Flame retardants Imiryango yimyenda
Flade retardants isanzwe yongewe kubicuruzwa byabaguzi kugirango byuzuze ibipimo byo gutwika ibikoresho byo mu nzu, imyenda, ibikoresho bya elegitoroniki, hamwe n’ibicuruzwa byubaka.
Imyenda irwanya umuriro irashobora kuba mubwoko bubiri: fibre naturel flame fibre cyangwa ivurwa hakoreshejwe imiti irwanya umuriro.Imyenda myinshi irashya cyane kandi irerekana impanuka yumuriro keretse iyo ivuwe hamwe na retardants.
Flade retardants ni itsinda ritandukanye ryimiti yongerwa cyane cyane mubicuruzwa byimyenda kugirango birinde cyangwa bidindiza ikwirakwizwa ryumuriro.Imiryango nyamukuru yumuriro wa flame ikunze gukoreshwa munganda zimyenda ni: 1. Halogens (Bromine na Chlorine);2. Fosifore;3. Azote;4. Fosifore na Azote
BFRs zikoreshwa mukurinda umuriro muri electronics nibikoresho byamashanyarazi.Kurugero mubirindiro bya tereviziyo na monitor ya mudasobwa, imbaho zicapye zumuzingo, insinga zamashanyarazi hamwe nifuro ya insulation.
Mu nganda z’imyenda BFRs zikoreshwa mu mwenda winyuma-utwikiriye imyenda, kwicara hamwe nibikoresho byo mu nzu.Ingero ni Polybromine diphenyl ethers (PBDEs) na biphenyls Polybromine (PBBs).
BFR ni ugukomera ku bidukikije kandi hari impungenge z’ingaruka iyi miti itera ubuzima rusange.Byinshi kandi byinshi BFR ntabwo yemerewe gukoreshwa.Muri 2023, ECHA yongereye ibicuruzwa bimwe kurutonde rwa SVHC, nka TBBPA (CAS 79-94-7), BTBPE (CAS 37853-59-1).
Iki cyiciro gikoreshwa cyane haba muri polymers no mumyenda ya selile.Mu bikoresho bya halogene bidafite umubiri wa halofosifore, cyane cyane fosifate ya triaryl (hamwe nimpeta eshatu za benzene zifatanije nitsinda ririmo fosifore) zikoreshwa nkuburyo bwo kuzimya umuriro.Organophosphorus flame retardants irashobora rimwe na rimwe kuba irimo bromine cyangwa chlorine.
Ibipimo byumutekano wibikinisho EN 71-9 birabuza ibintu bibiri byihariye bya fosifate flame retardants mubikoresho byimyenda byoroshye bikoreshwa mubikinisho bigenewe abana bari munsi yimyaka 3.Izi flame retardants zombi zishobora kuboneka mubikoresho by'imyenda bisubijwe inyuma na plastiki nka PVC kuruta imyenda y'imyenda ubwayo .. Tri-o-cresyl fosifate, fosifike ifite ubumara bwa tricresyl, ntabwo bishoboka cyane kugira yakoreshejwe kuruta tris (2-chloroethyl) fosifate.
Azote flame retardants ishingiye kuri melamine nziza cyangwa ibiyikomokaho, ni ukuvuga umunyu hamwe na acide organic cyangwa organique.Melamine isukuye nka flame retardant ikoreshwa cyane cyane mu gucana umuriro wa polyurethane yoroheje ifata ibikoresho byo mu nzu, imodoka / imyanya yimodoka hamwe nintebe zabana.Ibikomoka kuri Melamine nka FR bikoreshwa mubwubatsi no mubikoresho by'amashanyarazi na elegitoroniki.
Flame retardants yongeweho hagamijwe kuzamura umutekano wimyenda.
Menya neza ko wirinda ikintu icyo ari cyo cyose kibujijwe cyangwa kibujijwe.Muri 2023, ECHA yanditse Melamine (CAS 108-78-1) muri SVHC
Taifeng halogen yubusa ya flame retardants ishingiye kuri Fosifore na Nitrogen kumyenda & fibre.
