ADCHEM FR-130 uye The Masterbatches

Hexabromocyclododecane (HBCD), a additive brominated flame retardant, ndeimwe yeanoramba achisvibisa organic uye anoshandiswa zvakanyanya mukuvaka zvivakwa zvekudzivirira pasi rese.HBCD icharambidzwa kana kubviswa pasi rose pasi peStockholm Convention on Persistent Organic Pollutants.Mutori wenhau akadzidza kubva kuProvincial Department of Ecology and Environment musi waMbudzi 1, 2021 kuti mabhizinesi masere ekugadzira munyika yose ane huwandu hwe28,000 matani eHBCD ese ari mudunhu redu.Pakupera kwaGumiguru, mitsara yekugadzira yeHBCD yemabhizinesi masere ekugadzira yakabviswa, uye hesiti yeHBCD yakabviswa.Pakati pa2022, purovhinzi yedu yeShandong ichaziva zvese zvekushandisa, zvigadzirwa uye tsvina ine HBCD kusvika zero zvachose.

Muna Zvita 2021, China yakamisa kugadzirwa, kushandisa, kuendesa kunze uye kutumira kunze kwenyika kwehexabromocyclododecane (HBCD), musanganiswa une bromine unoshandiswa semurazvo unodzoreredza mufuro rekunze rinopisa.

Kubva kuma1980, HBCD yagara ichishandiswa kuvandudza dziviriro yemoto yezvivakwa.Asi, muna 2013, yakanyorwa muStockholm Convention on Persistent Organic Pollutants nekuti ine njodzi huru yainoisa kuhutano hwevanhu.Kuratidzwa kuHBCD kune zvinogona kukanganisa mhedzisiro pakushanda kwehomoni, tsinga uye immune system.

HBCD yakawanikwa mutsvina yetsvina, muhove, mumhepo, mvura nevhu.Zvine mukurumbira, muna 2004, World Wildlife Fund yakatora ropa kubva kumakurukota gumi nerimwe ezvemamiriro ekunze emuEurope nemakurukota matatu ezvehutano, ndokuona HBCD muropa remumwe nemumwe wavo.

ADCHEM FR-130 ndeimwe yeanotsiva murazvo wemoto kutsiva HBCD.Nhamba yeCas ndeye 97416-84-7.Inonyanya kushandiswa EPS uye XPS.Kunze kwehupfu, tinogona kupa masterbatches eextruded polystyrene.Vagadziri veXPS vanogona kuishandisa kungotsiva HBCD.Nekuti thermal stabilizers akatowedzerwa mune yedu FR masterbatches.50% -40% FR zvemukati masterbatches ane kupararira kuri nani ndidzo sarudzo.

Kuwedzera level:

Kazhinji dosage: 1.5% - 5% kusvika kuDIN 4102 B1 chiyero cheXPS.Izvo zvinoenderanawo nemamiriro ekuita uye kushandiswa kwekupedzisira.

Kugadziridza:

Isu tinokurudzira tembiricha iri pasi pe230 ° C.Iyo extruder inofanirwa kugezwa mushure mekupedza murazvo wegiredhi retardant XPS foam.
