Ngenxa yomxholo ophantsi we-VOC wezinto zokugquma ezisekelwe emanzini, ziya zithandwa ngakumbi ngabathengi. Nangona kunjalo, kwezinye iipeyinti ezisekelwe emanzini, siya kufumanisa ukuba ukuba azilungiswanga ngexesha, kulula ukuvelisa imingxunya yamaqamza kunye namehlo eentlanzi, kodwa ezinye aziyi kulungiswa. Yintoni imfihlakalo ephakathi? Impendulo kukuba xa wongeza okanye ungafaki i-defoamer yokugquma esekwe emanzini.

Zeziphi izongezo eziqukiweyo kwiingubo ezisekelwe emanzini
Iingubo ezisekelwe emanzini zenziwe ngamanzi njengesinyibilikisi, kwaye izongezo ezahlukeneyo ziya kongezwa kwinkqubo yokwenza, ezinje: iarhente yokomisa, iarhente yokulwa nokungunda, i-fungicide, i-co-solvent, i-thickener, njl.njl., ukomeleza ukusebenza kweengubo ezisekelwe emanzini.

Kutheni ipeyinti esekwe emanzini ivutha amadyungudyungu
Kwii-additives ezikhankanyiweyo apha ngasentla singabona ukuba uninzi lwezongezo ezikwi-water-based coating zeze-surfactants

nto leyo enokubangela ukuveliswa kwefoam ngokulula. Ingakumbi kwinkqubo yokuxuba umatshini wokuvelisa i-coating, kulula ukuvelisa i-foam eninzi, kwaye kunzima ukuyisusa. Umahluko phakathi kwesizathu sokuba ezinye zazo ziphume i-foam okanye isizathu sokuba ezinye zingaphumi i-foam uxhomekeke ekubeni i-defoamer esekwe emanzini yongezwa na okanye hayi.

I-defoamer esekwe emanzini inokujongana nengxaki ye-foam yeengubo ezisekwe emanzini, kukho isiphumo esihle sokucocwa kwe-foam kunye nokuthintela i-foam, kwingxaki ye-foam yengubo, musa ukuthetha ngayo. Ke ngoko, ezinye iingubo ezisekwe emanzini azifomi kuba ziqulethe i-defoamer esekwe emanzini.

Ukongeza i-defoamer yepeyinti esekwe emanzini kwipeyinti esekwe emanzini kufana nokunika umgangatho wepeyinti umgangatho ophezulu. Liqabane elifanelekileyo kwiingubo ezisekwe emanzini.

Iingenelo ze-defoamer yokugquma esekwe emanzini
I-defoamer yokugquma esekwe emanzini yenziwe nge-ester ye-polyether yendalo njengeyona nto iphambili ngenkqubo ekhethekileyo.

Iingenelo ziquka: i-emulsification elungileyo, ukusasazeka ngamandla, ukucoca ngokukhawuleza kunye nokuthintela i-foam. Kwingxaki ye-foam yokugquma esekwe emanzini, ayizukuba nefuthe elibi kwinkqubo, ayizukuba lula ukuyixuba i-oyile ephukileyo. Kulula ukuyisebenzisa kwaye kulula. Abavelisi bomthombo, ukusebenza okubiza kakhulu, ixabiso elingcono.
