Users who have some knowledge of chemical drums may know that deformation is inevitable after they are used for a period of time. What is the reason for this problem? The following is about industry Plastic bucket manufacturer Let's get to know together!    

I believe you are not unfamiliar with the relevant knowledge of chemical plastic bucket. The above article has described these contents, but as a professional user, mastering these knowledge is far from enough. In order to further promote the understanding of users, the prominent characteristics of transparent raw materials used by professionals are summarized as follows: transparent Chemical plastic bucket First, it must have high transparency, followed by certain strength and wear resistance, impact resistance, good heat resistance components, excellent chemical resistance and low water absorption. Only in this way can the transparency requirements be met and remain unchanged for a long time in use. In addition, this chemical plastic bucket will encounter common problems during use. Due to the high light transmittance of transparent plastics, the surface quality of plastic products must be strictly required, and there should be no spots, pores and whitening phenomenon. Mist halo, black spot, discoloration, poor gloss and other defects lead to damage of raw materials and equipment during the whole injection molding process. Mould and even product design should be highly valued, and strict and even special requirements should be put forward. Transparent chemical plastic bucket must first have high transparency, then have certain strength and abrasion resistance, impact resistance, good heat resistance, excellent chemical resistance and small water absorption. Only in this way can we meet the requirements of transparency and remain unchanged in long-term use. The following table lists the performance comparison of PMMA, PC and pet. Because there are many varieties, this is only the average value. The actual data of different varieties are different. PET data (mechanical) is the data after stretching.

In the process of use, this chemical plastic bucket will also encounter common problems. Due to the high light transmittance of transparent plastics, the surface quality of plastic products must be strictly required, and there should be no spots, pores and whitening phenomenon. Mist halo, black spot, discoloration, poor gloss and other defects lead to damage of raw materials and equipment during the whole injection molding process. Mould and even product design should be highly valued, and strict and even special requirements should be put forward. Secondly, due to the high melting point and poor fluidity of most transparent plastics, in order to ensure the surface quality of products, it is often necessary to fine tune the process parameters such as high temperature, injection pressure, injection speed, etc., so that the mold can be filled during the injection process without generating internal stress, resulting in product deformation and cracking.

The production of each product is suitable for its own application, and the chemical plastic bucket we are talking about today is no exception. Its application can be used to install liquid that will produce chemical reaction. At this time, we should take preventive measures to confirm its reaction and whether it can withstand its temperature. Chemical plastic buckets are usually used to store liquids. At room temperature, there is no problem with salt, alkali and other mixtures. Plastic drums for chemical industry cannot be used for strong oxidizing liquids in the plant, such as sulfuric acid with temperature higher than 60 ℃ and concentration higher than 75%, and concentrated nitric acid with concentration higher than 30%. In addition, it is used to produce plastic drums for chemical industry. They can also be used to store and transport various liquids. They have good characteristics for special dangerous goods packaging. They are not fragile, rust free, light weight, and have excellent oil resistance and strong corrosion resistance. They are mainly used for packaging dangerous goods that require heat insulation, moisture resistance, pressure resistance and corrosion resistance. It is precisely because its application field is so wide that it has such a good development prospect.
