Kev txiav txim siab tseem ceeb rau xaiv Edgebanding Kub-Cov nplaum nplaum
Edgebanding kub-melt adhesive, ib qho tshwj xeeb nplaum uas tsim los rau kev sib khi cov npoo ntawm cov vaj huam sib luag ntoo, yog tus cwj pwm los ntawm nws cov kuab tshuaj -dawb muaj pes tsawg leeg thiab cov khoom siv thermoplastic. Thaum raug rhuab mus rau qhov kub thiab txias, nws hloov los ntawm lub xeev khov rau hauv lub xeev molten; nws yog ces siv rau engineered ntoo substrate los yog edgebanding khoom. Raws li nws txias, nws rov qab mus rau lub xeev ruaj khov, yog li tsim kom muaj kev ruaj khov ntawm cov khoom siv edgebanding thiab cov substrate. Thaum xaiv ib qho, yam tseem ceeb uas yuav tsum xav txog suav nrog nws cov kuab tshuaj-dawb xwm, cov yam ntxwv ntawm cov thermoplastic, ib puag ncig tus phooj ywg, thiab kev sib raug zoo nrog cov khoom siv substrate.
Cov khoom siv hauv paus rau Edgebanding Kub- Melt Adhesives
Raws li lawv cov ntaub ntawv tseem ceeb, edgebanding kub-cov nplaum nplaum tuaj yeem faib dav rau hauv peb hom hauv qab no: 1) EVA (Ethylene-Vinyl Acetate Copolymer Resin)-raws li kub- cov nplaum nplaum nplaum: Cov no tuaj yeem muab faib ua ob hom: {5} ntau dua muab tub lim-dawb. 2) Polyamide-raws li kub-melt adhesives: Cov nplaum no nthuav tawm cov cua sov ua haujlwm zoo thiab kho sai sai, txawm hais tias lawv zoo li yuav kim dua. 3) HMPU (Polyurethane)-raws li kub- qhov kev ua tau zoo tshaj plaws ntawm kev ua tau zoo kub-cov nplaum nplaum, cov no feem ntau siv rau edgebanding siab-zoo engineered wood panels. EVA, polyamide, thiab polyurethane sawv cev rau feem ntau cov ntaub ntawv hauv paus, txhua tus muaj cov yam ntxwv sib txawv thiab cov chaw tshwj xeeb ntawm daim ntawv thov.
Cov yam ntxwv cuam tshuam rau viscosity
Thaum xaiv ib qho edgebanding kub-kua nplaum nplaum, ntau yam tseem ceeb yuav tsum tau muab rau hauv tus account. Viscosity, nyob rau hauv thiab ntawm nws tus kheej, tsis tuaj yeem ua ib qho kev ntsuas rau kev txiav txim siab tag nrho kev ua tau zoo ntawm qhov kub - nplaum nplaum. Feem ntau hais lus, adhesives nrog viscosity siab dua yuav muab qhov zoo tshaj qhov pib tack zog; Txawm li cas los xij, lawv cov khoom siv hauv daim ntawv thov-tshwj xeeb yog lawv qhov kev nthuav dav- tej zaum yuav muaj kev cuam tshuam me ntsis. Viscosity ncaj qha cuam tshuam rau thawj lub zog tack, thiab siab dua -viscosity adhesives feem ntau zoo dua rau siv nrog qis dua -particleboard substrates.
Cov txheej txheem xaiv rau cov khoom sib txawv Edgebanding
Thaum edgebanding qis dua - zoo particleboard, nws yog feem ntau pom zoo kom xaiv ib tug kub - yaj nplaum nrog viscosity siab dua. Qhov kev pom zoo no tshwm sim los ntawm qhov tseeb tias siab - viscosity adhesives muaj qis fluidity; Thaum lub sijhawm ua ntawv thov, lawv tsis tshua muaj siab heev-piv rau qis-viscosity adhesives- kom pom ntau dhau mus rau hauv cov qauv ntxeem tau ntawm particleboard lub ntug, yog li ua kom muaj qhov sib xws thiab zoo ib yam txheej ntawm cov nplaum raws ntug ntawm lub vaj huam sib luag. High-viscosity kub-cov nplaum nplaum yog tsim rau qis dua- cov ntaub ntawv zoo, kom ntseeg tau tias daim ntawv thov tsis sib xws ntawm cov nplaum raws cov npoo.
