Coloured natural iron oxides are earth pigments having outstanding characteristic, such as their stability under practically all conditions encountered in commercial applications. These pigments are unaffected chemically or physically by acids, alkalis, sunlight or moisture. They possess excellent hiding power, light fastness, reasonable tinting strength. They do not bleed or fade, are easily wetted and dispersed (Rammelt and Reinhardt, 1994; Morgan, 1990;Patton, 1973), opaque to UV light which provides good protection of paint binders (Rammelt and Reinhardt, 1994; Morgan, 1990), and can provide hard impervious films that resist outdoor weathering and superior protection at a relatively low cost. Protection mechanism of iron oxides to metal substrates is physical rather than chemical, i.e. by mechanically strengthening the paint film, reducing moisture permeation through the film, and by screening out destructive UV radiation (Payne, 1973). Alumina has no role in preventing steel from corrosion, but they possess the flaky structure that may help in corrosion prevention when assisted by another anticorrosive pigment (Svoboda and Mleziva, 1984). Combining these two pigments and calcining them together, a new pigment having different properties than that of its counterparts could be formed. 1.1.png 1.2.png |

| 著色天然氧化鐵是無機(jī)顏料,具有突出的特性，比如，在工業(yè)應(yīng)用所能遇到的幾乎任何條件下的穩(wěn)定性。這種顏料不受酸、堿、陽光或濕氣等化學(xué)上或物理上的影響。它們具有極好的覆蓋力、耐光性和適當(dāng)?shù)闹ΑＫ鼈儾粫?huì)褪色或脫色,且易于潤濕和分散( Rammelt和Reinhardt, 1994年；Morgan, 1990年;Patton, 1973年),不透紫外線，這就對(duì)漆粘合劑提供了良好保護(hù)( Rammelt和Reinhardt, 1994年；Morgan, 1990年)并且能夠提供硬物不易損壞的薄膜，以相對(duì)低的成本抵抗戶外天氣和提供優(yōu)良的保護(hù)。 鐵氧化物對(duì)底物的保護(hù)機(jī)制是物理上的，而不是化學(xué)上的，那就是說通過物理上地增強(qiáng)涂膜,減少濕氣穿透涂膜并屏蔽有害的紫外射線（Payne,1973年）。氧化鋁對(duì)鋼材沒有防腐作用,但是它們的鱗片狀構(gòu)造在有另一種防腐蝕顏料的輔助時(shí)有助于防腐（Svoboda和Mleziva,1984年）。組合這兩種顏料并一起焙燒,形成一種不同于其相應(yīng)物性能的新型顏料。 |
