Cov Tsev Neeg Tiv Thaiv Hluav Taws Kub rau Cov Ntaub
Cov tshuaj tiv thaiv hluav taws feem ntau raug ntxiv rau cov khoom siv rau cov neeg siv khoom kom ua tau raws li cov qauv kev kub hnyiab rau cov rooj tog, cov ntaub, cov khoom siv hluav taws xob, thiab cov khoom siv hauv tsev xws li kev rwb thaiv tsev.
Cov ntaub uas tiv taus hluav taws muaj ob hom: cov xov uas tiv taus hluav taws ntuj lossis siv cov tshuaj uas tiv taus hluav taws. Feem ntau cov ntaub yog cov uas kub hnyiab heev thiab muaj kev phom sij rau hluav taws tshwj tsis yog tias siv cov tshuaj tiv thaiv hluav taws.
Cov tshuaj tiv thaiv hluav taws yog ntau pawg tshuaj uas feem ntau ntxiv rau cov khoom siv textile kom tiv thaiv lossis ncua kev kis hluav taws. Cov tsev neeg tseem ceeb ntawm cov tshuaj tiv thaiv hluav taws uas feem ntau siv hauv kev lag luam textile yog: 1. Halogens (Bromine thiab Chlorine); 2. Phosphorus; 3. Nitrogen; 4. Phosphorus thiab Nitrogen
BFRs yog siv los tiv thaiv hluav taws hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Piv txwv li hauv cov thawv ntawm cov TV thiab cov saib xyuas computer, cov laug cam luam tawm, cov xov hluav taws xob thiab cov ua npuas rwb thaiv tsev.
Hauv kev lag luam textile, BFRs siv rau hauv cov ntaub txheej tom qab rau cov ntaub thaiv qhov rai, cov rooj zaum thiab cov rooj tog zaum. Piv txwv li Polybrominated diphenyl ethers (PBDEs) thiab Polybrominated biphenyls (PBBs).
BFRs yog cov tshuaj uas nyob ruaj khov hauv ib puag ncig thiab muaj kev txhawj xeeb txog cov kev pheej hmoo uas cov tshuaj no ua rau muaj kev noj qab haus huv rau pej xeem. Ntau thiab ntau BFR tsis raug tso cai siv. Xyoo 2023, ECHA tau nce qee cov khoom hauv daim ntawv teev npe ntawm SVHC, xws li TBBPA (CAS 79-94-7), BTBPE (CAS 37853-59-1).
Pawg no siv dav hauv cov polymers thiab textile cellulose fibers. Ntawm cov halogen-free organophosphorus flame retardants tshwj xeeb, triaryl phosphates (nrog peb lub nplhaib benzene txuas rau ib pawg phosphorus-muaj) yog siv los ua lwm txoj hauv kev rau brominated flame retardants. Organophosphorus flame retardants tej zaum yuav muaj bromine lossis chlorine nyob rau hauv qee kis.
Tus qauv kev nyab xeeb ntawm cov khoom ua si EN 71-9 txwv tsis pub siv ob hom tshuaj phosphate uas tiv thaiv hluav taws kub hauv cov ntaub ntawv textile uas siv rau cov khoom ua si rau cov menyuam yaus hnub nyoog qis dua 3 xyoos. Ob hom tshuaj no feem ntau pom muaj nyob rau hauv cov ntaub ntawv textile uas muaj cov yas xws li PVC txheej dua li cov ntaub textile nws tus kheej. Tri-o-cresyl phosphate, uas yog tricresyl phosphate lom tshaj plaws, tsis tshua muaj neeg siv dua li tris(2-chloroethyl) phosphate.
Cov tshuaj tua hluav taws nitrogen yog ua los ntawm melamine ntshiab lossis nws cov derivatives, piv txwv li ntsev nrog cov organic lossis inorganic acids. Melamine ntshiab ua cov tshuaj tua hluav taws feem ntau yog siv rau cov polyurethane ua npuas ncauj rau cov rooj tog zaum hauv tsev, lub rooj zaum tsheb / tsheb thiab lub rooj zaum menyuam yaus. Melamine derivatives ua FRs yog siv rau hauv kev tsim kho thiab hauv cov khoom siv hluav taws xob thiab hluav taws xob.
