Raws li peb txhua tus paub, cov ntaub ntawv xws li daim txhuam cev, foamed yas, roj hmab thiab ntoo feem ntau xaiv los ua cov ntaub ntawv cushioning thiab tiv thaiv kev sib tsoo hauv lub neej tiag tiag. Raws li ib qho ntawm cov khoom siv hlau ntxeem tau, dab tsi yog qhov zoo ntawm nws lub zog nqus thiab buffering?

Nyob rau hauv layman cov ntsiab lus, txhua lub zog-absorbing thiab buffering khoom muaj nws tus kheej siab tshaj plaws load-bearing ncov tus nqi. Tom qab lub cheeb tsam cheeb tsam tshaj ib tug tej lub siab, lub zog-absorbing thiab buffering nyhuv yuav ploj. Yog li ntawd, cov sponges, foamed plastics, roj hmab, foamed aluminium, thiab lwm yam. Lub siab ntau yog tam sim no qhov zoo tshaj plaws thiab dav siv zog-absorbing tsis khoom.

Raws li cov khoom siv hlau ultra-lub teeb uas tuaj yeem ntab rau hauv dej, txhuas ua npuas dej muaj qhov ntom ntom ntawm 0.2-0.4g / cm³, uas yog li 1/30 ntawm qhov ntom ntawm cov hlau; Txawm li cas los xij, nws txoj hlua khi yog 1.5 npaug ntawm cov hlau; nyob rau hauv tib qhov hnyav, Lub zog compressive yog 5 npaug ntawm cov hlau; Nyob rau tib lub sijhawm, kev ua haujlwm damping ntawm foamed aluminium yog 5-10 npaug ntawm cov hlau, thiab foamed aluminium nrog lub porosity ntau dua 80% tuaj yeem nqus 20J / cm³ ntawm lub zog thaum deformed los ntawm 50%, uas yog qhov zoo tshaj plaws. . Shock-absorbing khoom.
