Cov yam ntxwv ntawm non-woven geotextile thiab Zaozhuang non-woven npuag yog txawv
Cov yam ntxwv ntawm geotextile
Geotextile, tseem hu ua geotextile, yog cov dej nqus cov khoom siv ntsuas geotechnical ua los ntawm cov khoom siv fiber ntau uas tau siv los yog woven. Geotextile yog ib qho ntawm cov khoom tsim los ntawm cov khoom siv tshiab geotechnical xeem. Cov khoom tiav yog nyob rau hauv daim ntawv ntawm daim ntaub, nrog ib tug dav dav ntawm 4-6 meters thiab ib tug ntev ntawm 50-100 meters. Geotextiles muab faib ua spun geotextiles thiab non-woven filament geotextiles.
Cov yam ntxwv ntawm cov ntaub tsis-woven
Non-woven fabric, tseem hu ua non-woven handmade fabrics, yog tsim los ntawm taag los yog arbitrary chemical fibers thiab yog ib tug tshiab tiam ntawm ib puag ncig tiv thaiv cov ntaub ntawv. Nws muaj cov yam ntxwv ntawm impermeability, breathability, saj zawg zog, lub teeb yuag, tsis combustible, yooj yim heev rau yaj, nplua nuj thiab muaj yeeb yuj xim, zoo siab thiab tsis tshua muaj nqi, thiab yuav siv tau nyob rau hauv ib tug recyclable system. Yog tias cov khoom siv polypropylene (PP) hmoov siv los ua cov khoom siv raw, nws yog tsim thiab tsim los ntawm cov txheej txheem txuas ntxiv ntawm kev kub kub melting, spinning, nteg, nias thiab unwinding. Nws yog hu ua daim ntaub vim nws cov tsos thiab qee yam ntxwv.
Kev siv geotextile thiab non-woven npuag yog txawv
Kev siv tseem ceeb ntawm geotextile
Geotextiles feem ntau yog siv rau hauv kev sim geotechnical tej yaam num xws li kev txuag dej engineering, hluav taws xob engineering, thee mines, txoj kev, thiab railways. Lawv tuaj yeem siv los ua cov ntaub ntawv lim dej rau cov txheej txheem hauv av sib cais, cov khoom siv hauv cov kav dej rau cov chaw txuag dej, tsuas yog cov nroj tsuag tau txais txiaj ntsig, cov khoom siv hauv cov kav dej rau ntau txheej hauv tsev, cov ntaub ntawv pov tseg rau cov dej ntws thiab kev tiv thaiv txoj kab nqes, cov ntaub ntawv ribbed rau cov kab tsheb ciav hlau, txoj kev, thiab cov dav hlau khiav cov ntaub ntawv, cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. txias tsis kam, thiab tawg resistant cov ntaub ntawv rau asphalt txoj kev.
Kev siv tseem ceeb ntawm cov ntaub tsis-woven
(1) Cov ntaub ntawv tsis yog siv rau kev kuaj mob, kev kho mob, thiab kev tu ib puag ncig: cov khaub ncaws phais, cov khaub ncaws tiv thaiv, hnab tu cev, tiv thaiv lub ntsej muag, cov ntaub qhwv me nyuam, cov phuam so hauv pej xeem, cov ntaub so huv, cov ntaub so ntub, cov phuam so tes, cov phuam so tes, cov ntaub so ntswg mos, cov khoom siv zoo nkauj, cov ntaub qhwv lub cev, cov ntaub so ntswg thiab cov ntaub so ntswg.
(2) Zaozhuang non-woven npuag rau tsev kho kom zoo nkauj: phab ntsa ntawv, ntaub pua rooj, txaj txaj, txaj npog, thiab lwm yam.
(3) Zaozhuang non-woven npuag rau khaub ncaws: hauv ob sab phlu, nplaum nplaum, floc, zoo li paj rwb, ntau yam PVC hluavtaws tawv elastic fabrics, thiab lwm yam.
(4) Muaj qib Zaozhuang tsis-woven npuag; Flat ru tsev impermeable cov ntaub ntawv thiab fiberglass pobzeb boards, lifting cov ntaub ntawv, polishing cov ntaub ntawv, lim cov ntaub ntawv, rwb thaiv tsev txheej ntaub ntawv, cement hnab, geotextiles, npog ntaub, thiab lwm yam.
(5) Zaozhuang non-woven npuag rau kev ua liaj ua teb thiab tsiaj ua liaj ua teb: daim ntaub tu qoob loo, yub pov tseg daim ntaub, dej daim ntaub, thermal rwb thaiv tsev ntaub, thiab lwm yam.
