Pendi yeAlkyd inodzivirira ngura inogona kushandiswa pamhando dzese dzesimbi, mapaipi, michina, simbi, nezvimwewo. Inokurumidza kuoma kana tembiricha yemumba, inodzivirira mvura zvakanaka, inoshanda zvakanyanya inodzivirira ngura uye inonamatira zvakanaka. Fomura iyi inonyanya kuumbwa nealkyd resin, anti-ngura pigments, extender pigments, driers, organic solvents, diluents, nezvimwewo, uye yakakamurwa kuita mhando mbiri: iron red alkyd anti-ngura pendi uye red tan alkyd anti-ngura pendi. Iron red alkyd anti-ngura pendi ialkyd resin inowedzerwa ne iron oxide red uye anti-ngura pigment fillers. Mushure mekukuya, wedzera huwandu hwakakodzera. Yakagadzirwa kubva kuorganic solvents. Yakakodzera anti-ngura primer pamusoro pesimbi. Fomura yered lead alkyd anti-ngura pendi inoumbwa nealkyd resin uye red lead anti-ngura pigment. Mushure mekukuya, organic solvents nezvimwe zvinowedzera zvinowedzerwa. Anti-ngura coating yesimbi structure surfaces.
1. Inogona kugadzirwa nekupfapfaidza nemhepo kana kukwesha.
2. Substrate inofanira kucheneswa isati yashandiswa uye isina guruva, ngura, uye mavara asati yashandiswa.
3. Musanganiswa unogona kushandiswa kugadzirisa viscosity.
4. Pakupfapfaidza topcoat, kana ganda rakapenya zvakanyanya, mirira kusvika pendi yekare yaoma kana kuiisa mujecha zvakaenzana usati waiisa.
5. Pakusarudza pfuti yekupfapfaidza pendi, chengeta chinhambwe che20 cm kubva pamusoro pesimbi. Caliber yepfuti yekupfapfaidza inofanira kugadziriswa uye kumhanya kwekupfapfaidza kunofanira kunge kwakafanana. Sarudza bhurashi rekuisa. Wedzera alkyd thinner kune alkyd anti-ngura pendi wosanganisa zvakanaka. Sarudza pendi yemhando yepamusoro. Bhurashi, bhurashi rakapfava uye rakaoma zvine mwero, uye simba rinofanira kunge rakafanana kana uchiisa pamusoro pechinhu chacho. Mushure mekunge pendi yekutanga yapera, zvinotora maminetsi angangoita makumi matatu kupfapfaidza pendi yechipiri. Kupfapfaidza pendi yechipiri kunogona kuwedzera ukobvu hwependi uye kunatsiridza mhedzisiro yekurwisa ngura.
