Kawm txog nplaim taws-retardancing li Pa66 los ntawm liab phosphorus coated nrog cov resins sib txawv

Nylon 66 muaj cov khoom siv zoo, hnav tsis kam thiab tshuaj lom neeg tiv taus, thiab yog siv dav hauv kev kho tsheb, hauv hluav taws xob. Txawm li cas los xij, pa66 yog cov khoom siv hluav taws, thiab yuav muaj mob thaum hlawv, uas muaj kev nyab xeeb kev nyab xeeb. Yog li ntawd, nws yog qhov tseem ceeb tshaj plaws los kawm cov nplaim hluav taws xob rov qab hloov kho ntawm PA66. Cov nplaim taws retardant system ntawm PA66 siv los ua tus thawj coj los ntawm brominated nplaim retardants tau ntsib teeb meem kev tiv thaiv ib puag ncig thiab cti.

Ntawm tam sim no, liab phosphorus nplaim retardant tuaj yeem thov rau nplaim retardant pa66 cov ntaub ntawv vim nws cov nplaim taws siab retardant efficiency thiab kev ua tau zoo. Txawm li cas los xij, liab phosphorus nplaim taws retardants nyob rau hauv qhov siab kub, huab cua, siab av noo thiab nqus dej, ua rau cov khoom siv acidification. Cov phosphoric acid yuav croadode cov hlau Cheebtsam, ua rau cov khoom siv hluav taws xob ntawm cov khoom.

Txhawm rau tiv thaiv cov acidification ntawm cov tshuaj tiv thaiv liab phosphorus, los ntawm txoj hauv kev xim liab phosphorus, los ntawm kev sib tw liab posphorus, hauv phosphorization liab, nyob rau hauv lub phosphorization liab, nyob rau hauv lub phosphorization liab, nyob rau hauv lub phosphorization liab, nyob rau hauv lub posphorizor liab, hauv lub ntsej muag liab, hauv cov phosphorization xim liab Ua cov ntaub pua av ruaj khov, yog li koj tuaj yeem tiv thaiv nrog cov phosphorus liab thiab oxygen thiab dej acidification ntawm cov phosphorus liab, txhim kho kev ruaj ntseg ntawm kev siv cov khoom siv.

Txawm li cas los xij, cov txheej txheem sib txawv muaj cov kev sib txawv ntawm cov kab liab phosphorus nplaim retardant txhawb nqa nylon. Hauv qhov kev tshawb fawb no, ob lub ntsej muag liab liab uas muaj cov hluav taws xob ua ke ntawm cov khoom siv phebe pename

Qhov yooj yim muaj pes tsawg leeg ntawm cov khoom yog li hauv qab no: Melamine Resin Coated Red phosphorus nplaim redinet tswv (PF450): Liab phosphorus cov ntsiab lus ntawm 50%. Cov qauv tsim ntawm nplaim retardant Reinfant txhawb nqa nylon 66 yog 58% nylon 66, 12% nplaim taws retardant tswv khoom, 30% fiber ntau.

Coated liab phosphorus nplaim retardant enhanced pa66 cov ntawv formula

Tom qab blending thiab kev hloov kho, lub pa66 / gf30 composite coated nrog liab phosphorus nplaim retardant tau npaj, thiab cov khoom muaj feem tau ntsuas raws li hauv qab no.

1. Nplaim taws retardancy, kub hlau ntsuas kub thiab txheeb txheeb ze creepage cim cim

Nws tuaj yeem pom tau tias ob qho tib si pa66-1 # thiab pa66-2 # tuaj yeem ncav cuag cov nplaim retardant qib ntawm 1.6mm V-0, thiab cov ntaub ntawv tsis draw thaum lub sijhawm sib txuas. Ob yam ntawm coated liab phosphorus nplaim retardant enhanced pa66 muaj nplaim taws zoo retardant nyhuv. Lub glow-xaim-xaim-xaim hluav taws xob (GWFI) ntawm PA66-1 # thiab PA66-2 # tuaj yeem ncav cuag 960, thiab GWIT tuaj yeem ncav cuag 775 ℃. Qhov kev ntsuas ntsug ntawm kev ua yeeb yam thiab kev sim tshuaj pleev xim rau ob lub ntsej muag liab posphorus nplaim taws tuaj yeem ncav tau qib zoo heev.

Nws kuj tseem tuaj yeem pom tias PA66-1 me ntsis siab dua li CTI ntawm # PA66-2 #, thiab CTI ntawm ob qho yuav tsum muaj cov ntawv thov kev lag luam.

2. Cov cuab yeej kho tshuab

Cov cuab yeej kho tshuab yog qhov tseem ceeb ntawm cov nplaim hluav taws retardant rease txhawb nylon rau nws daim ntawv thov.

Nws tuaj yeem pom tau tias lub zog tensile thiab badend dages ntawm PA66-1 # yog siab dua, uas yog 164 MPA thiab 256 MPa siab dua, 5% siab dua li Pa66-1 #. Lub ntsiab lus cuam tshuam lub zog thiab tsis cuam tshuam dab tsi muaj zog ntawm pa66-1 # yog qhov siab dua, M2 thiab 21% siab dua li ntawm PA66-1 #, feem. Tag nrho cov khoom siv cov khoom siv ntawm ob yam khoom siv nrog cov phosphorus liab yog qhov siab, uas tuaj yeem ua tau raws li cov kev xav tau ntawm ntau thaj teb.

