保定環(huán)氧地坪漆在涂裝中出現(xiàn)縮孔現(xiàn)象有施工方面的原因，也可能是涂料存在問題。如金屬底材除油、除銹不干凈，被涂物表面有油污或灰塵，就會(huì)導(dǎo)致漆膜縮孔。底涂層太光滑堅(jiān)硬（環(huán)氧底漆常有這種現(xiàn)象），不經(jīng)打磨處理，直接涂裝面漆，因各自表面張力不一致，就會(huì)產(chǎn)生縮孔，甚至魚眼。施工環(huán)境被硅油、油氣污染，也產(chǎn)生縮孔。涂料生產(chǎn)時(shí)用錯(cuò)含硅助劑或加量不恰當(dāng)，會(huì)引起涂膜縮孔，尤其是重涂時(shí)，很容易產(chǎn)生魚眼。
The shrinkage of epoxy floor paint in painting is due to construction reasons, and may also be a problem of the paint. If the metal substrate degreasing, rust removal is not clean, there is oil or dust on the surface of the coating, it will lead to shrinkage of the paint film. The primer is too smooth and hard (this phenomenon often occurs in epoxy primers). Without polishing, the primer is directly coated. Because of the different surface tension, shrinkage holes and even fish eyes will occur. The construction environment is polluted by silicone oil and oil and gas, and shrinkage is also produced. The inappropriate use of silicon-containing additives or additives in the production of coatings can cause shrinkage of coatings, especially in the case of re-coating, it is easy to produce fish eyes.
保定環(huán)氧地坪漆在涂裝時(shí)要防止這種現(xiàn)象，首先金屬表面處理要干凈，船舶維修要用高壓水沖洗干凈舊漆膜和污物，讓底材干透后才涂裝。不要在油氣在和灰塵大的環(huán)境中施工，制造涂料時(shí)，為了消泡和改善漆膜流干性，添加含硅消泡劑和流平劑時(shí)，要選用可重涂的助劑，并挖控制加入量。
Epoxy floor paint in painting to prevent this phenomenon, first of all, the metal surface treatment to be clean, ship maintenance to use high-pressure water to clean the old paint film and dirt, so that the base material is dry before painting. Do not use oil and gas in dusty environment. In order to defoam and improve the dryness of paint film, when adding silicon defoamer and leveling agent, we need to select reapplient additives and control the amount of additives.
