Extraction and Separation of Crude Cellulose Sampling and Degreasing—Approximately 4.000 g of a sample of barley straw was accurately weighed, and the fat was immersed in diethyl ether (about 2 to 3 hours). After suction filtration, the sample was transferred to a 500 mL Erlenmeyer flask in a reflux flask.
Boiled 200 mL 0.128 mol/L H2SO4 solution and one drop of foaming aid were added to the acid treatment-Empty flask. The reflux condenser was connected and heated to boil. The boiling time was 30 min. After heating was stopped, the solution immediately passed through the Buchner funnel. With suction filtration, the residue is washed with boiling water until it is not acidic.
The main factors affecting the determination of crude fiber content are the particle size and temperature control conditions of the stalk crushing in the process of the fiber tester. In addition, due to the different altitudes and climatic conditions of the Highland barley straws.
If we can fully understand and determine the relevant conditions of the crude fiber through the fiber measurement instrument, and adopt modern technology to effectively treat the highland straw, the cellulose, hemicellulose and lignin contained therein will be degraded and transformed. Therefore, it can increase its nutritional value, improve palatability, and then it can become a potential feed resource for better utilization of livestock and poultry. This has the potential to rationally and effectively utilize the abundant barley straw resources and greatly increase the utilization efficiency of straw. Very important meaning.
Product Description
1. Description
In the drilling process, the drill bit is the main tool to break the rock and the wellbore is formed by the drill bit breaking the rock. How well a wellbore is formed and the length of time it takes are not only related to the characteristics of the rock in the drilled formation and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation. Reasonable selection of drill bits plays an important role in increasing the drilling speed and reducing the overall cost of drilling.
The drill bit is one of the important tools for oil drilling work. Whether the drill bit adapts to the rock properties and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed and drilling cost.
2. Specifications we can offer
At present, there are many types of drill bits used in the petroleum industry and mining industry. The drill bits are classified according to different drilling methods. They can be divided into PDC drill bits, roller cone bits, scraper bits and mining diamond coring bits. These drill bits are the most basic drill bits and we all can provide.