(6) Lwm Zaozhuang non-woven fabrics: chaw paj rwb, thermal rwb thaiv tsev, suab rwb thaiv tsev thiab suab nrov txo cov ntaub ntawv, roj absorbing xav, pa luam yeeb lim lub qhov ncauj, tshuaj yej hnab ntim, cov ntaub ntawv khau, thiab lwm yam.
Cov txheej txheem ntau lawm ntawm geotextile thiab non-woven npuag yog txawv
Kev tsim cov txheej txheem ntawm geotextile
Luv fiber ntau geotextile yog ua los ntawm polyester luv fiber polyester ntaub los yog polypropylene ntaub ua raw khoom, uas yog qhib los ntawm lub unpacking tshuab, loosened los ntawm ib tug loosening tshuab, thiab ces muab tso rau hauv ib lub thawv cia. Nws yog tom qab ntawd kub-dov kom ua tiav siab ntom ntom, thiab tom qab ntawd nteg nrog plaub mus rau tsib txheej ntawm mesh. Tom qab peb rab koob tho cov txheej txheem suav nrog kev tho ua ntej, nuv ntses, thiab tho lub ntsiab, nws yog tsim los ntawm stretching thiab trimming npoo; Ntev filament geotextile, ntawm qhov tod tes, yog tsim los ntawm ib yam tshiab ntawm polyester nti hais raws li raw cov ntaub ntawv, melted nyob rau hauv high kub, punched thiab nteg rau hauv ib tug mesh, thiab ces ua tiav los ntawm ob koob tho txheej txheem: pre tho thiab re tho, ua raws li los ntawm ntug txiav thiab ncab.
Non-woven fabric production process flow
Cov ntaub tsis woven tsis yog tsim los ntawm interlacing thiab weaving paj rwb yarns ib tug los ntawm ib tug, tab sis los ntawm tam sim ntawd bonding cellulose ua ke siv lub cev los yog tshuaj txoj kev. Nws tsis muaj daim ntawv qhia warp thiab weft, thiab txiav thiab xaws tshuab yog yooj yim heev. Nws kuj yog lub teeb yuag thiab yooj yim rau cov duab. Muaj peb yam tseem ceeb rau kev tsim khoom:
(1) Spinning adhesion method: Siv lub hauv paus ntsiab lus ntawm yaj spinning, cov ntaub ntawv raw yog melted thiab tov nrog roj hmab, thiab ces extruded los ntawm ib tug spinning phaj los tsim ib tug zoo ntws ntawm yaj. Cov huab cua txias ceev thiab muaj zog yog siv los ua kom cov dej ntws zoo, thaum cov tshuaj fibers raug cuam tshuam los tsim cov filaments tas li. Los ntawm cov txheej txheem ntawm kev sib cais ntawm cov xov paj, ib qho sib npaug ntawm cov duab kos yog tsim, uas tau muab tso rau ntawm cov ntaub thaiv npog los tsim lub web fiber. Lub vev xaib fiber ntau tau txhawb nqa los ntawm cov qauv kub tying, rab koob tying qauv lossis dej dav hlau thiab ruaj khov rau daim ntawv Zaozhuang tsis-woven npuag.
(2) Melt txau txoj kev: Cov khoom molten extruded los ntawm ib tug ntsia hlau yog siv nyob rau hauv ib tug ceev ceev high-temperature cyclone gas generator kom raug cov dej ntws zoo ntawm cov khoom molten mus rau stretching ntawm polymer hlwb, uas ua rau zus tau tej cov polyester luv fibers zoo heev. Cov fibers no ces muab tso rau hauv ib lub mesh curtains los yog ib tug mesh roller nruas los tsim ib tug nruam luv fiber ntau network, uas yog ces ua tiav los ntawm tus kheej-nplaum nyhuv los yog lwm yam structural reinforcement cov tswv yim los tsim Zaozhuang non-woven npuag.
(3) Composite method: Ib lub tshuab meltblown nonwoven forming tshuab yog ntxiv ntawm ob spinning thiab bonding nonwoven forming tshuab los tsim cov kab ntau lawm, uas yog siv los tsim Zaozhuang nonwoven fabric nrog txheej spinning thiab bonding fiber webs thiab meltblown fiber webs.
Puas yog geotextile tib yam li cov ntaub tsis-woven? Cov saum toj no yog qhov sib txawv thiab kev sib txawv uas peb tau txheeb xyuas. Peb tos ntsoov yuav muab qee qhov kev pab rau koj.
Dongguan Liansheng Nonwoven Fabric Co., Ltd., cov chaw tsim khoom ntawm cov ntaub ntawv tsis-woven thiab non-woven fabrics, tsim nyog ntawm koj txoj kev ntseeg siab!
