Raina Pahu Hoist Maina (Rauemi PE/PP) – Mama, Ātete-Kakahu me te Tiakitanga Kakariki
Ngā Painga Matua
✅ Rauemi PE/PP Hoa-Taiao, Mahi Taurite
He mea hanga ki te polyethylene kiato-teitei (HDPE) te polypropylene rānei (PP), he iti te kiato (0.9-0.97g/cm³), he 60% te mama ake i ngā arai whakarewa, e whakaiti ana i te kawenga o te pahu.
He mata kua whakarerekētia me te pakeke o Shore D 70-80, he ātete kakahu 3-5x teitei ake i ngā kirihou paerewa, he pai mō ngā taiao maina makuku/pūehu.
✅ Ngā Putanga Pikopiko + Ngā Tauira Auau (Mai i ngā Whakaahua Tuturu)
Rengā whakamātautau "ngā pūwero kua whakaritea kia rite" (te teitei 50mm × te teitei 10mm) e kitea ana i te Whakaahua 3, e whakanui ana i te horahanga pa ki ngā taura waea me te pānga marara
Ngā tauira taimana/whakarara ārai-paheke i pēhia ki te mata, kua whakapūmautia te tauwehenga waku ki te 0.2-0.3 hei ārai i te paheke o te taura.tāruarua
✅ Whakaaturanga Kakariki Ataahua + Ngāwari te Tiaki
Tae kakariki kanapa ā-ahumahi (Pantone 17-6030 TPG) hei tere kite i ngā wāhi pakaru (e whakaaturia ana i ngā raina whakarārangi o te Whakaahua 3)
Ngā whitiki whakarara + ngā pūtu mā (M12) he whakapiri takirua (mō ia tāutanga Whakaahua 5), he whakakapinga poraka kotahi i roto i te 20 meneti e te tangata kotahi, he rokiroki ka taea te whakarārangi
✅ Ātete ki te Huarere me te Waikura, Roa te Ora
Ka ātete ki te -30℃~100℃ pāmahana tino kino, ātete ki te waikura waikawa/kawakawa/tote, he pai mō te rehu makuku/tote i raro i te whenua
Kua paahitia ngā whakamātautau kawenga 50,000-huringa (e whakatauira ana i ngā pānga tīmatanga/whakamutu o te hiki), kāore he pakaru/whakapēhanga
Te Whakataurite i waenga i ngā Raina Kirihou me ngā Raina Rakau mō ngā Pahu Whakarewa Maina (I runga i ngā Whakamātautau Mara Neke Atu i te 10 Tau)
E whakaū ana ngā whakamātautau parae i runga i ngā hiki maina taura kotahi me ngā diameter o te pahu o te 0.8m-6m i roto i te tekau tau, he nui ngā painga o ngā arai kirihou (he kirihou hangai te nuinga) i ngā arai rakau tuku iho, e ai ki ngā whakamārama i raro nei:
I. Ngā Painga Matua o ngā Raina Kirihou
Te Kaha Mīhini Teitei me te Roa o te Ora Ratonga
Ko te kaha pēhanga he 7-10 ngā wā teitei ake i ngā arai rakau, ā, kāore he pakaru, he pakaru koretake rānei o te awaawa taura i te whakamahinga roa;
Kua manatokohia te roa o te ora ratonga e neke atu ana i ngā arai rakau mā te 5 ngā wā, ka tino whakaiti i te auau o te whakakapinga.
Ātete-Wai, Mama, me te Utaina Taputapu Iti
Te mātotoru tata ki te 0.98g/cm³ (he iti iho i ngā papa rakau e mimitihia ana e te wai), tata kore e mimitihia e te wai;
He māmā ake i ngā arai rakau, e karo ana i te pikinga o te ngoikore hurihuri o te pahu me te ngaronga mana urupare o ngā taputapu, ā, ka pai ake te whai huatanga o te mahi.
He Hanganga Tika, he Ngāwari te Tāutanga me te Tiaki Taura Waea Rino
He mea hanga kia tino tika te hanganga, he maeneene ngā awaawa taura, ā, he tika ngā inenga, kia tika ai te tūnga o te taura waea rino i te wā e tāuta ana;
Ka ārai pai i te "ngau taura" me te "peke taura", ā, ka roa ake te ora o te taura waea rino.
II. Ngā Koha o ngā Ara Rakau me te Hiahia kia Whakakorehia
Kāore ngā arai rakau e tutuki i ngā hiahia keri o ēnei rā, nā te mea e herea ana e ō rātou āhuatanga rauemi:
Pānga Nui ki te Ora o te Taura Waea Rino: Ngāwari ki te pakaru, ā, he iti te kaha, me whakakapi pinepine, ā, ka whakararu i te pono o te hiki whānui;
Ngā Hapa Tāutanga e Ārai Ana i ngā Mōrearea Whakahaere: Ka hāngai te ahunga o te kōhao rakau ki te taura waea rino, ka ngāwari ai te papatahi o ngā awaawa kōpiko, ā, ka kore e ōrite te kakahu; ka taea hoki e te tāutanga koretake te arahi i te hē o te tūnga o ngā taura me te pekepeke, ka tūpono ai te haumaru.
III. Whakapai Anō i ngā Raina Kirihou Hangaia (R&D o te Wheketere Mai i te tekau tau 1990)
Hei whakatika i ēnei take, i tīmata tā mātou wheketere i ngā arai kirihou ātete-mīhini i te tīmatanga o te tekau tau atu i 1990, me te whakapai ake i te mahi i runga i ngā arai rakau:
Roa Ake te Ora Ratonga: E 5 ngā wā roa ake te roa o te ora i ngā arai rakau, tae atu ki te 10 tau i ētahi āhuatanga;
Te Kaha ki te Pikau i te Kawenga: Ka taea te pēhanga pa nui ake, me te kore e pakaru, e kore hoki e pakaru taurite ahakoa i raro i ngā kawenga taumaha mō te wā roa;
Ātete Pai ki te Huarere: Ātete ki ngā taiao maroke/māku, he tino pai mō ngā āhuatanga keri kino o raro whenua (haumākū nui, puehu);
Māmā me te Pūmautanga: He iti te mātotoru (<1g/cm³), kāore e mimiti wai, ā, kāore e piki haere te kaha hurihuri o te pahu, te ngaronga rānei o te mana tauhohe;
Tāutanga me te Tiaki Whai Hua: He mea hanga kia tika te rahi me te maeneene o ngā mata, ka whakaiti i te mahi/te wā tāutanga mā te 50% ki ngā raina rakau, me te whakarite kia tika te tūnga o ngā taura me te whakakore i ngā tūponotanga ngau/pekepeke.
Whakamutunga: Kua noho ko ngā arai kirihou (ina koa ko ngā kirihou hangarau) hei whakakapi pai mō ngā arai rakau, he mea whakamahi whānuitia mō te tiaki i te pahu huti maina nā te mea he kaha, he roa te ora, he mama, he ngāwari te tāutanga, ā, he kaha hoki ki te tiaki i te taura waea maitai.
