Oleic acids tsim ib chav kawm ntawm unsaturated fatty acids los yog lawv cov derivatives, cov neeg sawv cev tshaj plaws uas yog oleic acid (C₁₈H₃₄O₂).

Ib tug leaching tus neeg sawv cev yog ib yam tshuaj uas siv nyob rau hauv chemical los yog industrial processes kom yaj los yog rho tawm cov hom phiaj.

Hydroxamic acids yog ib chav kawm ntawm cov organic tebchaw uas muaj -C(=O)–N–OH ua haujlwm pab pawg, dav siv nyob rau hauv cov tshuaj thiab kev lag luam sectors.

Adjusters yog cov khoom siv ntxiv ua haujlwm los txhim kho kev ua haujlwm ntawm cov tshuaj lom neeg lossis cov khoom lag luam; lawv lub luag haujlwm tseem ceeb yog hloov kho lub...

Txoj kev siv ntau tshaj plaws rau ester ntau lawm yog cov tshuaj tiv thaiv esterification, nyob rau hauv uas carboxylic acid reacts nrog cawv nyob rau hauv lub xub ntiag ntawm a...

Esters tuaj yeem raug cais raws li cov kua qaub tshwj xeeb uas lawv tau muab los.

Tsav los ntawm kev loj hlob sai ntawm cov khoom noj, tshuaj pleev ib ce, cov khoom siv tu, thiab kev lag luam tshuaj, kev lag luam xav tau rau cov neeg ua haujlwm foaming tseem ...

Kev tswj xyuas zoo rau cov neeg ua npuas ncauj feem ntau suav nrog kev tshuaj xyuas cov khoom siv raw, kev saib xyuas cov txheej txheem tsim khoom, thiab kev sim cov khoom tiav.

Qhov ceev ntawm qhuav- hmoov foaming agents feem ntau yog tsawg, xws li kwv yees li 0.3 mus rau 0.6 g / cm³ nyob rau hauv ib tug xoob lub xeev; Thaum me ntsis compacted, qhov ce...

Cov neeg ua npuas ncauj yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo - qhov cua, thiab qhov chaw txias, kom deb ntawm tshav ntuj ncaj qha, qhov kub thiab txias.

Foaming agents ua haujlwm los ntawm kev txo qhov nro ntawm cov kua; surfactant molecules adsorb ntawm cov pa roj-kua interface, yog li ua kom yooj yim tsim cov npuas npuas hauv ...

Feem ntau, foaming agents tsim ib zaj duab xis molecular ntawm qhov sib cuam tshuam ntawm cov kua thiab gaseous theem, yog li ua rau npuas kom muaj nyob ruaj khov.
