Here’s our guide to the essential appliances for a cozy summer home.

When shopping for a washing machine, consumers tend to focus on capacity, energy efficiency and price, but rarely have an in-depth understanding of the inner cylinder, the core component that directly affects the effectiveness of washing and the life of the machine. As the direct contact surface of clothes washing, the material and manufacturing process of the inner cylinder determine the durability, cleaning efficiency and the degree of care of the clothes. Next, I will popularize the material and process of the inner cylinder of the washing machine for you, so that you can understand more about the washing machine.

Ⅰ.Material types and characteristics of inner cylinder

At present, the inner cylinder of washing machine on the market is mainly made of stainless steel, engineering plastics and composite materials, each with its own characteristics.

1. Stainless steel inner cylinder: among them, 304 stainless steel is most commonly used, with good corrosion resistance and mechanical strength, suitable for long-term humid environment. The cost of 430 stainless steel is lower, but the ability of antirust is a little weak, rust spot may appear in long-term use.

2. Engineering plastic inner cylinder: mainly used for mini or portable washing machine, light weight, low cost, but poor resistance to high temperature, long-term use may be deformed. Some high-end models use reinforced plastics (such as fiberglass) to improve strength and durability.

3. Composite material inner cylinder: the core of the composite material inner cylinder is humanized design. With its smooth surface and reasonable structure, it reduces the winding of clothes and makes the washing process more convenient and convenient.

Ⅱ.Surface treatment process

The surface treatment process of the inner cylinder plays a key role in the washing effect and the maintenance difficulty of the machine.

1. Polishing treatment: in polishing treatment, high-precision polishing can make the surface of the inner cylinder as smooth as a mirror, greatly reducing friction with clothing, reducing clothing wear, so that clothing can be”Undamaged” in washing, and smooth surfaces make it easier for stains to slide down.

2. Antirust coating: on the antirust coating, some stainless steel inner cylinder adopts nano ceramic coating and other antirust coatings to enhance corrosion resistance, but the coating process is uneven, and the inferior coating is easy to peel off after long-term washing.

3 antibacterial treatment: antibacterial treatment, high-end models add silver ions or photocatalyst coating, effectively inhibit the growth of bacteria, create a healthy environment for clothing washing.

Ⅲ.The correlation between material and process

The inner cylinder material is closely related to the process, which is not independent, but deeply integrated and jointly shapes the performance of the washing machine. Although high-quality stainless steel has the advantage of corrosion resistance, it needs electrolytic polishing or nano-coating process to minimize the probability of stain adhesion. If the plastic inner cylinder is not strengthened, after using for a period of time, it must be deformed and aged. Although the high-end ceramic coating anti-fouling ability, but if the substrate is easy to rust low-grade stainless steel, coating durability will be seriously damaged. Therefore, it is necessary to carry out all-round and deep-level collaborative optimization of materials and processes, so that washing machines can have long life, reduce clothing wear and stabilize washing effects.

Conclusion

The inner cylinder of the washing machine is not a simple metal barrel. Its material selection and surface treatment process jointly determine the durability of the machine, washing effect and clothing protection ability. Consumers should not only pay attention to the price and appearance, but also examine the material and process of the inner cylinder according to their own needs to ensure the reliability of long-term use. Scientific choices can make the laundry experience more efficient and lasting.
