I te hauwhā whakamutunga, i tukuna mai e tetahi kaihoko he tuhinga a tetahi kaiwhakataetae ki ahauwhakamātautau rehu tote tokotoko whenuapūrongo, ā, kotahi te pātai i pātaihia: "He pai ngā hāora 96?" I miharo ia ki taku whakautu: ko te tau te rārangi iti rawa o te whārangi. He mahi whakahaere rūma te ASTM B117 — e kī ana ki te taiwhanga me pēhea te whakahaere i te kohu, ā, e whakakahore ana ki te kī atu ki a koe he aha te tikanga o te hua mō te roa o te mahi. Ko te mea e whakatau ana mēnā ka tiakina e taua pūrongo tō kaupapa ko ngā mea katoa e pā ana ki te tatau hāora: ko ngā tawhā rūma e rima, te whakarite tauira, te tikanga aromatawai, te tatau tārua, me te whakamanatanga a te taiwhanga. Ka whakaae, ka whakahē rānei ahau i ngā taunakitanga waikura a ngā kaiwhakarato i ia marama, ā, ko tēnei aratohu te raupapa pānui tika e whakamahia ana e au — me ngā tau e puta ana i runga i tētahi pūrongo pono, te taunakitanga kua tuhia kāore ngā hāora rehu tote e honoa ki ngā tau, me tētahi tirotiro haki whero tauwhitiwhiti ka taea e koe te whakahaere i runga i tētahi PDF ka tukuna atu e te kaiwhakarato ki a koe.
TL;DR — Pānuihia te Pūrongo i roto i tēnei Raupapa
- Ko te taiao whakamātautau anake te mea e tautuhia ana e te ASTM B117, ehara i te mea ka eke/ka hinga: e kī ana te paerewa "kāore e tohu i te momo tauira whakamātautau, i ngā wā whakaatu rānei... me te whakamāramatanga hoki mō ngā hua" — nō reira, kāore i oti te pūrongo kāore he paearu whakaae a te kaihoko.
- E kī ana tētahi pūrongo pono e rima ngā tawhā o te rūma: te otinga NaCl 5%, 35°C ± 2°C, te pH 6.5–7.2, te tere taunga kohu o te 1.0–2.0 mL/h mō ia 80 cm², me ngā tauira i te 15–30° mai i te poutū; ki te ngaro te tawhā, kāore e taea te tārua i te oma.
- Kāore ngā hāora rehu tote e huri hei tau ratonga: e whakaatu ana tētahi huinga raraunga parae kua tuhia he tauira 200-hāora te roa mō te 20 tau i Mumbai, ā, i rahua te tauira 144-hāora i roto i te 2 tau i New Delhi — he hononga Pearson o te +0.66 noa iho ahakoa i waenga i ngā wāhanga whakarewa rite.
- Mō te tokotoko oneone parahi kua herea, ka puta noa te waikura whero i te maitai kua kitea, nō reira ko te wāhi e puta ai te waikura — ngā pito kua tapahia, ngā miro, ngā rārangi tuhituhi — e whakaatu ana i te wāhi i pakaru ai te paparanga parahi, koia te take he mea nui ake ngā tuhipoka whakarite tauira i ngā hāora matua.
- Ka whiwhi tā mātou taputapu tirotiro 8-ira i ngā pūrongo a te kaiwhakarato i roto i ngā meneti e rua; mēnā he hapa ngā tawhā rūma, tikanga aromatawai, whakamanatanga taiwhanga rānei, ka pātaihia i mua i te whakaaetanga.
He aha te ASTM B117 Tuturu — he Mahi ā-Rūma, ehara i te Whakatau
Ko te mea tuatahi ka tirohia e au i tetahiASTM B117 tokotoko whenuaKo te pūrongo e whakaatu ana mēnā e mārama ana te kaiwhakarato ki tā rātou e pupuri ana. Ko te taitara katoa o B117 ko te Standard Practice for Operating Salt Spray (Fog) Apparatus, ā, ko te kupu matua ko te "whakahaere".Ko te whakarāpopototanga a ASTM International mō te B117-19e kī ana i roto i te Wāhanga 1.2 kāore te mahi "e whakarite ana i te momo tauira whakamātautau, i ngā wā whakaaturanga rānei hei whakamahi mō tētahi hua motuhake, kāore hoki i te whakamāramatanga hei hoatu ki ngā hua." Kei roto i te Wāhanga 3.2 te kōrero: "Kāore i te maha ngā wā i honoa ai te matapae o te mahi i roto i ngā taiao tūturu ki ngā hua rehu tote ina whakamahia hei raraunga tūkotahi."Nā te mea ko te kohu anake te mea e tautuhia ana e te paerewa, ā, e kore e tautuhia te rārangi mutunga, ehara i te hua whakamātautau te pūrongo e whakaatu ana i ngā hāora me te kore he paearu whakaae a te kaihoko — engari he pūrongo huarere nō roto i te pouaka.
