    揭示环氧地坪漆施工的环境要求标准

    涂装环境条件对环氧地坪涂装工程质量影响很大,主要体现在以下方面:涂料本身对涂装环境条件有要求,只有在符合该要求的环境下施工,才能达到好的效果,目前常用的环氧地坪漆涂装料对涂装环境的要求一般如下:无论封闭底漆、中涂漆、还是面漆,由于胺类固化剂反应一般低于5℃基本不反应,所以涂装环境温度在10℃以上时最佳,如低于这个温度,对涂料则需采取一些改进措施了,并在涂装时特别注意。在20℃以上时建议采用夏用型,20℃以下时,建议采用动用系型,装预固化过程中,基材表面温度应高于露点3℃以上, 以防基材及湿膜表面凝结水汽,影响涂层的辅助力合表面效果,检测环境温度的仪表有温度测量表,测量干湿浸泡温度的操纵干湿度,电子温度连续记录仪等,测量时,仪表应装于采集热、冷及平均数据的部位,但不得装于直射阳光。

    The environmental conditions have a great influence on the quality of the epoxy floor painting project, which is mainly reflected in the following aspects: the coating itself has requirements for the environmental conditions of the coating, and only in the environment that meets the requirements can good results be achieved. The requirements of the epoxy floor paint coating materials commonly used at present are generally as follows: no matter sealed. Closed primer, mid-coat or topcoat, because the reaction of amine curing agent is generally less than 5 C, it is best to coat at ambient temperature above 10 C. If it is lower than this temperature, some improvement measures should be taken for the coatings, and special attention should be paid to the coatings. Summer type is recommended when the temperature is above 20 C. When the temperature is below 20 C, it is suggested that the use system type be adopted. During the pre-curing process, the surface temperature of the base material should be higher than 3 C, in order to prevent the condensation of water vapor on the surface of the base material and wet film, which will affect the auxiliary force and surface effect of the coating. The instrument for measuring the ambient temperature has a temperature measuring meter and measuring the When measuring, the instrument should be installed in the place where the heat, cold and average data are collected, but not in direct sunlight. 高湿度也对涂层外观有很大影响,特别要避免在低温高湿环境下施工。所以一般相对湿度小于85%时方能施工,此类涂料一般可同时调整固化剂来适应不同的施工条件。

    High humidity also has a great impact on the appearance of the coating, especially to avoid construction in low temperature and high humidity environment. Therefore, the general relative humidity is less than 85% before construction, such coatings can generally adjust curing agent at the same time to adapt to different construction conditions.

    在基材表面温度不能满足高于涂装环境露点3度以上这一条件时,一方面基材表面结露(有一层水膜),造成表面缺陷。特别是面漆(包括溶剂型环氧及无溶剂环氧),易造成涂膜表面光泽低、发雾、发白、发粘、油点、硬度低等漆病,大大降低表面装饰效果,严重时造成返工。

    When the surface temperature of the substrate can not meet the condition that the dew point of the coating environment is higher than 3 degrees, on the one hand, the surface of the substrate dew (with a layer of water film), resulting in surface defects. Especially topcoats (including solvent-based epoxy and solvent-free epoxy) are liable to cause paint diseases such as low gloss, fogging, whitening, sticking, oil point and low hardness, which greatly reduce the decorative effect of the surface and cause rework in serious cases.

    另外,环氧地坪涂装要求洁净无尘的涂装环境,在养护期间要求环境密闭等,也对工程质量影响很大。这包括施工场所是否有扬尘,在施工场所是否会淋雨等。

    In addition, epoxy floor painting requires clean and dust-free painting environment, and requires environmental sealing during maintenance, which also has a great impact on the quality of the project. This includes whether there is dust in the construction site, whether there will be rain in the construction site and so on.
