He aha i tere ake ai te whakangaro a te oneone waikura i ngā tokotoko whenua iti te utu i tō whakaaro

Āheate waikura o te tokotoko whenua kua whakapūmauhiaKi te puta mai i te papa o tētahi kaupapa, ko te pūtake o te take he maha tonu ngā wā ka hoki ki tētahi whakataunga hoko e kitea pinepinetia ana e mātou, e whakatairanga ana i te utu iti rawa i te pai o ngā rauemi. E kitea tonutia ana tēnei tauira i roto i tā mātou wheketere: ka tono te kaimahi kirimana i ngā tokotoko iti rawa te utu mai i tētahi kaiwhakarato iti te utu, ka tāuta ki te oneone kaha me te kore he aratohu mai i a mātou, kātahi ka whakapā mai ki a mātou i muri i ngā tau e rua, e toru rānei, me te pātai he aha rātoukua rahua te pūnaha whenuate whakamātautau ārai.

E whakamārama ana ā mātou miihini ko te paninga konutea i runga i te tokotoko whenua kua whakakikoruatia he mahi hei anode patunga tapu. Ka waikura pai ake, ka tiaki i te matua maitai i raro. Kia pau te paparanga konutea, ka waikura tere te maitai tahanga, ā, ka ngaro te hanganga o te tokotoko me tōna hononga hiko ki te oneone e karapoti ana. I roto i ngā āhuatanga oneone ngawari me te pH tata-kore me te makuku iti, ka roa pea ā mātou tokotoko kua whakakikoruatia wera-tuku mō te 20 ki te 30 tau. I roto ite whakatō oneone waikurangā tono, ka tino hinga taua rārangi wā.

Ka taea e tātou te tohu ki tētahi whakaurunga takutai i te rohe o te Moana-a-Kiwa o Pāhia e whakaatu mārama ana i tēnei. Kei roto i te oneone i te nuinga o te takutai o te UAE me Saudi Arabia he nui ngā taumata o te hauota me te whanariki rewa, me ngā pānui ātete tae noa ki te 200 ohm-henimita. I raro i ēnei āhuatanga, kua kite tātou ka ngaro te tiaki konutea o tētahi tokotoko angiangi kua pania ki te hiko i roto i te 3 ki te 5 tau. Kātahi ka waikura te matua maitai i te tere o te 0.5 ki te 1.0 mirimita ia tau, ka mutu te mahi.te pakaru o te tokotoko whenuai mua noa atu i te mutunga o te oranga o te hanganga e tiakina ana e ia. Ko te kaimahi kirimana i penapena i ētahi tāra mō ia tokotoko, kei te aro atu inaianei ki ngā utu nekehanga, keri, taraiwa anō, me te whakamātautau anō e nui ake ana i te utu hoko taketake.

Kua tuhia e tā mātou tīma hangarau ngā hua ōrite puta noa i te tonga-mā-rāwhiti o Āhia, ā, ka tohaina e mātou ēnei kitenga ki ā mātou kiritaki, arā, ko ngā oneone laterite waikawa me ngā uara pH i waenga i te 3.8 me te 5.0 ka tere ake te whakarewa i ngā paninga konutea. Ko ngā kaupapa i Mareia, Indonesia, me Philippines i tautuhi i ngā tokotoko whakarewa paerewa me te kore e whakaaro ki te waikawa o te oneone, me whakakapi ngā tokotoko i roto i te 5 ki te 8 tau. Ka kite mātou i tēnei tauira e puta tonu ana puta noa i ngā whenua me ngā momo oneone, ā, ko tā mātou whakatau he rite tonu: ko te utu iti rawa te hua o te rahunga tino utu nui ina kore te whakatakotoranga tokotoko e ōrite ki ngā āhuatanga o te papaanga.

