Plaster gypsum is a kind of high-efficiency and energy-saving plastering material for building interior walls and roofs, which is made of gypsum as the main cementing material, sand, certain admixtures and special compound additives. It mainly replaces plastering materials such as cement and lime mortar, and is suitable for all kinds of walls. Compared with traditional materials, plastering gypsum has unique advantages:

　　1、粘接力強(qiáng)：

　　1. Strong adhesion:

　　粉刷石膏與各種墻體基材（粘土磚、水泥砌塊、加氣混凝土、粉煤灰磚、石膏砌塊、現(xiàn)澆混凝土、頂棚等）都能很好地粘結(jié)，抹灰時(shí)不用刷任何界面劑，直接抹灰，一次成活，抹灰墻面不會(huì)出現(xiàn)空鼓、開(kāi)裂現(xiàn)象。

　　Plaster gypsum and all kinds of wall base materials (clay brick, cement block, aerated concrete, fly ash brick, gypsum block, cast-in-situ concrete, roof, etc.) can be well bonded, plastering without any interface agent, plastering directly, once survived, plastering wall surface will not appear empty drum, cracking phenomenon.

　　2、表面裝飾性：

　　2. Surface decoration:

　　粉刷石膏墻面細(xì)膩光滑而不起灰，強(qiáng)度高、不收縮，外觀(guān)典雅，無(wú)氣味，不返堿，無(wú)裂紋。

　　Painting gypsum wall surface is fine and smooth without ash, high strength, no shrinkage, elegant appearance, no odor, no alkali, no cracks.

　　3、防火性能：

　　3. Fire protection performance:

　　當(dāng)粉刷石膏抹面厚度為20mm時(shí)，耐火極限可達(dá)到2小時(shí)以上。

　　When the thickness of plastering plaster is 20 mm, the fire resistance limit can reach more than 2 hours.

　　4、呼吸功能：

　　4. Respiratory function:

　　粉刷石膏硬化過(guò)程中，形成無(wú)數(shù)個(gè)微小的蜂窩狀呼吸孔，當(dāng)室內(nèi)環(huán)境濕度較大時(shí)，呼吸孔自動(dòng)吸濕；在相反條件下，能自動(dòng)釋放儲(chǔ)備水分。

　　In the process of plastering gypsum hardening, innumerable tiny honeycomb breathing holes are formed. When the indoor environment humidity is high, the breathing holes absorb moisture automatically. Under the opposite conditions, the reserve moisture can be released automatically.

　　5、保溫隔熱：

　　5. Insulation and insulation:

　　石膏制品導(dǎo)熱系數(shù)小，約為水泥砼制品導(dǎo)熱系數(shù)25%，粘土磚的30%。

　　The thermal conductivity of gypsum products is small, which is about 25% of that of cement concrete products and 30% of that of clay bricks.

　　6、節(jié)省工期、節(jié)約成本：

　　6. Saving time and cost:

　　粉刷石膏抹灰層凝結(jié)硬化快，養(yǎng)護(hù)周期短，整個(gè)硬化及強(qiáng)度達(dá)標(biāo)過(guò)程5-7天全部完成，可大大提高工作效率，加快后續(xù)工程進(jìn)度，與水泥混合砂漿相比可以提前工期1-2月的時(shí)間。

　　The plastering gypsum plaster layer has the advantages of fast setting and hardening, short curing period, complete hardening and strength up to standard in 5-7 days, which can greatly improve work efficiency and speed up the progress of follow-up projects. Compared with cement mortar, the plastering gypsum plastering layer can advance the construction period by 1-2 months.

　　7、施工方便：

　　7. Convenient construction:

　　抹灰施工中具有易抹、易刮平、易修補(bǔ)，勞動(dòng)強(qiáng)度低，材料消耗少，冬季施工不受氣溫降低至接近0℃時(shí)影響等特點(diǎn)。

　　The plastering construction has the characteristics of easy plastering, easy scraping, easy repairing, low labor intensity, less material consumption, and winter construction is not affected by the temperature drop to nearly 0 C.

　　8、隔音性能：

　　8. Sound insulation performance:

　　粉刷石膏在凝結(jié)過(guò)程中，內(nèi)部產(chǎn)生微小的孔隙，因此能衰減聲壓，又可防止聲能透射，具有良好的隔音性能。

　　During the condensation process of plastering gypsum, there are tiny holes in the interior, so it can attenuate the sound pressure and prevent the transmission of sound energy, so it has good sound insulation performance.

　　9、衛(wèi)生健康性：

　　9. Health:

　　石膏具有消毒殺毒作用，在石膏材料裝修房間里，細(xì)菌難以生存和傳播。用粉刷石膏的房間尤其適用于嬰幼兒和老年人居住。

　　Gypsum has the function of disinfection and disinfection. It is difficult for bacteria to survive and spread in gypsum material decorated rooms. The rooms painted with gypsum are especially suitable for infants and the elderly.
