Dab tsi tshwm sim tshwm sim hauv kev ua haujlwm ntxiv ntawm fiberglass raw yarn muaj feem cuam tshuam nrog kev ua haujlwm ntawm tus neeg sawv cev ntub dej?
(1) Kev tsiv teb tsaws ntawm tus neeg sawv cev sizing. Thaum lub sij hawm ziab ntawm cov ntaub qhwv nyoos, ib feem ntawm tus neeg sawv cev sizing yog nqa los ntawm dej thiab tsiv mus rau txheej txheej. Cov roj cov ntsiab lus ntawm covfiberglasssab hauv thiab sab nraud ntawm cov ntaub lo lo ntxhuav nyoos tsis sib haum, thiab cov ntaub lo lo ntxhuav tsis yooj yim rau decompose, uas cuam tshuam rau cov khoom zoo. Kev txhim kho ntawm qhov tshwm sim ntawm kev tsiv teb tsaws yuav tsum muaj cov emulsion kom muaj qee qhov me me kom cov dej tsis tuaj yeem nqa nws. Tshwj xeeb, thaum npaj cov zaj duab xis-tsim tus neeg sawv cev emulsion, nws yog ib qho tsim nyog los tswj cov qib ntawm kev khi ntawm cov emulsifier thiab cov dej molecules ntawm qhov chaw ntawm cov emulsion hais thiab cov nyiaj ntawm hydrogen bonds tsim ntawm ob. Yog tias qhov kev sib khi tsis zoo, cov khoom muaj cov dej tsis zoo thiab cov emulsion tsis ruaj khov; Yog tias kev khi ruaj khov heev, cov dej molecules yuav nqa cov khoom emulsion tawm los ntawm hydrogen bonding thaum lub sij hawm evaporation thiab migration txheej txheem.
(2) Fuzzing. Thaum lub sij hawm debonding txheej txheem, lubfiberglassfilaments tawg thiab tsim fuzz. Cov laj thawj rau fuzzing yog: ntawm ib sab, lubricity ntawm impregnating tus neeg saib xyuas zaj duab xis tsis txaus thiab qhov sib txhuam coefficient loj heev; Ntawm qhov tod tes, thawj filaments tsis zoo bundled. Qhov no muaj feem xyuam rau LOI tus nqi ntawm tus neeg sawv cev impregnating, hom zaj duab xis-tsim tus neeg saib xyuas, qhov hnyav molecular ntawm cov yeeb yaj kiab-forming tus neeg saib xyuas thiab qhov nro ntawm tus neeg ua yeeb yaj kiab. Yog tias qhov hnyav molecular loj dhau lossis me dhau, lossis qhov nro ntawm qhov loj dhau, fuzzing yog qhov yooj yim tshwm sim. Qhov no kuj muaj feem xyuam rau hom thiab tus nqi ntawm lub lubricating tivthaiv nyob rau hauv tus neeg sawv cev impregnating.
(3) Kev ua haujlwm ntawm cov ncuav mog qab zib nyoos. Lub deformation ntawm raw cov ncuav mog qab zib thiab cov phenomenon sticking ntawm cov khaubncaws sab nraud povtseg thaum lub sij hawm ziab yuav muaj kev cuam tshuam tsis zoo rau kev ua haujlwm tom ntej.fiberglass. Yog hais tias lub ncuav mog qab zib nyoos yog mos thiab deformed, cov xov paj yog yooj yim rau unwind thaum lub sij hawm unwinding; Yog hais tias lub ncuav mog qab zib nyoos yog ib qho nyuaj heev los yog cov interlayers yog cov nplaum nplaum, cov iav fiber ntau yog yooj yim rau kev puas tsuaj thiab cov plaub hau hnyav heev thaum lub sij hawm unwinding. Yog li ntawd, nws yog ib qho tsim nyog yuav tau kho tus nqi ntawm txhua feem ntawm tus neeg sawv cev sizing kom ua cov ncuav mog qab zib nyoos ntawm cov mos mos thiab tawv.
