Ngā Take Tuhi me ngā Take Pūngao

Kei ngā āhuatanga taiao pēnei i te wāhi, te huamoni, me te whakaheke ki te maha o ngā tūranga UV he nui ngā mahi i te whakarereke haere o ngā paripari. Ka taea e ngā wāhi mōhio kē te whakawehewehe i ngā hononga polimā, nō reira ka whakapakari ake te huamoni i te whakarerekētanga o te kōwhiri. Kei te whakatupu i te whakapaku me te mate i ngā āhuatanga mehana. Ko ngā rāngitaki ā-chemistry pēnei i ngā tohua me ngā āpure he mea hoki hei whakarerekē i te whakapono o ngā polimā, ka puta ki te wehe me te mate. Hei tauira, ka kitea e ngā paripari i te whakapā mai i ngā tohua nui ka mate pū ki wāhi roa. Ko ngā raraunga i roto i ngā rangahau taiao e whakaatu ana i te nui o tēnei whakarereke, ko tētahi i whakaatu ai he momo paripari e noho nei i raro i te whakapā moana o ngā tūranga UV ka whakarerekē ki te 50% i roto i tētahi tekau tau. I te hanga i ngā momo paripari, ko te aromatawai i te whakahokia ki te taiao he mea nui kia whakapakari i te whakarite i te whakarereke haere, kia tae noa atu te roa me te mahi.

Te Mahi a te Whakamama me ngā Pūtau Rā

Ko te whakatupu i ngā kaiwhakaawe ko tētahi take nui i te whakarereke o ngā pōria, e hāngai ana ki te whakawehenga o ngā raengaraenga me te whakapapa here. Ka tukua e tēnei mōhioiti rūkura te huringa ki te kaiwhakaae, ka whakawehenga ia i ngā raengaraenga o ngā pōria, ka heke te mana o ēnei. Ko ngā kaiwhakaae motuhake e whakaputa ana i te whakatupu, ka whiu atu tonu i te matamata haere o ngā pūkorero, ka whakapae atu i ngā wāhanga haere tuatahi. Hei tauira, ko ngā momo polyethylene e kitea nei te whakarereke haere i te wā, ka ngaro te wehewehenga me te mana o ēnei. Ko tētahi rangahau e whakaatu ana ko te noho mai o ngā kaiwhakaae motuhake ka tohu i te itinga o ngā pōria matua e 30%, e whakaatu ana i aua take whakamate. Ko ngā rangahau mai i ngā whenua whakapono, pērā i te Puka Mōhioiti o ngā Pōria, e tuku angitū ana i ngā mōhioiti roa mo te whakatupu o ngā kaiwhakaae motuhake me ō rātou mahi i roto i te wāhanga whakamate. Kāore i te whaihua te mōhio i ēnei take hei hanga i ngā whakaaturanga hei whakaiti i te whakarereke haere.

Te Whanonga ki ngā Pānga Mīhini

Te whakarerea o ngā rereke kotahi whanui ake i ngā āhuatanga mekanika, pērā i te mana maru, te whawhai atu ki te kaiwhakaaroaro, me te wheako. Ki te hangaia mai te whakarerea, ka hokona e ngā rereke kotahi i ō rātou tuhinga whakahaere, e hoheohetia ana te tūponotanga i ngā tūtohitanga e hiahiatia ana te manawa. Hei tauira, he rangahau i whakaatu i te 40% iti iho i te mana maru o te PVC i whakatakotoa ki te uru o ngā māngai UV. E taea ana ngā huringa i ēnei āhuatanga ki te whakapae mekanika, hei tauira ko ngā wā e kitea ai ngā wāhanga kua whakarerea i roto i ngā tūtohitanga motokā, ka puta ki te hokohoko i te mahi. Ko ngā taupara matatika i whakapā mai i te whakarerea ki te hokohoko i te mahi, e whakaū ana i te hiranga o te whiriwhiri i ngā rereke kotahi whakahirahira. Nō reira, e whakamahia ana ngā huringa i ngā āhuatanga mekanika i roto i ngā tūtohitanga takitahi, me te whiriwhiri pūtake i ngā rereke kotahi kia tino tūpato te whakahaere i te whakamana me te roa o ngā mahi i ngā tūtohitanga herehere.

