Me pēhea te whakapai ake i te ōritetanga rewa i roto i ngā tukanga tango kirihou
Kupu Whakataki
I roto i te hanga kirihou whakaputa, ko te ōritetanga o te rewa tētahi o ngā mea tino nui e pā ana ki te kounga o te hua. Ki te kore e ōrite te rewa, ka hua ake he hapa o te mata, he koretake te āhua, me te pikinga o ngā para.
I roto i te nuinga o ngā take whakaputa tūturu, ehara i te mea ko ngā rauemi mata anake te take o ēnei raruraru, engari ko te hoahoa hē o te oko tīwiri me te whirihoranga tukanga.
Mā te arotau i ngā tawhā matua pēnei i te āhua o te tīwiri, te ōwehenga L/D, me te whakahaere pāmahana, ka taea e ngā kaihanga te whakapai ake i te pumau o te rewa me te whai huatanga o te whakaputa.
---1. Arotauhia te ōwehenga L/D mō te wā noho pai ake
Ko te ōwehenga L/D (ōwehenga roa-ki-te whānui) e whakatau ana i te roa o te noho o te rauemi i roto i te oko, ā, he pānga tika tēnei ki te kounga rewa.
Mā te ōwehenga L/D teitei ake ka roa ake te wā mō te whakawhiti wera me te whakaranu, ka pai ake te ōritetanga o te rewa. Heoi, mā te roa rawa ka nui ake te wera kutikuti me te whakapaunga pūngao.
Ngā Taunakitanga Tauwehenga L/D Noa
| Tono | Te ōwehenga L/D e taunakitia ana | Painga Matua |
|---|---|---|
| HDPE Pupuhi Whakarewa | 24:1 – 30:1 | Rere rewa pumau |
| Te Whakaputa Paipa PVC | 22:1 – 26:1 | Kutikuti whakahaeretia |
| Ngā Rauemi Hangarua | 20:1 – 24:1 | Te whakaiti i te pirau |
Mō ngā whirihoranga tīwiri kua whakaritea ake, tirohia ā mātou ngā otinga oko tīwiri.
---2. Whakapai ake i te Whakaranu mā te Ārai me ngā Wāhanga Whakaranu
Me whai wāhi te wehenga me te whakakotahitanga whai hua o ngā āhua totoka me ngā āhua rewa ki te rewa ōrite. Koinei te wāhi e tino hira ai te hoahoa o te tīwiri.
Ka whakauruhia e ngā hanganga tīwiri arai tētahi rerenga atu e wehewehe ana i te rauemi totoka mai i te kirihou rewa, e taea ai te whakahaere pai ake i te rewa.
E ai ki ō mātou wheako, mā te tāpiri i tētahi wāhanga whakaranu ka taea te whakaiti i ngā matūriki kāore anō kia rewa mā te neke atu i te 20% i roto i ngā raina whakaputanga putanga teitei.
---3. Whakahaerehia te Āhua Pāmahana puta noa i te Pēra
Ko te rerekētanga o te pāmahana tētahi o ngā tino take o te kore pumau o te rewa.
Mā te pumau o te pāmahana ka āta rewa, ā, ka ārai i te wera nui o te rohe.
- Kia mau tonu ngā rohe whakamahana ōrite
- Ārai i ngā pikinga ohorere o te pāmahana
- Aroturuki tonu i te pāmahana rewa
Mō te tukatuka PVC, ahakoa ngā piki me ngā heke iti (±5°C) ka pā nui ki te kounga rewa.
---4. Whakatauritehia te Hoahoa o te Tīwiri ki ngā Āhuatanga o te Rauemi
He rerekē ngā taumata kutikuti, te pēhanga, me te roa o te noho e hiahiatia ana e ngā rauemi rerekē.
| Rauemi | Hoahoa i Manakohia | Whakaaro Matua |
|---|---|---|
| HDPE | Pehitanga taurite | Rere pumau |
| PVC | Hoahoa kutikuti iti | Ārai i te whakahekenga |
| Kirihou Hangarua | He iti te pēhanga + he pūhaumātao | Whakaitihia te pānga o te poke |
He mea nui te whiriwhiri i te whirihoranga tika mō te pumau mō te wā roa. Ako atu mō ngā otinga kua arotauhia i Paetukutuku mana o Jinteng Machinery.
---5. Āraia ngā hapa hoahoa noa
Ahakoa he pai ngā rauemi, ka taea e ngā kōwhiringa hoahoa kino te arahi ki te kounga rewa koretake.
- Te ōwehenga kōpeketanga teitei rawa → te wera kutikuti nui rawa
- He iti rawa te ōwehenga L/D → rewa kāore i oti
- Hoahoa whakaranu ngoikore → tohatoha rauemi koretake
Ko te whakataurite i ēnei āhuatanga te mea nui ki te whakatutuki i ngā hua ōrite.
---Ngā Pātai Auau: Te Rewa ōrite i roto i te Whakaputa
He aha te ōritetanga rewa i roto i te whakaputanga kirihou?
E pā ana tēnei ki te ōritetanga o te rewa me te whakaranu o te rauemi i mua i te putanga mai i te mate.
He aha te ōwehenga L/D pai rawa atu mō te extrusion?
Ko te nuinga o ngā tono e whakamahi ana i te 24:1 ki te 30:1, i runga i ngā whakaritenga rauemi me te putanga.
Me pēhea te whakaiti i ngā matūriki kāore anō kia rewa?
Mā te whakamahi i ngā tīwiri ārai me te whakapai ake i ngā wāhanga whakaranu ka tino whakaiti i ngā rauemi kāore anō kia rewa.
Ka pā te pāmahana ki te ōritetanga o te rewa?
Āe, ko te pāmahana kore pumau tētahi o ngā tino take o te koretake o te rewa.
---Whakamutunga
Hei whakapai ake i te ōritetanga rewa i roto i te whakaputanga kirihou, me whai huinga o te hoahoa tīwiri kua arotauhia, te kōwhiringa ōwehenga L/D tika, me te whakahaere pāmahana pumau.
Mā te whirihoranga tika, ka taea e ngā kaihanga te whakaiti i te auau para, te whakapai ake i te kounga o ngā hua, me te whakatutuki i te whakaputanga pumau ake.
Mō ngā otinga oko tīwiri kua whakaritea kia rite ki ō rauemi me ō tono, ka taea e te mahi tahi me tētahi kaihanga mātau te hanga i tētahi rerekētanga nui.
