Te pupuhi i te pahū: he ruku mātao ki te wetewete pahū peita i te tau 2025

E hoa, kei te pēhea? Mēnā kei te hōhonu koe ki te ao o ngā peita me ngā kapi, pēnei i ahau – āe, ko au tērā tangata kua whakapau tau e rangahau ana i ngā tāpiri hei whakarite kia tino pai tō mahi peita – ka mōhio koe he tino whakangaro i te ngahau te pūwha. Whakaarohia koe e whakaranu ana i tētahi peita pakitara hou, ā, ka pūwha ake pēnei i tētahi ipu wai soda kua wiri. Paruparu, nē rā? Hei tohunga mō ngā kai whakakore pahū i roto i te peita, kua kite au i ngā mea katoa, mai i ngā aitua mahi-a-ringa ki ngā raruraru ahumahi. I roto i tēnei tuhinga ngāwari, ka wetewete au he aha ēnei kai whakawhiwhi mīharo, ngā momo e whakamahia ana i te tau 2025, me pēhea te whakamahi, ā, he aha ngā āhuatanga wera o ngā ahunga hou. Kāore he akoranga hōhā, he kōrero mārama noa iho hei āwhina kia maeneene tonu ngā mahi. Me pahū tātou i ēnei pahū!

Tuatahi: he aha te take e puta mai ai te pūhā i roto i ngā peita? Nō te hau e whiua ana i te wā e whakaranu, e pupuhi, e whakamahi rānei. Ko ngā matū whakakōpeke – ēnei matū ngohengohe e āwhina ana kia rere, kia piri te peita – ko ngā hoa piri rawa o te pūhā, e whakakaha ana i ngā pūpū e arahi ana ki ngā hē āhua pērā i ngā kohao iti, ngā rua hohonu, ngā whakaoti rārangi rānei. I roto i ngā peita wai, e kitea ana huri noa i ēnei rā mō tō rātou āhua taiao, he tino huna te pūpū. Kua whakatika au i ngā mahi maha kāore i taea te tatau i huri ai te koti a te tohunga hei mahi a te tauhou nā te pūpū kāore i āta tirohia. Engari ko ngā kaiwhakakore pūpū? Ko rātou ngā kaiwhakatika, he tāpiri e ārai ana i te hanga pūpū, e pahua wawe ana i te wā ka puta. Ka mahi rātou mā te whakaiti i te kaha ā-mata o te wai, ka horapa ki runga i ngā pūpū, ā, ka whakangaro i a rātou. Pā! Kua oti te raru.

Ināianei, me kōrero tātou mō ngā momo, nā te mea kāore ngā kaiwhakakore pūwha katoa e hāngai ana ki ngā āhuatanga katoa. Ko ngā mea i hangaia ki te kirikoni tonu ngā tino toa mō te tau 2025, e rangatira ana i te ao mō tō rātou whaihua whakamīharo i roto i ngā kapi wai. Ka tere rātou ki te tohatoha, ka whakangaro i te pūwha me te kore aroha, ā, ka pai hoki tō rātou mahi tahi ki te nuinga o ngā pūhui. Me whakaaro ki ngā peita hanganga, ki ngā whakaoti waka rānei – ka whakahaere ngā kirikoni i ēnei mahi pērā i ngā toa. Engari kia tupato: ka nui rawa te whakamahi ka puta he ’kanohi ika,“ arā, ngā wāhi hinu e whakangaro ana i tō kanapa. I Haina, kei te puāwai te mākete, ā, ko ngā kai whakakore pūwha hinu kohuke e mau ana i te 80% o te wāhanga, he tino pai mō ngā peita whakamahia ana i ngā whakamomori pērā i ngā alkyd me ngā epoxy. He iti ake ā rātou utu, ka whakamahi i ngā wāhanga whakahāparangi wai hei patu i ngā pūwha, ā, kāore e pā kino ki te piri. Ka riro i ngā kai whakakore pūkahukahu polyether he wāhanga iti ake, arā ko te 3%, engari kei te piki haere tō rātou rongonui mō ngā mahi taiao-hoa. Kāore hoki e warewarehia ngā kōwhiringa i runga i te polymer; e tata ana tō rātou uara ki te $69.54 miriona i tēnei tau, ā, kei te tipu i te 3.6% CAGR. He tino whaihua ēnei mō ngā tono uaua e hinga ana ngā tikanga tuku iho.

