Cov Ntawv Thov
1. Precursor rau hindered amine lub teeb stabilizers (hales)
Dav siv raws li qhov tseem ceeb hauv nruab nrab hauv cov synthesis ntawm HOSS.
Nws yog cov stabilize zoo uas tiv thaiv cov polymers tiv thaiv kev ua haujlwm ntawm UV hluav taws xob thiab cua sov.
Cov cabilizers no yog qhov tseem ceeb nyob rau ncua lub neej ntawm plastics nthuav tawm hnub ci.
2. Polymer stabilization
Kev sib xyaw rau hauv cov plastics xws li polyolefins (PE, Polyesters, PolyTers, Polyings, PVC, thiab Txheej Txheem rau inhibit degradation.
Pab tiv thaiv disolioration, ploj ntawm cov tshuab muaj zog, thiab qhov chaw tawg.
3. Cov txheej txheem thiab xim av
Siv nyob rau hauv cov qauv ntawm UV-resistant txheej thiab xim pleev xim, txhim kho durability thiab tswj cov tsos nyob rau hauv lub hnub ci.
4. Cov ntawv nplaum thiab cov xov xwm
Ntxiv rau cov nplaum thiab cov xov xwm txhawm rau txhim kho huab cua tiv thaiv thiab txuas ntxiv lub neej ua haujlwm.
Cov txiaj ntsig
Kev ruaj khov UV: Ua cov tuav ua ntej tshaj plaws, txhawb rau lub teeb pom kev zoo thiab thermal ruaj khov ntawm cov polymers.
Tsis tshua muaj volatility thiab siab compatibility: sib xyaw zoo rau hauv polymer matrices tsis muaj volatilizing lossis blooming.
Inhibits dawb radical degradation: Hals muab tau los ntawm qhov sib xyaw ua kom zoo hloov scavenge dawb radicals tsim los ntawm UV kis tau.
Kev txhim kho cov khoom siv nyiaj: nce sab nraum zoov ruaj khov ntawm plastics thiab txheej.

2,2,6-tetramethyl-4-Piperidinol (CAS 2403-88-5) yog qhov tseem ceeb rau kev tiv thaiv cov polymers thiab cov tsho tiv no los ntawm UV-ua rau kev ua txhaum. Nws siv txhim kho lub durability, tsos, thiab cov kws kho mob cov khoom siv rau hnub ci, ua rau nws muaj kev lag luam, cov nplaum, thiab kev lag luam zoo nkauj.