3. Tsos thiab tsw

Nws tuaj yeem pom los ntawm cov tsos ntawm ob hom kev txhaj tshuaj moulded cov qauv uas yog #) npaj nrog cov xim liab uas muaj cov xim liab, qaim xim thiab tsis muaj floating fiber ntawm Nto. Cov nplaim hluav taws ntawm cov nplaim hluav taws xob txhawb nqa pa66 (PA66-2 #) Npaj los ntawm phosphorus tsis muaj khaub ncaws thiab muaj ntau cov foilers floating. Qhov no yog tsuas yog vim Melamine Resin nws tus kheej yog cov hmoov zoo heev thiab cov khoom siv du, yog li cov khoom pom yog du, tsis muaj qhov pom tseeb ua ke fiber.

Ob hom liab phosphorus-coated nplaim retharaned enhanged pa66 tau muab tso rau ntawm 80 ℃ rau 2 teev, thiab lawv cov ntxhiab loj tau kuaj. PA66-1 # cov khoom siv tau pom tseeb ntxhiab thiab muaj ntxhiab tsw tsw ntxhiab tsw. PA66-2 # muaj ntxhiab tsw me me thiab tsis muaj pungent tsw ntxhiab. Qhov no yog feem ntau vim yog nyob rau hauv sitating coating txheej polymerization, cov amine coated resin me me molecules tsis yooj yim tshem tawm kom huv, thiab cov ntxhiab tsw ntawm cov khoom noj amine nws tus kheej yog qhov loj.

4. Dej ragentit

Vim tias Pa66 muaj cov pab pawg thiab cov pab pawg hydrogen, yog li nws yooj yim rau cov khoom siv dej, yog li nws yooj yim rau cov khoom siv dej, kom pom tseeb thiab pom tseeb hauv qab kev ntxhov siab.

Cawv ntawm cov nplaim taws sib txawv redrant liab phosphorus rau ntawm cov khoom nqus dej ntawm cov khoom siv tau kawm los ntawm kev sim cov dej nqus ntawm cov khoom siv. Nws tuaj yeem pom tias cov dej nqus dej ntawm ob cov ntaub ntawv nce nrog lub sijhawm nce. Qhov pib dej nqus ntawm PA66-1 # thiab PA62-2 # yog qhov zoo sib xws, tab sis nrog kev nqus dej nqus dej nqus ntawm cov khoom sib txawv yog obviously sib txawv. Ntawm lawv, Phenolico resin coated liab phosphorus nplaim retin (pa66-2 # me me me me Kev nqus tau tus nqi ntawm 6.4% tom qab 90 hnub. Qhov no feem ntau yog vim tias phenolic resin nws tus kheej dej nqus tus nqi yog tsawg, thiab cov dej khov kho yog qhov tsis zoo.

5. Corrosion tsis kam rau hlau

Los ntawm cov qauv khoob thiab rau cov khoom sib txawv liab phosphorus tshem tawm cov hlau corrosion hauv daim duab yuav tsawg dua, muaj ib qho huab cua me me thiab dej vapor corrosion tshwm sim los ntawm Cim, PA66-1 # ntawm cov hlau corrosion yog qhov zoo, cov hlau sib txawv yog qhov zoo dua, ob peb qhov loj tshaj plaws, thiab cov npoo ntawm cov hlau daim ntawv yog tarnished kiag li , thaum lub npoo ntawm daim ntawv tooj liab yog corroded thiab discolored obviously. Qhov no qhia tau hais tias cov corrosion ntawm Melamine Resin Coated Red Posphorous BRAME Retin Coated Red Posphorous Bame Red Beated Red Phosphorous Bame Redhat Nylon.

Hauv kev xaus, ob hom nplaim-retardant enhanced enhanced enhanced enhanced enhanced ating los ntawm txheej xim liab phosphorus nrog melamine cob thiab phenumed resin. Ob hom nplaim hluav taws-retardant tuaj yeem ncav cuag 1.6mmv-0, tuaj yeem dhau 775 ℃ Gleage-hlau hlau taws, thiab CTI tuaj yeem ncav cuag ntau dua 450V.

Lub zog tensile thiab Flexural zog ntawm PA66 tau txhim kho los ntawm Melamine Coated cov cuab yeej liab phosphorus, thaum cov khoom ntiag tug tau zoo dua los ntawm Phenolic Coated Liab phosphorus. Ib qho ntxiv, qhov tsis hnov ​​tsw ntawm phenolic resin coated nrog liab phosphorous enhanged pa66 yog tsawg dua li ntawm melamine cov khoom siv tau qis dua. Melamine cob qhia nrog liab phosphorous rede retharant txhim kho cov tsos ntawm pa66 nrog tsawg corrosion rau cov hlau.

Siv: Kev kawm ntawm cov nplaim hluav taws xob retardant thaj chaw ntawm pa66 coated nrog liab phosphorus, cov ntaub ntawv internet.
