He aha ngā Whakaaroaro Matua mō te Hoahoa mō ngā Pēra Tīwiri i roto i ngā Mahi Whakapūpū?
Kupu Whakataki
I roto i te hanga whakarewa pupuhi, he mea nui te hoahoa o te oko tīwiri ki te whakatau i te kounga rewa, te pai o te whakaputa, me te ōritetanga o te hua whakamutunga. He rerekē ki ngā whakamahinga whakaputa whānui, me whai rere rewa pumau te whakarewa pupuhi, me te whakahaere pāmahana tika, me te tohatoha rauemi ōrite kia rite ai te hanganga o te parison.
Mā te mārama ki ngā āhuatanga matua o te hoahoa o ngā oko tīwiri ka āwhina i ngā kaihanga ki te arotau i te mahi me te whakaiti i ngā mōrearea whakahaere.
1. Te Whai Hua o te Whāngai Rauemi me te Kawe
Ko te wāhanga tuatahi o te oko tīwiri te kawenga mō te kawe rauemi totoka.
Ngā Take Matua:
- Te hohonutanga o te wāhanga whāngai
- ōwehenga kōpeketanga
- Te maimoatanga mata o te oko
Mā te wāhanga whāngai i hangaia tika ka pumau te urunga rauemi, ka iti ake te hononga, ā, ka rite tonu te tere putanga. Mā te hohonu o te rere ka pai ake te kaha kawe, engari mā te hohonu rawa ka whakaiti i te pai o te rewa.
2. Te Mahi Rewa me te Pūmautanga Wera
I roto i te hangahanga pupuhi, ka pā tika te ōritetanga o te rewa ki te whakahaere i te matotoru o te pakitara me te kounga o te mata o te hua.
- Ōwehenga L/D (Ōwehenga Roa-ki-Te-Diameter)
- Ngā hanganga tīwiri ārai
- Te whakaranu i ngā wāhanga
Ko te ōwehenga L/D teitei ake ka pai ake te ōritetanga o te rewa engari ka roa ake te noho. Ka whakarei ake ngā hoahoa tīwiri arai i te pai o te rewa me te ārai i te wera nui.
Mō te whakarewa pupuhi HDPE, ko te ōwehenga L/D kua arotauhia i waenga i te 24:1 me te 30:1 te mea e whakamahia whānuitia ana i runga i ngā whakaritenga putanga.
3. Te Āhuahanga o te Tīwiri me te Hoahoa Kōpeketanga
Ko te āhua o te tīwiri e whakatau ana i te tere kutikuti me te hanga pēhanga i roto i te oko.
- ōwehenga kōpeketanga
- Papa rere
- Te rerekētanga o te hohonutanga o te hongere
Ka pai ake te rewa o ngā ōwehenga pēhanga teitei ake, engari ka piki ake pea te pirau o ngā rauemi mēnā kāore e tika te whakahaere. He mea nui te pēhanga taurite mō te hanganga parison pumau me te mutunga mata maeneene.
4. Te Kōwhiringa Rauemi me te Ātete ki te Mau
He maha ngā wā ka tukatukahia e te pupuhi whakarewa ngā rauemi whakakoi, ngā rauemi kua whakakīia rānei, ā, he mea tino nui te ātete ki te kakahu mō te whakamahinga roa.
- maitai koranu nitrided
- Ngā oko whakarewa-rua
- Ngā paninga ātete-mau
Mā te whakamahi i ngā koranu pakeke-tiketike, i ngā arai bimetallic rānei, ka roa ake te ora o te mahi i raro i ngā āhuatanga putanga teitei.
5. Te Āhua o te Hoahoa ki te Mahi Whakaputa
| Tauwehenga Hoahoa | Pānga Whakaputa | Mōrearea mēnā kāore i hoahoatia pai |
|---|---|---|
| Te ōwehenga L/D iti | Kāore i te rawaka te rewa | Te koretake o te ōritetanga o te pakitara |
| Te Pehitanga Nui rawa | Te wera kutikuti teitei | Te pirau o ngā rauemi |
| Ātete Werawera | Te roa o te ratonga | Te whakanui ake i te wā kore mahi |
| Te Whakaranu Kino | Te koretake o te rewa | Ngā hapa o te mata |
Ngā Tohutohu Arotau Whaihua
- Tātaitia te ōwehenga kōpeketanga ki te momo rauemi (HDPE, PP, PETG).
- Āta karohia te kutikuti nui rawa i te wā e tukatuka ana i ngā rauemi hangarua.
- Whakaarohia te hoahoa o te tīwiri ārai kia nui ake ai te ōritetanga o te rewa.
- Kōwhiria ngā rauemi ātete ki te pakaru kia roa ai te wā e whai hua ai.
- Aroturukihia i ia wā te pāmahana me ngā ia o te pēhanga o te rewa.
Whakamutunga
Ehara te hoahoa o te oko tīwiri mō te whakakoi pupuhi i te otinga kotahi mō te katoa. Mā te taurite i waenga i te pai o te kawe, te mahi rewa, te whakahaere pēhanga, me te ātete ki te kakahu ka pumau te hanga me te kounga hua pai ake.
Mō ngā otinga oko tīwiri kua whakaritea mō ngā rauemi me ngā whakaritenga putanga motuhake, he mea nui te mahi tahi me tētahi kaihanga mātau.
