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

（1）粘結(jié)力強(qiáng)：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(qiáng)了加氣混凝土與抹灰面之間的咬合能力，增加了粘結(jié)強(qiáng)度，既減少了地面灰和材料損失，又增強(qiáng)了二者界面的粘結(jié)，避免了因干燥產(chǎn)生收縮應(yīng)力而產(chǎn)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(shí)光滑，強(qiáng)度高無收縮，外觀優(yōu)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(jié)后含有大量結(jié)晶水。在熱量的作用下，結(jié)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(jié)構(gòu)，孔隙結(jié)構(gòu)分布均勻，有利于避免因?qū)嵯禂?shù)與加氣混凝土相差較大而出現(xiàn)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(jié)約工期：抹灰石膏抹灰層凝結(jié)硬化快，養(yǎng)護(hù)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(diǎn)讓人們對與膩?zhàn)臃鄣膮^(qū)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(wèi)生間、廚房等經(jīng)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.
