    环氧地坪冬季施工注意事项

    2018-11-07 10:11:27 无锡盛发地坪科技有限公司 阅读

    随着冬季的到来,全国大部分地区气温的降低,空气干燥,使环氧地坪涂料难以施工,环氧地坪漆的施工温度一般要求在5度以上,湿度要低于85%,否则不宜施工。而低于5℃,环氧地坪涂料的地面实际效果就比较难保证。国内北方地区的冬季,温度在5℃以下是很常见的事情,那么在这种环境下,环氧地坪的施工都会遇到哪些问题?

    With the arrival of winter, the temperature of most parts of the country has dropped and the air is dry, which makes it difficult to construct epoxy floor coatings. The construction temperature of epoxy floor coatings is generally required to be above 5 degrees and the humidity is below 85%, otherwise it is not suitable for construction. And below 5 degrees, the actual effect of epoxy floor coating is difficult to guarantee. In the winter of northern China, the temperature below 5 is very common, so in this environment, what problems will be encountered in the construction of the floor? 首先来了解一下为什么低温环境下环氧地坪会难以施工:

    First of all, to understand why the epoxy floor in low temperature environment will be difficult to construct:

    1、减慢涂料反应。

    1, slow down the paint reaction.

    双组分的环氧地坪涂料施工,需要现场将甲、乙组分按比例混合,搅拌均匀,让双组分充分反应,这样才能保证地坪的效果。但如果温度低于5℃,反应将会降低或减缓,这会严重影响地坪涂料的固化性能。而固化性能的降低,将导致涂膜表面干得很慢,会增加涂膜被灰尘,杂物,或者昆虫(苍蝇、蚊子)污染的可能。

    In the construction of two-component floor coating, it is necessary to mix the components A and B proportionally in the field, mix evenly, and make the two components fully react, so as to ensure the effect of the floor. However, if the temperature is lower than 5 C, the reaction will be reduced or slowed down, which will seriously affect the curing performance of floor coatings. Decreased curing performance will result in a slow drying of the film surface, which will increase the possibility that the film will be contaminated by dust, debris, or insects (flies, mosquitoes).

    2、黏度成倍增长。

    2, viscosity increases exponentially.

    无溶剂的自流平涂料靠流平性保证地坪的平整度。但低温下,地坪涂料的黏度会成倍增加,流平性能将降低。而不靠流平性的涂料,刮涂时会因为流动、流平性能变差,而出现镘刀痕的缺陷。

    Solventless self leveling coatings ensure smoothness of the floor by leveling. But at low temperatures, the viscosity of the floor coating will increase exponentially and the leveling performance will be reduced. However, without leveling coating, the defect of trowel marks will appear when scraping because of the poor flow and leveling performance.

    3、降低涂膜质量。

    3, reduce the quality of coating.

    由于固化反应减慢,或者完成不能固化,涂膜的强度、硬度、耐磨性都将会降低,而且会更容易出现地坪脱离等问题,严重的影响环氧地坪的使用寿命。

    The strength, hardness and wear resistance of the coatings will be reduced due to the slowdown of curing reaction or the failure of curing, and the problems of floor detachment will occur more easily, which will seriously affect the service life of epoxy floor.

    根据以上几个问题,我们可以这样来解决:

    According to the above questions, we can solve this problem.

    1、隔开低温时段:环氧地坪施工时,在白天的上午10点至下午3点内施工,尽量隔开低温时段,尽可能的减少低温的影响。

    1. Separate the low temperature period: When constructing the epoxy floor, it should be constructed from 10:00 a.m. to 3:00 p.m. in the daytime, and try to isolate the low temperature period to minimize the impact of low temperature.

    2、增加室温:可以把室内的温度提高,也可以在冬季进行环氧地坪漆施工,北方有条件的可以在环氧地坪漆施工前和施工的过程中供应暖气。

    2. Increase room temperature: you can raise the indoor temperature, you can also carry out the construction of epoxy floor paint in winter. Northern conditional can supply heating before and during the construction of epoxy floor paint.

    3、添加溶剂:为了解决地坪漆在低温下黏度大,缺乏流动性难搅拌,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,这样可以增加地坪漆的流动性。

    3. Solvent addition: In order to solve the problem of high viscosity at low temperature and lack of fluidity and difficult stirring, solvents with less than 5% volatilization rate can be added, such as acetone, ethyl acetate, butyl acetate and so on, so as to increase the fluidity of floor paint.

    4、施工时一定要搅拌均匀,由于低温会使固化时间变长,所以要确定漆已经干透才能施工第二道漆。

    4. Must mix evenly during construction, because low temperature will make solidification time longer, so it is necessary to make sure that the paint has dried thoroughly before the construction of the second paint.

