UPVC yeeb nkab fittings yog dav siv nyob rau hauv kev tsim kho kev lag luam vim lawv zoo heev zog xws li corrosion kuj, durability, thiab tsis tshua muaj txij nkawm. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xav txog qhov ua tau zoo ntawm UV tiv thaiv ntawm UPVC yeeb nkab fittings thaum lawv siv rau sab nraum zoov. Kab lus no yuav tham txog kev ua haujlwm ntawm UV tiv thaiv ntawm UPVC yeeb nkab fittings.
1. UV tsis kam yog dab tsi?
UV tsis kam yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev puas tsuaj los ntawm kev raug UV hluav taws xob los ntawm lub hnub. UV hluav taws xob tuaj yeem ua rau ntau yam kev puas tsuaj rau cov ntaub ntawv xws li fading, discoloration, cracking, thiab degradation.
2. Vim li cas UV tiv thaiv tseem ceeb rau UPVC yeeb nkab fittings?
UPVC yeeb nkab fittings feem ntau yog siv rau sab nraum zoov daim ntaub ntawv uas lawv raug tshav ntuj. Kev cuam tshuam rau UV hluav taws xob tuaj yeem ua rau UPVC yeeb nkab fittings kom degrade nyob rau lub sij hawm, ua rau kom txo cov kav ntev thiab kev ncaj ncees. Tsis tas li ntawd, kev degradation ntawm UPVC yeeb nkab fittings tuaj yeem ua rau xau, uas tuaj yeem ua rau muaj kev puas tsuaj rau ib puag ncig.
3. Cov yam ntxwv cuam tshuam rau UV tsis kam ntawm UPVC yeeb nkab fittings
Ntau yam tuaj yeem cuam tshuam rau UV tsis kam ntawm UPVC yeeb nkab fittings. Cov no suav nrog cov thickness ntawm cov khoom, xim ntawm cov khoom, thiab muaj UV stabilizers nyob rau hauv cov khoom. Cov ntaub ntawv tuab dua thiab cov xim tsaus feem ntau muab kev tiv thaiv UV zoo dua. Tsis tas li ntawd, lub xub ntiag ntawm UV stabilizers tuaj yeem txhim kho UV tiv thaiv ntawm UPVC yeeb nkab fittings.
4. Kev sim cov txheej txheem rau UV tsis kam ntawm UPVC yeeb nkab fittings
UV tiv thaiv ntawm UPVC yeeb nkab fittings tuaj yeem kuaj tau siv ntau txoj hauv kev. Txoj kev siv ntau tshaj plaws yog Xenon arc test, uas simulates raug tshav ntuj los ntawm kev nthuav tawm cov khoom rau UV hluav taws xob nyob rau hauv kev tswj xyuas. Lwm txoj hauv kev suav nrog QUV kuaj thiab kuaj UV-B.
5. Qhov tseem ceeb ntawm kev xaiv UPVC yeeb nkab fittings nrog zoo UV tsis kam
Xaiv UPVC yeeb nkab fittings nrog zoo UV tsis kam yog qhov tseem ceeb rau kev ua kom lawv lub sijhawm ntev thiab kev ncaj ncees. UPVC yeeb nkab fittings uas tsis muaj kev tiv thaiv UV zoo tuaj yeem degrade lub sijhawm, ua rau cov dej xau thiab kev puas tsuaj rau ib puag ncig ib puag ncig. Qhov no tuaj yeem ua rau raug nqi kho thiab hloov cov fittings.
Hauv kev xaus, UV tsis kam yog qhov tseem ceeb rau kev txiav txim siab thaum xaiv UPVC yeeb nkab fittings rau kev siv sab nraum zoov. Lub thickness ntawm cov khoom, xim ntawm cov khoom, thiab muaj cov UV stabilizers yog txhua yam uas yuav cuam tshuam rau UV tsis kam ntawm UPVC yeeb nkab fittings. Kev sim cov txheej txheem xws li Xenon arc xeem tuaj yeem siv los ntsuas UV tsis kam ntawm UPVC yeeb nkab fittings. Xaiv UPVC yeeb nkab fittings nrog zoo UV tsis kam yog qhov tseem ceeb rau kev ua kom lawv lub sijhawm ntev thiab kev ncaj ncees.
