Nā uhi wai: He kahawai mau o nā hoʻomohala

Pehea ke kūlana ma ka mākeke o nā uhi wai?

He maikaʻi mau nā wānana mākeke e like me ka mea e manaʻo ʻia no kahi ʻāpana i hoʻoikaika ʻia e kona kūlike me ke kaiapuni. Akā, ʻaʻole nā ​​​​palapala hōʻoia eco nā mea āpau, me ke kumukūʻai a me ka maʻalahi o ka noi ʻana he mea nui ia e noʻonoʻo ʻia.

Ua ʻaelike nā ʻoihana noiʻi i ka ulu mau ʻana no ka mākeke uhi wai honua. Hōʻike ʻo Vantage Market Research i kahi waiwai o EUR 90.6 biliona no ka mākeke honua i ka makahiki 2021 a kuhi ʻia e hōʻea i kahi waiwai o EUR 110 biliona ma ka makahiki 2028, ma kahi CAGR o 3.3% ma luna o ka wā wānana.

Hāʻawi ʻo Markets and Markets i kahi loiloi like o ka ʻāpana wai i ka makahiki 2021, ma EUR 91.5 biliona, me kahi CAGR ʻoi aku ka maikaʻi o 3.8% mai 2022 a i 2027 e hiki i ka EUR 114.7 biliona. Manaʻo ka ʻoihana e hiki ka mākeke i ka EUR 129.8 biliona ma ka makahiki 2030 me ka piʻi ʻana o ka CAGR i 4.2% mai 2028 a i 2030.

Kākoʻo ka ʻikepili a IRL i kēia manaʻo, me ka CAGR holoʻokoʻa o 4% no ka mākeke wai, i kēia manawa no ka wā 2021 a 2026. Hāʻawi ʻia nā kumukūʻai no nā ʻāpana pākahi ma lalo nei a hāʻawi i nā ʻike nui aʻe.

Ka laulā no ka māhele mākeke nui aʻe

ʻO nā uhi hale e hoʻomalu nei i ka huina o nā kūʻai aku honua a me ka nui e helu ana ma mua o 80% o ka māhele mākeke e like me IRL, nāna i hōʻike i ka nui o 27.5 miliona tone no kēia māhele huahana i ka makahiki 2021. Manaʻo ʻia kēia e hiki i kahi kokoke i 33.2 miliona tone ma ka makahiki 2026, e piʻi mau ana ma kahi CAGR o 3.8%. ʻO kēia ulu ʻana ma muli o ka hoʻonui ʻia o ke koi ma muli o nā hana kūkulu ma mua o kahi hoʻololi nui mai nā ʻano uhi ʻē aʻe i hāʻawi ʻia he noi kēia kahi i loaʻa ai kahi wāwae ikaika o nā uhi wai.

ʻO ke kaʻa ka lua o ka ʻāpana nui loa me ka ulu makahiki hui o 3.6%. Kākoʻo ʻia kēia i kahi nui e ka hoʻonui ʻana o ka hana kaʻa ma Asia, ʻo Kina a me India hoʻi, ma muli o ke koi a ka mea kūʻai.

ʻO nā noi hoihoi me ka laulā no nā uhi wai e hopu i kahi mahele nui aʻe i nā makahiki e hiki mai ana e komo pū me nā uhi lāʻau ʻoihana. E kōkua nā hoʻomohala ʻenehana i ka piʻi olakino o ka māhele mākeke ma lalo iki o 5% ma kēia ʻāpana - mai 26.1% i ka makahiki 2021 a i kahi 30.9% i wānana ʻia i ka makahiki 2026 e like me IRL. ʻOiai ʻo nā noi moana e hōʻike ana i ka ʻāpana noi liʻiliʻi loa i hōʻike ʻia ma 0.2% o ka mākeke wai holoʻokoʻa, hōʻike kēia i ka piʻi ʻana o 21,000 metric tonnes ma luna o 5 mau makahiki, ma kahi CAGR o 8.3%.

Nā mea hoʻokele ʻāpana

Ma kahi o 22% wale nō o nā uhi āpau ma ʻEulopa e lawe ʻia ana e ka wai [Akkeman, 2021]. Eia nō naʻe, ma kahi ʻāina kahi e hoʻokele nui ʻia ai ka noiʻi a me ka hoʻomohala ʻana e nā lula e hoʻohaʻahaʻa i nā VOC, e like me ke ʻano ma ʻAmelika ʻĀkau, ua lilo nā uhi wai e pani ai i nā mea i loaʻa nā mea hoʻoheheʻe i wahi noiʻi. ʻO nā noi kaʻa, pale a me ka uhi lāʻau nā wahi ulu nui.

Ma Asia-Pākīpika, ʻoiai ʻo Kina a me India, ʻo nā mea hoʻokele mākeke koʻikoʻi e pili ana i ka hana kūkulu wikiwiki ʻana, ke kūlanakauhale ʻana a me ka hoʻonui ʻia ʻana o ka hana kaʻa a e hoʻomau i ke alakaʻi ʻana i ke koi. Aia nō ka laulā nui no Asia-Pākīpika ma mua o ke kūkulu hale a me ke kaʻa, no ka laʻana, ma muli o ka piʻi ʻana o ke koi no nā lako lāʻau a me nā lako uila e pōmaikaʻi nui ana mai nā uhi wai.

