Ngā Painga me ngā Tūponotanga o ngā Matū Formalin
Ko te Formalin he wairewa kei roto te formaldehyde i roto i te wai, tata ki te 37% te formaldehyde kei roto, he iti noa te methanol i tāpirihia hei ārai i te polymerization. I roto i te hapori, ko te kupu "formalin" e whakamahia ana hei tohu i tētahi mea tiaki mō ngā tūpāpaku, i tētahi wai rānei he kakara kaha. I tētahi atu taha, he mea nui anō hoki te formalin i roto i ngā mara ahumahi me ngā mara taiwhanga nā ōna āhuatanga whai hua ki te patu i ngā moroiti me tōna kaha ki te "tiaki" i ngā kiko koiora. Heoi, i muri i ēnei painga, he nui ngā tūponotanga o te formalin mēnā ka whakamahia hētia, inā koa mēnā ka whakamahia hētia hei mea tiaki kai. Ka matapakihia e tēnei tuhinga ngā painga ture me ngā painga whakahaere o te formalin, tae atu ki ngā tūponotanga hauora me ngā pānga pāpori o tōna whakamahinga hē.
He aha te Formalin, ā, he aha i whakamahia whānuitia ai?
I roto i te matū, he matū waro māmā noa iho te formaldehyde (CH₂O) e tino tauhohe ana. Ina rewa ki te wai, ka hangaia he formalin e te formaldehyde. Nā tēnei āhua tauhohe te formalin e whai hua ai hei tiaki: ka taea e ia te "here" i ngā pūmua me ngā hanganga pūtau, ka pumau ake ngā kiko, ka ārai hoki i te tipu o ngā moroiti. Hei tāpiri, he iti te utu o te formalin, he ngāwari te wātea i ngā wāhi ahumahi, ā, he tere te mahi. Nā tēnei huinga ka whakamahia whānuitia, engari he ngāwari hoki ki te whakamahi hē.
Ngā Hua o te Formalin i roto i te Ahumahi me te Hauora
Ahakoa e hono pinepine ana tōna ingoa ki ngā mea kino, he maha ngā painga nui o te formalin ina whakamahia kia rite ki ngā ture haumaru me te whakamahinga i whakaritea.
1. Kaiwhakaora mō ngā Tauira Koiora me ngā Kaupapa Hauora
Ko tētahi o ngā whakamahinga rongonui o te formalin ko te tiaki i ngā kiko koiora i roto i ngā taiwhanga, i ngā hōhipera, me ngā whare mātauranga. I roto i te pathology anatomical, ka whakamahia te formalin hei whakatika i ngā kiko (hei whakamutu i te tukanga pirau) i mua i te tirotiro anō. Mā te whakatika tika, ka tiakina ngā hanganga pūtau me te kiko, ka taea ai te tautuhi tika ake i te mate.
I roto i ngā whare wānanga, ka whakamahia hoki te formalin hei tiaki i ngā tauira okana, kararehe rānei mō ngā whakamātautau taiwhanga. Ki te kore he matū tiaki, ka tere te pirau o ngā tauira, ā, ka tūpono pea te poke.
2. Ngā patu huakita me ngā rongoā ārai huakita (Limited)
Ka taea e te formalin te mahi hei patu huakita nā te mea ka taea e ia te patu i ngā huakita, ngā harore, me ētahi huaketo. Heoi, kua whakawhāitihia tōna whakamahinga hei patu huakita i tēnei wā nā ōna āhuatanga whakapataritari me te paitini, me te wātea mai hoki o ētahi atu huarahi haumaru ake. Heoi, i roto i ētahi wāhi ahumahi, i ētahi whare motuhake rānei, ka whakamahia tonutia te formalin i raro i ngā tikanga haumaru tino pakari.
