Hauv kev ua haujlwm muaj kev pheej hmoo siab xws li kev tsim tshuaj lom neeg, kev tua hluav taws, thiab pov tseg tshuaj lom neeg, kev nyab xeeb ntawm cov neeg ua haujlwm pem hauv ntej yog qhov tseem ceeb. Lawv "ob daim tawv nqaij" - khaub ncaws tiv thaiv - yog ncaj qha ntsig txog lawv txoj sia nyob. Nyob rau hauv xyoo tas los no, cov khoom siv hu ua "high-barrier composite spunbond fabric" tau tshwm sim los ua cov khoom tseem ceeb, thiab nrog nws cov kev ua tau zoo tshaj plaws, nws tau dhau los ua cov khoom tseem ceeb uas tsis muaj teeb meem rau cov khaub ncaws tiv thaiv kab mob siab heev, tsim kom muaj kev tiv thaiv kev nyab xeeb.
Lub raj mis ntawm cov khoom siv tiv thaiv tsoos
Ua ntej nkag siab txog high-barrier composite spunbond fabrics, peb yuav tsum tau saib cov kev cov nyom ntawm cov khoom siv tsoos:
1. Roj Hmab / Yas Coated Fabrics: Thaum muab cov khoom thaiv zoo, lawv hnyav, tsis muaj pa, thiab tsis xis nyob rau hnav, yooj yim ua rau kub ntxhov thiab cuam tshuam rau kev ua haujlwm thiab lub sijhawm ntev.
2. Ordinary Nonwoven Fabrics: Lub teeb yuag thiab tus nqi qis, tab sis tsis muaj qhov cuam tshuam txaus, ua rau lawv tsis tuaj yeem tiv thaiv kev nkag mus ntawm cov kua lossis cov tshuaj lom neeg gaseous.
3. Microporous Membrane Composite Fabrics: Thaum muab kev ua pa zoo dua, lawv lub peev xwm barrier tseem txwv rau cov tshuaj lom neeg uas muaj qhov me me me me lossis cov khoom siv tshuaj tshwj xeeb, thiab lawv cov kav ntev yuav tsis txaus.
Cov bottlenecks no tau txhawb qhov kev xav tau ntawm cov khoom siv tshiab uas tuaj yeem muab kev tiv thaiv "ironclad" thaum tseem ua kom muaj kev nplij siab thiab kav ntev.
High-Barrier Composite Spunbond Fabric: Kev Ntsuam Xyuas
High-barrier composite spunbond fabric tsis yog ib qho khoom siv, tab sis "sandwich" qauv uas nruj nreem khi cov txheej txheem sib txawv ua ke siv cov txheej txheem siab heev. Nws cov txiaj ntsig tseem ceeb yog los ntawm qhov no:
1. Spunbond Nonwoven Base Layer: Lub cev muaj zog "Skeleton"
Kev Ua Haujlwm: Siv cov khoom siv raw xws li polypropylene (PP) lossis polyester (PET), lub zog siab, tsim kua muag-resistant, thiab tensile-resistant puag txheej yog tsim ncaj qha los ntawm spunbonding. Cov txheej no muab cov cuab yeej zoo heev thiab qhov ruaj khov rau tag nrho cov khoom, kom ntseeg tau tias cov khaub ncaws tiv thaiv tsis yooj yim puas thaum ua haujlwm nyuaj.
2. High-Barrier Functional Layer: Ib qho ntse "Shield"
Qhov no yog qhov tseem ceeb ntawm cov thev naus laus zis. Feem ntau, cov txheej txheem co-extrusion tshuab tshuab yog siv los ua cov khoom siv ntau yam kev ua haujlwm siab (xws li polyethylene, ethylene-vinyl cawv copolymer EVOH, polyamide, thiab lwm yam) rau hauv cov yeeb yaj kiab uas nyias nyias tab sis ua haujlwm tau zoo.
High Barrier Properties: Cov ntaub ntawv zoo li EVOH muaj qhov cuam tshuam tsis zoo rau cov kuab tshuaj organic, roj, thiab ntau yam roj, tiv thaiv kev nkag mus ntawm cov kua thiab roj ntau yam tshuaj lom neeg.
Selective Penetration: Los ntawm kev tsim cov khoom sib txawv thiab cov txheej txheem tsim, tsom thiab tiv thaiv cov tshuaj muaj txiaj ntsig zoo (xws li acids, alkalis, thiab cov kuab tshuaj lom) tuaj yeem ua tiav.
3. Cov txheej txheem sib xyaw: Ib qho nyiaj tsis sib haum
Los ntawm cov txheej txheem siab heev xws li kub xovxwm lamination thiab nplaum dot lamination, cov yeeb yaj kiab siab yog ruaj khov rau hauvspunbond ntaub puag txheej. Cov qauv sib xyaw no zam cov teeb meem xws li delamination thiab bubbling, ua kom muaj kev ncaj ncees thiab kev ntseeg siab ntawm cov khoom thoob plaws hauv nws lub neej kev pabcuam.
