Dab tsi yog qhov txawv ntawm fiberglass lev thiab zoo tib yam nonwoven ntaub?
I. Raw Khoom: Inorganic iav Fiber vs. Organic Synthetic Fiber
Fiberglass levyog ib yam khoom uas tsis yog organic uas tsis yog{0}}hlau fiber ntau. Nws cov khoom siv tseem ceeb yog alkali- iav dawb (E- iav), uas yog yaj ntawm qhov kub thiab txias thiab kos rau hauv cov iav txuas ntxiv nrog txoj kab uas hla ntawm ob peb micrometers. Nws tsis muaj alkali hlau oxides thiab muaj tshuaj lom neeg ruaj khov heev. Cov khoom siv raw no yog los ntawm cov ntxhia hauv ntuj thiab yog qhov tseem ceeb ntawm cov khoom siv silicate inorganic, muaj qhov zoo ntawm iav, xws li siab -kub tsis kam, corrosion resistance, thiab rwb thaiv tsev.
Ib txwm tsis yog- ntaub npuag, ntawm qhov tod tes, yog cov organic polymer fiber ntau. Cov ntaub ntawv tseem ceeb yog petrochemical - muab cov organic hluavtaws fibers xws li polypropylene (PP), polyester (PET), thiab viscose fiber. Qee cov pej xeem versions kuj tseem muaj cov fibers ntuj xws li paj rwb thiab ntaub pua chaw. Nws cov khoom siv raw yog cov organic polymer, uas yog qhov tseeb txiav txim siab tias nws qhov siab -kub tsis kam thiab tshuaj lom neeg ruaj khov yog qhov qis dua rau cov iav fiber ntau. Nws yog ib qho hluav taws kub thiab yooj yim aged organic khoom.
II. Cov txheej txheem ntau lawm: ntub / Kub- Melt Forming vs. Koob Punching / Kub-Roll Bonding
Fiberglass lev feem ntau siv cov txheej txheem ntub dej: chopped iav fibers yog dispersed nyob rau hauv dej los ua ib tug slurry, uas yog ces tsim los ntawm papermaking, lub cev qhuav dej, ziab, thiab thaum kawg kho nrog ib tug tshwj xeeb inorganic binder. Some high-end models utilize a hot-melt process, which is entirely free of chemical pollution, resulting in uniform fiber distribution, uniform mat density, controllable thickness, and production processes that better comply with industrial environmental standards. Cov khoom tiav lawm muaj cov qauv ntom ntom thiab ruaj khov siab.
Ordinary nonwoven fabrics yog tsim los siv rab koob punching, kub dov, thiab spunbonding: organic fibers yog qhib, carded, thiab nteg rau hauv ib lub web, ces sib txuas los ntawm rab koob xuas nrig ntaus, siab - kub dov, los yog tshuaj bonding los ua ib tug lev. Cov txheej txheem no muaj kev cuam tshuam qis rau kev nkag mus thiab kev ua haujlwm ntau dua, tab sis cov fibers tsuas yog lub cev entangled lossis txuas nrog cov organic adhesives, uas ua rau cov qauv xoob uas ua rau deformation thiab delamination hauv kev ntxhov siab, thiab tag nrho lub zog qis dua li cov iav fiber ntau.
III. Core Performance: Industrial-Grade Durability vs. Civilian-Qib Lub Hom Phiaj
1. Kev kub siab tiv thaiv thiab nplaim hluav taws kub
Fiberglass muaj peev xwm tiv taus ntev -lub sijhawm ua haujlwm kub ntawm 300-500 degree, nrog rau qhov kub siab dua tam sim no. Nws yog Chav Kawm A uas tsis yog- cov khoom siv hluav taws xob, txhais tau tias nws tsis hlawv, poob, lossis tso cov pa phem thaum raug hluav taws kub hnyiab, ua rau nws zoo kawg nkaus rau kev siv kub thiab hluav taws kub.
Ib txwm tsis yog- cov ntaub npuag, ntawm qhov tod tes, tsuas yog tiv taus ntev -lub sijhawm kub ntawm 80-150℃. Lawv yog cov flammable, sai yaj thiab hlawv thaum sib cuag nrog hluav taws, tso pungent thiab teeb meem gases. Lawv tsuas yog tsim nyog rau kev siv pej xeem ntawm qhov kub thiab txias thiab tsis tuaj yeem siv nyob rau hauv siab -kub, nplaim hluav taws-retardant chaw ua haujlwm.
