Ua ntej tshaj plaws, cia peb saib seb cov khoom siv ua npuas ncauj me me rau kev txhaws ntawm lub rooj zaum tub nkeeg yog dab tsi?

Yog li dab tsi yog epp khoom?Epp yog lub npe luv ntawm foamed polypropylene, thiab nws kuj yog ib yam ntawm cov khoom ua npuas ncauj, tab sis epp yog ib hom tshiab ua npuas ncauj yas.Sib txawv ntawm lwm hom ntaub ntawv ua npuas ncauj, epp muaj kev ua tau zoo dua thiab yog ib puag ncig zoo.Nws muaj cov khoom xws li rwb thaiv tsev kub, tuaj yeem rov ua dua tshiab, thiab tuaj yeem raug degraded, uas yog ib puag ncig zoo heev.Nws tuaj yeem siv rau hauv ntim khoom noj yam tsis muaj kev phom sij rau tib neeg lub cev.

Qhov thib ob, cia peb nkag siab tias cov khoom siv epp ua li cas?

Epp foaming hais yog cov khoom siv raw khoom thiab ntau tus neeg sawv cev pabcuam, hloov kho thiab cov neeg ua npuas dej tau muab tso rau hauv cov khoom ua npuas ua ke.Hauv cov khoom siv foaming, nyob rau hauv qhov kub thiab txias, kub siab thiab siab siab ze rau lub melting point ntawm polypropylene, tom qab tus neeg sawv cev foaming nkag mus rau hauv cov hais, nws yog instantly tso tawm ntawm ib txwm kub thiab siab rau daim ntawv.

Thaum kawg, cia peb saib cov yam ntxwv ntawm cov khoom siv epp.

1. Independent npuas, siab compressive zog, zoo toughness, muaj zog tshav kub tsis kam, zoo tshuaj kuj, tsawg VOC volatile organic tebchaw.

2. EPP muaj cov yam ntxwv ntawm kev ua haujlwm siab, ua haujlwm ntev, kev tiv thaiv ib puag ncig, compression thiab poob siab tsis kam, tsis muaj tshuaj lom thiab tsis muaj mob, tsis muaj ntxhiab tsw ntxhiab thiab ci xim, thiab lwm yam. Nws yog qhov tsim nyog rau menyuam yaus cov khoom ua si, rooj tog zaum, rooj zaum, hauv ncoo, cushions. thiab lwm yam ua npuas ncauj (ua npuas ncauj granules) muab tub lim.

Los ntawm cov ncauj lus kom ntxaws txog cov ntaub ntawv epp, peb yuav tsum muaj kev nkag siab tob txog cov ntaub ntawv epp.Nyob rau tib lub sijhawm, nws tseem pom zoo tias thaum yuav lub rooj zaum tub nkeeg, nws yog qhov zoo tshaj plaws los xaiv qhov ntim ntawm cov khoom epp, vim tias cov khoom ntim ntawm epp muaj kev nyab xeeb, tsis muaj tshuaj lom thiab tsis muaj formaldehyde, thiab yuav tsis ua rau ib qho kev puas tsuaj rau tus neeg siv kev noj qab haus huv.
