    打造高质量环氧地坪基面处理是关键

    2019-02-06 22:26:53 无锡盛发地坪科技有限公司 阅读

    如果不进行基面处理,则会对环氧地坪地面造成下列影响:1、粉尘严重,素地表面上有很多砂粒砂石素地出现粉尘,并且砂粒砂石严重则代表素地不够坚实,强度没有达到环氧地坪漆施工的最低标准C25以上,在过于疏松的素地上进行环氧地坪施工,则影响着环氧地坪漆与基面的粘接力,而且砂粒砂石也会阻碍环氧地坪地面的平整度,容易导致地平地面出现脱层等问题,所以在环氧地坪施工前必须将素地疏松的混凝土层去除。

    If the base surface is not treated, the following impacts will be caused on the epoxy floor: 1. The dust is serious, there are many sand gravel plain ground on the plain surface, and the gravel gravel represents that the plain ground is not solid enough, the strength is not up to the lowest standard C25 of the epoxy floor paint construction, and the construction of the epoxy floor paint on the loose plain ground will affect the floor paint. Adhesion with the base, and sand and gravel will also hinder the evenness of the floor, easily lead to delamination of the floor, so the loose concrete layer must be removed before the construction of epoxy floor. 2、坑洼较多,并且每个坑洼坑空的深浅不一而素地出现深浅大小不一的坑洼坑洞,则需要对其进行清除并且填充弥补,否则容易在地坪施工完成后,坑洞的地方则变成了空鼓的地方,当在进行高强冲击力的作业时,就容易使得地坪出现断裂等情况。

    2. There are many pits and holes with different depths and sizes, which need to be cleared and filled. Otherwise, after the construction of the floor, the place of the pit will become empty and bulging. When the high-impact operation is carried out, the floor will easily break.

    3、地面容易打滑,存在油污的残留素地存在油污污染是最常见的情况,而该情况是影响地坪涂料粘接力最大的因素。地坪漆存在渗透能力,涂料则可通过素地微小的细孔渗入,使得素地与地坪涂料两者的粘接技能提升。然而油污的存在则封闭了微小细孔的空间,使得地坪涂料不能与素地进行良好的粘接,存在油污污染的区域则容易脱落。

    3. The ground is easy to slip. Oil pollution is the most common condition in the plain land with oil pollution, which is the most important factor affecting the adhesion of floor coatings. Floor paint has penetration ability, and the coating can penetrate through small holes in plain ground, which improves the bonding skills between plain ground and floor paint. However, the existence of oil pollution closes the space of tiny holes, making the floor coating can not bond well with the plain ground, and the area with oil pollution is easy to fall off.

    因此脏乱的地面会影响着其粘接附着力,环氧地坪施工前则需要进行基面处理,这样才能凸显出环氧地坪涂料的特性,以及地坪地面达到平整无缝、光亮美观的效果。

    Therefore, dirty ground will affect its adhesion, epoxy flooring needs to be treated before construction, so as to highlight the characteristics of epoxy flooring paint, as well as the floor to achieve smooth, seamless, bright and beautiful effect.

    如何正确的处理基面呢?

    How to deal with the base surface correctly?

    首先,看下地坪施工的基面要求:

    First of all, look at the requirements of the ground floor construction:

    l 混凝土强度要求C25以上;

    The strength of concrete should be above C25.

    l 建议混凝土做原浆收光;

    It is suggested that concrete should be used as raw paste to collect light.

    l 首层建议做防水、防潮处理;

    The first floor suggests waterproof and moisture-proof treatment.

    l 平整度要求2M靠尺最大高差小于3㎜;

    The flatness requires that the maximum height difference of 2M footage is less than 3 inches.

    l 施工温度一般5°C以上,湿度要低于85%;

    The construction temperature is generally above 5 degree C and the humidity is below 85%.

    l 新浇筑混凝土需养护到表面充分干燥后方可施工。

    The newly poured concrete needs to be maintained until the surface is fully dried before it can be constructed.

    基面处理步骤:

    Base surface treatment steps:

    初步清扫

    Preliminary cleaning

    1、用扫把将待处理地面上的垃圾清理干净;

    1. Clean up the garbage on the ground with a broom.

    2、有水的地方首先应该切断水源,并清除表层积水, 再设法使地面干燥(如果待施工地面为一楼或地下室,还应考虑是否需做防水、防潮处理);

    2. Where there is water, the water source should be cut off first, and the surface water should be removed, then the ground should be dried (if the ground is to be constructed on the first floor or basement, the need for waterproof and moisture-proof treatment should also be considered);

    3、检查防水、防潮效果。(a、未达到防水防潮要求,不可做涂料层,b、检测时,每一百平米用一平米的尼龙薄膜覆盖,四周用胶带纸封闭,过48小时看颜色有无变化。颜色变深或有水珠即表示防潮失败。)

    3. Check the effect of waterproof and damp-proof. (a) Not to meet the requirements of waterproof and moisture-proof, do not make coating. B. When testing, each 100 square meters is covered with one square meter of nylon film, and all around is sealed with tape paper. After 48 hours, see if the color changes. Darker colours or droplets of water indicate a failure to moistureproof.