Cov tshuaj tiv thaiv hluav taws raug ntxiv rau lub hom phiaj los txhim kho kev nyab xeeb ntawm cov ntaub.
Xyuas kom tseeb tias kom tsis txhob muaj cov tshuaj tiv thaiv hluav taws uas txwv lossis txwv tsis pub siv. Xyoo 2023, ECHA teev Melamine (CAS 108-78-1) hauv SVHC
Taifeng cov tshuaj tua hluav taws uas tsis muaj halogen ua raws li Phosphorus thiab Nitrogen rau cov ntaub thiab cov fibers.
Cov kev daws teeb meem tsis muaj halogen rau cov ntaub thiab cov fibers ntawm Taifeng muab kev nyab xeeb hluav taws yam tsis tsim kev pheej hmoo tshiab los ntawm kev siv cov tshuaj lom neeg qub. Peb cov khoom muaj xws li cov tshuaj tiv thaiv hluav taws uas tsim tshwj xeeb rau kev tsim cov fibers viscose/rayon nrog rau cov khoom xyaw ua tau zoo rau kev tiv thaiv cov ntaub thiab tawv cuav. Thaum nws los txog rau cov ntaub txheej tom qab, cov tshuaj dispersion uas npaj txhij siv tau tuaj yeem tiv taus hluav taws txawm tias tom qab ntau zaus ntxuav thiab ntxuav qhuav.
Kev tiv thaiv hluav taws kub zoo, cov txiaj ntsig tseem ceeb ntawm peb cov kev daws teeb meem rau cov ntaub thiab cov fibers.
Cov ntaub thaiv hluav taws xob yog ua los ntawm kev kho mob tom qab.
qib ntaub nplaim taws: nplaim taws ib ntus, nplaim taws ib nrab mus tas li thiab nplaim taws ruaj khov (mus tas li).
Cov txheej txheem tiv thaiv hluav taws ib ntus: siv cov tshuaj tiv thaiv hluav taws uas yaj tau hauv dej, xws li ammonium polyphosphate uas yaj tau hauv dej, thiab thov kom sib npaug rau ntawm daim ntaub los ntawm kev dipping, padding, txhuam lossis txau, thiab lwm yam, thiab nws yuav muaj cov nyhuv tiv thaiv hluav taws tom qab ziab. Nws yog qhov tsim nyog rau Nws yog qhov pheej yig thiab yooj yim rau kev tuav ntawm cov khoom uas tsis tas yuav ntxuav lossis ntxuav tsis tu ncua, xws li cov ntaub thaiv qhov rai thiab cov ntaub thaiv hnub, tab sis nws tsis tiv taus kev ntxuav.
Siv 10% -20% cov dej soluble APP kua, TF-301, TF-303 ob qho tib si ok. Cov dej kua yog ntshiab thiab PH nruab nrab. Raws li qhov kev thov retardant hluav taws, cov neeg siv khoom tuaj yeem hloov kho qhov concentration.
Cov txheej txheem tiv thaiv hluav taws ib nrab mus tas li: Nws txhais tau tias cov ntaub tiav lawm tuaj yeem tiv taus 10-15 zaug ntawm kev ntxuav me me thiab tseem muaj cov nyhuv tiv thaiv hluav taws, tab sis nws tsis tiv taus kev ntxuav tes kub siab. Cov txheej txheem no yog qhov tsim nyog rau cov ntaub kho kom zoo nkauj sab hauv, lub rooj zaum tsheb, cov ntaub npog, thiab lwm yam.
TF-201 muab cov tshuaj tua hluav taws uas pheej yig, tsis muaj halogenated, phosphorus-based flame retardant rau cov txheej textile thiab cov ntaub npog. TF-201, TF-201S, TF-211, TF-212 yog cov tshuaj tua hluav taws semi-tas mus li rau cov ntaub npog. Cov tsev pheeb suab sab nraum zoov, cov ntaub pua plag, cov ntaub npog phab ntsa, cov rooj zaum tua hluav taws (sab hauv tsheb, nkoj, tsheb ciav hlau thiab dav hlau) cov tsheb thauj menyuam yaus, cov ntaub thaiv qhov rais, cov khaub ncaws tiv thaiv.
