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

In addition to data control during mould manufacturing and injection moulding, perfect products should be injected. More relevant experience is needed in the design and manufacture of dustbin mould. According to the characteristics, sizes and shapes of different materials, the pre-design evaluation and analysis were made, and the post-test evaluation was carried out.
As the shrinkage rate will change with the change of injection pressure, the cavity pressure of single cavity mould should be as consistent as possible, and the cavity pressure difference of multi-cavity mould should be very small. For single-chamber multi-gate or multi-chamber multi-gate cases, the same injection pressure must be used to make the chamber pressure consistent. Therefore, the position balance of... less

If we do not handle them properly, the service life of the combine chains will be greatly reduced. Therefore, I would like to remind everyone to pay more attention to the use of combine chains.
When transporting corrosive substances, the combine chains will inevitably contact with corrosive substances, and rust-like spots and rust on parts will easily affect the flexibility of chain hinges and rollers in reverse rotation. Stress corrosion and grain corrosion will also occur. The selection of raw materials for chain parts must be paid attention to for the combine chains to be used in the case that the transported materials contain corrosive substances.
After transporting corrosive substances using the combine chains, pay attention to cleaning in time, because if the combine chains and corrosive substances adhering to its surface are not cleaned in... less

Why is there a problem with the fastness of nylon fabric? In fact, the fastness of nylon fabric printing is affected by many factors such as the type of nylon fabric. Therefore, in the study of the fastness of waterproof nylon fabric, it is necessary to analyze the printing adaptability of different materials, select the most suitable ink and other materials, and pay attention to the operation technology to ensure the printing effect.
Different from natural fibers, nylon or polyester fibers are all synthetic fibers. Their basic characteristics are very compact molecular structure, little or no water absorption, and the surface feel of fibers is very smooth.... 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

Enameled wires and electromagnetic wires mainly use insulating electrostatic powder coatings. Currently, they are mainly applied to insulated oxide film electromagnetic wires treated with concentrated sulfuric acid instead of metal aluminum wires, and can also be applied to enameled wires coated with insulating paint.
Since the coating thickness of ordinary powder coating is applicable to round wires with a diameter of 1.6mm or more or flat wires with a width x thickness of 1.6 mm x 1.6 mm or more and insulating coatings with a coating thickness of 40μm or more, it is not applicable when the thin coating is required. If the ultra-thin powder coating is used, the thickness of 20-40μ m can be achieved, but due to the high... less
