Fiberglass yog ib hom yas uas tau pleev xim nrog cov iav me me rau kev txhawb nqa (nws kuj tseem hu ua GRP, rau iav-yas ntxiv yas). Fiberglass yog lub teeb yuag, muaj zog nyob rau hauv ob qho tib si nrawm thiab nrawm, thiab yooj yim tuaj pwm rau hauv cov duab sib dhos. Nws tau xub qhia ua ntej hauv kev lag luam dav hlau, thiab txij li tau txais kev lees paub dav dav raws li cov khoom siv rau lub nkoj hulls, lub cev tsheb, thiab txawm tias kev tsim vaj tsev nyob. Cov khoom tshwj xeeb ntawm fiberglass ua rau nws nyuaj me ntsis rau cov xuab zeb rau hauv cov duab, thiab kawm paub yuav ua li cas cov xuab zeb fiberglass xav tau ntau qhov kev npaj ua haujlwm thiab ua siab ntev.
Cov kauj ruam
Kauj Ruam 1. Cia cov iav fiberglass kho nyob hauv lub hnub
Yog tias koj tab tom ua haujlwm nrog cov khoom siv fiberglass tshiab, nws yuav muaj txheej tuab ntawm cov kua nplaum rau ntawm nws saum npoo. Gelcoat yog ib qho epoxy lossis resin-based compound uas yog siv los kab cov pwm thaum ua cov khoom siv fiberglass. Ua ntej sanding, cia cov fiberglass zaum tawm hauv lub hnub rau 2 txog 7 hnub los kho cov gelcoat. Cov txheej txheem no tso tawm txhua lub hnab cua los ntawm cov gelcoat uas yuav ua teeb meem thaum txhuam thiab pleev xim.
Kauj Ruam 2. Sib sau cov khoom siv fiberglass, yog tias tsim nyog
Yog tias koj txoj haujlwm muaj ntau yam khoom siv fiberglass (zoo li lub cev, lub qhov rooj, thiab lub hood ntawm lub tsheb), sib sau ua ke ua ntej txhawm rau txhuam lossis ua kom tiav. Qhov no yuav tso cai rau koj ua cov xuab zeb tsis tu ncua ntawm txhua feem, tsim kom du, sib koom ua ke.
Kauj Ruam 3. Ntxuav tag nrho cov iav fiberglass nrog cov ciab thiab cov roj tshem tawm
Siv cov khoom no yog qhov tshwj xeeb tshaj yog thaum ua haujlwm nrog cov iav fiberglass tshiab, vim tias nws yog qhov tsim nyog kom tshem tawm tus neeg sawv cev tso tawm, cov khoom siv los txhuam cov khoom xoob los ntawm nws cov pwm. Ciab thiab tshem tawm cov roj tuaj yeem yuav los ntawm cov khw muag khoom tsheb.
Kauj Ruam 4. Xuab zeb fiberglass siv cov ntawv xuab zeb ntxhib
Rau thawj daim ntawv hla, siv 80 lossis 100-grit cov ntawv txhuam. Nthuav cov ntawv xuab zeb mus rau daim txiag zeb ntev ntev rau cov khoom loj, tiaj tus. Rau thaj chaw me me lossis thaj chaw uas muaj txoj kab nkhaus tsis sib xws, cov roj hmab xuab zeb thaiv ua haujlwm tau zoo ua raws cov duab ntawm daim.
- Tsis txhob txhuam txhua txoj hauv kev hla cov gelcoat mus rau hauv fiberglass nws tus kheej. Qhov no ua rau 2 teeb meem: nws ua rau lub zog tsis muaj zog ntawm cov khoom siv, thiab nws tsim qhov nyob hauv cov iav fiber uas tso cai rau nws tawg los ntawm cov xim tom qab.
- Cov kua nplaum tuaj yeem siv ua cov lus qhia thaum lub sijhawm pib xuab zeb. Sanding cov gelcoat tsuas yog txaus yuav ua rau nws lub ntsej muag npub, yog li thaum tag nrho cov tivthaiv tau ploj nws qhov ci, koj tau xuab zeb txaus kom tso cai primer lossis pleev xim kom ua raws.
Kauj Ruam 5. Sau cov pob qis hauv cov iav fiberglass
Txhawm rau nce qhov profile ntawm qhov chaw qis hauv qhov chaw, siv cov iav fiberglass glaze putty. Ua haujlwm tso rau hauv qhov chaw qis, thiab tom qab ntawd muab nws pov tseg kom txog thaum thaj tsam tau yaug nrog cov av tas.
Kauj Ruam 6. Thov primer rau cov iav fiberglass
Thaum cov khoom tiv thaiv tau xuab zeb nrog cov xuab zeb ntxhib-ntxhib, thov siv cov primer thiab tso cai rau nws teeb tsa. Tsis txhob siv cov tshuaj pleev xim ua ntej, vim nws yuav tsis ua zoo rau fiberglass.
Kauj Ruam 7. Xuab zeb ua tiav nrog siv cov xuab zeb nplua
Tom qab txheej txheej tau teeb tsa, xuab zeb tag nrho cov khoom siv ntxiv nrog cov ntawv nplua-nplua xws li 180 lossis 220-grit. Tom qab ua cov xuab zeb no, txuas ntxiv thov ua ntej lossis pleev xim raws li qhov xav tau, txhuam ntawm txhua daim ntawv thov nrog cov ntawv nplua-nplua.