Ma ka honua holoʻokoʻa, ʻo ke kaomi mau ʻana ma luna o ka ʻoihana a me ke koi a nā mea kūʻai aku no ka hoʻomau nui ʻana e hōʻoiaʻiʻo ana e hoʻomau ka ʻāpana wai i mea nui no ka hana hou a me ka hoʻopukapuka kālā.

Hoʻohana nui ʻia nā resins acrylic

ʻO nā resins acrylic kahi papa ulu wikiwiki o nā resins uhi i hoʻohana ʻia ma nā ʻano noi like ʻole no ko lākou ʻano kemika a me ka mechanical a me nā waiwai aesthetic. Loaʻa i nā uhi acrylic i lawe ʻia i ka wai kahi helu kiʻekiʻe i nā loiloi pōʻaiapuni ola a ʻike i ke koi ikaika loa i nā ʻōnaehana no nā noi kaʻa, kuhikuhipuʻuone a me ke kūkulu ʻana. Ua wānana ʻo Vantage e helu ka kemika acrylic ma mua o 15% o ka huina kūʻai aku ma ka makahiki 2028.

Hōʻike pū nā resins uhi epoxy a me polyurethane i ka wai i nā ʻāpana ulu kiʻekiʻe.

Nā pōmaikaʻi nui i ka ʻāpana wai ʻoiai ke mau nei nā pilikia nui

ʻO ke kūkulu ʻōmaʻomaʻo a me ka hoʻomau mau ʻana e kau maoli i ka nānā ʻana i nā uhi wai no ko lākou kūlike ʻana i ke kaiapuni i hoʻohālikelike ʻia me nā koho ʻē aʻe i lawe ʻia e ka solvent. Me ka liʻiliʻi a ʻole ka nui o nā mea hoʻohuihui organik volatile a i ʻole nā ​​​​mea haumia ea, paipai nā lula paʻa i ka hoʻohana ʻana i nā kemika wai i lawe ʻia ma ke ʻano he ala e kaupalena ai i nā hoʻokuʻu ʻana a pane i ke koi no nā huahana ʻoi aku ka aloha i ke kaiapuni. Ke ʻimi nei nā hana hou ʻenehana hou e maʻalahi i ka hoʻohana ʻana i ka ʻenehana wai i lawe ʻia ma nā ʻāpana mākeke i ʻoi aku ka makemake e hoʻololi ma muli o nā hopohopo kumukūʻai a me ka hana.

ʻAʻohe mea e pakele ai mai ke kumukūʻai kiʻekiʻe e pili ana me nā ʻōnaehana wai, inā paha e pili ana i ka hoʻopukapuka kālā ʻana i ka R&D, nā laina hana a i ʻole ka hoʻohana maoli ʻana, ka mea e koi pinepine ai i kahi pae kiʻekiʻe o ka ʻike loea. ʻO ka piʻi ʻana o nā kumukūʻai i hala koke nei i nā mea maka, ka lako a me nā hana e hoʻolilo i kēia i mea noʻonoʻo nui.

Eia kekahi, ʻo ka loaʻa ʻana o ka wai i loko o nā uhi ʻana he pilikia ia i nā kūlana kahi e hoʻopilikia ai ka haʻahaʻa a me ka mahana i ka maloʻo ʻana. Hoʻopilikia kēia i ka hoʻohana ʻana i ka ʻenehana wai no nā noi ʻoihana ma nā wahi e like me ka Hikina Waena a me Asia-Pākīpika ke ʻole hiki ke hoʻomalu maʻalahi ʻia nā kūlana - e like me ka hiki me nā noi kaʻa e hoʻohana ana i ka hoʻōla wela kiʻekiʻe.

Ma hope o ke kālā

Kākoʻo nā hoʻopukapuka hou e nā mea pāʻani nui i nā ʻano mākeke i wānana ʻia:

• Ua hoʻopukapuka ʻo PPG ma mua o EUR 9 miliona e hoʻonui i kāna hana ʻEulopa o nā uhi OEM kaʻa e hana i nā basecoats i lawe ʻia e ka wai.
• Ma Kina, ua hoʻopukapuka kālā ʻo Akzo Nobel i kahi laina hana hou no nā uhi wai. Hoʻonui kēia i ka hiki ke hana e like me ka manaʻo e hoʻonui ʻia ana ke koi no nā pena wai VOC haʻahaʻa no ka ʻāina. ʻO nā mea pāʻani mākeke ʻē aʻe e hoʻohana ana i nā manawa kūpono ma kēia ʻāina ʻo Axalta, nāna i kūkulu i kahi hale hana hou e hoʻolako i ka mākeke kaʻa ulu o Kina.

Manaʻo kōkua no ka hanana

ʻO nā ʻōnaehana wai-wai kekahi ke kikowaena o ka EC Conference Bio-based and Water-based Coatings ma Nowemapa 14 a me 15 ma Pelelina, Kelemānia.Ma ka ʻaha kūkā e aʻo ʻoe e pili ana i nā hoʻomohala hou loa i nā uhi bio-based a me nā uhi wai.
