Kuhi ʻia ka mākeke honua no nā uhi lāʻau ʻoihana e ulu ma 3.8% CAGR ma waena o 2022 a me 2027 me nā lako lāʻau ka ʻāpana kiʻekiʻe loa. Wahi a ka PRA hou loa ʻo Irfab Industrial Wood Coatings Market Study, ua manaʻo ʻia ke koi ʻana o ka mākeke honua no nā uhi lāʻau ʻoihana ma kahi o 3 miliona tons (2.4 biliona lita) i 2022. Na Richard Kennedy, PRA, a me Sarah Silva, ka mea hoʻoponopono kōkua.

Aia i loko o ka mākeke no nā ʻāpana lāʻau ʻokoʻa ʻekolu:
- Nā lako lāʻau: Nā pena a i ʻole nā varnishs i hoʻohana ʻia i nā lako hale, kīhini a me nā lako keʻena.
- ʻO ka hui pū ʻana: Nā pena i hoʻohana ʻia i ka hale hana a me nā varnish i nā puka, nā pā pukaaniani, nā ʻoki a me nā keʻena.
- Ka papahele lāʻau i hoʻopau mua ʻia: Hoʻohana ʻia nā varnish i hoʻohana ʻia i ka hale hana i nā laminates a me nā papahele lāʻau i hana ʻia.
ʻO ka ʻāpana nui loa ʻo ia ka ʻāpana lāʻau lāʻau, e helu ana no 74% o ka mākeke uhi lāʻau ʻoihana honua ma 2022. ʻO ka mākeke kūloko nui loa ʻo Asia Pacific me ka 58% o ka noi o ka honua no nā pena a me nā varnish i hoʻohana ʻia i nā lako lāʻau, a ukali ʻia e ʻEulopa me kahi o 25%. ʻO ka ʻāina ʻo Asia Pākīpika kekahi o nā mākeke nui no nā lako lāʻau i kākoʻo ʻia e ka piʻi nui ʻana o ka heluna kanaka o Kina a me India.
He mea nui ka pono o ka ikehu
ʻO ka hana ʻana o kēlā me kēia ʻano mea lako he mea maʻamau, hoʻololi ʻia e nā hanana hoʻokele waiwai a me ka hoʻomohala ʻana i nā mākeke hale ʻāina a me ka loaʻa kālā hoʻolimalima hale. Ke hilinaʻi nei ka ʻoihana hale lāʻau i nā mākeke kūloko a ʻoi aku ka liʻiliʻi o ka hana ʻana i ka honua ma mua o nā ʻano mea lako ʻē aʻe.
Hoʻomau ka loaʻa ʻana o nā huahana wai wai i ka māhele mākeke, alakaʻi nui ʻia e nā hoʻoponopono VOC a me ka koi o nā mea kūʻai aku no nā huahana pili i ka kaiapuni, me ka neʻe ʻana i nā ʻōnaehana polymer kiʻekiʻe e pili ana i ka self-crosslinking a i ʻole 2K polyurethane dispersions. Hiki iā Mojca Šemen, ka Luna Hoʻokele no ka Industrial Wood Coatings ma ka Kansai Helios Group, ke hōʻoia i ka koi kiʻekiʻe no ka uhi ʻana i ka wai, e hāʻawi ana i nā mea maikaʻi ma mua o nā ʻenehana solvent-borne. Ke hoʻomau nei ka makemake i ka ulu ʻana "ʻoi aku ka nui o nā mea kūʻai aku ma mua o ka hoʻomau a me ke kuleana o ke kaiapuni i kā lākou hoʻoholo kūʻai."
Eia nō naʻe, hoʻomau ka hoʻopuehu ʻana o ka acrylic, nā ʻenehana i lawe ʻia i ka solvent i ka ʻāpana o nā lako lāʻau. ʻO nā uhi uhi hiki ke ho'ōla ʻia o UV ke kaulana loa no nā lako (a me ka papahele) ma muli o kā lākou hana ʻoi aku ka maikaʻi, ka wikiwiki o ka hoʻōla a me ka ikaika kiʻekiʻe. ʻO ka neʻe ʻana mai nā kukui mercury maʻamau i nā ʻōnaehana kukui LED e hoʻonui hou i ka ikehu a hoʻemi i nā kumukūʻai pani kukui. Ua ʻae ʻo Šemen e piʻi mai ana ke ʻano o ka hoʻōla ʻana o LED, e hāʻawi ana i nā manawa hoʻōla wikiwiki a me ka emi ʻana o ka ikehu. Ua wānana ʻo ia i ka hoʻohana nui ʻana i nā ʻāpana bio-based i ka ʻimi ʻana o nā mea kūʻai aku i ka uhi ʻana i nā huahana me ka hopena haʻahaʻa o ke kaiapuni, kahi ʻano e alakaʻi nei i ka hoʻohui ʻia ʻana o nā resins kumu lāʻau a me nā aila kūlohelohe, no ka laʻana.
