    技工介绍说环氧地坪表面发白的原因

    涂装的专注施工员工先容说环氧地坪口头发白的起因首要有下面几个方面的起因:环氧地坪漆发白特征挥发性涂料的涂层在干枯过程中,发生雾状模糊不清,并失却腻滑的征象.发生起因涂饰施工境遇湿度过穷,氛围中的水份直接进人涂层;或当氛围温度较低,湿度较穷,涂层中的溶剂挥发速率很快引起涂层口头温度急剧降落,较易使氛围中的湿气在涂层口头凝聚成水份浸入涂层中,结局引起雾状发白,并将此种发白称为"漫湿性发白".

    The main causes of oral whitening of epoxy flooring paint are as follows: foggy blurring and greasy and slippery appearance occurs in the coating of volatile epoxy flooring paint during drying up. The reason is that the humidity of the coating construction is too poor and the moisture in the atmosphere enters directly into the coating; or when the atmosphere temperature is low and the humidity is poor, the coating is coated. The volatilization rate of solvents in the coating quickly causes the oral temperature of the coating to drop sharply. It is easier for the moisture in the atmosphere to coagulate orally into water and immerse in the coating. The result is foggy whitening, which is called "diffuse whitening". 如硝基和虫胶涂料的涂层较易引起这样发白.再就是鉴于涂料中的真溶剂挥发比其稀释剂快得过量,结局引起涂层中部门树脂析出成白色积淀,使涂层发白,并将这样发白称为"树脂性发白".

    For example, the coating of nitro and shellac coatings is easy to cause such whitening. Moreover, in view of the fact that the volatilization of real solvents in coatings is faster than its diluent, the final result causes the white deposition of resin in the middle part of the coatings, whitening the coatings, which is called "resinous whitening".

    环氧地坪漆预防措施应抬高涂饰施工境遇的温度减削氛围的湿度;在涂料中要适合增补真溶剂以及稀释剂的沸点,并使涂料中的真溶剂沸点稍穷于或相等其稀释剂的沸点.修理步骤立刻适合提升涂层干枯温度,若前提首肯较佳采得红外线辐射器干枯涂层,使潮气从涂层中挥发遗失;在涂层发白处慢慢刷涂一层薄薄的该涂料的真溶剂,使涂层中析出的树脂从头熔解成连绵的涂层,或使涂层中的水气

    Preventive measures for epoxy floor paint should raise the temperature of coating construction and reduce the humidity of the atmosphere; it should be suitable for adding true solvents and the boiling point of diluents in coatings, and make the boiling point of true solvents in coatings a little less than or equal to the boiling point of their diluents. Repair steps should immediately be suitable for raising the drying temperature of coatings, if the premise is to obtain better infrared radiator drying coating, so that moisture from the coatings. Loss of volatility; slowly brush a thin layer of true solvent on the whitening part of the coating to melt the resin precipitated from the coating into a continuous coating from scratch, or to make the water vapor in the coating.

    无拘无束的挥发出走.关于虫胶清漆发白,还可用棉纱蘸得少数松节油揩擦发白处,水气立刻从涂层中挥发遗失.

    Unconstrained evaporation. For shellac varnish whitening, cotton yarn can also be dipped in a small amount of turpentine to wipe the whitening area, water vapor immediately volatilized from the coating lost.

    口头粗糙特征涂膜口头上有百般粒子而显得粗糙.发生起因涂料中有杂质;涂饰用具不清洁;施工境遇尘埃较多.预防措施须用200目网或布匹过滤涂料;涂饰用具要用溶剂洗涤清洁;施工境遇要透顶打扫,争得氛围中无尘埃沉降.修理步骤待涂层干结成硬膜后,用砂纸砂磨腻滑,再从头涂饰.

    Oral roughness is characterized by a wide variety of particles on the coating verbally, resulting in impurities in the coating; unclean appliances; more dust in the construction situation. Preventive measures should be 200 mesh mesh or cloth to filter the coating; coating appliances should be washed and cleaned by solvent; construction situation should be thoroughly cleaned to ensure dust-free deposition in the atmosphere. Repair steps should be done after the coating is dry-bound into a hard film, sandpaper sanded and slippery. Paint again from scratch.
