Ko te waro whakahohe, e kiia ana i ētahi wā ko te waro whakahohe, he mea mimiti ahurei e arohaina ana nā tōna hanganga tino pūngoi e taea ai te hopu me te pupuri i ngā rauemi.
E whakamahia whānuitia ana te waro whakahohe puta noa i ngā ahumahi maha hei tango i ngā wāhanga kāore e hiahiatia ana i roto i ngā wai, i ngā hau rānei, ā, ka taea te whakamahi i te waro whakahohe ki te maha o ngā tono e hiahia ana kia tangohia ngā poke, ngā rauemi kāore e hiahiatia ana rānei, mai i te purenga wai me te hau, ki te whakaora oneone, tae noa ki te whakaora koura.
Anei tētahi tirohanga whānui mō tēnei rauemi tino kanorau.
HE AHA TE WARO WHAKAHOHE?
He rauemi waro te waro whakahohe kua tukatukahia kia nui ake ai ōna āhuatanga mimiti, kia puta ai he rauemi mimiti pai rawa atu.
He hanganga pūwero whakamiharo tō te waro whakahohe, ā, he nui te mata hei hopu me te pupuri i ngā rauemi, ā, ka taea te whakaputa mai i ētahi rauemi waro whai rawa i te waro, tae atu ki:
Ngā anga kokonati
Rakau
Waro
Pīti
Ā, nui atu anō…
I runga i te rauemi pūtake, me ngā tikanga tukatuka i whakamahia hei whakaputa waro whakahohe, ka rerekē rawa ngā āhuatanga ā-tinana me te matū o te hua whakamutunga.² Ka hangaia he rārangi o ngā mea ka taea te rerekē i roto i ngā waro i hangaia ā-pākihi, me ngā rau momo e wātea ana. Nā tēnei, he tino motuhake ngā waro whakahohe i hangaia ā-pākihi hei whakatutuki i ngā hua pai rawa atu mō tētahi tono.
Ahakoa ēnei momo rerekētanga, e toru ngā momo matua o te waro whakahohe e hangaia ana:
Waro Whakahohe Paura (PAC)
Ko te nuinga o ngā waro whakahohe paura kei roto i te awhe rahi matūriki mai i te 5 ki te 150 Å, me ētahi rahi kei waho e wātea ana. Ko ngā PAC e whakamahia ana i roto i ngā tono mimiti wai-āhuatanga, ā, he iti ake ngā utu tukatuka me te ngāwari o te mahi.
Waro Whakahohe Matūriki (GAC)
Ko te rahi o ngā waro whakahohe kirikiri he 0.2 mm ki te 5 mm te nuinga, ā, ka taea te whakamahi i roto i ngā mahi hau me ngā mahi wai. He rongonui ngā GAC nā te mea he ma te whakahaere, ā, he roa ake te ora i ngā PAC.
Hei tāpiritanga, ka nui ake te kaha (te mārō) ā, ka taea te hanga hou me te whakamahi anō.
Waro Whakahohe Kua Whakaputaina (EAC)
He hua porotaka ngā waro whakahohe kua whakapūtāhia, mai i te 1 mm ki te 5 mm te rahi. He waro whakahohe taumaha ngā EAC e whakamahia whānuitia ana i roto i ngā tauhohenga hau, ā, he hua tēnei o te tukanga whakapūtāhia.
Ngā Momo Tāpiri
Ko ētahi atu momo waro whakahohe ko:
Waro Whakahohe Pītiti
Waro Whakakīia
Waro Panipani Polymer
Ngā Kakahu Waro Whakahohe
Ngā muka waro whakahohe
NGĀ ĀHUATANGA O TE WARO WHAKAHOHE
I te wā e whiriwhiri ana i te waro whakahohe mō tētahi whakamahinga motuhake, me whai whakaaro ki ngā āhuatanga maha:
Hanganga Pūwero
He rerekē te hanganga o ngā pūwero o te waro whakahohe, ā, ko te nuinga o te wā he hua nō te rauemi pūtake me te tikanga hanga.¹ Ko te hanganga o ngā pūwero, me ngā kaha kukume, te mea e āhei ai te mimiti.
Te pakeketanga/te pakū
He mea nui anō hoki te pakeke/te pakū. He maha ngā whakamahinga e hiahia ana kia kaha te matūriki o te waro whakahohe, kia ātete hoki ki te mimiti (te pakaru o te rauemi kia kikokore). Ko te waro whakahohe i hangaia mai i ngā anga kokonati te mea tino pakeke o ngā waro whakahohe.4
Ngā Āhuatanga Tāpiri
Kei roto i ngā āhuatanga mimiti o te waro whakahohe ētahi āhuatanga, tae atu ki te kaha mimiti, te tere mimiti, me te whai huatanga whānui o te waro whakahohe.4
I runga i te whakamahinga (wai, hau rānei), ka taea te tohu i ēnei āhuatanga e ētahi āhuatanga, tae atu ki te tau iodine, te horahanga mata, me te Mahi Waro Tetrachloride (CTC).4
Te Matotoru Āhua
Ahakoa kāore te mātotoru āhua e pā ki te mimiti mō ia taumaha, ka pā ki te mimiti mō ia rōrahi.4
Makuku
Ko te mea tino pai, ko te nui o te makuku ā-tinana kei roto i te waro whakahohe kia taka ki roto i te 3-6%.4
Te Ihirangi o te Pungarehu
Ko te nui o te pungarehu o te waro whakahohe he ine i te āhua o te rauemi, te āhua kore-ahua, te āhua kore-waro, me te kore e taea te whakamahi. Ko te mea pai ko te iti rawa o te nui o te pungarehu, nā te mea ka piki ake te kounga o te waro whakahohe i te hekenga o te nui o te pungarehu. 4
