Puas yog nws tsim kev puas tsuaj rau kev siv cov tais ntawv pov tseg rau lub sijhawm ntev?

1. Tsis yog txhua lub tais uas siv tau pov tseg tsis muaj teeb meem. Tsuas yog cov ntawv tais uas ua tau raws li lub teb chaws tus qauv yuav tsis muaj teeb meem rau tib neeg lub cev, tab sis tsis pom zoo siv mus ntev. Txhawm rau kom ua tiav cov txiaj ntsig dej-pov thawj, cov ntaub ntawv pov tseg yuav raug coated nrog polyethylene barrier rau ntawm phab ntsa sab hauv. Dej zaj duab xis poly. Txawm li cas los xij, yog tias cov khoom xaiv tsis zoo los yog cov txheej txheem kev ua haujlwm tsis zoo txaus, polyethylene yuav raug oxidized rau carbonyl compounds thaum lub sij hawm kub melting los yog smearing rau ntawm daim ntawv khob, uas yuav ua rau muaj kev puas tsuaj rau tib neeg noj qab haus huv.

2. Cov phab ntsa sab hauv ntawm cov khoom siv uas siv cov tais ntim khoom pov tseg ntawm kev ua lag luam yog ua los ntawm cov ntawv coated, uas yog cov yas yas hauv polyethylene. Tam sim no ntau lub khob ntawv siv cov ntawv coated tsis yog paraffin. Tab sis tsis muaj paraffin wax, sab nraud ntawm lub khob "tiv thaiv" tuaj yeem ua pwm thaum nws ntub.

3. Cov khoom uas tsis tsim nyog kev ua tau zoo ntawm cov ntawv pov tseg cov tais feem ntau suav nrog kev ua haujlwm ntawm cov dej xau thiab lub zog compressive. Kev ua haujlwm tsis tsim nyog thiab lub zog compressive yuav cuam tshuam ncaj qha rau kev siv cov neeg siv khoom; Qhov teeb meem ntawm qhov ntsuas qhov ntsuas tsis tsim nyog yog tias qhov kev ncua deb ntawm lub tshuab luam ntawv thiab lub khob lub qhov ncauj thiab hauv qab ntawm lub khob tsis tau raws li tus qauv yuav tsum tau ua, uas yuav ua rau cov neeg siv khoom tuaj yeem hu ncaj qha rau cov txheej txheem luam ntawv thaum siv. qhov chaw, noj cov tshuaj uas tsim kev puas tsuaj rau tib neeg lub cev.
