ʻO ADCHEM FR-130 a me nā Masterbatches

ʻO Hexabromocyclododecane (HBCD), he mea hoʻohui i ka brominated flame retardant, ʻo ia kekahi o nā mea haumia kūlohelohe 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 ko 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 pūhui kūlohelohe i loaʻa i ka bromine i hoʻohana ʻia ma ke ʻano he ahi ahi i loko o ka ʻūhā insulation thermal 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 laʻana koko mai ʻumikūmākahi mau kuhina kaiapuni ʻEulopa a ʻekolu mau kuhina olakino, a ʻike ʻia ʻo HBCD i ke koko o kēlā me kēia o lākou.

ʻO ADCHEM FR-130 kekahi o nā mea pale ahi e pani ai 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 pani 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.

pae hoʻohui:

ʻO ka maʻamau 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.

Ke hana nei:

Manaʻo mākou i ke kaʻina hana ma lalo o 230 ° C.Pono e holoi ʻia ka extruder ma hope o ka pau ʻana o ka huʻa XPS e hoʻopau i ka lapalapa ahi.
