Iav sealant thiab structural adhesive muaj cov khoom sib txawv heev. Yog li ntawd, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm lawv thaum siv lawv. Kev siv tsis raug tuaj yeem ua rau muaj qhov tshwm sim loj. Nov yog ob qhov sib txawv tseem ceeb hauv lawv cov khoom:
Adhesive Strength: iav sealant, hauv kuv lub tswv yim, yog ib hom sealant, zoo ib yam li cov huab cua silicone feem ntau -resistant sealant. Yog li ntawd, nws lub zog nplaum tsis yog siab tshwj xeeb. Nws lub luag haujlwm tseem ceeb yog sealing. Nws yog qhov tseem ceeb ntawm silicone sealant. Structureal adhesive, ntawm qhov tod tes, yuav tsum muaj cov nplaum nplaum siab heev. Qhov no muaj xws li compressive zog, tensile zog, thiab shear zog. Cov nplaum nplaum yuav tsum muaj lub zog compressive ntau dua 65 MPa, lub zog tensile siab dua 30 MPa, thiab lub zog shear ntau dua 18 MPa.
Kev Pabcuam Lub Neej: Ntau cov khoom siv nplaum yog tsim los ua kom lub neej ntev ib yam li lub tsev. Ntawd yog, yog tias lub tsev tsim los rau 50-xyoo lifespan, ces cov txheej txheem nplaum siv yuav tsum muaj kev pab cuam lub neej ntawm 50 xyoo. Yog li ntawd, structural adhesives muaj lub neej ntev heev. Hauv qhov sib piv, silicone sealant feem ntau tsim teeb meem xws li tev thiab tawg tom qab ob peb xyoos. Yog li, cov txheej txheem adhesives yog qhov zoo tshaj rau silicone sealant.
