环氧地坪施工前的设计和专业化施工队伍的组织对基层的检查和处理正确的施工组织和质量监督等过程的全程控制。在无锡环氧地坪漆施工前,须清楚了解查看基面状况,下面介绍一般环氧地坪工业环氧地坪漆涂料涂装对地面基层的要求及常见的处理方法。1)水泥基面牢固、结实、不起壳,应杜绝砂浆起壳现象,混凝土层与砂浆找平层最好一起浇筑。若先浇筑混凝土层,则要求砂浆层的厚度不低于40MM,对叉车道的要求则更厚。有关坡度应符合设计要求,允许偏差值的2%,并且不大于30MM。
(2)要求表面不起砂,硬度高,没有水泥粉化现象。新浇筑的水泥砂浆要充分保养。水泥基面平坦,无凹凸不平、蜂窝麻面、水泥疙瘩、其他涂料、乳胶漆、泡泡糖等残渣。(3)表面干燥,含水率小于6%,无油污,PH值应在6.0~8.0;水泥地面养护期过后进场施工前5D,基层不能再用水冲洗或被湿润。
(2) No sand on the surface, high hardness and no cement powdering are required. The newly poured cement mortar should be fully maintained. The cement base surface is flat, without rugged, honeycomb linen, cement bumps, other coatings, latex paint, foam sugar and other residues. (3) The surface is dry, the moisture content is less than 6%, no oil pollution, and the PH value should be 6.0-8.0. After the maintenance period of cement ground, the base can no longer be washed or wetted with water 5 D before construction.
2、基层的检查与预处理基层是环氧树脂地坪涂料的基础,要进行详细检查与分析,以确定其处理措施。
2. The inspection and pretreatment of the base is the basis of epoxy floor coatings. Detailed inspection and analysis are needed to determine the treatment measures.
(1)测量抗压强度。工业环氧地坪的抗压强度不应低于24MPa,为满足某些承重要求,还可能需要更高的强度,应使用回弹仪进行强度测量,或取芯块实测抗压强度。
(1) Measure the compressive strength. The compressive strength of industrial floors should not be less than 24 MPa. In order to meet some important requirements, higher strength may be needed. Strength measurement should be carried out by rebound meter or coring.
(2)确定黏结强度。混凝土基层表面几毫米厚度内通常是水泥浆形成的低强度层。因水泥水化反应导致的收缩,温度变化或荷载的反复作用等产生的应力,会导致黏结强度降低。黏结强度不应低于1.5MPa。
(2) Determine the bond strength. The low strength layer formed by cement slurry is usually in the thickness of several millimeters on the surface of concrete base. The stress caused by shrinkage, temperature change or repeated action of load caused by hydration reaction of cement will lead to the decrease of bond strength. The bond strength should not be less than 1.5 MPa.
(3)基层含水率。只有在水泥基层含水率不大于6%的情况下才能进行涂料的施工,所以含水率的测量尤为重要。确定基层含水率的最佳方法是塑料薄膜覆盖实验法,即将至少1mX1m的聚乙烯薄膜用胶带封粘在混凝土面上,待至少24小时后,根据塑料薄膜上出现冷凝水的数量确定含水率。
(3) Water content of grass-roots. Only when the moisture content of cement base is not more than 6%, can the coating be applied, so the measurement of moisture content is particularly important. The best method to determine the moisture content of the base course is the plastic film covering experiment method, that is, at least 1mX1m polyethylene film is sealed on the concrete surface with tape, and after at least 24 hours, the moisture content is determined according to the amount of condensation water appearing on the plastic film.
(4)环境温度。忽略施工环境温度因素可导致环氧地坪的质量缺陷,例如黏结强度降低、水印、空洞、不规则表面及硬化不兖分等。因此,对于环境温度(气温)、基层表面的温度、露点温度等数所数据,在施工中必须每天测量数次。
(4) Environmental temperature. Ignoring the temperature factors of construction environment can lead to quality defects of epoxy floor, such as reduced bond strength, watermarking, voids, irregular surface and hardening. Therefore, the environmental temperature (air temperature), the surface temperature of the grass-roots, dew point temperature and other data, in the construction must be measured several times a day.
(5)基层清理。对于油脂、机油或有机酸、无机酸或水泥浆所引起的污染,如果不进行彻底清除,将影响环氧地坪漆涂料层的黏结性能。因此地,必须用机械方法清理表面,并通过测定黏结强度进行检查。
(5) grass-roots clean-up. For oil, oil or organic acid, inorganic acid or cement slurry pollution, if not thoroughly removed, will affect the bonding performance of epoxy floor paint coating. Therefore, the surface must be cleaned mechanically and checked by measuring the bond strength.
3、基层处理
3. Grass-roots treatment
(1)为使无锡环氧地坪涂料的施工达到良好的效果,对于尚未找平的地面,应首先施工水泥找平层以进行找平处理。土建方找平时,在水泥初凝时,用专业地面机械对地面进行磨平处理。经过基层处理再涂装的环氧涂装地坪的表面会更平整、光亮,使用寿命也会提高。
(1) In order to achieve good results in the construction of epoxy floor coating, cement leveling layer should be first applied to leveling the ground that has not yet been leveled. When the cement is initially solidified, the civil engineer uses professional ground machinery to grind the ground. The surface of epoxy-coated floor will be smoother, brighter and the service life will be improved after basic treatment and re-coating.
(2)待水泥层干燥后(大约28天),用打磨机对地面进行整体打磨处理,使其表面平整,水泥毛细孔全部敞开。
(2) After the cement layer is dried (about 28 days), the whole ground is polished with a grinder to make the surface smooth and the cement capillary holes open.
(3)对于有油污(食用油、机油)的基层,先用表面处理剂喷洒于用水冲湿的地表面,反复擦洗,直到无油污为止。
(3) For the base layer with oil contamination (edible oil, engine oil), the surface treatment agent is sprayed on the surface wetted with water and scrubbed repeatedly until there is no oil contamination.
