I-ADCHEM FR-130 kanye ne-The Masterbatches

I-Hexabromocyclododecane (HBCD), i-additive brominated flame retardant, ingesinye sezingcolisi eziphilayo eziphikelelayo futhi isetshenziswa kabanzi ekwakheni izinto 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 zokusetshenziswa, imikhiqizo kanye nemfucuza 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-flame retardant kugwebu lwangaphandle lokufakwa okushisayo.

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.

I-ADCHEM FR-130 ingenye ye-flame retardant engena esikhundleni 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.

Ileveli yokwengeza:

Umthamo ojwayelekile: 1.5% - 5% ukuze ufinyelele izinga le-DIN 4102 B1 le-XPS.Kubuye kuncike esimweni senqubo kanye nesicelo sokugcina.

Iyacubungula:

Siphakamisa izinga lokushisa lenqubo libe ngaphansi kuka-230 °C.I-extruder kufanele igezwe ngemuva kokuqeda igwebu le-XPS lebanga le-flame retardant.