Vim li cas nws thiaj dhau los ua ib yam khoom tseem ceeb?— Plaub Qhov Zoo Tshaj Plaws
High-barrier composite spunbond npuag sawv tawm vim nws zoo kawg nkaus sib npaug ntau qhov tseem ceeb ntawm kev tiv thaiv khaub ncaws:
Advantage 1: Kev Tiv Thaiv Kev Nyab Xeeb Qhov Kawg
Ua haujlwm zoo thaiv ntau yam tshuaj phom sij, suav nrog cov tshuaj tsw qab hydrocarbons, halogenated hydrocarbons, acids, thiab alkalis. Nws impermeability deb tshaj lub teb chaws cov qauv thiab thoob ntiaj teb cov qauv xws li European EN thiab American NFPA, muab cov neeg siv nrog "qhov kawg tiv thaiv."
Advantage 2: Superior Durability thiab Reliability
Lub hauv paus spunbond ntaub muab nws zoo heev tensile, tsim kua muag, thiab abrasion tsis kam, ua rau nws tiv taus lub cev kev nyuaj siab nyob rau hauv hnyav ua hauj lwm ib puag ncig thiab txo cov kev pheej hmoo ntawm kev tiv thaiv tsis ua hauj lwm vim khawb thiab hnav.
Advantage 3: Ua kom muaj kev nplij siab zoo heev
Muab piv rau cov khaub ncaws uas tsis yog breathable rubber tiv thaiv, siab-barriercomposite spunbond ntaubfeem ntau muaj zoo heev ** breathability thiab ya raws permeability **. Nws tso cai rau hws ua los ntawm lub cev raug tshem tawm raws li dej vapor, txo cov condensation sab hauv, ua kom cov neeg hnav kom qhuav, txo cov thermal load rau cov neeg ua haujlwm, thiab txhim kho kev ua haujlwm thiab kev nyab xeeb.
Qhov Zoo Plaub: Lub teeb yuag thiab yoog raws
Cov khaub ncaws tiv thaiv ua los ntawm cov khoom siv no yog sib zog thiab softer dua li cov khaub ncaws tiv thaiv roj hmab / PVC thaum muab kev tiv thaiv tib yam lossis ntau dua. Qhov no ua rau cov neeg hnav muaj kev ywj pheej ntau dua ntawm kev txav mus los, ua kom yooj yim rau kev ua haujlwm me me lossis kev siv siab.
Daim ntawv thov scenarios thiab yav tom ntej Prospects
Tam sim no, high-barrier composite spunbond fabrics yog dav siv nyob rau hauv:
Kev Lag Luam Tshuaj: Kev tshuaj xyuas niaj hnub, kev tu cov cuab yeej siv, thiab kev tuav tshuaj lom neeg.
Hluav taws kub thiab cawm: Kev siv tshuaj lom neeg kev sib tsoo thiab kev tuav pov hwm cov khoom phom sij.
Kev Tswj Xyuas Thaum Muaj Xwm Ceev: Cov lus teb xwm txheej ceev hauv qhov chaw los ntawm pej xeem kev ruaj ntseg thiab ib puag ncig tiv thaiv lub tuam tsev.
Laboratory Safety: Kev khiav hauj lwm uas muaj cov tshuaj lom thiab corrosive heev.
Yav tom ntej Trends: Nyob rau hauv lub neej yav tom ntej, cov ntaub ntawv no yuav tsim rau ** ntse thiab multifunctional ** daim ntaub ntawv. Piv txwv li, kev sib koom ua ke ntawm kev hnov cov thev naus laus zis los saib xyuas cov tshuaj nkag mus rau ntawm cov khaub ncaws saum npoo thiab tus neeg hnav lub cev lub cev hauv lub sijhawm; txhim kho biodegradable thiab ib puag ncig tus phooj ywg cov ntaub ntawv muaj teeb meem kom ua tiav kev nyab xeeb ntsuab thoob plaws lub neej voj voog.
Xaus
Kev nyab xeeb yog qhov tseem ceeb, thiab cov khaub ncaws tiv thaiv yog kab kawg ntawm kev tiv thaiv rau lub neej. High-barrier composite spunbond npuag, los ntawm kev sib sib zog nqus ntawm cov ntaub ntawv science thiab textile technology, ua tiav reconciles qhov seemingly contradictory xav tau ntawm "siab tiv thaiv" thiab "siab nplij siab." Nws daim ntawv thov dav dav tsis muaj qhov tsis ntseeg tau muab kev txhawb nqa rau kev nyab xeeb ntawm cov neeg ua haujlwm hauv kev lag luam uas muaj kev pheej hmoo siab, cim qhov pib ntawm lub sijhawm tshiab ntawm cov khoom siv tiv thaiv tus kheej ua haujlwm siab.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
