无锡环氧地坪漆最佳施工温度应该控制在多少?

标签:混凝土密封固化剂 | 混凝土密封固化剂厂家

环氧地坪漆的最佳施工环境温度是10-35℃,一般来说5℃以上也可施工,低于5℃,环氧地坪漆的施工效果就比较难保证。温度低于5℃ ,双组分环氧地坪漆涂料的固化反应历程减慢或停止,会严重影响环氧地坪涂料的固化性能,表现为涂膜表干太慢,容易被灰尘等杂物污染,影响表现和装饰效果;固化过程延长,甚至不能完全固化,涂膜性能严重降低,如强度、硬度降低,耐磨性变差,直接影响使用寿命。对于无榕剂自流平涂料的影响则更大,表现为涂料的黏度成倍增长,流动、流平性能变差,施工时产生刀痕等缺陷。事实上更低的温度,无溶剂环氧树脂自流平涂料几乎是不可用的。

The optimum construction environment temperature of epoxy floor paint is 10-35 C. Generally speaking, it can also be constructed above 5 C. The construction effect of epoxy floor paint is difficult to guarantee when it is below 5 C. The curing process of two-component epoxy floor paint slows down or stops when the temperature is below 5 C, which will seriously affect the curing performance of the floor paint. It is shown that the surface of the film is too slow to dry and is easily polluted by impurities such as dust, which will affect the performance and decorative effect. The curing process is prolonged or even can not be completely cured, and the performance of the film is seriously reduced, such as strength, hardness, wear resistance and straightness. Connection affects service life. The influence on the self-leveling coating without banyan agent is greater, which shows that the viscosity of the coating increases exponentially, the flow and leveling properties become worse, and knife marks are produced during construction. In fact, solventless epoxy self-leveling coatings are almost unavailable at lower temperatures.而温度高于35℃时 ,无溶剂自流平涂料的使用期会明显缩短,涂料很快增稠并干结报废,甚至出现爆聚现象。因此要求少量多次配料, 配好的漆尽快倒于地板上,增加散热。溶剂型涂料在高温下或者气流速度大的地方如门口、过道等处施工容易出现桔皮、皱纹、针孔等弊病,是由于溶剂挥发过快引起的,要补加高沸点、低挥发速率的稀释剂调整解决。

When the temperature is higher than 35 C, the service life of solventless self-leveling coatings will be significantly shortened, and the coatings will soon thicken, dry out and scrap, or even burst. Therefore, a small number of ingredients are required, and the paint is poured on the floor as soon as possible to increase heat dissipation. Solvent-based coatings are prone to orange peel, wrinkles, pinholes and other defects when they are applied at high temperature or in places with high airflow speed, such as doorways and corridors. It is due to the excessive volatilization of solvents, which should be solved by adding diluents with high boiling point and low volatilization rate.避免温度过高对环氧地坪漆施工产生影响的办法:

How to avoid the influence of excessive temperature on the construction of epoxy floor paint:

1、尽量避免高温时段施工,可以采用早晚时段分叉施工,在使用各种材料前应先将乙组充分搅拌后,再按比例将甲、乙组分倒入搅拌桶搅拌均匀,熟化后再倒入石英粉或粉料,均匀搅拌后使用。

1. Avoid construction in high temperature period as far as possible. Bifurcation construction in early and late periods can be adopted. Before using various materials, group B should be fully stirred before mixing, then component A and B should be poured into the mixing barrel in proportion to mix evenly, then quartz powder or powder should be poured into the mixing barrel after ripening, evenly mixing and using.

2、夏季高温面涂更会轻微分色,灰、蓝色出现的可能更大,应充分搅拌后再使用;

2. High-temperature surface coating in summer will be more light color, gray and blue appear more likely, should be fully stirred before use;

3、夏季温度过高时,配料后应尽快使用,一般再30分钟内使用完毕,以避免材料凝结;

3. When the temperature is too high in summer, the ingredients should be used as soon as possible, usually within 30 minutes to avoid material condensation.

4、采用人工降温措施降低施工环境温度;

4. Artificial cooling measures are adopted to reduce the construction environment temperature.

5、为保证施工环境的相对湿度,可采用人工对施工现场加湿;

5. In order to ensure the relative humidity of the construction environment, artificial humidification can be used on the construction site.

6、施工后的现场应确保有专人照看,以免因温度的过高导致环氧地坪干缩裂缝。

6. On site after construction, special care should be ensured to avoid shrinkage cracks of epoxy floor caused by excessive temperature.避免温度过低对环氧地坪漆施工产生影响的办法:

How to avoid the influence of low temperature on the construction of epoxy floor paint:

1、隔开低温时段

1. Isolation of Low Temperature Period

环氧地坪漆施工时,尽量隔开低温时段,上午10点后再开始施工,下午3点停止施工,减少低温的影响。

During the construction of epoxy floor paint, try to isolate the low temperature period, start construction after 10 a.m. and stop construction at 3 p.m. to reduce the impact of low temperature.

2、增加室温

2. Increase room temperature

增加室内温度,把温度提高到5度以上,这样也可以在冬季施工。北方很多厂房有供暖气,可在施工前和施工中开放暖气供应。

Increase the indoor temperature, raise the temperature to more than 5 degrees, which can also be constructed in winter. Many factories in North China have heating, which can be opened before and during construction.

3、添加溶剂

3. Adding Solvents

可添加小于5%的挥发速率较快的溶剂,如丙酮、醋酸乙酯、醋酸丁酯等。这样可以解决环氧地坪漆在低温下黏度大,缺乏流平性的问题。

Solvents with less than 5% volatilization rate can be added, such as acetone, ethyl acetate, butyl acetate, etc. This can solve the problem of high viscosity and lack of leveling of floor paint at low temperature.

4、涂料加热

4. Coating heating

将涂料放置在温暖的环境,或用蒸汽、热水进行加热。但要注意不要让蒸汽或热水进入涂料内,并且热水温度控制在38度以下。

Place the paint in a warm environment or heat it with steam or hot water. But be careful not to let steam or hot water into the paint, and the temperature of hot water should be controlled below 38 degrees.
