Cov ntsiab cai thiab kev ua tau zoo ntawm cov khoom thauj cushioning

Thaum thauj cov ntaub ntawv cushioning raug rau sab nraud quab yuam, lawv nqus lub zog los ntawm kev deformation, tiv thaiv cov khoom puas. Cov txheej txheem no zoo sib xws rau cov khoom siv viscoelasticity; viscoelastic cov ntaub ntawv, thaum raug kev ntxhov siab, tuaj yeem khaws lub zog thiab tawg qee qhov ntawm nws thaum tshav kub los ntawm kev sib txhuam sab hauv.

Rau cov ntaub ntawv foamed cushioning, cov txheej txheem molding cuam tshuam rau kev ua haujlwm kawg. Cog fiber ntau cushioning cov ntaub ntawv cia siab rau cov dej bridging rog thiab cohesive rog generated los ntawm fiber dabtsi yog khoov mus cuag fibers thiab tsim ib tug peb - qhov sib txawv network qauv. Bubble nucleation yog theem tseem ceeb ntawm kev txiav txim siab cov qauv ntawm cov khoom siv foamed.

Kev ua haujlwm zoo (kev kho dua tshiab) yog qhov yuav tsum tau ua, kom ntseeg tau tias cov khoom ntim tau raug tiv thaiv los ntawm kev ntxhov siab ntau zaus. Cov khoom siv yuav tsum tsis txhob hnov ​​​​qab txog kev nyab xeeb xws li cov av noo thiab qhov kub thiab txias kom tswj tau qhov kev ua haujlwm ruaj khov, thiab yuav tsum tsis txhob nqus dej los yog muaj cov khoom corrosive kom tsis txhob muaj kev cuam tshuam ntawm cov khoom ntim. Kev siv cov khoom ntim cushioning yuav tsum ua qhov tseem ceeb ntawm kev ua tau zoo, kev yooj yim, kev sib raug zoo ib puag ncig, thiab tus nqi- ua tau zoo.
