Kev piav qhia ntxaws ntawm Daim Ntawv Thov Ntawm Fiberglass Chopped Strand Mat, Cov Khoom Siv Tseem Ceeb Rau Kev Siv Tsheb

I. Vim li cas Fiberglass Material Indispensable rau Automotive Lightweighting?

 

Lub hauv paus ntsiab lus ntawm kev siv lub tsheb sib tsoo yog qhov yooj yim: kom txo lub tsheb hnyav kom ntau li ntau tau thaum ua kom muaj zog thiab kev nyab xeeb. Cov ntaub ntawv qhia tau hais tias rau txhua 10% txo cov tsheb hnyav, kev siv hluav taws xob tuaj yeem txo los ntawm 6% mus rau 8%, kev tsav tsheb ntawm lub zog tshiab tuaj yeem nce li 5% mus rau 10%, thiab kev ncua kev ncua luv luv thiab tuav tau zoo dua.

 

Muaj peb txoj hauv kev tseem ceeb kom ua tiav qhov hnyav: kev ua kom zoo ntawm cov qauv, kev tsim khoom siab heev, thiab kev siv cov khoom siv tshiab. Kev hloov khoom siv yog qhov ncaj qha thiab nrawm tshaj plaws kom ua tiav cov txiaj ntsig.

 

Traditional steel has high density and is difficult to mold, while aluminum alloys and magnesium alloys are relatively expensive. Cov pa roj carbon fiber ntau, txawm hais tias muaj kev ua haujlwm siab tshaj -tier, yog tus nqi kim heev uas yuav tsum tau txais yuav. Fiberglass composite cov ntaub ntawv zoo kawg nkaus sib npaug kev ua tau zoo, nqi, thiab kev ua tau zoo, muaj cov hauv qab no zoo:

- Tsawg ceev, muaj zog tshwj xeeb, thiab txo qhov hnyav hnyav;

- Kev tiv thaiv corrosion, kev laus ua haujlwm, thiab kev ua haujlwm ntev;

- Saj zawg zog molding, muaj peev xwm ntawm integrally molding complex qhov chaw;

- Cov khoom siv ntau, tus nqi siab -kev ua tau zoo, haum rau kev tsim khoom loj.

 

Ntawm cov khoom siv iav fiber ntau,chopped strand lev (CSM)stands raws li ib tug mainstream reinforcing khoom rau automotive lightweighting vim nws zoo heev uniformity, ceev impregnation, seem stability, thiab balanced mechanical zog.

 

II. Dab tsi yog chopped strand lev (CSM) thiab nws qhov zoo yog dab tsi?

 

CSM yog ib daim ntawv-zoo li cov khoom siv txhawb zog los ntawm kev txiav alkali-dawb iav fiber ntau filaments rau hauv qhov ntev, sib npaug sib npaug ntawm qhov tsis yog - kev taw qhia, thiab khi lawv nrog cov tshuaj nplaum. Nws yog ib qho ntawm feem ntau siv substrates rau fiberglass reinforced plastics (FRP) thiab cov ntaub ntawv sib xyaw.

 

Hauv kev siv tsheb, nws cov txiaj ntsig tseem ceeb yog qhov tshwj xeeb:

1. Cov khoom siv sib npaug: Cov khoom tsis yog -kev taw qhia ntawm cov iav fibers ua rau muaj kev sib txawv ntawm kev ntxhov siab, ua rau cov khoom muaj kev cuam tshuam zoo heev, khoov tsis kam, thiab qaug zog, ua tau raws li qhov yuav tsum tau muaj lub zog ntawm cov qauv tsheb thiab lub cev.

2. Ceev Impregnation thiab High Production Efficiency: Lub lev muaj qhov loj me me, zoo sib xws nrog polyester thiab epoxy resins, impregnation ceev, thiab ob peb cua npuas, ua rau nws tsim nyog rau ntau yam txheej txheem xws li molding, tes nteg- nce, thiab txhaj tshuaj molding, thiab adaptable rau automotive sib dhos kab ntau lawm {{Smooth}} textures, tso cai rau kev pleev xim ncaj qha, txheej, thiab lwm yam kev tshaj tawm - ua, ua rau muaj qhov zoo tshaj plaws.

4. Dimensional Stability thiab Resistance to Deformation: Qhov loj me me hloov pauv tshwm sim nyob rau hauv qhov kub thiab txias, tsis tshua muaj kub, thiab cov av noo siab, kom ntseeg tau tias cov khoom siv hauv tsheb tsis txhob sib tsoo lossis tawg thaum lub sij hawm siv ntev -.

5. Tus nqi zoo heev-Kev ua tau zoo: Piv rau kev xav tsis tu ncua, kev sib xyaw ua ke, thiab cov pa roj carbon fiber ntau, chopped strand lev yog tus nqi ntau dua - ua tau zoo thiab yooj yim rau scale, ua rau nws yog ib qho kev xaiv zoo rau cov neeg tsim tsheb nrhiav kev txo nqi thiab kev txhim kho kev ua haujlwm.

 

III. Core Application Scenarios of Fiberglass Chopped Straight Mat hauv Tsheb

 

Nrog rau kev siv cov ntaub ntawv sib xyaw ua ke hauv tsheb, daim ntawv thov fiberglass chopped strand lev tau nthuav dav los ntawm sab hauv thiab sab nrauv trim qhov chaw mus rau qhov chaw ua haujlwm, npog ntau yam xws li cov neeg caij tsheb, tsheb ua lag luam, thiab lub zog tshiab.