He aha te mea e waikura ai te oneone? pH, te ātete, me te hanganga matū

Ehara te waikura oneone i te āhuatanga kotahi e taea te ine. Ka puta mai i te pānga whakakotahi o ngā āhuatanga matū me ngā āhuatanga ā-tinana maha e rerekē ana i runga i te hohonu, te wā, me te wāhi. Ka āwhina mātou i ngā kaihangarau me ngā kaiwhakatakoto whakaaro kia mārama ki ēnei āhuatanga kia taea ai e rātou te whiriwhiri i te mea tika.tokotoko oneone whakakoimō tētahi pae kua whakaritea.

pH oneone me te tere whakarewa konutea

taumata pHe whakahaere ana i te taiao matū e karapoti ana i te tokotoko. Ka whakarewahia te konutea e te oneone waikawa me te pH i raro i te 5.5 mā te whakaeke matū tika, ka puta he tote konutea wairewa e horoia ana, ā, ka whakaatuhia te konganuku hou ki te waikura anō. Ka hangaia e te oneone kawakore me te pH i runga ake i te 9.0 he paparanga konutea waikura e ātete ana ki te waikura, engari ko te noho mai o te warowaihā, te haukini rānei i roto i te oneone kawakore ka taea te whakararu i tēnei parenga. I kitea e mātou ko te oneone tata-kore (pH 6.0 ki te 8.0) te taiao ngawari rawa atu mō ā mātou paninga konutea.

Te Ātete Oneone me te Tere Waikura

Te ātete oneonee ine ana i te kaha o te oneone ki te kawe i te iahiko hiko, ā, e hono ana ki te nui o te makuku me te kukū katote rewa. Ko te ātete iti (i raro i te 1000 ohm-henimita) e tohu ana i te makuku nui me ngā tote rewa, e tere ake ai te waikura o te rakau whenua kua whakapūmautia. Ko te ātete teitei (i runga ake i te 5000 ohm-henimita) e tohu ana i te oneone maroke, onepu, toka rānei e puhoi haere ana te waikura. Ka whakamahia e mātou tePaerewa ASTM G57, e whakaahua ana i te tikanga Wenner e whā-pine ana e mau tonu ana hei paerewa ahumahi mō te ine i te ātete ā-marae, ā, e taunaki ana mātou kia whaihia e ō mātou kiritaki.

Te Whakaekenga o te Hauhāora, te Whanawha, me te Waikawa Waro

Te hanganga matūKa whakaoti i te pikitia. Ka whakaekea tika ngā paninga konutea e ngā katote konutea, ka hangaia he waikura poka e uru ana ki te paparanga konutea i ngā wāhi motuhake, ā, ka tere ake te tae atu ki te pūtake maitai i te waikura mata ōrite. Ka whakaputahia e ngā huakita whakaiti-whāwhā i roto i te oneone anaerobic kua rumakina ki te wai te hauwai whanariki, ka tauhohe ki te konutea hei hanga konutea whanariki, he matū kore-tiaki. Ka whakarewahia e ngā waikawa waro i roto i te oneone nui-peat me te humus te konutea mā te chelation, ā, ka whakamāramahia tēnei e mātou i roto i ā mātou taunakitanga. Ka arotakehia e tā mātou tīma i Shibang ngā raraunga matū oneone mai i ngā pae kiritaki kia ōrite ai tā mātou whakatakotoranga paninga tokotoko ki te riri waikura tuturu. Ka whakakahore mātou ki te whakawhirinaki ki ngā whakaaro kotahi-rahi-e-mō-te-katoa nā te mea e whakaatu ana tā mātou wheako he rerekē ia pae.

Te Tiakitanga o te Uho Rino e te Whakarewatanga Tuku-Hot (me ngā Wāhi e Hinga ai)

Mā te whakapūmau wera-tuku ka hangaia he hononga whakarewa i waenga i te konutea me te maitai mā te tuku i te tokotoko maitai kua oti te whakarite ki roto i te kaukau o te konutea rewa i te pāmahana tata ki te 450 nekehanga Celsius. Ka puta he hanganga paninga maha-paparanga i roto i te tukanga: he paparanga o waho o te konutea parakore, he paparanga konutea-rino waenga, me te papa maitai. Ka whakanuia e mātou tēnei hanganga nā te mea he mea nui mō te ātete ki te waikura: he mārō ake ngā paparanga konutea, ā, he ātete ake ki te waikura i te konutea parakore anake, koia te take e pai ake ai ā mātou tokotoko i ngā momo angiangi kua whakapūmau hiko.

