Pre-Oxygenated Filament Spunlace Nonwoven Fabrics

1. Cov txiaj ntsig tseem ceeb ntawm cov ntaub nonwoven uas tau ua ntej oxidized: Kev ua tau zoo hauv kev ua tau zoo ntawm cov fiber tshwj xeeb

Cov ntaub tsis-woven uas tau ua ntej oxidized yog ua los ntawm "carbon fiber precursor pre-oxidized fibers", sib xyaw cov yam ntxwv ntawm spunlace yam tsis muaj cov nplaum txhawb nqa. Nws ua tiav qhov zoo dua li cov ntaub tsis-woven ib txwm muaj hauv kev hloov pauv ib puag ncig, kev ruaj khov tshuaj lom neeg, thiab kev ua haujlwm ntawm cov qauv. Cov txiaj ntsig tseem ceeb tau pom hauv tsib qhov ntev:

1. Kev tiv thaiv kub heev thiab nplaim taws retardancy, kev nyab xeeb ib puag ncig hnyav heev

Kev tiv thaiv kub zoo heev: Cov fibers pre-oxidized raug kho tshwj xeeb oxidation los ua ib feem ntawm cov qauv ringed, uas tuaj yeem ua haujlwm ruaj khov ntawm 220 ° C rau lub sijhawm ntev. Lub zog khaws cia tus nqi yog 100% thaum siv tas li ntawm 240 ° C, pib maj mam decompose ntawm 370 ° C, thiab pib carbonize tab sis tsis yaj ntawm 400 ° C, daws tag nrho cov teeb meem ntawm kev yaj kub ntawm cov tshuaj fiber nonwoven ntaub thiab hlawv ntawm paj rwb nonwoven ntaub.

Kev tua hluav taws uas tua tau tus kheej yam tsis muaj dej ntws: Nws muaj cov yam ntxwv tua tau tus kheej ntuj. Thaum raug hluav taws, nws tsuas yog carbonizes thiab tsis hlawv. Thaum lub sijhawm hlawv, tsis muaj qhov ntsws lossis yaj poob. Cov nplaim taws tua tam sim ntawd tom qab tshem tawm cov nplaim taws, nrog rau kev tua hluav taws ncav cuag GB 8624-2012 A-level tus qauv, zoo thaiv kev sib kis ntawm cov nplaim taws thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv.

2. Kev tiv thaiv xeb tshuaj lom neeg puv ntoob, muaj zog hloov pauv mus rau cov xov xwm hnyav

Kev tiv thaiv xeb dav dav yam tsis muaj ces kaum tuag: Nws muaj kev kam rau cov kua qaub muaj zog (xws li 98% sulfuric acid), cov hauv paus muaj zog (xws li 40% sodium hydroxide kua), thiab ntau yam organic solvents (ethanol, acetone, roj cav, thiab lwm yam). Qhov poob ntawm lub zog tawg tom qab soaking rau 72 teev yog ≤5%, zoo dua li cov ntaub polyester tsis-woven (qhov poob feem ntau> 30%).

Kev ruaj khov ib puag ncig: Nyob rau hauv qhov av noo siab (av noo txheeb ze 95%), tshuaj tsuag ntsev ntau (ib puag ncig ntug dej hiav txwv), thiab cov xwm txheej ua qias tuaj ntawm kev lag luam, tsis muaj pwm, xeb, lossis kev ua haujlwm poob qis. Lub neej ua haujlwm yog 3-5 npaug ntawm cov ntaub tsis-woven uas yog cov tshuaj fiber ntau, tsim nyog rau kev siv sab nraum zoov thiab kev lag luam mus sij hawm ntev.

