Foam daim kab xev feem ntau yog ua los ntawm cov ntaub ntawv ua npuas ncauj uas txuas nrog daim nplaum nplaum. Cov khoom ua npuas dej tuaj yeem ua los ntawm ntau yam khoom siv, suav nrog polyethylene (PE), polypropylene (PP), polyurethane (PU), lossis roj hmab. Cov ntaub nplaum rov qab tuaj yeem ua los ntawm cov ntaub ntawv xws li ntawv, ntaub, lossis yas zaj duab xis.
Nov yog cov ncauj lus kom ntxaws ntxiv ntawm cov khoom ntawm cov ntaub nplaum nplaum:
Ua Npuas Ncauj Khoom: Cov khoom ua npuas ncauj muab cov compressibility, cushioning, thiab sealing zog uas ua npuas ncauj ntaub ntawv zoo rau ntau yam kev siv. Nws feem ntau yog tsim los ntawm kev nthuav dav cov khoom siv polymer siv tus neeg sawv cev foaming. Cov txheej txheem foaming tsim cov npuas me me uas muab cov npuas dej nws tus yam ntxwv lub teeb thiab compressible zoo nkauj. Hom polymer siv thiab cov txheej txheem foaming tuaj yeem sib txawv raws li qhov xav tau ntawm cov ntaub nplaum ua npuas ncauj.
Backing Adhesive Tape: Cov nplaum nplaum nplaum yog cov substrate uas tuav cov khoom ua npuas ncauj rau saum npoo ntawm ib qho khoom. Nws muab qhov tsim nyog adhesion thiab tensile lub zog los xyuas kom meej tias cov ntaub nplaum nplaum tseem txuas rau saum npoo. Cov ntaub nplaum rov qab tuaj yeem ua los ntawm ntau yam ntaub ntawv, xws li ntawv, ntaub, lossis yas zaj duab xis, nyob ntawm daim ntawv thov thiab cov khoom xav tau.
Adhesive: Cov nplaum yog dab tsi khi cov khoom ua npuas ncauj rau daim kab xev rov qab thiab tseem mus rau qhov chaw ntawm cov khoom nws tau siv rau. Nws yuav tsum muaj qhov zoo adhesion thiab cohesion zog kom ntseeg tau tias daim kab xev tseem txuas rau saum npoo thiab tsis tev lossis delaminate thaum lub sijhawm. Hom nplaum siv tuaj yeem sib txawv nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom xav tau ntawm daim kab xev ua npuas ncauj.
Foam daim kab xev tuaj yeem pom nyob rau hauv ntau hom thiab thicknesses nyob ntawm daim ntawv thov. Nws tuaj yeem txiav rau ntau qhov sib txawv thiab cov duab nyob ntawm qhov xav tau siv, thiab nws tuaj yeem yuav hauv yob rau daim ntawv thov yooj yim. Thaum siv daim kab xev nplaum, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li cov chaw tsim khoom cov lus qhia kom tau txais txiaj ntsig zoo tshaj plaws, suav nrog cov ntawv thov kub, siab, thiab ntxuav ntawm qhov chaw ua ntej siv daim kab xev.
Nco ntsoov siv daim kab xev tsim nyog rau txhua daim ntawv thov kom ua tau zoo thiab ua haujlwm ntev.