    4、有油污的地方应用有机溶剂等(比如天那水,二甲苯等)洗净,擦干;

    4. Use organic solvents (e.g. Tiannashui, xylene, etc.) to clean and dry oil-stained areas.

    5、有油漆或其它不明污染物的地方应作适当处理,其方法有打磨, 有机溶剂擦洗等;

    5. Where there are paints or other unknown pollutants, proper treatment should be made by grinding, scrubbing with organic solvents, etc.

    6、按实际情况而定,是否需要再做一次清扫;

    6. According to the actual situation, do you need to do another cleaning?

    打磨地面

    Ground grinding

    1、用吸尘打磨机全面打磨:

    1. Full grinding with vacuum grinder:

    针对水磨石基面和较光滑致密的水泥基面,提供适当粗糙度。

    For terrazzo base surface and smooth and compact cement base surface, appropriate roughness is provided.

    ①去除表面不易清扫的浮尘且打毛基面, 以增强涂层与地面的结合力;

    (1) Remove the surface dust which is not easy to clean and polish the base surface, so as to enhance the adhesion between the coating and the ground;

    ②将待处理基面的高低不平处基本磨平, 起找平作用。

    (2) Leveling the unevenness of the base surface to be treated.

    2、手磨机打磨:

    2. Hand grinder grinding:

    对于大打磨机打不到的地方或打不掉之油污等可用手磨机打磨, 注意应选用专用砂轮片。

    Special grinding wheels should be selected for grinding where the large grinder can't be used or oil stain can't be removed by hand grinder.

    3、砂纸打磨:

    3. Sandpaper grinding:

    对于大打磨机和手磨机打不到的地方,或不必用手磨机打磨的区域,如生产线下面,可用砂纸打磨或用钢丝刷处理等方法达到打磨效果。

    For areas where large grinders and hand grinders can not be polished, or where hand grinders are not necessary, such as under the production line, sandpaper grinding or wire brush treatment can be used to achieve grinding effect.

    细节处理

    Detail processing

    再次清扫, 贴保护胶纸:

    Clean up again and stick protective tape:

    1、彻底清理地面灰尘,对于不易清洁的卫生死角, 可用吸尘器吸尘;

    1. Clean up the ground dust thoroughly. For the sanitary dead corner which is not easy to clean, vacuum cleaner can be used.

    2、将墙脚,机脚,或其它应受保护的地方用胶带纸包扎保护;

    2. Cover the wall foot, machine foot, or other protected areas with tape paper for protection.

    旧地面处理:

    Old ground treatment:

    地面若为旧地面,则进行以下处理:

    If the ground is old ground, the following treatment shall be carried out:

    1、凹凸不平的地面使用水性刚强砂浆进行填平修补,达到地面平整要求;

    1. Waterborne rigid mortar is used for filling and repairing rough ground to meet the requirements of ground leveling.

    2、修补较宽的裂缝和坑洞,最好用快干无溶剂环氧树脂涂料调石英砂修补;

    2. To repair wider cracks and pits, it is better to use quick-drying solvent-free epoxy resin coatings mixed with quartz sand.

    3、对于伸缩缝,先清理干净里面的杂物,再用快干无溶剂环氧树脂中涂拌石英砂修补;

    3. For expansion joints, first clean the debris inside, and then use quick-drying solvent-free epoxy resin mixed with quartz sand to repair.

    4、对于细小裂缝应先用磨机切成V型槽,并用快干无溶剂环氧砂浆进行灌缝处理;

    4. For small cracks, the grinder should be used to cut into V-grooves and the fast-drying solvent-free epoxy mortar should be used to grout the cracks.

    5、固化后用砂纸打磨平整,清扫地面。

    5. After curing, sandpaper is used to polish and smooth the ground.

    3、按实际情况而定,是否需要再做一次清扫。

    3. According to the actual situation, do you need to do another cleaning?

    7、若为旧地面:用铲刀铲除基面(旧油漆、空鼓、起壳层)再进行清扫打磨处理。

    7. If it is an old ground, remove the base (old paint, empty drum, shell) with a shovel knife and then clean and polish it.
