Cov ntaub tsis lees paub cov khoom ua ntej oxidized fiber ntau nrog kev kub siab ua haujlwm thiab aramid nrog lub zog zoo heev, pwm siab, kub tsis kam thiab hnav tsis kam, sib xyaw ua ke raws li qee qhov kev faib ua feem. kov yeej qhov tsis zoo ntawm ob lub fibers. Qhov zoo ntawm ob lub fibers yog coj los ua si.
Nplaim hluav taws xob qib: Qhov nyuaj ntawm qhov ntsuas no yog kev sib tw ntawm cov pa ua ntej cov pa oxygen thiab aramid. Cov khoom siv hluav taws xob hluav taws xob cov khoom siv hluav taws xob hluav taws xob cov khoom lag luam tom qab kev siv ntau dua, kev teeb tsa thiab thev naus laus zis tau hloov pauv zoo heev, yog li ntawd cov spinning tus nqi thiab cov xov paj zoo tau zoo tuaj, qhov spinning.aramid ntawv Hoobkastus nqi mus txog ntau dua 80%. Tom qab qhov cuam tshuam ntawm lub koom haum loj loj kev sim, cov ntsuas ntawm cov ntaub tau mus txog cov txheej txheem tsim nyog, tuaj yeem ua los ntawm kev kub siab, rwb thaiv tsev kub, nplaim hluav taws tiv thaiv khaub ncaws. Cov ntaub tsis tsuas yog muaj lub zog zoo, hnav tsis kam, thiab cov nplaim hluav taws zoo heev, kev kub siab ua haujlwm, thermal hluav taws xob tiv thaiv, tsuav yog tus nqi ntawm cov khoom lag luam ntawm tib hom 1113, muaj kev cia siab zoo rau kev ua haujlwm. Cov ntaub no tau raug pov thawj los ntawm cov neeg siv los ua tus thawj coj hauv kev muaj tiag, nyob rau hauv ib puag ncig ntawm UV tiv thaiv daim ntaub, hluav taws xob kub kub, kub melting tee, kub kub thiab lwm yam. Cov ntaub muaj qhov kub thiab txias tsis kam, rwb thaiv tsev kub, nplaim taws retardant multifunctional composite daim ntaub kev ua tau zoo, siab zog thiab ruaj khov dominance zog txo me ntsis.aramid ntawv Hoobkas
2 Feem ntau siv cov nplaim hluav taws kub hnyiab thiab hluav taws kub retardant daim ntaub pab cais tawm: ntau yam ntawm cov nplaim hluav taws kub, cov kev faib tawm kuj muaj ntau yam. Raws li cov nplaim retardant cov ntsiab lus, nws tuaj yeem muab faib ua halogenated nplaim retardant, phosphorus nplaim retardant, nitrogen nplaim retardant, thiab lwm yam. Raws li kev siv cov nplaim retardant thiab polymer nyob rau hauv daim ntawv, muab faib ua ntxiv hom thiab cov tshuaj tiv thaiv hom; Raws li lub durability ntawm nplaim retardant ntaub, nws muaj peev xwm muab faib ua peb hom: uas tsis yog-tawv nplaim retardant xov tus neeg saib xyuas, semi-kub nplaim retardant finishing tus neeg saib xyuas thiab check nplaim retardant xov. Raws li hom compound yuav muab faib ua inorganic nplaim retardant thiab organic nplaim retardant. Cov hauv qab no feem ntau qhia cov nplaim hluav taws ua haujlwm cov khaub ncaws uas tau faib los ntawm ob txoj hauv kev kawg.
1.1 Classification los ntawm durability ntawm fabricsaramid ntawv Hoobkas
1) Cov nplaim hluav taws uas tsis muaj hluav taws xob ua kom tiav: tseem hu ua nplaim hluav taws kub hnyiab ib ntus, feem ntau yog cov dej-soluble (los yog emulsion) inorganic ntsev. Cov nplaim hluav taws yog yaj hauv dej, thiab cov ntaub tuaj yeem siv tom qab dipping thiab ziab. Kuj tseem muaj ob chav da dej, chav da dej thib ob nrog ammonia lossis dej qab zib tshauv, kom cov oxide tso rau ntawm cov ntaub. Txoj kev no yog qhov yooj yim thiab pheej yig, tab sis qhov kev xav ntawm cov ntaub tsis zoo, thiab cov nplaim hluav taws kub hnyiab tau txo qis heev tom qab ntxuav. Nws yog feem ntau siv hauv cov khaub ncaws tiv thaiv pov tseg.
(2) Cov nplaim hluav taws kub hnyiab tau ua tiav: cov nplaim hluav taws kub hnyiab tau kho nrog cov txheej txheem no tuaj yeem maj mam ntxuav rau 1 ~ 10 zaug, tab sis tsis tiv taus kub xab npum ntxhua. Cov txheej txheem suav nrog urea phosphoric acid txoj kev (feem ntau hu ua Banflam method), urine phosphate method, ammonium phosphate - methyl acetate mixed solution method.