Taifeng halogen idafite ibisubizo kumyenda na fibre bitanga umutekano wumuriro udateje ibyago bishya ukoresheje ibice byumurage bishobora guteza akaga.Ituro ryacu ririmo flame retardants yakozwe kugirango ikore fibre ya viscose / rayon hamwe nibikoresho bikora cyane mukurinda imyenda nimpu zubukorikori.Ku bijyanye nigitambara cyo gutwikira inyuma, kwitegura-gukoresha-gutatanya birashobora kurwanya umuriro na nyuma yo gukaraba no gukaraba byumye.
Kurinda umuriro udasanzwe, inyungu zingenzi zumuti wacu kumyenda na fibre.
Flame retardant Imyenda ikorwa na nyuma yo kuvura flame retardant.
flame-retardant imyenda yimyenda: flame retardant yigihe gito, igice cya kabiri cya flame retardant kandi kiramba (gihoraho) flame retardant.
Inzira yigihe gito ya retardant: koresha amazi-soluble flame retardant finans agent, nka ammonium polyphosphate yamazi, hanyuma ukayashyira kumurongo kumyenda uyibiza, padi, koza cyangwa utera, nibindi, kandi bizagira ingaruka zo gukumira umuriro nyuma yo gukama. .Irakwiriye Kubyubukungu kandi byoroshye gukemura ibintu bidakenewe kozwa cyangwa gukaraba gake, nkumwenda hamwe nizuba, ariko ntibishobora gukaraba.
Ukoresheje 10% -20% amazi ashonga APP igisubizo, TF-301, TF-303 byombi ok.Igisubizo cyamazi kirasobanutse kandi PH itabogamye.Ukurikije icyifuzo cyo kuzimya umuriro, umukiriya arashobora guhindura ibitekerezo.
Semi-burundu flame retardant process: Bivuze ko umwenda urangiye ushobora kwihanganira inshuro 10-15 zo gukaraba byoroheje kandi ugifite ingaruka zo kwirinda flame, ariko ntabwo irwanya isabune yo hejuru.Iyi nzira irakwiriye kumyenda yimbere yimbere, intebe yimodoka, gutwikira, nibindi.
TF-201 itanga ikiguzi-cyiza, kidafite halogene, fosifore ishingiye kumuriro utwikiriye imyenda no gutwikira.TF-201, TF- 201S, TF-211, TF-212 birakwiriye gutwikira imyenda.Semi-ihoraho ya flame retardant imyenda.Amahema yo hanze, amatapi, gupfuka urukuta, intebe zidindiza umuriro (imbere yimodoka, ubwato, gariyamoshi nindege) amagare yabana, ibitambara, imyenda ikingira.

| 35 | 63.7 | 0.25 | 0.05 | 1.0 |
Kurangiza flame-retardant kurangiza: Umubare wo gukaraba urashobora kugera inshuro zirenga 50, kandi ushobora gusabirwa.Irakwiriye imyenda yogejwe kenshi, nkimyenda ikingira akazi, imyenda yo kuzimya umuriro, amahema, imifuka, nibikoresho byo murugo.
Bitewe nimyenda ya flame-retardant nk'imyenda ya Oxford ya flame-retardant, ntabwo ishobora gutwikwa, ubushyuhe bwo hejuru, irinda ubushyuhe bwiza, nta gushonga, nta gutonyanga, n'imbaraga nyinshi.Kubwibyo, iki gicuruzwa gikoreshwa cyane munganda zubaka ubwato, gusudira ahahoze hubatswe ibyuma binini no gufata neza amashanyarazi, ibikoresho birinda gusudira gaze, inganda zikora imiti, metallurgie, theatre, amazu manini manini, supermarket, amahoteri nahandi hantu hahurira abantu benshi hamwe na hamwe guhumeka, gukumira umuriro n'ibikoresho byo gukingira.
