kho / phenolic lim ntawv

Phenolic resin lim caij

Qhov kub thiab txias muaj qhov cuam tshuam zoo rau cov viscosity ntawm cov kua organic, qhov kub thiab txias, qhov qis dua qhov viscosity, zoo dua cov kua fluidity, nyob rau hauv kev lag luam tsim cov organic kua cov ntaub ntawv feem ntau nyob rau hauv 60-120 ° C kom muaj fluidity zoo dua, uas yog. kuj yog lim ntawm cov khoom kom tshem tawm impurities ntawm qhov kub thiab txias ua haujlwm.

Nws yog ua los ntawm phenolic resin raws li lub cev pob txha, ua ke nrog polyester fiber sintered ntawm qhov kub thiab txias. Piv nrog cov lim dej zoo tib yam organic fiber ntau, phenolic resin lim muaj qhov ruaj khov zoo, ua haujlwm kub thiab ua haujlwm shrinkage, thiab muaj peev xwm tswj tau cov kab mob siab. Nyob rau tib lub sijhawm, cov kua nplaum xws li cov coatings yog ib qho yooj yim los tsim kev txaj muag tsis pom kev nyob rau saum npoo ntawm cov khoom siv lim thaum pom, thiab cov qauv tsim ntawm qhov chaw ntawm cov phenolic resin lim caij tuaj yeem ua rau thaj chaw pom thiab muaj peev xwm ua kom tsis muaj paug. ntawm cov khoom lim, uas muaj kev tshwj xeeb ntawm kev tshem tawm impurities thiab deformable hais nyob rau hauv ntau yam colloids.

Cov txheej txheem loj ntawm cov pore loj ntawm cov khoom lim tuaj yeem paub txog ntau theem pom, uas yog tshwj xeeb tshaj yog haum rau kev pom ntawm cov viscosity siab thiab siab turbidity kua. Nyob rau tib lub sijhawm, phenolic resin lim caij muaj lub neej ua haujlwm ntev, uas tuaj yeem txo kev noj thiab txo cov tswv yim ntawm cov tuam txhab cov nqi.

Phenolic resin lim core yog ua los ntawm phenolic resin li pob txha, ua ke nrog polyester fiber sintered ntawm qhov kub thiab txias. Piv nrog rau cov organic fiber ntau lim core, phenolic resin lim core muaj kev ruaj ntseg zoo, kev ua haujlwm kub thiab kev ua haujlwm shrinkage, thiab muaj peev xwm tswj tau cov kab mob siab. Nyob rau tib lub sijhawm, cov kua nplaum xws li cov coatings yog ib qho yooj yim los tsim kev txaj muag tsis pom kev nyob rau saum npoo ntawm cov khoom siv lim thaum pom, thiab cov qauv tsim ntawm qhov chaw ntawm cov phenolic resin lim caij tuaj yeem ua rau thaj chaw pom thiab muaj peev xwm ua kom tsis muaj paug. ntawm cov khoom lim, uas muaj kev tshwj xeeb ntawm kev tshem tawm impurities thiab deformable hais nyob rau hauv ntau yam colloids. Cov txheej txheem loj ntawm cov pore loj ntawm cov khoom lim tuaj yeem paub txog ntau theem pom, uas yog tshwj xeeb tshaj yog haum rau kev pom ntawm cov viscosity siab thiab siab turbidity kua. Nyob rau tib lub sijhawm, phenolic resin lim caij muaj lub neej ua haujlwm ntev, uas tuaj yeem txo kev noj thiab txo cov tswv yim ntawm cov tuam txhab cov nqi.
