雨季影响环氧地坪施工吗?环氧地坪施工中有哪些注意事项?环氧地坪漆涂装质量三分取决于涂料七分取决于施工,优质涂料若不采用严格的施工工艺不会得到优良的效果,因此施工对于环氧地坪漆来说是非常重要的。我们首先谈下湿度对于环氧地坪施工的影响: 湿度,指的是空气中水分的含量,一般用百分比来表示。如果有结露现象出现,说明空气的相对湿度达到百分之百。根据环氧地坪漆施工要求规定,当空气相对湿度高于85%时,是不能进行环氧地坪漆施工的,因为容易出现泛白、裂纹等弊病。湿度不仅影响环氧地坪漆的施工,更是会影响环氧地坪漆固化,湿度指数在过大的情况下才影响地坪涂装,它的影响往往大于人们的想象。

Does the rainy season affect floor construction? What should we pay attention to in the construction of epoxy floor? The coating quality of epoxy floor paint depends on three parts of the coating and seven points of the coating depend on the construction. If the strict construction technology is not used, the excellent effect will not be obtained. Therefore, the construction of epoxy floor paint is very important. First of all, we talk about the influence of humidity on the construction of epoxy flooring: humidity refers to the content of moisture in the air, which is generally expressed by percentage. If condensation occurs, the relative humidity of air reaches 100%. According to the construction requirements of epoxy floor paint, when the relative humidity of air is higher than 85%, the construction of epoxy floor paint can not be carried out, because it is prone to white, cracks and other defects. Humidity not only affects the construction of epoxy floor paint, but also affects the curing of the floor paint. When the humidity index is too large, it affects the floor paint. Its influence is often greater than people imagine.

湿度过高,会引起涂装表面结露,凝结的水会对固化剂造成破坏引起涂膜发白、失光、发黏、回黏等现象,大大降低表面装饰效果,严重时造成返工。特别无溶剂面漆,表干时间一般较长,在涂漆后马上下雨或在冬春季的傍晚涂漆都是有危险的.但有时因为业主要求工期,理想的天气条件不易出现,这时就需采取措施改善涂装小环境了,如开启空调加温和抽湿。

Excessive humidity will cause dew on the surface of the coating. Condensed water will destroy the curing agent and cause the phenomenon of whitening, losing light, sticking and Re-sticking of the coating, which will greatly reduce the decorative effect of the surface and cause rework in serious cases. Especially solvent-free topcoat, the surface drying time is generally longer. It is dangerous to paint in the rain immediately after painting or in the evening of winter and spring. But sometimes because the owner requests a time limit, ideal weather conditions are not easy to appear. At this time, measures need to be taken to improve the small environment of painting, such as opening air conditioning to warm and dehumidify.

温度对于环氧地坪施工的影响:

The influence of temperature on epoxy floor construction:

地坪施工温度应控制需在10-35℃范围内,超出此范围需采用特殊地坪涂料品种;地坪涂料(特别是面漆)涂装与固化过程中(表干前),底材表面温度应高于露点3℃以上,以防底材及湿膜表面水汽凝结影响涂层附着力和表面效果。

The construction temperature of floor should be controlled in the range of 10-35 C, and special floor coatings should be used when exceeding this range. In the process of coating and curing of floor coatings (especially topcoats) before surface drying, the surface temperature of the substrate should be higher than dew point 3 C, in order to prevent water vapor condensation on the surface of the substrate and wet film from affecting the adhesion and surface effect of the coating. Fruit.

①夏季施工要求

Summer construction requirements

夏季在清晨或傍晚施工较为适宜。施工时需测量温度,当气温超过35℃时,为了施工人员的健康和优质的涂膜质量,应避免施工。在湿度大和雨天施工,需测量相对湿度和露点温度,随时检查已干燥涂膜的质量,当出现裂纹、橘皮、脱落等现象时,及时补涂维修。对于双组分涂料,在配制稀释剂和固化剂时应尽量采用慢挥发溶剂,混合甲乙组分时,采用少量、多次勤配的原则,防止出现涂料固化中放热过快的现象而引起涂料报废。温度过高,双组分涂料特别是无溶双组分涂料易出现爆聚现象,即涂料反应过快,大量放热而使涂料使用期缩短。高温下施工时,虽然涂料干燥速率会较快,但即使测定已实干,也要按照一定的涂装间隔进行下一道涂装。

It is suitable to construct in the morning or evening in summer. Temperature should be measured during construction. When the temperature exceeds 35 C, construction should be avoided in order to improve the health of construction personnel and the quality of coating film. In wet and rainy days, it is necessary to measure relative humidity and dew point temperature, inspect the quality of the dried film at any time, and repair it in time when cracks, orange peel and peeling occur. For two-component coatings, slow volatile solvents should be used as far as possible in the preparation of diluents and curing agents. When mixing A and B components, the principle of a small amount and many times of diligent mixing should be adopted to prevent the phenomenon of excessive heat release in the curing of coatings from causing paint scrap. When the temperature is too high, two-component coatings, especially insoluble two-component coatings, are prone to explosion. That is to say, the reaction of coatings is too fast and a large amount of heat release shortens the service life of coatings. In high temperature construction, although the drying rate of the coating will be faster, the next coating should be carried out according to a certain painting interval even if the measurement is dry.

