Ahakoa he rawaka te whakamahinga o te rino waro i roto i te maha o ngā kaupapa hanga, i ētahi wā, kāore e taea e te raima te whakarato i te tiaki taiao e ranea ana. He pono rawa tēnei mō ngā taiao moana me ngā taiao e whakamahia ana ngā kai tango hukapapa, ka arahi pea tēnei ki te waikura i puta mai i te hauhā. Mena ka whakamahia ngā rino miro rino kore waikura ki roto i aua taiao, ahakoa he nui te haumitanga tuatahi, ka taea e rātou te whakaroa i te roa o te ora o te hanganga me te whakaiti i ngā hiahia tiaki, ā, ka whakaiti i ngā utu mō te wā roa.
He aha i whakamahia ai te kowiri tirapā rakau?
Ina uru ngā iona pūhaumāota ki roto i te raima whakakaha maitai waro, ā, ka pā ki te maitai waro, ka waikura te rino waro, ā, ka whānui haere ngā hua waikura, ka pakaru, ka tihore te raima. I tēnei wā, me mahi te tiaki.
Ka taea e te rino waro te tu atu ki te 0.4% te ihirangi katote hauota anake, ko te rino kore waikura ia ka taea te tu atu ki te 7% te ihirangi katote hauota. Ka whakapai ake te rino kore waikura i te roa o te mahi o te hanganga, ā, ka whakaiti i ngā utu tiaki me te whakatika.
He aha ngā painga o te kowiri tirapā rakau?
1. He ātete nui ki te waikura o te katote hauota
2. Kāore e whakawhirinaki ki te kawakore teitei o te raima hei tiaki i ngā pae maitai
3. Ka taea te whakaiti i te matotoru o te paparanga tiaki raima
4. Kāore he take ki te whakamahi i te hiri raima pēnei i te silane
5. Ka taea te whakangawari i te whakaranu i te raima kia tutuki ai ngā hiahia o te hoahoa hanganga, me te kore e whai whakaaro ki te tiakitanga o ngā pae rino.
6. Whakapai ake i te pakari o te hanganga
7. Whakaitihia ngā utu tiaki me te whakatikatika
8. Whakaitihia te wā kore mahi me ngā utu tiaki o ia rā
9. Ka taea te whakamahi mō ngā wāhi tino mōrearea
10. Ka taea te hangarua mō te whakahoutanga
Āhea te maitai kore waikurapā rakaume whakamahi?
Ina pāngia te hanganga e ngā katote hauota nui me/ngā taiao ahumahi waikura rānei
Ngā rori me ngā piriti e whakamahi ana i ngā tote whakakore huka
Ina hiahiatia (e hiahiatia ana rānei) kia kore e aukume te rino rino
Kei hea te maitai kore waikura e tika anapā rakaukia whakamahia?
Me whai whakaaro ki te rino kowiri tira i roto i ngā āhuatanga e whai ake nei
1. Taiao waikura
Ngā punga mō ngā piriti, ngā tauranga, ngā arawhata, ngā pareparenga wai, ngā pakitara moana, ngā pou rama, ngā reera rānei, ngā piriti huarahi nui, ngā rori, ngā arawhata piki, ngā arawhata piki, ngā papa waka, me ētahi atu i roto i te wai moana, inā koa i ngā āhuarangi wera
2. Te whare tango tote wai moana
3. Ngā wāhi tukatuka paru
4. E hiahiatia ana ngā hanganga whare roa te ora pērā i te whakaora i ngā whare tawhito me ngā whare rokiroki mō ngā para karihi.
5. Ngā wāhi e pāngia ana e te rū whenua, nā te mea ka hinga pea ngā hanganga raima whakapakari i te wā o te rū whenua nā te waikura
6. Ngā ara me ngā kauhanga o raro whenua
7. Ngā wāhi kāore e taea te tirotiro, te tiaki rānei mō te whakatikatika
Me pēhea te whakamahi i te kowiri tirapā rakau?
I ngā whenua ke, ko te nuinga o te wā ka hangaia te rino kowiri tira kia rite ki te paerewa o Peretānia BS6744-2001 me te paerewa o Amerika ASTM A 955/A955M-03b. He paerewa ā-motu anō hoki ā Wīwī, Itari, Tiamana, Tenemāka, me Pinirana.
I Haina, ko te paerewa mō te rino kowiri tira ko YB/T 4362-2014 "He rino kowiri tira mō te raima whakapakari".
Ko te whānui o te rino kowiri tira he 3-50 mirimita.
Ko ngā momo e wātea ana ko te maitai kore waikura takirua 2101, 2304, 2205, 2507, te maitai kore waikura austenitic 304, 316, 316LN, 25-6Mo, me ētahi atu.