He aha ngā whakamahinga? Kei ngā wai peita katoa ngā kai whakakore pahū – mai i tō peita latex whakahou whare ki ngā kapi ahumahi taumaha. I te tau 2025, he tino hira ēnei mō ngā raina whakaputa tere, nā te mea ka whakaroa te pahū i ngā mahi katoa. Mō ngā kapi wai-ā-wera, e piki haere ana tō rātou rongonui nā ngā ture VOC, ko ngā kirīkonī te kōwhiringa matua, nā te mea ka whakakore i te pahū i roto i ngā ranunga wai. Kua whakamahia e au ēnei i ngā peita moana hei whawhai i te pahū wai tote, i ngā hanganga kai rānei – āe, i whakarewahia e BASF he hanga hou i Maehe mō ngā raina whakamāori me te whakakī. Hei whakarāpopoto: me kore ngā kai whakakore pahū, ka nui ake ngā hē, ka ngaro te wā, ā, ka piki ngā utu. I ngā wheketere, ka whakapiki i te whaihua; mō te hunga mahi ā-ringa, he pakitara kore pahū, ātaahua, ā, he āhua ngaio.

Me pēhea koe e whakaoho ai i ēnei kia mahi? He māmā noa. Tāpirihia i te tīmatanga – i muri i ngā tae, i mua i te whakaranu taumaha – i waenga i te 0.1% ki te 1% mā te taumaha. Whakamātauria ngā kohinga iti: korikoritia, tatari, ā, tirohia te pupuhi e ngaro ana. Mēnā ka noho tonu, whakatikatikahia te rahinga, te momo rānei. He nekehanga mātanga: kia hāngai ki te āhua o tō peita. Hei whakamahi ā-roto? He kakara iti, he pai mō ngā VOC. Mō te puha? Ngā momo e aukati ana i te shear, kāore e ngoikore i waenganui i te mahi. Kua karo ahau i ngā aitua mā te tirotiro i te hototahitanga ki ngā kaiwhakakaha – ki te hē, ka wehe tō peita pēnei i te hinu me te wai.

Engari he raruraru? Ae, he tūturu. Ki te nui rawa te whakamahi, ka puehu hinu; ki te iti rawa, ka rangatira te puehu. He mea nui te roa o te penapena – me penapena i te wāhi makariri, ā, kia kapi pai. Ā, i te tau 2025, kia mataara ki ngā here pērā i ngā matū horoi-puehu iti-puehu e tū ana hei kaiwhakahaere matua, e whakapai ana i ngā tukanga kia iti ake te hiahia mō te kai whakakore puehu. Heoi anō, kei te mura tonu te mākete: kua eke ngā kaiwhakakore pūpū peita ki te $6.07 piriona i tēnei tau, ā, e aro ana ki te 16.54% CAGR kia eke ki te $15.21 piriona ā te tau 2033. Ngā tāpiri whakakore pūrepo ā-ao? $2.05 piriona i te tau 2024, e piki ana ki te $2.98 piriona ā te tau 2033. He aha te take o tēnei pikinga? Nā ngā ture taiao mārō ake e whakakore ana i ngā matū whai VOC teitei, me ngā auahatanga mō ngā whakamahinga motuhake, pērā i ngā kaiwhakakore pūrepo kua whakaritea mō ngā tono motuhake.

Ki te anga whakamua, ko ngā ahunga o te tau 2025 e pā ana ki te kākāriki me te mātau. Kei te piki haere ngā kai whakakore pūpū i ahu mai i ngā otaota, hei karo i te whakahē o te hinu. Kei roto hoki te hangarau nano hei pahua pūpū motuhake, ā, me te whakawhānui haere o ngā kirihou-silicone kai-āhua, tumanako ka nui ake ngā whakawhitinga ki te tunu pia me te rāngai rongoā. He whakamīharo – ehara i te mea kei te whakakore pūpū anake mātou; kei te auaha mātou mō tētahi anamata toitū. Kua tohutohu ahau i ngā kaupapa mahi i reira i whakaitia ai ngā hapa e 25% mā te whakawhiti ki ēnei, ā, i penapena moni me te tiaki i te ao.

Nō reira, mēnā kei te raru koe i te puehu, whakakīa tō ringa ki te kaiwhakakore puehu peita tika. Ahakoa he kaiwhakatikatika i te garāhi koe, he rangatira wheketere rānei, he tino whakarerekē ēnei tāpiritanga. He pātai āu? Tukua mai ki ahau – kei konei au hei pupuri i ō peita kia kanapa (i te huarahi pai). Kia maeneene tonu koe i waho!
