Rolled tooj dag ntawv ci
Khoom Taw Qhia
Tooj liab yog ib qho alloy ntawm tooj liab thiab zinc, uas yog feem ntau hu ua tooj dag vim nws golden daj nto xim. Lub zinc hauv tooj dag ua cov khoom tawv thiab tiv thaiv ntau rauPuas Tsum, thaum cov khoom siv kuj muajIb tug zoo tensile lub zog. Lub tooj dag nyiaj ci ua los ntawmRiven hlau muaj qhov zoo nto moo ua tiav, ib daim ntawv tiaj tiaj thiab duab thiab zoo sib xws. Tooj dag ntawv ci yog feem ntau siv nyob rau hauv kev lag luam zoo nkauj vim nws cov khoom siv golden, raws li cov khoom siv tiv thaiv lossis cuam tshuam tsis kam, thiab raws li agasket khoomVim tias nws hnav tsis kam. Tooj dag kuj tseem siv hluav taws xob cua sov siv hluav taws xob vim nwsHluav taws xobCov khoom tiv thaiv tsis kam. Vim yog Sphericallub tsev ntawm cov dovtooj daj Ntawv ci, lub xeev muag muag thiab nyuaj tuaj yeem tswj tau los ntawm cov txheej txheem anealing, ua rau nws haum ntau rau ntau yam ntawm Cov ntawv thov.Cov Khoom Siv Hluav Taws Xob tseem tuaj yeem tsim cov ntawv ci tooj liab Hauv cov tuab tuab thiab dav dav raws li cov neeg siv khoom siv, yog li txo cov nqi tsim khoom thiab txhim kho kev ua haujlwm.
