Thaum xaiv cov fiberglass chopped strand lev zoo rau kev tsim cov nkoj nuv ntses fiberglass, nws yog ib qho tseem ceeb kom nkag siab txog nws cov txiaj ntsig thiab kev tsim nyog. Nov yog cov ntsiab lus luv luv ntawm cov qauv xaiv, tab sis nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev sib raug zoo nrog cov resin, tshwj xeeb tshaj yog hais txog kev impregnation, yog ib qho tseem ceeb. Yog li ntawd, txoj hauv kev zoo tshaj plaws yog ua qhov kev sim impregnation ntawm lub chaw tsim khoom nkoj fiberglass kom paub meej tias tsim nyog.
Tsis tas li ntawd xwb, cov fiberglass chopped strand lev feem ntau yog siv rau hauv cov txheej txheem molding tes, thiab cov khoom ua tau raws li cov xwm txheej hauv qab no feem ntau suav tias yog qhov zoo:
1. Qhov hnyav sib npaug rau ib cheeb tsam. Qhov no yog qhov tseem ceeb heev vim nws cuam tshuam rau ob qho tib si tuab thiab lub zog. Hauv qab lub teeb, nws yooj yim dua los txheeb xyuas cov khoom uas muaj qhov tsis sib xws, uas tuaj yeem pom nrog lub qhov muag liab qab. Txawm hais tias qhov sib npaug ntawm qhov hnyav ib cheeb tsam tsis lav qhov tuab sib xws - vim qhov no kuj nyob ntawm qhov sib npaug ntawm qhov sib txawv ntawm cov menyuam txias - kev hloov pauv ntawm cov tuab ntawm daim lev tuaj yeem ua rau cov ntsiab lus tsis sib xws hauv cov khoom fiberglass kawg. Daim lev uas muaj qhov hnyav sib npaug ntau dua feem ntau nqus cov resin sib npaug ntau dua. Kev xeem txheem rau kev sib npaug suav nrog kev txiav daim lev ua 300mm x 300mm daim thoob plaws nws qhov dav, suav lawv ua ntu zus, ntsuas txhua daim, thiab xam qhov sib txawv ntawm qhov hnyav.
2. Kev faib cov xov paj sib npaug yam tsis muaj kev sib sau ntau dhau hauv txhua thaj chaw. Qhov kev sib kis ntawm cov xov paj thaum lub sijhawm tsim khoom yog qhov tseem ceeb uas cuam tshuam rau qhov sib npaug ntawm qhov hnyav ntawm daim lev ib cheeb tsam thiab kev faib cov xov paj ntawm daim lev. Tom qab txiav, txhua pob xov paj yuav tsum sib kis kom huv si. Yog tias qee cov pob tsis sib kis zoo, lawv tuaj yeem tsim cov kab tuab ntawm daim lev.
3. Qhov saum npoo yuav tsum tsis txhob muaj cov dej ntws los yog cov khoom tawg. Lub zog tensile ntawm daim lev qhia txog qhov zoo ntawm kev sib txuas ntawm cov hlua khi.
4. Tsis txhob muaj av nyob rau ntawm daim lev.
5. Daim lev yuav tsum tau ziab kom qhuav. Daim lev uas tau nqus cov dej noo lawm yuav tawg thaum nthuav tawm thiab khaws dua. Feem ntau cov dej noo tsawg dua 0.2% yog qhov siv tau rau cov txheej txheem tsim khoom ib txwm.
6. Kev siv cov tshuaj resin impregnation tag nrho yog qhov tseem ceeb heev. Qhov solubility ntawm styrene tuaj yeem siv ua tus sawv cev rau kev sim qhov solubility ntawm daim lev hauv polyester resin, vim tias kev sim solubility ncaj qha hauv polyester tuaj yeem siv sijhawm ntau thiab nyuaj rau ntsuas. Kev siv styrene ua lwm txoj hauv kev tau txais thoob ntiaj teb thiab tau ua tus qauv.
7. Tom qab cov tshuaj pleev xim impregnation, cov xov paj yuav tsum tsis txhob xoob.
8. Lub lev yuav tsum yooj yim rau degas.
Cov qauv no pab ua kom ntseeg tau tias xaiv tau daim lev fiberglass zoo, uas tseem ceeb rau kev tsim cov nkoj nuv ntses fiberglass uas ruaj khov thiab ua haujlwm tau zoo.
