HDPE is a part of the plastic recycling market with rapid growth. This is mainly because it is easy to reprocess, has a limited degradation characteristics and is widely used in packaging. The main recycling is to reprocess 25% of recycled materials, such as post consumer recyclables (PCR), with pure HDPE to make bottles not in contact with food. In addition, due to the good insulation performance of HDPE storage tanks, polyethylene is used in many cables, and has good impact resistance even in low environment, In addition, this type of storage tank is more convenient for processing, and can be processed again after use, but it can not be used in industries directly contacting food after secondary processing.

The small softening point of PPH storage tank is 108 ℃, and the large fragmentation point is - 70 ℃, so PP storage tank can generally be used to hold liquid with temperature ranging from - 40 ℃ to 60 ℃. The feed inlet, discharge outlet, liquid level gauge outlet, flange, etc. on the PPH storage tank body are all integrally formed and welded at one time, without additional feed inlet and outlet. When containing acid-base substances, acid-base resistant gaskets shall be provided. When organic substances (especially organic solvents) are contained, insoluble rubber gaskets shall be provided. PPH storage tank is made of polypropylene, which can contain inorganic acids, malic acid, salts, ammonium, alkalis, oils and most gaseous organic substances at normal temperature and pressure. PPH storage tank cannot be used to contain strong oxidants, such as concentrated sulfuric acid, concentrated nitric acid, etc. When using PPH storage tank, we should not forget that it is just a tool we use. If the tool is not used properly, it will also break down. Therefore, why we use PPH storage tank with different life depends on how we treat them.

PPH storage tank is a new product of polypropylene storage tank. With the rapid development of economy, the development of PPH storage tank is particularly rapid, from the previous single series to the current various types. The manufacturer of PPH storage tank is generally only responsible for the design, production, loading and transportation of the storage tank within the scope of the project. The subsequent unloading and installation are the responsibility of the customer. The manufacturer arranges one more project manager to direct the unloading and installation on site, but generally the manufacturer does not have so many project managers to assign, Therefore, it is particularly important for customers to know how to unload and install PPH storage tanks. In terms of unloading, before the storage tank is transported to the installation site for unloading, it is recommended that the customer representative inspect the storage tank to confirm that the storage tank is not damaged during transportation.

For the treatment of corrosive gases (such as acid and alkaline waste gas) in PPH waste gas tower, liquid absorption method is often used. The key to control the waste gas by liquid absorption is the selection of purification equipment. The main development is acid and alkaline waste gas purification process and equipment with high purification efficiency, simple operation and management, and long service life. This process and product are characterized by simple structure, low energy consumption, high purification efficiency and wide application range, and can effectively remove water-soluble gases such as hydrogen chloride (HCl), hydrogen fluoride (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), cyanuric acid gas (HCN), alkali vapor (NaOH), hydrogen sulfide gas (H2S), formalin (HCHO), etc. The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and sodium hydride absorption liquid are fully contacted, absorbed and neutralized by gas-liquid two-phase reaction. After purification, the acid mist waste gas is dewatered and defogged by the demister, and then discharged into the atmosphere by the fan. The absorption liquid is sprayed down from the tower top after being pressurized by the water pump at the tower bottom, and then flows back to the tower bottom for recycling.
