Water-based Adhesive yog dab tsi?
Water-based Adhesiveraws li ib tug dispersing nruab nrab yog ib pawg loj ntawm ib puag ncig tus phooj ywg adhesives. Cov kua nplaum raws li cov kua nplaum yog homogeneous systems nrog cov kuab tshuaj organic xws li benzene thiab toluene li dispersing media, thiab cov theem txuas ntxiv. Cov dej-raws li nplaum nplaum yog cov txheej txheem heterogeneous nrog dej raws li qhov nruab nrab dispersing.
Xaiv
Dej-raws li adhesive raws li qhov nruab nrab dispersing yog muab faib ua dej-soluble adhesives, dej-dispersed adhesives thiab dej-emulsion adhesives.
Cov nplaum nplaum dej feem ntau yog muab faib ua dej-raws li polyurethane adhesives, dej-raws li polyacrylate adhesives, dej-raws li epoxy adhesives, dej-raws li silicone nplaum, polyvinyl acetate emulsion adhesives, neoprene latex thiab hais txog.
Dej-raws li adhesives mas muaj xws li phenolic aldehyde, urea aldehyde, melamine formaldehyde, polyvinyl acetate emulsion, EVA emulsion, polyacrylate emulsion, waterborne polyurethane, thiab dej-emulsion epoxy nplaum, thawj theem nyob rau hauv Tuam Tshoj.
Qhov zoo
Dej-raws li adhesives yog ib qho ntawm txoj kev loj hlob ntawm cov nplaum nplaum. Piv nrog cov kuab tshuaj raws li cov nplaum nplaum, lawv muaj qhov zoo ntawm cov kuab tshuaj tsis pub dawb, ua tau raws li qhov yuav tsum tau ua ntawm ib puag ncig, tus nqi qis, tsis muaj hluav taws kub thiab nyab xeeb siv. Cov ntsiab lus tseem ceeb yog qhov siab, txog li 50 feem pua ~ 60 feem pua. Txawm li cas los xij, vim qhov qeeb ntawm cov dej tsis zoo, cov kua nplaum kho qeeb los yog xav tau kom sov thiab qhuav.
