The effect of interfacial agents

1、用于处理混凝土、加气混凝土、灰砂砖及粉煤灰砖等表面，解决由于这些表面吸水性强或光滑引起界面不易粘接，致使抹灰层空鼓、开裂、剥落等。

1. It is used to deal with the surface of concrete, aerated concrete, lime sand brick and fly ash brick, so that the surface of the plastering layer is not easy to be bonded because of the strong or smooth surface water absorption or smooth surface, which causes the plastering layer to be empty, cracking, and exfoliating.

2、用于施工缝梁柱加固、旧基础改造等新老混凝土连接，大大增强新旧混凝土之间以及混凝土与抹灰砂浆的粘结力。

2. It is used for the connection of the new and old concrete, such as the reinforcement of the construction seam beam and the column, the old foundation, and the bond between the old and the old concrete and the concrete and the plastering mortar.

3、取代光滑混凝土表面的碱洗除油、人工凿毛等工序，可提高粘接力10倍以上。

3, the process of alkali washing, oil removing and manual chisel instead of smooth concrete surface can increase the adhesive force by more than 10 times.

4、采用界面涂敷法或配成高粘接力的砂浆，自己铺贴大块砖板，并可在旧面上粘贴新面砖。

4, we should use the interface coating method or the mortar with high viscosity to lay large bricks, and we can paste new tiles on the old ones.

5、可用于混凝土和钢筋的表面保护、防止劣化和腐蚀。有起砂或少量油污的基层科直接涂敷、抹灰处理。

5, it can be used for surface protection and prevention of deterioration and corrosion of concrete and reinforcement. A basic department with sand or a small amount of oil pollution is directly coated and plastered.

6、具有很强的渗透性，能够充分浸润进材料表面，可在潮湿基层施工，可作为油性涂料的隔潮层，与聚氨酯涂层粘接牢固。

6. It has strong permeability and can be fully infiltrated into the surface of the material. It can be constructed in the wet base and can be used as the tidal layer of the oily coating, which is firmly bonded to the polyurethane coating.

7、抗压强度高，室温固化28天后，进行抗压强度试验。达31.1Mpa，克服了因强度不高引起的开裂。

7, high compressive strength, curing at room temperature for 28 days, carry out the compressive strength test. Up to 31.1Mpa, the cracking caused by low strength is overcome.

界面剂的工作原理

The working principle of the interface agent

界面剂能填平基材墙面的孔隙，减少墙体的吸收性，保证覆面砂浆材料在更佳条件下黏结胶凝。同时界面剂担负着墙面和表面材料粘合的媒介，保证整体结合成一个永久黏合的整体。

The interface agent can fill the pores of the substrate wall, reduce the absorbency of the wall, and ensure the bonding and cementing of the mortar material under better conditions. At the same time, the interface agent is responsible for the adhesion between the wall and the surface material, so that the whole body can be combined into a permanently cohesive whole.

界面剂的类型

Type of interfacial agents

市面上常见界面剂分为干粉型和乳液型两种。

There are two kinds of interface agents on the market: dry powder and emulsion.

干粉型界面剂 ：

Dry powder interface agent:

由水泥等无机胶凝材料、填料、聚合物胶粉和相关的外加剂组成的粉状物。具有高黏结力，优秀的耐水性、耐老化性。使用时按一定比例掺水搅拌使用。

It consists of cement and other inorganic cementitious materials, fillers, polymer powder and related admixtures. It has high adhesion strength, excellent water resistance and aging resistance. When used, mixing and mixing in a certain proportion of water.
