It is not recommended to stick tiles or apply putty with strong rigidity on it.

　　3、輕質抹灰石膏：

　　3. Lightweight plastering gypsum:

　　作為一種新型內墻抹灰材料，輕質抹灰石膏將完全代替傳統水泥砂漿，這從發達國家輕質抹灰石膏在室內墻面找平中占主導地位可窺見一斑。在美國、德國、法國、西班牙、土耳其，輕質抹灰石膏占90%份額，水泥砂漿已不到10%；在英國，輕質內墻抹灰石膏占椐96%份額。

　　As a new type of interior wall plastering material, lightweight plastering gypsum will completely replace traditional cement mortar, which can be seen from the dominant position of lightweight plastering gypsum in indoor wall leveling in developed countries. In the United States, Germany, France, Spain and Türkiye, light plaster gypsum accounts for 90% of the total, while cement mortar accounts for less than 10%; In the UK, lightweight interior plastering gypsum accounts for 96% of the market share.

　　適用范圍：除衛生間，廚房之外、適用于各種磚墻、混凝土墻、砌塊墻、水泥墻（板）、現澆混凝土墻、裝配式內隔墻板的內墻面抹灰找平及修補。

　　Scope of application: In addition to bathrooms and kitchens, it is suitable for plastering, leveling, and repairing various types of brick walls, concrete walls, block walls, cement walls (slabs), cast-in-place concrete walls, and prefabricated interior partition walls.

　　輕質抹灰石膏作為一種新型內墻抹灰石膏，除了上述環保、保溫特點外，輕質抹灰石膏還具有以下特點：

　　Lightweight plastering gypsum, as a new type of interior wall plastering gypsum, has the following characteristics in addition to the environmental protection and insulation features mentioned above:

　　高效：輕質抹灰石膏作業面針對下一道膩子工序的間隔周期是很短的，效率遠高于傳統砂漿抹灰。從而為業主和總包節省相當可觀的時間和費用。

　　Efficient: The interval between the lightweight plastering gypsum work surface and the next putty process is very short, and the efficiency is much higher than traditional mortar plastering. This saves considerable time and costs for both the owners and the general contractor.

　　重量輕、施工面積大、能耗低：同重量下，輕質抹灰石膏施工面積是普通抹灰石膏的1.6-1.8倍, 是傳統商品水泥抹灰砂漿粉刷面積的2倍多。可以較大地節省用量、運力及費用和生產能耗，從而降低總體造價。同時還可以降低建筑負載總量。

　　Lightweight, large construction area, and low energy consumption: Under the same weight, the construction area of lightweight plastering gypsum is 1.6-1.8 times that of ordinary plastering gypsum, and more than twice that of traditional commodity cement plastering mortar. It can significantly save on usage, transportation capacity, costs, and production energy consumption, thereby reducing overall costs. At the same time, it can also reduce the total load of the building.

　　施工方便：輕質抹灰石膏既可以手工抹灰施工，且工人施工相對普通抹灰石膏更省力，效率更高。也可以通過機器噴涂的方式進行（效率提高約1倍），同時也是沖筋工藝的首選材料。輕質抹灰石膏具有良好的抗裂性，適合墻面進行薄抹灰，不同的施工場所對它的厚度有不同的要求。墻體施工厚度為5~20mm，最小厚度不小于5mm，頂面抹灰總厚度應小于10mm。一般來說在家裝工地施工中，它的厚度大多在10mm左右;有的工地施工則是做15mm。

　　Convenient construction: Lightweight plastering gypsum can be manually applied, and workers are more labor-saving and efficient in construction compared to ordinary plastering gypsum. It can also be done by machine spraying (increasing efficiency by about 1 times), and it is also the preferred material for the punching process. Lightweight plastering gypsum has good crack resistance and is suitable for thin plastering on walls. Different construction sites have different requirements for its thickness. The thickness of wall construction is 5-20mm, with a minimum thickness of not less than 5mm, and the total thickness of top plastering should be less than 10mm. Generally speaking, in home decoration construction sites, its thickness is mostly around 10mm; Some construction sites require a thickness of 15mm.

　　上墻效果好：輕質抹灰石膏材料構成都比較細膩，上墻效果好。

　　Good wall effect: The lightweight plastering gypsum material composition is relatively delicate, and the wall effect is good.

　　抹灰石膏和輕質抹灰石膏，

　　Plastering gypsum and lightweight plastering gypsum,

　　功能相似，那如何選擇呢？

　　How to choose if the functions are similar?

　　我們通常所說的抹灰石膏，一般是重質石膏，而輕質抹灰石膏通常稱之為輕抹。

　　The plastering gypsum we usually refer to is usually heavy gypsum, while lightweight plastering gypsum is usually called light plaster.

