彩鋼房材料油漆的效果主要有：緩蝕、陰極維護(hù)和屏蔽三種效果。
The paint effects of color steel room materials mainly include corrosion inhibition, cathode maintenance and shielding.
1、陰極維護(hù)的效果：使用鋅粉的陰極維護(hù)效果，制成的環(huán)氧富鋅漆和無(wú)機(jī)硅酸富鋅漆具有非常好的防銹效果，活動(dòng)板房是重防腐涂料系統(tǒng)中的底漆。高含量的鋅粉與輕鋼構(gòu)造嚴(yán)密觸摸，因?yàn)殇\的電位比輕鋼構(gòu)造低，腐蝕電流就會(huì)從鋅流向輕鋼構(gòu)造，鋅粉首要被腐蝕從而就維護(hù)了輕鋼構(gòu)造。鋅粉在大氣中的腐蝕產(chǎn)品尷尬溶堿式鹽，它們會(huì)填沒(méi)涂層中的空地，所以也具有維護(hù)效果。
1. Cathode maintenance effect: the cathode maintenance effect of zinc powder is used. The epoxy zinc rich paint and inorganic silicate zinc rich paint have very good rust prevention effect. The movable board room is the primer in the heavy-duty anti-corrosion coating system. The high content of zinc powder closely touches the light steel structure, because the potential of zinc is lower than that of light steel structure, the corrosion current will flow from zinc to light steel structure, and the zinc powder is mainly corroded, thus maintaining the light steel structure. The corrosive products of zinc powder in the atmosphere are soluble alkaline salts. They will fill the empty space in the coating, so they also have maintenance effect.
2、緩蝕的效果:油漆的防銹效果在較大程度上依托防銹顏料的緩蝕效果。以磷酸鋅為例，它具有構(gòu)成堿式絡(luò)合物的才能，活動(dòng)板房能夠與漆基的極性基團(tuán)進(jìn)一步絡(luò)合，生成安穩(wěn)的交聯(lián)絡(luò)合物，不只增強(qiáng)了漆膜的耐水性和附著力，一起在輕鋼構(gòu)造彩鋼板房資料外表構(gòu)成了結(jié)實(shí)的鐵-鋅-磷酸鹽絡(luò)合物，阻撓銹蝕的構(gòu)成和開(kāi)展，下降輕鋼構(gòu)造彩鋼板房的腐蝕速度。
2. Corrosion inhibition effect: the antirust effect of paint depends on the corrosion inhibition effect of antirust pigment to a large extent. Taking zinc phosphate as an example, it has the ability to form a basic complex. The movable plank house can further complex with the polar groups of the paint base to form a stable cross complex, which not only enhances the water resistance and adhesion of the paint film, but also forms a strong iron zinc phosphate complex on the surface of the color steel plank house constructed of light steel, which hinders the composition and development of corrosion and reduces the corrosion rate of the color steel plank house constructed of light steel.
3、屏蔽的效果：活動(dòng)房油漆通過(guò)杰出的施工，覆蓋在輕鋼構(gòu)造外表，能更好地阻隔輕鋼構(gòu)造與外界腐蝕環(huán)境的觸摸。也就是說(shuō)，油漆阻撓了大氣中的氧氣、水汽和其它腐蝕性離子對(duì)輕鋼構(gòu)造彩鋼板房資料的侵蝕。
3. Shielding effect: through excellent construction, the paint of the movable house covers the surface of the light steel structure, which can better block the touch of the light steel structure and the external corrosive environment. In other words, the paint hinders the erosion of oxygen, water vapor and other corrosive ions in the atmosphere to the data of color steel plank house with light steel structure.
