ʻO ADCHEM FR-130 a me nā Masterbatches

Hexabromocyclododecane (HBCD), he mea hoʻohui brominatedPaʻa ahi, ʻO ia kekahi o nā mea hoʻohaumia organik mau loa a hoʻohana nui ʻia i ke kūkulu ʻana i nā mea insulation a puni ka honua. E pāpā ʻia a hoʻopau ʻia ka HBCD ma ka honua holoʻokoʻa ma lalo o ka Stockholm Convention on Persistent Organic Pollutants. Ua aʻo ka mea kākau moʻolelo mai ka Provincial Department of Ecology and Environment ma Nowemapa 1, 2021 he 8 mau ʻoihana hana ma ka ʻāina me ka nui o 28,000 tons o HBCD aia ma kā mākou ʻāina. I ka hopena o ʻOkakopa, ua hoʻopau ʻia nā laina hana HBCD o nā ʻoihana hana 8, a ua hoʻomaʻemaʻe ʻia ka waihona HBCD. I ka waena o 2022, e ʻike ko mākou mokuʻāina ʻo Shandong i nā mea maka, nā huahana a me nā ʻōpala i loaʻa i ka HBCD i ka ʻole. I Kekemapa 2021, ua hoʻopau ʻo Kina i ka hana ʻana, hoʻohana, lawe mai a hoʻokuʻu aku i ka hexabromocyclododecane (HBCD), kahi mea hoʻohui i loko o ka bromine i hoʻohana ʻia ma ke ʻano he.Paʻa ahii loko o ka pahu hoʻoheheʻe wela waho. Mai ka makahiki 1980, ua hoʻohana mau ʻia ka HBCD e hoʻomaikaʻi i ka pale ahi o nā hale. Akā, i ka makahiki 2013, ua helu ʻia ia ma ka Stockholm Convention on Persistent Organic Pollutants no ka mea, ʻo ia ka pilikia nui o ke olakino kanaka. ʻO ka hoʻolaha ʻana iā HBCD he hopena koʻikoʻi paha i ka hana ʻana o ka hormone, hopohopo a me nā ʻōnaehana pale. Loaʻa ka HBCD i loko o ka lepo lepo, i ka iʻa, i ka ea, ka wai a me ka lepo. Kaulana, i ka makahiki 2004, ua lawe ka World Wildlife Fund i nā koko mai ʻumikūmākahi mau kuhina kaiapuni ʻEulopa a me ʻekolu mau kuhina olakino, a ʻike ʻia ʻo HBCD i ke koko o kēlā me kēia o lākou. 1,1-(Isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene] ʻO ADCHEM FR-130 kekahi o nā mea pani.Paʻa ahie pani i ka HBCD. ʻO ka helu Cas 97416-84-7. Hoʻohana nui ia no EPS a me XPS. Ma waho aʻe o ka pauka, hiki iā mākou ke hoʻolako i nā masterbatches no ka polystyrene extruded. Hiki i nā mea hana o XPS ke hoʻohana iā ia e hoʻololi i ka HBCD. No ka mea, ua hoʻohui ʻia ka thermal stabilizers i kā mākou masterbatches FR. ʻO 50% -40% FR content masterbatches me ka hoʻopuehu maikaʻi ʻia nā koho. Ka pae hoʻohui: ʻO ke ʻano maʻamau: 1.5% - 5% e hiki i ka maʻamau DIN 4102 B1 no XPS. Hoʻopili ia i ke kūlana kaʻina hana a me ka noi hope. Ka Hana ʻana: Manaʻo mākou i ka mahana o ke kaʻina hana ma lalo o 230 °C. Pono e holoi ʻia ka extruder ma hope o ka pau ʻana o kaPaʻa ahipahu XPS papa.
