Ukugutyula i-foam kukukwazi kwe-coating ukususa i-foam eveliswa ngexesha lenkqubo yemveliso kunye ne-coating.Izihlazoluhlobo lwesongezo esisetyenziselwa ukunciphisa igwebu eliveliswayo ngexesha lokwenziwa kunye/okanye ukusetyenziswa kweengubo. Ngoko ke zeziphi izinto ezichaphazela ukucocwa kweengubo?

1. Uxinzelelo lomphezulu
Uxinzelelo lomphezulu wengubo lunempembelelo enkulu kwi-defoamer. Uxinzelelo lomphezulu wengubo kufuneka lube ngaphantsi kunolo lwengubo, kungenjalo aluyi kukwazi ukususa i-foam nokuthintela i-foam. Uxinzelelo lomphezulu wengubo luyinto eguquguqukayo, ngoko ke xa ukhetha i-defoamer, kufuneka kuqwalaselwe uxinzelelo lomphezulu oluqhubekayo kunye notshintsho lomphezulu wenkqubo.

2. Ezinye izongezo
Uninzi lwe-surfactants ezisetyenziswa kwiingubo azihambelani ngokusebenzayo nee-defoamers. Ngokukodwa, ii-emulsifiers, ii-wetting kunye nee-dispersing agents, ii-leveling agents, ii-thickeners, njl.njl. ziya kuchaphazela impembelelo yee-defoamers. Ke ngoko, xa sidibanisa izongezo ezahlukeneyo, kufuneka siqwalasele ubudlelwane phakathi kwezongezo ezahlukeneyo kwaye sikhethe inqanaba elifanelekileyo lokulinganisela.

3. Izinto eziphilisayo
Xa ipeyinti ingena ekubhakeni okushushu kakhulu kubushushu begumbi, i-viscosity iya kwehla ngoko nangoko kwaye amaqamza anokuhamba aye kumphezulu. Nangona kunjalo, ngenxa yokuguquguquka kwe-solvent, ukuphiliswa kwepeyinti, kunye nokwanda kwe-viscosity yomphezulu, i-foam kwipeyinti iya kuzinza ngakumbi, ngaloo ndlela ibambeke kumphezulu, nto leyo ebangela ukuncitshiswa kwemingxuma kunye nemingxuma ye-pin. Ke ngoko, ubushushu bokubhaka, isantya sokupholisa, izinga lokuguquguquka kwe-solvent, njl.njl. nazo zichaphazela isiphumo sokucocwa kwe-defoaming.

4. Umxholo oqinileyo, ukutyeba, kunye nokuqina kweengubo
Iingubo eziqinileyo neziqinileyo, iingubo ezixineneyo nezinobungqindilili, kunye neengubo ezixineneyo nezinobungqindilili, zonke ezi zinto zinzima kakhulu ukuzisusa. Kukho izinto ezininzi ezinokubangela ukuba ii-defoam zisasazeke, njengobunzima bee-defoamers ukuba zisasazeke kwezi ngubo, isantya esicothayo see-microbubbles eziguquka zibe zii-macrobubbles, amandla anciphileyo okufuduka kwee-foams ziye kumphezulu, kunye ne-viscoelasticity ephezulu yee-foams. I-foam kwezi ngubo kunzima ukuyisusa, kwaye kuyimfuneko ukukhetha ii-defoamers kunye nee-deaerators ukuze zisetyenziswe kunye.

5. Indlela yokugquma kunye nobushushu bokwakha
Kukho iindlela ezininzi zokufaka i-coating, kuquka ukubrasha, i-roller coating, ukugalela, ukukrwela, ukutshiza, ukuprinta isikrini, njl. Umgangatho we-foam we-coating usebenzisa iindlela ezahlukeneyo zokugquma nawo wahlukile. I-brush kunye ne-roller coating zivelisa i-foam engaphezulu kune-spray kunye ne-scrap. Ukongeza, indawo yokwakha enobushushu obuphezulu ivelisa i-foam engaphezulu kune-froming ephantsi, kodwa i-foam kulula ukuyisusa xa ubushushu buphezulu.
