Kubvisa furo rinogadzirwa panguva yekugadzira nekuputira.Zvinosvibisa zita remunhuimhando yechinhu chinoshandiswa kuderedza furo rinogadzirwa panguva yekugadzira uye/kana kushandisa machira. Saka chii chinokanganisa kubviswa kwemafuta mumachira?

1. Kusimba kwemusoro
Kusimba kwepamusoro kwependi ine simba guru pa defoamer. Kusimba kwepamusoro kwe defoamer kunofanira kunge kwakaderera pane kwependi, zvikasadaro haizokwanisi kubvisa furo nekudzivisa furo. Kusimba kwepamusoro kwependi chinhu chinoshanduka, saka pakusarudza defoamer, zvese kusimba kwepamusoro uye kusiyana kwesimba repamusoro kwesystem kunofanirwa kufungwa nezvazvo.

2. Zvimwe zvinowedzerwa
Mazhinji ma surfactants anoshandiswa mu coatings haashande nema defoamers. Kunyanya, emulsifiers, wetting and dispersing agents, leveling agents, thickeners, nezvimwewo zvinokanganisa mashandiro ema defoamers. Saka, pakubatanidza zvimwe zvinhu zvakasiyana-siyana, tinofanira kutarisisa hukama huripo pakati pezvimwe zvinhu zvakasiyana uye kusarudza nzvimbo yakanaka yekuenzanisa.

3. Zvinhu zvinorapa
Kana pendi ikapinda mukupisa kwakanyanya pakupisa kwemumba, viscosity inodonha ipapo ipapo uye mabubbles anogona kufamba pamusoro. Zvisinei, nekuda kwekushanduka kwe solvent, kupera kwependi, uye kuwedzera kwekusimba kwepamusoro, furo riri mupendi richagadzikana, nokudaro richivharirwa pamusoro, zvichikonzera maburi ekupwanyika uye maburi ekupinza. Nokudaro, tembiricha yekubika, kumhanya kwekupisa, chiyero chekudonha kwe solvent, nezvimwewo zvinokanganisawo defoaming effect.

4. Kusimba kwezvipfeko, viscosity, uye kusimba kwehunyoro
Mapendi matete akasimba, mapendi matete akasimba, uye mapendi matete akasimba zvese zvakaoma kubvisa furo. Pane zvinhu zvakawanda zvisingakodzeri kubvisa furo, zvakaita sekuoma kwemapendi matete kupararira mumapendi aya, kunonoka kwemapendi matete anoshanduka kuita mapendi matete, kuderera kwekukwanisa kwemapendi kufamba pamusoro, uye kusimba kwakanyanya kwemapendi matete. Furo riri mumapendi aya rakaoma kubvisa, uye zvakakosha kusarudza mapendi matete ne mapendi matete ekushandisa pamwe chete.

5. Nzira yekuputira uye tembiricha yekuvaka
Kune nzira dzakawanda dzekushandisa machira, dzinosanganisira kukwesha, kuputira machira, kudira, kukwesha, kupfapfaidza, kuprinda pachidzitiro, nezvimwewo. Kukwesha machira uchishandisa nzira dzakasiyana dzemachira kwakasiyanawo. Kukwesha nekuvhara machira zvinoburitsa furo rakawanda kupfuura kupfapfaidza nekukwesha. Pamusoro pezvo, nzvimbo yekuvaka ine tembiricha yakakwira inogadzira furo rakawanda kupfuura rine tembiricha yakaderera, asi furo iri nyorewo kubvisa kana tembiricha yakakwira.