3. Ngā Rauemi Mata mō te Ahumahi Resin me ngā Rauemi
I roto i te ahumahi, he rauemi mata nui te formaldehyde mō te hanga i ngā momo kapia, pērā i te urea-formaldehyde me te phenol-formaldehyde. Ka whakamahia ēnei kapia ki:
– He piripiri mō te papa rakau, te papa matūriki, me te MDF (papa muka matotoru-waenga)
– Ētahi paninga me ngā peita
– He rauemi kakahu ārai-wrinkle
– Ngā wāhanga motuka me ētahi hua kirihou
Nō reira, he mahi nui tā te formalin i roto i te mekameka tuku taonga, inā koa i roto i ngā ahumahi rauemi hanga me ngā taonga whare.
4. Te Whakahaere Kounga me te Tukanga Whakaputa
I roto i ētahi tukanga whakaputa, ka taea te whakamahi i te formaldehyde hei matū tauhohenga hei whakaputa i ētahi matū whakaputa. Ko te tikanga o tēnei whakamahinga ka puta i roto i ngā tipu matū, ā, ka mahia i roto i ngā pūnaha kati i raro i te tirotiro tino kaha. I roto i tēnei horopaki, ko ngā painga ko te whai huatanga o te whakaputa me te kounga hua pumau.
Ngā Tūponotanga o te Formalin mō te Hauora
Ko ngā tūponotanga o te formaldehyde e puta mai ana i ōna āhuatanga paitini, whakapataritari, me te kaha ki te whakaputa mate pukupuku. Ka puta ēnei pānga mā te manawa, te pā ki te kiri, te horomia rānei.
1. Te riri o te manawa me te kanohi
Ka taea e te pānga ki ngā kohu formaldehyde te whakapouri i ngā kanohi, te wai o ngā kanohi, te wera o te ihu me te korokoro, te maremare, me te poto o te manawa. Mō te hunga tairongo, te hunga mate huango rānei, ka taea e te pānga ki te formaldehyde te whakararu i ngā tohu me te whakaoho i te whakaeke.
I ngā wāhi kati me te kore e pai te hauhautanga, ka taea e te kohu formaldehyde te kohikohi ka puta ai ngā mate kino atu pērā i te whanoke, te whakapairuaki, me te ngoikore.
2. Te riri me te kino o te kiri
Ka taea e te pānga tika ki te formalin te whakararuraru, te whero, te wera, tae atu ki te mate kiri pā. Mēnā ka pāngia tonutia te kiri, ka nui ake te aro me te ngāwari o te mate pāwera. Me mau ngā kaimahi taiwhanga, ngā kaimahi ahumahi rānei e pā pinepine ana ki te formalin i ngā taputapu tiaki tinana pērā i ngā karapu ātete matū me ngā tiaki kanohi.
3. Ka paitini mēnā ka horomia
Ko te mōrearea tino kino, ā, e kitea pinepinetia ana, ko te urunga o te formaldehyde ki te tinana mā te kai, mā te inu rānei. Ehara te formalin i te tāpiri kai, ā, kaua e whakamahia hei tiaki kai. Mēnā ka kainga, ka pāngia e te formaldehyde:
– Mamae puku, whakapairuaki, ruaki, korere
– Ngā wera ki te waha, ki te korokoro, me te puku
– Ngā mate pāwera o te pūnaha io (hei tauira, te waikawa pūmua)
– Te kino o ngā whekau, inā koa te ate me te whatukuhu, i ētahi horopeta
– Te tūponotanga o te mate mēnā he paitini kino
Ko te mea e āwangawanga ake ana, kāore e kitea tonutia ngā pānga o te formaldehyde. Mēnā he iti noa te pānga engari ka maha tonu, ka pāngia pea koe e ngā raruraru hauora mō te wā roa.
4. Te Pūmanawa Matepukupuku
Kua whakarōpūtia te formaldehyde hei matū whakaputa mate pukupuku tangata e ētahi tari hauora o te ao. Ko te pānga roa, inā koa mā te manawa i roto i te taiao mahi, e hono ana ki te pikinga o te mōrearea ki te mate pukupuku o te ara manawa o runga. Ka piki ake tēnei mōrearea mēnā ka pā tonu ki te tangata me te kore he hauhautanga whakahaere me ngā taputapu tiaki whaiaro.
