Ama-flame retardants Imindeni yezindwangu
Ama-flame retardants ngokuvamile angezwa emikhiqizweni yabathengi ukuze ahlangabezane nezindinganiso zokuvutha zefenisha, izindwangu, izinto zikagesi, nemikhiqizo yokwakha efana nokufaka izinto.
Izindwangu ezikwazi ukumelana nomlilo zingaba izinhlobo ezimbili: imicu yemvelo ekwazi ukumelana nelangabi noma ziphathwe ngekhemikhali ekwazi ukumelana nelangabi.Izindwangu eziningi zivutha kakhulu futhi ziletha ingozi yomlilo ngaphandle uma zelashwa ngama-flame retardants.
Ama-flame retardants yiqembu elihlukahlukene lamakhemikhali anezelwa ikakhulukazi emikhiqizweni yendwangu ukuvimbela noma ukubambezela ukubhebhetheka komlilo.Imindeni eyinhloko yama-flame retardants avame ukusetshenziswa embonini yendwangu yilena: 1. Ama-halogens (i-Bromine ne-Chlorine);2. Phosphorus;3. I-nitrogen;4. Phosphorus kanye Nitrogen
Ama-BFR asetshenziselwa ukuvimbela imililo kuma-electronics namathuluzi kagesi.Isibonelo ezindaweni ezivalekile zamasethi we-TV namamonitha ekhompuyutha, amabhodi esekethe aphrintiwe, izintambo zikagesi kanye namagwebu okushisa.
Embonini yezindwangu ama-BFR asetshenziswa kuma-back-coatings endwangu yamakhethini, indawo yokuhlala kanye nefenisha ekhuphukile.Izibonelo i-Polybrominated diphenyl ethers (PBDEs) kanye ne-Polybrominated biphenyls (PBBs).
Ama-BFR ayaphikelela emvelweni futhi kunokukhathazeka mayelana nezingozi ezibangelwa yila makhemikhali empilweni yomphakathi.I-BFR eyengeziwe ayivunyelwe ukuthi isetshenziswe.Ngo-2023, i-ECHA yenyusa eminye imikhiqizo ohlwini lwe-SVHC, njenge-TBBPA (CAS 79-94-7), BTBPE (CAS 37853-59-1).
Lesi sigaba sisetshenziswa kabanzi kokubili kuma-polymers kanye ne-textile cellulose fibers.Kuma-halogen-free organophosphorus flame retardants ikakhulukazi, ama-triaryl phosphates (enezindandatho ezintathu ze-benzene ezixhunywe eqenjini eliqukethe i-phosphorus) asetshenziswa njengezinye izindlela kunezinqamuleli ze-brominated flame.I-Organophosphorus retardants kwezinye izimo ingase ibe ne-bromine noma i-chlorine.
Izinga lokuphepha kwamathoyizi i-EN 71-9 linqabela izinciphisi zomlilo ze-phosphate eziqondile ezintweni ezifinyeleleka zendwangu ezisetshenziswa kumathoyizi ahloselwe izingane ezingaphansi kweminyaka emi-3 ubudala.Lezi zinto ezimbili ezibuyisela ilangabi kungenzeka zitholakale ezintweni zendwangu ezinamekwe emuva ngamapulasitiki afana ne-PVC kunendwangu yendwangu ngokwayo. I-Tri-o-cresyl phosphate, i-tricresyl phosphate enobuthi kakhulu, mancane kakhulu amathuba okuba nayo. isetshenziswe kune-tris (2-chloroethyl) phosphate.
I-nitrogen retardants yomlilo isekelwe ku-melamine emsulwa noma okuphuma kuyo, okungukuthi usawoti one-organic noma i-inorganic acid.I-melamine ehlanzekile njenge-flame retardant isetshenziselwa ikakhulukazi amagwebu e-polyurethane aguquguqukayo abuyisela ifenisha ezindlini, izihlalo zemoto/zezimoto kanye nezihlalo zezingane.Okuphuma ku-melamine njengama-FR asetshenziswa ekwakheni nasezinsizeni zikagesi neze-elekthronikhi.
