輕質抹灰石膏的性能特點

來源：http://www.wavc.cn 日期：2022-05-09 發布人：

小編帶大家了解一下輕質抹灰石膏的性能特點。

Xiaobian will take you to know the performance characteristics of Shandong light plastering gypsum.

（1）粘結力強：粉刷的和易性和流動性好，使泥漿容易滲到墻體或天花板的孔隙和接縫中，硬化后，泥漿體積略有膨脹，形成鍵-榫和微鉤體系，加強了加氣混凝土與抹灰面之間的咬合能力，增加了粘結強度，既減少了地面灰和材料損失，又增強了二者界面的粘結，避免了因干燥產生收縮應力而產生的空鼓和開裂。

(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）表面裝飾性好：抹灰后的石膏墻體密實光滑，強度高無收縮，外觀優雅，無灰、無收縮、無異味、無裂縫、無返堿。

(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，抹灰石膏凝結后含有大量結晶水。在熱量的作用下，結晶水被釋放出來形成蒸汽，阻止了火焰的蔓延，同時在脫水過程中吸收了大量的熱量，從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）保溫性好：粉刷石膏硬化體屬于多孔結構，孔隙結構分布均勻，有利于避免因導熱系數與加氣混凝土相差較大而出現空鼓或開裂，同時具有良好的保溫效果和隔音性能。

(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）節約工期：抹灰石膏抹灰層凝結硬化快，養護周期短，比水泥砂漿或混合砂漿可縮短工期百分之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，正是這些特點讓人們對與膩子粉的區別感到困惑。今天，我也會帶你去了解一下。

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.適用范圍不同：粉刷石膏主要用于建筑中各種墻面、天花板的抹灰，不適合衛生間、廚房等經常與水接觸的地方。

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：刮膩子是基層處理中重要的一步，主要是除掉基層表面不平整的部分，保持墻面平整光滑。

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：應根據適用部位合理選擇不同類型的山東抹灰石膏或根據施工需要提出具有特殊性能的抹灰石膏。石膏膩子是由巴黎白粉石膏制成的，是一種氣動膠凝材料。它不應該受到潮濕或雨水的影響。嚴禁使用受潮或結塊的石膏。

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.
