    为什么环氧地坪漆材料会沉淀?怎么处理

    2019-07-02 09:04:29 无锡盛发地坪科技有限公司 阅读

    环氧地坪漆具有整体无缝、耐磨耐压、耐酸碱等特点,这些优点使环氧地坪漆在地面材料中备受青睐,广泛应用于工业厂房车间、地下停车场等场所。但在进行环氧地坪漆施工时材料有时会出现沉淀,这不仅会影响施工进度,还会影响铺装效果,为什么会出现沉淀现象呢?

    Epoxy floor paint has the characteristics of seamless, abrasion resistance, pressure resistance, acid and alkali resistance. These advantages make it popular in ground materials and widely used in industrial workshop, underground parking lot and other places. But in the construction of epoxy floor paint, the material sometimes precipitates, which will not only affect the progress of construction, but also affect the pavement effect. Why does precipitation occur?环氧地坪漆材料出现沉淀的原因:

    Reasons for precipitation of epoxy floor paint materials:

    1、环氧地坪漆材料颜色多样,生产时需要用到颜料,但是如果颜料达不到使用要求,太粗、分散、密度不达标等都会造成环氧地坪漆材料出现沉淀现象。

    1. The materials of epoxy floor paint are of various colors and need to use pigments in production, but if the pigments can not meet the requirements of use, too coarse, dispersed, density not up to the standard will cause the precipitation phenomenon of epoxy floor paint materials.

    2、环氧地坪漆配料时颜料与基漆发生反应,也会产生沉淀。

    2. When epoxy floor paint is mixed, the pigment reacts with the base paint and precipitates.

    3、环氧地坪漆材料存放的时间太久,当使用时又没有很好的摇匀。

    3. The epoxy floor paint material has been stored for too long and has not been shaken well when used. 如何防止环氧环氧地坪漆材料发生沉淀:

    How to prevent the precipitation of epoxy floor paint materials?

    1、挑选填料尽量选用密度小的,有些颜料如红丹粉、铬黄、铁红、云母氧化铁、沉淀硫酸钡等密度都较大,少用或酌情用密度低的颜填料替代。另外考虑适合的颜基比,一般颜基比不要超过2:1。同时选用的颜填料之问不能相互反应。如锌粉、铝粉.氧化锌等比较活泼,在贮存稳定性不佳的地坪漆涂料中尽量不用或分罐包装。

    1. Select fillers with low density as far as possible. Some pigments such as red powder, chrome yellow, iron red, mica ferric oxide, precipitated barium sulfate and other densities are larger, and less or as appropriate, use low density pigments and fillers instead. In addition, considering the appropriate ratio, the general ratio should not exceed 2:1. At the same time, the selected pigments and fillers can not react with each other. For example, zinc powder, aluminium powder, zinc oxide and so on are more active, and they should not be used or packed separately in flooring paint coatings with poor storage stability.

    2、环氧地坪漆配料时要尽量把颜料磨细,这样才能让颜料更好的分散、融合,这样在环氧地坪施工时就不易出现问题。

    2. When mixing epoxy floor paint, we should grind the pigments as fine as possible, so that the pigments can be better dispersed and fused, so that it is not easy to have problems in the construction of epoxy floor paint.

    3、环氧地坪漆材料生产时加入防沉剂,利用少量助剂的特殊性能,制成触变性涂料,改变涂料悬浮状态,常用的防沉剂有硬脂酸系列、气相二氧化硅、改性膨润土、氢化蓖麻油等。

    3. Thixotropic coatings are prepared by adding anti-settling agent in the production of epoxy floor paint materials and using the special properties of a small amount of additives to change the suspension state of the coatings. The commonly used anti-settling agents are stearic acid series, gas-phase silicon dioxide, modified bentonite, hydrogenated castor oil, etc.

    4、地坪漆涂料贮存应放置在阴凉通风处,定期将地坪漆涂料桶横放、倒置或摇动几次。

    4. Floor paint should be stored in a cool and ventilated place, and the floor paint barrel should be placed horizontally, inverted or shaken several times regularly.

    5、地坪漆不宜放置太久使用,这样会影响涂装效果。

    5. Floor paint should not be placed for too long, which will affect the painting effect.环氧地坪漆材料已经发生沉淀怎么办?

    How to deal with the precipitation of epoxy floor paint material?

    对于已经沉淀的环氧地坪漆材料,如果程度较轻,使用时用搅拌器充分搅拌均匀,然后按照环氧地坪漆施工工艺施工即可。如果沉淀比较严重,已经结块,可以先把可流动部分倒出,用刮铲从容器底部铲起沉淀,研碎后,再把流动介质倒回原先桶中,充分混合。如果通过反反复复这种操作仍旧无法混合,仍有干结沉淀,涂料就只能报废。

    For the precipitated epoxy floor paint materials, if the degree is relatively light, the use of mixers to fully mix evenly, and then according to the construction process of epoxy floor paint can be constructed. If the sediment is serious and has been agglomerated, the movable part can be poured out first, and the sediment can be shoveled from the bottom of the container with a scraper. After crushing, the flowing medium can be poured back into the original barrel for full mixing. If the mixing is still impossible through repeated operations and there is still dry deposition, the paint can only be scrapped.
