Dab tsi ntawm cov khoom siv fiberglass yog siv rau lub hauv paus ntawm lub dab da dej thiab da dej enclosures?

Hauv kev sib koom ua ke hauv chav da dej, cov haujlwm hauv tsev so, thiab kev kho kom zoo nkauj hauv tsev, cov dab da dej thiab da dej hauv qhov chaw ua los ntawm fiberglass tau dhau los ua cov khoom tseem ceeb. Lawv yog lub teeb yuag, siab -lub zog, dej tsis qab thiab mildew- pov thawj, leak- pov thawj nrog ib qho - daim molding, thiab muaj kev ywj pheej ntawm kev tsim qauv. Cov txiaj ntsig zoo no txhua tus vam khom rau cov khoom siv tseem ceeb ntxiv -fiberglass khoom.

 

Ntau tus neeg tuaj tshiab rau hauv kev lag luam, cov tuam txhab, cov neeg yuav khoom, thiab cov kws tshaj lij nug: Lub hauv paus zoo li nws tsuas yog txheej ntawm fiberglass thiab ib txheej ntawm resin, tab sis hom fiberglass yuav tsum siv li cas? Xav los yog ntaub? Puas yog txhais tes nteg- nce thiab molding cov ntaub ntawv tib yam?

 

Tsab ntawv xov xwm no yuav piav qhia meej txog cov khoom siv fiberglass uas nquag siv rau hauv chav da dej thiab da dej hauv lub hauv paus hauv kev ua tau zoo thiab yooj yim -kom- nkag siab txoj hauv kev, tso cai rau cov chaw tsim khoom ncaj qha xa mus rau cov khoom xaiv.

 

I.Fiberglass Chopped Strand Mat: Cov Core thiab feem ntau siv fiberglass khoom rau hauv paus

 

Txawm hais tias nws yog lub hauv paus da dej tsis tu ncua lossis tus qauv da dej hauv lub hauv paus, chopped strand lev yog cov khoom siv tseem ceeb, suav txog ntau dua 70% ntawm tag nrho cov fiberglass siv.

Chopted strand lev muab faib ua ob hom: hmoov lev thiab emulsion lev. Powdered xav tau nkag mus sai sai thiab muaj tus nqi qis, ua rau nws tsim nyog rau kev tsim khoom loj ntawm cov txheej txheem basins. Emulsion muaj kev ywj pheej zoo dua thiab zoo heev moldability, thiab tsis tshua muaj cov kab dawb, cov streaks qhuav, thiab npuas, ua rau nws tsim nyog rau txoj kev nkhaus, qhov tob tob, thiab siab - zoo basins.

Kev lag luam hnyav hnyav yog 300g / ㎡ thiab 450g / ㎡, siv ua ke nyob ntawm lub phiab lub thickness thiab lub zog xav tau. Lub luag hauj lwm ntawm chopped strand lev yog los xyuas kom meej ib tug uniform tag nrho cov qauv, txaus toughness, thiab tej yam kuj, guaranteeing lub phiab yuav tsis tawg los yog deform nyob rau hauv ntev -lub sij hawm load- bearing thiab alternating kub thiab txias kub. Nws tuaj yeem hais tau tias tsis muaj cov hlua khi hlua khi, yuav tsis muaj qhov ruaj khov thiab ruaj khov FRP chav dej phiab.

 

II. Fiberglass woven npuag: Qhov tseem ceeb rau thaj chaw muaj zog thiab tiv thaiv tawg

 

Ntau tus neeg ntseeg tias kev xav tau txaus rau cov phiab, tab sis qhov tseeb, cov ntaub npuag yog tus yuam sij rau kev txiav txim siab ntawm lub phiab qhov ruaj khov. Fiberglass reinforcing npuag muaj zog thiab muaj zog zoo, feem ntau yog siv ntawm cov ntsiab lus kev ntxhov siab hauv lub dab da dej:

- Lub hauv qab reinforcing tav

- Nyob ib ncig ntawm lub qhov hluav taws xob

- Ntug ntug ntawm lub tub

- Cov cheeb tsam ntawm kaum tsev muaj kev cuam tshuam thiab kev ntxhov siab

Cov kev qhia tshwj xeeb yog 200g / ㎡ thiab 400g / ㎡. Nws siv cov qauv "felt + npuag" cov qauv sib xyaw, uas txhim kho qhov tensile thiab qaug zog tiv thaiv ntawm lub dab da dej, tiv thaiv kev tawg, tawg, thiab tawg tom qab siv ob peb xyoos.

Rau thickened, engineering-qib da dej, fiberglass reinforcing ntaub yog ib qho tseem ceeb cov khoom siv ntxiv.

