Kev tshawb fawb txog nplaim taws Retardancy ntawm Automotive Materials thiab Application Trends of Flame Retardant Fibers in Tsheb

Nrog rau kev loj hlob sai ntawm kev lag luam tsheb, tsheb-siv rau kev mus los lossis thauj khoom-tau dhau los ua cov cuab yeej tseem ceeb hauv tib neeg lub neej. Thaum lub tsheb muab kev yooj yim, lawv kuj ua rau muaj kev pheej hmoo ntawm kev nyab xeeb, xws li kev sib tsoo tsheb thiab kev sib tsoo tshwm sim. Vim yog qhov chaw kaw thiab cov khoom siv hluav taws xob sab hauv, ib zaug hluav taws tawg hauv lub tsheb, feem ntau nyuaj rau kev tswj, ua rau muaj kev phom sij rau lub neej thiab cov khoom ntawm cov neeg caij tsheb. Yog li ntawd, kev nyab xeeb hluav taws hauv tsheb yuav tsum yog ib qho kev txhawj xeeb loj rau cov neeg siv.

Ua rau lub tsheb hluav taws feem ntau tuaj yeem faib ua:
(1) Cov yam ntxwv ntawm lub tsheb, nrog rau cov teeb meem hluav taws xob, roj av, thiab kev sib txhuam ntawm cov khoom siv los ntawm kev hloov kho, kev teeb tsa, lossis kev saib xyuas tsis raug.
(2) Sab nraud yam, xws li kev sib tsoo, rollovers, arson, los yog qhov chaw uas tsis muaj ignition.

Cov tsheb fais fab tshiab, nruab nrog cov roj teeb uas muaj zog-qhov ceev, tshwj xeeb tshaj yog cov hluav taws kub nyhiab vim yog luv luv los ntawm kev sib tsoo, punctures, thermal runaway los ntawm qhov kub thiab txias, los yog ntau tshaj tam sim no thaum them ceev.

01 Kev Tshawb Fawb Txog Cov Hluav Taws Xob Retardancy ntawm Automotive Materials

Txoj kev kawm ntawm cov khoom siv hluav taws xob hluav taws xob tau pib thaum xyoo pua 19th hauv Tebchaws Meskas. Nrog rau kev nce qib hauv kev siv thev naus laus zis hauv xyoo tas los no, tau muaj kev xav tau tshiab rau kev tshawb fawb txog cov nplaim hluav taws xob ntawm cov khoom siv hauv tsheb, feem ntau hauv cov chaw hauv qab no:

Ua ntej, kev tshawb fawb theoretical ntawm nplaim retardancy. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb hauv Suav teb tau muab qhov tseem ceeb rau kev kawm txog kev sib xyaw ua ke ntawm ntau yam fibers thiab plastics, nrog rau kev siv cov nplaim hluav taws.

Thib ob, kev tsim cov khoom siv hluav taws xob retardant. Tam sim no, muaj ntau hom hluav taws kub retardant cov ntaub ntawv tab tom tsim. Thoob ntiaj teb, cov ntaub ntawv xws li PPS, carbon fiber, thiab iav fiber ntau tau ua tiav hauv ntau qhov kev lag luam.

Thib peb, kev tshawb fawb ntawm cov nplaim hluav taws kub nyhiab. Flame retardant fabrics yog ib qho yooj yim los tsim thiab ua tau zoo heev. Thaum nplaim hluav taws retardant paj rwb fabrics twb tau tsim zoo, kev tshawb fawb ntawm lwm cov nplaim hluav taws kub retardant textiles tseem txwv nyob rau hauv Suav teb.

Plaub, cov kev cai thiab kev sim cov khoom siv hluav taws xob.

Automotive tha xim sab hauv tuaj yeem muab faib ua peb pawg:

1. Cov khoom siv fiber ntau (piv txwv li, rooj zaum, ntaub pua plag, rooj zaum siv) - feem ntau siv thiab sib cuag ncaj qha nrog cov neeg caij tsheb.
2. Cov ntaub ntawv yas.
3. Cov khoom siv roj hmab.

Cov khoom siv fiber ntau, ua kom muaj hluav taws kub heev thiab nyob ze rau cov neeg caij tsheb, ua rau muaj kev pheej hmoo loj heev thaum hluav taws kub. Tsis tas li ntawd, qee cov khoom siv hauv tsheb, xws li cov roj teeb thiab cov cav, nyob ze ntawm cov ntaub ntawv textile, ua rau muaj kev sib kis ntawm hluav taws. Yog li ntawd, kev kawm txog cov nplaim hluav taws xob ntawm cov khoom siv hauv tsheb yog qhov tseem ceeb rau kev ncua sij hawm combustion thiab muab sijhawm khiav ntau dua rau cov neeg caij tsheb.