Ngā Kīwai Whakangaro: Ngā Tipe me ngā Mahi

Ngā Kīwai Whakangaro (Phenolic, Organophosphorus)

Ko ngā tohenga whakamutu he mea nui i te whakatīngi i te wā o ngā hua plastic ki te whawhai i te whakamutu. Kia mahi rātou, ka tahuri i ngā kaiwhakahē hōhono e āheinga ana i te kauwae-rima pūmotu. Kei roto i te kāwanatanga tohenga whakamutu, ko ngā motu phenolic me ngā organophosphorus he motu nui. Ka mahi ngā tohenga whakamutu phenolic hei kai tuku hydrogen hei whakapā mai i ngā kaiwhakahē peroxide, kia noho e whakaheke nei i ngā takirua kauwhau e whakaroto i te pūmotu. Ki te taha hokuhoku, ka tohua ngā tohenga whakamutu organophosphorus i te whakatakoto o ngā peroxide ki ngā kaiwhakahē ake hoki, kia tiaki i te pūmotu. Kua whakaaturia ngā take whakamātau ko te whakamahi o ēnei mātauranga ka whakatika atu i te wā hoko o ngā plastic i waenganui i ngā tūranga, pērā i ngā wāhi motokā me te pākiri.

Nga Tauarahi Whakauru hei Piki i te Whakarere

Te whakatō i ngā wāhi whakamomori he mahi tūturu i te whakahaere mō ngā pūmau, kei te whakaiti i te whakarereke me te whakapai i te roanga o te kawe. Nā ngā tikanga pai e āheinga ana ki te whakahaere tika o ngā wāhanga wehewehe, o te wā porihitanga, me te paunga wai, e noho pono ana hei hanga i ngā whāinga me te roanga o te kawe tuatahi. Hei tauira, te whakahaere pai i te wāhanga momori e āhei ai ki te whakamutu i te whakarereke ā-wāhanga me te whakapai i te hāpai i te rautaki. Noaiho, te whakahaere pai i te wā porihitanga ka whakaiti i ngā mate ā-wāhanga i runga i te pūmau, me te whakapai i tana whiuwhenua.

Nā ngā rorohiko hanganga i whakaritea mai ko te whakapuakitanga o te turetanga matua o ēnei tauarahi ka puta he pai ake ngā horopaki mekanika, ā, te roa o ngā pūoro. Ko ngā ture me ngā tohutohu ahumahi e whai wāhi ana ki te whakaratonga i ēnei tauarahi kia mōhio ai ngā hangaenga i te whakamahinga i ngā taonga pai, hirawea. He mea nui te mōhio i te hononga kotahi i waenganui i ngā momo hanga me ngā tuhituhi o ngā rauropi hei tiaki i te whakaiti i te korekore i te wā o te hanga.

Ngā Whakaaturanga Hanganga ki te Whakaiti i ngā Pūnaha Whētau

Ki runga i te hanga o ngā tahuhu pūoro, ka puta ngā pūnaha whētau ki te korenga mō te wā, me whakamahi i ngā whakaaturanga e āheinga ana i ēnei take. Ko ngā momo hanga pūroro, ko te whakatutuki i te paoro kotahi, ko te whakatika i ngā heke hei whakauru i ngā pūnaha whētau. E āwhina ana ēnei whakaaturanga ki te whakaiti i ngā whētau whenua e āhei ana ki te whakapaihere i ngā rauropi i raro i te pūnaha.