    为了在低温环境下同样能达到理想的施工效果,避免漆膜弊端的出现,还有很多方面需要我们去注意:

    In order to achieve the same ideal construction effect in low temperature environment and avoid the appearance of drawbacks of paint film, we need to pay attention to many aspects:

    1、冬季施工要注意:首先紧闭门窗,这样一方面可以保证室内温度,另一方面也可以避免室外风沙吹刮到未干的地面上,出现毛糙不平整的现象。等涂料充分干燥后,再敞开门窗通风,并注意把握时间。

    1. Winter construction should pay attention to: first, close doors and windows, so that on the one hand can ensure indoor temperature, on the other hand, can also avoid outdoor wind and sand blowing to the dry ground, rough and uneven phenomenon. When the paint is fully dried, open doors and windows to ventilate and pay attention to time.

    2、油工在喷刷各种涂料时,应严格按照产品说明中的温度和湿度涂刷,涂施工环境的温度不能低于5℃,湿度不宜大于80%。其中,常用的混色涂料施工时环境温度应在0℃以上,清漆施涂时的环境温度则不得低于8℃。

    2. Oil workers should brush all kinds of coatings strictly according to the temperature and humidity in the product description. The temperature and humidity of the application environment should not be lower than 5 C and should not be greater than 80%. Among them, the ambient temperature of the commonly used mixed color coatings should be above 0 while the ambient temperature of varnish should not be below 8.

    3、在实色漆工艺中如使用腻子或水灰,不能刮涂过厚,并且必须做到干透后彻底打磨,达到:地面平整、用指甲扣不掉漆、手感光滑,否则会导致开裂、脱落现象出现。

    3. If putty or water ash is used in solid-color paint process, it should not be scratched and painted too thick, and it must be thoroughly polished after drying to achieve: flat ground, nail buckle can not remove paint, smooth handle, otherwise it will lead to cracking and peeling phenomenon.

    4、在涂刷各种涂料时,应严格按照产品说明中的要求施工,严格控制稀释比例。

    4. When painting all kinds of coatings, we should strictly follow the requirements of the product description and strictly control the dilution ratio.

    5、冬季寒冷,工人习惯抽烟或生火取暖,这个时候一定要注意安全意识,不要再涂料堆放地附近生火或吸烟,否则一旦引燃,桶装涂料可能会引发爆炸。

    5. In cold winter, workers are accustomed to smoking or lighting a fire for heating. At this time, they must pay attention to safety awareness and stop lighting a fire or smoking near the place where the paint is stacked. Otherwise, once ignited, the barreled paint may cause explosion.

    6、严禁一次性厚涂,防止喷涂过厚导致出现发白、起泡和针孔。

    6, strictly prohibit one-off thick coating to prevent excessive spraying resulting in whitening, foaming and pinholes.

    7、基材施工前必须进行有效的封闭处理,避免出现漆膜发白、脱落等弊端。

    7, the substrate must be effectively sealed before construction to avoid whitening and falling off.

    8、严禁采用超量使用固化剂来提高干燥速度,否则容易导致漆膜过脆引起开裂。不建议使用干速过快的固化剂。在气温较低时,有些厂家过分追求干速,而使用干速过快的固化剂,这将会导致漆膜出现开裂、阴阳面、失光等漆膜弊端。

    8. It is strictly forbidden to use excessive curing agent to improve drying speed, otherwise it is easy to cause the film to be too brittle and crack. It is not recommended to use fast curing agents. When the temperature is low, some manufacturers excessively pursue drying speed and use curing agent with too fast drying speed, which will lead to film cracking, Yin and Yang surface, loss of gloss and other drawbacks.

    9、请配套使用产品,随着气温变冷,注意冬用稀释剂配套使用,减少因配套不良导致的不必要损失。

    9. Please use the matching products. As the temperature becomes colder, pay attention to the matching use of winter diluents to reduce unnecessary losses caused by poor matching.

    10、使用厢式货车运输施工材料、水性涂料、胶类,应用保温材料封包后运输避免冻坏。水性涂料、胶类应存放在温度较高的房间,避免放在阳台、北向房间防止冻坏。

    10. Use Van trucks to transport construction materials, water-borne coatings and glues. Use thermal insulation materials to avoid freezing damage. Water-borne coatings and glues should be stored in rooms with high temperatures. Avoid putting them on balconies and northbound rooms to prevent frost damage.

    传统观念认为的冬季不宜施工,其实是因为有许多不便,并不是不能施工,我们在施工前搞清楚会遇到的问题,从各个方面进行预防,把握好尺幅,冬季施工反而会有意想不到的效果。

    The traditional concept that winter construction is not suitable, in fact, because there are many inconveniences, not can not be constructed, we will find out the problems encountered before construction, from all aspects of prevention, grasp the scale, winter construction will have unexpected results.
