Cov ntsiab lus tseem ceeb rau xaiv Fiberglass Cloth Thiab Fiberglass Mat

Basic Material Analysis:

 

1. Alkali-dawb fiberglass lev, tseem hu ua alkali-dawb tws strand lev, yog tsim los ntawm kev txiav fiberglass yarn rau hauv ruaj - ntev fibers. Cov fibers no mam li muab tso rau ntawm ib txoj siv conveyor siv cov khoom siv, sib txuas thiab kho nrog cov hmoov los yog emulsion binders, thiab thaum kawg qhuav, txias, thiab qhov txhab. Feem ntau specifications rau fiberglass nuv ntses nkoj muaj xws li:

 

EMC300-1040 (300g / ㎡, 1040mm dav)

 

EMC450-1040 (450g / ㎡, 1040mm dav)

 

EMC600-1040 (600g / ㎡, 1040mm dav)

 

2. Fiberglass daim ntaub, tseem hu ua untwisted fiberglass roving, yog tsim los ntawm interlacing untwisted rovings nyob rau hauv warp thiab weft cov lus qhia raws li ib tug tshwj xeeb qauv. Thaum woven siv nruam ib leeg -strand untwisted fiberglass roving (direct yarn), lub resulting woven fabric yog untwisted roving ntaub, feem ntau hu ua checkered daim ntaub. Cov kev qhia tshwj xeeb rau kev tsim nkoj nuv ntses yog:

EWR400-1040 (400g / ㎡, 1000mm dav)

EWR600-1040 (600g / ㎡, 1000mm dav)

EWR800-1040 (800g / ㎡, 1000mm dav)

 

Ob hom ntaub ntawv no zoo li yooj yim, tab sis muaj ntau yam intricacies. Peb yuav txheeb xyuas lawv los ntawm peb qhov tseem ceeb:

Ib. Khob Fiber Composition

Raws li "Specifications for the Construction of Fiber Reinforced Plastics for Fishing Boats," fiberglass nkoj tsim yuav tsum siv alkali-dawb iav fiber ntau (sodium oxide cov ntsiab lus<0.8%). Medium-alkali products have poor corrosion resistance and are prone to alkali precipitation after prolonged immersion in water [leading to embrittlement of the laminates], and are strictly prohibited from use in hull construction.

 

2. Cov txheej txheem tsim khoom tam sim no

 

Cov txheej txheem kev tsim khoom tseem ceeb tau muab faib ua ob lub tshuab loj: lub tshuab hluav taws xob hluav taws xob kos duab (sau ntau dua 95%) thiab kos duab crucible.

 

• Tank furnace drawing: Siv platinum spindles rau kev kos duab ncaj qha, ua tiav kev tsim khoom tas li los ntawm cov khoom siv raw melting mus rau kos duab. Nws boasts qhov zoo xws li lub peev xwm siab (txog 100,000 tons ib kiln ib xyoos), kev siv hluav taws xob tsawg (ntau zog-ntau dua li cov txheej txheem crucible), thiab ruaj khov zoo (yarn tex tus nqi hloov pauv < ± 3%).

 

• Crucible kos duab: Ib txheej txheem melting thib ob, nws raug kev txom nyem los ntawm kev siv hluav taws xob siab thiab cov khoom siv tsis zoo, thiab tam sim no tsis siv ntau lawm.

 

3. Chaw tsim tshuaj paus Tier System Domestic

 

Cov neeg tsim khoom nthuav tawm cov kev faib tawm meej, tsim "ib lub zog loj thiab ob tus neeg muaj zog" tus qauv: Tuam Tshoj Jushi (27% kev lag luam thoob ntiaj teb), Taishan Fiberglass, thiab Chongqing International, peb lub tuam txhab loj, sib sau ua ke tswj kwv yees li 45% ntawm lub ntiaj teb kev tsim khoom.

 

Tam sim no, alkali-dawb fiberglass roving thiab alkali-dawb chopped strand lev muab rau lub lag luam hauv tsev feem ntau yog los ntawm peb hom kev lag luam hauv qab no:

 

1. Reputable furnace manufacturers uas tsim lawv tus kheej reinforcing cov ntaub ntawv (daim ntaub / lev), siv cov txheej txheem ntau lawm tswj systems. Lawv cov khoom tau lees paub los ntawm cov koom haum kev faib tawm xws li DNV-GL thiab CCS. Cov khoom lag luam los ntawm "Ib Super thiab Ob Lub Zog" cov chaw tsim khoom, tshwj xeeb, yog qhov ruaj khov thiab lav zoo, thiab tuaj yeem yuav nrog kev ntseeg siab!

