Ungayikhetha njani i-Agent ye-Defoaming?

I-Bubbles okanye i-foam iyenzeka xa igesi isungulwa kwaye ibanjwe kwisisombululo kunye ne-surfactant. La maqamza anokuba ngamaqamza amakhulu okanye amaqamza kumphezulu wesisombululo, okanye abe ngamaqamza amancinci asasazwe kwisisombululo. La magwebu anokubangela ingxaki kwiimveliso kunye nezixhobo (ezifana nokuchitheka kwezinto ezikrwada kukhokelela ekuncitshisweni komthamo wemveliso, ukonakala komatshini, okanye ukuwohloka komgangatho wemveliso, njl. njl.).

Iiarhente zokuthoba amagwebuzingundoqo ekuthinteleni nasekulawuleni amagwebu. Inokunciphisa kakhulu okanye inqanda ukubunjwa kwamaqamza. Kwiindawo ezisekelwe emanzini, imveliso ye-antifoam efanelekileyo inokunciphisa okanye isuse iingxaki ezinxulumene ne-foam.

Le miba ilandelayo kufuneka iqwalaselwe xa ukhetha i-defoamer:

1. Qinisekisa usetyenziso oluthile olufuna ukuthululwa kogwebu. Iimeko ezahlukeneyo zesicelo zinokufuna iintlobo ezahlukeneyo zeearhente zokuthoba ugwebu. Ukusetyenziswa okuqhelekileyo kubandakanya iinkqubo zoshishino (ezifana nokulungiswa kokutya, ukucocwa kwamanzi amdaka kunye nokuveliswa kweekhemikhali), iimveliso zabathengi (ezifana neepeyinti, iingubo kunye nezicoci) kunye namayeza.

2. Ukunyanzeliswa komphezulu we-agent ye-defoaming kufuneka kube ngaphantsi koxinzelelo lomphezulu wesisombululo sogwebu.

3. Qinisekisa ukuhambelana nesisombululo.

4. I-defoamer ekhethiweyo kufuneka ikwazi ukungena kwindawo encinci ye-foam kwaye isasazeke ngokufanelekileyo kwi-liquid / gas interface.

5. Ayinyibilikiswa kwindawo enogwebu.

6. I-solubility ye-agent ye-defoaming kwisisombululo se-foaming kufuneka ibe phantsi kwaye akufanele iphendule ngesisombululo se-foaming.

7. Phonononga uxwebhu lwedatha yobugcisa bomenzi, ishidi ledatha yokhuseleko, kunye noncwadi lwemveliso ukuze ufunde malunga neempawu, imiyalelo yokusebenza, kunye nezilumkiso zokhuseleko ezinxulumene ne-defoamer nganye.

Xa ukhetha i-defoamer, kungcono ukuqhuba uvavanyo lokuvavanya ukuqinisekisa ukusebenza kwayo phantsi kweemeko ezithile ngaphambi kokuba wenze ukhetho lokugqibela. Kwangaxeshanye, unokubonisana neengcali okanye ababoneleli kwishishini ukufumana iingcebiso ezininzi kunye nolwazi.