 

1. Automotive Sab hauv thiab sab nrauv Trim Parts

 

Qhov no yog ib qho ntawm cov neeg paub tab thiab siv dav siv rau kev sib tw strand lev.

- Qhov rooj sab hauv vaj huam sib luag, ncej thaiv, dashboard ncej;

- Lub rooj zaum rov qab, lub hnub visors, lub hau npog, lub log tsheb seem;

- Lub cav hood, roj teeb npog, ntau yam npog npog.

 

Siv cov khoom siv sib xyaw ua ke ntawm cov khoom siv sib xyaw ua ke tuaj yeem ua tiav qhov hnyav ntawm 20% ~ 40%, thaum muab lub suab zoo dua, rwb thaiv tsev kub, thiab kev poob siab, yog li txhim kho kev tsav tsheb.

 

2. Lub Cev Vaj Huam Sib Luag thiab Cov Txheej Txheem Txheej Txheem

 

Choped strand lev kuj tsim nyog rau thaj chaw uas xav tau ntau zog thiab rigidity:

- Pem hauv ntej thiab nram qab bumper ncej, spoiler, fairings;

- Fenders, hood, roj teeb pob hauv qab tiv thaiv lub cev;

- Cab ru tsev, sab vaj huam sib luag, av nkos, thiab lwm yam rau cov tsheb lag luam.

 

Cov khoom sib xyaw ua ke muaj kev cuam tshuam -tiv taus, khawb- tiv taus, thiab xeb- tiv taus, ua rau txo nqi kho tom qab kev sib tsoo thiab lub neej siab dua- lub voj voog tus nqi.

 

3. Cov Ntsiab Lus Tseem Ceeb rau Cov Tsheb Hluav Taws Xob Tshiab

 

Cov tsheb fais fab tshiab muaj qhov xav tau ceev dua rau lub teeb yuag, ua rau muaj kev loj hlob tawg hauv kev siv chopped strand lev (CSM).

- Cov khoom siv roj teeb, npog, thiab daim hlau tiv thaiv;

- Rwb thaiv tsev thiab hluav taws xob rwb thaiv tsev rau cov motors thiab hluav taws xob tswj tshuab;

- Them chaw nres nkoj npog thiab siab -voltage tivthaiv npog.

 

Fiberglass tsis yog -conductive, tshav kub-insulating, nplaim taws-retardant, thiab siab- zog, zoo txhim kho cov roj teeb pob kev nyab xeeb thiab kev ntseeg siab, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau lub teeb yuag lub zog tshiab.

 

4. Automotive Chassis thiab cov khoom siv ua haujlwm

 

Hauv cov cheeb tsam uas nyuaj thiab xav tau chassis ib puag ncig:

- Chassis tiv thaiv daim hlau, tiv thaiv tshav kub, thiab cov yeeb nkab tso cua sov rwb thaiv tsev;

- Ntxuam hniav, lub tshuab lim cua, thiab cov kav dej, thiab lwm yam.

 

Fiberglass CSM cov khoom muaj siab -kub resistant, corrosion{1}}resistant, thiab tiv thaiv - laus, tso cai rau lub sij hawm ntev - kev ua haujlwm ruaj khov thiab txuas ntxiv kev ua neej ntev.

 

IV. Yav tom ntej Trends: Chopped Strand Mat yuav txuas ntxiv mus tob rau nws lub luag haujlwm hauv Automotive Lightweighting

 

Nyob rau hauv lub xyoo tom ntej, kev lag luam tsheb yuav pom peb qhov tseem ceeb uas yuav tau txais txiaj ntsig ncaj qha rau txoj kev loj hlob ntawm chopped strand lev (CSM):

 

1. Kev nkag mus ntawm lub zog tshiab tsheb yuav nce ntxiv, ua rau muaj kev xav tau ntawm cov khoom siv sib xyaw rau cov roj teeb thiab cov khoom siv lub cev;

2. Kev tswj hwm ib puag ncig thiab kev siv hluav taws xob rau lub tsheb yuav dhau los ua nruj dua, ua kom lub teeb hnyav raws li tus qauv xav tau;

3. Cov txheej txheem tsim cov khoom siv sib xyaw yuav txuas ntxiv mus ntxiv, nrog rau kev siv dav dav ntawm cov kab ntau lawm xws li molding, RTM, thiab winding, uas ua rau muaj kev ua tau zoo dua thiab qis dua rau cov khoom siv strand lev.

 

Nyob rau tib lub sijhawm, nrog kev nthuav qhia tas mus li ntawm cov khoom tshiab xws li siab - kev ua tau zoo binders, ultrafine iav fibers, qis -fuzz, thiab siab -permeability tws strand lev, tws strand lev yuav hloov mus rau ntau dua lub zog, qis dua ntom ntom, ntau dua ib puag ncig tus phooj ywg, thiab zoo dua cov khoom siv ntxiv rau cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob zoo dua qub. siab - nqi sib tw alloys. Los ntawm cov tsheb roj av mus rau lub zog tshiab tsheb, los ntawm cov cuab yeej thauj mus los mus rau qhov chaw ntse mobile, txhua qhov kev txhim kho hauv kev lag luam tsheb yog sib cais los ntawm cov khoom siv tshiab.
