Cov qauv tshuaj thiab cov khoom ntawm polyamine epoxy hmoov txheej

Cov qauv tshuaj thiab cov khoom ntawm polyamine epoxy hmoov txheej
Hue
(Zoo heev) alicyclic → aliphatic → amide → aromatic amine (tsis zoo)
Kev loj hlob
(qis) alicyclic → aliphatic → aromatic → amide (siab)
Lub neej lauj
(Long) aromatic → amide → alicyclic → aliphatic (luv luv)
Kho
(Fast) aliphatic → alicyclic → amide → aromatic (slow)
Kev khaus
(Nruab) aliphatic → aromatic → alicyclic → amide (tsis muaj zog)
Gloss
(Zoo heev) aromatic → alicyclic =Aliphatic → polyamide → aliphatic amine (tsis zoo)
Kev mos
(mos) polyamide → aliphatic → alicyclic → aromatic (nyuaj)
Adhesion
(zoo heev) polyamide → alicyclic → aliphatic → aromatic (zoo)
Acid kuj
(zoo heev) aromatic → alicyclic → aliphatic → polyamide (hauv qab)
Dej tsis kam
(zoo heev) polyamide → aliphatic amine → alicyclic amine → aromatic amine (zoo)
Cov qauv tshuaj thiab cov khoom ntawm bisphenol A resin kho cov khoom
Rau gloss, aromatics yog qhov zoo tshaj plaws thiab aliphatics yog qhov phem tshaj. Cov cuab yeej no cuam tshuam los ntawm kev kho qhov kub thiab txias, thiab cov gloss yuav zoo dua thaum kub nce. Raws li kev softness, polyamides nrog kev ncua deb ntawm cov pab pawg ua haujlwm zoo dua, thaum cov tshuaj tsw qab amines uas muaj qhov sib txawv ntawm qhov sib txawv loj dua. Thaum tshav kub kub tsis kam yog qhov txawv ntawm softness, thaum adhesion yog zoo ib yam nrog softness. Tshuaj tiv thaiv (acid resistance) cuam tshuam los ntawm cov qauv tshuaj, aromatics kuj zoo, thiab aliphatic amines thiab polyamides yog yooj yim corroded los ntawm cov tshuaj. Kev tiv thaiv dej yog tswj hwm los ntawm qhov loj ntawm cov pab pawg ua haujlwm. Polyamides uas tsis tshua muaj siab concentration ntawm cov pab pawg ua haujlwm thiab siab hydrophobicity yog cov dej-resistant ntau dua, thaum aromatics nrog siab concentration ntawm cov pab pawg ua haujlwm tsis tshua muaj resistant.
