Kev Npaj Ua Ntej- Cov Khoom Muag Khoom Muag Khoom Muag: Tshawb xyuas cov qauv khoom siv FRP, batch tooj, thiab hnub tsim khoom; paub meej tias qhov sib xws ntawm hom resin thiab tus neeg sawv cev curing; thiab tshuaj xyuas cov ntaub ntawv txhawb zog-xws li ntaub fiberglass- kom paub tseeb tias lawv qhov hnyav thiab qhov ntom ntom. Kev tsim kho ib puag ncig kub yuav tsum tau khaws cia ntawm 15℃thiab 30 degree, nrog cov av noo qis dua 80%.
Kev ua haujlwm yuav tsum raug ncua thaum lub caij ntuj nag.
Kev npaj saum npoo yog ua nyob rau hauv peb kauj ruam: ntxuav cov pob zeb lossis hlau substrate, tshem tawm cov khoom xoob, thiab txhuam cov roj stains siv acetone. Sau cov kev nyuaj siab thiab qhov tsis sib xws nrog epoxy mortar; rau cov kab nrib pleb tshaj 2 hli hauv qhov dav, txiav ib V- zawj thiab txhaj tshuaj grout. Nto flatness yuav tsum tau xyuas kom meej siv ib tug 2-meter straightedge, xyuas kom meej tias tej qhov khoob tsis pub tshaj 3 hli. Cov chaw hlau yuav tsum tau ua cov xuab zeb blasting kom ua tiav qib kev huv ntawm Sa2.5, nrog rau qhov roughness ntawm 40-70 microns. Kev txiav cov khoom: Saib Warp thiab Weft Direction. Rau daim ntaub fiberglass, tso cai rau 10 cm sib tshooj dhau ntawm qhov ntev ntawm daim ntawv thov nto; Thaum thov diagonally, txiav cov khoom ntawm lub kaum sab xis 45-degree. Cov pa roj carbon fiber ntau yuav tsum * tsis txhob folded; Thaum khaws cia, khaws cov yob sawv ntsug. Thaum thov ntau cov khaubncaws sab nraud povtseg, stagger lub seams ntawm cov khaubncaws sab nraud povtseg tsawg kawg yog 30 cm; ntawm cov ces kaum, txiav cov khoom mus rau hauv radial strips.
Resin Mixing: Ua raws li cov txheej txheem ua haujlwm nruj me ntsis. Ntsuas cov epoxy resin thiab curing tus neeg sawv cev raws li cov proportions teev nyob rau hauv lub khw cov lus qhia. Thaum sib tov, do nyob rau hauv ib tug clockwise kev taw qhia nyob rau hauv lub puab phab ntsa ntawm lub thawv los tiv thaiv kev tsim ntawm huab cua npuas. Tso tseg kev siv cov sib tov ib zaug tsuas yog ib qho -peb ntawm nws lub lauj kaub lub neej (lub sijhawm ua haujlwm) tseem nyob; hloov lub thawv sib tov nrog ib qho tshiab txhua teev. Hnav lub ntsej muag tiv thaiv lub ntsej muag thaum ntxiv cov accelerators, thiab nruj me ntsis * txwv * kev sib xyaw ntawm cov tshuaj tua kab mob los ntawm ntau hom.
Daim ntawv thov kev txhawb zog: Saib lub Sijhawm Qhov rai. Siv cov txhuam txhuam dipped hauv resin los siv cov txheej txheej ntev mus rau lub substrate nto, ces tam sim ntawd nteg cov ntaub fiber ntau. Siv cov roj hmab squeegee tshem tawm cov npuas cua, ua haujlwm ntawm qhov chaw sab nraud mus rau cov npoo. Siv ob txheej ntawm daim ntaub ua ntej txheej dhau los tau gelled. Xyuas kom meej tias txhua txheej ntawm resin kom saturates cov ntaub fiber ntau; daim ntawv thov raug suav tias ua tiav yog tias cov xim hauv qab substrate tseem pom los ntawm cov ntaub. Hauv cov cheeb tsam uas xav tau kev txhawb nqa hauv zos, siv cov ntoo khaub lig- cov khaubncaws sab nraud povtseg- tsis pub tsawg tshaj peb ntawm tag nrho.
