Ka hurahia e ngā Utauta Hinu a Landrill te Aratohu Kōwhiri Pūtaiao mō ngā Mono Piriti Whakarewa

I roto i te ao uaua o ngā mahi mara hinu, ko te whiriwhiri i te mea tikamono piriti rewaHe mea nui tēnei mō te hanganga me te whakaputanga pai o te puna. Kua whakaurua mai e Landrill Oil Tools tētahi aratohu whiriwhiri whānui e ahu mai ana i te rākau whakatau, hei whakahaere i te tukanga mō ngā tohunga o te umanga.

Hipanga 1: Taurite Rauemi e Ārahihia ana e te Pāmahana

Ko te pāmahana hanganga te mea matua tuatahi. Mā tēnei ka whakatau te pumau o te wera me te tere whakarewa o ngā rauemi mono piriti. Mō ngā taiao pāmahana iti (i raro i te 60℃), he pai ngā tauira Paheke Kotahi, Paheke Takirua rānei pēnei i a LZ001, LZ002, me LZ022. He iti ngā rahinga o ēnei (roa ≤ 330mm) me te tere whakarewa (20 – 40mg·cm⁻²·h). I ngā āhuatanga pāmahana reo (60 – 90℃), he kanapa ngā mono Paheke Takirua, Paheke Takirua rānei pēnei i a LZ008, LZ016, me LZ027, e whakarato ana i te pumau punga pai ake mō ngā āhuatanga pēhanga reo (≤ 70MPa). Ko ngā puna pāmahana teitei (i runga ake i te 90℃) e hiahia ana ki ngā otinga Paheke Takirua, Whakarewa Katoa rānei pēnei i a LZ025, LZ030, me LZ031, e whakamanamana ana ki te ātete pēhanga teitei (85MPa) me te ātete waikura whakarewa katoa.

Hipanga 2: Te Whakarerekētanga ki te Tote me te Waikura

Ka whakawhāitihia ake ngā kōwhiringa e ngā taiao tote (kukū Cl⁻) me te waikura. He pai ngā puna tote iti (i raro i te 500mg/L) mō te Raupapa LZ001/LZ002, me te tere whakarewa o te 20 – 40mg·cm⁻²·h. I ngā tautuhinga tote teitei (neke atu i te 15000mg/L), ko te Raupapa LZ025/LZ028 te mea matua, me te tere whakarewa o te 80 – 120mg·cm⁻²·h. Mō ngā taiao waikawa (pH ≤ 3), e taunakihia ana te Raupapa Full Metal LZ030, nā tōna paninga ātete waikawa me te tere whakarewa o te 20 – 300mg·cm⁻²·h i ngā pāmahana teitei.

Hipanga 3: Ngā Whakaaro mō te Whakatakotoranga me te Pēhanga

He mea nui anō hoki te rahi o te anga me te pēhanga hanganga. He pai te hono o ngā anga iti (≤ 4″) ki te Single Slip LZ001 (OD 89mm). Ka whai hua ngā mahi pēhanga teitei (neke atu i te 70MPa) mai i te Double Slip LZ025 (Pēhanga 85MPa), he hoahoa paheke rua-aronga mō te kaha kutikuti 30% teitei ake. Mō ngā anga kua whakapōturitia, ka whakarite te Compacted Double Slip LZ022 (OD 110mm) i te āheinga ki te uru ki roto i ngā anga 4.5″.

Mā te whai i tēnei rākau whakatau, ka taea e ngā tīma o te mara hinu te whiriwhiri tika i ngā mono piriti ka taea te rewa, me te arotau i te mahi a te puna, me te whakarite kia maeneene te mahi puta noa i ngā āhuatanga whenua rerekē. Mā te aratohu a Landrill Oil Tools ka whakamanahia te umanga ki te whakatau i ngā wero puna uaua me te tika pūtaiao.