ʻOiai ʻo ka 1K a me ka 2K ka uhi ʻana i ka wai e ʻoliʻoli i ka kaulana ma muli o ko lākou mau ʻike kaiapuni, ua kākau ʻo Kansai Helios i kahi moʻolelo koʻikoʻi: "E pili ana i ka 2K PU coatings, manaʻo mākou e emi mālie ko lākou ʻai ʻana ma muli o nā palena o nā mea paʻakikī e hoʻomaka i ka hopena ma ʻAukake 23, 2023.
Hoʻokūkū paʻakikī nā mea ʻē aʻe
ʻO ka lua o ka ʻāpana nui loa ʻo nā uhi i hoʻopili ʻia i ka hui ʻana me ka 23% o ka māhele o ka mākeke uhi lāʻau ʻoihana honua. ʻO ka ʻāina ʻo Asia Pacific ka mākeke kūloko nui loa me kahi 54% kahele, a ukali ʻia e ʻEulopa me 22%. Hoʻoikaika nui ʻia ka noi e ke kūkulu hale hou a i kahi pae liʻiliʻi e ka mākeke pani. ʻO ka hoʻohana ʻana i ka lāʻau ma nā hale noho a me nā ʻoihana kūʻai ke kū nei i ka hoʻokūkū nui mai nā mea ʻē aʻe e like me ka uPVC, composite a me nā puka alumini, nā puka makani a me nā ʻoki, e hāʻawi ana i ka mālama haʻahaʻa a ʻoi aku ka hoʻokūkū ma ke kumukūʻai. ʻOiai ka maikaʻi o ke kaiapuni o ka hoʻohana ʻana i ka lāʻau no ka hoʻohui ʻana, ʻoi aku ka nāwaliwali o ka ulu ʻana o ka hoʻohana ʻana i ka lāʻau no nā puka, nā puka makani a me nā ʻoki ma ʻEulopa a me ʻAmelika ʻAmelika e hoʻohālikelike ʻia i ka ulu ʻana o kēia mau mea ʻē aʻe. ʻOi aku ka ikaika o ka noi ʻana i ka lāʻau ma nā ʻāina he nui ma Asia Pacific ma muli o ka hoʻonui ʻia ʻana o nā papahana hale noho a me ke kūkulu ʻana i nā hale kūʻai, e like me nā keʻena a me nā hōkele, e pane ana i ka ulu ʻana o ka heluna kanaka, ka hoʻokumu ʻana o ka hale a me ke kūlanakauhale.
Hoʻohana nui ʻia nā mea hoʻoheheʻe ʻia no ka uhi ʻana i nā mea hoʻohui e like me nā puka, nā puka makani a me nā ʻoki, a e hoʻomau nā ʻōnaehana polyurethane me ka solvent-borne i ka hoʻohana ʻana i nā huahana kiʻekiʻe. Makemake kekahi mau mea hana puka aniani i nā mea hoʻoheheʻe ʻia ma muli o ka hopohopo i ka pehu ʻana o ka lāʻau a me ka hāpai ʻana i ka palaoa ma muli o ka hoʻohana ʻana i nā uhi wai. Eia nō naʻe, i ka piʻi ʻana o ka hopohopo kaiapuni a ʻoi aku ka paʻakikī o nā kūlana hoʻoponopono a puni ka honua, ke ʻimi nei nā mea hoʻopili uhi i nā mea ʻē aʻe i lawe ʻia i ka wai, ʻoi aku ka polyurethane-based system. Hoʻohana kekahi mau mea hana puka i nā ʻōnaehana hoʻōla radiation. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i nā varnish hiki ke hoʻōla ʻia UV ma nā waihona pālahalaha, e like me nā puka, e hāʻawi ana i ka hoʻomaikaʻi ʻana i ka abrasion, ke kūpaʻa kemika a me ka pale ʻana i ka ʻili: hoʻōla ʻia kekahi mau uhi puaʻa ma nā puka e ke kukui uila.
ʻO ka ʻāpana o ka papa lāʻau ka mea liʻiliʻi loa o nā ʻāpana ʻekolu me kahi o 3% o ka mākeke uhi lāʻau ʻoihana honua, me ka ʻāina ʻo Asia-Pākīpika e helu ana ma kahi o 55% o ka mākeke papa lāʻau honua.