Txoj kev kho: Phased Control. Saib xyuas lub sijhawm "tack-dawb": tsis txhob kov qhov chaw rau 3 teev nyob rau lub caij ntuj sov thiab 8 teev nyob rau lub caij ntuj no. Tsis txhob muab cov khoom siv rau cov khoom hnyav lossis dov siab ua ntej nws tau kho tag nrho. Rau peb hnub tom qab daim ntawv thov, tuav lub ambient kub tsis qis tshaj 10 degree. Siv Barcol Hardness Tester los xyuas qhov kev kho; mus rau theem tom ntej ntawm kev ua haujlwm tsuas yog tom qab tus nqi hardness nce mus txog 40 lossis siab dua.
Kev kho deg: Kev txiav txim siab txog cov khoom lag luam. Thaum kho, xuab zeb ntawm qhov chaw kom tshem tawm cov burrs los yog ntxhib pob. Siv ob lub tsho tiv no ntawm cov gelcoat, tso cai rau 12- teev nyob nruab nrab ntawm cov tsho loj. Hauv cov cheeb tsam uas muaj UV hluav taws xob hnyav... Siv cov tshuaj tiv thaiv kev laus nrog qhov tsawg kawg nkaus ntawm 200 microns. Siv lub kaum sab xis los txiav cov kav dej hauv cov cheeb tsam uas xav tau qhov dej ntws.
Kev lees txais yuav tsum siv tus qauv GB502. Kev kuaj adhesion yuav tsum yog siv tus ntoo khaub lig-txiav txoj kev; tsis pub tev tawm ntawm cov npoo ntawm qhov txiav. Kev kuaj pom tsis pom kev yuav tsum tau ua los ntawm kev sib tw nrog ib qho ntoo mallet; thaj tsam ntawm ib qho khoob khoob yuav tsum tsis pub tshaj 5 square centimeters. Thickness sib txawv yuav tsum tau tswj tsis pub dhau ± 10%. Hauv thaj chaw khoom siv hluav taws xob, TRP txheej yuav tsum dhau kev ntsuas kev tiv thaiv hluav taws xob.
Thaum lub sij hawm txij nkawm, yuav tsum tau tsim ib daim ntawv teev tseg. Thaum lub chaw muab tso rau hauv kev ua haujlwm, yuav tsum tau kuaj xyuas peb lub hlis twg, nrog rau kev saib xyuas tshwj xeeb rau kev kuaj xyuas cov kab nrib pleb ntawm cov seams thiab cov cim ntawm discoloration (daj).
Nyob rau hauv ib puag ncig uas muaj tshuaj corrosion, qhov saum npoo yuav tsum tau yaug txhua hli; cov kua qaub lossis alkaline residual yuav tsum tau nruab nrab tam sim ntawd siv cov tshuaj sodium bicarbonate. Rau kev puas tsuaj hauv cheeb tsam, ib txoj kev sib tsoo yuav tsum ua haujlwm, ua kom muaj qhov sib tshooj dav ntawm ntau dua 8 centimeters ntawm qhov chaw tshiab thiab tam sim no.
Kev nyab xeeb kab liab yuav tsum tsis txhob ua txhaum cai. Cov neeg ua haujlwm yuav tsum hnav khaub ncaws tiv thaiv - zoo li qub; Yog hais tias resin tuaj rau hauv daim tawv nqaij, nws yuav tsum tau yaug tam sim ntawd nrog xab npum thiab dej. Cov tshuaj tua kab pov tseg yuav tsum tau muab cais tawm thiab txwv nruj kom tsis txhob muab nchuav rau hauv cov kav dej lossis cov kav dej. Hnav daim npog ntsej muag thaum txiav cov ntaub fiber ntau. Qhov chaw ua haujlwm yuav tsum tau ua kom cua nkag, thiab qhov siab ntawm styrene hauv huab cua yuav tsum tsis pub tshaj 50 ppm. Cov cuab yeej insulated ntawm cov cuab yeej hluav taws xob yuav tsum tau tshuaj xyuas txhua lub lim tiam.
Kev daws teeb meem: Yog tias cov resin sagging raug pom, tam sim ntawd so nws nrog acetone. Cov nyhuv whitening tom qab kho yog suav tias yog ib qho tshwm sim. Thaum lub caij ntuj no kev tsim kho, thaum resin viscosity siab, nws yuav tsum tau sov los ntawm da dej rau 25℃ua ntej siv. Yog tias wrinkles tshwm tom qab siv daim ntaub fiber ntau, nws yuav tsum tau tev tawm thiab rov ua dua -; thov ib txheej tshiab ncaj qha hla ntu wrinkled yog nruj me ntsis txwv tsis pub. Yog tias loj - thaj tsam blistering raug tshawb pom thaum lub sij hawm lees txais kev soj ntsuam, qhov cuam tshuam yuav tsum tau txiav tawm thiab rov ua dua; localized patching tsis tso cai.
