Idethi Yokuthunyelwa:21,Nov, 2022

Kwezinye izinqubo zokukhiqiza ukhonkolo, umakhi uvame ukwengeza i-ejenti ethile yokunciphisa amanzi, engagcina ukuwohloka kokhonkolo, ithuthukise ukuhlakazwa kwezinhlayiya zikakhonkolo, futhi inciphise ukusetshenziswa kwamanzi. Kodwa-ke, kune-drawback yokuthi i-ejenti yokunciphisa amanzi i-surfactant, okuzoholela esizukulwaneni se-foam, esizothinta amandla kanye nekhwalithi yekhonkrithi. Uma i-foam ikhiqizwa ngesikhathi sokwakhiwa, idinga ukususwa ngesikhathi. Kukhona i-defoamer engaba kakhulu Indlela engcono kakhulu yokuqeda igwebu likakhonkolo i-ejenti yokwehlisa usimende i-agent defoamer.

Ukusebenza kokwehlisa amagwebu kwe-ejenti yokunciphisa amanzi usimende:

Ii-defoamer ngokuyinhloko yenziwe nge-polyether eguquliwe futhi ingeye-polyetheri-defoamer. Ii-defoamer ngeke kuthinte kabi izakhiwo ezibalulekile zekhonkrithi ekusetshenzisweni kwegwebu lekhonkrithi, futhi ingaba nemiphumela eqinile yokukhipha amagwebu kanye ne-foam. Ii-defoamerine-dispersibility enhle kugwebu likakhonkolo, futhi ingahlakazwa ngokushesha egwebu likakhonkolo ukuze kuzuzwe umphumela wokugcina wokuphuka kwegwebu kanye nokukhipha amagwebu. Ngaphezu kokukhipha amagwebu kanye nokunqanda ukukhihliza amagwebu kugwebu likakhonkolo, lingaphinda likhiphe igwebu kumazinga okushisa aphezulu kanye nemvelo ye-asidi eqinile ne-alkali.

Umthelela wokuqeda amagwebu we-ejenti yokunciphisa amanzi usimendei-defoamer:

Umthelela wei-defoamer ekusebenzeni kokhonkolo kubonakaliswa ikakhulukazi ezicini ezimbili: ngakolunye uhlangothi, kungaqeda amabhamuza omoya phakathi kukakhonkolo kanye nefomula ngokwezinga elithile, kuvimbele ngempumelelo noma kuqede ukukhiqizwa kwekhekheba lezinyosi kanye nezindawo ezimakiwe endaweni ekhonkolo, futhi wenze ubuso bukakhonkolo bube ne-flatness ephezulu kanye ne-gloss. Ngakolunye uhlangothi, i-i-defoamer ingaqeda inani elikhulu lamabhamuza omoya kukhonkolo, inciphise okuqukethwe komoya kanye ne-porosity yangaphakathi yekhonkrithi, futhi ithuthukise izakhiwo zemishini nokuqina kokhonkolo.

Indlela yokusebenzisa i-ejenti yokunciphisa amanzi usimendei-defoamer:

1. Lapho ii-defoamer isetshenziselwa ukukhiqizwa kwegwebu elikhonkolo nge-ejenti yokunciphisa amanzi, i-slurry ye-foam yekhonkrithi izobe inamathele. Kunconywa ukwengeza i-i-defoamer ngokushesha lapho i-foam ikhiqizwa, engakwazi ukuqeda ngokushesha ama-bubbles amakhulu angalingani ku-foam yekhonkrithi futhi yethule umfaniswano Ama-bubbles amancane omoya angandisa ubulukhuni bekhonkrithi.

2. Ii-defoamer ine-dispersibility eqinile futhi kulula ukuyihlukanisa ngemva kokubekwa isikhathi eside. Kunconywa ukuthi ukuxuba okuqhubekayo kwenziwe ngesikhathi sokususwa kwegwebu lekhonkrithi.

3. Ii-defoamer ingehliswa ngenxa ye-alkalinity yayo, ngakho-ke sicela ugweme ukuyisebenzisa lapho inani le-pH lingaphezu kuka-10.
