輕質(zhì)抹灰石膏是代替水泥砂漿的新型、環(huán)保、經(jīng)濟(jì)的產(chǎn)品，既有水泥的強(qiáng)度，又比水泥健康環(huán)保、持久耐用，粘接力大、不易粉化、不開裂、不空鼓、不掉粉等優(yōu)點(diǎn)，使用簡(jiǎn)便，節(jié)省成本。那在施工中為什么會(huì)出現(xiàn)空鼓、開裂、起粉現(xiàn)象呢，下面我們一一分解：

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:

濟(jì)南輕質(zhì)抹灰石膏開裂情況

Cracking of Jinan Light Plaster Gypsum

（1）建筑石膏不合格未進(jìn)行陳化處理、石膏可溶性雜質(zhì)過多

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

（2）添加劑不合格添加劑和石膏不匹配

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

（3）施工人員原因施工人員不、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）基層材料原因基層存在吸水、開裂、粉化等

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

（5）施工環(huán)境原因，天氣干燥炎熱、風(fēng)速大、春夏之交，溫度高而濕度小。

(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.

抹灰石膏層空鼓原因

Reasons for hollowing in the plastering gypsum layer

（1）基層疏松、強(qiáng)度低；光滑的基層沒有涂刷界面處理劑；

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

（2）基層吸水性強(qiáng)，施工前沒有灑透水；

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

（3）產(chǎn)品質(zhì)量問題：纖維素醚用量小，保水能力差，抹灰石膏內(nèi)聚力小，抹灰石膏與基層的濕粘結(jié)力差；建筑石膏用量小；機(jī)噴石膏中可再分散膠粉用量少。

(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.

抹灰石膏層起粉原因

Reasons for powdering of plastered gypsum layer

（1）建筑石膏未能充分水化：基層吸水性強(qiáng)，施工前沒有灑透水；施工現(xiàn)場(chǎng)氣溫高，風(fēng)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）產(chǎn)品質(zhì)量問題：纖維素醚用量小，保水能力差；抹灰石膏強(qiáng)度低（建筑石膏用量小、初凝時(shí)間長(zhǎng)）；

(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）已經(jīng)固化的抹灰石膏、落地灰及搓抹下的抹灰石膏加水?dāng)嚢韬螅匦率褂谩?/div>
