Daim Ntawv Thov:
UV-P muab kev tiv thaiv ultraviolet nyob rau hauv ntau ntau ntawm cov polymers suav nrog hom styrene homo- thiab
copolymers, engineering plastics xws li polyesters thiab acrylic resins, polyvinyl chloride, thiab
Lwm Halogen muaj polymers thiab copolymers (piv txwv li vinylidenes), acetals thiab cellulose
Esters. Elastomers, cov nplaum, Polycarboonates, polyurethanes, thiab qee qhov cellulose estrers thiab
EPOXY cov ntaub ntawv kuj tau txais txiaj ntsig los ntawm kev siv UV-P
Nta / Cov Nyiaj Pab
UV-P yam ntxwv ib qho kev nqus tau zoo ntawm ultraviolet hluav taws xob hauv {1}} nm cheeb tsam. Nws kuj tseem muaj qib siab ntawm photostility ntev ntev ntawm lub teeb pom kev ntev. Lub siab nqus tau nrog photostabilations nrog photosability thiab muaj peev xwm tso tawm lub zog hauv txoj kev tsis zoo ua rau kev cuam tshuam rau kev cuam tshuam tiv thaiv kev cuam tshuam ntawm cov teeb ci ntawm ultraviolet teeb. UV-P muaj cov zaub mov rau kev tiv tauj pom zoo hauv cov khoom siv tsis yooj yim thiab siv cov khoom lag luam, khaws cia cov khoom lag luam hauv cov teeb meem ntawm lub teeb.
Cia:
Zam kev tshav ntuj, muaj lub teeb ci, noo noo, thiab lub teeb ci ruaj ruaj muaj cov sulphur lossis halogen hais. Nws yuav tsum tau muab cia rau hauv kev kaw, qhuav thiab deb ntawm lub teeb.
