1. He rereke te tukanga hoahoa mo te pupuhi, ko te hoahoa mo te pupuhi he wero + te pupuhi;Ko te werohanga ko te werohanga + te pehanga;Roll niao he extrusion + pēhanga;Me waiho te mahunga o te pupuhi i te putorino momi, me whai waahanga kuaha te werohanga, me whai burr te tapahi kirihou hurihuri.
Hoahoa mate pupuhi pupuhi
2. I te nuinga o te korero, he mea totoka te werohanga werohanga, ko te pupuhi pupuhi me te hanga pukapuka he matua kau.He kanapa te mata o nga wahanga werohanga, he pahekeheke te mata kirihou o te pupuhi me te huri.Whakatauritea te pupuhi me te whakakoi mo te whakakoi i te iti rawa o te pupuhi pupuhi he waha pupuhi.He whakataurite whanui tenei.Ka whakaaro ahau mehemea ka marama koe!!
3. Te whakahekenga o nga kirihou me ona ahuatanga whakaawe
Ko nga Thermoplastics te mana o te roha ina whakamahana, ka paheke ina whakamatao, me te mea ka heke ina pehia.I roto i te tukanga o te werohanga, ka werohia te kirihou whakarewa ki roto i te kohanga pokepoke, i muri i te whakakī, ka whakamataohia te whakarewa me te pakari, ka puta te whakaheke i te wa e tangohia ana nga waahanga kirihou i roto i te pokepoke, e kiia ana ko te hanga i te whakaheke.Ko nga waahanga kirihou mai i te pokepoke ki te pumau o tenei waa, ka iti tonu te whakarereketanga o te rahi, ko te whakarereketanga ko te haere tonu ki te whakaheke, ka kiia tenei whakahekenga i muri i te whakaheke.Ko tetahi atu rereke ko te roha o etahi kirihou hygroscopic na te kaha o te makuku.Hei tauira, ka 3% te nui o te wai o te nylon 610, ka 2% te piki o te rahi;A, no te te ihirangi wai o te muka karaihe te nairona 66 he 40%, ko te 0.3% te whakanui i te rahi.Engari ko te hanga whakaheke he mahi nui.
