*Zvinhu Zvigadzirwa:

1.Excellent Anti-corrosion performance, makemikari emhepo, munyu, peturu, parafini, mafuta emotokari, hydrocarbon solvents, humidity, mvura uye condensation;
2, yakanaka kuchinjika, kupfeka kuramba, kukanganisa kuramba.
3, Kuita kwakanaka kwekushongedza: kuchengetedza kwechiedza, kuchengetedza kwemavara kuita kwakanaka.
4, Kupisa kupikisa kusvika 120 ℃, kupikisa kwemamiriro ekunze kwakatanhamara, kugadzira kunowedzera kuchembera kwemaawa 1000;
5, Overcoating iri nyore kugadzirisa uye inogona kurapwa pakamuri tembiricha kana kuomeswa pane yakaderera tembiricha.

*Kushandiswa Kwechigadzirwa:

Inoshanda kune ndege, motokari, zvikepe, petroleum machines, engineering engineering, mabhiriji, magetsi emagetsi emagetsi, high-voltage switchgear uye mamwe makuru makuru esimbi zvivako, kuti zvibudirire kushongedza kwepamusoro uye kudzivirira.

*Kufananidza Paint:

Kutanga: Epoxy primer, epoxy zinc phosphate primer.
Inoshanda substrates: simbi, aruminiyamu, isiri-simbi zvinhu, nezvimwe.

*Surface Treatment:

Pamusoro peiyo primer inofanira kunge yakachena, yakaoma uye isina kusvibiswa.Ndapota teererai kupindirana kwekuvhara pakati pekuvaka uye primer.

*Construction Condition:

Iyo substrate tembiricha haina kudzika kupfuura 5 ℃, uye inokwana 3 ℃ yakakwirira kupfuura tembiricha yedova remhepo, uye hunyoro hwehukama huri <85% (tembiricha uye hunyoro hunofanirwa kuyerwa pedyo neiyo substrate).Kuvaka kunorambidzwa zvachose mumhute, mvura, sinou, uye nemhepo.

Pre-jasi pendi yekutanga uye yepakati pendi, woomesa chigadzirwa mushure memaawa makumi maviri nemana.Kupfapfaidza kunoshandiswa kupfapfaidza 1-2 nguva kuti uwane iyo yakatsanangurwa firimu ukobvu, uye yakakurudzirwa ukobvu i60 μm.Mushure mekuvaka, firimu repende rinofanira kunge rakatsetseka uye rakapfava, uye ruvara runofanira kunge ruchienderana, uye hapafanirwe kunge paine sagging, blistering, orenji peel uye zvimwe zvirwere zvependi.
