Kev lag luam chemical yog ib qho kev lag luam tshwj xeeb. Cov khoom lag luam pov hwm kev ua haujlwm siv los ntawm cov neeg ua haujlwm kuj tseem muaj kev txawj ntse. Muaj ntau yam khoom pov hwm kev ua haujlwm nyob rau hauv kev ua lag luam uas tsim nyog rau kev lag luam tshuaj. Piv txwv li, kev nyab xeeb ntawm kev lag luam tshuaj. Nkawm khau, muaj qee yam yuav tsum tau ua, xws li kev ua haujlwm zoo rau cov roj, smashing, kub kub, acid thiab alkali thiab rwb thaiv tsev.
Qee cov neeg ua haujlwm tshuaj lom neeg hauv kev lag luam chemical tau koom nrog kev ua haujlwm kub kub. Raws li txoj cai, lawv tuaj yeem hnav khau kev nyab xeeb nrog qhov kub thiab txias tiv thaiv lawv ob txhais taw ntawm qhov kub thiab txias, sparks thiab kub hnyiab. Vim tias qhov kub thiab txias tiv thaiv kev nyab xeeb khau yog ua los ntawm cov khau siab kub thiab cov tawv tawv, lawv tiv thaiv ob txhais taw los ntawm kev kub siab ua haujlwm xws li cov hlau molten thiab raug kub hnyiab los ntawm kub kom tsis txhob raug mob.
Yog tias qee lub tuam txhab tshuaj lom neeg tau koom nrog cov roj refining, lawv ua haujlwm hauv kev cob qhia nrog cov roj av lossis cov tar refining txhua hnub. Yog tias hnav cov khau kev nyab xeeb nrog cov roj ua haujlwm, nws tuaj yeem txo cov roj paug thiab txo qhov kev pheej hmoo ntawm kev swb thaum cov neeg ua haujlwm ua haujlwm. Roj-resistant khau kev nyab xeeb yog khau kev nyab xeeb uas siv cov khoom siv los tiv thaiv roj rau ntawm ib sab thiab sab sauv, tsis yaj los ntawm cov roj, muaj cov nyhuv zoo heev ntawm cov roj, thiab tsis plam ntawm cov roj av.
Qee lub tuam txhab tshuaj hauv kev lag luam tshuaj feem ntau tsim cov khoom siv tshuaj. Cov tshuaj no feem ntau muaj feem xyuam rau cov tshuaj acid-alkaline, thiab cov neeg ua haujlwm tshuaj hnav cov khau tiv thaiv acid thiab alkali tiv thaiv kev nyab xeeb tuaj yeem tiv thaiv lawv txhais taw los ntawm kev puas tsuaj tshuaj. Vim tias cov kua qaub thiab alkali tiv thaiv kev nyab xeeb khau yog khau kev nyab xeeb uas muaj kua qaub thiab alkali tsis kam thiab siv los tiv thaiv ko taw thiab tiv thaiv cov kua qaub thiab alkali tshuaj nyob rau hauv cov kua qaub thiab alkali thiab corrosive ua hauj lwm ib puag ncig.
Kev nyab xeeb kev nyab xeeb yog qhov kev txhawj xeeb tshaj plaws hauv kev tsim tshuaj lom neeg. Tej zaum nws yog qhov tsis txhob txwm ua, vim qee yam tsis paub, nws yuav ua rau muaj kev puas tsuaj rau cov neeg ua haujlwm tshuaj lom neeg, yog li nws yog qhov tsim nyog rau cov neeg ua haujlwm chemical hnav tiv thaiv kev ua haujlwm thaum lub sijhawm ua haujlwm. khau.
Qhov tseem ceeb ntawm kev tsim khoom nyab xeeb yog nyob rau hauv kev tiv thaiv lossis tshem tawm cov teeb meem cuam tshuam rau cov neeg ua haujlwm kev noj qab haus huv thiab tshwm sim ntawm ntau yam xwm txheej, ua kom muaj kev nyab xeeb ntawm tib neeg lub neej thiab khoom vaj khoom tsev, thiab ua kom muaj kev tsim khoom ib txwm muaj. Yog li ntawd, nws yog ib qho tsim nyog rau cov neeg ua haujlwm hnav nkawm khau kom ruaj ntseg kom tsis txhob muaj teeb meem ua ntej lawv tshwm sim.
