水泥：好先用425＃普通硅盐水泥；水：一般饮用自来水；
砂：颗料紧硬，表面粗糙、中砂为宜（粒径为1~2mm）含泥量不大于3%。
2、砂浆的施工方法：
①基层处理：施工面要求坚实，并进行凿毛后用水冲洗干净。基面如有裂缝、缺棱、掉角、凹凸不平应用水泥砂浆进行修补。
②抹结合层：在某层上抹2~3mm的水泥素浆膏，使基层与水泥素浆膏牢固地结合在一起，待其达到初凝时再进行下道工序。
③抹砂浆：分两层施工，每层约10mm，底层初凝时，压实并用木抹成麻面，再做面层；当面层初凝时赶光压实，搞成麻面待做保护层。
④做保护层：抹不掺剂的砂浆2~3mm厚。
⑤养护：露天按正常养护，一般应不少于7天（正常为14天），如养护在高温情况下，应做好遮阴措施，避免水份过早蒸发。
3、混凝土的施工方法：
①配制硅水：剂：水=1：12~13(重量比)
②施工方法：与普通混凝土施工方法相同。
六、产品包装：

包装分为25kg、50kg/桶。

First, product introduction:


Silicone nano waterproofing agent is based on sodium methylsilanol. It is a small molecule water-soluble mixture, easy to be weak acid decomposition, in the air carbon dioxide and water, can produce methylsiloxane, water-insoluble methyl silicone ether (waterproof film), is a hydrophobic substance. When it is mixed into cement mortar or concrete, the cracks in the pores of cement mortar or concrete can be blocked, the compactness can be enhanced and the impermeability can be improved. At the same time, the air and water vapor in the material can be permeated through the waterproof membrane to keep the permeability of the engineering material. This material not only has excellent waterproof and impervious effect but also has air permeability. It has been affirmed by users in many waterproof projects.


Two, product advantages:


1, non-toxic, tasteless, non volatile, non corrosive, non flammable, pollute the environment, easy to store.


2. It has good corrosion resistance, weatherability, strong permeability, waterproof and breathability.


3. It is easy to construct, low in cost, reliable in performance and wide in scope of application.


Three. Scope of application:


1. Mix the waterproofing agent and water in a certain proportion to make silicon water and then prepare waterproof mortar.


2. Waterproof of various parts of the building's exterior walls and underground construction works, such as internal walls, retaining walls, etc.


3, waterworks and water storage buildings, such as edible pools, water towers and other waterworks.


4, roofing, toilet, bath, tunnel, civil air defense works and other waterproofing works.

Cement: it is best to use 425 ordinary silicate cement; water: General tap water;


Sand: hard material, rough surface, medium sand is suitable (particle size is 1~2mm), clay content is not greater than 3%.


2, waterproof mortar construction method:


First, grass-roots treatment: the construction surface is solid, and rinse well after water is cut. If the base surface has cracks, edges, corners, and uneven, cement mortar is used to repair.


(2) bonding layer: plaster 2-3 mm cement paste on a certain layer, so that the base and cement paste firmly together, until it reaches the initial setting before the next process.


(3) plastering waterproof mortar: two layers of construction, each layer of about 10 mm, the bottom of the initial setting, compaction and wood into a hemp surface, and then do the surface layer; when the surface of the first solidification of light compaction, make hemp surface to be a protective layer.


4. Make protective coating: mortar 2~3mm without water repellent.


_Maintenance: Open air should be maintained normally for no less than 7 days (normal for 14 days). If maintained in high temperature, shading measures should be taken to avoid premature evaporation of water.


3, waterproof concrete construction methods:


Preparation of silicon water: water repellent: water =1:12~13 (weight ratio)


2. Construction method: same as ordinary concrete construction method.


Six, product packaging:


The packaging is divided into 25kg and 50kg/ barrels.
