塑假山易掉色的原因有哪些?

经常会看到一些塑假山,刚建成两三年的时间,有的曾经褪为水泥色,有的以至呈现了脱壳现象。掉色对塑假山的影响是宏大的,首先影响假山的美观,其次失去颜色层的防护,塑假山的防水性也大大降低。南京远太经过对业内100多项案例的剖析,得出了塑假山易掉色的缘由,今天就为大家解说解说。
  It is common to see some plastic rockeries, which have faded to cement color in two or three years since they were built, and some even show shelling phenomenon. The influence of discoloration on plastic rockery is magnificent. First, it affects the beauty of rockery, secondly, it loses the protection of color layer, and the waterproof of plastic rockery is greatly reduced. Through the analysis of more than 100 cases in the industry, Nanjing Yuantai has come to the conclusion that the plastic rockery is easy to fade. Today, it will explain for you.
  我们发现,冬季制造的塑假山,后期掉色的可能性加大,经过比拟和剖析,得出冬季制造的塑假山反碱率较高,会大大毁坏颜色层,招致颜色层零落。反碱主要跟假山面层所用的水泥有关,硅酸盐水泥在低温和高水比搅拌的状况下,凝固后遇水会渗碱,在山体作色前,增加抗碱底漆能减少反碱的呈现。
  We found that the plastic rockery manufactured in winter is more likely to fade in the later period. Through comparison and analysis, it is concluded that the plastic rockery manufactured in winter has a higher alkali reversal rate, which will greatly destroy the color layer and cause the color layer to be scattered. Anti-alkali is mainly related to the cement used in the surface layer of rockery. Portland cement will seep alkali when it meets water after solidification under the condition of low temperature and high water ratio stirring. Adding anti-alkali primer can reduce the appearance of anti-alkali before coloring the mountain.
  塑假山易掉色的缘由还有以下几方面:
  The reasons why plastic rockery is easy to fade are as follows:
  一、颜料选用错误,我们假山行业内常用的颜料种类有:氧化铁颜料型、丙烯颜料型、水性色浆型和油漆型,其中丙烯颜料为绘画颜料,主要运用于室内场所,其抗紫外线才能较差,不易运用于室外假山;油漆与水泥基型资料的相容性较差,运用在室内场所是能够的,运用在室外塑假山上,高温下会呈现爆皮现象。
  First, the selection of pigments is wrong. The commonly used pigments in our rockery industry are: iron oxide pigments, propylene pigments, water-based pigments and paints. Among them, propylene pigments are painting pigments, which are mainly used in indoor places. Their anti-ultraviolet ability is poor, and they are not easy to be used in outdoor rockery. The compatibility between paint and cement-based materials is poor, so they can be used in indoor places. In the outdoor plastic rockery, there will be skin explosion under high temperature.

  在室外的状态下,错误的选用丙烯颜料作色于塑假山体上,是招致塑假山掉色的主要缘由。施工中只想到了丙烯颜料的易调色,而没有理解丙烯颜料的耐候性差。
  In the outdoor state, the main reason for the discoloration of plastic artificial hills is the incorrect selection of propylene pigments for color on plastic artificial hills. During the construction, only the easy-to-mix color of propylene pigments was considered, but the poor weatherability of propylene pigments was not understood.
  二、作色前未清算,在塑假山作色前,需求认真的清算假山的表体,不能残留灰尘和砂砾,如灰尘和砂砾残留在山体外表,将会作为隔离物质,将塑假山的砂浆层和颜色层隔分开,随着时间的推移,日晒雨淋的作用将剥离颜色层,招致塑假山掉色。
  2. Unliquidated before coloring. Before coloring, it is necessary to carefully liquidate the surface of the rockery. Dust and gravel, such as dust and gravel, can not be left on the surface of the rockery. It will be used as an isolating material to separate the mortar layer and the color layer of the rockery. With the passage of time, the effect of sunshine and rain will strip the color layer and cause the rockery to fade.
  三、颜料中的抗紫外线添加剂,大多数的塑假山面层是水泥基资料的,选用的颜料也以水性资料的为主,在这些水性资料中,耐候性是要思索的主要条件之一,室外环境日晒雨淋不可防止,乳胶漆和色浆均不能坚持持久,抗紫外线添加剂必不可少,有些塑假山项目作色时,为了俭省本钱,减少耐候剂和抗紫外线乳液的运用,以至不添加,在将来的五年内,颜色将逐步零落。
  3. Anti-ultraviolet additives in pigments, most of the plastic rockery surface layers are cement-based materials, and the selected pigments are mainly water-based materials. In these water-based materials, weather resistance is one of the main conditions to consider. Outdoor environment can not be prevented from sunshine and rain, latex paint and color paste can not persist, anti-ultraviolet additives are indispensable, and some plastic rockery projects. In order to save money and reduce the use of weatherproof and anti ultraviolet emulsion, color will gradually fade in the next five years.
