ADCHEM FR-130 hamwe na Masterbatches

Hexabromocyclododecane (HBCD), inyongeramusaruro ya flame retardant, ni imwe mu myanda ihumanya kandi ikoreshwa cyane mu kubaka ibikoresho byo gukumira ku isi hose.HBCD izahagarikwa cyangwa ikurweho ku isi yose hakurikijwe amasezerano ya Stockholm yerekeye imyanda ihumanya ibidukikije.Umunyamakuru yize mu ishami ry’ibidukikije n’ibidukikije mu Ntara ku ya 1 Ugushyingo 2021 ko inganda 8 zitanga umusaruro mu gihugu hose zifite toni 28.000 za HBCD zose ziri mu ntara yacu.Mu mpera z'Ukwakira, imirongo y’umusaruro wa HBCD y’ibigo 8 bitanga umusaruro yarashenywe, kandi ibarura rya HBCD ryarahanaguwe.Hagati ya 2022, intara yacu ya Shandong izamenya ibikoresho byose, ibicuruzwa n’imyanda irimo HBCD kugeza kuri zeru rwose.

Ukuboza 2021, Ubushinwa bwahagaritse umusaruro, gukoresha, gutumiza mu mahanga no kohereza mu mahanga hexabromocyclododecane (HBCD), ikomatanyirizo ngengabuzima ririmo bromine ikoreshwa nk'urinda umuriro mu ifuro ry’ubushyuhe bwo hanze.

Kuva mu myaka ya za 1980, HBCD yakoreshejwe mu guteza imbere umuriro w’inyubako.Ariko, mu 2013, yashyizwe ku masezerano y’i Stockholm yerekeye imyanda ihumanya y’imyanda ihoraho kubera ko ifite ingaruka nyinshi ku buzima bw’abantu.Guhura na HBCD bigira ingaruka mbi kumikorere ya hormone, nervice na immunite.

HBCD yabonetse mu mwanda, mu mafi, mu kirere, amazi n'ubutaka.Icyamamare, mu 2004, Ikigega cy’isi cyita ku nyamaswa cyafashe urugero rw’amaraso kuri ba minisitiri w’ibidukikije 11 bo mu Burayi na minisitiri w’ubuzima batatu, maze basanga HBCD mu maraso ya buri wese muri bo.

ADCHEM FR-130 nimwe mubisimbuza flame retardant yo gusimbuza HBCD.Umubare wa Cas ni 97416-84-7.Ikoreshwa cyane cyane kuri EPS na XPS.Usibye ifu, turashobora gutanga ibishushanyo mbonera bya polystirene.Abakora XPS barashobora kuyikoresha gusa kugirango basimbuze HBCD.Kuberako stabilisateur yumuriro yamaze kongerwaho mubikorwa byacu bya FR.50% -40% FR ibishushanyo mbonera hamwe no gutatanya neza nuburyo bwo guhitamo.

Urwego rwongeyeho:

Mubisanzwe urugero: 1.5% - 5% kugirango ugere kuri DIN 4102 B1 kuri XPS.Biterwa kandi nuburyo bwimikorere nibisabwa byanyuma.

Gutunganya:

Turasaba ubushyuhe bwibikorwa biri munsi ya 230 ° C.Extruder igomba gukaraba nyuma yo kurangiza flame retardant urwego XPS ifuro.
