Yam dab tsi yuav cuam tshuam qhov zoo ntawm cov xim hlau daim hlau

Cov xim hlau hlau feem ntau yog siv rau hauv cov hlau tsis muaj hlau smelters hauv metallurgical thiab fais fab kev lag luam (xws li tooj liab, zinc, txhuas, txhuas, thiab lwm yam) thiab muaj kev tiv thaiv corrosion kuj. Yog li dab tsi yam yuav ua rau qhov zoo ntawm cov xim hlau daim hlau? Cia wb mus saib ua ke.
1. Kub
Cov txheej txheem softens ntawm qhov kub thiab txias thiab nws yooj yim rau corroding qhov nruab nrab, nkag mus rau hauv lub substrate, ua kom cov pa oxygen hauv cov dej ntawm qhov kub thiab txias, thiab nce tus nqi corrosion ntawm qee qhov kub.
2. Lub substrate corrosion tshwm sim los ntawm noo noo txiav thiab kev puas tsuaj yog electrochemical corrosion, uas tsis yooj yim rau tsim corrosive roj teeb (xws li electrochemical circuits) nyob rau hauv cov av qis.
Yog hais tias qhov kub thiab txias sib txawv nruab hnub thiab hmo ntuj yog loj, condensation yuav tshwm sim thiab electrochemical corrosion yuav tshwm sim ntawm liab qab hlau. Tsis tas li ntawd, yog tias qhov sib txawv ntawm qhov kub thiab txias yog qhov loj, qhov txias thiab kub deformation ntawm cov txheej txheej yuav tshwm sim ntau zaus, yog li ua kom cov laus thiab so kom txaus. Coatings thiab lwm yam corrosive media tuaj yeem nkag mus rau hauv substrate yooj yim.
4. Lub sij hawm thiab kev siv ntawm lub hnub ci yog ib qho hluav taws xob nthwv dej, muab faib ua X-rays, ultraviolet rays, pom lub teeb, infrared rays, microwaves, thiab xov tooj cua tsis. Cov nthwv dej thiab xov tooj cua tsis muaj zog thiab tsis cuam tshuam nrog cov teeb meem. Infrared kuj tseem muaj lub zog qis, uas tso cai rau cov tshuaj sib txuas ntawm cov khoom yuav ncab thiab khoov, tab sis tsis tawg. Pom pom lub teeb muab nplua nuj xim rau txhua yam.
5. Ntog thiab acidity ntawm nag lossis daus Lub acidity ntawm nag xob nag cua yog undoubtedly tsis conducive rau corrosion kuj. Txawm li cas los xij, qhov no muaj ob qho kev cuam tshuam rau dej nag. Rau cov phab ntsa ntxhab thiab lub ru tsev panels, kev ua haujlwm ntawm sedimentation yog los ntxuav cov hlau phaj thiab ntxuav cov khoom siv corrosion ntawm qhov chaw. Corrosion feem ntau tshwm sim thaum lub caij los nag hnyav.
6. Cua kev taw qhia thiab ceev Cua kev taw qhia thiab ceev zoo ib yam li dej thiab feem ntau cuam tshuam. Qhov no yog ib qho kev sim ntawm cov khoom sib txuas, vim cua tuaj yeem txo qhov kev sib txuas thiab tso cai rau cov dej nag nkag mus rau sab hauv.
7. Corrosive deposits xws li chloride ions thiab sulfur dioxide muaj kev txhawb nqa ntawm corrosion. Cov sediments feem ntau tshwm sim ntawm ntug hiav txwv dej thiab hauv cov cheeb tsam uas muaj kuab paug loj heev (cov nroj tsuag fais fab, smelters, thiab lwm yam).