Ngā Paerewa Taumaha Paninga me tā Mātou Tukanga Whakaputa

I tō mātou wheketere, ka whai mātou itokotoko whenua whakarewa wera-tukungā paerewa whakaputa e tuku ana i ngā taumaha paninga o te 550 karamu/m2, neke atu rānei, me ngā matotoru noa o te 70 ki te 80 maikorona. He whakapainga nui tēnei i ngā paninga hiko-whakarewa, e ahu mai ana i te 5 ki te 15 maikorona. Ka kite mātou i tētahi rerekētanga nui i roto ite roa o te oranga o te tokotoko whenua kua whakakikoruatiai waenganui i ēnei tukanga e rua: ko ā mātou tokotoko tuku-wera ka roa te mahi mō te 15 ki te 25 tau i roto i te oneone waikura āhua, ko ngā tokotoko hiko-piupiu i roto i te oneone kotahi ka mutu te mahi i roto i te 3 ki te 7 tau.

Tikanga Anode Patunga Konutea

Ka mahi te tikanga tiaki patunga tapu mā te mahi hikohiko. He nui ake te kaha hiko kino o te konutea i te maitai, nō reira, ina noho ngā konganuku e rua i roto i te electrolyte (oneone mākū), ka waikura te konutea, ā, ka noho tonu te maitai i te tiakitanga katote. Ko tēneipānga anode patunga tapuKa tiakina te maitai ahakoa ngā karawarawa iti, ngā pakaru rānei o te paninga konutea, he painga nui tēnei i ngā paninga ārai-anake pērā i te peita, i te epoxy rānei.

E mārama ana mātou mō ngā ngoikoretanga o te whakapūmau wera-tuku, arā, i ngā taiao tino kino. I roto i te oneone he nui ake te kukū o te hauota i te 500 ppm, te pH i raro i te 4.0, te ātete rānei i raro i te 200 ohm-henimita, ka tere te memeha o te paninga matotoru o te whakapūmau wera. Ka aro pai tā mātou tokotoko whenua whakapūmau matua maitai Q235 ki ngā wero waikura ngawari, engari ka kī pono tonu mātou ki ō mātou kiritaki: ina pana te raraunga oneone ki te awhe tino kaha, ka roa ake te ora o ngā tokotoko parahi, ngā tokotoko kowiri tira rānei. Ko tā mātou whakautu hangarau pono ko te whakataurite i te rauemi tokotoko ki te kaha o te waikura. Kāore mātou e hoko nui rawa i ngā hua whakapūmau i roto i ngā taiao ka pouri rātou.

Te Utu Tuturu o te Rahunga o te Rakau Whenua i te Marae

E mōhio ana mātoute pakaru o te tokotoko whenuaKāore i te maha ngā wā ka puta ngā kōrero matua, engari ka pāngia ngā tahua kaupapa, ngā wātaka, me ngā tuhinga mō te haumaru e ōna pānga. Ina ngaro te whakatakotoranga ārai i te pūnaha whenua, ka tūpono te whare e tiakina ana e ia ki te pikinga o te mōrearea mai i ngā whiunga uira, ngā ia hapa, me te tukunga hiko tūmau. E hiahia ana ngā whakahaere ture i te nuinga o ngā rohe whakahaere ki ngā uara ātete whenua kua tuhia, ā, ki te kore e angitu te whakamātautau, ka puta he whakatikatika whakahau.

E kī mai ana ā mātou kiritaki ko ngā utu tika mō te whakakapi i ngā tokotoko whenua kua waikura ko te mahi keri, te hoko tokotoko hou, te taraiwa, te whakakotahi rānei i ngā taputapu keri, me te whakamātautau anō. I roto i ā mātou wheako ki te tautoko i ngā kiritaki o tāwāhi me ngā tāutanga nui, ko te utu whakakapinga mō ia tokotoko kei waenga i te 5 ki te 15 ngā wā o te utu hoko tokotoko taketake, i runga i te urunga atu ki te papa me ngā āhuatanga o te mata. Me pakaru me te ringihia anō te tokotoko kua tāutahia ki raro i te papa raima, i te mata uku rānei, ā, ka nui ake te utu.

