Can I open a few small holes in the floor drain pipe for secondary drainage in the bathroom?
It is not allowed to make holes in the floor drain pipe for secondary drainage.
Reason: The main reason is that the floor drain pipe in the bathroom is relatively thin. If you want to open holes for secondary drainage, it will easily cause the floor drain to become blocked, and it is not easy to repair. The floor drain pipe itself is also connected to the main sewer pipe in the bathroom, so If you want secondary drainage, you should make holes in the main sewer pipe, so that even if there is a problem, it can be easily repaired.
Will secondary drainage cause backflow?
Do not drill holes under the floor drain pipe for secondary drainage in non-sinkable bathrooms
Drill a hole in the bathroom drain outlet, then connect a water pipe and install the water pipe in In the ground binding layer, the water in the ground binding layer can be drained out.
A more complicated method is to knock off the cement on the ground to leak out the concrete and then seal it with concrete siliceous sealant. After it dries, spread the tarpaulin to achieve waterproof, anti-penetration and moisture-proof effects. Wait until it is completely dry before laying the floor tiles.
You can drill holes. In my house, I opened an opening in the sewage pipe just to test that there was no leakage. However, the level of the opening must be the lowest, otherwise the sewage will flow back in the future
Best Install a new secondary drainage pipe. Drilling holes in the toilet pipe will cause peculiar smell to come out of the secondary drainage pipe, which will be too troublesome to deal with later
Silicon waterproofing agent is polymer waterproofing Potion?
No, the advantages of silicone waterproofing agent are:
1. Excellent waterproofing and impermeability, good durability, and a service life of more than 10 years.
2. Good breathability. The hydrophobic film formed by this product is a breathable waterproof layer. Its breathable pores are smaller than water molecules and larger than water vapor. Therefore, outside rainwater cannot penetrate, but indoor moisture can be emitted.
3. Good color retention. The coating of this product is colorless and transparent, and does not affect the original color of the building when applied on the surface.
4. Convenient construction, safe and reliable. This product only needs to be painted on the surface of the building, and the construction is particularly simple.
5. Reasonable price and convenient transportation. The product has low overall cost, is non-toxic, odorless, non-flammable, non-explosive and can be transported safely.
Disadvantages of silicone waterproofing agent:
Disadvantages:
1. Leakage occurs. Many users reported that leaks still occurred in their houses after using silicone waterproofing agent, especially outside the exterior walls, where the leakage was even more serious.
2. Not fully waterproof. Silicone waterproofing agent only has good waterproofing performance for waterproofing exterior walls. Most people even think that it acts more as an anti-penetration material rather than having real waterproofing properties.
How to use waterproof densifier correctly?
1. Add it directly to the mortar or concrete mixer. The mixing time is 30 to 60 seconds longer than normal mixing, counting 2 and a half minutes or 3 minutes. If it is mixed manually, it must be mixed evenly.
2. The concrete mix proportion design is the same as that of ordinary concrete, but the cement dosage should not be less than 300kg/m3.
3. Choose fresh but not expired Portland or ordinary Portland cement. The cement has good activity and stability. The cement label is generally P.032.5 or P.042.5.
4. Sand and stone should be well graded, contain little mud and comply with relevant regulations.
5. The concrete should be vibrated and compacted without sliding vibration or strong vibration. Concrete and mortar should be compacted and compacted. Fine stone concrete should be used for the roof, and small flat plates should be vibrated and compacted. 6. Mortar or concrete should be covered with wet straw bags in time to strengthen moist curing. The general curing time is not less than 7-14 days. Concrete curing agents can also be used for curing.
What are the advantages and disadvantages of silica pigments?
Silicon pigments are the third generation of "oil painting" pigments after oil paints and acrylic paints. Silica pigments are made of green and environmentally friendly nano-silica, containing natural mineral fillers and a small amount of environmentally friendly materials. type additive. Silica pigments are non-toxic, odorless, non-irritating to the senses, and have no impact on health.
Moreover, when painting with silica paint, the brush strokes are smooth, the paint takes a moderate amount of time to dry on the screen, and can be diluted with water. It has strong coverage and is easy to cover and modify multiple times during the creation process, forming rich color levels and making it easy to create paintings with a strong three-dimensional feel.
Silica pigments are matte colors that can be partially or fully glazed with a polishing agent, making them easy to meet the artist's creative requirements. After the pigment dries, it has strong adhesion, is durable, and is not easy to peel off or fade. The color is full, thick, thick, and fresh. No matter how you blend it, it won't feel dirty or gray.
The material of silica pigments forms very durable silicate after hardening, and silicate is a mineral whose durability and weather resistance are self-evident. The siliceous paintings after the silica pigments are petrified will permanently deposit the artist's creative thoughts in the works.

What are the main uses of siliceous rock?
Uses Silical rock has many industrial uses.��. For example, flint can be used as grinding raw material and siliceous refractory material due to its high hardness; jasper can also be used as fine work stone due to its hardness, density and beautiful color.
Diatomaceous earth is widely used in various sectors such as daily chemical industry, sugar industry and water purification industry due to its strong adsorption property.
Volcanic activity can increase the silica content in the ocean and is also the main source of silicon in siliceous rocks.
Are water reducing agents and anti-cracking agents added to cement?
The water reducing agent can maintain the slump of the concrete, reduce the mixing water consumption, improve the fluidity of the concrete mixture, or reduce the cement consumption per unit to save cement. According to the water-reducing ability of water-reducing agents, they are divided into ordinary water-reducing agents (also called plasticizers, the water-reducing rate is not less than 8%), high-efficiency water-reducing agents (also called superplasticizers, the water-reducing rate is not less than 14%) and High-performance water-reducing agent (water-reducing rate not less than 25%).
Anti-crack compacting agent
Anti-crack compacting agent is a new type of multi-functional high-performance concrete admixture. After reaction, existing micro-cracks and capillary pores can be blocked, especially at the aggregate interface, effectively improving the loose structure and micro-cracks of the transition layer and improving the interface effect. At the same time, under the action of water again, crystals will always grow in the depth of the concrete, constantly closing the cracks inside the concrete, and effectively improving the impermeability performance of the concrete.
What is the difference between calcium bonding and silica cementing?
Calcium cementation: gray - light gray - off-white, easy to carve with a knife, and the carved powder is off-white. Add acid and foam vigorously.
Silice cross-linking and cement are authigenic minerals formed in intergranular pores by chemical precipitation in clastic rocks. The main cements in clastic rocks include siliceous (quartz, chalcedony and opal), carbonates and some irons. Silica occurs as cement in sandstone. It appears in various forms. There are mainly amorphous opal, cryptocrystalline chalcedony and crystalline quartz. </p
