上海環氧地坪漆涂裝粗糙的原因及解決方法
編輯:admin   文章來源:未知   時間:2018-08-09
 
上海環氧地坪漆涂裝出現粗糙現象有以下幾個方面的原因:
  一、施工環境和上海環氧地坪漆漆膜干燥過程中的環境不干凈,灰塵多,使灰塵落在還處于流平階段的漆膜上,最終導致灰塵黏附于地坪漆涂膜上而使涂膜出現粗糙現象。
  二、上海環氧地坪漆涂料涂裝前沒有過濾,混入機械雜質,這些機械雜質與涂料一起被涂裝在了被涂物上,當涂膜干燥后機械雜質就突顯在地坪漆涂膜上了,最后導致涂膜出現了粗糙的現象。
  三、由于聚氨酯環氧地坪漆涂料是雙組分或多組分涂料,又屬于化學固化型涂料,所以當涂料混入固化劑后,涂料就開始起化學作用,地坪漆涂料黏度就慢慢升高,到特定時間后就開始膠化,直接最后固化成膜。當涂料開始膠化仍繼續施工時,地坪漆涂膜就可能出現粗糙了。
  四、施工現場溫度太高,稀釋劑揮發太快,環氧地坪漆涂料涂到被涂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。
  出現粗糙現象如何解決呢?
  做好施工現場和待干現場的清潔工作,杜絕灰塵對環氧地坪漆漆膜的污染。涂料施工前,按產品說明書要求,調配好(按各組分的配比配好涂料,再用稀釋劑調整到適合施工的黏度)地坪漆涂料后,用120目紗布把涂料過濾后再施工,即可避免由于機械雜質所引起的促擦現象了。
  上海環氧地坪漆涂裝前,根據涂料的可施工時間計算好涂料的用量,再進行涂料配比和稀釋等后續工作,用多少配多少,不能多配。如發現有膠化的地坪漆涂料就不能再用。換用適合口徑的噴槍,調整好空氣壓力和適宜的噴涂距離等。換用慢干的高沸點稀釋劑。
  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干凈,確認無灰塵后再施工,這樣就可以解決環氧地坪漆該類的粗糙現象了
