Yuav ua li cas xaiv high - zoo fiberglass lev thaum tsim fiberglass nuv ntses nkoj?

Xaiv txoj caifiberglasssubstrate yuav tsum nkag siab txog nws qhov zoo thiab qhov tsis zoo thiab nws qhov haum. Hauv qab no yog qee qhov kev xaiv dav dav, tab sis hauv kev xyaum, resin wetting zog kuj ua lub luag haujlwm. Yog li ntawd, txoj hauv kev zoo tshaj plaws yog ua qhov kev ntsuam xyuas ntub dej ntawm lub chaw nres nkoj fiberglass kom paub meej tias nws tsim nyog.

Ua ntej, rau fiberglass tws strand lev siv nyob rau hauv shipbuilding, qhov tseem ceeb tshaj yuav tsum tau muaj ntawv pov thawj los ntawm Tuam Tshoj Classification Society (CCS) (mainland Tuam Tshoj) thiab Lloyd's Register thiab Det Norske Veritas (DNV) (national lees paub). Muaj ntau daim ntawv pov thawj ib txhij yog qhov pov thawj zoo tshaj plaws.

Thib ob, fiberglass lev feem ntau yog siv rau phau ntawv lamination molding. Feem ntau, cov khoom lag luam zoo yuav tsum ua raws li cov hauv qab no: ① Uniform hnyav ib chav tsev. Cov xwm txheej no tseem ceeb heev, vim nws cuam tshuam rau ob qho tib si thickness thiab lub zog. Nws yooj yim dua los txheeb xyuas hauv qab lub teeb; cov khoom tsis sib xws hnyav yog pom ntawm qhov muag liab qab. Hais txog thickness uniformity, uniform hnyav ib chav tsev cheeb tsam tsis tas yuav lav uniform thickness; qhov no yog ncaj qha ntsig txog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov xovxwm txias. Cov lev tuab tsis sib xws ua rau cov ntsiab lus tsis sib xws hauv FRP cov khoom, thiab cov ntaub ntawv fluffy absorbs ntau resin. Txoj kev ntsuas tus qauv rau qhov sib xws ntawm cov ntaub ntawv loj hauv ib cheeb tsam yog txiav 300mm x 300mm cov nplooj ntawv raws li qhov dav ntawm qhov xav tau, suav lawv ua ntu zus, ntsuas lawv cais, thiab xam qhov hnyav sib txawv ntawm txhua daim ntawv xav tau.

② Uniform yarn faib, tsis muaj ntau dhau hauv zos tsub zuj zuj. Qhov sib tsoo thiab tawg qhov xwm txheej ntawm cov xov paj raw yog qhov tseem ceeb hauv kev tsim cov xov paj raw, cuam tshuam rau qhov sib xws ntawm kev xav ntawm ib cheeb tsam thiab kev faib tawm ntawm cov xov paj raw ntawm qhov xav tau. Tom qab cov xov paj nyoos ntawm cov xov paj bobbin (ncuav mog qab zib) raug txiav, txhua pob ntawm cov xov paj nyoos yuav tsum tau tawg tag nrho. Yog tias qee cov xov paj nyoos tsis tawg tag nrho, lawv yooj yim ua daim ntawv -zoo li cov kab txaij ntxhib ntawm qhov xav.

③ Tsis muaj xov paj los yog sib cais ntawm cov txheej sab hauv thiab sab nrauv. Mechanical tensile lub zog ntawm cov ntaub ntawv. Tsawg mechanical tensile lub zog ntawm cov kev xav qhia tias tsis zoo adhesion ntawm cov xov paj raw bundles.

④ Dawb los ntawm av.

⑤ Qhuav kom qhuav. Yog tias damp, nws yuav poob sib nrug thaum nthuav tawm thiab khaws dua. Cov dej noo ntawm cov ntaub ntawv yog<0.2%, which is generally acceptable for normal production processes.

⑥ Cov resin yog tag nrho impregnated. Styrene solubility. Qhov zoo tshaj plaws, kev solubility ntawm cov kev xav hauv polyester resin yuav tsum tau sim, tab sis qhov no yog lub sij hawm -siv thiab nyuaj rau kom muaj nuj nqis. Siv styrene es tsis txhob ntawm polyester cob los ntsuam xyuas cov solubility ntawm lub siab tuaj yeem cuam tshuam qhov solubility ntawm fiberglass xav hauv polyester, thiab txoj kev no tau txais thoob ntiaj teb thiab tau ua qauv.

⑦ Tsis txhob xoob ntawm cov xov paj tom qab resin impregnation.

⑧ Yooj yim defoaming.
