Thaum xyoo 1980s, European thiab Asmeskas cov kws tshaj lij pom tau tias nyob rau hauv cov dej kub uas siv cov kav dej yas, cov hlau hauv cov khoom siv tau yooj yim corroded, ua rau cov khoom puas tsuaj sai. Xyoo 1982, cov kws tshaj lij tau txiav txim siab tias thaum cov yeeb nkab tau rhuab, nws yooj yim dua rau cov pa oxygen molecules nkag mus rau hauv cov yas txheej thiab nkag mus tob rau hauv cov dej hauv cov yeeb nkab, ua rau corrosion sai ntawm cov hlau hauv cov khoom siv. Yog li ntawd, cov pa oxygen barrier raj tau tsim.
Hauv Tebchaws Europe thiab Tebchaws Meskas, kev siv cov pa oxygen barrier kav hauv cov cua sov mus txog 70 feem pua. Tom qab ze li ntawm 20 xyoo ntawm kev ua tau zoo, lub neej ntawm cov khoom siv hlau hauv cov pa oxygen barrier cov kav dej tuaj yeem txuas ntxiv los ntawm 10-20 xyoo.
