Iron drum is a common packaging and transportation product. The iron drum is mainly used to hold various liquids. In order to ensure the safety in transportation, the sealing requirements are strictly required. Once the sealing is not tight, it will lead to our products. Loss, so it's important to understand the factors that affect the tightness of the barrel, which can help us avoid these problems. In fact, when there is a problem with the tightness of the iron drum, we must first find out what went wrong, such as: there is a problem with the sealing of a certain iron drum, or there is a problem with the sealing of the whole batch of products, and the factors affecting the sealing performance of the iron drum are The following aspects:
1. The iron barrel is not good. Usually, some manufacturers do not mix waste materials to reduce the cost of the product, which leads to a decline in the quality of the raw materials, thereby affecting the tightness of the iron drum;
2, the iron barrel material formula is not professional. There are many kinds of materials for producing chemical iron drums. The commonly used materials are polyethylene and polypropylene. The materials and additives used in the production of chemical iron drums are different, and the properties of different raw materials are quite different. Some materials are hard, some materials It is softer, and to improve the tightness of the iron drum, it is necessary to fully understand the material properties and give full play to its advantages. The proportion and formulation of the materials are critical, which is an important factor affecting the tightness of the iron drum;
3. The iron drum mold is not precise enough. The lack of precision of the mold will affect the fit of the iron lid and the barrel. The precision of the mold is also an important factor affecting the sealing of the chemical drum.
4. The equipment has not been debugged. It is usually necessary to commission the equipment before production. The poor commissioning will also affect the sealing of the chemical iron drum.
