Flame retardants Mhuri dzemicheka
Flame retardants inowanzowedzerwa kune zvigadzirwa zvevatengi kuti zvisangane nekupisa zviyero zvefenicha, machira, zvemagetsi, uye zvigadzirwa zvekuvaka senge insulation.
Machira asingadziviriri pamoto anogona kunge ari emhando mbiri: echisikigo asingadziviriri faibha kana kurapwa nekemikari inodzivirira moto.Machira mazhinji anopisa zvakanyanya uye anopa njodzi yemoto kunze kwekunge akarapwa nemishonga inodzoreredza moto.
Flame retardants iboka rakasiyana remakemikari anowedzerwa zvakanyanya kune zvigadzirwa zvemachira kudzivirira kana kunonoka kupararira kwemoto.Mhuri huru dzemafuta anodzosa moto ayo anowanzo shandiswa muindasitiri yemachira ndeaya: 1. Halogens (Bromine neChlorine);2. Phosphorus;3. Nitrogen;4. Phosphorus uye Nitrogen
MaBFR anoshandiswa kudzivirira moto mumagetsi nemidziyo yemagetsi.Semuenzaniso mune zvakavharirwa zveTV seti uye mamonitor emakombuta, akadhindwa edunhu mabhodhi, tambo dzemagetsi uye mafuro ekudzivirira.
Muindasitiri yemachira BFRs anoshandiswa mumucheka kumashure-machira emaketeni, zvigaro uye upholstered fenicha.Mienzaniso iPolybrominated diphenyl ethers (PBDEs) uye Polybrominated biphenyls (PBBs).
BFR's kushingirira munharaunda uye pane kushushikana nezve njodzi idzi makemikari dzinounza kuhutano hweveruzhinji.Yakawanda uye yakawanda BFR haibvumidzwe kushandiswa.Muna 2023, ECHA yakawedzera zvimwe zvigadzirwa muhurongwa hweSVHC, zvakaita seTBBPA (CAS 79-94-7), BTBPE (CAS 37853-59-1).
Ichi chikamu chinoshandiswa zvakanyanya mumapolymers uye textile cellulose fibers.Pakati pehalogen-isina organophosphorus flame retardants kunyanya, triaryl phosphates (ine mhete nhatu dzebenzene dzakabatanidzwa neboka rine phosphorus) dzinoshandiswa sedzimwe nzira dzebrominated flame retardants.Organophosphorus flame retardants mune dzimwe nguva inogona kunge iine bromine kana chlorine.
EN 71-9 chiyero chekuchengetedza chitoyi chinorambidza maviri chaiwo phosphate murazvo retardants mune anowanikwa machira anoshandiswa mumatoyi akagadzirirwa vana vari pasi pemakore matatu ezera.Izvi zviviri zvinodzoreredza moto zvinowanzowanikwa mumicheka yakavharwa nepurasitiki sePVC pane jira remachira pacharo. yakashandiswa kupfuura tris (2-chloroethyl) phosphate.
Nitrogen flame retardants inobva pa pure melamine kana zvinobva pairi, kureva munyu une organic kana inorganic acids.Yakachena melamine senge inodzoreredza murazvo inonyanya kushandiswa kudzoreredza murazvo wepolyurethane anochinjika furo dzefenicha yakasimudzwa mudzimba, zvigaro zvemotokari/motokari uye zvigaro zvevana.Melamine derivatives seFRs inoshandiswa mukuvaka uye mumagetsi nemagetsi emidziyo.
Flame retardants inowedzerwa nechinangwa kuvandudza kuchengetedzwa kwemachira.
Ita shuwa kuti udzivise chero zvinorambidzwa kana kurambidzwa zvinodzoreredza moto.Muna 2023, ECHA yakaronga Melamine ( CAS 108-78-1) muSVHC
Taifeng halogen yemahara murazvo retardants yakavakirwa paPhosphorus uye Nitrogen yemachira & fiber.
Taifeng halogen-yemahara mhinduro dzemachira uye faibha inopa chengetedzo pamoto pasina kugadzira njodzi nyowani nekushandisa zvine ngozi zvinosanganisirwa nhaka.Chipo chedu chinosanganisira zvinogadziridza-zvakagadzirwa nemoto zvinodzoreredza kugadzirwa kweviscose / rayon fibers pamwe nepamusoro-soro zvigadzirwa zvekudzivirira machira nematehwe ekugadzira.Kana zvasvika kune machira ekudzokera kumashure, kugadzirira-kushandisa-kupararira kunogona kuramba moto kunyangwe mushure mekugezesa kwakawanda uye kuoma-kuchenesa.
Kudzivirirwa kwemoto kunobatika, mabhenefiti akakosha emhinduro yedu yemachira uye fiber.
Flame retardant Textile inogadzirwa mushure mekurapa moto unodzoreredza.
flame-retardant textile giredhi: temporary flame retardant, semi-permanent flame retardant uye yakasimba (permanent) flame retardant.
Kwenguva pfupi murazvo unodzoreredza maitiro: shandisa mvura-inonyungudika murazvo wemoto unodzoreredza, senge mvura-inonyungudika ammonium polyphosphate, woiisa zvakaenzanirana pajira nekunyudza, padding, kubhurasha kana kupfapfaidza, zvichingodaro, uye ichave nemoto unodzoreredza mhedzisiro mushure mekuoma. .Inokodzera Iyo ine hupfumi uye iri nyore kubata pane zvinhu zvisingadi kushambidzwa kana kushambidzwa zvisingaite, semaketeni uye sunshades, asi haipokana nekugeza.
Kushandisa 10% -20% mvura soluble APP mhinduro, TF-301, TF-303 zvose zvakanaka.Mhinduro yemvura yakajeka uye PH isina kwayakarerekera.Zvinoenderana nechikumbiro chekudzivirira moto, mutengi anogona kugadzirisa iyo yekumisikidza.
Semi-permanent flame retardant process: Zvinoreva kuti jira rakapedzwa rinogona kumira 10-15 nguva yekuwachisa zvinyoro uye richiri nemoto unodzoreredza mhedzisiro, asi haimiri kune yakanyanya kupisa sipo.Iyi maitiro akakodzera mukati mekushongedza jira, mota zvigaro zvemota, zvekuvharira, nezvimwe.
TF-201 inopa inodhura-inoshanda, isiri-halogenated, phosphorus-based flame retardant yemachira machira uye zvekufukidzira.TF-201, TF- 201S , TF-211, TF-212 vakakodzera kupfeka machira.Semi-permanent flame retardant textile.Matende ekunze, makapeti, zvifukidziro zvemudhuri, zvigaro zvinodzivirira moto (mukati memotokari, mabhoti, zvitima nendege) zvingoro zvevana, maketeni, zvipfeko zvinodzivirira.
