聚氨酯环氧地坪漆塗裝粗糙的原因及解決方法

聚氨酯环氧地坪漆塗裝出現粗糙現象有以下幾個方面的原因：一、施工环境和环氧地坪漆漆膜幹燥過程中的环境不幹凈，灰塵多，使灰塵落在還處於流平階段的漆膜上，最終導致灰塵黏附於环氧地坪漆塗膜上而使塗膜出現粗糙現象。
The reasons for the roughness of polyurethane epoxy floor paint are as follows: 1. The construction environment and the drying process of the epoxy floor paint film are not clean and dusty, which makes the dust fall on the film which is still in the leveling stage, and eventually causes the dust to adhere to the floor paint film and makes the film rough.
二、环氧地坪漆塗料塗裝前沒有過濾，混入機械雜質，這些機械雜質與塗料一起被塗裝在瞭被塗物上，當塗膜幹燥後機械雜質就突顯在环氧地坪漆塗膜上瞭，最後導致塗膜出現瞭粗糙的現象。
2. The epoxy floor paint is not filtered before painting, and is mixed with mechanical impurities. These mechanical impurities are coated on the coatings together with the coatings. When the coatings are dried, the mechanical impur彩色沥清地坪ities are highlighted on the floor paint coatings, which eventually leads to the appearance of rough coatings.
三、由於聚氨酯环氧地坪漆塗料是雙組分或多組分塗料，又屬於化學固化型塗料，所以當塗料混入固化劑後，塗料就開始起化學作用，地坪漆塗料黏度就慢慢升高，到特定時間後就開始膠化，直接最後固化成膜。當塗料開始膠化仍繼續施工時，地坪漆塗膜就可能出現粗糙瞭。
3. Because the polyurethane epoxy floor paint is a two-component or multi-component coating, and belongs to chemical curing coating, when the paint is mixed with curing agent, the paint begins to play a chemical role, and the viscosity of the floor paint gradually increases, and begins to gelatinize after a specific time, and finally solidifies directly into a film. When the paint starts to gel and continues to be constructed, the paint film on floor paint may be rough.
四、施工現場溫度太高，稀釋劑揮發太快，环氧地坪漆塗料塗到被塗物上已經沒有流平的時間就已經開始固化，因此就會出現粗糙的現象。
Fourth, the construction site temperature is too high, the diluent volatilizes too fast, the epoxy floor paint coated on the coating has no leveling time has begun to solidify, so there will be rough phenomenon.
出現粗糙現象如何解決呢？
How to solve the problem of roughness?
做好施工現場和待幹現場的清潔工作，杜絕灰塵對环氧地坪漆漆膜的污染。塗料施工前，按產品說明書要求，調配好(按各組分的配比配好塗料，再用稀釋劑調整到適合施工的黏度)地坪漆塗料後，用120目紗佈把塗料過濾後再施工，即可避免由於機械雜質所引起的促擦現象瞭。
Do the cleaning work at the construction site and dry site, and eliminate the pollution of the dust on the epoxy floor paint film. Before coating construction, according to the requirements of product specifications, after mixing the floor paint (according to the proportion of each component, and then adjusting the diluent to the suitable construction viscosity), th环氧地坪e floor paint can be filtered with 120 mesh gauze and then constructed, which can avoid the friction-promoting phenomenon caused by mechanical impurities.
环氧地坪漆塗裝前，根據塗料的可施工時間計算好塗料的用量，再進行塗料配比和稀釋等後續工作，用多少配多少，不能多配。如發現有膠化的地坪漆塗料就不能再用。換用適合口徑的噴槍，調整好空氣壓力和適宜的噴塗距離等。換用慢幹的高沸點稀釋劑。
Before the epoxy floor paint is painted, the amount of the paint should be calculated according to the construction time of the paint, and then the following work such as the proportion and dilution of the paint should be carried out. If there is a gelatinized floor paint, it will not be used again. Replace the spray gun that fits the caliber, adjust the air pressure and the appropriate spraying distance. Replace the slow drying high boiling point diluent.
處理好下層，從底層開始就要按施工要求做好，中層要杜絕粗糙現象，面層施工前一定要把中層清理幹凈，確認無灰塵後再施工，這樣就可以解決环氧地坪漆該類的粗糙現象瞭。
To deal with the lower layer well, we should do a good job according to the construction requirements from the bottom layer. The middle layer should eliminate the rough phenomenon. Before the surface layer construction, we must clean the middle layer, confirm that there is no dust before construction, so that we can solve this kind of rough phenomena of epoxy floor paint.
