Where is the bathroom waterproof?
Bathroom waterproofing is the key waterproof location, frequent contact with running water, and drain pipe, floor drain, yin and yang angles. To make the bathroom waterproof, you must handle these details to ensure the waterproof quality.
1, painted waterproof layer
The bathroom is the key location for waterproofing the home. It must be waterproof when decorating. Take the cement-based waterproof coating as an example. Leibang has a general-purpose GS waterproof coating and a flexible JS waterproof coating, and the coating is painted twice. Vertically intersecting front and rear, the thickness of the single layer is 0.8mm to 1mm, and the thickness of the two layers is not more than 2mm.
2. Joints between the yin and yang angles, the upper and lower water pipes and the ground
Leakage occurs mostly in the roots, floor drains, sanitary wares, and yin and yang corners that pass through the floor. The reason is that the roots, floor drains, etc. are loose, not firmly bonded, the coating is not tight, or the waterproof layer is partially damaged, and the parts are overlapped. The length is not enough. These corners are the most prone to leakage. Pay attention to the details of the construction, waterproof coating must be painted in place. When pipes, floor drains, etc. pass through the floor, the waterproof layer around the holes must be carefully constructed. The upper and lower pipes must be made of cement roots. Apply 10-20 cm of polyurethane waterproof coating from the ground, and then make polyurethane waterproof layer on the ground. With the original waterproof layer, a composite waterproof layer is formed to enhance the waterproof performance.
3, sewage outlets and floor drains
The floor of the kitchen and toilet must be sloping to the ground to make the drainage smooth and not accumulating water. The original drainage and sewer pipes and floor drains should be avoided as much as possible.
4, the wall of the buried water pipe
When burying the water pipe in the wall, a groove larger than the pipe diameter should be made, the ash in the groove should be smooth, and then the polymer cement-based waterproof paint should be painted in the groove for waterproof treatment.
5. Walls adjacent to the bathing facilities
When the wash basin is used, the water will splash on the wet wall. If there is no protection from the waterproof layer, the wall will be easy to be wet. If the water vapor accumulates for a long time, it will erode the wall and even penetrate the wall. Therefore, before laying the wall tile, it must be Do a good job of waterproofing the wall surface. The wall of the wash basin should be at least 30cm high. The wall facing the shower should be at least 1.8m high. It is best to waterproof the whole wall, and the wall adjacent to the bathtub. The height of the waterproof coating should also be higher than the upper edge of the bathtub.
Peristaltic Metering Pump Characteristic
1. Clean and pollution-free: the fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
