Cov kev xa tawm ntawm PC cov qhov rais kho qhov rais puas tuaj yeem khaws cia siab dua 90% rau lub sijhawm ntev?
Hauv kev lag luam cov cuab yeej siv, cov cuab yeej ntse, thiab lwm yam, PC tshuab qhov rais dais lub luag haujlwm ntawm kev tiv thaiv sab hauv thiab ua kom pom tseeb meej. Lub sijhawm ntev kev ruaj ntseg ntawm lawv cov kev xa tawm ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom siv. Tab sis puas tuaj yeem hloov pauv ntawm PC txhua yam qhov rais tau khaws cia siab dua 90% rau lub sijhawm ntev? Qhov no yog nyob ntawm kev sib koom ua ke ntawm ntau yam xws li xaiv cov khoom siv, kev tswj cov txheej txheem, thiab kev siv tu.
Cov khoom siv PC nws tus kheej muaj lub teeb kis tau tus mob ze rau iav. Thawj lub teeb xa hluav taws xob ntawm cov khoom siv PC zoo tuaj yeem ncav cuag li 90%, uas yog lub hauv paus rau kev tswj xyuas lub teeb pom kev zoo nyob rau lub sijhawm ntev. Txawm li cas los xij, cov PCs zoo tib yam muaj qhov tsis txaus ntseeg, vim tias pawg ester thiab benzene rings nyob rau hauv lawv cov qauv molecular yog rhiab heev rau ultraviolet hluav taws xob. Kev raug lub teeb ntev ntev tuaj yeem ua rau muaj kev cuam tshuam oxidation, ua rau cov saw hlau molecular tawg thiab tsim cov khoom sib xyaw daj, yog li txo cov teeb pom kev zoo. Cov kev sim tau pom tias tom qab 3-5 xyoos ntawm kev siv sab nraum zoov, kev xa tawm ntawm cov khoom siv PC tsis kho yuav txo qis los ntawm 15% -30%, thiab nws yog qhov tsis yooj yim sua kom tswj tau qib ntau dua 90%.
Kev tawg ntawm cov khoom siv hloov kho tshuab muab qhov ua tau los daws qhov teeb meem no. Kev laus tiv thaiv PC tuaj yeem thaiv lub teeb ultraviolet thiab ncua tus nqi daj los ntawm kev ntxiv UV absorbers thiab lub teeb stabilizers. Hauv 1000 teev UV aging test, transmittance attenuation of aging resistant PC is much low than that of dog dig PC. Qhov tseem ceeb tshaj, cov cuab yeej tiv thaiv saum npoo, UV txheej tuaj yeem tsim cov txheej txheem tiv thaiv ntawm PC, uas tuaj yeem lim 99% ntawm UV rays.
Kev siv thev naus laus zis muaj qhov cuam tshuam loj heev rau lub sijhawm ntev kev ruaj ntseg ntawm lub teeb xa hluav taws xob. Yog tias muaj kev ntxhov siab sab hauv thaum lub sijhawm ua haujlwm PC, nws tuaj yeem ua rau qhov tsis sib xws ntawm cov saw hlau molecular, uas yuav tsis tsuas yog ua rau muaj kev sib tw, tab sis kuj ua rau kev ua haujlwm kho qhov muag tsis zoo nyob rau lub sijhawm. Tsis tas li ntawd, kev ua haujlwm siab lossis impurities hauv cov khoom siv raw yuav ua rau txo qis hauv kev xa tawm. Los ntawm kev ua kom zoo rau cov txheej txheem txhaj tshuaj molding thiab extrusion, tswj kev ua haujlwm kub li ntawm 300 ℃, thiab zam kev sib cuag nrog cov hlau ions xws li tooj liab thiab hlau, qhov kev pheej hmoo ntawm cov khoom degradation tuaj yeem raug txo, kom ntseeg tau tias pib lub teeb xa mus ntev thiab ruaj khov mus ntev.
Kev siv ib puag ncig thiab kev saib xyuas yog qhov tseem ceeb sib npaug. Hauv thaj chaw ntug dej hiav txwv uas muaj ntsev ntau los yog muaj kuab paug ib puag ncig, dej nag thiab tshuaj lom neeg tuaj yeem ua rau PC aging. Hauv kev saib xyuas txhua hnub, siv cov cuab yeej nyuaj rau kev tu yuav yooj yim ua rau khawb thiab kuj txo cov teeb pom kev zoo. Xaiv cov qib kev tiv thaiv tsim nyog rau ib puag ncig thiab siv cov ntaub mos muag tuaj yeem ua kom lub sijhawm txij nkawm ntawm lub xeev siab.
Hauv cov ntsiab lus, seb lub teeb xa hluav taws xob ntawm PC tshuab qhov rais tuaj yeem khaws cia siab dua 90% rau lub sijhawm ntev yog nyob ntawm seb puas siv cov khoom siv los tiv thaiv kev laus thiab kev tiv thaiv UV txheej, txawm tias kev ntxhov siab sab hauv yog tswj los ntawm kev ua haujlwm zoo, thiab seb kev saib xyuas puas yog ua ke nrog cov yam ntxwv ntawm ib puag ncig. Nyob rau ntawm qhov chaw ntawm lub rooj sib tham cov qauv khoom, zoo craftsmanship, thiab kev tu kom zoo, PC mechanical windows tuaj yeem ua tiav lub hom phiaj no, muab kev lees paub rau lub sijhawm ntev kev lag luam txhim khu kev qha ntawm cov khoom siv. Nrog rau kev nce qib ntawm cov khoom siv thev naus laus zis tas mus li, lub sijhawm txij nkawm ntawm kev xa tawm siab yuav txuas ntxiv mus ntxiv.