　　骨料不同

　　Different aggregates

　　重質石膏和輕質石膏兩者骨料不一樣，重質石膏骨料是沙子，輕質石膏是玻化微珠。玻化微珠作輕質填充骨料有絕熱、防火、吸音等優點。在建材行業中，用玻化微珠作為輕質骨料，可提高砂漿的和易流動性和自抗強度，減少材性收縮率，提高產品綜合性能，降低綜合生產成本。同時玻化微珠相較沙子還可以因為表面玻化形成一定的顆粒強度，而具有耐老化耐候性強和優異的絕熱、防火、吸音等性能。

　　Heavy gypsum and light gypsum have different aggregates. Heavy gypsum aggregates are sand, while light gypsum aggregates are vitrified microbeads. Vitrified microbeads as lightweight filling aggregates have advantages such as thermal insulation, fire resistance, and sound absorption. In the building materials industry, using vitrified microbeads as lightweight aggregates can improve the workability and self strength of mortar, reduce material shrinkage, enhance product performance, and reduce overall production costs. At the same time, compared to sand, vitrified microbeads can also form a certain particle strength due to surface vitrification, and have strong aging and weather resistance, as well as excellent insulation, fire resistance, sound absorption and other properties.

　　石膏含量不同

　　Gypsum content varies

　　輕質抹灰石膏要求石膏粉含量≥75%，重質抹灰石膏要求石膏粉含量≥35%。

　　Lightweight plastering gypsum requires a gypsum powder content of ≥ 75%, while heavy plastering gypsum requires a gypsum powder content of ≥ 35%.

　　技術性能不同

　　Different technical performance

　　1、密度不同；輕質抹灰石膏密度≤1000kg/m3，重質抹灰石膏密度＞1000kg/m3。

　　1. Different densities; The density of lightweight plastering gypsum is ≤ 1000kg/m3, and the density of heavy plastering gypsum is>1000kg/m3.

　　2、保水率（%）；輕質抹灰石膏保水率≥ 60%，重質抹灰石膏保水率≥ 75%。

　　2. Water retention rate (%); The water retention rate of lightweight plastering gypsum is ≥ 60%, and the water retention rate of heavy-duty plastering gypsum is ≥ 75%.

　　3、拉伸粘結強度；輕質抹灰石膏拉伸粘結強度≥0.3Mpa，重質抹灰石膏拉伸粘結強度≥0.4Mpa。

　　3. Tensile bonding strength; The tensile bonding strength of lightweight plastering gypsum is ≥ 0.3Mpa, and the tensile bonding strength of heavy plastering gypsum is ≥ 0.4Mpa.

　　4、抗壓強度；輕質抹灰石膏抗壓強度≥1.5Mpa，重質抹灰石膏抗壓強度≥4.0Mpa。

　　4. Compressive strength; The compressive strength of lightweight plastering gypsum is ≥ 1.5Mpa, and the compressive strength of heavy plastering gypsum is ≥ 4.0Mpa.

　　5、抗折強度；輕質抹灰石膏抗折強度≥1.0Mpa，重質抹灰石膏抗折強度≥2.0Mpa。

　　5. Flexural strength; The flexural strength of lightweight plastering gypsum is ≥ 1.0Mpa, and the flexural strength of heavy-duty plastering gypsum is ≥ 2.0Mpa.

　　輕質抹灰石膏具有容重小，施工便捷，好運輸，遇水不化，成本低，保溫性能優良，強度適中，能夠機械噴涂等種種特點，是淘汰重質粉刷石膏后的又一升級換代產品。給開發商和施工單位帶來了福音，給住戶帶來了更加舒適的環境。輕質抹灰石膏與市場上相比，每噸可出面積130㎡/公分，是重質粉刷石膏的3倍，大大提高了施工的效率和運輸成本。

　　Lightweight plastering gypsum has various characteristics such as low bulk density, convenient construction, easy transportation, non hydration when in contact with water, low cost, excellent insulation performance, moderate strength, and the ability to be mechanically sprayed. It is another upgraded product after eliminating heavy plastering gypsum. Bringing good news to developers and construction units, and providing residents with a more comfortable environment. Compared with the market, lightweight plastering gypsum can produce an area of 130 square meters per ton, which is three times that of heavy plastering gypsum, greatly improving construction efficiency and transportation costs.

　　重質粉刷石膏主要以沙子為主，輕質抹灰石膏主要以石膏為主，這是從重與輕當中的直觀理解，在施工厚度方面重質石膏單批次0.6cm左右，施工過厚容易出現下墜，開裂等情況，輕質石膏就不一樣了，單次可以達到1cm左右，同時輕質石膏比較粘稠不會出現空鼓、下墜等情況。

　　Heavy plastering gypsum is mainly composed of sand, while lightweight plastering gypsum is mainly composed of gypsum. This is an intuitive understanding of the difference between heavy and light. In terms of construction thickness, heavy gypsum can be used in a single batch of about 0.6cm. If the construction thickness is too thick, it is easy to fall or crack, while lightweight gypsum is different. A single batch can reach about 1cm, and lightweight gypsum is relatively viscous and will not cause hollowing or falling.