Ama-flame retardants anezelwa ngenhloso ukuze kuthuthukiswe ukuphepha kwezindwangu.
Yenza isiqiniseko sokuthi ukugwema noma yiziphi izinqamuleli zomlilo ezikhawulelwe noma ezivinjelwe.Ngo-2023, i-ECHA yafaka kuhlu lwe-Melamine( CAS 108-78-1) ku-SVHC
I-Taifeng halogen retardants yamahhala ye-flame esekelwe ku-Phosphorus ne-Nitrogen yezindwangu nemicu.
Izixazululo ze-Taifeng halogen-free for textiles and fibers zinikeza ukuphepha emlilweni ngaphandle kokudala izingozi ezintsha ngokusebenzisa izinhlanganisela zefa eziyingozi.Umnikelo wethu uhlanganisa ama-flame retardants enziwe ngomthungi ukuze kukhiqizwe imicu ye-viscose/rayon kanye nezithako ezisebenza kahle kakhulu zokuvikela izindwangu kanye nesikhumba sokwenziwa.Uma kuziwa ezindwangu zokugqoka emuva, ukuhlakazeka okulungele ukusetshenziswa kungamelana nomlilo ngisho nangemva kwemijikelezo eminingi yokugeza nokuhlanza okomile.
Ukuvikelwa komlilo okubambekayo, izinzuzo ezibalulekile zesixazululo sethu sezindwangu nemicu.
Indwangu ye-flame retardant yenziwa nge-after-treatment flame retardant .
Ibanga lezindwangu ezinganqamuki amalangabi: i-retardant yesikhashana yomlilo, i-semi-permanent flame retardant kanye ne-dorable (unomphela) ye-flame retardant.
Inqubo yesikhashana yokunciphisa ilangabi: sebenzisa i-ejenti yokuqeda encibilika emanzini, efana ne-ammonium polyphosphate encibilika emanzini, futhi uyigcobe ngokulinganayo endwangu ngokucwilisa, ukugoqa, ukuxubha noma ukufutha, njll., futhi izoba nomthelela wokunqanda ilangabi ngemva kokoma. .Ifanelekile Ingokonga futhi kulula ukuyiphatha ezintweni ezingadingi ukuwashwa noma ukuwasha ngokungavamile, njengamakhethini nama-sunshades, kodwa aphikisana nokugeza.
Kusetshenziswa isisombululo se-APP esincibilikayo esingu-10% -20% , TF-301, TF-303 kokubili kulungile.Isixazululo samanzi sicacile futhi PH singathathi hlangothi .Ngokusho kwesicelo sokuvimbela umlilo, ikhasimende lingalungisa ukugxila.
Inqubo ye-Semi-permanent flame retardant: Kusho ukuthi indwangu eqediwe ingakwazi ukumelana nezikhathi ezingu-10-15 zokugeza okuthambile futhi isenomphumela wokunqanda ilangabi, kodwa ayimelani nensipho yokushisa ephezulu.Le nqubo ifanele indwangu yokuhlobisa ingaphakathi, izihlalo zemoto yemoto, izembozo, njll.
I-TF-201 ihlinzeka nge-flame retardant eyongayo, engeyona i-halogenated, esuselwe ku-phosphorus yezingubo zendwangu nokumboza.I-TF-201, TF- 201S , TF-211, TF-212 ifanele ukumbozwa kwendwangu.Indwangu engahlali unomphela ilangabi.Amatende angaphandle, okhaphethi, okumboziwe odongeni, izihlalo ezibamba ilangabi (ingaphakathi lezimoto, izikebhe, izitimela nezindiza) amakalishi ezingane, amakhethini, izingubo zokuzivikela.
