Hais txog cov ntaub ntawv ntim khoom, EPP yog ib qho tseem ceeb ntawm cov ntaub ntawv siv tau thiab tawv. Thaum nws los txog rau kev thauj khoom hnyav, nws puas tuaj yeem ua haujlwm tiag tiag? Nws yog ib qho tsim nyog hais tias Fumei Ntim, uas tau koom nrog hauv kev lag luam ntawm EPP ntim, tau tsim cov ntim khoom siv tau zoo rau ntau qhov kev lag luam nrog nws cov khoom siv tes ua haujlwm zoo thiab zoo heev. Lawv ua kom qhov zoo tshaj plaws ntawm EPP li cas?
Kev soj ntsuam ntawm EPP cov yam ntxwv ntawm cov khoom
EPP, nthuav polypropylene, yog them nrog nplua thiab zoo pores los ntawm cov qauv microscopic. Cov pores no yog "cov riam phom zais cia" uas txhim kho nws qhov kev ua tau zoo.
Ntawm ib sab, nws muab nws zoo heev cushioning kev ua tau zoo. Thaum cov khoom hnyav tau muab tso rau hauv nws thiab cov kev cuam tshuam sab nraud tuaj, cov pores tuaj yeem nrawm nrawm thiab deformed, zoo li micro springs, zoo dispersing thiab absorbing zog, zoo heev txo kev pheej hmoo ntawm kev puas tsuaj rau cov khoom hnyav.
Ntawm qhov tod tes, nws zoo toughness tso cai rau nws kom muaj kev ruaj ntseg nyob rau hauv lub siab thiab yuav tsis tawg yooj yim.
Thaum nws los txog rau compressive zog, EPP ua tau zoo dua. Nws tuaj yeem nqa cov khoom hnyav hnyav, thiab tseem nyob ruaj khov zoo li lub pob zeb txawm tias nyob rau hauv lub ntsej muag ntawm cov pob zeb thaum lub sijhawm thauj mus los thiab nyem thaum sib tsoo.
Ntxiv mus, qhov ceev ntawm EPP cov ntaub ntawv yog qhov tsawg. Thaum nws muaj peev xwm nqa tau zoo, nws yuav tsis ntxiv "ntau dhau" rau kev thauj mus los, ua rau nws lub teeb thiab siv tau.
