How to purchase a good quality PP pickling tank?
How to purchase a good quality PP pickling tank? If you want to improve the production efficiency, you need better production equipment. Today, Xiaobian wants to discuss with you how to choose a good quality PP pickling tank. If you want to use PP pickling tank for a long time, you should pay attention to what will affect the service life of PP pickling tank. Here are some lists of Xiaobian. For example, in terms of material selection, it will affect the service life of PP pickling tank Life.
First, I would like to talk about that if the vessel steel is a common PP pickling tank, the steel with a yield limit of 245MPa ~ 345mpa can be used, and 16MnR steel is a common low-alloy high-strength steel with a yield strength of 350Mpa, which has good comprehensive mechanical properties, welding performance, process performance and low-temperature impact toughness. Of course, there are many materials for manufacturing the metering tank, such as: carbon steel, aluminum, titanium, plastic, large capacity metering tank with carbon steel shell, anti-corrosion non-ferrous metal plate lining, carbon steel shell, plastic lining, rubber lining.
Second, many people may have some doubts about polypropylene through the use of polypropylene material. Let's talk about it briefly here. Firstly, the flange must have enough strength and hardness. In order to meet the simple connection conditions and better sealing performance, high-quality polypropylene material is needed here.
We often say that polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties. The absolute value of mechanical properties of polypropylene is higher than that of polyethylene, but it is still a low variety in plastic materials, and its tensile strength can only reach 30 MPa or slightly higher. PP with larger isotactic index has higher tensile strength, but with the increase of isotactic index, the impact strength of the material decreases, but it will not change after falling to a certain value. Therefore, the purchase of good quality also depends on the material of PP pickling tank. If you choose to purchase PP pickling tank, you may as well have a look at Taicang Dongsheng chemical anti-corrosion equipment factory.