Ehara tēnei i te pānui taha noa iho, ā, ehara ko au anake tēnei e kōrero ana i tēnei.Te pānui hangarau a Sherwin-Williams mō ngā herenga o te B117E whakahua ana i tētahi pepa SSPC o te tau 1995 e whakatau ana ko te tikanga he "huarahi tere engari kāore e pono mō te matapae i te whanonga paninga," me te kī kāore te mahi i hangaia hei whakataurite i ngā tauira e whakahaerehia ana i roto i ngā rūma rerekē i raro i ngā āhuatanga ōrite. Heoi, kei te kite tonu ahau i ngā RFQ e kī ana ko "te whakamātautau rehu tote e hiahiatia ana," e hoatu ana ki te kaiwhakarato he haki kau: ka whiriwhiria e rātou ngā hāora, ka whiriwhiria e rātou te aromatawai, ka whakapuakina e rātou te whakaaetanga. Kāore he utu mō te whakatikatika, ā, ka tuhia e au ki roto i ia RFQ ka arotakehia e au: ka whakatakoto te kaihoko i te rārangi whakaae, ā, ka oma te taiwhanga ki reira.
Ngā Tawhā Rūma e Rima Me Puta ki te Whārangi
Ina whakatuwhera ahau i tētahipūrongo whakamātautau waikura, ka haere tika atu ahau ki te poraka whakamātautau-āhuatanga, nā te mea ka taea anake te tārua i te oma kohu mēnā e rima ngā tau kua tuhia. E ai ki ngā tawhā whakahaere i tuhia eWhakarāpopototanga o te tikanga ASTM B117 a Cotec Labs, he rehu tote kūpapa e pupuri ana i te otinga konutai pūhaumāota 5% i te pH 6.5–7.2, he pāmahana rūma 35°C ± 2°C, he haumākū tata ki te 95% ± 5%, me te tere taunga kohu 1.0–2.0 mL ia hāora mō ia 80 cm² o te wāhi kohikohinga, me ngā tauira e anga ana ki te 15–30° mai i te poutū. Mena he roa me te whakaahua anake e whakaatuhia ana e te pūrongo, kāore e taea e au te kī he oma ōrite mai i te whakamaroke makawe e tohu ana ki te peere.
| Tawhā | Uara tutuki | Ngā mea ka tohua e au mēnā kei te ngaro |
|---|---|---|
| Te kukū o te tote | 5% NaCl mā te papatipu (50 g/L akomanga) | Ka huri te kukū hē i te tere o te waikura; ka kore e taea te whakataurite i ngā hua |
| pH o te otinga | 6.5–7.2 i te wā i whakakāhia ki te 35°C | He whakamātautau rerekē te kohu waikawa (pH < 6.5) he whakamātautau uaua ake, e kiia ana he koretake. |
| Te pāmahana o te rūma | 35°C ± 2°C | Ka tere ake te whakaeke i te pāmahana teitei; ka nui haere te "mahi" i runga i te utu a te kaihoko |
| Te tere o te taunga o te kohu | 1.0–2.0 mL/h mō ia 80 cm² | Ko te kohu iti te huarahi māmā ki te whakaari i ngā haora roa |
| Te whakatakotoranga o te tauira | 15–30° mai i te poutū, kāore he pa atu, kāore he maturuturunga iho | Ka tere te waikura o ngā tauira e takoto papatahi ana, e pā ana rānei, — ka roa rānei te wā e waikura ai — ki te mea kua āraia. |
Nā te mea ko ia o ēnei tawhā e rima ka neke i te tere o te waikura, kāore e taea e tētahi taiwhanga tuarua te tārua i tētahi pūrongo e kore e tāpirihia tētahi o aua tawhā — ā, kāore e taea te manatoko i tētahi hua kāore e taea te tārua.I roto i te Wāhanga 3.3, e whakatūpato ana a ASTM ka puta te rerekētanga i waenga i ngā rūma kohu rerekē ahakoa i raro i ngā āhuatanga ōrite, koia te take e hiahiatia ai he tāruarua mō te wāhanga kotahi. E toru ngā tauira mō ia oma i taku papa; kotahi te tauira kua orohia i tangohia i te haora 96 e kōrero ana mō te whakaahua, ehara i te hanga.
