Qhov ntom ntom ntawm cov hlau lead: kev tsom xam ntawm lub cev thiab kev siv
Lead yog cov hlau uas muaj lub cev tshwj xeeb thiab yog siv rau hauv ntau hom kev lag luam. Hauv tsab xov xwm no, peb yuav ua tib zoo saib qhov ntom ntawm cov hlau lead, txheeb xyuas nws qhov tseem ceeb hauv ntau daim ntawv thov thiab piav qhia vim li cas nws tseem ceeb tshwj xeeb hauv kev lag luam tshuaj.
Qhov ntom ntawm cov txhuas thiab nws cov khoom siv lub cev
Qhov ceev ntawm cov hlau lead yog hais txog qhov loj ntawm cov hlau lead hauv ib chav tsev ntim, nrog rau tus nqi tshwj xeeb ntawm 11.34 g / cm3. Cov cuab yeej siab ceev no ua rau cov khoom siv tseem ceeb hauv ntau daim ntawv thov. Qhov ceev ntawm cov hlau lead yog ntau tshaj li tus lej tus nqi, nws qhia txog lub cev tseem ceeb ntawm cov hlau lead xws li nws qhov hnyav, zoo corrosion kuj thiab qis melting point (327.5 ° C).
Qhov ntom ntawm cov hlau lead hauv cov ntawv thov kev lag luam
Vim yog cov hlau lead ntau ntom ntom, nws tau siv dav hauv kev lag luam rau kev tsim cov khoom uas xav tau cov khoom hnyav. Piv txwv li, nyob rau hauv lub tshav pob ntawm kev tiv thaiv hluav taws xob, lub siab ceev ntawm cov hlau lead ua rau nws yog ib qho zoo tagnrho shielding khoom, zoo thaiv kev nkag mus ntawm X-rays thiab gamma rays. Hauv kev tsim cov roj teeb, cov roj ntsha lead-acid coj kom zoo dua cov hlau lead lub siab ceev thiab cov khoom siv hluav taws xob los muab lub zog ruaj khov.
Lead qhov ntom kuj tseem siv rau hauv kev tsim kho thiab kav dej hauv kev lag luam. Cov kav dej txhuas ib zaug tau siv dav hauv cov tshuab xa dej vim lawv qhov ntom ntom thiab corrosion-resistant zog. Raws li kev paub txog ib puag ncig tau nce ntxiv, cov kav hlau lead tau maj mam hloov los ntawm cov khoom siv zoo dua.
Environmental Impact ntawm Lead Density
Txawm hais tias qhov ntom ntawm cov hlau lead muab qhov zoo rau nws siv hauv ntau daim ntawv thov, qhov ntom ntawm cov hlau lead kuj txhais tau hais tias nws muaj feem cuam tshuam rau ib puag ncig. High-density lead pov tseg, yog tias tsis kho kom raug, tuaj yeem ua rau hnyav hlau paug ntawm cov av thiab dej, uas tuaj yeem cuam tshuam rau ecosystems thiab tib neeg kev noj qab haus huv. Yog li ntawd, kev nkag siab txog qhov ntom ntom thiab cov khoom sib txuas ntawm cov hlau lead yog qhov tseem ceeb rau kev txhim kho cov khoom pov tseg kom tsim nyog thiab kev ntsuas rov ua dua tshiab.

Qhov ntom ntawm txhuas tsis tsuas yog txiav txim siab nws lub cev lub cev, tab sis tseem cuam tshuam rau nws daim ntawv thov hauv kev lag luam thiab kev cuam tshuam ib puag ncig. Kev nkag siab txog qhov ntom ntom ntawm cov hlau lead thaum xaiv thiab siv cov khoom siv lead ua tuaj yeem pab txhim kho cov khoom tsim thiab kev siv thaum txo nws cov kev cuam tshuam ib puag ncig. Yog li ntawd, qhov ntom ntawm cov hlau lead yog qhov tseem ceeb uas yuav tsum tau ua tib zoo xav hauv ob qho tib si kev tsim khoom thiab kev tswj hwm ib puag ncig.
