Hauv kev lag luam sab hauv niaj hnub thiab cov khoom siv kho kom zoo nkauj, ib qho ntawm cov kev sib tw tseem ceeb tshaj plaws yog ua kom lub sijhawm ntev - xim ruaj khov ntawm cov ntawv zoo nkauj. Raws li cov khoom siv saum npoo av rau laminate flooring, chav ua noj txee, thiab rooj tog hauv chaw ua haujlwm, daim ntawv no yog lub luag haujlwm rau kev zoo nkauj ntawm ntau lab lub tsev thiab chaw ua haujlwm. Txawm li cas los xij, qhov teeb meem tsis tu ncua yog qhov nyiam ntawm cov qauv tsim no kom ploj lossis tsis muaj xim thaum raug lub teeb ntuj, tshwj xeeb tshaj yog nyob rau hauv cov chav nrog lub qhov rais loj lossis cov hnub ci siab. Qhov kev tiv thaiv rau fading no paub nyob rau hauv kev lag luam raws li lightfastness, thiab nws tau dhau los ua ib qho tseem ceeb zoo metric uas txawv cov khoom hwm los ntawm kev siv nyiaj txiag. Rau cov tuam ntxhab thiab cov muag khoom, kev tswj xyuas qhov kev ruaj ntseg no tsis yog tsuas yog kev txhawj xeeb zoo nkauj xwb tab sis yog ib qho tseem ceeb ntawm cov khoom ruaj khov thiab lub koob npe nrov. Thaum tus neeg siv khoom nqis peev hauv qhov siab - cov rooj tog zaum kawg, lawv cia siab tias cov ntoo lis lossis cov qauv pob zeb yuav zoo li nplua nuj thiab zoo li ib xyoo caum tom qab nws tau ua nyob rau hnub ntawm kev yuav khoom, tsis hais txog kev ntxhov siab ib puag ncig.
Ua kom tiav qib siab ntawm cov xim ruaj khov no pib ntawm qib molecular nrog kev xaiv ntawm cov khoom siv raw, tshwj xeeb yog cov xim siv hauv cov txheej txheem luam ntawv. Cov ntaub ntawv kho kom zoo nkauj feem ntau siv cov pa luam yeeb uas tuaj yeem tawg sai sai nyob rau hauv kev ua phem ntawm ultraviolet hluav taws xob. Txhawm rau tiv thaiv qhov no, cov tuam txhab siab - kawg siv tshwj xeeb, lub teeb - cov xim tiv thaiv uas tau tsim tshwj xeeb kom ruaj khov thaum raug UV lub zog. Thaum cov neeg ua haujlwm no -qib pigments sawv cev rau tus nqi pib ntau dua, lawv yog ib qho kev nqis peev tseem ceeb rau cov khoom lag luam rau kev siv mus sij hawm ntev -. Tsis tas li ntawd, chemistry ntawm daim ntawv hauv paus nws tus kheej plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv tsis muaj xim. Ntau lub tuam txhab tam sim no hloov mus rau kev siv cov kua qaub- cov ntaub ntawv dawb. Cov ntawv sau ib txwm muaj peev xwm muaj cov kua qaub seem ntawm cov txheej txheem pulping uas ua rau cov khoom daj los yog ua rau lub sij hawm, cov nyhuv hu ua thermal lossis tshuaj lom neeg laus. Los ntawm kev siv cov kua qaub-dawb substrates, daim ntawv tuav nws qhov nruab nrab dawb tshuav nyiaj li cas, kom ntseeg tau tias cov suab nrov ntawm cov qauv luam tawm nyob twj ywm thiab tsis muaj tseeb los ntawm cov khoom siv tom qab.
Tshaj li tus cwj mem thiab ntawv, cov kab thib ob ntawm kev tiv thaiv yog nyob rau hauv cov txheej txheem impregnation, qhov twg cov ntawv kho kom zoo nkauj yog kho nrog cov cob tshwj xeeb, feem ntau melamine. Nyob rau hauv ib qho chaw tsim khoom zoo - zoo, cov resin no ua ntau dua li cov neeg ua kom tawv nqaij; nws ua hauj lwm raws li ib tug tiv thaiv barrier rau cov luam ntawv tsim. Ib qhov dej -formulated melamine resin tuaj yeem tsim los lim tawm ib feem tseem ceeb ntawm UV spectrum ua ntej nws puas mus txog txheej xim. Txhawm rau txhim kho qhov kev tiv thaiv no, cov tuam txhab lag luam siab heev feem ntau koom nrog cov kua UV absorbers ncaj qha rau hauv cov dej da dej. Cov tshuaj additives no ua qhov tseem ceeb ua qhov siab -SPF tshuaj pleev thaiv hnub rau cov rooj tog zaum saum npoo, absorbing thiab dissipating teeb meem hluav taws xob raws li tsis muaj teeb meem thaum tshav kub kub. Rau B2B distributors thiab cov kws tsim rooj tog, kev lag luam tso siab rau cov txheej txheem kev sim uas hu ua xiav wool nplai los ntsuas qhov kev tiv thaiv no. Kev ntsuam xyuas ntawm 6 lossis siab dua ntawm qhov ntsuas no feem ntau suav hais tias yog tus qauv ntsuas rau cov rooj tog zaum zoo thiab hauv pem teb, muab qhov ntsuas ntsuas tau tias cov khoom tuaj yeem tiv taus lub teeb hnyav yam tsis muaj qhov cuam tshuam loj.
Qhov kev thov rau siab -cov ntaub ntawv zoo nkauj ruaj khov yog tam sim no tau tsav los ntawm kev hloov pauv thoob ntiaj teb hauv cov qauv kev tsim vaj tsev. Niaj hnub nimno cov tsev nyob thiab kev lag luam nce ntxiv nthuav dav qhib- cov phiaj xwm tsim tshwj xeeb los ntawm loj, hauv pem teb- mus rau - qab nthab iav facades thiab skylights. Txawm hais tias cov yam ntxwv no ua rau lub teeb pom kev zoo tshaj plaws thiab txhim kho lub qhov dej zoo - yog ntawm cov neeg nyob, lawv kuj raug cov chaw sab hauv rau qhov tsis tau pom dua los ntawm UV hluav taws xob. Yog li ntawd, dab tsi yog ib lub niche technical specification tau tam sim no dhau los ua kev lag luam tseem ceeb. Los ntawm kev nqis peev nyob rau hauv cov khoom siv tshuaj lom neeg zoo tshaj plaws, cov txheej txheem resin siab heev, thiab kev sim nruj nruj, cov tuam txhab tuaj yeem muab cov khoom lag luam uas khaws nws cov kev zoo nkauj zoo nkauj raws li qhov xav tau tshaj plaws ntawm ib puag ncig. Qhov kev tiv thaiv zoo rau cov xim ruaj khov no tsis yog tsuas yog tiv thaiv fading; nws txo qis qhov zaus ntawm cov neeg siv khoom tsis txaus siab thiab thov rov qab los, thaum kawg tsim kev ntseeg siab ntev ntev thiab muaj kev sib tw muaj zog hauv kev ua lag luam thoob ntiaj teb. Hauv cov ntsiab lus, kev tshawb fawb ntawm lightfastness yog qhov tso cai rau cov khoom siv kho kom zoo nkauj niaj hnub los txuas qhov sib txawv ntawm kev zam ib ntus thiab kev tsim vaj tsev zoo.