Ehara ngā Hāora i te Tau — Te Pānui Pono i te Rārangi Roanga
Ko te hē nui rawa atu i roto i te tohu kaiwhakarato ko te huri i ngā hāora rehu tote ki ngā tau ratonga. Kāore he tauwehenga hurihanga, ā, i roto i taku pānui i ngā raraunga ka kino haere ina titiro matatau koe. He rangahau hononga-marae i whakaputaina eTe wāhanga rangahau a te Rōpū PrestoI whaihia e au ngā wāhanga ahumahi e whā mai i te rūma ki te tāutanga, ā, i kitea tēnei: ko te huihuinga pūwero e eke ana ki te 216 hāora i roto i te kohu i whakaatu i te waikura tuatahi i te 5 tau i te takutai moana o Chennai; ko te pūtu punga whakarewa wera e eke ana ki te 200 hāora i roa mō te 20 tau i Mumbai; ā, ko te whāriki maitai ngawari e whakahaere ana i te 144 hāora anake i roa tonu mō te 2 tau i roto i te hau poke o New Delhi. I pānuihia e au taua ripanga i te huarahi e tika ana mō ia kaihoko: 200 hāora i hokona mō te rua tekau tau i tētahi tāone, ko te 216 hāora i hokona mō te rima i tētahi atu. Ko te tauwehenga Pearson puta noa i ngā tauira whakarewa i puta i te +0.66 — he tohu whakatauranga whai hua, kāore i tata ki te matapae ora — ā, i heke ki te −0.16 i te wā i tāpirihia ai he wāhanga peita.
| Tauira | Ngā hua o te ASTM B117 | Te waikura tuatahi o te mara | Taiao mara |
|---|---|---|---|
| Huinga kōpeke (kua pania ki te MoS₂) | 216 h ki te waikura whero nui | 5 tau | Te takutai moana o Chennai, 25–35°C, 65–85% RH |
| Pūtu punga whakarewa wera-toia | 200 h ki te waikura mā nui | 20 tau | Mumbai, 25–33°C, 80–90% RH |
| Ārai maitai ngawari pania paura | 144 h ki te waikura whero nui | 2 tau | Niu Tirī, teitei te parahanga PM2.5/PM10 |
| Papa peita pango Matt | Kua hipa te 432 h | 5 tau (te pakarukaru) | Te tāone o Pune, 40–65% RH |
Kua roa te umanga e kī ana i tēnei mea.Te maheni CoatingsTech a te American Coatings Associatione kī ana i te B117 he "paerewa tūāpapa" 86-tau te pakeke mō te whakatauranga whakatairite - me te whakatūpato kei te whakamahi hē ngā kaihoko e "honohono ana i ngā hāora ki te rahunga o te rehu tote ki te roa o te hua", nā te mea ka tāpirihia e te pānga tūturu te UV, te huringa mākū-maroke, ngā huringa pāmahana, me ngā poke e kore e puta mai i te kohu tonu. I roto i ngā pūrongo e whiti ana i taku tēpu, ka oma ngā matapihi pānga mai i te 24 hāora ki te neke atu i te 1,500 hāora i runga i te whakatakotoranga - e whakaatu ana ki a koe te tere o te tau.Nā te ātete oneone, ngā hononga konukōre, me ngā ia rere kē te take o te waikura o raro whenua, kaua ko te kohu pūhaumāota, kāore rawa he kupu a te mētara rūma 500-hāora mō ngā tau 30–50 e hiahiatia ana e koe mai i te hiko whenua.
Te Whakarite Tauira: Te Wāhi e Huna ai te Tinana e ngā Pūrongo Ngoikore
Mō te tokotoko parahi kua herea, he tino atawhai ngā tātaritanga waikura ki te kaihoko — e kī ana ahau i tēnā mai i ngā tau maha o te pānui i ngā tauira kua rahua.Nā te mea ko te parahi te konganuku rangatira o tēnei takirua, ka puta noa te waikura whero i ngā wāhi e kitea ana te maitai — nō reira ko te mahere waikura i runga i tētahi tauira kua whakamatautauria he hihi-X tika e whakaatu ana i te wāhi i pakaru ai, i pūwerohia ai, i tihorea rānei te paparanga parahi.Koia ahau i whakaaro ai ko ngā tuhipoka whakarite te paraka tātaritanga tino nui rawa atu o te pūrongo katoa. I whakamatautauria te tokotoko i tōna āhua o nāianei, me ngā pito tapahi e kitea ana? I hiritia ngā miro me te pito taraiwa ki te ware pi, ki te rīpene rānei? I tapahia he kaituhi mā roto i te koti ki te pūtake? Ka rerekē ia kōwhiringa i ngā mea e whakaatu ana i ngā hāora.
