Yog tias koj xav txo qhov teeb meem ntawm gelcoat, nws yog ib qho tseem ceeb heev uas yuav tsum tau ua tib zoo saib ntawm cov kev paub ntawm qee cov neeg uas tau nyob ntawd, thiab sau cov ntsiab lus ua thiab tsis ua.
Xav ua
Tsim kom muaj hom gelcoat kom raug ua ntej pib ua hauj lwm, xyuas kom meej thiab meej pwm npaj rau siv, thiab do txhua lub nruas kom huv si tab sis maj mam (kom tiv thaiv huab cua los ntawm kev ntxiab).Ua ntej pib, xyuas kom cov gelcoat thiab pwm nyob ntawm qhov kub ntawm 16-30 ° C. Qhov zoo tshaj plaws, pwm kub yuav tsum yog 2-3 ° C siab tshaj qhov kub ntawm gelcoat.Nws mam li pib kho ntawm kev sib cuag, ua rau saum npoo smoother.
Khaws qhov txheeb ze av noo qis dua 8O%.Txawm tias nyob rau qhov kub siab, qhov siab dua ntawm cov dej vapor hauv thaj chaw ua haujlwm tuaj yeem ua rau tsis txaus kho.Nws tseem yog ib qho tseem ceeb los tiv thaiv cov dej los ntawm condensing rau saum npoo ntawm pwm.
Xyuas kom meej tias cov pwm saum npoo raug kho zoo nrog tus neeg tso tawm.Tsis txhob siv cov tshuaj silicone tso tawm.Cov khoom siv dej yuav tsum tau qhuav tag ua ntej siv gelcoat.Gelcoat tuaj yeem siv tam sim ntawd.Tsis txhob ntxiv cov kuab tshuaj xws li acetone.Styrene mus txog 2% Tej zaum yuav ntxiv yog tias daim ntawv thov yuav tsum muaj viscosity qis dua.
Cov ntsiab lus catalytic ntawm MEKP yog 2%.Yog tias cov ntsiab lus catalyst siab dhau lossis qis dhau, kev kho tsis txaus yuav txo cov huab cua tsis kam thiab dej tsis kam ntawm gelcoat.
Yog hais tias pigment ntxiv, xyuas kom meej xim ceev thiab compatibility ua ntej siv.Ntxiv tus nqi pom zoo ntawm cov xim, ua kom raug hnyav thiab sib tov siv cov khoom siv qis qis.
Thaum txau, lub thickness yuav tsum tau nce mus rau qhov xav tau nyob rau hauv 3 lub sij hawm los tso cov npuas zoo.
Yog tias gelcoat tau txau, nco ntsoov siv cov gel txheej sib npaug ntawm 400 txog 600 microns (sib npaug rau 550-700 grams ib square meter) siv qhov tseeb nozzle qhov chaw thiab tshuaj tsuag siab thiab nrug.Gelcoat nrog me me thickness yuav tsis kho zoo txaus, thaum gelcoat nrog ib tug loj thickness yuav khiav, tawg thiab tsim pores.Siv lub ntsuas ntsuas los kuaj xyuas qhov tseeb tuab thiab xyuas kom cov pwm muaj qhov cua zoo.Styrene monomer vapor yuav tiv thaiv polymerization thiab vim nws qhov tshwj xeeb lub ntiajteb txawj nqus yuav nyob twj ywm hauv qis ntawm cov pwm sai li sai tau thaum cov gelcoat tau kho tag nrho (ib zaj duab xis nruj, tab sis xav tias nplaum), cov txheej txheem seem yog siv.
Tsis txhob
Tsis txhob tso cua ntau dhau thaum lub sijhawm catalyst thiab pigment sib xyaw
Tsis txhob siv cov khoom sib tov sib xyaw ua ke, uas yuav ua rau muaj kev puas tsuaj thixotropic, pigment sib cais / flocculation, kua thiab cua nkag.
Tsis txhob dilute gelcoat nrog cov kuab tshuaj uas tsis yog styrene monomer.Thaum ntxiv styrene, cov ntsiab lus siab tshaj plaws yuav tsum tsis pub tshaj 2%.
Tsis txhob ncuav gelcoat ncaj qha mus rau pwm ua ntej txhuam hniav (qhov no yuav tsim cov duab ntxoov ntxoo).
Tsis txhob siv gel lub sij hawm sai heev, qhov no tsis cia cov huab cua seem khiav tawm.
Tsis txhob siv dhau los yog hauv qab catalyst lossis pigment.
Tsis txhob siv silicone wax vim lawv tuaj yeem ua rau ntses qhov muag.
Hais txog peb
Hebei Yuniu Fiberglass Manufacturing Co., Ltd.Peb tsuas yog tsim thiab muag e-hom fiberglass khoom, xws li fiberglass roving, fiberglass tws silk, fiberglass tws xav, fiberglass gingham, koob xav, fiberglass ntaub thiab hais txog.Yog hais tias muaj kev xav tau, thov hu rau peb dawb do.
Cov lus qhia rau cov khoom pwm loj
Vim yog tus nqi siab koom nrog gel txheej ntawm cov pwm loj xws li lub nkoj hulls thiab decks, nws raug nquahu kom tsim khoom nrog ntau qhov loj txaus uas tau ua ntej sib xyaw los ntawm cov chaw tsim khoom vim tias cov xim yog hauv av ncaj qha rau hauv gel txheej thaum tswj. ntau lawm.
Txawm li cas los xij, siv cov khoom siv tib yam (xws li thawj laminate, catalyst ntau npaum li cas, sib xyaw kos duab, rhiav thiab tus neeg teb xov tooj) yuav tsum tau siv los tsim cov khoom siv me me ua ntej pib tsim pwm.Qhov saum npoo tuaj yeem raug tshuaj xyuas rau qhov tsis xws luag thiab nto gelcoat hardness kuaj siv Barcol meter ua ntej pib tsim khoom.
