Kev siv
Raws li cov kuab tshuaj, tetrachloroethane ua pov thawj tias yog ib qho khoom muaj nqis. Nws cov kuab tshuaj zoo heev ua rau nws zoo tagnrho rau cov tshuaj tiv thaiv, kev tsim khoom thiab kev siv tshuaj ntxuav. Txawm hais tias koj xav tau tshem tawm impurities, yaj cov teeb meem, los yog huv si, tetrachloroethane yog koj cov lus teb. Nws cov kev ua haujlwm siab-potency thiab siab purity ua kom pom cov txiaj ntsig zoo txhua lub sijhawm.
Sib nrug los ntawm nws cov khoom hnyav, tetrachloroethane kuj tseem siv tau los ua cov extractant zoo hauv ntau yam lag luam. Nws lub peev xwm los cais thiab mloog cov tshuaj tshwj xeeb ua rau nws yog ib qho cuab yeej tseem ceeb hauv cov chaw kuaj tshuaj thiab kev tshawb fawb. Qhov muaj peev xwm muaj zog no ua rau cov kws tshawb fawb thiab cov kws tshaj lij tau txais cov ntsiab lus ntshiab thiab cov roj tseem ceeb uas tuaj yeem txhim kho cov tshuaj tshiab thiab lwm yam kev tshawb pom tseem ceeb.
Tsis tas li ntawd, tetrachloroethane tau ua pov thawj tias yog tshuaj tua kab thiab tshuaj tua kab mob zoo heev. Nws toxicity ua kom tshem tawm cov kab tsuag tsis xav tau thiab cov nroj tsuag tawv tawv, muab kev daws teeb meem rau kev ua liaj ua teb sib tw. Cov cuab yeej no ua rau tetrachloroethane yog ib feem tseem ceeb ntawm cov tshuaj tua kab thiab tshuaj tswj cov nroj tsuag siv hauv vaj, ua liaj ua teb thiab lwm qhov chaw ua liaj ua teb.
Txawm hais tias tetrachloroethane muaj ntau yam zoo, nws yuav tsum tau ua tib zoo saib xyuas vim nws muaj peev xwm txaus ntshai. Kev cuam tshuam rau qee yam tshuaj (xws li hlau sodium thiab potassium) tuaj yeem ua rau tawg thiab kev sib cuag nrog dej tuaj yeem ua rau decomposition. Txawm li cas los xij, thaum siv lub luag haujlwm raws li cov lus qhia kev nyab xeeb, tetrachloroethane tuaj yeem yog ib qho khoom muaj nqis heev hauv kev ua tiav koj cov txiaj ntsig xav tau.
Hauv kev xaus, Tetrachloroethane yog cov khoom siv ntau yam thiab siv tau zoo tshaj qhov kev cia siab. Txawm hais tias koj xav tau cov kuab tshuaj txhim khu kev qha, muaj txiaj ntsig zoo los yog tshuaj tua kab / tshuaj tua kab muaj zog, tetrachloroethane tuaj yeem ua tau raws li koj xav tau. Nws zoo heev solvency, extractability, thiab zoo tiv thaiv kab tsuag thiab nroj tsuag ua rau nws yog ib qho tseem ceeb xaiv rau ntau yam kev lag luam thiab kev ua liaj ua teb daim ntaub ntawv. Tso siab rau tetrachloroethane kom xa cov txiaj ntsig zoo dua thaum ua kom muaj kev nyab xeeb thiab kev ntseeg siab.
