Cov hnab ntim khoom muaj xws li cov dej khov (acetic acid, ethanol, n-hexane), cov kua zaub paug, hnyav hlau, tshuaj dawb. Evaporation residue yog reflected nyob rau hauv kev siv cov zaub mov ntim hnab cov ntaub ntawv ntawm vinegar, wine, roj thiab lwm yam kua dej los nag residue, tseem hnyav hlau, residues thiab hnyav hlau yuav muaj teebmeem rau tib neeg kev noj qab haus huv, ntxiv residue yuav ncaj qha rau cov xim ntawm cov zaub mov, xyab, Saj thiab lwm yam zaub mov zoo.
Kev ua kom ploj zuj zus
Nyob ntawm seb hom khoom degradation, muab faib ua photodegradable, biodegradable, environmentally degradable. Degradation yog lub peev xwm ntawm cov khoom yuav tsum tau txais los ntawm qhov chaw tom qab nws tau raug pov tseg. Yog hais tias nws degradability zoo, lub hnab yuav tawg, cais thiab txav raws li qhov kev txiav txim ntawm lub teeb thiab kab xev, nws thiaj li ua pliag thiab txais los ntawm qhov chaw ib puag ncig. Yog hais tias qhov degradation tsis zoo yuav tsis txais los ntawm qhov chaw, ua rau "dawb qias tuaj."
Zaub mov ntim zaj duab xis kuaj xyuas qhov project yog muab faib rau cov pawg hauv qab no:
Cov tsos yuav tsum ua kom zoo, tsis khawb, kub hnyiab, npuas, roj hlav thiab pob txav, ua kom sov tho tawm, tsis muaj kev foob. Cov yeeb yaj kiab yuav tsum yog dawb ntawm cov kab nrawm, porosity thiab sib cais ntawm txheej txheej. Tsis muaj impurities, txawv teb chaws thiab roj thiab lwm yam pa phem.
Hnab soaking kua, yuav tsis hnov ntxhiab tsw, tsw, lim dej thiab decolorization phenomenon.