02 Kev faib tawm ntawm nplaim hluav taws xob fibers

Hauv cov ntawv thov kev lag luam textile, automotive textiles tuav ib qho tseem ceeb. Qhov nruab nrab neeg caij tsheb muaj kwv yees li 20-40 kg ntawm cov khoom siv sab hauv, feem ntau yog textiles, nrog rau lub rooj zaum, cushions, lub rooj zaum, thiab headrests. Cov ntaub ntawv no muaj feem xyuam nrog kev nyab xeeb ntawm cov neeg tsav tsheb thiab cov neeg caij tsheb, xav tau cov khoom siv hluav taws xob ua kom cov nplaim taws qeeb qeeb thiab nce lub sijhawm khiav tawm.

Nplaim retardant fiberstxhais tau tias yog cov fibers uas tsis tuaj yeem ignite lossis hlawv tsis tiav thaum sib cuag nrog qhov hluav taws kub, ua kom cov nplaim hluav taws tsawg thiab tua tus kheej sai sai thaum qhov hluav taws kub raug tshem tawm. Qhov Limiting Oxygen Index (LOI) feem ntau yog siv los ntsuas cov nplaim taws, nrog LOI siab tshaj 21% qhia tias tsis tshua muaj nplaim taws.

Nplaim retardant fibers tau muab faib ua ob pawg:

1. Inherently Nplaim Retardant Fibers
   Cov fibers no muaj cov pab pawg nplaim hluav taws nyob rau hauv lawv cov saw hlau polymer, txhim kho thermal stability, nce decomposition kub, suppressing flammable gas tiam, thiab txhawb char tsim. Piv txwv li:

• Aramid fibers (piv txwv li, para-aramid, meta-aramid)
• Polyimide fibers (piv txwv li, Kermel, P84)
• Polyphenylene sulfide (PPS) fiber ntau
• Polybenzimidazole (PBI) fiber ntau
• Melamine fibers (piv txwv li, Basofil)

Meta-aramid, polysulfonamide, polyimide, thiab PPS fibers twb tau tsim nyob rau hauv Suav teb.

1. Hloov cov nplaim hluav taws kub retardant fibers
   Cov fibers no tau txais cov nplaim hluav taws kub nyhiab los ntawm cov khoom siv ntxiv lossis kev kho saum npoo, suav nrog:

• Nplaim retardant polyester
• Nplaim retardant nylon
• Nplaim retardant viscose
• Nplaim retardant polypropylene

Cov kev hloov kho muaj xws li copolymerization, blending, composite spinning, grafting, thiab post-finishing.

03 Daim Ntawv Thov Kev Ua Haujlwm Siab Nplaim Retardant Fibers hauv Kev Tiv Thaiv Tsheb

Automotive nplaim retardant cov ntaub ntawv yuav tsum tau raws li cov kev cai tshwj xeeb vim qhov chaw txwv. Tsis zoo li lwm yam kev siv, cov ntaub ntawv no yuav tsum tiv thaiv hluav taws los yog muaj kev tswj xyuas qhov kub hnyiab (piv txwv li, ≤70 mm / min rau cov neeg caij tsheb).

Tsis tas li ntawd, cov kev xav tau suav nrog:

• Cov pa luam yeeb tsawg tsawg thiab cov pa roj carbon monoxide tsawg tsawgkom muaj kev nyab xeeb rau neeg caij tsheb.
• Anti-static zogtiv thaiv hluav taws los ntawm roj vapor lossis plua plav .

Cov ntaub ntawv pov thawj qhia tias txhua lub tsheb siv 20-42 m² ntawm cov ntaub ntawv textile, qhia tias muaj peev xwm loj hlob nyob rau hauv tsheb textiles. Cov ntaub ntawv no tau muab faib ua hom kev ua haujlwm thiab kho kom zoo nkauj, nrog rau kev nce ntxiv ntawm kev ua haujlwm-tshwj xeeb yog nplaim hluav taws-vim muaj kev txhawj xeeb txog kev nyab xeeb.

High-performance nplaim retardant textiles yog siv nyob rau hauv:

• Lub rooj zaum npog
• Qhov rooj panels
• Cov log tsheb
• Airbags
• Cov ntaub pua tsev
• Soundproofing thiab rwb thaiv tsev cov ntaub ntawv

Non-woven fabrics ua los ntawm polyester, carbon fiber, polypropylene, thiab iav fiber ntau kuj siv dav hauv tsheb sab hauv.

Txhawb cov nplaim hluav taws kub hnyiab hauv tsheb tsis yog tsuas yog txhim kho kev nyab xeeb ntawm cov neeg caij tsheb tab sis kuj tseem ua rau muaj kev noj qab haus huv hauv zej zog.
