Daim ntawv thov ntawm epoxy resin yeeb nkab nyob rau hauv fais fab nroj tsuag
Lwm thaj chaw siv rau iav fiber reinforced epoxy kav nyob rau hauv lub hwj chim sector yog nyob rau hauv lub fais fab nroj tsuag. Vim nws cov ntaub ntawv hloov tau yooj yim, cov yeeb nkab muaj qhov hnav tsis zoo, yog li nws tsim nyog rau cov yeeb nkab flue, thiab nws txoj kev pab cuam lub neej yog ob zaug ntev npaum li cov yeeb nkab steel. Thaum cov ntsiab lus ntawm cov hmoov tshauv yog 10%, yog tias cov yeeb nkab tig plaub zaug (txhua lub sijhawm tig lub kaum sab xis yog 90 °), qhov kev pab cuam lub neej ntawm cov yeeb nkab steel yog ob xyoos, thiab cov iav fiber reinforced epoxy resin yeeb nkab yog plaub xyoos.
Ntxiv rau qhov siv los ua cov yeeb nkab flue, cov yeeb nkab no tuaj yeem siv rau qhov twg qhov siab tsis tshaj 10 bar thiab qhov kub tsis tshaj 65 ° C. Hauv Tebchaws Meskas, kwv yees li 450 mais ntawm cov iav fiber ntau cov kav dej yas tau raug teeb tsa kom deb li deb ntawm cov nroj tsuag thermal. Xyoo 1975, nws tau npaj yuav txuas ntxiv mus rau 140 mais.
Ntxiv rau qhov kev pab cuam lub neej ntev, lwm qhov tseem ceeb ntawm cov iav fiber reinforced epoxy yeeb nkab yog nws lub teeb yuag thiab yooj yim installation. Cov iav fiber reinforced epoxy resin yeeb nkab tsis tuaj yeem welded thiab yuav tsum tau txuas nrog bolts, los yog ntsia nrog flanges, thiab cov kav dej kuj tuaj yeem txuas nrog gluing.
Epoxy yog cov khoom siv qib siab uas siv ntau txoj hauv kev, los ntawm kev tsim kho mus rau qhov chaw dav hlau. Epoxy nplaum nplaum nplaum zoo rau kho epoxy pwm. Yog li ntawd, gluing yog ib qho ntawm feem txhim khu kev qha thiab pheej yig txoj kev rau kev koom nrog iav fiber reinforced epoxy kav. Qhov tsis zoo ntawm gluing yog tias txoj kev sim tsis zoo tag nrho. Cov iav fiber ntau reinforced epoxy yeeb nkab tam sim no tuaj yeem raug sim siab. Lwm txoj kev kuaj tsis muaj kev puas tsuaj (sib npaug rau kev kuaj X-ray ntawm cov kav hlau) tsis siv tam sim no.
