How to avoid light gypsum hollowing? As a new type of wall plastering material, light plastering gypsum summarizes its causes and prevention methods from the aspects of wall pouring, whole wall and local hollowing. Let's follow the plaster manufacturer to learn about it! 1、 The main reasons for the hollowing of light plastering gypsum are as follows:

1、墻體未進行界面處理，墻面有灰塵、油漬等雜物，影響輕質(zhì)抹灰石膏的粘結，導致空鼓。因此，輕質(zhì)抹灰石膏施工前，需要先對墻面進行界面處理

1. The wall is not subject to interface treatment, and there are dust, oil stains and other sundries on the wall, which affect the bonding of light plastering gypsum and lead to hollowing. Therefore, before the construction of light plastering gypsum, the interface of the wall needs to be treated first

2、輕質(zhì)抹灰石膏粘結性差，施工后出現(xiàn)空鼓現(xiàn)象。因此，在選購輕質(zhì)抹灰石膏時，一定要選用合格的材料

2. The light plastering gypsum has poor adhesion and hollowing after construction. Therefore, when purchasing light plastering gypsum, we must select qualified materials

3、輕質(zhì)抹灰石膏與水性界面劑不匹配，造成空鼓。在這種情況下，我們需要購買與輕質(zhì)石膏相同的界面劑材料。

3. The light plastering gypsum does not match with the water-based interface agent, resulting in hollowing. In this case, we need to buy the same interfacial agent material as light gypsum.

二、輕抹灰石膏墻體空鼓的主要原因有：

2、 The main reasons for hollowing of light plastered gypsum wall are:

1、抹灰石膏附著力差，自身產(chǎn)品質(zhì)量存在問題

1. The adhesion of plastering gypsum is poor, and there are problems in its own product quality

2、抹灰凝結時間過長，失去粘性，自然風干，造成空鼓。這兩種情況都是由于輕質(zhì)抹灰石膏本身的質(zhì)量問題造成的，因此預防的方法是選用合格的輕質(zhì)抹灰石膏材料。

2. The plastering setting time is too long, loses its viscosity, and is dried naturally, resulting in hollowing. Both cases are caused by the quality problems of light plastering gypsum itself. Therefore, the prevention method is to select qualified light plastering gypsum materials.

3、輔助保溫，營造更舒服的生活環(huán)境；輕質(zhì)抹灰石膏是一種阻燃材料。在火災情況下，許多結晶水在熱效應下從水合石膏的硬石膏基質(zhì)中釋放出來，產(chǎn)生蒸汽，從而防止火災擴散。此外，它在整個干燥過程中消化和吸收大量熱量，從而提高防火性能。

3. Auxiliary thermal insulation to create a more comfortable living environment; Light plastering gypsum is a kind of flame retardant material. In case of fire, many crystalline water is released from the anhydrite matrix of hydrated gypsum under thermal effect to produce steam, so as to prevent the spread of fire. In addition, it digests and absorbs a large amount of heat during the whole drying process, so as to improve the fire resistance.

用輕質(zhì)石膏代替水泥砂漿，不僅具有水泥的強度，而且比水泥更健康耐用，是一種新型、環(huán)保、經(jīng)濟的推廣。具有附著力大、不易粉碎、不開裂、不空鼓、不掉粉等優(yōu)點。使用方便，節(jié)約成本。抹灰石膏是建筑石膏的結合劑。

Using light gypsum instead of cement mortar not only has the strength of cement, but also is healthier and more durable than cement. It is a new, environmental protection and economic promotion. It has the advantages of high adhesion, not easy to crush, not crack, not empty drum, not falling powder and so on. Easy to use and cost saving. Plastering gypsum is the binder of building gypsum.
