Ua ntej, txoj kev kuaj xyuas thiab kev lav phij xaj:
Cov kev kuaj no yog ib qho kev sim tshuaj tshawb fawb uas muaj tag nrho cov khoom sib txawv hauv cov tsev kawm ntawv, Factories, thiab cov koom haum tshawb nrhiav.
Lub tsev kawm ntawv yog qhov kev qhia rau cov menyuam kawm ntawv rau kev sim tshuaj tshawb fawb, thiab lwm tus yog ib qho kev tshawb fawb tshawb fawb txog kev tshawb fawb.
Lub Hoobkas muaj chav kuaj thiab ib chav sim haujlwm. Cov kev kuaj laboratory tau ua tiav rau kev soj ntsuam ntawm cov khoom tiav thiab cov khoom tiav thaum tiav hauv cov txheej txheem. Lub Hauv Paus Tshuaj Tsev Kawm Ntawv (Central Laboratory) yog lub luag hauj lwm rau kev ntsuam xyuas cov ntaub ntawv raw khoom thiab kev tshuaj xyuas cov khoom ua haujlwm. Nws kuj lees paub txog kev tshawb nrhiav, kev txhim kho, kev ua haujlwm txhawb ntxiv, thiab kev npaj thiab kev txhim kho ntawm cov txheej txheem siv hauv cov kev sim laboratory.
Ntxiv nrog rau kev ua haujlwm kev sim cov kev tshawb fawb tshawb fawb, laboratory laboratory ntawm cov koom haum tshawb fawb tseem tshawb xyuas kev tshawb fawb ntawm kev tshawb fawb chemistry.
Thib ob, kev tsim kom muaj kev tsim kom muaj kev kuaj kom haum:
Raws li cov kev xav tau ntawm kev sim ua haujlwm, kev kho kom zoo nkauj nrog rau cov cuab yeej muaj nuj nqis heev thiab ntau yam tshuaj, nrog rau cov tshuaj thiab cov tshuaj phem. Tsis tas li ntawd, cov pa roj carbon monoxide los yog vapors raug ntau los ntawm kev ua haujlwm. Yog li, yuav tsum muaj kev tshwj xeeb rau cov qauv vaj tse, ib puag ncig, thiab vaj tse nyob hauv chav kuaj, uas yuav tsum raug suav nrog thaum npaj los tsim ib qho kev kuaj tshiab lossis kho dua tshiab ntawm ib qho kev kuaj sim.
Cov chav kuaj mob muaj cais ua peb pawg: cov kev ntsuas qhov ntsuas, cov chaw soj ntsuam tshuaj tshuaj, thiab chaw pabcuam (chaw ua haujlwm, chaw cia, cov thooj av, thiab lwmyam).
Lub chaw soj ntsuam mob yuav tsum ceev faj ntawm plua plav, haus luam yeeb, suab nrov thiab qhov chaw ntawm kev co. Chav kuaj xyuas yuav tsum yog li ntawd tsis yog nyob ze cov tsheb ciav hlau, chav boiler, tshuab chav ua haujlwm thiab kev cob qhia ntau tshaj (tshwj tsis yog kev kuaj laboratory). Yuav kom tswj tau cov huab cua zoo, nws yuav tsum yog feem ntau yog sab qaum teb-sab qab teb.
