水分子对挤塑板的影响有哪些?
作者:admin 来源:本站 发布时间:2019-10-31 14:53:56 浏览次数:196
  我相信我们对挤压板并不陌生,毕竟在建筑领域被广泛应用。挤塑板材是一种保温材料,可用于建筑外墙的保温。挤出板材是由聚苯乙烯树脂等助剂挤出而成,具有连续均匀的表层和封闭的蜂窝状结构。导热系数低,保温、耐压性能好。它被广泛应用于各种建筑中。那么水分子对挤出板有显著影响吗?让我们找出答案。
I believe that we are not new to extrusion plate, after all, it is widely used in the field of construction. Extruded board is a kind of heat preservation material, which can be used for the heat preservation of building exterior wall. The extruded sheet is extruded from polystyrene resin and other additives, with continuous and uniform surface layer and closed honeycomb structure. Low thermal conductivity, good heat preservation and pressure resistance. It is widely used in various buildings. So do water molecules have a significant effect on the extrusion? Let's find out.
水分子对挤出板有什么影响
What is the effect of water molecules on extrusion plate
挤出板的吸水率很低,水分子几乎不会对其产生影响,这也是挤出板相对于其他保温材料的明显性能优势。而水分子对聚合物砂浆的影响主要表现在以下几个方面:
The water absorption of the extruded plate is very low, and the water molecules hardly affect it, which is also the obvious performance advantage of the extruded plate compared with other insulation materials. The influence of water molecules on polymer mortar is mainly shown in the following aspects:
1. 通货膨胀
1. Inflation
在连续的雨季。这种聚合物薄膜吸收的雨水比释放的雨水多,雨水通过微小的裂缝或断裂进入建筑材料。在水、紫外线、氧气和空气中的能量的共同作用下,发生氧化反应和水解反应,导致有机高分子涂层降解,涂层吸水膨胀,干燥收缩,会产生应力。通过微观分析发现,聚合物膜经水膨胀后会出现滞后、膨胀和软化现象,降低了聚合物膜的桥接作用。然后,聚合物膜由于降解而失去附着力,导致降解、失去附着力等致命伤害。

During the continuous rainy season. The polymer film absorbs more rainwater than it releases, which enters the building materials through tiny cracks or fractures. Under the joint action of energy in water, ultraviolet, oxygen and air, oxidation reaction and hydrolysis reaction take place, resulting in degradation of organic polymer coating, water absorption expansion and drying shrinkage of coating, which will produce stress. Through the micro analysis, it is found that the hysteresis, expansion and softening of polymer membrane will occur after water expansion, which reduces the bridging effect of polymer membrane. Then, due to degradation, the polymer membrane lost adhesion, resulting in degradation, loss of adhesion and other fatal injuries.

水蒸气的蒸发引起干缩
Drying shrinkage caused by evaporation of water vapor
聚合物砂浆在潮湿环境中长期使用会引起膨胀或收缩。水的变形与水泥砂浆的含水量和干缩率有关。湿致变形时,膨胀值为收缩值的1/4。当收缩应力大于砂浆的抗拉强度时,砂浆必然会产生裂缝,随着时间的推移损伤会逐渐扩大。
Polymer mortar will expand or contract when it is used in humid environment for a long time. The deformation of water is related to the moisture content and dry shrinkage of cement mortar. In the case of wet deformation, the expansion value is 1 / 4 of the shrinkage value. When the shrinkage stress is greater than the tensile strength of the mortar, the mortar will inevitably produce cracks, and the damage will gradually expand with the passage of time.
3.固体水冻胀
3. Solid water frost heaving
它在冬天结冰。当冰的体积比水大约9%时,会产生冻胀应力,导致聚合物砂浆粘结层破坏,导致聚合物砂浆脱落。
It freezes in winter. When the volume ratio of ice to water is about 9%, the frost heave stress will be produced, which will lead to the damage of the bond layer of polymer mortar and the fall off of polymer mortar.
挤塑板
Plastic extruded board
挤塑板是一种绿色环保保温材料,具有保温性能好、强度高、耐腐蚀等特点,所以很多客户在家居装饰中可以选择挤塑板施工。
Extrusion board is a kind of green environmental protection heat preservation material, which has the characteristics of good heat preservation performance, high strength, corrosion resistance, etc., so many customers can choose Extrusion board construction in home decoration.
上面是今天的保温材料制造商为你介绍水分子的挤压塑胶板有什么影响所有的内容,我相信你将有一个收获后,在粘贴挤压板,也提醒你应该紧密挤压板缝,相邻的挤压板应该是统一的。施工时控制面板间距不得超过2m。如果你想知道多有关山东挤塑板的情况,请通过电话联系我们或关注我们的网站:http://ejointrans.com
The above is what the manufacturer of today's thermal insulation materials introduced to you about the impact of water molecular extrusion plastic plate on all the content. I believe you will have a harvest after pasting the extrusion plate, and also remind you that you should squeeze the plate seam closely, and the adjacent extrusion plates should be unified. The distance between control panels shall not exceed 2m during construction.
