No ka manawa lōʻihi, ua lanakila nā mea hana haole mai ʻAmelika Hui Pū ʻIa a me Iapana i ka mākeke pale ahi o ka honua me kā lākou pono i ka ʻenehana, kapikala a me nā ʻano huahana.Ua hoʻomaka ka ʻoihana pale ahi Kina i ka lohi a ke pāʻani nei i ke kuleana o ka hopu.Mai ka makahiki 2006, ua ulu wikiwiki ia.
I ka makahiki 2019, ʻo ka mākeke pale ahi honua ma kahi o 7.2 biliona USD, me ka hoʻomohala paʻa.Ua hōʻike ka ʻāina ʻo Asia Pākīpika i ka ulu wikiwiki loa.Ke neʻe mālie nei ka manaʻo ʻai i Asia, a ʻo ka piʻi nui mai ka mākeke Kina.I ka makahiki 2019, ua hoʻonui ʻia ka mākeke FR Kina e 7.7% i kēlā me kēia makahiki.Hoʻohana nui ʻia nā FR i ka uea a me ke kaula, nā mea pono hale, nā kaʻa a me nā kula ʻē aʻe.Me ka hoʻomohala ʻana o nā mea polymer a me ka hoʻonui ʻana i nā kahua noi, hoʻohana nui ʻia nā FR i nā ʻano like ʻole e like me nā mea hale kemika, nā mea uila, ka lawe ʻana, ka aerospace, nā lako, nā mea hoʻonaninani, nā lole, nā meaʻai, nā hale a me nā halihali.Ua lilo ia i ka lua o ka nui o ka polymer mea hoʻohui hoʻololi ma hope o ka plasticizer.
I nā makahiki i hala iho nei, ua hoʻoponopono mau ʻia a hoʻomaikaʻi ʻia ke ʻano hoʻohana ʻana o FRs ma Kina.Ua hōʻike ʻia ke koi o ka ultra-fine alumini hydroxide flame retardants i ka ulu wikiwiki ʻana, a ua emi mālie ka mākeke o nā mea hoʻopaʻa ahi halogen organik.Ma mua o 2006, ʻo nā FR home he mau mea hoʻopaʻa ahi halogen, a ʻo ka hoʻopuka ʻana o nā mea hoʻopaʻa ahi phosphorus inorganic a me organik (OPFRs) i helu ʻia no kahi hapa liʻiliʻi.I ka makahiki 2006, ʻo Kina ka ultra-fine alumini hydroxide (ATH) pale ahi a me ka magnesium hydroxide flame retardant i emi iho ma lalo o 10% o ka nui o ka ʻai.Ma 2019, ua piʻi nui kēia māhele.Ua hoʻololi mālie ke ʻano o ka mākeke pale ahi kūloko mai nā mea hoʻopaʻa ahi halogen organik i nā inorganic a me OPFRs, i hoʻohui ʻia e nā mea hoʻopaʻa ahi halogen organik.I kēia manawa, ʻo ka brominated flame retardants (BFRs) ka mea nui ma nā kahua noi he nui, akā ke wikiwiki nei ka phosphorus flame retardants (PFR) e pani i nā BFR ma muli o ka noʻonoʻo ʻana i ka mālama ʻana i ke kaiapuni.
Ma waho aʻe o 2017, ua hōʻike ʻia ka noi mākeke no nā mea pale ahi ma Kina i ka ulu mau a paʻa.I ka makahiki 2019, he 8.24 miliona tons ke koi o ka mākeke no nā ahi ahi, me ka piʻi ʻana o ka makahiki he 7.7%.Me ka hoʻomohala wikiwiki ʻana o nā mākeke noi i lalo (e like me nā mea pono hale a me nā lako hale) a me ka hoʻonui ʻana i ka ʻike pale ahi, e hoʻonui hou ʻia ka noi no nā FR.Ua manaʻo ʻia e 2025, ʻo ka noi no nā mea pale ahi ma Kina he 1.28 miliona tons, a ʻo ka ulu ʻana o ka hui mai 2019 a 2025 e manaʻo ʻia e hiki i 7.62%.