 

III. Surface Felt: Ib "Cov Khoom Siv Lub ntsej muag" txhawm rau txhim kho qhov tshwm sim thiab tshem tawm cov pinholes

 

High-cov dab da dej thiab cov tais da dej zoo muaj qhov du, pinhole-dawb nto nrog ib qho kev ntxhib los mos. Cov nyhuv no tso siab ntau rau ntawm fiberglass nto hnov.

Nto xav yog qhov hnyav heev, feem ntau 30g / ㎡ thiab 50g / ㎡, nrog kev ntxhib los mos, tshwj xeeb nteg nruab nrab ntawm gel txheej txheej thiab txheej txheej txheej.

Nws cov haujlwm yog qhov tseem ceeb:

- Ncua lub hauv paus fiberglass kev ntxhib los mos, ua rau lub ntsej muag smoother.

- Txo cov pinholes, npuas, thiab txiv kab ntxwv tev nyhuv.

- Txhim kho gel tsho tiv no adhesion, ncua lifespan.

- Ua kom lub phiab yooj yim los ntxuav thiab tsis tshua muaj xim daj.

Cov phiab uas tsis muaj qhov xav tau muaj qhov zoo li ntxhib thiab ntau qhov tsis zoo, faib lawv raws li qis- cov khoom kawg; siv lub ntsej muag zoo yog qhov tseem ceeb rau kev ua tiav siab - qhov kawg ntawm chav dej.

 

IV. SMC Moulding Compound: Cov Khoom Siv Tshwj Xeeb rau Siab -Tag Nrho Cov Da Dej

 

Cov chav da dej sib xyaw ua ke thiab siab - lub zog da dej hauv tsev siv dav hauv cov tsev so thiab cov phiaj xwm vaj tsev tam sim no yuav luag tsuas yog siv SMC molding tshuab.

SMC yog ib daim ntawv molding compound muaj li ntawm alkali-dawb tws fiberglass yarn, resin, fillers, thiab lwm yam. Nws cov ntsiab lus fiberglass siab ua rau siab ceev, siab zog, thiab txaus rigidity tom qab molding. Seamless ib -daim molding tag daws cov teeb meem to.

SMC basins muaj kev ua haujlwm siab, kev laus ua haujlwm, thiab kev cuam tshuam tsis zoo, nrog rau kev ua neej ntev tshaj 20 xyoo. Nws yog ib yam khoom siv rau siab - chav dej kawg thiab sawv cev rau txoj kev loj hlob ntawm lub hauv paus rau hauv chav dej yav tom ntej.

 

V. Untwisted roving: Rau kev txhawb nqa thiab kev txhawb zog hauv zos

 

Untwisted fiberglass roving yog siv nyob rau hauv ib co thickened bass thiab cov khoom uas muaj siab - zog txhawb ob txhais ceg. Nws yog tsuas yog siv rau wrapping reinforcing tav, localized thickening, thiab kho puas. Nws muaj lub zog siab thiab nruab nrab cov kua nplaum nqus, ua rau cov ntsiab lus tseem ceeb ntawm kev ntxhov siab muaj zog thiab txhim kho tag nrho kev ruaj ntseg ntawm lub phiab. Txawm hais tias tus nqi siv tsis yog loj npaum li chopped strand lev, nws yog ib qho tseem ceeb ntxiv los txhim kho kev ruaj ntseg ntawm cov qauv.

 

VI. Xaiv cov ntaub ntawv zoo yog ib nrab ntawm kev sib ntaus sib tua yeej rau lub phiab ua tiav.

 

Fiberglass yog "skeleton" ntawm chav da dej. Xaiv cov pob txha zoo thiab ruaj khov yog qhov tseem ceeb rau cov khoom ruaj khov thiab ua tiav.

Chopted strand lev yog lub luag haujlwm rau tag nrho cov qauv, woven npuag rau kev txhawb nqa thiab kev tiv thaiv tawg, nto zoo rau cov tsos zoo, thiab SMC rau siab -kawg molding- txhua ntawm plaub cov ntaub ntawv no ua lub luag haujlwm tshwj xeeb. Kev sib xyaw kom zoo ua rau hauv chav dej hauv chav dej uas tawg -dawb, xau- pov thawj, deformation- tiv taus, thiab ua kom zoo nkauj. Txawm hais tias koj yog cov chaw tsim khoom, tus kws tshaj lij, tus neeg yuav khoom, lossis tus xa khoom, kev nkag siab cov ntaub ntawv fiberglass no yuav pab koj kom tsis txhob muaj kev cuam tshuam thiab kev cuam tshuam hauv kev tsim khoom, xaiv cov khoom siv, thiab kev tswj kom zoo.