E kitea ana e mātou he nui ake ngā utu ā-kore i ngā utu ā-tika. Tērā pea ka pāngia te pourewa whakawhitiwhiti kōrero e kore e arotau i te whenua kia mutu rā anō te pūnaha i te whakamātautau anō. Ka piki ake ngā pakaru o ngā taputapu nā te ngaohiko tauwhiro i roto i te pokapū raraunga kua ngoikore te whenua. Ka kitea he nui ake ngā hapa taputapu me ngā hapa hiko i roto i te tipu ahumahi kāore i te pai te whenua. Ka roa ake te roa o ēnei whakararuraru mahi, ā, ka nui ake te utu i te whakakapinga tokotoko tinana.

I Saudi Arabia, i mahi tahi mātou me tētahi kaimahi kirimana nāna i tāuta ngā tokotoko hiko-whakarewa ki tētahi pāmu rā i te oneone koraha i te takutai moana, me te kore e kōrero tuatahi ki tā mātou tīma. I roto i ngā tau e whā, kua piki ake te aukati o te pūnaha whenua ki runga ake i te rohe whakatakotoranga nā te kaha o tete waikura o te tokotoko whenua kua whakapūmauhiaI hiahiatia te whakaoho anō i te kapa tāutanga mō te kaupapa whakakapinga, te kawemai i ngā rākau hou, me te whakarite i tētahi kati mō ngā rā 10 i te wā e mahi ana te arai hiko pūngao rā me te kore he parenga katoa. Ko te utu whakakapinga katoa i nui ake i te tahua whenua taketake mā te waru tau. I kī atu mātou ki te kiritaki ka taea te ārai i tēnei putanga mā te aromatawai oneone tika me te whakatakotoranga o tā mātoutokotoko whenua whakakoime te taumaha paninga e tika ana mai i te tīmatanga.

Me pēhea te tautuhi i te tokotoko whenua whakakoi tika mō te oneone waikura

Ka tīmata te whakatakotoranga o ngā tokotoko whenua whakapūmau mō te oneone waikura mā te tirotiro i te wāhi, ā, ka mutu mā te tuhinga hoko e hono ana i te taumaha o te paninga tokotoko ki ngā tawhā oneone kua inehia. E whai ana tā mātou tīma i Shibang i tētahi huarahi hanganga kua whakatikatikaina e mātou mō ngā tau 17 neke atu o te tuku i ā mātou hua whenua ki ngā kaupapa o te ao, ā, ka tohaina whānuitia e mātou ki ā mātou kiritaki.

Aromatawai Oneone me te Whakarōpūtanga Waikura

Hipanga 1: Whakamātautau Oneone.Whakahaerehia he whakamātautau ātete i ngā hohonutanga maha mā te whakamahi i te tikanga Wenner (ASTM G57). Kohia he tauira oneone i te hohonutanga taraiwa tokotoko kua whakaritea hei tātari taiwhanga mō te pH, te pūhaumāota, te whanariki, me te ihirangi waikawa waro. Whakamātauria i ngā āhuatanga o te wā maroke me te wā ua mēnā he tauira ua hauā, he tauira ua ā-wā rānei te wāhi.

Hipanga 2: Te Whakarōpūtanga Waikura.Ka whakarōpūhia e mātou te kaha o te oneone mā te whakamahi i ngā paerewa kua whakatūria.NACE Internationale whakarato ana i ngā aratohu mā SP0169, i te meaIEC 62561e aro ana ki te kōwhiringa wāhanga whenua. Ko te oneone kua whakarōpūtia he tino waikura me whai whakaritenga tokotoko rerekē i te oneone waikura ngawari.

Te Kōwhiri i te Taumaha Paninga me te Diameter o te Rākau

Hipanga 3: Kōwhiringa Taumaha Paninga.Tātaitia te taumaha o te paninga konutea ki te kaha o te waikura. Ka tūtohu mātou:

• Oneone waikura pakupaku(pH 6-8, ātete >3000 ohm-cm): Paninga tuku wera paerewa o te 460 g/m2
• Oneone waikura āhua(pH 5-6, ātete rānei 1000-3000 ohm-cm): Paninga wera matotoru o te 550 g/m2
• Oneone tino waikura(pH <5, ātete rānei <1000 ohm-cm): Whakaarohia te mea whakakikoruatia ki te parahi, ki te kowiri tira rānei

