Spunlace nonwoven ntawm pre-oxygenated fiber ntau
Khoom Taw Qhia:
Pre-oxidized filament nonwoven npuag yog cov khoom siv ua haujlwm ua los ntawm pre-oxidized filament (polyacrylonitrile pre-oxidized fiber) los ntawm cov txheej txheem nonwoven xws li needling thiab spunlace. Nws lub ntsiab kom zoo dua yog nyob rau hauv nws cov nplaim retardancy. Nws tsis xav tau cov nplaim hluav taws xob ntxiv. Thaum raug hluav taws, nws tsis hlawv, yaj los yog poob. Nws tsuas yog carbonizes me ntsis thiab tsis tso cov pa phem thaum hlawv, ua kom pom kev nyab xeeb zoo.
Lub caij no, nws muaj kev kub siab ua haujlwm zoo heev thiab tuaj yeem siv rau hauv ib puag ncig ntawm 200-220 ℃ rau lub sijhawm ntev, thiab tuaj yeem tiv taus qhov kub siab tshaj 400 ℃ rau lub sijhawm luv luv, tseem tuav lub zog ntawm qhov kub thiab txias. Piv nrog cov khoom siv hluav taws xob tsis zoo, nws yog softer, yooj yim rau txiav thiab txheej txheem, thiab tseem tuaj yeem ua ke nrog lwm cov ntaub ntawv.
Nws daim ntawv thov tsom mus rau kev tiv thaiv hluav taws, xws li txheej sab hauv ntawm cov hluav taws kub, cov ntaub thaiv hluav taws kub, cov nplaim hluav taws qhwv cov kab hluav taws xob, cov nplaim hluav taws kub hnyiab rau cov tsheb sab hauv, thiab cov roj teeb electrode separators, thiab lwm yam.
YDL Nonwovens tuaj yeem tsim ua ntej-oxygenated filament non-woven fabrics xws li 60 mus rau 800 grams, thiab lub thickness ntawm lub qhov rooj dav tuaj yeem kho.
Cov hauv qab no yog kev taw qhia rau cov yam ntxwv thiab daim ntawv thov teb ntawm pre-oxygenated xov hlau:
I. Cov yam ntxwv tseem ceeb
Intrinsic nplaim taws retardancy, nyab xeeb thiab tsis muaj teeb meem: Tsis xav tau cov nplaim hluav taws xob ntxiv. Nws tsis hlawv, yaj los yog poob thaum raug hluav taws, tab sis tsuas yog undergoes carbonization me ntsis. Thaum lub sij hawm combustion txheej txheem, tsis muaj cov pa phem los yog cov pa phem raug tso tawm, uas tuaj yeem tiv thaiv cov nplaim taws thiab ua tau raws li cov qauv kev nyab xeeb siab.
High-temperature resistant thiab zoo zoo tuav: Nws yuav siv tau nyob rau hauv ib puag ncig ntawm 200-220 ℃ rau lub sij hawm ntev thiab tuaj yeem tiv taus qhov kub siab tshaj 400 ℃ rau lub sijhawm luv. Nws tsis yooj yim rau deformation los yog tawg nyob rau hauv high-temperature ib puag ncig thiab tseem muaj peev xwm tswj tau ib tug tej yam mechanical zog, ua tau raws li qhov yuav tsum tau ntawm high-temperature scenarios.
Kev ntxhib los mos thiab kev ua haujlwm zoo heev: Kev vam khom ntawm cov txheej txheem spunlace, cov khoom tiav yog fluffy, mos thiab muaj tes zoo. Piv nrog rau rab koob-punched pre-oxygenated filament non-woven npuag lossis cov khoom siv hluav taws xob tsis zoo (xws li iav fiber ntau daim ntaub), nws yooj yim dua los txiav thiab xaws, thiab tseem tuaj yeem ua ke nrog lwm cov ntaub ntawv xws li paj rwb thiab polyester kom nthuav daim ntawv thov.
Kev ua haujlwm ruaj khov: Nws muaj qee yam kev laus ua haujlwm thiab acid thiab alkali tsis kam. Hauv kev khaws cia txhua hnub lossis ib puag ncig kev lag luam, nws tsis tuaj yeem ua tsis tiav vim yog ib puag ncig thiab muaj lub neej ua haujlwm ntev.
II. Main Application Fields
Hauv kev tiv thaiv tus kheej: Raws li cov txheej txheej sab hauv lossis hauv ob sab phlu ntawm cov hluav taws kub, hluav taws kub-resistant aprons, thiab cov hnab looj tes tiv thaiv tshav kub, nws tsis tsuas yog ua lub luag haujlwm hauv nplaim hluav taws thiab rwb thaiv tsev kub, tab sis kuj tseem txhim kho kev hnav khaub ncaws los ntawm nws cov ntaub mos mos. Nws kuj tseem tuaj yeem ua rau hauv daim pam tawm thaum muaj xwm txheej ceev, uas yog siv los qhwv tib neeg lub cev sai sai lossis npog cov khoom siv hluav taws xob ntawm qhov chaw tua hluav taws, txo qhov kev pheej hmoo ntawm kev kub nyhiab.
Hauv kev ua haujlwm ntawm lub tsev thiab kev nyab xeeb hauv tsev: Nws yog siv rau cov ntaub thaiv hluav taws, cov ntaub thaiv hluav taws kub, thiab cov nplaim hluav taws kub hnyiab, ua kom pom cov qauv tiv thaiv hluav taws hauv tsev thiab ua kom tsis muaj hluav taws kub hauv tsev. Nws tseem tuaj yeem qhwv cov thawv xa khoom hauv tsev thiab cov kav dej, txo cov hluav taws kub hnyiab los ntawm hluav taws xob luv luv lossis roj xau.
Hauv kev thauj mus los thiab kev lag luam: Nws yog siv los ua cov nplaim hluav taws kub nyhiab hauv ob sab phlu rau cov rooj zaum, ntsuas vaj huam sib luag thiab cov hlua hluav taws xob hauv cov tsheb sab hauv thiab cov tsheb ciav hlau ceev, ua tau raws li cov qauv kev tiv thaiv hluav taws rau cov khoom siv thauj mus los thiab txo cov pa phem ntawm cov pa phem hauv hluav taws kub. Nws kuj tseem tuaj yeem siv los ua cov nplaim hluav taws kub hnyiab rau cov kab hluav taws xob thiab cov xaim hluav taws xob los tiv thaiv kev sib kis ntawm cov nplaim taws mus rau lwm qhov chaw thaum cov kab hluav taws kub.
High-temperature industrial auxiliary fields: Nyob rau hauv metallurgy, tshuaj, thiab fais fab kev lag luam, nws yog siv los ua cua sov rwb thaiv tsev npog ntaub rau high-temperature ua hauj lwm, ib ntus fireproof shielding rau cov khoom tu, los yog yooj yim wrapping cov ntaub ntawv rau high-temperature pipelines. Nws tuaj yeem tiv taus qhov kub thiab txias ntawm lub sijhawm luv thiab yooj yim rau nteg, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
