i te rere o te rauemi, whakaarohia te hanganga o te pokepokea ai, te rahi o te tomokanga kāpia, te rahi o te pūwero, te hanganga o te awa rere, me te tūranga o te putanga hau.