Anei taku pānui i ngā whakaritenga e toru e kitea pinepine ana e au. Mā te tokotoko tapahi me ngā pito e kitea ana ka whakamātautau i te āhuatanga kino rawa atu ka puta mai i tō kaiwhakauru i ia tapahi mara - e tika ana kia puta te waikura whero wawe i ngā pito, ā, kāore e whakakore i te whai mana mena ka noho ma te mata porotaka. Mā te tokotoko he pito hiri me ngā miro ka whakamātautau i te koti tonu; ko te waikura whero i runga i te oko inaianei he tohu kei roto he kōhao iti, he porosity rānei i roto i te parahi whakakikoruatia hiko, he rahunga tukanga tūturu tēnei. Ā, ko te tauira kua tohua kua whakatauria i raro i te ISO 10289 - e kī ana te whakamārama a Cotec Labs ka tukuna ngā hua hei tau Rp mō te tiaki waikura whero me te tau A mō te āhua - ka whakamātautau i te ngoki o raro o te kiriata, e kī ana ki a koe mena ka huri te karawarawa i te wā e mahi ana hei paru, hei patunga hanganga rānei. Ko tā mātou ake whakatakotoranga hua e hiahia ana kia tino haere tonu te whakakikorua parahi "me te kore he kapiti, he kōhao, he poka," me te piko 90° i te radius 100 mm me te kore he whati - nā te mea me ora te koti i te rūma me te hama taraiwa.
Whakahaerehia tētahi Pūrongo Kaiwhakarato mā tēnei Tirotiro 8-Pūwāhi
Koinei tonu te mata e whakamahia ana e au i mua i temanatoko kounga o te tokotoko whenuaka tae atu te kōnae ki ā mātou kiritaki. Tīkina te mea kei roto i te pūrongo kei mua i a koe — ka tātaihia e te kaitātari te mea e ai ki taku.
Pūrongo Rehu Tote Kaitirotiro Haki Whero
Ko tāku e tū ai tō mātou ingoa hei utu mō te whakaahua o te rūma
Ka whiwhi te rehu tote i tōna tūranga i roto i taku kōnae whakaae a te kaiwhakarato hei tirotiro whakatairite, ehara i te mea hei turanga. Ko te turanga te mea ka taea e au te ine i ia rā whakaputa i tō mātou wheketere i Xinchang. Mō tā mātoungā tokotoko whenua kua pania ki te parahi, ka tīmata te tautohe waikura me te koti whakakikoruatia hiko tonu o te iti rawa 0.254 mm i te ≥99.95% parakore parahi i runga i te matua maitai waro-iti — te akomanga matotoru o tā mātoutokotoko whenua pania parahi 0.254 mmKa hangaia te rārangi huri noa. Ka maherehia te matotoru mā te ine maikoromita i runga i ngā wahi i tauirahia mai i ia puranga, ka puritia te tika i roto i te 1 mm ia mita, ko te kaha kume i te ≥580 N/mm², ā, me ora ia tokotoko i te piko 90° i te radius 100 mm me te kore he whati parahi, he kino rānei te hononga — ko te whakamātautau e hopu ana i ngā hapa o te koti ka kitea e te rūma kohu kua roa rawa.
Puta noa i te katoangā tokotoko parahite whānuitanga — 14.2–25 mm te whānui, 1.2–3.0 m te roa, 50,000 ngā wahi ia marama — e kapi ana ngā rekoata puranga i te matotoru o te paparanga parahi, te piri, ngā hua piko, me te haere tonu o te whakakikorua, me te katoakāwai tokotoko whenuaKei te tukuna mai me ngā tuhinga pūnaha ISO 9001 kei muri. Ina tono mai tētahi kiritaki mō ngā taunakitanga rehu tote i runga, ka mihi atu ahau — engari ka whakahua pono ahau: he raraunga whakatairite mai i tētahi oma kua tautuhia, me te inenga puranga e tohu ana i te oranga hoahoa 50-tau i raro i te whenua. Mena he takutai moana tō papaanga, he kaha rānei ki te matū, pātai mai ki a mātou mō te ara whakamātautau-hurihuri; he pai ake ki a mātou te whakahaere i te whakamātautau uaua ake i te mātakitaki i a koe e whakaae ana ki te mea ngāwari ake.