Hipanga 4: Te Diameter me te Roa.Ka tūtohu mātou i tētahi tokotoko matotoru ake nā te mea he nui ake te puna konutea patunga tapu, ka roa ake te ora ratonga. Ko ngā diameter paerewa kei waenga i te 14 mm ki te 20 mm, me te roa mai i te 1.5 mita ki te 3.0 mita. I roto i te oneone tino waikura, ko te piki ake mai i te 14 mm ki te 17.2 mm te diameter ka nui ake te ora ratonga nā te mea ka roa ake te mimiti o te paparanga konutea matotoru.

Hipanga 5: Ngā tuhinga.E hiahia tonu ana mātou ki ngā tiwhikete mira e whakaū ana i te taumaha o te paninga, te kounga o te maitai, me te tutuki i ngā paerewa whakapūmau mō ā mātou hua. E whakarato ana tā mātou wheketere i te ISO 9001:2008 meHe tiwhikete ULngā tuhinga mō ia tukunga ongā tokotoko whenua maitai piauau, e tuku ana i te whai i ngā hua mai i ngā rauemi mata ki te hua kua tāutahia ki ō mātou kiritaki.

Ngā Mahi Tāutanga e Whakaroa ake ai te Roa o te Roopu Whenua

Ka whakamahara mātou ki ō mātou kiritaki ahakoa te tokotoko whenua kua whakapūmautia pai rawa atu, ka ngoikore te mahi mena ka pakaru te paninga konutea i te tāutanga, ka waiho rānei te tokotoko ki roto i ngā āhuatanga e tere ake ai te waikura. Nā ō mātou wheako mara puta noa i ngā whenua maha i ako mai ai mātou ko te kounga o te tāutanga te take nui o te rerekētanga o te roa o te ratonga tokotoko whenua.

Te Hōhonutanga o te Taraiwa me te Tiakitanga o te Tokotoko

Tikanga Taraiwa.Ka tūtohu mātou kia whakamahia he taupoki taraiwa, he parenga pito rānei ina patu ana i tā mātou tokotoko ki te whenua. Mā te patu tika i te pito o te tokotoko ka pakaru te paninga konutea, ka puta te maitai i te tihi o te tokotoko. Mō te oneone toka, ka tūtohu mātou kia keria i mua he kōhao pairati, kaua e akiaki i tā mātou tokotoko mā roto i ngā arai e waru ana i te paparanga konutea. Kei roto i ā mātou tukunga tokotoko ngā pito taraiwa hei āwhina i ngā kaiwhakauru ki te tiaki i te paninga i te wā e taraiwa ana.

Rauemi Whakakī.Ko te oneone e karapoti tonu ana i te tokotoko te mea nui rawa atu te pānga ki te tere o te waikura. I roto i ngā āhuatanga oneone kaha, mā te whakakī anō i te kōhao tokotoko ki tētahi rauemi iti-ātete pērā i te uku bentonite, te raima kawe hiko rānei ka hangaia he takai tiaki huri noa i te tokotoko. Mā tēnei whakakī anō ka whakaitihia te pā o te tokotoko ki te matū kino rawa atu o te oneone taketake, me te pupuri tonu i te hononga hiko e hiahiatia ana mō te mahi whenua. Ko tePaerewa IEEE 80e whakarato ana i ngā aratohu mō te hoahoa pūnaha whenua e uru ana ki ngā whakaaro mō te whakakī anō.

Te Hōhonutanga me te Aronga.Ka tohutohu mātou i ngā kaiwhakauru kia panaia te tokotoko ki te hohonutanga katoa kia noho te tihi o te tokotoko ki te 150 mm i raro i te whenua kua oti. Ka tere ake te waikura o ngā tihi tokotoko e kitea ana i te hononga oneone-hau, ā, ka hangaia he pūtau waikura rerekē i waenga i te makuku me te hāora. Ko te nuinga o te wā, ka pai ake te whakaurunga poutū i ngā koki panaia nā te mea ka whakanohoia te pito tokotoko ki ngā āhuatanga oneone hohonu ake, pumau ake.

