    聚氨酯环氧地坪漆涂装粗糙的原因及解决方法

    2018-11-07 11:50:24 无锡盛发地坪科技有限公司 阅读

    聚氨酯环氧地坪漆涂装出现粗糙现象有以下几个方面的原因:一、施工环境和环氧地坪漆漆膜干燥过程中的环境不干净,灰尘多,使灰尘落在还处于流平阶段的漆膜上,最终导致灰尘黏附于环氧地坪漆涂膜上而使涂膜出现粗糙现象。

    The reasons for the roughness of polyurethane epoxy floor paint are as follows: 1. The construction environment and the drying process of the epoxy floor paint film are not clean and dusty, which makes the dust fall on the film which is still in the leveling stage, and eventually causes the dust to adhere to the floor paint film and makes the film rough.

    二、环氧地坪漆涂料涂装前没有过滤,混入机械杂质,这些机械杂质与涂料一起被涂装在了被涂物上,当涂膜干燥后机械杂质就突显在环氧地坪漆涂膜上了,最后导致涂膜出现了粗糙的现象。

    2. The epoxy floor paint is not filtered before painting, and is mixed with mechanical impurities. These mechanical impurities are coated on the coatings together with the coatings. When the coatings are dried, the mechanical impurities are highlighted on the floor paint coatings, which eventually leads to the appearance of rough coatings.

    三、由于聚氨酯环氧地坪漆涂料是双组分或多组分涂料,又属于化学固化型涂料,所以当涂料混入固化剂后,涂料就开始起化学作用,地坪漆涂料黏度就慢慢升高,到特定时间后就开始胶化,直接最后固化成膜。当涂料开始胶化仍继续施工时,地坪漆涂膜就可能出现粗糙了。

    3. Because the polyurethane epoxy floor paint is a two-component or multi-component coating, and belongs to chemical curing coating, when the paint is mixed with curing agent, the paint begins to play a chemical role, and the viscosity of the floor paint gradually increases, and begins to gelatinize after a specific time, and finally solidifies directly into a film. When the paint starts to gel and continues to be constructed, the paint film on floor paint may be rough.

    四、施工现场温度太高,稀释剂挥发太快,环氧地坪漆涂料涂到被涂物上已经没有流平的时间就已经开始固化,因此就会出现粗糙的现象。

    Fourth, the construction site temperature is too high, the diluent volatilizes too fast, the epoxy floor paint coated on the coating has no leveling time has begun to solidify, so there will be rough phenomenon.

    出现粗糙现象如何解决呢?

    How to solve the problem of roughness?

    做好施工现场和待干现场的清洁工作,杜绝灰尘对环氧地坪漆漆膜的污染。涂料施工前,按产品说明书要求,调配好(按各组分的配比配好涂料,再用稀释剂调整到适合施工的黏度)地坪漆涂料后,用120目纱布把涂料过滤后再施工,即可避免由于机械杂质所引起的促擦现象了。

    Do the cleaning work at the construction site and dry site, and eliminate the pollution of the dust on the epoxy floor paint film. Before coating construction, according to the requirements of product specifications, after mixing the floor paint (according to the proportion of each component, and then adjusting the diluent to the suitable construction viscosity), the floor paint can be filtered with 120 mesh gauze and then constructed, which can avoid the friction-promoting phenomenon caused by mechanical impurities.

    环氧地坪漆涂装前,根据涂料的可施工时间计算好涂料的用量,再进行涂料配比和稀释等后续工作,用多少配多少,不能多配。如发现有胶化的地坪漆涂料就不能再用。换用适合口径的喷枪,调整好空气压力和适宜的喷涂距离等。换用慢干的高沸点稀释剂。

    Before the epoxy floor paint is painted, the amount of the paint should be calculated according to the construction time of the paint, and then the following work such as the proportion and dilution of the paint should be carried out. If there is a gelatinized floor paint, it will not be used again. Replace the spray gun that fits the caliber, adjust the air pressure and the appropriate spraying distance. Replace the slow drying high boiling point diluent.

    处理好下层,从底层开始就要按施工要求做好,中层要杜绝粗糙现象,面层施工前一定要把中层清理干净,确认无灰尘后再施工,这样就可以解决环氧地坪漆该类的粗糙现象了。

    To deal with the lower layer well, we should do a good job according to the construction requirements from the bottom layer. The middle layer should eliminate the rough phenomenon. Before the surface layer construction, we must clean the middle layer, confirm that there is no dust before construction, so that we can solve this kind of rough phenomena of epoxy floor paint.
