ABS cov ntawv (acrylonitrile-butadiene-styrene copolymer sheets) kuj tsis muaj zog tiv thaiv ultraviolet (UV) lub teeb nyob rau sab nraum zoov, yog li qee qhov kev ntsuas yuav tsum tau coj los txhim kho lawv cov kev tiv thaiv UV. Cov hauv qab no yog ob peb txoj hauv kev tiv thaiv UV:
1. Ntxiv UV absorbers thiab stabilizers
UV absorbers: cov tebchaw xws li benzophenones (xws li UV-531), cov additives no tuaj yeem nqus tau UV rays thiab hloov lawv mus rau qhov tsis muaj cua sov, yog li tiv thaiv ABS boards los ntawm UV puas.
UV stabilizers: xws li HALS (Hindered Amine Light Stabilizers), uas tiv thaiv photodegradation thiab txuas ntxiv lub neej kev pab cuam ntawm ABS boards feem ntau los ntawm ntxiab dawb radicals.
2. Kev kho deg txheej
Txheej saum npoo ntawm ABS daim ntawv nrog ib txheej uas muaj UV tsis kam, xws li txheej uas muaj UV absorbers. Cov txheej no tuaj yeem thaiv cov UV rays ncaj qha rau ntawm daim ntawv ABS, yog li ua rau cov txheej txheem kev laus qeeb.
Cov txheej txheej saum npoo feem ntau yog siv rau kev siv sab nraum zoov xws li awnings, canopies, thiab lwm yam uas tsis raug tshav ntuj tsis tu ncua.
3. Cov khoom sib xyaw thiab kev hloov kho
ABS tau hloov kho los ntawm kev sib xyaw nrog cov polymers uas muaj kev tiv thaiv UV zoo, xws li fluoropolymers (xws li PVDF). Txoj kev hloov kho no tuaj yeem txhim kho UV tiv thaiv ntawm ABS pawg thawj coj saib, thaum tswj hwm nws qhov kev ua tau zoo tshaj plaws.
Kuj tseem xav txog kev sib xyaw nrog cov khoom siv nanoparticles (piv txwv li, titanium dioxide nanoparticles, zinc oxide nanoparticles), uas muaj UV tiv thaiv zoo heev thiab tuaj yeem txhim kho UV tiv thaiv ntawm ABS boards.
4. Tsim thiab installation optimization
Thaum tsim thiab txhim kho ABS panels, sim zam lawv qhov ncaj qha raug tshav ntuj ntev ntev. Kev tiv thaiv UV tuaj yeem txo qis los ntawm kev tsim lub hnub ci ntsa iab thiab kho lub kaum sab xis.
Tsis tu ncua tshuaj xyuas thiab tuav ABS panels los kho cov teeb meem xws li kev puas tsuaj saum npoo thiab txheej flaking nyob rau hauv lub sij hawm kom tswj tau lawv cov UV zoo.
5. Xaiv cov khoom siv UV resistant ABS
Xaiv cov ntaub ntawv ABS ntawm kev ua lag luam uas tau kho rau UV tiv thaiv. Cov ntaub ntawv no tau ntxiv nrog cov tshuaj tiv thaiv UV uas tsim nyog los yog kev kho mob tshwj xeeb thaum lub sijhawm tsim khoom, yog li lawv muaj kev ua haujlwm zoo los tiv thaiv UV.
Hauv cov ntsiab lus, los ntawm kev ntxiv UV absorbers thiab stabilizers, kev kho deg txheej, cov khoom sib xyaw thiab kev hloov kho, tsim thiab txhim kho kom zoo, nrog rau kev xaiv ntawm UV-resistant ABS cov ntaub ntawv, UV-resistant kev ua tau zoo ntawm ABS panels nyob rau sab nraum zoov ib puag ncig tuaj yeem ua tau zoo heev. txhim kho thiab lawv lub neej kev pabcuam tuaj yeem txuas ntxiv.
