ʻO nā mea hou i ka ʻenehana polyurethane (PU) pale ahi e hoʻololi hou i nā kūlana palekana waiwai ma waena o nā ʻoihana. Ke alakaʻi nei nā ʻoihana Kina me nā patent hou: Ua hoʻomohala ʻo Jushi Group i kahi nano-SiO₂-ehanced waterborne PU, e loaʻa ana i ka helu oxygen o 29% (Grade A fire resistance) ma o ka phosphorus-nitrogen synergy, ʻoiai ʻo Guangdong Yurong i hana i ka ternary intumescent flame retardant e hoʻopaʻa kemika me ka hoʻopaʻa ʻole ʻana i nā molekole PU lōʻihi. Ua hoʻohui ʻo Kunming Zhezitao i nā fila kalapona i hoʻololi ʻia i ka phosphate i loko o nā elastomers PU, e hoʻonui ana i ka paʻa wela a me ka hoʻokumu ʻana i ka char i ka wā o ka puhi ʻana.
I ka manawa like, holomua ka noiʻi honua i nā hoʻonā eco-friendly. Ua hōʻike ʻia kahi haʻawina ʻo 2025 ACS Sustainable Chemistry i nā ʻōnaehana phosphorus/silicona ʻole halogen e hiki ai i ka pale ʻana i ke ahi a me ka anti-dripping i loko o ka wai wai PU. ʻO ka nano-silica i loaʻa i ka husk i hui pū ʻia me nā mea hoʻopaneʻe halogen ʻole e hōʻike ana i ka ʻōlelo hoʻohiki no nā huʻa PU hoʻomau, e hoʻonui ana i nā pale wela me ka uahi ʻawaʻawa.
Ke alakaʻi ʻia nei e nā kānāwai palekana ahi-e like me EU REACH a me Kaleponi TB 117-ua manaʻo ʻia ka mākeke plastics flame-retardant e piʻi mai $3.5 biliona (2022) a i $5.2 biliona e 2030, me Asia-Pacific e hoʻomalu ana i ka 40% o ka noi honua. Hoʻokumu mua nā mea hou i ka palekana palekana, ka lōʻihi, a me ka hopena o ke kaiapuni, e hōʻailona ana i ka ulu hoʻololi no ke kūkulu ʻana, kaʻa, a me nā ʻāpana uila.
Ka manawa hoʻouna: Jul-03-2025
