決定環(huán)氧地坪漆施工后質(zhì)量的因素有哪些?
環(huán)氧地坪漆涂裝的施工環(huán)境是指施工場地環(huán)境,包括地面含水量多少,空氣濕度,溫度等施工條件是否允許。施工環(huán)境在環(huán)氧地坪漆涂料的涂裝中,對于環(huán)氧涂料干燥時間與成膜的好壞起著重要的作用,對環(huán)氧地坪漆涂膜的黏度和環(huán)氧地坪漆涂層的質(zhì)量也有很大的影響。其次,光照也是影響地坪漆涂裝效果的重要因素之一,地坪漆涂料在貯存和運(yùn)輸過程中要防止暴曬,在施工過程中要防止陽光直射。尤其在炎熱高溫的夏季,陽光直射下的被涂飾的地坪漆基層表面溫度過高,會使其脫水或脫溶劑速度過快,使成膜的效果不佳,從而嚴(yán)重影響地坪漆涂層的質(zhì)量。甚至?xí)a(chǎn)生色差。
The construction environment of epoxy floor paint coating refers to the construction site environment, including the amount of ground water content, air humidity, temperature and other construction conditions are allowed. Construction environment plays an important role in the coating of epoxy floor paint, which has great influence on the drying time and film forming quality of epoxy floor paint, as well as the viscosity and quality of floor paint. Secondly, illumination is also one of the important factors affecting the painting effect of floor paint. Floor paint should be protected from sun exposure during storage and transportation, and direct sunlight should be prevented during construction. Especially in hot and high temperature summer, the surface temperature of the coated floor paint under direct sunlight is too high, which will make its dehydration or solvent removal speed too fast, so that the effect of film formation is not good, thus seriously affecting the quality of the floor paint coating. It even produces color aberration.
施工時要保證地坪漆施工現(xiàn)場的通風(fēng),但風(fēng)力又不能過大。這是因?yàn)轱L(fēng)力過大會分別加速地坪漆涂料 中溶劑和水分的蒸發(fā),使地坪漆涂料成膜不佳;此外還會降低空氣的潔凈度,使地坪漆涂膜沾上雜質(zhì),影響美觀。所以,當(dāng)風(fēng)力級別>4級的大風(fēng)天氣,應(yīng)適當(dāng)停止地坪漆涂料的施工。
During construction, the ventilation of floor paint construction site should be ensured, but the wind force should not be too large. This is because excessive wind speed up the evaporation of solvent and water in floor paint, which makes the film formation of floor paint poor. In addition, it will reduce the cleanliness of the air, make the floor paint film contaminated with impurities, and affect the beauty. Therefore, when the wind level is higher than 4, the application of floor paint should be stopped appropriately.
同時,也應(yīng)考慮污染物質(zhì)的影響。施工現(xiàn)場周圍環(huán)境中,如有工廠或汽車排出的大量的廢氣,如SO2,H2S等腐蝕性氣體,以及周 圍環(huán)境中產(chǎn)生飛揚(yáng)的灰塵,都將對涂料的施工質(zhì)量造成影響。因此當(dāng)發(fā)現(xiàn)施工現(xiàn)場有特殊的氣味或飛揚(yáng)的塵土,應(yīng)暫停施工,當(dāng)發(fā)現(xiàn)污染物質(zhì)已經(jīng)沽污部分涂層,應(yīng)及時清洗干凈。
At the same time, the influence of pollutants should also be considered. In the surrounding environment of the construction site, if there is a large amount of waste gas discharged from factories or automobiles, such as SO2, H2S and other corrosive gases, as well as flying dust in the surrounding environment, it will affect the construction quality of the paint. Therefore, when it is found that there is a special odor or flying dust in the construction site, construction should be suspended. When it is found that the contaminants have already polluted part of the coating, it should be cleaned in time.
綜上所述,為了確保環(huán)氧地坪漆涂裝施工質(zhì)量,延長環(huán)氧地坪漆使用壽命,在進(jìn)行室外施工時,最好選在晴天。當(dāng)施工現(xiàn)場周圍環(huán)境的溫度低于5℃、大雨、風(fēng)沙、濃霧等天氣應(yīng)當(dāng)避免施工。
To sum up, in order to ensure the quality of epoxy floor paint painting and prolong the service life of epoxy floor paint, it is better to choose sunny days for outdoor construction. Construction should be avoided when the ambient temperature of the construction site is below 5 C, heavy rain, wind and sand, thick fog and other weather conditions.
