ADCHEM FR-130 ndi The Masterbatches

Hexabromocyclododecane (HBCD), chowonjezera cha brominated flame retardant, ndi chimodzi mwazinthu zomwe zimaipitsa zachilengedwe ndipo zimagwiritsidwa ntchito kwambiri pomanga zida zotchingira padziko lonse lapansi.HBCD idzaletsedwa kapena kuthetsedwa padziko lonse lapansi pansi pa Stockholm Convention on Persistent Organic Pollutants.Mtolankhaniyo adaphunzira kuchokera ku dipatimenti ya Provincial Ecology and Environment pa Novembara 1, 2021 kuti mabizinesi 8 opangira matani 28,000 a HBCD onse ali m'chigawo chathu.Pofika kumapeto kwa Okutobala, mizere yopangira HBCD ya mabizinesi 8 opangira idathetsedwa, ndipo mndandanda wa HBCD wachotsedwa.Pakati pa 2022, chigawo chathu cha Shandong chidzazindikira zida zonse, zopangira ndi zinyalala zomwe zili ndi HBCD mpaka ziro.

Mu Disembala 2021, China idathetsa kupanga, kugwiritsa ntchito, kutumiza ndi kutumiza kunja kwa hexabromocyclododecane (HBCD), gulu la organic lomwe lili ndi bromine lomwe limagwiritsidwa ntchito ngati chithovu chotsekereza lawi lakunja.

Kuyambira m'ma 1980, HBCD yakhala ikugwiritsidwa ntchito mobwerezabwereza kukonza chitetezo cha moto m'nyumba.Koma, mu 2013, adalembedwa mu Stockholm Convention on Persistent Organic Pollutants chifukwa cha chiopsezo chachikulu chomwe chimayambitsa thanzi la anthu.Kuwonetsedwa kwa HBCD kumakhala ndi zotsatirapo zoyipa pakugwira ntchito kwa mahomoni, manjenje ndi chitetezo chamthupi.

HBCD yapezeka mu zinyalala, nsomba, mpweya, madzi ndi nthaka.Chodziwika bwino, mu 2004, World Wildlife Fund inatenga zitsanzo za magazi kuchokera kwa nduna khumi ndi imodzi za chilengedwe ku Ulaya ndi nduna zitatu za zaumoyo, ndipo anapeza HBCD m'magazi a aliyense wa iwo.

1,1-(Isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene]

ADCHEM FR-130 ndi imodzi mwazolowa m'malo mwa flame retardant m'malo mwa HBCD.Nambala ya Cas ndi 97416-84-7.Amagwiritsidwa ntchito makamaka pa EPS ndi XPS.Kupatula ufa, titha kupereka masterbatches kwa polystyrene extruded.Opanga XPS amatha kugwiritsa ntchito kungosintha HBCD.Chifukwa matenthedwe okhazikika awonjezedwa kale mu FR masterbatches athu.50% -40% FR content masterbatches okhala ndi kubalalitsidwa bwinoko ndi zosankha.

Mulingo wowonjezera:

Nthawi zambiri mlingo: 1.5% - 5% kufika DIN 4102 B1 muyezo wa XPS.Zimatengeranso chikhalidwe cha ndondomeko ndi ntchito yomaliza.

Kukonza:

Timapereka kutentha kwa ndondomekoyi pansi pa 230 ° C.The extruder ayenera kutsukidwa akamaliza lawi retardant kalasi XPS thovu.
