Pem teb substrate yog ib feem ntawm kev sib xyaw flooring.Lub hauv paus muaj pes tsawg leeg ntawm substrate yog yuav luag tib yam, nws tsuas yog nyob ntawm qhov zoo, tsis hais hom ntawm substrate;hauv pem teb substrate tso nyiaj rau ntau tshaj 90% ntawm tag nrho cov hauv pem teb muaj pes tsawg leeg (nyob rau hauv cov nqe lus ntawm solids), lub substrate account rau txog 70% ntawm tus nqi qauv ntawm tag nrho cov laminate flooring.Tus nqi ntawm cov khoom siv ntoo thiab cov khoom siv yog qhov tseem ceeb ntawm cov khoom siv hauv paus.Tsis tas li ntawd, vim qhov sib txawv ntawm cov khoom sib xyaw ntawm cov khoom siv hauv paus thiab qhov sib txawv ntawm kev siv cov nplaum, qhov sib txawv ntawm tus nqi ntawm cov khoom siv ua haujlwm txawv.
Cov khoom siv qib siab E1 yog cov khoom siv zoo tshaj plaws, thiab cov nqi ntawm cov khoom tiav ntawm cov khoom sib txawv ntawm cov khoom sib txawv heev.Raws li cov qauv hauv tebchaws tam sim no, ntawm 17 lub ntsiab lus qhia txog kev ua tau zoo uas tuaj yeem kuaj tau rau laminate flooring, 15 muaj feem xyuam rau cov khoom siv hauv paus.lub neej muaj txiaj ntsig.Tej yam xws li qhov cuam tshuam tsis kam ntawm cov khoom, qhov dej tsis kam ntawm cov khoom, thiab qhov seem stability ntawm cov khoom yog tag nrho cov ze ze rau qhov zoo ntawm lub substrate.Raws li cov txiaj ntsig ntawm kev soj ntsuam kuaj hauv tebchaws, ntau dua 70% ntawm cov laj thawj rau qhov tsis tsim nyog laminate flooring yog tshwm sim los ntawm qhov zoo ntawm cov khoom siv hauv paus.Txhawm rau txo cov nqi, qee cov tuam txhab siv cov khoom siv tsis zoo thiab cov txheej txheem rov qab los ua cov txheej txheem dub-core substrates.Qhov txawv feature ntawm dub-core substrates yog hais tias lawv siv ib co raw cov ntaub ntawv uas tsis haum rau hauv pem teb substrates, xws li inconsistent ntoo hom, thiab siv bark, sawdust, thiab lwm yam raws li cov khoom siv raw ntawm cov khoom siv hauv paus, xws li cov khoom siv hauv paus. fiber ntau tsis tuaj yeem ua tiav lub cev thiab cov khoom siv kho tshuab kom zoo thaum lub sijhawm nias, thiab kev ua tiav tsis tuaj yeem tsim nyog txhua.Tus nqi ntawm cov substrates ua los ntawm cov khoom siv raw yog qis dua li cov khoom siv uas raug xaiv.Dub-hearted substrates tsis tsuas yog ua tsis tau raws li lub cev thiab lub zog, tab sis kuj tsis muaj txoj hauv kev los xav txog kev noj qab haus huv.
Ib qho yog qhov ntom ntom zoo.Qhov ntom ntawm cov substrate cuam tshuam rau lub cev thiab lub zog ntawm cov khoom thiab cuam tshuam ncaj qha rau hauv pem teb.Lub teb chaws tus qauv xav kom qhov ceev ntawm hauv pem teb yog ≥ 0.80g / cm3.Cov lus qhia txog kev txheeb xyuas: Xav txog qhov hnyav hauv pem teb nrog koj txhais tes.Los ntawm kev sib piv qhov hnyav thiab qhov hnyav ntawm ob lub plag tsev, cov plag tsev zoo feem ntau muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom;zoo hauv pem teb substrates muaj cov khoom sib xws tsis muaj variegation, thiab xav tias nyuaj rau qhov kov, thaum cov hauv pem teb tsis zoo muaj cov khoom ntxhib, xim sib txawv, thiab cov plaub hau.
Qhov thib ob yog cov dej nqus thickness expansion npaum li cas.Cov dej nqus thickness nthuav dav tus nqi qhia txog kev ua haujlwm ntawm cov khoom pov thawj noo noo, qhov ntsuas qis dua, qhov ua tau zoo ntawm cov dej noo-pov thawj.Nyob rau hauv lub teb chaws tus qauv tam sim no rau laminate flooring, cov dej nqus thickness expansion yuav tsum yog ≤2.5% (cov khoom zoo tshaj).Cov lus qhia txog kev txheeb xyuas: siv ib qho me me ntawm cov qauv hauv pem teb kom ntub dej hauv chav dej rau 24 teev, kom pom qhov loj ntawm cov thickness expansion, qhov zoo ntawm qhov me me nthuav dav zoo dua.
High-quality substrate yuav tsum muaj cov yam ntxwv hauv qab no:
Ua ntej, ntoo yuav tsum tau tshiab txaus tsis muaj rot thiab ntau bark." Txwv tsis pub, cov ntoo ntawm cov ntoo fibers yuav raug txo qis, lub zog ntawm hauv pem teb yuav tsis txaus, thiab kev pabcuam lub neej yuav luv dua."
Qhov thib ob, nws yog ib qho tsim nyog los xyuas kom meej tias qhov ntom ntawm cov khoom siv ntoo sib txawv yog nyob ze, nyiam dua ib hom ntoo.Txhawm rau kom tswj tau zoo dua qhov purity thiab freshness ntawm hom ntoo, nws yog qhov zoo tshaj plaws rau cov tuam txhab tsim khoom tsim nyob rau hauv qhov chaw uas cov ntoo loj tuaj, thiab xaiv hom ntoo ruaj khov, thiaj li ua kom lub cev tsis sib xws thiab kev siv tshuab. kev ua tau zoo ntawm cov ntoo fibers siv los tsim cov plag tsev ntoo.Nrog rau cov xwm txheej zoo li no, cov ntoo hauv pem teb tuaj yeem muaj qhov ruaj khov zoo dua.