Kei te whakamahara ngā ture hanga i waenganui i ngā tikanga hanga hei whakarite i ēnei tūtohu. Ko te whakaaturanga i ngā momo whakapae kē ka tae atu ki te kitea he wāhi e āheinga ana i ngā panoni rerekē rānei, he paoro rerekē rānei, hei whakawātea i ngā pūnaha tohu paihori. Kei te whakahau i ēnei rōpū matua me ngā kaihanga take kei te whakarite ki ēnei tikanga hei whakapai i te roanga o te mahi me te whakarite. Ko te whakamahi i ēnei matatika paihere hei whakapai i te whiuwhenua tuatahi o ngā whatu paihori, ā, hei whakawhanake hoki i te tirotiro me te mahi i roto i ngā tono whakamātau.

Nga Painga me nga Whakamahinga i te Ao Tōnui

Whakahaere Motokā: Ngā Wāhi Whakahirahira i Raro i te Kapa

Kei roto i te pūtake whakahaere motokā, e hia顿顿ngā mātāmua e whakamahia mo ngā kōmponenti i raro i te kapa, kia tae ki ngā ture matatika mo te whai wawanga me te whiuwhiu ki ngā waehu nui. E ai ki ngā kōmponenti nei, e takoto ana ki ngā āhuatanga iti-kore, he mea hiahia ngā mātāmua kia taea te whiuwhiu i ngā taiao kino, ki te kore e whakaritea te haumaru me te pai o te mahi. Nā ngā pākete whakaritea, me ngā whenu whakatika anti-aging, ka whakahīnaki i te roanga o ēnei kōmponenti, ki te kore e mate i te whakaputuputu me te whakapakoko i ngā waewae. He mea kitea i ngā raraunga i roto i te pūtake motokā, ko te mea whakatipu ngā pākete whakaritea i te oranga motokā me te itinga i ngā huringa whakahaere. Hei tauira, ko te kawe ake i ngā mātāmua whakamua i roto i ngā whakahaere i raro i te kapa, ka whakaiti i te whakamate ā-waha me te kōpikopiko, ka whakapai anō hoki i te whakaheke me te roanga o te raupapa.

Ngā Pūtake Waho: Ngā Whakatakotoranga Whakauru UV

Te whaihua o te mōhio ki te upoko kaiwhakarite UV mo ngā mea hanga noa iho, pēnei i ngā whakapae whenua me ngā tūtohu hanga, inaianei kei raro i te whakaaweawe o te rā. Ki te kore e āhei ana te tiaki i aua rauemi, ka kitea he wā ka horoia rātou ki te reka, e whiwhi ana ki te hunaanga ā-wawata me te pai ake o te tirohanga. Ko te whakauru i ngā whakautu e āheinga ana i te wehiwehi UV ki roto i ngā poraka, he mea nui tēnā hei whakatika i te horomana, hei whakamana i te roa mō te wā e hīkina nei. Ki te pūrongo whai take, he nui ake te tono mo ngā rauemi e āhei ana ki te whakatakoto i runga i te wehiwehi UV, inaianei kei raro i te roa pai rawa atu i te ao marangai. Hei tauira, ko ngā pūrongo matua e whakaatu ana i ngā paihere o te whakamahere i ngā poraka whakahirahira i tēnei tūmomo whakamahi, e whakaatu ana i te whakapai hoki i te whiuwhiu tuhituhinga me te roa haere e whai ana i te hunga whakarerea rawa.

Ngā Tuhinga Whakamahere Mō te Tangata: Ngā Kākahu Nui

He hāngai tēnei i ngā rauemi whakamahi i te ao whakamārama ki ngā matāpuhi e āhei ana kia whai mana me te roa tonu hei whakarite i ngā mahi me te āhua nui mō te wā. Nā ngā whare whakauru i hanga mai i ngā pūoro matatika ka puta ai tēnei, nā te whakauru i ngā painga e tiaki ana i te korekorenga.
