    1、涂料对基材的要求:
    1, the coating to the base material requirements:
    要使济南自流平涂料有很好的表面装饰效果,对基层要有较好的处理和养护。基层必须坚实牢固、耐水、无油污、无浮尘。新制的水泥基材碱性较强,漆膜遇水会后很容易返碱,为防止施工后返碱现象的发生,涂料施工时墙面pH值必须小于 10,同时基材必须干燥,含水率应小于 10%,若施工油性涂料则含水率必须小于 8%.
    To make jinan self-leveling coatings have good surface decorative effect, to better treatment and maintenance at the base. Must be strong enough at the grass-roots level, water resistant, no grease, no dust. New system of cement base material, strong alkaline film FanJian easily after the meeting, under the influence of water to prevent FanJian after construction, the phenomena of paint when construction metope pH value must be less than 10, and substrate must be dry, the moisture content should be less than 10%, if the construction is oily coating moisture content must be less than 8%.
    2、涂料对施工环境的要求:
    2, coating requirements of the construction environment:
    首先是环境温度,水性涂料一般要求在 5℃以上施工,环氧地坪涂料一般在10℃以上施工;其次是相对湿度,一般环境相对湿度小于 70%时,可以进行涂料施工。另外,在
    First of all is the environment temperature, the coating of ability in general requirements in construction for more than 5 ℃, epoxy floor coating is in commonly 10 ℃ above construction; Followed by the relative humidity, general environment relative humidity is less than 70%, the coating construction. In addition, in
    大风、雨、雪和过于干燥的天气条件下,不能施工。
    Wind, rain, snow and too dry weather conditions, not construction.
    3、影响涂料涂刷面积的因素:
    3, the factors influencing coatings area:
    影响济南自流平涂料涂刷面积的因素有很多,如基层的平整度、施工工具、涂料的质量等均影响到涂料的涂刷面积。基层越平整涂料施工时损耗越少,涂刷面积越大。涂刷面积也与施工工具有很大的联系,一般情况下喷涂施工损耗少,其次是刷涂,由于滚涂时有飞溅现象,因此是耗料的一种施工方式。涂料的遮盖力越强,涂刷面积越大。
    Influence factors of self-leveling coatings area of jinan has a lot of, such as grass-roots flatness, construction tools, such as the quality of the coating are affect the paint coating area. The less more smooth coating construction loss at the grass-roots level, besmear brushs the bigger area. Besmear to brush the area and construction tools also have a lot of links, typically spraying construction loss minimum, followed by brush, because you have splash phenomenon of roller coating, so it is one of the most consumption of material construction. The stronger the paint covering power, besmear brushs the bigger area.
    4、涂层厚度与产品质量的关系:
    4, the relationship between coating thickness and the quality of the product:
    济南自流平 http://www.jndmzp.com/  涂料施工过厚或过薄对漆膜质量都有影响,施工时一次涂膜过厚容易引起开裂、桔皮等现象,如果漆膜过薄则易出现产品不遮底、丰满度差,易褪色等现象。一般来说,涂料的湿膜厚度保持约 200微米、干膜厚度约 65微米即为标准漆膜厚度,施工时可分 2~3次涂刷,折算成涂刷面积大约为 5平方米/公升(注:基材表面平整,平涂工艺)。对深色漆来说,适当增加漆膜厚度有利于提高涂料的保色性
    Jinan construction too thick or too thin self-leveling coatings have impact on quality of paint film, a coating during the construction of a thick easy to cause cracking, the phenomenon such as orange peel, if paint film is easy to appear products do not cover the bottom is too thin, poor fullness, the phenomenon such as easy to fade. Generally speaking, the wet film thickness of paint to keep about 200 microns, the dry film thickness of about 65 microns for standard film thickness, namely construction can be divided into 2 ~ 3 times when brushing, convert besmear brushs area of about 5 square meters/liter (note: base material surface level off, smooth coating process). For brunet paint, proper increase of film thickness to improve coating color retention
