I-ADCHEM FR-130 kanye ne-The Masterbatches

I-Hexabromocyclododecane (HBCD), isithasiselo se-brominatedI-Flame Retardant, ingenye yezinto ezingcolisa imvelo eziphikelelayo futhi isetshenziswa kabanzi ekwakheni ukufakwa kwezinto zokuvikela emhlabeni wonke. I-HBCD izovinjelwa noma isuswe emhlabeni jikelele ngaphansi kweNgqungquthela yaseStockholm Yokungcolisa Okuphilayo Okuqhubekayo. Intatheli ithole eMnyangweni Wezifundazwe wezeMvelo neMvelo ngoNovemba 1, 2021 ukuthi amabhizinisi angu-8 ezweni lonke anomthamo wamathani angu-28,000 e-HBCD wonke asesifundazweni sethu. Ekupheleni kuka-Okthoba, imigqa yokukhiqiza ye-HBCD yamabhizinisi angu-8 akhiqizayo isichithiwe, futhi uhlu lwamagama lwe-HBCD selusuliwe. Maphakathi no-2022, isifundazwe sethu sase-Shandong sizobona zonke izinto ezingavuthiwe, imikhiqizo kanye nemfucumfucu equkethe i-HBCD ibe ziro ngokuphelele. NgoZibandlela wezi-2021, i-China yaqeda ukukhiqizwa, ukusetshenziswa, ukungenisa nokuthekelisa ngaphandle kwe-hexabromocyclododecane (HBCD), isakhi se-organic esiqukethe i-bromine esetshenziswa njenge-I-Flame Retardantkugwebu lwangaphandle lokufakwa kwe-thermal. Kusukela ngawo-1980, i-HBCD ibivame ukusetshenziswa ukuthuthukisa ukuvikelwa komlilo kwezakhiwo. Kodwa, ngo-2013, yafakwa ohlwini lwe-Stockholm Convention on Persistent Organic Pollutants ngenxa yengozi enkulu ebeka ngayo empilweni yabantu. Ukuchayeka ku-HBCD kunemiphumela emibi engaba khona ekusebenzeni kwehomoni, izinzwa kanye namasosha omzimba. I-HBCD itholakale odongeni lwendle, ezinhlanzini, emoyeni, emanzini nasenhlabathini. Okudumile, ngo-2004, i-World Wildlife Fund yathatha amasampula egazi kongqongqoshe bezemvelo abayishumi nanye base-Europe kanye nongqongqoshe bezempilo abathathu, futhi yathola i-HBCD egazini lalowo nalowo kubo. 1,1-(Isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene] ADCHEM FR-130 ingenye ebambeleI-Flame Retardantesikhundleni se-HBCD. Inombolo ye-Cas ithi 97416-84-7. Isetshenziselwa ikakhulukazi i-EPS ne-XPS. Ngaphandle kwempushana, singahlinzeka ngama-masterbatches e-polystyrene ekhishwe. Abakhiqizi be-XPS bangayisebenzisa ukuze bangene esikhundleni se-HBCD. Ngoba izizinzisi ezishisayo sezivele zengeziwe kuma-masterbatches ethu e-FR. 50% -40% FR content masterbatches anokusabalalisa okungcono yizinketho. Izinga lokwengeza: Ngokuvamile umthamo: 1.5% - 5% ukuze ufinyelele izinga le-DIN 4102 B1 le-XPS. Kubuye kuncike esimweni senqubo kanye nesicelo sokugcina. Iyacubungula: Siphakamisa izinga lokushisa elingaphansi kuka-230 °C. I-extruder kufanele igezwe ngemuva kokuqedaI-Flame Retardantigwebu le-XPS.
