I-ADCHEM FR-130 kunye ne-Masterbatches

I-Hexabromocyclododecane (HBCD), i-additive brominated flame retardant, yenye yezinto ezizingisayo ezingcolisa indalo kwaye isetyenziswa ngokubanzi kwizixhobo zokwakha zokugquma kwihlabathi liphela.I-HBCD iya kuvalwa okanye ipheliswe kwihlabathi jikelele phantsi kweNgqungquthela yaseStockholm kwiZingcoliseko eziZingisayo zeOrganic.Intatheli ifunde kwiSebe lePhondo leEcology 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 nokuthumela ngaphandle kwe-hexabromocyclododecane (HBCD), i-organic compound equkethe i-bromine esetyenziswa njenge-flame retardant kwi-foam yangaphandle ye-thermal insulation.

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.

I-ADCHEM FR-130 yenye ye-substitute flame retardant ethatha indawo 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 lokongeza:

Ngokuqhelekileyo idosi: 1.5% - 5% ukufikelela kwi-DIN 4102 B1 umgangatho we-XPS.Kukwaxhomekeke kwimeko yenkqubo kunye nesicelo sokugqibela.

Iyaqhuba:

Sicebisa ubushushu benkqubo bungaphantsi kwama-230 °C.I-extruder kufuneka ihlanjwe emva kokugqiba i-flame retardant grade XPS foam.
