Flocculant is a kind of polymer, it is made of organic flocculant polymerization, polymer flocculant can be used as water treatment flocculant, polymer flocculant is divided into anionic, cationic, nonionic, amphoteric, and there are synthetic resins are also belong to a kind of flocculant. Mainly used in the purification of drinking water and industrial wastewater, special water quality treatment (such as oil-containing sewage, printing, dyeing and papermaking sewage, smelting sewage, containing radioactive qualities, containing Pb, Cr and other toxic heavy metals and F-containing sewage, etc.). In addition, it is widely used in precision casting, oil drilling, tanning, metallurgy and paper making.
In winter, flocculant pipelines are subject to freeze blockage and condensation, especially the old blockage of pump inlet pipelines, which requires accompanying heat insulation. Simple heat preservation measures, such as external parcel heat preservation cotton, and can not solve the problem of anti-freezing. Must use a kind of sustainable heat supply accompanied by heat preservation equipment to be insulated, in this recommended self-limiting temperature accompanied by the heat of the outside with the heat preservation cotton, realize the anti-freezing heat preservation.
The electric heating cable to use the PTC semiconductor material as the heating element, the internal can according to the outside temperature, realize the automatic temperature control in 20 ℃, is the pipeline to prevent freezing often choose the kind. And the flocculant pipeline is better to maintain the temperature between 5-20 ° ℃. Self-limiting temperature accompanied by heat tape to fully meet the needs of its anti-freezing.
In addition, the self-limiting temperature electric heating cable tape is used in the pipeline accompanied by heat on the installation is also relatively convenient, it can be based on the diameter of the pipe and other relevant parameters, to determine the spiral or straight laying of the situation, and can be on the pipeline attachments (such as valves, elbows, etc.) or the complexity of the three-way pipeline to take special care of to do the local to the appropriate. In addition, for the pipe network, can also be equipped with control box to realize centralized control, so for the flocculant line and other solvents pipeline heating, self-limiting temperature heating cable is a better choice.
