Tetrabromobisphenol A (TBBPA)

Terracore Chemicals ikambani inovimbwa nayo ye tetrabromobisphenol A inopa vagadziri vemabhodhi edunhu akadhindwa, ma compounder emagetsi, uye vagadziri vema polymer vane hunyanzvi. Tetrabromobisphenol A (TBBPA, CAS 79-94-7) ndiyo inonyanya kushandisa brominated flame retardant pasi rose, inoshandiswa zvakanyanya mumabasa e reactive uye additive. Iine bromine yakawanda inosvika 58.8%, inopa rimi retardancy inoshanda zvakanaka pamazinga akaderera ekutakura kupfuura dzimwe nzira dzakawanda.

Kushandisa TBBPA nenzira ye "reactivity" kana "additing"

Mukushandiswa kwayo kwakakosha, TBBPA inoshanda sechinhu chinodzivisa moto chinodzorwa mu epoxy-based printed circuit board (PCB) laminates. Mapoka ephenolic hydroxyl eTBBPA anoita zvakananga ne epoxy resin panguva yekupisa, achibatanidza bromine covalently mumusana wepolymer. Kubatanidzwa uku kunoderedza matambudziko ekufamba uye kubuda kwemvura uye kunoita kuti moto urambe uripo kwenguva refu unoramba uripo mukati mehupenyu hwechigadzirwa.

Mubasa rayo rekuwedzera, TBBPA inosanganiswa muABS, HIPS, uye polycarbonate compounds sechinowedzerawo chemuviri. Kuwanikwa kubva kune tetrabromobisphenol inoenderana. Mupi ane saizi yezvikamu zvakadzorwa uye kuchena kwakanyanya kwakakosha kuti awane kupararira kwakafanana uye kugona kudzokororwa kweUL94 V-0 muzvikamu zvemagetsi zvakagadzirwa.

Technical Magadzirirwo

TBBPA yakajairika kubva kuTerracore Chemicals: CAS 79-94-7; huremu hwemamorekuru 543.87 g/mol; huwandu hwebromine ~58.8%; kuchena (TBBPA) ≥99%; nzvimbo yekunyunguduka 178–182 °C; chitarisiko cheupfu huchena kusvika husina kuchena. Chitupa chekuongorora uye mushumo wekuyedzwa kwebromine zvinopihwa pese pakutumira.

Zvinyorwa zveMutemo uye zveKutevedzera Mutemo

TBBPA yakanyorwa seChinhu Chinonyanya Kunetsa (SVHC) paREACH Candidate List neECHA. Kushandiswa kwayo hakurambidzwi pasi peRoHS kana REACH Annex XIV, asi vanopinza nevanoisa zvinhu muEU vanofanirwa kutevedzera zvinodiwa neSVHC pakutaurirana nekuzivisa. Tinokurudzira kubvunza timu yenyu yezvemitemo musati mataura TBBPA muzvigadzirwa zvitsva zvemusika weEurope.

Kutsvaga & Kupa

Semutengesi we tetrabromobisphenol A zvakananga , Terracore Chemicals inoisa TBBPA mumabhegi emadziro akawanda ane 25 kg uye mabhegi makuru anorema 500 kg. Magwaro akazara - anosanganisira SDS, TDS, chitupa chekuongorora, uye mushumo wekuyedza bromine - anoperekedza zvese zvinotumirwa. Bata timu yedu yekutengesa kuti mukurukure nezvesarudzo yemagiredhi, nguva dzekutungamira, uye huwandu hushoma hweodha.

Kuchengeta uye Kubata

TBBPA inofanira kuchengetwa munzvimbo inotonhorera, yakaoma, ine mhepo inofefetera zvakanaka mupakeji yakavharwa zvakanaka, kure nezvinhu zvine oxidizing agents. Matanho akajairika ekudzora guruva anoshanda: kufefetera kwemhepo inobuda mumhepo, dziviriro yekufema yeP3, uye dziviriro yeganda nemaziso zvinokurudzirwa panguva yekubata. Bvunza SDS kuti uwane huwandu hwakazara hwemiganhu yekusvibiswa pabasa inoshanda munzvimbo yako.