Ngā Tikanga Whakakī me te Hononga

Te Parenga Hononga.He ngoikore te hononga i waenga i te tokotoko whenua me te ara iahiko ki raro mēnā ka waiho kia kitea. Ka tūtohu mātou kia tāpirihia he rīpene ārai-waikura, he ringaringa whakaiti-wera rānei ki runga i te hononga miihini hei ārai i te urunga mai o te makuku. I roto i tā mātou wheketere, ka hangaia e mātou he tokotoko me ngā taura whakapiripiri e whakakore ana i te raruraru waikura hononga mā te whakarato i tētahi pūwāhi hononga whakarewa i hangaia e te wheketere.

Āhea te Whakapai Ake: Ngā Huarahi Whakakapi Parahi, te Kowiri tira rānei

Ki tā mātou whakaaro he pai te mahi a ngā tokotoko whenua kua whakakikoruatia mō te nuinga o ngā mahi whenua. I roto i te oneone he iti te kaha o te waikura, ka tukuna e te tokotoko kua whakakikoruatia wera-toia kua tohua tika te mahi pono i te utu iti iho i te utu o ngā momo parahi, kowiri tira rānei. Heoi, he mārama ngā paepae hangarau e pai ake ai te hua mō te wā roa mēnā ka whakapai ake ki tētahi rauemi ātete-waikura.

Ngā Rākau Parahi mō te Oneone Kaha

Ngā tokotoko parahiwhakamahia he paparanga parahi hono-ngota ki runga i te matua maitai kaha-teitei. Ka ātete te paparanga parahi ki te waikura i roto i ngā taiao waikawa me te nui-hauora e tere ai te memeha o ngā paninga konutea. Ko te tokotoko kua whakakikoruatia ki te parahi ka tukuna he 30 ki te 40 tau o te mahi i roto i ngā āhuatanga oneone e whakawhāiti ana i ngā tokotoko piauau ki te 8 ki te 12 tau. Ka mau tonu hoki te ātete whenua iti ake, pumau ake hoki o te paparanga parahi i roto i te wā, he painga tēnei mō ngā whakaurunga hiko tairongo.

Kowiri tira mō ngā taiao tino kino

Ngā tokotoko kowiri tira(ngā taumata 304 me te 316) e whakarato ana i te ātete waikura teitei rawa atu i roto i ngā rauemi tokotoko whenua noa. Ka taea e te maitai kore waikura taumata 316 te tu atu ki ngā kukū konupora e whakangaro ana i te konutea me te parahi, ā, koinei te whiringa pai mō ngā papaaho moana, ngā tipu matū takutai moana, me ngā hanganga moana. E kite ana mātou ko te utu te mea e pai ana: ko te utu o ngā tokotoko kore waikura he 4 ki te 8 ngā wā nui ake i ā mātou mea rite kua whakakikoruatia.

Ka tohutohu mātou ki ō mātou kiritaki kia whakamahi i tētahi anga whakatau māmā: tohua ngā tokotoko whakarewa ina tautokohia e ngā raraunga whakamātautau oneone he roanga mahi e rite ana ki te roanga hoahoa hanganga. Ina whakaatu ngā raraunga oneone i ngā āhuatanga kaha e hiahia ana kia whakakapia te tokotoko i roto i te wātaka kaupapa, ka huri te whakatairite utu ki te parahi whakakikoruatia, ki te kowiri tira rānei. Ka whakaratohia e tā mātou tīma tēnei tātaritanga hei wāhanga o tā mātou tautoko hangarau i mua i te hoko, ā, ka tukuna e mātou ngā kōwhiringa rauemi e toru mai i tā mātou whānuitanga hua iXinchang Shibang.

Pirau, Parahi, Rino Korekore: Whakataurite Taha-ki-Taha

Kei te ripanga i raro nei ngā āhuatanga matua o te mahi me te utu o ngā rauemi matua e toru mō te tokotoko whenua. Ka tūtohu mātou kia whakamahia tēnei hei tīmatanga mō te whiriwhiri rauemi, engari ka tūtohu tonu mātou kia whakaūtia mā te whakamahi i ngā raraunga whakamātautau oneone tuturu mai i te papa o tō kaupapa.

Ngā Pātai Auau mō te Waikura o te Rākau Papa Pirau
