What are the advantages of dry powder mortar in masonry? Polymer dry powder mortar is widely used in masonry mainly because it has unparalleled advantages in masonry. So what are these advantages specifically?

聚合物干粉砂漿在砌筑方面的優(yōu)勢(shì)有以下幾點(diǎn)：

The advantages of polymer dry powder mortar in masonry include the following:

一、具有塑性收縮、干縮率低特性，大限度保證墻體尺寸穩(wěn)定性。

1、 It has the characteristics of plastic shrinkage and low dry shrinkage rate, ensuring maximum stability of wall dimensions.

二、具有優(yōu)異的施工和易性和粘結(jié)能力。提高施工工作性，使砌體豎立向砌筑灰縫摸漿、掛漿均勻，灰縫漿料飽滿(mǎn)，并同時(shí)增加砂漿與磚體接觸面積，保證砌筑體穩(wěn)定性。

2、 Has excellent construction workability and bonding ability. Improve the construction efficiency, ensure that the mortar is evenly applied and hung in the vertical direction of the masonry, and the mortar is full. At the same time, increase the contact area between the mortar and the brick to ensure the stability of the masonry.

三、膠凝后具有剛中代韌的力學(xué)性能。提高墻體抗裂、抗?jié)B及抗應(yīng)變能力，達(dá)到墻體免受水的侵蝕和破壞的目的。

3、 After cementation, it has mechanical properties that replace toughness with rigidity. Improve the crack resistance, impermeability, and strain resistance of walls to achieve the goal of preventing water erosion and damage to the walls.

四、具有優(yōu)異的保水性，使砂漿在更佳條件下膠凝得更為密實(shí)，并可在干燥砌塊基面都能保證砂漿有效粘。

4、 It has excellent water retention properties, making the mortar more compact under better conditions and ensuring effective adhesion on dry block surfaces.

干粉砂漿是其中一種常用于水泥砂漿改性的聚合物，它是聚合物乳液經(jīng)過(guò)正確的噴霧干燥過(guò)程(以及選用適當(dāng)?shù)奶砑觿?形成的粉末狀聚合物，在混合料與水拌和后，聚合物干粉遇水變?yōu)槿橐海谒嗌皾{凝結(jié)硬化過(guò)程中可再一次脫，聚合物顆粒在其中形成聚合物體結(jié)構(gòu)，從而與聚合物乳液的作用過(guò)程相似，對(duì)水泥砂漿起到改性作用。由于聚合物干粉砂漿不像聚合物乳液那樣需要考慮乳液配制、穩(wěn)定性的問(wèn)題、小摻量就可以使砂漿達(dá)到所需性能，因而具有比乳液易于包裝、儲(chǔ)存、運(yùn)輸和供應(yīng)，抗凍和無(wú)生酶、生細(xì)菌的問(wèn)題，以及可與水泥和砂等預(yù)拌包裝制成單組分產(chǎn)品，加水既可使用的優(yōu)點(diǎn)。應(yīng)用時(shí)，預(yù)先把級(jí)配砂、水泥、聚合物干粉以及其它輔加劑混合包裝好，現(xiàn)場(chǎng)施工時(shí)只需加入一定量的水既可獲得性能較好的聚合物干粉改性水泥砂漿。現(xiàn)場(chǎng)施工時(shí)，由于只需向聚合物于粉改性的水泥砂漿中加入適量的水既可，因而減少了配料差錯(cuò)。聚合物千粉改性水泥砂漿由于所摻聚合物干粉砂漿比聚合物乳液更具有的優(yōu)勢(shì)，以及聚合物干粉改性水泥砂漿具有配制方便、性能良好等優(yōu)點(diǎn)，

Dry powder mortar is one of the polymers commonly used for cement mortar modification. It is a powdered polymer formed by the polymer lotion through the correct spray drying process (and the selection of appropriate additives). After mixing the mixture with water, the polymer dry powder becomes lotion when it meets water, and can be detached again during the setting and hardening process of cement mortar. Polymer particles form a polymer structure in it, which is similar to the action process of the polymer lotion, and plays a modifying role in cement mortar. Because polymer dry powder mortar does not need to consider the preparation and stability of lotion as polymer lotion does, and the mortar can reach the required performance with a small amount of addition, it is easier to package, store, transport and supply than lotion, and has the problems of frost resistance, enzyme free and bacteria free. It can be mixed with cement, sand and other ready mixed packaging to form a single component product, which can be used with water. When applying, mix and package graded sand, cement, polymer dry powder, and other additives in advance. During on-site construction, only a certain amount of water needs to be added to obtain polymer dry powder modified cement mortar with good performance. During on-site construction, adding an appropriate amount of water to the polymer powder modified cement mortar reduces batching errors. The polymer dry powder modified cement mortar has more advantages than the polymer lotion, and the polymer dry powder modified cement mortar has the advantages of convenient preparation and good performance,
