ADCHEM FR-130 thiab Masterbatches

Hexabromocyclododecane (HBCD), ib qho ntxiv brominated nplaim taws retardant, yog ib qho ntawm cov organic ua paug tsis zoo thiab tau siv dav hauv cov ntaub ntawv rwb thaiv tsev thoob plaws ntiaj teb.HBCD yuav raug txwv lossis tshem tawm thoob ntiaj teb raws li Stockholm Convention on Persistent Organic Pollutants.Tus neeg sau xov xwm tau kawm los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Noj Qab Haus Huv thiab Ib Cheeb Tsam Lub Kaum Ib Hlis 1, 2021 tias 8 lub tuam txhab tsim khoom thoob plaws lub tebchaws uas muaj peev xwm ntawm 28,000 tons ntawm HBCD yog tag nrho hauv peb lub xeev.Thaum kawg ntawm Lub Kaum Hli, HBCD cov kab ntau lawm ntawm 8 cov tuam txhab tsim khoom tau raug tshem tawm, thiab cov khoom lag luam HBCD tau raug tshem tawm.Nyob rau hauv nruab nrab ntawm 2022, peb lub xeev Shandong yuav paub tag nrho cov ntaub ntawv raw, khoom thiab pov tseg uas muaj HBCD mus rau xoom tag nrho.

Thaum Lub Kaum Ob Hlis 2021, Tuam Tshoj tau xaus rau kev tsim, siv, ntshuam thiab xa tawm ntawm hexabromocyclododecane (HBCD), cov organic compound uas muaj bromine siv los ua cov nplaim hluav taws kub nyhiab hauv cov thermal rwb thaiv tsev sab nraud.

Txij li xyoo 1980s, HBCD feem ntau tau siv los txhim kho kev tiv thaiv hluav taws ntawm cov tsev.Tab sis, hauv 2013, nws tau teev nyob rau hauv Stockholm Convention on Persistent Organic Pollutants vim nws muaj kev pheej hmoo siab nws ua rau tib neeg noj qab haus huv.Kev raug HBCD muaj peev xwm cuam tshuam rau kev ua haujlwm ntawm cov tshuaj hormones, lub paj hlwb thiab lub cev tsis muaj zog.

HBCD tau pom nyob rau hauv cov dej phwj tuaj, hauv cov ntses, hauv huab cua, dej thiab av.Muaj koob meej, xyoo 2004, World Wildlife Fund tau kuaj ntshav los ntawm kaum ib tus thawj coj hauv European ib puag ncig thiab peb tus kws saib xyuas kev noj qab haus huv, thiab kuaj pom HBCD hauv cov ntshav ntawm txhua tus ntawm lawv.

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

ADCHEM FR-130 yog ib qho ntawm cov hluav taws kub hloov pauv hloov HBCD.Cas: 97416-84-7.Nws yog tsuas yog siv rau EPS thiab XPS.Dhau li ntawm cov hmoov, peb tuaj yeem muab cov masterbatches rau extruded polystyrene.Cov tuam txhab ntawm XPS tuaj yeem siv nws yooj yim los hloov HBCD.Vim tias cov thermal stabilizers twb tau ntxiv rau hauv peb FR masterbatches.50% -40% FR cov ntsiab lus masterbatches nrog zoo dua dispersion yog cov kev xaiv.

Qib ntxiv:

Feem ntau noj: 1.5% - 5% kom ncav cuag DIN 4102 B1 tus qauv rau XPS.Nws kuj nyob ntawm tus txheej txheem txheej txheem thiab daim ntawv thov zaum kawg.

Kev ua:

Peb qhia cov txheej txheem kub hauv qab 230 ° C.Lub extruder yuav tsum tau ntxuav tom qab ua tiav cov nplaim hluav taws kub qib XPS ua npuas ncauj.
