Ungakhetha kanjani i-Defoaming Agent?

Amabhamuza noma igwebu kwenzeka lapho igesi yethulwa futhi ivaleleke esixazululweni kanye ne-surfactant. Lawa mabhamuza angaba amabhamuza amakhulu noma amabhamuza ebusweni besixazululo, noma angaba amabhamuza amancane asatshalaliswa esixazululweni. Lawa magwebu angase abangele inkinga emikhiqizweni nasezinsizeni (njengokuchitheka kwempahla eluhlaza kuholela ekuncishisweni komthamo wokukhiqiza, ukulimala komshini, noma ukuwohloka kwekhwalithi yomkhiqizo, njll.).

Ama-Defoaming agentsziyisihluthulelo sokuvimbela nokulawula igwebu. Inganciphisa kakhulu noma ivimbele ukwakheka kwamabhamuza. Ezimweni ezisekelwe emanzini, umkhiqizo olungile we-antifoam unganciphisa noma uqede izinkinga ezihlobene negwebu.

Izinkinga ezilandelayo kufanele zicatshangelwe lapho ukhetha i-defoamer:

1. Nquma uhlelo lokusebenza oluthile oludinga ukukhishwa amagwebu. Izimo ezihlukene zohlelo lokusebenza zingadinga izinhlobo ezahlukene zama-ejenti akhipha amagwebu. Izicelo ezivamile zihlanganisa izinqubo zezimboni (ezifana nokucubungula ukudla, ukuhlanzwa kwamanzi angcolile kanye nokukhiqizwa kwamakhemikhali), imikhiqizo yabathengi (njengamapende, okokugcotshwa nezihlanzi) kanye nemithi.

2. Ukungezwani okungaphezulu kwe-ejenti yokukhipha amagwebu kufanele kube ngaphansi kunokucindezeleka okungaphezulu kwesisombululo esinamagwebu.

3. Qinisekisa ukuhambisana nesixazululo.

4. I-defoamer ekhethiwe kufanele ikwazi ukungena kungqimba oluncane lwegwebu futhi isakaze ngokuphumelelayo ku-interface ye-liquid/gas.

5. Ayincibilikisiwe endaweni enegwebu.

6. I-solubility ye-ejenti yokukhipha amagwebu esixazululweni esinamagwebu kufanele ibe phansi futhi akumele isabele ngesisombululo esinamagwebu.

7. Buyekeza ishidi ledatha lobuchwepheshe lomkhiqizi, ishidi ledatha yokuphepha, nezincwadi zomkhiqizo ukuze ufunde mayelana nezakhiwo, imiyalelo yokusebenza, nezinyathelo zokuphepha ezihambisana ne-defoamer ngayinye.

Lapho ukhetha i-defoamer, kungcono ukwenza ukuhlolwa kokuhlola ukuze uqinisekise ukusebenza kwayo ngaphansi kwezimo ezithile ngaphambi kokwenza ukukhetha kokugcina. Ngesikhathi esifanayo, ungathintana nochwepheshe noma abahlinzeki embonini ukuze uthole iziphakamiso nolwazi oluthe xaxa.
