轻质抹灰石膏是代替水泥砂浆的新型、环保、经济的产品，既有水泥的强度，又比水泥健康环保、持久耐用，粘接力大、不易粉化、不开裂、不空鼓、不掉粉等优点，使用简便，节省成本。那在施工中为什么会出现空鼓、开裂、起粉现象呢，下面我们一一分解：

Lightweight plastering gypsum is a new, environmentally friendly, and economical product that replaces cement mortar. It not only has the strength of cement, but also has the advantages of being healthier, more environmentally friendly, and more durable than cement. It has great adhesion, is not easy to powder, does not crack, does not empty, and does not drop powder. It is easy to use and saves costs. Why do hollowing, cracking, and powdering occur during construction? Let's break them down one by one:

济南轻质抹灰石膏开裂情况

Cracking of Jinan Light Plaster Gypsum

（1）建筑石膏不合格未进行陈化处理、石膏可溶性杂质过多

(1) Unqualified building gypsum without aging treatment, excessive soluble impurities in gypsum

（2）添加剂不合格添加剂和石膏不匹配

(2) Additives are not qualified Additives and gypsum do not match

（3）施工人员原因施工人员不、不安要求施工

(3) Due to the lack of professionalism and safety of construction personnel, they are required to carry out construction

（4）基层材料原因基层存在吸水、开裂、粉化等

(4) The root material causes water absorption, cracking, and pulverization in the base layer

（5）施工环境原因，天气干燥炎热、风速大、春夏之交，温度高而湿度小。

(5) Due to the construction environment, the weather is dry and hot, with high wind speed and high temperature and low humidity at the turn of spring and summer.

抹灰石膏层空鼓原因

Reasons for hollowing in the plastering gypsum layer

（1）基层疏松、强度低；光滑的基层没有涂刷界面处理剂；

(1) Loose grassroots and low strength; Smooth base layer without applying interface treatment agent;

（2）基层吸水性强，施工前没有洒透水；

(2) The base layer has strong water absorption, and there is no sprinkling of water before construction;

（3）产品质量问题：纤维素醚用量小，保水能力差，抹灰石膏内聚力小，抹灰石膏与基层的湿粘结力差；建筑石膏用量小；机喷石膏中可再分散胶粉用量少。

(3) Product quality issues: low dosage of cellulose ether, poor water retention ability, low cohesion of plastering gypsum, and poor wet adhesion between plastering gypsum and base layer; Low dosage of building gypsum; The amount of redispersible rubber powder used in machine sprayed gypsum is small.

抹灰石膏层起粉原因

Reasons for powdering of plastered gypsum layer

（1）建筑石膏未能充分水化：基层吸水性强，施工前没有洒透水；施工现场气温高，风力大；施工厚度薄；

(1) Building gypsum is not fully hydrated: the base layer has strong water absorption, and no water is sprayed thoroughly before construction; The construction site has high temperatures and strong winds; Thin construction thickness;

（2）产品质量问题：纤维素醚用量小，保水能力差；抹灰石膏强度低（建筑石膏用量小、初凝时间长）；

(2) Product quality issue: Low dosage of cellulose ether and poor water retention ability; Low strength of plastering gypsum (low dosage of building gypsum and long initial setting time);

（3）已经固化的抹灰石膏、落地灰及搓抹下的抹灰石膏加水搅拌后，重新使用。

(3) The solidified plastering gypsum, floor plaster, and the plastering gypsum after rubbing are mixed with water and reused.
