Home decoration waterway reform knowledge
First, the common types of waterway reforms and the reasons for water changes are based on the population and water use habits of each family to create a personalized water environment. There are more tricks and each one is different. Commonly used methods: 1. Change the pipe to a pipe (to spend a lot of money on a wall, bury it in the water pipe, bury it in the water pipe, and in order to look good, it's better to repair it.) Remember to seal it before you: 1) Do it well Waterproof, 2) The pipeline should be tested without pressure, 3) The joints of ia pipe should not be left in the wall); 2. The cast iron pipe should be plastic pipe (aluminum plastic pipe or PP-R pipe), or simply replaced Brass tube (It is said that the copper ions washed down are beneficial to health. As the traditional cast iron pipes have defects such as easily rusted pipes, they have not been recommended; PPR or copper pipes are currently recommended for use in water pipe pipes; 3. Hot water pipes are added. For households using gas water heaters, lead the pipelines to the bathroom, use electric water heaters to separate the water heaters in the bathroom and kitchen, and then connect the hot water pipes respectively.Note: The PPR pipes are divided into hot and cold water pipes, and the corresponding wall and pressure resistance are Different, hot water pipe pipe wall thickness (3.4mm, 2.0MPa, 4mm pipe diameter 20mm) 4. Change the position of the valve water meter (the total water pipe valve is changed to a low position, and even wrap it up, this maintenance and operation will bring Certain hidden dangers, recommend: The total water valve Put in a better position for open work, such as on the countertop, the pipeline behind the valve will be treated as a low position; washing machine off-site or faucet will guide the balcony to wash the mop and watering in the future; It can save space, but it is difficult to overhaul and check after putting the cabinets. The correct way is: rely on one end of the cabinet and install the lower wall of the vertical wall.) 5. Add purification equipment. Reserve the branch interface of the purification equipment and wait for the renovation. After the cabinets are in place, water purifiers and water softener manufacturers are required to install water purification equipment, which is generally installed in the space below the sink, so the kitchen cabinet where the sinks are located should be sufficiently partitioned, such as 80 cm. 6. Setting up the water pipeline With the rise in the price of water, the use of recycled water in the community is already a trend, and there is already a corresponding pipeline in the bathroom of the 37th house. The space is ready to be reconstructed in the future.7, change the heating pipe, move the radiator to the place where the furniture is conveniently placed, such as under the window sill.8, solar energy (hot water) transformation to the top Tenants, reserving the installation of solar water heaters require pipeline.
Second, the preparation of the waterway before the transformation
1, to complete the decoration permit.
2, a closed water test, acceptance by the property. If it is found that there is a leakage problem, you can find a property to solve it. If you do not do a water-retaining experiment in the future, if there is leakage in the future, the property will be considered as the owner's decoration has damaged the waterproof layer (in fact, it may be the problem of the building itself), and the responsibility is not clear.
3, consider all the places where the water needs to be installed. For example, the kitchen generally needs hot water for the vegetable basin. This location is to discuss the installation position of the kitchen basin with the cabinet. Then we reserve the outlet for you according to the location of the vegetable basin! The same is true in the bathroom. Wherever there is a wash basin and shower (bath), you have to think about it. In addition, some owners need to install water softeners, small kitchen treasures, etc., you have to explain to the foreman in advance, as well as washing machines, mop pools and other locations.
4, we have a professional construction of the specification "to take the top not to go, open vertical not horizontal."
1) Because the planer underground has a lot of buried pipes, the planer itself is very unsafe. In case of damaging the original underground pipes, it will be very troublesome! And if you go to the ground, in the course of renovation, if the electric drill breaks the water pipe, it will affect safety.
2) When the water pipe leads to the bathroom and meets the place where you need to go out of the water, go down the vertical slot to a suitable height and reserve a shower, basin, washing machine and other outlets. The advantage of doing this is that, when the decoration is finished tiling, you can judge the direction of the water pipe according to the location of the outlet. All the water pipes are vertically upward at the outlet, so as to prevent the water pipes from being damaged for any reason.
3) During the process of renovation and reconstruction of the waterway, do not open a large-scale cross slot! Because opening a horizontal slot can severely damage the structure of the wall. If every home has a horizontal trough, the degree of danger of housing in a few years is simply unimaginable!
4) If the pipe in the buried part has both horizontal and vertical slots, even after the construction is completed, the owner's home has a water rectification roadmap, it will inevitably touch the water pipe in the process of the subsequent renovation (because the slot has been sealed , is invisible pipe).
III. Precautions for acceptance of waterway reform
1, the general use of water pipes in the market is PPR pipe, aluminum plastic pipe, galvanized pipe and so on. The home improvement waterway (water supply pipe) is best to use PPR pipe, because it is connected by heat welding, no water leakage, and the service life is up to 50 years.
2. Slotting of the waterway alignment should ensure that the buried pipe is in the wall, on the ground, and should not be exposed after renovation. Slotting should be careful as long as it can be buried in the pipe, do not damage the structural layer.
3, hot and cold water pipe outlet is generally left hot right cool, hot and cold water outlet is generally 15CM. Hot and cold water exports must be parallel.
5, the waterway transformation is completed to do pressure test, test pressure 8 kg, the regulator time is 30 minutes.
6, after the waterway reform is best to have a waterway map, in order to avoid accidentally hit the water pipe in the subsequent decoration!
7, the most important thing is the water reform team, I suggest you carefully choose professional water reform, electric reform company!
Fourth, on the pressure test before the pressure should be before the water meter before the entrance door is turned off, pressure should pay attention: the pressure should hit 6-8 kg, the voltage regulator time should not be less than half an hour, the owner must carefully check Whether there is leakage at each interface, if it is necessary to allow the installation workers to repair on the spot, and then suppress it until there is no leakage, it is qualified.

Ion-exchange resins are widely used in different separation, purification, and decontamination processes. The most common examples are water softening and water purification. In many cases ion-exchange resins were introduced in such processes as a more flexible alternative to the use of natural or artificial zeolites. Also, ion exchange resins are highly effective in the biodiesel filtration process. SY-007 is a sort o fcation exchange resin that has sulfonic group(-SO3H) in the styrene-diethylene benzene copolymer with 7% cross-linked degree.It is used mainly to soft hard water and produce pure water,as well as used in the hydro-metallurgy and sugar producing and medicine and nosodium glutamate industry, it can be used as catalyzer and dehydrating agent. SY-206 is a sort of Anion Exchange Resin that has quaternary ammonium group[-N(CH3)3OH]in the styrene-diethylene benzene copolymer with 7% cross linking degree.It is used mainly to produce pure water and treat waste water and extract tungsten and molybdenum in biochemical product and hydro-metallurgy. SY-D301 is a sort of anion exchange resin thathas tertiary amine group[-N(CH3)2] in the styrene-diethylene benzene copolymer with macroporous structure.Itis used mainly to produce pure water and ultra pure water,especially suitable for the treatment of the water resource with highcontent salt and organic substance,as well as treat waste water which contains chrome and decolorize sugar solution and so on.
