1, solid class
The main components of solid sewer dredging agent are caustic soda and aluminum powder, which react with water through strong alkali, and at this time, some heat will be generated. When strong alkali reacts with aluminum powder, it will produce a lot of gas. The working principle is to rely on corrosivity and gas pressure, and then flush the blockage, so as to achieve the purpose of dredging the pipeline.
2. Liquid
The physical form of liquid pipeline dredging agent is gel, and the main component is surfactant, so that water will not disperse, but naturally sink, and then it can be used as a plugging point, which is beneficial for the surfactant to play its role and achieve the purpose of physically decomposing the plug. Generally speaking, the liquid pipeline dredging agent is mild when used, and has no violent reaction, so it is safer to use and has no damage to the pipeline.
Second, how to use sewer dredge agent
When the sewer is blocked, the powdery solid component of this medicine is first added to the blocked pipeline, and then the corresponding liquid component is added.
The one-time addition amount of the two components can be appropriately changed according to the amount of accumulated water in the blocked pipeline. When the stagnant water is 350 ml ~400 ml, the amount of powder component is 4~9 g, and the liquid component is 200~300 ml. After about 15 minutes, the heating reached its peak and melted the oil impurities. About 30 minutes, the hair is completely decomposed, and the blocked pipe can be dredged.
Third, use sewer dredge.
1. Sewer dredge can quickly dissolve oil, hair, vegetable leaves, tea residue, pet hair, human excrement, soap, toilet paper, mop hair, other kitchen garbage and small blockages. Sewer dredge agent does not corrode cast iron and plastic pipes! Can't be used on aluminum products (aluminum pipes are characterized by low hardness. Use 1 yuan coin to lightly stroke the pipe, and scratches indicate that it may be an aluminum pipe).
2. The sewer dredge agent can't solve the blockage caused by a large number of foreign objects falling in, such as combs, toothbrushes, hairpins, chopsticks, rags, soap boxes, plastic bottle caps, small stones, various bones and mud. Sewer dredging agent can not be used for long-term use of more than ten years of urine alkali scaling caused by blockage.
3. For the blockage of cast iron pipes, the use of sewer dredging agent is not restricted, and there will be or may be damage. For plastic pipes (especially soft plastic pipes), because there will be an exothermic process in the reaction process, if the amount of sewer dredging agent is too large at one time, the pipes may be deformed by heat due to the instantaneous temperature increase.
4. The main components of sewer dredging agent are calcium carbonate, calcium hypochlorite, foaming agent and patented instant quick-acting factor. Therefore, the dosage of sewer dredging agent should not exceed 200g at a time. When the weather is cold, hot water can be injected to preheat the pipeline first. Therefore, it should be used in accordance with the principle of "a small number of times".