3. Kev sib npaug ntawm cov qauv kho tshuab, kev ua haujlwm ruaj khov hauv ob qho tib si qhuav thiab ntub dej

Lub zog spunlace zoo heev: Siv 4 txoj kev ua haujlwm spunlace uas tsis muaj zog heev, qhov ceev ntawm cov fiber spunlace yog siab dua 25% piv rau cov txheej txheem ntawm koob punch. Lub zog tawg ntev yog ≥20N / 5cm, lub zog tawg transverse yog ≥15N / 5cm, thiab qhov ceev ntawm lub zog ntub dej yog siab dua 95%. Tsis muaj kev poob lossis kev puas tsuaj tom qab rov ua dua thiab sib txhuam.

Kev ruaj khov ntawm qhov ntev: Tom qab kev kho mob ua ntej thiab kho qhov kub siab, qhov sib txawv ntawm qhov ntev yog ≤1% hauv qhov kub ntawm -40 ° C txog 200 ° C, qis dua li ntawm cov ntaub tsis-woven ib txwm muaj (feem ntau 3% -5%), uas tuaj yeem tswj tau qhov zoo ntawm cov duab ntev thiab tsim nyog rau cov xwm txheej nrog cov kev xav tau siab xws li kev kaw cov khoom siv precision thiab cov khaub ncaws tiv thaiv tshwj xeeb.

4. Kev sib raug zoo muaj zog, kev hloov kho ntau yam thiab kev hloov kho

Kev ua haujlwm dav dav: Txhawb ntau yam kev hloov kho cov qauv xws li cov ntaub sib xyaw ua ke, cov qauv mesh ntom ntom, thiab cov qauv qhov gradient. Qhov kev npog ib square meter yog 50-300g, thiab nws tuaj yeem ua tiav los ntawm kev txiav, sib xyaw, txheej, thiab lwm yam, nrog rau qhov poob ntawm <1.5%, haum rau ntau yam kev xav tau xws li kev tiv thaiv yooj ywm mus rau kev sib khi ruaj khov. Kev Ua Haujlwm Sib Tov Tsis Muaj Kev Tsis Sib Haum: Raws li kev khaws cia qhov kev ua tau zoo thawj, ntau yam modules ua haujlwm xws li txheej tiv thaiv hluav taws, txheej conductive, thiab txheej adsorption tuaj yeem ua ke. Piv txwv li, tom qab ntxiv txheej graphite, electromagnetic shielding tuaj yeem ua tiav; los ntawm kev ntxiv cov pa roj carbon activated, cov pa roj tawm tuaj yeem txhim kho, thiab kev ua haujlwm tseem ceeb ntawm kev tiv taus kub thiab nplaim taws retardancy yuav tsis raug cuam tshuam.

5. Kev tiv thaiv ib puag ncig thiab kev nyab xeeb hauv kev sib npaug, tswj tau thoob plaws hauv lub voj voog ntawm lub neej

Cov txheej txheem tsim khoom huv si: Siv cov kab ntau lawm uas kaw tag nrho thiab huv si, cov txheej txheem koob tsuas yog siv dej thiab hluav taws xob xwb. Los ntawm lub tshuab lim dej, tus nqi rov siv dej dua txog 90%, tsis muaj pa roj pov tseg lossis cov khib nyiab pov tseg, thiab nws ua raws li cov qauv tsim khoom tiv thaiv ib puag ncig.

Kev Pov Tseg Cov Khib Nyhiab Kom Muaj Kev Nyab Xeeb: Tom qab pov tseg, nws tuaj yeem hloov mus ua cov pa roj carbon inorganic los ntawm kev ua kom kub siab, yam tsis tso cov pa phem, lossis rov ua dua tshiab ua cov khoom siv carbon fiber kom tsis txhob muaj teeb meem kev ua qias tuaj ib puag ncig los ntawm cov ntaub tsis-woven uas muaj cov nplaim taws halogen.