Ngā Pātai Auau
E hia ngā hāora e tika ana kia rehuhia he tote ki te whenua, kia pā ki te tokotoko whenua parahi?
Kāore he tohu paahitanga whānui, nā te mea kāore he tohu i whakatakotoria e te ASTM B117 — ko te roa o te whakaaturanga me ngā paearu whakaae kei roto i ngā whakaritenga a te kaihoko. I roto i te mahi, e kite ana ahau i te 48–96 hāora e tonoa ana mō te tirotiro ahumahi whānui me ngā rau hāora e hiahia ana ngā kaihoko ki tētahi kēti whakatairite pakari ake. Ko te huarahi pono ko te whakatika i te paearu tuatahi — hei tauira, kāore he waikura whero i runga i te mata porotaka i te 96 hāora me ngā pito hiri — kātahi ka pupuri i ia kaiwhakarato ki te oma ōrite. Ko ngā hāora anake ka whakarōpū i ngā kaiwhakarato; kāore rātou e whakamana i ngā tau.
E matapaetia ana e te hua ASTM B117 te roa o te ora o te tokotoko i raro i te whenua?
Kāo, ā, ko te paerewa tonu te kī: E kī ana te Wāhanga 3.2 kāore i te maha ngā wā ka honoa te matapae o te mahi i roto i ngā taiao tūturu ki ngā hua rehu tote e whakamahia ana hei raraunga takitahi. Ko ngā irahiko tanumia e anga atu ana ki te ātete oneone, te hononga konukōre, ngā pikinga makuku, me ngā ia rere kē — kāore tētahi o ēnei e puta mai i te kohu pūhaumāota 35°C. E tautoko ana ngā raraunga mara i te whakatūpato: e whakaatu ana ngā kēhi kua tuhia he 200 hāora rūma e rite ana ki te 20 tau mara i tētahi tāone, me te 216 hāora ki te 5 tau noa iho i tētahi atu. Ko te oranga o raro whenua e tautohetia ana mai i te matotoru o te paparanga parahi, te haere tonu, me ngā āhuatanga oneone, ehara i te hāora kohu.
He aha te rerekētanga i waenga i te ASTM B117 me te ISO 9227 mō ngā tokotoko whenua?
He māhanga rāua mō te mahi: e rua e tohu ana i te kohu NaCl 5% kūpapa i te 35°C me te pH 6.5–7.2, ā, ko te pūrongo i tuhia ki tētahi he mea ngāwari te pānui i te nuinga o te wā ki tētahi atu. Ko te ASTM B117 te mea nui rawa atu mō ngā whakaritenga o Amerika Te Raki; ko te ISO 9227 te mea nui rawa atu mō ngā whakaritenga o Ūropi me te ao whānui, ā, ko te ISO 10289 te reo whakatauranga Rp/A mō ngā hua. Ko tāku e rapu nei he pūrongo e whakaingoa ana i tētahi paerewa, e whai katoa ana i taua paerewa, ā, e kī ana i te tikanga aromatawai — he haki whero te "whakamātautauria ia rārangi ASTM/ISO" kāhore he tawhā, ehara i te mea he takahi ture.
E ai ki te pūrongo a te kaiwhakarato "kāore he waikura whero i te 96 hāora." He aha te mea kua whakamātauhia e tēnā?
Ko te mea anake i taea e te whakaritenga te whakaatu. Mena i hiritia ngā pito me ngā miro kua tapahia, e whakaatu ana i te pumau tonu o te koti ki aua tauira mō te 96 hāora — he hua tūturu engari he iti noa iho, nā te mea he mata ahumahi māmā te 96 hāora. Mena i kitea ngā pito, me tumanako ka waikura te pito ahakoa i runga i ngā tokotoko pai, ā, he mea whakapae te ngaro. Ahakoa pēhea, he whakataurite te kereme: ka taea e koe te whakarite i tēnei kaiwhakarato ki tētahi atu i roto i te oma kotahi. Ko te mea kāore i whakaaturia ko te roa o te ratonga i raro i te whenua, te ōritetanga o te puranga-ki-te-puranga, te mahi rānei i roto i tō oneone — me tuhi he rekoata matotoru, ā, mō ngā wāhi uaua, he whakamātautau huringa.