②冬季施工要求

(2) winter construction requirements

在有雾或被涂物表面蒙有水汽及霜雪时,不宜进行户外施工。施工时被涂物表面温度应高于露点3℃以上,气温不应低于涂料干燥规定的最低温度。在10℃以下施工时,一般应在上午10点至下午3点作业,充分利用气温较高的时间,组织施工力量,尽快完工。尽量选择专用型冬用固化涂料。涂料若过于粘稠不易涂装时,可加入小于5%的挥发速率较快的溶剂,如丙酮、乙酸乙酯、乙酸丁酯等。可将涂料贮存在温暖的环境中或用热水、蒸汽加热涂料(可能造成涂料质量的下降)。当温热涂料时,除非采用特别的涂料加热设备,其温度不要超过38℃。涂料闪点低于38℃时,加热温度不得超过其闪点。注意打开包装桶盖时,避免水汽的进入,严禁用明火或电火直接加热,加热时必须注意安全。与常规涂装要求相比,在保证漆膜厚度的前提下,可适当增加涂装道数,延长涂装间隔。在测定涂膜实干后,再涂装下一道涂料。

When there is fog or the surface of the coating is covered with water vapor and frost and snow, it is not suitable for outdoor construction. During construction, the surface temperature of the coating should be higher than dew point 3 C, and the temperature should not be lower than the minimum temperature prescribed by the drying of the coating. When construction is under 10 (?) C, it is generally necessary to work from 10 a.m. to 3 p.m. to make full use of the time when the temperature is high, organize the construction force and complete the work as soon as possible. As far as possible, select special winter curing coatings. If the paint is too thick and difficult to be coated, solvents with a faster volatilization rate of less than 5% can be added, such as acetone, ethyl acetate, butyl acetate, etc. Coatings can be stored in a warm environment or heated by hot water or steam (which may result in a decline in the quality of the paint). When a thermothermal coating is applied, the temperature shall not exceed 38 C unless a special coating heating device is used. When the flash point of the coating is below 38 C, the heating temperature shall not exceed its flash point. Pay attention to opening the lid of the packaging barrel, avoid water vapor entering, prohibit direct heating with open fire or electric fire, and pay attention to safety when heating. Compared with the conventional coating requirements, the number of coating paths can be increased and the coating interval can be prolonged on the premise of guaranteeing the film thickness. After testing the film dry, the next coat is applied.

为了充分保证环氧地坪施工质量。施工过程中还必须注意以下事项:

In order to fully guarantee the construction quality of epoxy floor. In the construction process, the following matters must be paid attention to:

1、施工环境搬运到施工现场的材料务必放在能够避免风、雨以及直射阳光的地方。如阳光直接晒到施工面上,在基层中或还没有完全硬化的涂膜里含有的空气离子会因排出不畅而产生小气孔,因此要用报纸或塑料布盖住整个窗户。为了防止风从外面吹人粉尘污染施工面,施工期间膜完全硬化期间应把门、窗、缝隙等透风处用护面胶带封好。同时需防止缝隙吹来的风带进尘土,注意不应在低于5℃的环境下施工,如有可能可开暖气或空调,下雨时把敞开部分都关闭一避免潮气影响施工面但不要阻碍通风。

1. Material transported to the construction site in the construction environment must be placed in a place where wind, rain and direct sunlight can be avoided. If the sunlight is directly exposed to the construction surface, the air ions contained in the basic layer or in the film which has not yet been completely hardened will cause small air holes due to poor discharge, so the whole window should be covered with newspapers or plastic sheets. In order to prevent the wind from blowing dust from the outside to pollute the construction face, during the construction period when the membrane is completely hardened, the ventilation areas such as doors, windows and crevices should be sealed with protective tape. At the same time, it is necessary to prevent the wind from blowing into the crevice from bringing dust. Attention should not be paid to the construction under the environment of less than 5 C. If possible, heating or air conditioning can be turned on. When it rains, the open part should be closed to avoid dampness affecting the construction surface, but do not hinder ventilation.

2、安全卫生管理方面的要求也很重要。从事施工的人员须经专门培训,对化学产品有一定的知识;施工时须穿工作服、工作鞋、配劳防用品;各种材料不小心沾到皮肤上有时会损伤皮肤,尽快用肥皂清洗干净,严重的送医院救治;各种材料不准接触任何水分(水性环氧地坪涂料除外),施工人员每人须带擦汗用的毛巾,防止施工中汗水滴入地面或材料中;因环氧地坪材料中含微量的可燃物,施工现场严禁烟火,现场的材料不准放置在阳光直

2. Safety and health management requirements are also important. Personnel engaged in construction must be specially trained and have a certain knowledge of chemical products; during construction, they must wear work clothes, shoes and anti-labor articles; when various materials accidentally touch the skin, they sometimes damage the skin, clean it with soap as soon as possible, and send it to hospital for treatment seriously; and all kinds of materials are not allowed to touch any moisture (water ring). Except for oxygen floor coating, each worker should wear a towel to wipe sweat to prevent sweat from dripping into the ground or materials during construction; because epoxy floor material contains trace combustibles, fireworks are strictly prohibited at the construction site, and materials on the site are not allowed to be placed in direct sunlight.
