Chromium (Cr) Element

 

Chromium yog ib yam khoom siv hlau uas tsim cov yeeb yaj kiab tiv thaiv ntawm cov hlau nto. Nyob rau hauv chromium - muaj hlau, chromium reacts nrog oxygen los tsim ib tug ntom chromium oxide (Cr₂O₃) tiv thaiv zaj duab xis ntawm steel nto. Cov yeeb yaj kiab no ruaj khov heev thiab tuaj yeem cais cov hlau los ntawm cov xov xwm corrosive sab nraud, xws li cov dej hiav txwv hauv dej hiav txwv, cov dej noo thiab oxygen hauv cov huab cua. Piv txwv li, stainless hlau muaj cov feem ntau ntawm cov chromium, ua rau nws muaj kev tiv thaiv corrosion zoo los ntawm kev tsim nyog ntawm no chromium oxide tiv thaiv zaj duab xis nyob rau hauv qhov chaw ntub dej lossis thaum sib cuag nrog cov kua dej tsis muaj zog.

 

Thaum no chromium oxide tiv thaiv zaj duab xis yog me ntsis puas, nyob rau hauv ib tug oxygen - nplua nuj ib puag ncig, lub chromium keeb tuaj yeem txhawb kev kho tus kheej ntawm cov yeeb yaj kiab tiv thaiv. Vim hais tias cov chromium nyob rau hauv cov hlau tuaj yeem hnov ​​​​mob sai sai nrog cov pa kom rov tsim cov chromium oxide, ua kom tiav qhov kev puas tsuaj ntawm cov yeeb yaj kiab tiv thaiv, thiab yog li txuas ntxiv ua lub luag haujlwm tiv thaiv thiab tiv thaiv cov khoom corrosive los ntawm eroding sab hauv ntawm cov hlau.

 

Aluminium (Al) Element

 

Aluminium kuj tuaj yeem tsim cov yeeb yaj kiab tiv thaiv hauv cov hlau. Thaum cov hlau raug huab cua lossis lwm qhov chaw oxidizing, aluminium reacts nrog oxygen los ua ib qho txhuas oxide (Al₂O₃) tiv thaiv zaj duab xis. Aluminium oxide muaj siab hardness, siab melting point, thiab zoo tshuaj stability thiab yog ib tug zoo heev tiv thaiv txheej. Nyob rau hauv ib puag ncig kub, qhov zoo ntawm cov yeeb yaj kiab tiv thaiv no yog pom tseeb dua. Piv txwv li, nyob rau hauv cov txheej txheem ntawm ib co high-temperature industrial furnaces, lub aluminium oxide tiv thaiv zaj duab xis nyob rau saum npoo ntawm txhuas - uas muaj hlau yuav zoo tiv taus kub oxidation thiab kub corrosion.

 

Zoo ib yam li cov yeeb yaj kiab tiv thaiv tsim los ntawm chromium, aluminium oxide tiv thaiv zaj duab xis kuj muaj qee qhov kev kho tus kheej. Thaum cov yeeb yaj kiab tiv thaiv ib nrab puas lawm, cov atoms nyob ib puag ncig ntawm txhuas yuav txuas ntxiv ua rau cov pa oxygen los hloov kho aluminium oxide nyob rau hauv qhov chaw puas, tswj kev ncaj ncees ntawm cov yeeb yaj kiab tiv thaiv thiab yog li ua kom muaj kev tiv thaiv corrosion ntawm cov hlau.

Silicon (Si) Element

 

Cov yeeb yaj kiab tiv thaiv tsim los ntawm silicon ntawm cov hlau yog tsim los ntawm kev ua pa nrog oxygen los ua silicon dioxide (SiO₂). Cov yeeb yaj kiab silicon dioxide tiv thaiv yog iav - zoo li cov khoom siv tshuaj lom neeg zoo. Hauv qee qhov tshwj xeeb corrosive ib puag ncig, xws li cov uas muaj cov kua qaub los yog qhov chaw kub oxidizing, silicon dioxide tiv thaiv zaj duab xis tuaj yeem tiv thaiv cov khoom corrosive los ntawm kev sib cuag nrog cov hlau. Piv txwv li, hauv cov khoom siv tshuaj, kev siv cov hlau uas muaj qhov tsim nyog ntawm silicon tuaj yeem tiv thaiv kev yaig ntawm cov tshuaj acidic vim tias silicon dioxide tiv thaiv zaj duab xis tuaj yeem tiv thaiv acidic ions los ntawm kev nkag mus thiab corroding cov hlau.

 

Txawm li cas los xij, cov yeeb yaj kiab tiv thaiv tsim los ntawm silicon yog nkig. Nws tuaj yeem tawg thaum raug kev ntxhov siab lossis kev hloov pauv kub loj. Tab sis tsuav yog muaj cov pa oxygen txaus nyob rau hauv ib puag ncig, cov khoom silicon tseem tuaj yeem rov tsim dua silicon dioxide ntawm qhov tawg thiab rov ua haujlwm ntawm kev tiv thaiv zaj duab xis rau qee qhov.
