Hauv peb lub neej niaj hnub, kev sib txuas yas muab kev pabcuam rau peb. Yog li ntawd, rau cov khoom siv tsis siv, peb yuav tsum nqa tawm kev khaws cia, tsis yog khoom kim heev thiab pov tseg. Tom ntej no, cia's qhia qee cov ntsiab lus tseeb ntawm daim ntawv thov thiab kev saib xyuas ntawm cov khoom.
Thaum peb khaws cov khi, peb yuav tsum khaws cia rau hauv qhov chaw qhuav thiab ntxoov ntxoo kom tsis txhob kov cov kua qaub thiab alkali organic solvents. Ntxiv mus, cov khoom no yuav tsum tau muab tso rau hauv flexion thiab txuas ntxiv yam tsis muaj extrusion lossis expansion. Yog tias lub sijhawm khaws cia ntev dhau lawm, peb yuav tsum nqa tawm dov, Cov khoom no tsis tuaj yeem ua pwm tom qab qhov kev tso kawm ntev, thiab cov khoom no tuaj yeem xaiv tau zoo raws li cov kev xav tau sib txawv thiab cov qauv tseeb. Tsis tas li ntawd, cov khoom no muaj cov qauv kev thov zoo, uas yuav cuam tshuam qhov sib txawv ntawm cov ductility thiab kev txhawb nqa ntawm txoj hlua khi raws li cov khoom siv, thiab txawm tias tawg.
Nws tseem yuav tsum tau muab sau tseg tias yog tias cov khoom puas nyob rau hauv tag nrho cov txheej txheem ntawm daim ntawv thov, peb yuav tsum tam sim ntawd nrhiav rau cov laj thawj thiab nqa tawm txij nkawm kom tsis txhob muaj kev phiv.