Ua koho ʻia nā ʻenehana uhi UV no nā mea he nui
Ma ka mākeke papahele o kēia lā, ʻekolu mau ʻano papahele lāʻau, e hoʻokūkū pū ana me nā ʻano papahele ʻē aʻe, e like me ka papahele vinyl a me nā kile seramika, ma nā hale noho a me nā hale noho ʻole: ka papahele lāʻau paʻa a paʻa paha, ka papahele lāʻau i hana ʻia a me ka papahele laminate (ʻo ia kahi huahana lāʻau hopena). ʻO nā lāʻau i hana ʻia a pau, ka papahele laminate a me ka hapa nui o ka papahele paʻa a paʻa paha i pau i ka hale hana.
Hoʻohana maʻamau ʻia nā ʻāpana polyurethane ma nā papahele lāʻau ma muli o ko lākou maʻalahi, paʻakikī a me ke kūpaʻa kemika. ʻO nā holomua nui o ka alkyd a me ka ʻenehana polyurethane (ʻoi aku ka polyurethane dispersions) ua kōkua i ka hoʻokumu ʻana i nā uhi wai-wai hou e hiki ke hoʻohālikelike i nā waiwai o nā ʻōnaehana hoʻoheheʻe. Ua hoʻokō kēia mau ʻenehana i hoʻomaikaʻi ʻia i nā lula VOC a ua wikiwiki i ka neʻe ʻana i nā ʻōnaehana wai no ka papahele lāʻau. ʻO nā ʻenehana uhi UV ka mea i koho ʻia no nā ʻoihana he nui ma muli o ko lākou hoʻohana ʻana i nā papa pālahalaha, e hāʻawi ana i ka hoʻōla wikiwiki, abrasion koʻikoʻi a me ka pale ʻana.
ʻO ke kūkulu ʻana i ka ulu ʻana akā ʻoi aku ka nui o ka hiki
Ma ka maʻamau me ka mākeke hoʻolālā hale ma ka laulā, ʻo nā mea hoʻokele nui no ka uhi lāʻau ʻoihana he hana hou o nā hale noho a me nā hale noho ʻole, a me ka hoʻomaikaʻi ʻana i ka waiwai (ʻo ia kekahi i kākoʻo ʻia e ka hoʻonui ʻana i ka loaʻa kālā ma nā wahi he nui o ka honua). Kākoʻo ʻia ka pono o ke kūkulu ʻana i nā hale noho e ka ulu ʻana o ka heluna kanaka a me ka hoʻonui ʻana i ke kūlanakauhale. No nā makahiki he nui, he mea nui ka hopohopo nui o ka hale kūʻai i ka hapa nui o nā ʻāina o ka honua a hiki ke hoʻoholo maoli ʻia ma ka hoʻonui ʻana i ka waihona hale.
Mai ka hiʻohiʻona o ka mea hana, ʻōlelo ʻo Mojca Šemen i kahi paʻakikī koʻikoʻi e like me ka hōʻoia ʻana i ka maikaʻi o nā mea i hoʻohana ʻia e like me ka hopena hopena maikaʻi loa e hilinaʻi ʻia i nā mea waiwai kiʻekiʻe. ʻO ka hōʻoia maikaʻi kahi pane ikaika i ka hoʻokūkū ikaika mai nā mea ʻē aʻe. Eia naʻe, hōʻike ka noiʻi mākeke i ka ulu nāwaliwali o ka hoʻohana ʻana i nā mea hoʻohui lāʻau a me nā papahele lāʻau, ma ke kūkulu hou ʻana a i ka manawa e mālama ai i nā hiʻohiʻona lāʻau: ua hoʻololi pinepine ʻia ka puka lāʻau, puka aniani a papahele me kahi huahana mea ʻē aʻe ma mua o ka lāʻau.
ʻO ka ʻokoʻa, ʻo ka lāʻau ka mea kumu nui loa no nā lako, ʻoi aku ka nui o nā lako hale, a ʻaʻole i hoʻopilikia ʻia e ka hoʻokūkū mai nā huahana waiwai ʻē aʻe. Wahi a CSIL, ka hui noiʻi mākeke hale kūʻai mai Milan, ua helu ʻia ka lāʻau ma kahi o 74% o ka waiwai o ka hana hale ma EU28 i 2019, a ukali ʻia e ka metala (25%) a me ka plastic (1%).
Kuhi ʻia ka mākeke honua no nā uhi lāʻau ʻoihana e ulu ma 3.8% CAGR ma waena o 2022 a me 2027, me ka ulu ʻana o nā mea hana lāʻau e ulu wikiwiki ana ma 4% CAGR ma mua o nā uhi no ka hui ʻana (3.5%) a me ka papahele lāʻau (3%).