5. Ngā Pānga ki ngā Kaimahi me te Taiao
I roto i ngā rāngai ahumahi me ngā taiwhanga, ko ngā kaimahi e pāngia ana i ia rā te tino mōrearea. Ki te kore e tika te whakahaere mōrearea, ka horapa te pānga ki te taiao huri noa mā roto i ngā para wai, i ngā para kohu rānei. Nō reira, me penapena, me whakamahi, me maka atu hoki te formalin kia rite ki ngā tikanga mōrearea me ngā rauemi paitini (B3).
Te Whakamahi Kino i te Formalin i roto i te Kai: He aha i Tupu ai?
Ko te whakamahinga hē o te formalin i roto i te kai he mea ahu mai i ngā kaupapa ōhanga: ka taea e ia te hanga i ngā hua kia hou ake, kia mārō ake, kia roa ake hoki te ora. I ētahi wā, ka whakamahia hētia te formalin hei tiaki i ngā nūru mākū, te tōfu, te ika, te mīti tukatuka rānei kia kore ai e pirau.
Ko te raruraru, he uaua ki ngā kaihoko te wehewehe i waenga i te kai noa me te kai kei roto te formaldehyde mā te āhua noa iho. Ko ētahi o ngā āhuatanga e whakahuatia pinepinetia ana (ahakoa kāore i te tika i ngā wā katoa) ko te haunga kaha, te kakano tino ngaungau, te kakano pakari rānei, me te ātete ki te pāmahana tino teitei. Heoi, ko te tikanga tino tika ko te whakamātautau taiwhanga, ko te whakamātautau tere rānei e whakaratohia ana e ngā mana whakahaere.
Me pēhea te whakaiti i te mōrearea o te pānga ki te formaldehyde
He maha ngā mahi ārai nui ka taea te mahi, i ngā taumata takitahi me ngā taumata whakahaere.
1. Hei kaihoko, hoko kai mai i ngā puna pono, kia tūpato ki ngā kakara me ngā kakano rerekē, ā, karohia ngā hua "tino pumau" me te kore e rongoa ki te pouaka whakamātao.
2. Hei kaimahi taiwhanga/ahumahi, mauria he PPE katoa (he kopare manawa tika, he karapu ātete matū, he karu tiaki), kia pai te hauhautanga, ā, kia whai i ngā SOP.
3. Kia tika te penapena, me penapena te formalin ki roto i tētahi ipu kua kati pai, me te tohu mārama, kia kore e taea e ngā tamariki te toro atu, kia motuhake hoki i ngā taonga kaihoko.
4. Kaua te whakahaere para, te whakakorenga formalin e tūpono noa; me whai i ngā tikanga para B3 kia kore ai e poke te taiao.
Whakamutunga
He matū te formalin he nui ngā painga i roto i te rongoā, i ngā taiwhanga, me ngā ahumahi, ko te nuinga hei tiaki kiko me te rauemi mata mō te hanga kapia. Heoi, nā ōna āhuatanga paitini me te tauhohenga ka kino ki te tangata mēnā ka pāngia e te kore whakahaere, inā koa mēnā ka kainga mā te kai. Ko te whakamahinga hē o te formalin hei tiaki kai ka whakararu i te hauora o te marea, ā, me ārai mā te mātauranga, te tirotiro, me te whakamana ture. Mā te whakamahinga tika, ka taea te whakatutuki i ngā painga o te formalin me te kore e whakararu i te haumaru o te tangata me te taiao.
Ki te hiahia koe, ka taea e au te whakarerekē i tēnei tuhinga kia "mātauranga" ake (me ngā tohutoro me ngā tohutoro), kia rongonui ake rānei mō ngā maheni/kura, me te whakarite hoki kia tata tonu te maha o ngā kupu ki te 1000 kupu e hiahiatia ana.
