Cov plastics xav tau UV tsis kam rau txo cov kev cuam tshuam ntawm ultraviolet (UV) hluav taws xob los ntawm lub hnub ci, uas tuaj yeem hais txog kev ncaj ncees thiab cov tsos mob. Ntawm no yog cov qauv piav qhia:
1. UV hluav taws xob cuam tshuam:
- Tshuaj lom neeg Decadation: UV RAWS RAWS XYUAS cov saw hlau polymer hauv plastics los ntawm photOregradation, ua rau tsis muaj zog ntawm cov roj av. Qhov no ua rau brittleness, kev tawg, thiab txo lub zog tensile.
- Kev ua kom zoo nkauj: UV kis ua rau kev faus, tshem tawm, thiab chalking, ploj zuj zus ntawm kev pom ntawm cov khoom siv yas.
2. Daim ntawv thov yuav tsum tau UV tiv taus:
- Siv sab nraum zoov: cov khoom zoo li cov rooj tog vaj, cov khoom siv tsheb, thiab ntim khoom, thiab ntim khoom, yuav tsum muaj lub hnub nyoog ntev.
- Kev Nyab Xeeb thiab Kev Ruaj Ntseg: Kev tsis txaus ntseeg tuaj yeem ua rau cov txheej txheem ua tsis tiav, cov ntaub ntawv kev nyab xeeb hauv cov ntawv thov kev nyab xeeb (piv txwv li cov khoom siv hauv tsev).
3. UV-resistance mechanisms:
- Ntxiv: UV nqus (piv txwv li, benzotriazoles) Hloov ua lub zog auv rau hauv cov cua sov tsis muaj kuab lom
- Pigments thiab Colorants: Cov xim tsaus nti tuaj yeem nqus tau cua sov, thaum qee yam pigments (piv txwv li cov piganium) muaj kev cuam tshuam UV rays.
4. Cov kev txiav txim siab:
- Polymer hloov pauv: qee qhov plastics (piv txwv li, polyethylene: polyethylene) muaj ntau dua UV-rhiab dua li lwm tus (piv txwv li, pvc), tsim nyog siv cov qauv stabalizer.
- Ib puag ncig cov ntsiab lus: Cov cheeb tsam UV UV UV (piv txwv li, qhov kev xav tau sib npaug) thov kom muaj kev tiv thaiv.
5. Kev lag luam thiab ib puag ncig ntawm:
- Nqi Nyiaj Txiag Npaum Li Cas: UV Cov nqi ntxiv nce ntau lawm nqi tab sis nthuav cov khoom siv nyiaj, ua kom tau txais kev peev peev nyiaj ntev ntev.
- Rov ua dua tshiab: qee cov kauj vab stabilizers yuav ua rau cov txheej txheem ua dua tshiab, tabsis nce qib taw rau txoj kev sib luag nrog eco-phooj ywg.
6. Kuaj thiab Qauv:
- Cov kev sim siab nrawm nrawm: UV Chambers Simuling xyoo ntawm kev kis tau cov ntaub ntawv sib ntsib durabilmarks ua ntej kev ua lag luam tso tawm.
Hauv kev xaus, UV tiv taus yog qhov tseem ceeb rau kev tswj hwm txoj haujlwm thiab kev ua kom muaj kev ua kom zoo nkauj thiab cov khoom siv tsim nyog tsim qauv rau ib puag ncig thiab cov kev xav tau.