Me tono rānei ahau kia whakamātauria te rehu tote ki ia puranga whakaputa?
Kāore au e pena — ā, kei te whakahaere ahau i tētahi wheketere. He puhoi te oma o ngā rūma, ā, ka tāpirihia he wiki ki te whakamātautau kohu mō ia puranga me te kore e tāpiri i te whakapumautanga tika, nā te mea kei te whakatūpato te wāhanga rerekētanga o B117 ahakoa ngā rūma ōrite te ingoa, kāore e ōrite. Ko te taunakitanga mō ia puranga e hopu ana i te rerekētanga whakaputa tūturu he tere ake, he tika ake hoki: te mahere maikoromita o te matotoru o te parahi, te whakamātautau piri me te piko i te radius 100 mm, me te tirotiro haere tonu o te tirohanga. Puritia te rehu tote mō te tohu me te whakamana anō i ia wā — i ia tau, i muri rānei i tētahi huringa tukanga — ā, waiho mā te inenga o ia rā e tiaki ngā puranga i waenganui.
He aha te whakamanatanga e tika ana kia whiwhi te taiwhanga whakamātautau?
Rapua te whakamanatanga ISO/IEC 17025 me te rehu tote i roto i te whānuitanga kua whakaputaina e te taiwhanga — i Haina ko te tikanga he CNAS-kua whakamanahia, ā, i te ao katoa ko tētahi rōpū hainatanga ILAC-. Kātahi ka mahi i te manatoko e rua meneti te roa, ki taku whakaaro ko te nuinga o ngā kaihoko ka pekehia: whakapā atu ki te taiwhanga me te nama pūrongo me te whakaū i tukuna taua tuhinga mō taua whakaahuatanga tauira. He nui ake te uara o te nama pūrongo ka taea te manatoko mai i tētahi taiwhanga whai mana i tētahi PDF ataahua, ā, mā tētahi kaiwhakarato e whakapono ana ki ā rātou whakamātautau ka āwhina i a koe ki te tirotiro.
He rawaka te pūrongo B117 mō tētahi teihana hiko i te takutai moana, mō tētahi wāhi hanga hinu rānei?
Kāore i te tū motuhake. Ka tāpirihia e ngā āhuarangi takutai me ngā āhuarangi ahumahi te huringa mākū-maroke, te UV, me te matū poke e kore e pā ki te kohu tonu, koia te take i tūtohu ai te arotake a te American Coatings Association kia whakanuia te rehu tote kūpapa me ngā tikanga huringa - ngā momo ASTM G85, SWAAT, te prohesion rānei - me te ISO 12944-9 mō te whakaaturanga āhuarangi. Mō te wāhanga kua tanumia, honoa te whakamātautau āhuarangi me ngā raraunga ātete oneone me te tuhinga matotoru o te paparanga parahi o te tokotoko. Mena kei roto tō wāhi i te hau tote o te takutai, kōrero mai ki a mātou te taiao i roto i te RFQ, ā, ka tūtohu mātou i te huarahi whakamātautau uaua atu ki a koe.
Kei te arotakehia e koe te kōnae waikura a te kaiwhakarato i tēnei wā tonu?
Tukuna mai te pūrongo — ka whakahaerehia e au te mata 8-ira kotahi ki runga, ka kōrero atu ki a koe i roto i te kotahi rā mahi he aha te mea e whakamātauhia ana, he aha te mea e huna ana, me te aha te mea hei tono atu i muri mai. Mena kei te hiahia koe ki ngā tokotoko me te matotoru taumata-puranga me ngā tuhinga piko i muri i ngā raraunga rūma, kua rite tā mātou raina 50,000-wahi ia marama i Xinchang.Tīmatahia te kōrero i runga i tā mātou whārangi whakapā →
Ka āwhina ahau i ngā kaihoko o tāwāhi ki te kimi hua whenua me te tiaki uira mai i tā mātou wheketere 17-tau te roa — kei roto ko te tirotiro kounga, te whakahaere ratonga, me ngā tuhinga kaweake katoa. Ka puta mai ngā pūrongo whakamātautau a ngā kaiwhakarato i taku tēpu i ia marama; koinei te aratohu e pānuihia ana e au.
