Thaum lub sijhawm tsim thiab tsim cov PE boards, kev xaiv cov khoom siv raw thiab cov txheej txheem tsim kho yuav tsum tau them sai sai rau. Cov khoom siv raw rau kev tsim cov ntawv PE yog cov khoom siv raw inert molecular, thiab cov kua dej ntawm cov khoom siv raw tsis zoo. Qhov no tau coj teeb meem me ntsis rau kev tsim cov ntawv PE, yog li kev xaiv cov khoom siv raw rau kev tsim cov ntawv PE yog qhov tseem ceeb heev. Txhawm rau daws cov teeb meem ntawm qhov nyuaj ntawm kev tuag thiab cov pa roj nce ntxiv los ntawm cov kua dej tsis zoo ntawm cov khoom siv raw, qee cov roj nplua nyeem yuav tsum tau ntxiv thaum xaiv cov khoom siv raw. Kev xaiv cov roj nplua nyeem feem ntau suav nrog stearic acid thiab ntsev. Cov ntawv PE tsim tawm hauv txoj kev no muaj cov khoom siv sib xws thiab tsis muaj cua npuas.
Hais txog cov txheej txheem tsim kho, cov vaj huam sib luag PE zoo dua tuaj yeem tau txais los ntawm kev txhim kho cov txheej txheem tsim kho. Cov txheej txheem tseem ceeb los txhim kho cov txheej txheem yog kom nkag siab txog qhov ntau ntawm cov khoom pub, ntsuas qhov ntau ntawm cov khoom xav tau ua ntej, tsis txhob sau ntau dhau lossis tsis txaus cov khoom, thiab kho qhov ntau ntawm cov khoom rau qib siab dua rau PE boards. Nws yog qhov zoo tshaj plaws los siv txoj kev txhaj tshuaj siab thiab ceev ceev los tsim, kom tau txais cov phaj zoo dua.
