Ngā Pātai Auau

He aha te take e pakaru wawe ai ngā peera o te motuka hiko?

Ko te pakaru o te peera i roto i ngā motuka hiko i te nuinga o te wā ka puta mai i te korenga o te hinu whakahinuhinu (50% o ngā take), te urunga mai o te poke (20%), te whakaurunga hē (15%), me te kino hiko (10%). Ko ētahi atu take he hapa rauemi, he hē rānei te tūnga. Ko te nuinga o ngā pakaru ka taea te ārai ko te whakahinuhinu auau, te whakahaere tika i te wā tāutanga, me te whiriwhiri peera hiri mō ngā taiao uaua.

Kia pēhea te auau o te whakakapinga o ngā peera o te motuka?

Ko ngā wā whakakapinga peara motuka ka whakawhirinaki ki ngā āhuatanga whakahaere, ngā āhuatanga kawenga, me ngā mahi tiaki. I raro i ngā āhuatanga pai e tutuki ana i ngā whakaritenga a te kaihanga, ka tutuki i ngā peara pōro hohonu teNgā whakatauranga ora o te L10 o te 20,000 ki te 50,000 hāoraMā ngā kaupapa aroturuki āhua ka taea ngā whakatau whakakapinga e ahu mai ana i ngā raraunga, kaua i te whakaritenga e ahu mai ana i te maramataka.

Ka taea te whakamahi anō i ngā peera motuka i muri i te tangohanga?

Kāore i te tūtohutia kia whakamahia anō ngā peera. Ka kino pea ngā mata o te ara rere, ngā wāhanga hurihuri, me ngā wāhanga o te whare herehere i ngā tukanga tango. Kāore e taea e te tirotiro ā-kanohi te kite i ngā kino o te ngenge o raro i te mata. He nui ake te mōrearea o te pakaru o ngā peera e whakamahia anōtia ana ki ērā o ngā tāutanga hou.

He aha te rerekētanga i waenga i ngā peera motuka hiri me ngā peera motuka tuwhera?

Kei roto i ngā peera hiri he parenga whakauru, he hiri rānei i tētahi taha, i ngā taha e rua rānei, hei tiaki i te poke me te pupuri i te hinu whakahinuhinu i roto i te kōhao peera. Me whakarato he hinu whakahinuhinu o waho mō ngā peera tuwhera, ā, ka pai mō ngā tono ina taea te whakahinuhinu anō i ngā wā katoa. Ko ngā peera hiri te nuinga o ngā tono mō ngā motuka hiko nā te ngāwari o te tiaki me te ātete ki te poke.

Me pēhea taku whakatau i te rahi tika o te peera mō taku motuka hiko?

Ko te whiriwhiri i te rahi o te peera e whai ana i ngā tātaitanga hoahoa miihini i runga i te diameter o te pou, ngā whakaritenga kawenga, me ngā āhuatanga tere. Ko ngā rahi anga motuka te tikanga e whakatau ana i ngā whakaritenga peera paerewa e ai ki te IEC 60072. Mō ngā tono kore-paerewa, tatauhia te kawenga hihiri ōrite mā te whakamahi i ngā tātai ISO 281, kātahi ka tīpako i tētahi peera me te whakatauranga kawenga hihiri taketake (C) e whakarato ana i te tawhē haumaru e tika ana—i te nuinga o te wāC/P ≥ 4mō ngā tono whānui mō ngā motuka.
