Ngenxa yesiqulatho esisezantsi se-VOC yeengubo ezisekelwe emanzini, ziya zithandwa ngakumbi phakathi kwabathengi.Nangona kunjalo, kwezinye iipeyinti ezisekelwe emanzini, siya kufumanisa ukuba ukuba asiphathwanga ngexesha, kulula ukuvelisa imingxuma ye-bubble kunye namehlo eentlanzi, kodwa ezinye aziyi.Yintoni imfihlelo embindini?Impendulo kunye okanye ngaphandle kokongeza i-coating defoamer esekelwe emanzini.

Ziziphi izongezo ezifakwe kwiingubo ezisekelwe emanzini
Iingubo ezisekelwe emanzini zenziwe ngokukodwa ngamanzi njenge-solvent, kwaye izongezelelo ezahlukeneyo ziya kongezwa kwinkqubo yokuqulunqwa, njengale: i-agent yokomisa, i-anti-mildew agent, i-fungicide, i-co-solvent, i-thickener, njl. ukusebenza kweengubo ezisekelwe emanzini.

Kutheni ipeyinti esekelwe emanzini iqhuma
Kwezi zihlomelo eziqulathwe ngasentla sinokubona ukuba uninzi lwezongezo eziqulethwe kwiingubo ezisekwe emanzini zezabantu abasebenzisa i-surfactants.

nto leyo enokubangela lula ukuveliswa kogwebu.Ngokukodwa kwinkqubo yokuxuba umatshini wokuvelisa i-coating, kulula ukuvelisa inani elikhulu le-foam, kwaye kunzima ukuphelisa.Umahluko phakathi kwesizathu sokuba ezinye zazo zibe namagwebu okanye kutheni ezinye zingaphumi ugwebu kulele ekubeni i-coating defoamer esekwe emanzini iyongezwa na.

I-defoamer esekelwe emanzini inokujolisa ingxaki ye-foam ye-coatings yamanzi, kukho umphumo omuhle wokutshatyalaliswa kwe-foam kunye ne-foam inhibition, ngenxa yengxaki ye-foam ye-coating, ungathethi ngayo.Ke ngoko, ezinye iingubo ezisekelwe emanzini azinagwebu ngenxa yokuba ziqulethe i-defoamer esekelwe emanzini.

Ukongeza i-defoamer yepeyinti esekelwe emanzini kwipeyinti esekwe emanzini ifaniswa nokunika umgangatho wepeyinti ibakala.Liqabane elilungileyo leengubo ezisekelwe emanzini.

Izinto eziluncedo kwi-coating defoamer esekelwe emanzini
I-defoamer yokugqoka esekelwe emanzini yenziwe nge-organic polyether ester njengenxalenye ephambili ngenkqubo ekhethekileyo.

Izinto ezilungileyo zibandakanya: i-emulsification elungileyo, i-dispersibility eqinile, ukukhupha amagwebu ngokukhawuleza kunye nokuthintela amagwebu.Kuba amanzi-based ukutyabeka ingxaki amagwebu, akayi kuba nefuthe elibi kwinkqubo, akukho lula ibleach oyile eyaphukileyo emulsion.Kulula kwaye kulula ukuyisebenzisa.Abavelisi bemithombo, ukusebenza kweendleko eziphezulu, ixabiso elinenzuzo ngakumbi.
