Laser txiav yog siv lub zog siab ceev ceev laser beam rau irradiate lub workpiece, kom cov irradiated cov ntaub ntawv yuav sai sai yaj, vaporize, ablate los yog mus txog lub ignition point. Nyob rau tib lub sij hawm, nrog kev pab los ntawm high-ceev cua khiav coaxial nrog lub beam, cov khoom molten yuav raug tshuab mus, thiaj li mus txiav lub workpiece.
Galvanized steel ntawv yog cov khoom siv dav siv hauv kev tsim khoom. Galvanized steel ntawv yog coated nrog hlau zinc los tiv thaiv corrosion ntawm cov ntawv hlau thiab ua kom nws lub neej ntev. Nws yog tsuas yog siv rau cov khoom siv hauv tsev plhaub, lub qhov cub hluav taws xob, cov khoom siv hauv chav ua noj, thiab lwm yam khoom siv no puas tsim nyog rau kev txiav nrog laser txiav tshuab?
Feem ntau hais lus, rau galvanized steel phaj, laser txiav tshuab tau yooj yim txiav, thiab feem ntau cov organic thiab inorganic khoom siv tau. Txhua yam ntawm cov ntaub ntawv hlau feem ntau siv hauv kev tsim khoom lag luam tuaj yeem txiav yuav luag tsis muaj teeb meem dab tsi nws muaj.
Hauv cov txheej txheem ntawm kev ua cov ntawv galvanized, auxiliary gas xav tau ntxiv. Lub purity thiab siab ntawm cov pa pab cuam cuam tshuam qhov zoo ntawm cov ntawv txiav seem. Lub purity ntawm oxygen siv rau kev txiav yuav tsum ntau tshaj 99.6 feem pua. Thaum lub purity ntawm oxygen siv rau kev txiav yog siab dua, qhov roughness thiab zoo ntawm txiav galvanized daim ntawv seem yog siab dua. Tau kawg, tus nqi txiav kuj nce ntxiv, thiab purity ntawm nitrogen thaum txiav yuav tsum siab dua 99.5 feem pua. Txhim kho qhov purity ntawm nitrogen kom ntseeg tau tias qhov kev txiav yuav tsis hloov xim thaum txiav cov ntawv galvanized.