TF-211, TF-212, nibyiza kumyenda iramba ya flame-retardant.Birakenewe kongeramo amazi.
Flame retardant ibipimo byimyenda mubihugu bitandukanye
Imyenda ya Flame-retardant yerekana imyenda ishobora guhita izimya mumasegonda 2 nyuma yo gusiga urumuri rufunguye nubwo rwakongejwe numuriro ufunguye.Ukurikije gahunda yo kongeramo ibikoresho bya flame retardant, hariho ubwoko bubiri bwimyenda ibanziriza kuvura flame-retardant hamwe nigitambara cya flame-retardant.Gukoresha imyenda ya flame-retardant irashobora gutinza neza ikwirakwizwa ryumuriro, cyane cyane gukoresha imyenda ya flame-retardant ahantu hahurira abantu benshi birashobora kwirinda guhitana abantu benshi.
Gukoresha imyenda ya flame-retardant irashobora gutinza neza ikwirakwizwa ryumuriro, cyane cyane gukoresha imyenda ya flame-retardant ahantu hahurira abantu benshi birashobora kwirinda guhitana abantu benshi.Ibisabwa byo gutwika imyenda mu gihugu cyanjye birasabwa cyane cyane kumyenda ikingira, imyenda ikoreshwa ahantu hahurira abantu benshi, ndetse n’imodoka imbere.
Imyenda yo mubwongereza flame retardant standard
1. BS7177 (BS5807) ibereye imyenda nk'ibikoresho byo mu nzu na matelas ahantu rusange mu Bwongereza.Ibisabwa byihariye kugirango imikorere yumuriro, uburyo bukomeye bwo gupima.Umuriro ugabanijwemo amasoko umunani y’umuriro kuva kuri 0 kugeza kuri 7, ahwanye n’inzego enye zo gukingira umuriro z’ibyago bito, biciriritse, birebire kandi byinshi cyane.
2. BS7175 ikwiranye nuburyo buhoraho bwo kurinda umuriro mumahoteri, ahakorerwa imyidagaduro nahandi hantu huzuye abantu.Ikizamini gisaba gutsinda ubwoko bubiri cyangwa bwinshi bwibizamini bya Gahunda4Igice1 na Gahunda5Igice1.
3. BS7176 ibereye ibikoresho bitwikiriye imyenda, bisaba kurwanya umuriro no kurwanya amazi.Mugihe cyikizamini, imyenda no kuzuza birasabwa kubahiriza Gahunda4Part1, Gahunda5Part1, ubucucike bwumwotsi, uburozi nibindi bipimo.Nuburyo bukomeye bwo kurinda umuriro kumyanya ya padi kurusha BS7175 (BS5852).
4. BS5452 ikoreshwa kumpapuro zo kuryama hamwe nimyenda y umusego ahantu rusange hahurira abantu benshi mubwongereza hamwe nibikoresho byose byatumijwe hanze.Birasabwa ko zishobora kuba zidafite umuriro nyuma yinshuro 50 zo gukaraba cyangwa gusukura byumye.
5.BS5438 ikurikirana: Pajama y'abana BS5722;Abongereza BS5815.3 ibitanda;Abongereza BS6249.1B umwenda.
Ikirangantego cyo muri Amerika Flame Retardant Standard
1. CA-117 ni uburyo bukoreshwa inshuro imwe yo gukingira umuriro muri Amerika.Ntabwo bisaba kwipimisha nyuma y’amazi kandi birakoreshwa kumyenda myinshi yoherezwa muri Amerika.
2. CS-191 nigipimo rusange cyo gukingira umuriro kumyenda ikingira muri Amerika, ishimangira imikorere yumuriro igihe kirekire no kwambara neza.Tekinoroji yo gutunganya muburyo busanzwe ni intambwe ebyiri zo guhuza cyangwa uburyo bwo guhuza intambwe nyinshi, bufite ibintu byinshi bya tekiniki kandi byongerewe agaciro kinyungu.
