Cement-based penetrating crystalline waterproof coating is a powdery mixture made of Portland cement, silica sand and active chemical substances. It is the world's most advanced rigid waterproof material.

Features

1, suitable for construction on the wet base surface, but also in the case of water seepage.

2, long-term impermeability and tolerance of strong water pressure, is an inorganic material does not exist aging problems, and concrete life.

3, with superior permeability, infiltration of crystals inside the concrete, not easily destroyed, with extraordinary self-repair ability, can repair cracks less than 0.4mm.

4, to prevent the freeze-thaw cycle, inhibition of alkali aggregate reaction, to prevent chemical corrosion damage to the concrete structure, to protect the steel but no effect on the expansion of the concrete expansion.

Application area

The product is suitable for the waterproofing and protection of concrete structures of underground engineering, subway and culverts, pools, and water conservancy projects in industrial and civil buildings.

Instructions

A bag of 25 kg Langkachi powder is slowly poured into clean cold water (surface treatment: 5.5 L water; brushing method: 10 L water) that is being stirred with a power stirrer, and stirred until it is uniform and free from particles. Allow the slurry to stand for 5 minutes and stir it again until the slurry is ready for use. Cross over at least two coats, and when the previous coat has cured to produce sufficient strength, the next layer can be applied. The adjusted slurry was used up within 1 hour. Coatings for outdoor construction in summer should be sprinkled with water for maintenance after 6 hours. General maintenance is 3 to 5 times per day. Conditions should be covered with wet geotextiles or sacks, bags, etc. for conservation. Can also be used high-pressure spray construction.

Precautions

1, in strict accordance with the provisions of the proportion of water, must not be arbitrarily added, otherwise it will cause the coating from the powder, low strength and other consequences.

2, must be in the wet base surface construction, but there can be no clear water.

3, the construction of the ambient temperature: 5 ~ 35 °C.

4, the construction of the summer should avoid exposure. When frost is frozen in winter, construction is prohibited and anti-freezing measures have to be taken.

5, 24 hours after the completion of the construction should be sprinkled water conservation 2 to 3 days.

6, after tearing open the package should be used up within a short period of time, should not be stored for a long time.

7. The water storage test or tiling should be carried out after the coating has dried for 72 hours, and the low temperature period in winter should be appropriately extended.

8, if you need to paste the tiles on the waterproof coating, it is recommended to use tile adhesive or low-grade cement mortar paste.

Reference dosage

For waterproofing projects, it usually takes about 2 to 2.5 kg per square meter (brushing twice).

Health and safety

This product contains cement ingredients. If the product contacts the skin, flush with water. If exposed to the eyes, rinse immediately with plenty of clean water and seek medical attention. Avoid inhalation of dry powder. Wear suitable personal protective equipment such as gloves, goggles, dust masks, etc. when necessary.

Steel Bend

Steel bends and steel elbows are both very common pipe fittings which are used to change the flowing direction in a piping systems. In addition to pipe fittings for connecting , elbow pipe also refers to a processing method. It is to Bend the straight pipe through the processing method to achieve the purpose of changing the circulation direction of the pipeline. The manufacturing process and the finished product are called pipe bend.

In order to ensure that the wall thickness of the bending part is no less than that of the straight pipe part, the minimum radius of the pipe bending should be 3D( the D means nominal diameter of this bend). The specific size depends on the operating conditions. That is to say, radius is not restricted as long as it exceeds 3D, which can be 3D or 3.2D, even 4D, 5D, 6D and 8D are also acceptable. In addition, the angle of the bend can be in any degree, some times there are also custom-designed bends which are 22.5 °, 45 °, 90 °, 135 °, 180 °, 270 ° and so on.
