轻质抹灰石膏的性能特点

来源: 日期:2022-05-09 发布人:juyehe

小编带大家了解一下轻质抹灰石膏的性能特点。

Xiaobian will take you to know the performance characteristics of Shandong light plastering gypsum.
(1)粘结力强:粉刷的和易性和流动性好,使泥浆容易渗到墙体或天花板的孔隙和接缝中,硬化后,泥浆体积略有膨胀,形成键-榫和微钩体系,加强了加气混凝土与抹灰面之间的咬合能力,增加了粘结强度,既减少了地面灰和材料损失,又增强了二者界面的粘结,避免了因干燥产生收缩应力而产生的空鼓和开裂。
(1) Strong adhesion: good workability and fluidity of painting make the slurry easy to penetrate into the pores and joints of the wall or ceiling. After hardening, the slurry volume expands slightly to form a key tenon and micro hook system, which strengthens the bite ability between the aerated concrete and the plastered surface, increases the bonding strength, reduces the loss of ground ash and materials, and enhances the bonding between the two interfaces, The hollowing and cracking caused by shrinkage stress caused by drying are avoided.
(2)表面装饰性好:抹灰后的石膏墙体密实光滑,强度高无收缩,外观优雅,无灰、无收缩、无异味、无裂缝、无返碱。
(2) Good surface decoration: the plastered gypsum wall is dense and smooth, with high strength and no shrinkage, elegant appearance, no ash, no shrinkage, no peculiar smell, no crack and no alkali return.
(3)防火性能好:遇火,抹灰石膏凝结后含有大量结晶水。在热量的作用下,结晶水被释放出来形成蒸汽,阻止了火焰的蔓延,同时在脱水过程中吸收了大量的热量,从而提高了其防火性能。
(3) Good fire resistance: in case of fire, the plastering gypsum contains a large amount of crystal water after condensation. Under the action of heat, the crystalline water is released to form steam, which prevents the spread of flame. At the same time, it absorbs a lot of heat in the dehydration process, so as to improve its fire resistance.
(4)保温性好:粉刷石膏硬化体属于多孔结构,孔隙结构分布均匀,有利于避免因导热系数与加气混凝土相差较大而出现空鼓或开裂,同时具有良好的保温效果和隔音性能。
(4) Good thermal insulation: the plastered gypsum hardened body belongs to porous structure, and the pore structure is evenly distributed, which is conducive to avoiding hollowing or cracking due to the large difference between thermal conductivity and aerated concrete. At the same time, it has good thermal insulation effect and sound insulation performance.
(5)节约工期:抹灰石膏抹灰层凝结硬化快,养护周期短,比水泥砂浆或混合砂浆可缩短工期百分之70左右。
(5) Saving construction period: the plaster layer of plastering gypsum has fast setting and hardening and short maintenance period, which can shorten the construction period by about 70% compared with cement mortar or mixed mortar.
然而,正是这些特点让人们对与腻子粉的区别感到困惑。今天,我也会带你去了解一下。
However, it is these characteristics that make people confused about the difference between putty powder and putty powder. Today, I will take you to know.
1.适用范围不同:粉刷石膏主要用于建筑中各种墙面、天花板的抹灰,不适合卫生间、厨房等经常与水接触的地方。
1. Different scope of application: plastering gypsum is mainly used for plastering various walls and ceilings in buildings, and is not suitable for toilets, kitchens and other places that are often in contact with water.
2.不同功能:刮腻子是基层处理中重要的一步,主要是除掉基层表面不平整的部分,保持墙面平整光滑。
2. Different functions: puttying is an important step in the base treatment, which is mainly to remove the uneven part of the base surface and keep the wall flat and smooth.
3.不同材料:应根据适用部位合理选择不同类型的山东抹灰石膏或根据施工需要提出具有特殊性能的抹灰石膏。石膏腻子是由巴黎白粉石膏制成的,是一种气动胶凝材料。它不应该受到潮湿或雨水的影响。严禁使用受潮或结块的石膏。
3. Different materials: different types of Shandong plastering gypsum shall be reasonably selected according to the applicable parts, or plastering gypsum with special properties shall be proposed according to the construction needs. Gypsum putty is made of Paris white gypsum. It is a pneumatic cementitious material. It should not be affected by moisture or rain. Damp or caked plaster is strictly prohibited.
