粉刷石膏粉的介紹以及特性

來源：http://www.wavc.cn 日期：2023-03-11 發布人：

粉刷石膏是以石膏為基料，輔以抹灰性能良好的附加材料及添加劑等配制而成的。經與水拌合水化生成二水石膏晶體和少量的硫鋁酸鹽，這些晶體相互交叉連接，形成網絡結構，使粉刷石膏漿體失去流動性而凝結，隨著水化的深入，凝結后水化產物繼續生成，晶體也逐漸變大，網絡結構在短時間內密實，從而產生較高粘結強度及抗折與抗壓強度。待粉刷石膏硬化體內的水分通過表面蒸發，和墻體吸收完全排除后，具備很高的強度。

Plastering gypsum is prepared with gypsum as the base material, supplemented by additional materials and additives with good plastering performance. After hydration with water, dihydrate gypsum crystals and a small amount of sulphoaluminate are generated. These crystals are interconnected to form a network structure, which makes the plaster paste lose its fluidity and coagulate. With the deepening of hydration, the hydration products continue to be generated after coagulation, and the crystals gradually become larger. The network structure is dense in a short time, resulting in higher bond strength, flexural strength and compressive strength. After the water in the hardened body of the plaster evaporates through the surface and is completely removed from the wall, it has high strength.

因此它具有如下特性，下面濟南石膏粉廠家為您整理：

Therefore, it has the following characteristics. Jinan gypsum powder manufacturer will sort it out for you:

1.具有質地細膩、光滑、不掉灰、防火性能，并有優良的防水性能的綠色產品。

1. It is a green product with fine texture, smooth, dust-free, fireproof performance and excellent waterproof performance.

2.采用混合相型配方，級配合理、工藝先進、技術保障、質量穩定。

2. Adopt mixed phase formula, with reasonable gradation, advanced technology, technical guarantee and stable quality.

3.具有呼吸功能，能調節室內空氣濕度，無放射性，抗菌無毒，屬綠色環保建筑材料。

3. It has respiratory function, can adjust indoor air humidity, is non-radioactive, antibacterial and non-toxic, and is a green environmental protection building material.

4.抹灰層與基層粘結牢固，不空鼓、不脫落，水化微膨脹，抑制開裂，凝結硬化快，水化過程中強度連續增長，易于手工或機械抹灰，具有施工方便、效率高，落地灰少等優點。它的粘結強度一般波動于0.5—1.5Mpa之間。

4. The plastering layer is firmly bonded with the base layer, without hollowing or falling off, hydration micro-expansion, cracking inhibition, rapid solidification and hardening, continuous strength growth during hydration, easy to be plastered manually or mechanically, with the advantages of convenient construction, high efficiency, and less floor plaster. Its bond strength generally fluctuates between 0.5-1.5Mpa.

5.具有較高的強度性能，粉刷石膏隨著氣溫的變化和通風條件變化，水份會在較短的時間內排除而凝結硬化，因此具有很好的早期強度。一般自然條件下，7d搞壓強度可達到8Mpa以上，而且后期強度也會隨著游離水的不斷排除，而增加后期強度。

5. It has high strength performance. With the change of air temperature and ventilation conditions, the water in the plastering gypsum will be removed in a short time and solidified, so it has good early strength. Under general natural conditions, the 7d compressive strength can reach more than 8Mpa, and the later strength will increase with the continuous removal of free water.

實驗表明，面層粉刷石膏的水膏比0.4：1的抗壓強度為10Mpa，底層型粉刷石膏的配合比為，水：粉刷石膏：粗砂的重量比為0.5:0.6:1,其抗壓強度可達7—8.5Mpa。粉刷石膏若與水泥混合使用強度會更高，而且施工性能良好。

The test shows that the compressive strength of the surface plaster with the water-gypsum ratio of 0.4:1 is 10Mpa, the mix ratio of the bottom plaster is, the weight ratio of water: plaster: coarse sand is 0.5:0.6:1, and the compressive strength can reach 7-8.5Mpa. If plastered gypsum is mixed with cement, the strength will be higher, and the construction performance is good.

6.具有隔熱保溫和隔音性能，粉刷石膏在凝結過程中隨著水份的排除，內部產生微小的孔隙，其孔隙結構細微均勻。因此導熱系數小能衰減聲壓，又可防止聲能透射，加上石膏本身的熱惰性高，故墻體散熱慢，起到了隔熱、隔音的作用。

6. It has thermal insulation and sound insulation properties. With the removal of water in the setting process of plastering gypsum, tiny pores are produced inside, and its pore structure is fine and uniform. Therefore, the small thermal conductivity can attenuate the sound pressure and prevent the transmission of sound energy. In addition to the high thermal inertia of gypsum itself, the heat dissipation of the wall is slow, which plays the role of heat insulation and sound insulation.

有針對性地解決了不同基層的抹灰問題，又能保持原有抹灰習慣的高性能傻瓜型抹灰材料，裝飾效果好。更多相關內容就來我們網站http://www.wavc.cn咨詢！
