Facing the high temperature, 12V DC Freezer https://www.chinafreezers.com/product/dc-freezer/ may have various problems. In order to avoid accidents, it is very important to use specifications and clean regularly. Regular maintenance can also prolong the service life of the freezer. How to use the freezer correctly?
The freezer should be cleaned at least twice a year. When cleaning the freezer, please turn off the power supply, gently scrub with a soft cloth dipped in water or detergent, and then wipe the detergent with water. After cleaning, please firmly plug in the power plug and check whether the temperature controller is positioned correctly.
Some users want to save time and energy when defrosting freezers. They use sharp metal parts: blades, screwdrivers, etc., which accidentally pierce the lining during defrosting, thus damaging the evaporator. When defrosting, let it stand for a while before the frost melts, and then remove it with a defrosting... less

Memory fiber refers to some characteristics of the initial state that can be memorized when the fiber is formed at one time. The fiber can undergo any deformation after being formed. The deformation can be fixed under the action of lower temperature or external force. When the deformed fiber is stimulated by specific external temperature or external force, the fiber can return to the initial state. In short, the fiber can rapidly deform under the action of external factors and can rapidly recover the deformation under the action of external stress. Fabrics made of such fibers are called shape memory fabrics.

As the middle interlayer contains a large amount of air, it can insulate sound and heat, has no combustible substance, has a fire prevention grade of B1, is waterproof, dampproof and free of harmful gas release, has large specific strength and high specific rigidity per unit mass (the structural rigidity is 1.7 times of rib type), and is not easy to deform. The invention completely overcomes the defects of deformation, middle collapse and the like of other decorative panels when a single piece is large in area, is convenient to process and apply, can cut and fold edges at will, can ensure the service life of products to be more than 30 years through fluorocarbon coating on the surface, and... less

Once this happens, it will affect the quality of the panel. Do you know what are the main factors that affect the temperature field during casting and rolling aluminum solid panel?
1. Effect of latent heat of crystallization. The latent heat of crystallization Q═393. 59J/g of aluminum is greater than the sensible heat released during casting and rolling, which will significantly reduce the cooling rate of the cast and rolled metal.
2. Influence of mass flow. During the casting and rolling process, both the roller and the aluminum strip billet are moving, i.e. there is mass transport phenomenon, which makes the solution of the temperature field extremely complicated.
3. Influence of contact thermal conductivity. In the casting-rolling process, most of the heat generated by the cooling of liquid metal and solidified solid metal in the roll gap is... less

If you want to buy high-quality products, the more professional knowledge you know, the more confident you will be. So if you don't know, can you not buy quality products? Of course not, you only need to learn a few simple tips, and you can also choose the best and most suitable among many Water Filter Spare Parts https://www.kokoelectric.com/ .
The water pipe of the water filter is one of the fittings of the water filter. Although it is only a very small pipe, it is impossible for the water filter to filter sewage, let alone water source transportation, without its assistance. Buying a high-quality water pipe is of great help to the safe use of the water filter, so how to judge the quality of the PE pipe of the water filter?
Water filter pipes are widely applicable. Water purification products in the water purification market can basically be used. The selection can be tailored to different types of... less

The production of Printing Pile Fabric https://www.warpknittedfabric.com/product/printing-fabric/ generally includes four processes: screen plate making (or cylinder engraving), color paste preparation, pattern printing and printing post-treatment.
Printing, like dyeing, makes dyes and fibers dye. The difference is that when dyeing, the fabric is fully and evenly dyed with dyes, while when printing, dyes of a certain color only dye certain parts of the fabric, thus causing the fabric to present patterns of various colors. In order to obtain various pattern patterns on the fabric and achieve the purpose of local dyeing, printing cannot be carried out in the dye liquor like dyeing, but the paste must be prepared into the original paste as the dye carrier, then the dye and necessary chemical additives are added to prepare printing paste and printing on the fabric, so as to overcome the... less

Bare wire is annealed and softened, then painted and baked many times. So, in the winding process of copper enameled wire https://www.xinyu-enameledwire.com/product/enameled-copper-wire/ , what should we pay attention to?
1. Scratch during the winding process. Because the outer surface of the copper enameled wire is a layer of the insulating film, which is simply scratched by the corners of metal objects, it is necessary to pay attention to the contact parts between mechanical equipment and enameled wire during the winding process and minimize the external force applied to the enameled wire. Avoid damage to paint film.
2. The tension of coiling thread. In the winding process, the tension applied to the copper enameled wire should be as small as possible to reduce the modification of enameled wire performance as much as possible.
3. Before the coil is used, it is admitted that the copper enameled... less

At present, table mould manufacturing technology is also developing in the direction of accelerating information drive, improving manufacturing flexibility, agile manufacturing and system integration. In order to produce the table mould, in view of the current domestic mould manufacturing technology level and quality, the following table mould manufacturing conditions are introduced for your reference.
1. Cleaning workshop
In a dirty environment, it is impossible to produce high-quality table mould. The mould production area should be kept highly clean and the maintenance and management level is higher than that of the product production area. Therefore, dust removal and cleaning should be done in the mould manufacturing area before the mould manufacturing starts.

In fact, for outdoor protective clothing, pure cotton clothing is not necessarily good. Because very sweat-absorbent clothes, such as pure cotton, will absorb sweat from the body, but due to the relatively large amount of sweat that is emitted, it is easy to remain on the clothes. Over time, it will make the clothes stink and make people unable to wear them. So what kind of Outdoor Protection Fabric(WANSHIYITEX) https://www.wanshiyitex.com/ is good?
Nowadays, outdoor sports are closely related to a healthy life. Outdoor clothing is an essential part of our family life and outdoor life. Of course, all kinds of professional sports fabrics, functional fabrics and technological fabrics are born for this purpose. Since human beings began to pay attention to outdoor sports, people began to explore, develop and study new fabrics to minimize the influence until negligible. They continued to... less

Due to the structure of the high-strength chain (the links are connected by hinges) and the load during operation (with tight and loose edges), the normal failure mode of the transmission high-strength chain is the fatigue failure and high of the high-strength chain parts. The elongation of the strength chain.
At present, the quality of high-strength chain parts in China chain factory(GETECHAIN) https://www.getechain.com/ has been greatly improved compared with the 1970s and 1980s. Most of the high-strength chains produced by professional high-strength chain manufacturers with a certain scale have interchangeable sizes. Indicators such as static strength have reached the corresponding standard requirements. However, important quality indicators such as fatigue resistance and... less