(3) Durability nplaim-retardant finishing tus neeg saib xyuas: Cov tshuaj yog siv rau polymerization los yog condensation nyob rau hauv lub sab hauv ntawm cov fiber ntau los ua dej-insoluble polymer, thiab cov tshuaj tiv thaiv feem ntau yuav tsum tau ntau tshaj 30 zaug. Cov txheej txheem tseem ceeb suav nrog Ciba (CP) txoj kev thiab Proban txoj kev. CP txheej txheem yog tsim los ntawm Ciba Company, Switzerland. Cov txheej txheem yog ib qho yooj yim rau kev siv thiab cov nplaim-retardant nyhuv yog zoo kawg li. Qhov tsis zoo yog tias lub zog poob ntawm cov ntaub yog loj dua thiab kev cuam tshuam ntawm kev ua haujlwm ntawm cov tsoos tsho loj dua. Proban txoj kev yog tsim los ntawm British Aubry Wilson Co., LTD., hom no tiav ntaub, nplaim retardant nyhuv yog zoo, tshwj xeeb tshaj yog tom qab kev kho mob ntawm cov ntaub thiab muaj zog tu yog incomparable rau lwm yam xov, tab sis txoj kev no yog heev txaus ntshai, hnyav ib puag ncig muaj kuab paug, yog li kev nce qib yog txwv.
2.2 Kev faib cov nplaim hluav taws xob los ntawm cov khoom sib xyaw
(1) Inorganic nplaim retardant: Inorganic nplaim retardant yog lub luag hauj lwm tseem ceeb ntawm kev nqus cua sov, lub ntsiab ntau yam muaj antibacterial deodorant ntaub aluminium hydroxide, magnesium hydroxide, liab phosphorus, antimony oxide, molybdenum oxide, ammonia molybdate, zinc borate, zinc oxide, zirconia. , zirconia, zirconia, thiab lwm yam, uas muaj aluminium hydroxide, magnesium hydroxide, liab phosphorus, antimony oxide yog siv dav tshaj plaws, tshwj xeeb tshaj yog aluminium hydroxide, magnesium hydroxide tuaj yeem ua tsis tau tsuas yog cov nplaim hluav taws kub hnyiab, tab sis kuj tuaj yeem ua si kom ua tiav. Lawv muaj cov yam ntxwv ntawm kev ruaj ntseg zoo, kev ua haujlwm siab, kev haus luam yeeb, drip resistance, kev nyab xeeb puv, yeej tsis muaj kuab paug rau ib puag ncig thiab pheej yig tus nqi, thiab lwm yam, thiab tau siv dav hauv cov khoom siv hluav taws xob tsis muaj hluav taws xob halogen. Tab sis inorganic nplaim taws retardant hluav taws retardant ntaub ntxhua khaub ncaws tsis zoo, qhov no yog vim inorganic nplaim retardant muaj zog polarity thiab hydrophilicity, thiab non-polar ntaub compatibility yog pluag. Nyob rau tib lub sijhawm, txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov nplaim hluav taws kub hnyiab, cov nplaim hluav taws kub hnyiab tau ntxiv rau ntau qhov, uas muaj kev cuam tshuam zoo rau cov khoom siv kho tshuab thiab cov khoom ua haujlwm ntawm cov ntaub ntawv. Yog li ntawd, nyob rau hauv xyoo tas los no, kev tshawb fawb ntawm superrefinement thiab nanization ntawm cov tsoos inorganic nplaim retardants tau txais kev saib tsis tau pom dua. Tsis tas li ntawd, txhawm rau txo cov nplaim hluav taws xob nrog tib cov nplaim hluav taws kub, nws tseem yog qhov kev tshawb fawb ntawm cov nplaim hluav taws kub nyhiab hauv xyoo tas los no los ua ke cov nplaim hluav taws kub hnyiab thiab kawm txog cov txiaj ntsig zoo ntawm cov nplaim hluav taws.
(2) Organic nplaim taws retardants: organic nplaim retardants muab faib ua phosphorus series thiab halogen series. Lub qub yog heev txwv nyob rau hauv nws siv. Halogenated nplaim retardants feem ntau suav nrog chlorine thiab bromine. Txawm li cas los xij, cov nyhuv ntawm cov tshuaj chlorine nplaim retardants yog qhov phem dua li bromine nplaim taws retardants, vim tias nws tsis yooj yim los tsim cov tshuaj dawb chlorine. Anti-wrinkle thiab non-ironing ntaub, ntxiv rau, vim corrosion thiab toxicity ntawm bromide tom qab thermal decomposition yog me me, yog li siv me me tuaj yeem ua tiav cov nplaim hluav taws kub zoo li chloride. Yog li brominated nplaim retardants muaj ntau ntau. Txawm li cas los xij, los ntawm qhov pom ntawm kev siv tag nrho, vim tias qhov tsis zoo ntawm cov nplaim hluav taws xob halogenated, uas muaj halogenated acid nyob rau hauv lawv cov khoom decomposition, cov pa luam yeeb loj thiab tsim kev puas tsuaj rau tib neeg lub cev, lawv maj mam hloov los ntawm lwm cov nplaim hluav taws tsis zoo thiab cov ntaub thaiv hluav taws. tshuaj ntxiv.
