I-ADCHEM FR-130 kunye ne-Masterbatches

I-Hexabromocyclododecane (HBCD), i-additive brominatedI-Flame Retardant, yenye yezinto ezizingisayo ezingcolisa indalo kwaye isetyenziswa kakhulu kwizixhobo zokwakha zokugquma kwihlabathi liphela. I-HBCD iya kuvalwa okanye ipheliswe kwihlabathi jikelele phantsi kweNgqungquthela yaseStockholm kwiZingcoliseko eziZingisayo zeOrganic. Intatheli ifunde kwiSebe lePhondo le-Ecology and Environment ngoNovemba 1, 2021 ukuba amashishini emveliso asi-8 kwilizwe lonke anomthamo weetoni ezingama-28,000 ze-HBCD onke akwiphondo lethu. Ekupheleni kuka-Okthobha, imizila yemveliso ye-HBCD yamashishini emveliso asi-8 iye yachithwa, kwaye uluhlu lwe-HBCD lususiwe. Embindini ka-2022, iphondo lethu laseShandong liya kuqonda zonke izinto, iimveliso kunye nenkunkuma equlethe i-HBCD ukuya kuthi ga kwiqanda ngokupheleleyo. NgoDisemba 2021, i-China yazisa isiphelo kwimveliso, ukusetyenziswa, ukungenisa kunye nokuthunyelwa ngaphandle kwe-hexabromocyclododecane (HBCD), i-organic compound equkethe i-bromine esetyenziswa njengeI-Flame Retardantkwi-foam yokufakelwa kwe-thermal yangaphandle. Ukususela ngo-1980, i-HBCD iqhele ukusetyenziswa ukuphucula ukhuseleko lomlilo wezakhiwo. Kodwa, ngo-2013, yadweliswa kwiNgqungquthela yaseStockholm kwiZingcoliseko eziZingisayo zeOganic ngenxa yokuba ibeka ingozi enkulu kwimpilo yabantu. Ukuvezwa kwi-HBCD kuneziphumo ezibi ezinokubakho ekusebenzeni kwehomoni, i-nervous kunye ne-immune system. I-HBCD ifunyenwe kwilindle, kwintlanzi, emoyeni, emanzini nasemhlabeni. Okudumileyo, ngo-2004, iWorld Wildlife Fund yathatha iisampulu zegazi kubaphathiswa bendalo abalishumi elinanye baseYurophu kunye nabaphathiswa abathathu bezempilo, kwaye yafumanisa i-HBCD egazini lakhe ngamnye kubo. 1,1-(Isopropylidene)bis[3,5-dibromo-4-(2,3-dibromo-2-methylpropoxy)benzene] ADCHEM FR-130 yenye indawoI-Flame Retardantendaweni ye-HBCD. Inombolo yeCas yi-97416-84-7. Isetyenziswa ikakhulu kwi-EPS kunye neXPS. Ngaphandle komgubo, sinokubonelela ngee-masterbatches ze-polystyrene ekhutshiweyo. Abavelisi beXPS banokuyisebenzisa ngokulula ukufaka endaweni ye-HBCD. Ngenxa yokuba i-thermal stabilizers sele yongezwe kwii-masterbatches zethu ze-FR. I-50% -40% ye-FR yomxholo we-masterbatches kunye ne-dispersion engcono zikhetho. Inqanaba elongezelelweyo: Ngokuqhelekileyo idosi: 1.5% - 5% ukufikelela kwi-DIN 4102 B1 umgangatho we-XPS. Kukwaxhomekeke kwimeko yenkqubo kunye nesicelo sokugqibela. Ukusetyenzwa: Sicebisa ubushushu benkqubo bungaphantsi kwama-230 °C. I-extruder kufuneka ihlanjwe emva kokugqibaI-Flame Retardantugwebu lweXPS yebakala.
