It is reported that Shandong's vigorous construction of highway projects this year, asphalt demand increased slightly compared to the same period last year. However, refineries in Shandong Province suspended production under the pressure of raw material costs, resulting in insufficient supply of asphalt in Shandong. Although the Shandong asphalt market has domestic resources and imported resources to support the market supply and demand balance, according to statistics, in July this year, the import of asphalt in Shandong Province was basically the same as last year.
Due to the shortage of supply in the market, sales of bitumen production enterprises are very hot, and individual companies even appear to be out of stock. Zhonghai State heavy traffic bitumen AH70# and 90# are quoted at 2,450 yuan (ton price, the same below); Qilu Petrochemical heavy traffic bitumen AH90# is quoted at 2,380 yuan, A-grade heavy traffic asphalt is quoted at 2,430 yuan; Shida Shenghua heavy traffic asphalt The price of AH70# was raised to 2,450 yuan; the price of Dongming Petrochemical's heavy traffic asphalt was maintained at 2,350 yuan; the price of Dawanghua's heavy traffic asphalt AH70# and 90# was 2,400 yuan.
It is understood that at present, some construction units are under pressure from the shortage of resources in Shandong Province and have turned their attention to the northwest region where resources are relatively loose. At present, a small number of construction units have purchased asphalt from Xi'an Petrochemical.
Drying equipment is a crucial component in many industries, including food processing, pharmaceuticals, and chemical manufacturing. These machines are designed to remove moisture from materials and products, which can help to increase their shelf life, improve their quality, and reduce their weight.
There are many different types of drying equipment available on the market today, each with its own unique set of features and benefits. Some of the most common types include air dryers, rotary dryers, fluidized bed dryers, and freeze dryers.
Air dryers are the simplest and most affordable type of drying equipment. They work by blowing hot air over the surface of the material or product being dried, which causes the moisture to evaporate. Rotary dryers are similar to air dryers, but they use a rotating drum to agitate the material and improve the drying process.
Fluidized bed dryers are a more advanced type of drying equipment that use a bed of hot air to suspend and dry the material being processed. This allows for faster and more efficient drying, as well as improved product quality.
Freeze dryers are a specialized type of drying equipment that are used primarily in the pharmaceutical industry. They work by freezing the material being dried and then removing the moisture through a process called sublimation.
Regardless of the type of drying equipment used, it is important to choose a machine that is well-suited to the specific needs of your industry and application. Factors to consider when selecting a drying machine include the type and volume of material being processed, the required level of moisture removal, and the available space and resources for installation and operation.
Overall, drying equipment is an essential tool for many industries, and can help to improve product quality, reduce waste, and increase efficiency. With so many different types of machines available on the market today, it is important to carefully evaluate your options and choose a machine that will meet your specific needs and requirements.
