He aha ngā rerekētanga matua o ngā hoahoa o te oko tīwiri mō ngā mahi pupuhi?

Kupu Whakataki

I roto i ngā ahumahi tukatuka kirihou hou, kua noho te hanga pupuhi hei tētahi o ngā tikanga hanga e whakamahia whānuitia ana mō te hanga pounamu, ipu, wāhanga motuka, tāke ahumahi, me ngā momo hua kirihou tuwhera. Ko te kounga me te whai huatanga o te hanga pupuhi e tino whakawhirinaki ana ki te mahi a te pūnaha whakaputa, inā koa te whirihoranga o te tīwiri me te oko.

He maha ngā kaihanga e aro nui ana ki ngā pūnaha whakaputa mīhini me te aunoatanga, engari e whakaiti ana i te hiranga o te hoahoa o te oko tīwiri. Ko te mea pono, ko te oko tīwiri te wāhanga matua e kawenga ana mō te kawe, te rewa, te pēhi, te whakakotahi, me te whakau i ngā rauemi kirihou i mua i te taenga o te rewa ki te pane o te mate.

He rerekē ngā āhuahanga tīwiri, ngā ōwehenga kōpeketanga, ngā ōwehenga L/D, ngā hanganga whakaranu, me ngā rauemi ātete-kakahu mō ngā whakamahinga rerekē o te whakakoi pupuhi. Mā te whiriwhiri i te whirihoranga oko tīwiri hē ka arahi pea ki te rere rewa kore pumau, te matotoru pakitara kāore i te ōrite, te nui rawa o te whakapaunga pūngao, te mutunga mata ngoikore, te tere rānei o te kakahu.

Mō ngā kaihanga e whai ana ki te whakapai ake i te pai o te whakaputa me te kounga o te hua, he mea nui kia mārama ki ngā rerekētanga matua o te hoahoa o ngā oko tīwiri.

Te Tūranga o ngā Pēra Tīwiri i roto i te Whakapūtanga Pupuhi

I roto i ngā mahi pupuhi whakarewa, ka rewa tonu te pūnaha whakaputanga, ka kawe i ngā rauemi kirihou ki roto i te parison. Kātahi ka pupuhihia te ngongo rewa ki roto i te kōhao pokepoke hei hanga hua tuwhera.

Ka pā tika te pūnaha oko tīwiri ki:

• Te ōritetanga rewa

• Te pumau o te pēhanga

• Te whakakirikiri rauemi

• Putanga whakaputa

• Te ōritetanga o te hua

• Te whai huatanga o te pūngao

• Te tere o te pirau rauemi

Mā te pūnaha oko tīwiri kua tino arotauhia ka pumau te tuku rewa me te hanganga parison ōrite, he mea nui ēnei hei pupuri i te tika o ngā āhuatanga.

Ngā Take Hoahoa Matua i roto i ngā Pēra Tīwiri Whakairoiro

1. Kōwhiringa Tauwehenga L/D

Ko te ōwehenga L/D e pā ana ki te whanaungatanga i waenga i te roa o te tīwiri me te whānui o te tīwiri. Mā tēnei ka whakatau te roa o te noho o te rauemi i roto i te oko.

Ka pai ake te roa o te noho:

• Te ōritetanga rewa

• Te ōritetanga o te pāmahana

• Te whakakirikiri rauemi

Heoi anō, ka piki ake pea ngā ōwehenga L/D nui rawa:

• Te whakapaunga pūngao

• Te wera kutikuti

• Te pirau o ngā rauemi

Ngā Taunakitanga Noa

Tono	Te ōwehenga L/D e taunakitia ana
Whakarewa Pupuhi Pounamu HDPE	24:1 – 30:1
Te Hanga Ipu Ahumahi	28:1 – 32:1
Te Tukatuka Rauemi Hangarua	20:1 – 24:1

I te nuinga o ngā pūnaha whakarewa pupuhi HDPE, e pai ake ana ki ngā kaihanga ngā ōwehenga L/D i waenga i te 24:1 me te 30:1 nā te mea ka whakaratohia he pumau rewa taurite me te whai huatanga o te whakaputa.

2. Hoahoa Tauwehenga Kōpeketanga

Ko te ōwehenga kōpeketanga e whakatau ana i te nui o te kōpeketanga o te rauemi i a ia e neke ana i roto i te tīwiri.

Ka kaha ake te kutikuti me te tere ake te rewa o ngā ōwehenga pēhanga teitei. Heoi, mā te pēhanga nui rawa ka puta:

• Te wera rawa

• Te pirau o ngā rauemi

• Pakaru rewa

• Rere kore pumau

Mō ngā mahi pupuhi whakarewa, ko ngā ōwehenga kōpeketanga ngawari te mea e hiahiatia ana.

Rauemi	Te Ōwehenga Kōpeketanga Noa
HDPE	2.5:1 – 3.0:1
PP	2.8:1 – 3.5:1
Kirihou Hangarua	2.0:1 – 2.5:1

Ko ngā kaihanga e tukatuka ana i ngā rauemi hangarua he iti ake te ōwehenga kōpeketanga hei whakaiti i te pirau wera.

3. Ngā Hanganga Tīwiri Ārai

Kua piki haere te rongonui o te hangarau tīwiri arai i roto i ngā pūnaha whakarewa pupuhi whakaputa hou.

He rerekē tēnei i ngā tīwiri noa, he rerekētanga anō kei roto i ngā tīwiri ārai hei wehewehe i te rauemi totoka mai i te kirihou rewa.

Ko ngā painga ko:

• He pai ake te whai huatanga o te rewa

• Ngā matūriki kāore i rewa kua whakaitihia

• Te pumau o te putanga kua whakapaitia

• Te hekenga o te pāmahana

• Te whakapai ake i te pumau o te hua

I roto i ngā raina whakaputa whakarewa pupuhi putanga teitei, ka taea e ngā tīwiri arai te whakapai ake i te ōritetanga rewa.

4. Te Whakaranu i ngā Wāhanga

Mā te whakaranu i ngā wāhanga ka pai ake te tohatoha pāmahana me te matotoru o te rewa.

Ko ngā hanganga whakaranu noa ko:

• Ngā mīhini whakaranu Maddock

• Ngā mīhini whakaranu porowhita

• Ngā mīhini whakaranu paināporo

Mā te hoahoa tika o te wāhanga whakaranu ka whakaitihia:

• Ngā rārangi tae

• Te hanganga o te kirikiri

• Te matotoru o te pakitara kāore i te ōrite

I roto i ngā mahi whakaputa maha, mā te tāpiri i tētahi wāhanga whakaranu ka tino whakapai ake i te kounga o te mata.

5. Āhua Rere Tīwiri

Ko te āhuahanga o te tīwiri e whakatau ana i te whanonga kawe me te whakaputa pehanga.

Ko ngā tawhā nui ko:

• Hōhonutanga rere

• Whānui rere

• Te rerekētanga o te oro

• Whakawhiti hohonutanga o te hongere

Ka whakapai ake ngā hoahoa rere hōhonu i te kaha kawe engari ka whakaiti i te pai o te rewa.

Ka whakanui ake te kutikuti me te pēhanga i ngā hanganga papaku engari ka tere ake te pakaru.

He mea nui te whakataurite i ēnei tawhā.

Kōwhiringa Rauemi o te Pēra

He maha ngā wā ka tukatukahia e ngā raina pupuhi-whakakikorua ngā rauemi whakakoi, ngā rauemi hangarua rānei.

Na reira, ko te whiriwhiri i ngā rauemi mō te hanga i te oko ka tino pā ki te roa o te ora o te oko.

Ngā Rauemi Pēra Noa

Rauemi	Ngā Āhuatanga
Rino Koranu Nitrided	He pakari pai, he iti te utu
Pēra Whakarewa-rua	He ātete kakahu pai rawa atu
Paninga Carbide Tungsten	Ātete pai rawa atu ki te pakū

He whānuitia te whakamahinga o ngā oko bimetallic i roto i ngā tono putanga teitei nā te mea he tino roa.

Te Pānga o te Hoahoa Tīwiri ki te Kounga o te Hua

Te Pūmautanga o te Matotoru o te Pakitara

Ko te rere koretake o te wai rewa ka hua ake te tohatoha kore taurite o te pakitara.

Mā te āhuahanga tīwiri kua arotauhia ka āwhina ki te pupuri i te pēhanga pumau i te wā e hangaia ana te parison.

Whakaotinga Mata

Ko te whakaranu koretake, te werawera rānei ka hua ake i ēnei mea:

• Ngā tohu wera

• Ngā rārangi rere

• Te taratara o te mata

Mā ngā wāhanga rewa pai ake ka whakaitihia ēnei hapa.

Te Whai Hua o te Whakaputa

Ka whakaitihia e ngā hoahoa tīwiri whai hua:

• Te wā tīmatanga

• Te whakapaunga pūngao

• Te tere para

Ka whakapai tika tēnei i te hua.

Ngā Raru Noa i Puta Mai i te Hoahoa Tīwiri Hē

Raruraru	Take Pea
Putanga Kore-pūmau	Te ōwehenga kōpeketanga hē
Ngā hapa o te mata	Wāhanga whakaranu ngoikore
Te Whakahekenga Rauemi	Te wera nui rawa o te kutikuti
Putanga Iti	Kāore i te rawaka te pai o te kawe waka
Te kakahu tere	Te kōwhiringa rauemi kāore i te rawaka

Ngā Tohutohu Whakapaipai mō ngā Pēra Tīwiri Whakairoiro

Whakatauritehia te Hoahoa o te Tīwiri ki te Rauemi

He rerekē ngā āhuatanga kutikuti me te rewa e hiahiatia ana e ngā rauemi rerekē.

Aroturukihia te Mahana

Ko te piki me te heke o te pāmahana tētahi o ngā tino take o te kore pumau.

Whakamahia ngā rauemi ātete-mau

Ko ngā tono whakakī-nui me kaha ake te ātete ki te kakahu.

Arotauhia te Tere o te Tīwiri

Ka nui ake pea te hekenga me te kore pumau o te pehanga i te nui rawa o te RPM.

Ngā Auahatanga o te Ao kei te heke mai i roto i te Hoahoa o ngā Tīwiri Whakairoiro

Ko te hanga hangahanga pupuhi hou e aro nui ana ki:

• Te whai huatanga o te pūngao

• Te tukatuka rauemi hangarua

• Ngā pūnaha aroturuki atamai

• Te whakaputanga hua-teitei

• Ngā utu tiaki iti

Ka haere tonu te whanake o te hangarau oko tīwiri matatau hei tautoko i ēnei tono.

Whakamutunga

He mea nui te hoahoa o te oko tīwiri ki te kounga me te whai huatanga o te whakaputa pupuhi whakarewa.

Me āta arotau ngā āhuatanga pēnei i te ōwehenga L/D, te ōwehenga kōpeketanga, te hanganga whakaranu, te āhua o te tīwiri, me ngā rauemi ātete-kakahu, kia rite ki ngā whakaritenga tono.

Ka taea e ngā kaihanga e haumi ana ki ngā otinga oko tīwiri kua whakaritea me te tono motuhake te whakatutuki i:

• He pai ake te pumau o te hua

• Ngā reiti para kua whakaitihia

• Te roa o te ora o ngā taputapu

• Te whakapai ake i te whai huatanga o te pūngao

• Te pumau o te whakaputanga

Mō te hanga whakarewa pupuhi o ēnei rā, kāore e tika ana ngā pūnaha oko tīwiri kua arotauhia—he mea nui tonu.