2. Tshuaj Stability
Fiberglass muaj peev xwm tiv taus cov kua qaub, alkalis, roj, thiab cov kuab tshuaj organic. Nws tsis yog yooj yim hydrolyzed los yog hnub nyoog, thiab muaj kev pab cuam lub neej ntawm ob peb xyoos nyob rau hauv sab nraum zoov los yog hnyav tshuaj ib puag ncig uas yuav luag tsis muaj degradation.
Tej yam uas tsis yog - woven fabrics muaj tsis zoo corrosion kuj. Lawv yog cov nquag mus rau kev laus, embrittlement, thiab pulverization thaum raug cov kua qaub, alkalis, ultraviolet lub teeb, thiab kub kub. Lawv poob lawv cov khoom siv kho tshuab tom qab tsuas yog ob peb lub hlis ntawm kev siv sab nraum zoov thiab tsis haum rau kev ua haujlwm hnyav.
3. Rwb thaiv tsev thiab cov cuab yeej cuab tam
Fiberglass lev yog ib yam khoom zoo -cov ntaub ntawv insulating zoo nrog cov ntim siab tiv taus thiab kev ua haujlwm ruaj khov. Nws kuj khav theeb lub zog tensile zoo heev, tsim kua muag ua haujlwm, thiab tsis tshua muaj zog ntawm qhov ruaj khov, seem tsis hloov thiab tsis- ntsws thaum siv.
Ordinary nonwoven fabrics muaj kev rwb thaiv tsev tsis zoo, muaj kev cuam tshuam rau hluav taws xob zoo li qub, muaj lub zog tsis muaj zog, yooj yim puas, thiab shrink thiab deform yooj yim thaum raug tshav kub los yog ya raws, tsis ua raws li qhov yuav tsum tau ntawm rwb thaiv tsev thiab load- bearing industrial applications.
IV. Daim Ntawv Thov Scenario: Kev Lag Luam Kev Lag Luam Kev Lag Luam vs. Civil Basic Sector
Fiberglass lev tsom mus rau siab -kawg muaj xwm txheej: dav siv nyob rau hauv lub zog tshiab roj teeb rwb thaiv tsev, Circuit Court board substrates, pipeline corrosion tiv thaiv, ru tsev waterproof membrane puag, hluav taws xob rwb thaiv tsev, lim cov ntaub ntawv, fiberglass reinforcement, thiab lwm yam teb nrog stringent kev ua tau zoo. Nws yog lub hauv paus tseem ceeb rau kev tsim khoom lag luam thiab siab - cov khoom siv hauv tsev kawg.
Cov ntaub ntawv tsis-woven feem ntau yog siv rau hauv cov neeg pej xeem thiab tsawg- qhov kawg ntawm kev lag luam: lub qhov ncauj qhov ntswg niaj hnub, lub hnab yuav khoom, cov hnab ntim khoom, cov ntaub ntawv ua liaj ua teb, cov khoom siv tu cev, thiab lwm yam, hais txog tus nqi qis thiab siv ib zaug, thiab tsis tuaj yeem ua tau raws li kev lag luam - qib yuav tsum tau ua.
V. Kev xaiv khoom: Xaiv cov khoom raws li qhov xav tau, tsis lees txais cov khoom hloov pauv
Feem ntau: Fiberglass lev yog ib qho inorganic industrial-qib siab- cov khoom ua tau zoo, cov yam ntxwv ntawm qhov kub thiab txias, tiv thaiv corrosion, rwb thaiv tsev, thiab lub zog siab. Nws yog qhov tsim nyog rau kev lag luam hnyav, nrog tus nqi siab dua tab sis lub neej ua haujlwm ntev thiab kev ua haujlwm ruaj khov. Ordinary non-woven fabric yog organic civilian-qib cov khoom siv yooj yim, tus yam ntxwv los ntawm tus nqi qis thiab kev ua haujlwm yooj yim. Nws tsuas yog tsim nyog rau cov xwm txheej yooj yim uas muaj qhov kub thiab txias thiab tsis muaj qhov tshwj xeeb.
