Vim yog kev teeb tsa ntawm cov cua txias cua txias hauv cov chav pleev xim thiab kev cob qhia, Qhov tsim nyog rau kev tawg-pov thawj cua txias hauv thaj chaw pleev xim yog los ntawm cov laj thawj tseem ceeb hauv qab no:
Kev Tswj Kub Kub:
Txhawm rau txo qhov kev pheej hmoo ntawm hluav taws kub nyhiab tshwm sim los ntawm cov cua kub ntau dhau.
Tiv thaiv tawg:
Tsim kom muaj kev nyab xeeb thiab xis nyob ua haujlwm yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov chaw kaw xws li cov khw kho tsheb thiab cov chaw ua haujlwm me me. Cov cheeb tsam no feem ntau saturated nrog nplaim taws thiab cov pa tawg xws li cov xim vapors, hmoov av, thiab turpentine. Cov kuab tshuaj no, ua raws li cov xim thinner, evaporate sai sai tom qab txau. Thaum huab cua mus txog ib qho concentration ntawm cov pa roj, Nws yuav raug cuam tshuam rau kev tawg thaum ntsib qhov hluav taws kub los yog kub heev.
Li no, nyob rau hauv cov cheeb tsam no, tsis tsuas yog kev txwv nruj ntawm cov nplaim taws qhib qhov tseem ceeb, tab sis kuj siv ntawm Cov khoom siv hluav taws xob tawg. Qhov kev ceev faj no yog txhawm rau tiv thaiv qhov hluav taws kub ntawm cov pa hluav taws xob los ntawm cov hluav taws xob tsim tawm thaum lub sijhawm ua haujlwm., kev ua haujlwm, los yog kaw cov khoom siv hluav taws xob. Cov kev cai tam sim no los ntawm lub tuam tsev tua hluav taws hauv lub tebchaws tau txiav txim siab siv cov cua txias uas tawg tawg hauv cov chaw zoo li no kom ua raws li cov qauv kev nyab xeeb..
Cov cua txias uas tawg-pov thawj tau nce ua haujlwm nyob rau hauv ntau qhov chaw, hais txog tias kev tsim khoom nyab xeeb yog qhov tseem ceeb rau kev lag luam.