 

2. Loj thiab nruab nrab - fiberglass woven fabric processing nroj tsuag nrog tej yam kev muaj peev xwm. Cov chaw tsim khoom no feem ntau yuav cov khoom siv raw los ntawm cov chaw tsim khoom siv hluav taws xob rau kev ua haujlwm thib ob. Txawm hais tias cov khoom lag luam ruaj khov tuaj yeem hloov pauv vim qhov sib txawv ntawm cov khoom siv raw, qhov zoo ntawm cov khoom siv raw yog feem ntau lav. [Nws raug pom zoo kom tsom mus rau kev ruaj ntseg ntawm lawv cov khoom siv raw khoom thiab lawv cov txheej txheem tswj kev muaj peev xwm].

 

3. Me me thiab micro- cov chaw ua haujlwm loj nrog ntau qib kev sib txawv. Txhawm rau txo cov nqi, lawv feem ntau sib tov thiab siv thib ob -qib / cov khoom tsis raug los ntawm cov tuam txhab tsim hluav taws xob. [Ib txhia txawm tias tsis raug cai ntxiv cov khoom siv pov tseg rov qab los yog nruab nrab- rau- cov khoom siv alkali siab]. Xws li "kev sib xyaw" cov khoom lag luam muaj qhov tsis sib xws ntawm impregnation thiab hloov pauv hauv lub zog tensile, ncaj qha cuam tshuam rau lub zog interlayer shear zog thiab qaug zog tiv thaiv ntawm fiberglass nuv ntses nkoj. Kev sim cov ntaub ntawv qhia tau hais tias lub zog txo tus nqi ntawm qhov tseem ceeb ntawm lub nkoj lub nkoj siv cov ntaub ntawv tsis zoo tuaj yeem yog 3-5 npaug ntawm cov khoom tiag.

 

Hauv kev lag luam chaotic ntawm alkali-dawb fiberglass, batch ntawm ze li ntawm cov khoom zoo tib yam tau tshwm sim nyob rau hauv pem hauv ntej ntawm factories, tab sis lawv cov nqi sib txawv heev. Cov ntaub ntawv tsis zoo, txhob txwm tshaj tawm kom txo tus nqi, zoo li hma hauv yaj cov khaub ncaws, ntxias cov neeg yuav khoom nrog lawv nyob ze - zoo meej. Qee cov neeg siv khoom lag luam fiberglass nkoj nkoj cov neeg yuav khoom, raug ntxias los ntawm tus nqi qis, maj nrawm kos npe rau kev txiav txim, tsis paub tias cov ntaub ntawv raw cov ntaub ntawv hauv lawv txhais tes yog ntsiag to hloov mus rau hauv cov kab nrib pleb tuag nyob rau yav tom ntej.

 

Thaum cov khoom siv fiberglass tsis zoo no tau nkag mus rau hauv cov kab ntau lawm, cov kev phom sij zais tau faus tob zoo li cov noob. Kev sib txuas ntawm cov resin thiab fiber ntau tsis muaj zog, thiab npuas sprouts zoo li anthills ua ntej lub pas dej tawg. Nyob rau hauv qhov seemingly du hull laminate, tsis sib npaug fiber ntau impregnation thaj ua rau thaj yog zoo li cov kab mob zais, rhuav tshem cov kev sib raug zoo nrog txhua qhov kev cuam tshuam. Interlaminar shear lub zog yog ploj mus imperceptibly, thiab qaug zog ua hauj lwm yuav zoo li ib tug hollowed - tawm beam - lub seemingly pristine nuv ntses nkoj yog tiag tiag ib tug zais kev phom sij suav txog hnub tom ntej.

 

Thaum cov tswv nkoj ntaus cov khoom lag luam- lub nkoj tshiab, lawv cov ntiv tes taug qab cov txheej txheem zoo kawg nkaus, tsis tuaj yeem kov cov kev ntxhov siab hauv qab groans. Txog rau ib hnub, qhov dej tsis txaus siab tau tshwm sim tam sim ntawd lub kua muag qhib cov kab nrib pleb, thiab lub zog ntawm cov txheej txheem ib zaug tau noj los ntawm cov ntaub ntawv pheej yig thaum kawg yuav dhau los ua ntshav- thiab - kua muag exclamation cim nyob rau hauv phau ntawv teev npe.
