Dab tsi yog alkali-dawb chopped strand lev?
I. Kev nkag siab ua ntej: Qhov tseeb yog dab tsiFiberglass Chop Strand Mat?
Fiberglass tws strand lev, tseem hu ua tws fiberglass filament lev, yog ib qho uas tsis yog -woven reinforcing khoom ua los ntawm alkali-dawb iav fiber yarn.
Yooj yim tso: Nruam iav fiber ntau filaments raug txiav mus rau hauv cov ntu ntawm kwv yees li 50 hli. Cov chopped fibers no ces muab faib ua randomly thiab sib npaug, thiab sib koom ua ke nrog polyester hmoov los yog emulsion binder nyob rau hauv tshav kub, thaum kawg tsim ib tug mos, uniform, thiab muaj zog iav fiber lev daim ntawv.
Nws tsis yog ntaub ntaub, tab sis yog ib daim ntawv uas tsis yog -woven lev. Qhov sib faib ntawm cov fibers yog qhov tseem ceeb rau nws qhov kev sib luag thiab kev yooj yim ntawm molding.
II. Cov yam ntxwv tseem ceeb: Vim li cas nws thiaj li muaj txiaj ntsig?
Chopted strand lev tuaj yeem dhau los ua "universal substrate" rau cov ntaub ntawv sib xyaw vim cov txiaj ntsig tsis tuaj yeem hloov tau:
1. Isotropic thiab Uniform Stress Distribution
Qhov sib txawv tsis tu ncua ntawm cov iav fibers, tsis zoo li cov ntaub npuag uas tsuas muaj warp thiab weft lub zog, ua rau cov khoom siv nrog cov khoom sib npaug ntawm txhua qhov kev qhia, muab kev ruaj ntseg ntau dua hauv kev cuam tshuam, khoov tsis kam, thiab qaug zog.
2. Ceev Resin Impregnation thiab yooj yim defoaming
Kev sib raug zoo zoo nrog cov polyester thiab epoxy resins tsis txaus, uas ua rau impregnation sai, tsawg npuas thaum lub sij hawm thov, ib tug du nto, siab ceev nyob rau hauv cov khoom tiav, thiab tsawg defects.
3. Mos thiab hloov tau rau cov duab tsis yooj yim
Saj zawg zog thiab ua tau zoo heev, nws tuaj yeem nruj raws li qhov chaw nkhaus thiab cov pwm tsis zoo, ua kom yooj yim rau tes nteg -nce, compression molding, thiab SMC txheej txheem.
4. Uniform Thickness thiab ruaj khov zoo
Qhov hnyav ntawm ib chav tsev, tsis muaj impurities thiab burrs, kom ntseeg tau siab sib xws hauv kev tsim khoom loj thiab pab txhawb tus nqi thiab kev tswj kom zoo.
5. Lub teeb yuag, siab zog, thiab corrosion kuj
Tsis tshua muaj lub ntiajteb txawj nqus, siab zog, thiab tiv taus cov kua qaub, alkalis, dej, thiab kev laus, ua rau nws tsim nyog rau qhov chaw hnyav xws li kev tiv thaiv corrosion, kev siv sab nraum zoov, thiab kev ua tshuaj lom neeg.
III. Main Classifications: Yuav xaiv li cas los ntawm Adhesive
Raws li hom nplaum, tws strand lev feem ntau muab faib ua ob hom, sib xws rau cov txheej txheem sib txawv:
- Powdered Chopped Strand Mat: Siv cov hmoov binders, ua rau cov khoom muag muag nrog lub zog nruab nrab, haum rau kev siv tes nteg-nce, cov ntaub ntawv, cov khoom siv hauv chav dej, thiab lwm yam khoom loj- cov khoom lag luam.
- Emulsion Chopped Strand Mat: Siv cov emulsion binders, ua rau cov impregnation sai dua, smoother nto, thiab muaj zog ntub dej ntau dua, haum rau siab -kawg fiberglass, automotive qhov chaw, thiab cov nplooj ntawv translucent qhov zoo li thiab efficiency tseem ceeb heev.
Thaum yuav khoom, tsuas yog phim cov txheej txheem, hom resin, thiab qhov xav tau ntawm qhov chaw; tsis tas yuav overthink complex parameters.
IV. Daim Ntawv Thov Scenarios: Cov Khoom Siv Tsis Pom Zoo Muab zais nyob ib puag ncig peb
Choped strand lev muaj ntau yam kev siv ntau dua li koj xav, npog yuav luag txhua yam ntawm lub neej thiab kev lag luam:
- Chav da dej: chav da dej, chav da dej, ntxhua khaub ncaws; ruaj thiab nrog ib tug du nto.
- Automotive Lightweighting: Bumpers, sab hauv vaj huam sib luag, trunk partitions, headliners; txo qhov hnyav thaum txhim kho kev nyab xeeb.
- Kev Tiv Thaiv Tshuaj Tiv Thaiv: Cov tso tsheb hlau luam, cov kav dej, tiv thaiv - cov kab xeb, cov kav dej txias; resistant rau acid thiab alkali corrosion, ncua cov khoom siv lifespan.
- Cov Khoom Siv Hauv Tsev: Skylights, waterproof membranes, insulation reinforcement layers, decorative panels; huab cua-resistant, fireproof, thiab hnav.
- Shipbuilding thiab Amusement Facilities: Hulls, decks, seats, slides; dej-resistant, cuam tshuam-resistant, thiab ntev- lub sij hawm ruaj khov.
- Cua zog thiab rwb thaiv tsev: Cua turbine hniav linings, rwb thaiv tsev boards; txhim kho toughness thiab rwb thaiv tsev kev ua tau zoo.
Nyob rau hauv luv luv, tws strand lev (CSH) yuav siv tau rau tej lub teeb yuag, siab -lub zog, corrosion-resistant, thiab yooj yim moldable composite khoom.
V. Cov khoom sib piv: Qhov sib txawv yooj yim los ntawm lwm cov ntaub ntawv fiberglass
Ntau tus neeg tsis tuaj yeem paub qhov txawv ntawm cov ntaub qhwv cov ntaub, cov ntaub qhwv, thiab cov lev txuas ntxiv. Nov yog ib qho lus piav qhia yooj yim:
- Woven Fabric: Woven, siab zog nyob rau hauv ob qho tib si warp thiab weft cov lus qhia, haum rau load-cov kabmob cov yam ntxwv.
- Chopped Strand Mat: Tsis yog -woven, randomized kev taw qhia, sib npaug kev ua tau zoo, yooj yim rau pwm, haum rau txheej txheej thiab dav dav.
- Nruam lev: Nrog cov fibers tsis tu ncua, nws boasts lub zog ntau dua thiab haum rau siab -kawg structural Cheebtsam.
Rau txhua hnub fiberglass tes nteg-nce, dav dav- cov khoom siv, kev tiv thaiv corrosion, thiab cov khoom siv hauv chav dej, chopped strand lev (CSM) feem ntau yog qhov kev xaiv.
