刷石膏粉怎么避免開(kāi)裂?
How to avoid cracking when brushing gypsum powder?
抹灰也叫抹面膏,不僅和易性好,附著力強(qiáng),而且硬化快,具有防火、輕質(zhì)、保溫、隔熱等特點(diǎn),所以現(xiàn)在在建筑中被廣泛使用。但也有大師被膏藥開(kāi)裂困擾。今天,我們來(lái)談?wù)勅绾翁幚磉@類問(wèn)題。
Plastering, also known as plastering paste, not only has good workability and strong adhesion, but also hardens quickly. It has the characteristics of fire resistance, lightweight, insulation, and thermal insulation, so it is widely used in construction now. But there are also masters who are troubled by the cracking of the plaster. Today, let's talk about how to deal with such issues.
首先,我們來(lái)看看石膏開(kāi)裂的原因:
Firstly, let's take a look at the reasons for gypsum cracking:
由于混凝土吸水速度慢,抹灰層與墻面粘結(jié)時(shí)有水分,造成抹灰面空鼓開(kāi)裂。有的師傅在施工時(shí)會(huì)在加氣混凝土墻面上涂一層界面劑,從而解決粘結(jié)問(wèn)題,但還是解決不了開(kāi)裂的現(xiàn)象。
Due to the slow water absorption rate of concrete, there is moisture when the plaster layer is bonded to the wall, causing hollowing and cracking of the plaster surface. Some craftsmen apply a layer of interface agent on the aerated concrete wall during construction to solve the bonding problem, but it still cannot solve the cracking phenomenon.
而且如果抹灰前基層清理不干凈,也會(huì)造成空鼓、開(kāi)裂。另外還有一些原因,如抹灰前未澆水,每層抹灰抹灰過(guò)厚,抹灰與抹灰間隔過(guò)短,混凝土表面松散物抹灰未處理,影響抹灰抹灰與墻面的附著力,抹灰后加氣混凝土表面未清理、澆水、養(yǎng)護(hù)等。,都會(huì)造成抹灰空鼓、開(kāi)裂等問(wèn)題。
Moreover, if the base layer is not cleaned thoroughly before plastering, it can also cause hollowing and cracking. There are also some reasons, such as not watering before plastering, each layer of plastering being too thick, the interval between plastering and plastering being too short, loose materials on the concrete surface not being treated before plastering, affecting the adhesion between plastering and the wall, and the aerated concrete surface not being cleaned, watered, and cured after plastering. All of these can cause problems such as hollowing and cracking in plastering.
那么,如何避免抹灰開(kāi)裂呢?
So, how to avoid plaster cracking?
01材料使用中的注意事項(xiàng)
01 Precautions for Material Use
石膏是一種氣硬性材料,不能長(zhǎng)期與水接觸使用。配制好的抹灰漿應(yīng)在初凝前用完。如果漿料已經(jīng)初凝,不能用水?dāng)嚢瑁鸵獔?bào)廢。加水?dāng)嚢钑?huì)導(dǎo)致粉化,沒(méi)有力量,空鼓。因此,在使用中,要注意控制抹灰漿的用量。另外,抹灰時(shí)要注意不能混合其他水泥砂漿和石灰砂漿。
Gypsum is a gas hardening material that cannot be used in long-term contact with water. The prepared plastering slurry should be used up before initial setting. If the slurry has already set and cannot be stirred with water, it should be scrapped. Mixing water can cause pulverization, lack of strength, and hollowing. Therefore, in use, attention should be paid to controlling the amount of mortar used. In addition, attention should be paid to not mixing other cement mortar and lime mortar when plastering.
02施工中的注意事項(xiàng)
02 Precautions during Construction
抹灰石膏施工前,須清理浮灰、油漬、松散顆粒等。并保證抹灰石膏與基面粘結(jié)良好,防止空鼓現(xiàn)象。
Before plastering gypsum construction, floating ash, oil stains, loose particles, etc. must be cleaned. And ensure that the plaster is well bonded to the base surface to prevent hollowing.
基層吸收抹灰漿中的水分也會(huì)造成抹灰開(kāi)裂。因此,在施工過(guò)程中,要根據(jù)基層材料、施工環(huán)境、氣溫的差異,適當(dāng)均勻?yàn)⑺WC基層濕度達(dá)到施工要求后,再進(jìn)行抹灰。抹灰時(shí),應(yīng)保證墻面基層無(wú)清水。
The absorption of moisture in the plaster slurry by the base layer can also cause cracking of the plaster. Therefore, during the construction process, it is necessary to sprinkle water evenly according to the differences in base materials, construction environment, and temperature to ensure that the base humidity meets the construction requirements before plastering. When plastering, it should be ensured that there is no clear water on the base layer of the wall.
另外,要注意抹灰石膏的施工溫度,根據(jù)溫度配制抹灰石膏漿時(shí)要注意粉水比。
In addition, attention should be paid to the construction temperature of plastering gypsum, and the powder water ratio should be taken into account when preparing plastering gypsum slurry according to the temperature.