II. Cov yam ntxwv tseem ceeb ntawm cov ntaub tsis-woven uas tau ua ntej oxidized: Cov txiaj ntsig sib txawv ncaj qha hais txog cov teeb meem ntawm qhov xwm txheej

Cov ntaub tsis-woven uas tau ua ntej oxidized spunlace tsom mus rau "kev hloov pauv ib puag ncig hnyav" ua nws lub hauv paus, ua ke nrog cov txiaj ntsig ntawm cov txheej txheem spunlace, tsim peb yam ntxwv sib txawv uas daws tau qhov teeb meem tseem ceeb ntawm cov teb tshwj xeeb:

1. Kev tiv taus kub siab + Tsis muaj dej ntws: Kev tawg ua qhov tseem ceeb ntawm kev tiv thaiv hluav taws

Rau cov xwm txheej xws li kev tua hluav taws thiab metallurgy qhov twg muaj "cov khoom kub siab kub hnyiab" thiab "hluav taws kub kis sai" muaj kev pheej hmoo tuag taus, cov ntaub tsis-woven uas tau ua ntej oxidized filament needling zam kev phom sij ntawm kev yaj thiab ntws ntawm cov ntaub tsis-woven. Piv txwv li, daim pam khiav tawm hluav taws, thaum raug hluav taws, tsuas yog carbonizes los ua ib txheej rwb thaiv tsev kub, tsis muaj kev pheej hmoo ntawm kev ntws thiab kub hnyiab, thiab tuaj yeem thaiv 1000 ° C nplaim taws hauv 30 vib nas this, muab lub sijhawm tseem ceeb rau kev khiav tawm, ua cov khoom siv tseem ceeb ntawm cov khoom siv tiv thaiv hluav taws kub siab.

2. Kev tiv thaiv xeb + Lub zog siab: Kev daws teeb meem ruaj khov rau cov xwm txheej kev lag luam

Piv nrog cov ntaub tsis-woven uas tiv taus xeb uas "tiv taus xeb tab sis muaj zog tsawg" lossis "muaj zog siab tab sis tsis tiv taus xeb", cov ntaub pre-oxidized filament needling non-woven ua tiav ob qho kev tawg ntawm "kev tiv taus xeb thiab lub zog". Piv txwv li, daim ntaub lim dej tiv thaiv xeb hauv lub chaw ua haujlwm tshuaj lom neeg, nws tuaj yeem tiv taus cov kua qaub thiab alkali corrosion thiab tiv taus qhov cuam tshuam siab thaum lub sijhawm lim dej, nrog lub neej ntev dua ob npaug ntawm cov lim dej ib txwm muaj, txo cov nqi hloov pauv.

3. Kev ruaj khov ntawm cov qauv + Kev ua haujlwm ua ke: Kev hloov kho kom haum rau cov xwm txheej meej

Hauv cov teb xws li aerospace thiab precision manufacturing nrog cov kev cai nruj rau kev ua haujlwm ntawm cov khoom siv, cov ntaub pre-oxidized spunlace non-woven tuaj yeem ua tau raws li qhov xav tau tshwj xeeb los ntawm kev hloov kho cov qauv thiab kev ua haujlwm. Piv txwv li, lub satellite khoom siv sealing pad, nws tsis tsuas yog muaj qhov kub thiab txias ntawm -40 ° C txog 180 ° C kev ruaj khov, tab sis kuj ua ke nrog cov txheej conductive kom ua tiav kev tawm hluav taws xob, thaum tswj cov yam ntxwv sib dua, zoo meej rau qhov chaw ib puag ncig ntawm qhov chaw.

III. Cov teb tseem ceeb ntawm cov ntaub tsis-woven uas tau ua ntej oxidized: Cov ntaub ntawv tseem ceeb rau cov xwm txheej tshwj xeeb

Nyob ntawm cov txiaj ntsig thiab cov yam ntxwv saum toj no, cov ntaub tsis-woven uas tau ua ntej oxidized tau dhau los ua "cov khoom siv tseem ceeb" hauv plaub qhov chaw tseem ceeb ntawm kev tiv thaiv hluav taws, kev tsim khoom lag luam, kev ntxuav ib puag ncig, thiab kev tsav dav hlau, txhawb kev txhim kho kev nyab xeeb thiab kev ua tiav ntawm cov lag luam cuam tshuam:
