Te Ine i te Kukū o te Pulp
Ko te kukū o te penupenu i roto i te pouaka mīhini e eke ana ki te 2.5–3.5% i te nuinga o te wā. Me wai hei whakaiti i te kukū o te penupenu kia pai ai te horapa o ngā muka me te tango i ngā poke.
Mōngā mīhini fourdrinier, ko te kukū o te penupenu e uru ana ki te mata he 0.3–1.0% te tikanga, e ai ki ngā āhuatanga o te penupenu, ngā āhuatanga o ngā taputapu, me te kounga o te pepa. I tēnei wā, ko te taumata o te waimeha e rite ana ki te kukū penupenu e hiahiatia ana i runga i te mata, ko te tikanga ko te kukū kotahi e whakamahia ana mō te purenga, te tātari, me te hanga i runga i te mata.
Ko te kukū o te penupenu i runga i te mata he iti iho i te 0.1–0.3% mō ngā mīhini rango anake. He teitei ake te tere rere mā roto i te purenga me te tātari i ngā whakaritenga mō ēnei penupenu iti-kukū. Hei tāpiri, me nui ake ngā taputapu purenga me te tātari hei tukatuka i te penupenu iti-kukū, e hiahia ana ki te nui ake o te pūtea, te wāhi nui ake, ngā paipa uaua ake, me te nui ake o te whakapaunga pūngao.
He maha ngā wā ka whakamahia e ngā mīhini rango hetukanga whakaranu e rua-wāhanga,ka whakaitihia te kukū ki te 0.5~0.6% i te tuatahi hei purenga tuatahi me te tātari; kātahi ka whakaitihia ki te kukū ūnga i mua i te whakauru ki te mata i roto i te pouaka whakau.
Ko te wai mā te wai mā te whakakōkī penupenu ka whakamahia mā roto i te kupenga hei tiaki wai me te whakaora i ngā muka angiangi, ngā whakakī, me ngā matū mai i te wai mā. He painga te whakaora wai mā ki te tiaki pūngao mō ngā mīhini e hiahia ana ki te whakamahana penupenu.
Ngā Take Matua e Pā Ana ki te Kukū o te Pulp Kua Whakarewahia
Ngā Rerekētanga o te Kukū o te Pulp e Tomo Ana ki te Pouaka Whakahaere
Ka rerekē pea te kukū o te penupenu i te pikinga o te matotoru o te kiri nā te pikinga o te matotoru o te kiri, nā te rerekētanga rānei o te pūnaha pakaru. Mā te koretake o te tohanga toto i roto i ngā pouaka mīhini ka rerekē pea te kukū o te penupenu puta noa i ngā wāhi rerekē, ka nui ake te kore pumau.
Rere Whakamuri o te Whakakores i rotoTe purenga me tetātari
Ko te para mai i te purenga me te tātari ka whakahokia mai ki roto i te pūnaha me te wai whakakōkī. Ko ngā rerekētanga o te rōrahi me te kukū o tēnei para ka whakawhirinaki ki te mahi a ngā taputapu purenga me te tātari me ngā taumata wai i ngā putanga papu.
Ka pāngia te kukū wai mā e whakamahia ana mō te whakawaiwaitanga e ēnei panoni, ā, ka pāngia hoki te kukū penupenu whakamutunga. Tērā pea ka puta ngā raruraru ōrite i roto i ngā pūnaha whakahoki o ngā tāke waipuke mīhini rango.
Ka pāngia te mahi a te mīhini pepa me te kounga o te pepa whakamutunga e ngā rerekētanga o te kukū o te penupenu kua whakakōkīhia. Nō reira, he mea nui kia aro turukihia te kukū o te penupenu me tepenupenu ine ōritetangai hangaia eMita Ronai te wā whakaputa me te whakarerekē i te rerenga mai ki te pouaka whakahaere kia mau tonu ai te pumau o ngā kukū. He maha ngā wā ka whakamahia e ngā mīhini pepa hou ngā taputapu aunoa hei:
- Whakatikatika aunoa i tete kukū o te penupenute tomo ki te pouaka whakahaere.
- Whakatikatikahia te rerenga mai i runga i ngā panonitanga o te taumaha pepa mete kukū o te penupenu o te pouaka upoko.
Mā tēnei ka pumau te kukū o te penupenu.
Ngā Hua o te Whakarerekētanga Kukū mō te Pulp Kua Whakarewahia
Ko te whakahaere i te kukū o te penupenu kua waimeha he painga mō te mahi tino pai o te mīhini pepa me te pupuri i te kounga o te pepa.
Mō ngā Mīhini Puoto
Ina iti te kaha o te patu o te penupenu, ā, ka tere te mimiti o te wai, ka heke te taumata wai o roto, o waho hoki i te wāhanga mata, ka ngoikore te piri o te paparanga pepa ki te mata. Ka whakanui ake tēnei i te pānga kukū, ka whakaiti i te waipuke, ā, ka whakanui ake i te rerekētanga tere i waenga i te penupenu me te mata, ka hua ake te hanganga pepa kāore i te ōrite.
Hei whakatika i tēnei, ka whakanuia te whakamahinga o te wai mā hei whakaiti i te kukū o te penupenu, ka whakapiki ake i te tere rere ki te mata. Ka whakanuia e tēnei te rerekētanga o te taumata wai, ka whakanui ake i te waipuke, ka whakaiti i ngā pānga kukū, ā, ka whakaitihia ngā rerekētanga tere, ā, ka whakapai ake i te ōritetanga o te pepa.
Mō ngā Mīhini Fourdrinier
Ka uaua te rere o te wai i ngā nekehanga whiu teitei, ka roa ake te raina wai, ka nui ake te makuku o te pepa mākū, ā, ka puta he whakairo, he kuru rānei i te wā e pēhi ana. Ka iti haere te taumahatanga o te pepa puta noa i te mīhini, ā, ka nui ake te mimiti i te wā e whakamaroke ana, ka puta he hapa pēnei i te kopa me te kita.
Hei whakakore i ēnei wero, ka taea te whakanui ake i te kukū o te penupenu kua whakaranua mā te whakaiti i te whakamahinga o te wai mā, hei whakamama i ngā raruraru rerenga wai.
I tetahi atu taha, ki te iti te kaha o te whiu, ka rere ngā muka, ā, ka tere rawa te mimiti i runga i te mata, ka pā ki te ōritetanga o te pepa. I tēnei wā, mā te whakanui ake i te whakamahinga o te wai mā hei whakaiti i te kukū o te penupenu kua whakaranua ka taea te whakaiti i te rere o te pepa, me te whakapai ake i te ōritetanga.
Whakamutunga
He mahi tino nui te whakakōkī i roto i te hanga pepa. I roto i te whakaputanga, he mea nui kia:
- Aroturukihia me te whakahaere pūmau i ngā huringa o te waimehate kukū o te penupenukia pumau ai ngā mahi.
- Kia aro ki ngā panonitanga o te kounga o te hua me ngā tikanga whakahaereā, mēnā e tika ana, whakatikatika i te kukū o te penupenu hei taputapu hei whakakore i ngā uauatanga pēnei i ngā mea kua whakahuatia i runga ake nei.
Mā te whakahaere tika i te waimehatanga o te penupenu, ka taea te whakatutuki i te whakaputanga pumau, te pepa kounga teitei, me te mahi tino pai.
