Ka hangaia te pepa kraft mā te tukanga whakamomona, e whakarite ana kia tino tika te pepa kraft mō tōna whakamahinga. Nā te mea kua piki ake ngā paerewa mō te ātete pakaru, te haehae, me te kaha kume, tae atu ki te hiahia kia whakaitihia te pakari me te tino nui o te pore, he nui ngā whakaritenga mō te pepa kraft kounga teitei mō te tae, te kakano, te ōritetanga, me te uara ataahua.
Hei whakatutuki i ngā paerewa tae me te kounga ataahua, me whakamā te penupenu kia eke ki te kanapa i waenga i te 24% me te 34%, me te pupuri tonu i ngā uara kōwhai me te whero o te penupenu, arā, kia mau tonu te pakari o te penupenu mā.
Te tukanga hanga pepa Kraft
Ko te tukanga hanga pepa kraft e whai ake nei:
1. Te hanganga o ngā rauemi mata
He rite tonu te momo tukanga hanga pepa katoa, engari ko te kounga anake, te matotoru, me te tāpiri i ngā āhuatanga tāpiri he rerekē. He mea hanga te pepa kraft mai i te penupenu rakau muka roa, ā, he teitei ake te whakatauranga āhuatanga ā-tinana. Ka puta mai i te tukanga he ranunga o te penupenu rakau ngohengohe me te penupenu rakau mārō e tutuki ana i ngā paerewa kounga hangarau mō te pepa kraft kounga teitei. Tata ki te 30% o te katoa o te hanga ko te penupenu rakau whānui. Kāore he pānga o tēnei ōwehenga rauemi mata ki te kaha ā-tinana o te pepa, engari he pānga nui ki te kanapa me ētahi atu paearu.
2. Te tunu kai me te whakama
Me iti ake ngā paihere muka matotoru o te penupenu Kraft, ā, me ōrite te tae, me te tutuki hoki i ngā whakaritenga mō ngā tikanga tunu kai me te whakamaene kounga teitei. E whakaaetia whānuitia ana he rerekē te pai o te tunu me te whakamaene i waenga i ngā tauira rakau. Mena ka taea e te raina penupenu te wehewehe i te penupenu rakau ngohengohe me te rakau pakeke, ka taea te whiriwhiri i te tunu me te whakamaene rakau ngohengohe me te rakau pakeke. I tēnei wāhanga ka whakamahia te tunu kai koniferous me te rakau pakeke, me te whakamaene whakakotahi i muri i te tunu. I roto i te tukanga hanga, he mea noa ngā hapa kounga pēnei i te koretake o ngā paihere muka, ngā paihere muka matotoru, me te tae penupenu koretake.
3. Te pēhi
He taahiraa nui te whakapai ake i te tukanga hanga penupenu ki te whakapiki i te pakari o te pepa kraft. I te nuinga o te wā, me whakanui ake te pēhanga o te penupenu me te pupuri tonu i tōna porous pai me te iti o te pakari hei whakapai ake i te pakari, te mātotoru, me te ōritetanga o te pepa.
He nui ake te kaha o te pepa kraft, ā, he nui ake ngā hapa ka taea te ine i ngā peka poutū me ngā peka taha. Nō reira, ka whakamahia ngā ōwehenga tika o te penupenu ki te whānui o te pepa, ngā mea whakangaueue mata, me ngā mea hanga tukutuku hei whakapai ake i ngā māka. Ko te tikanga pēhi e whakamahia ana hei hanga i te pepa ka pā ki tōna urunga hau, tōna pakari, me tōna maeneene. Mā te pēhi ka whakaitihia te porosity o te pepa, ka whakaitihia tōna urunga me tōna korehau, me te whakanui ake i te hiri; ka taea hoki e ia te whakanui ake i te kaha ā-tinana o te pepa.
Koinei ngā huarahi e hangaia ai te pepa kraft.
