Chengdu Chemical Production Line

Description :

　　Chemical comprehensive production line process for brushed paint:

　　1. Dilution ratio: If necessary, dilute with clean water. To ensure better elasticity of the paint film, do not dilute.

　　2. Construction conditions: Construction shall be carried out in an environment with a temperature above 5 ℃ and a relative humidity below 85 ℃.

　　3. Storage method: Store in a cool and dry place, with a temperature above 5 ℃ and below 40 ℃.

　　4. Safety: The raw materials do not contain harmful substances such as mercury and lead.

　　The construction of elastic brushed paint is a newly developed construction technology, and the chemical comprehensive production line technology highlights the crack resistance and main texture effect of the product. The process is as follows:

　　1. Base treatment: Before base treatment, the wall needs a certain amount of time for maintenance.

　　2. Apply sealing primer: After the putty is completely dry, apply one coat of sealing primer. Sealing primer generally does not require additional diluent for dilution. Before painting, the base layer should be polished flat, and floating dust should be cleaned. Construction tools should be kept clean to ensure that the sealing primer is not contaminated in any way. The construction method of roller coating is generally used for sealing primer. It is both convenient and fast.

　　3. Brushing brushed topcoat: Apply elastic brushed paint with a special pattern roller to reduce bubbles and pinholes caused by the roller. The viscosity adjustment is relatively high during product manufacturing, so adding water is prohibited during construction.

　　4. Apply elastic topcoat: To increase the thickness and three-dimensional texture of the brushed paint, it is recommended to apply a flat layer of elastic paint on the brushed paint surface.

　　5. Precautions: Precautions for the construction of brushed paint include increasing cohesiveness, appropriately extending drying time, and paying attention to the "initial drying resistance" of the coating.

　　The outdated technology of heat exchange equipment is one of the important reasons for the low efficiency of energy utilization in China's chemical comprehensive production lines. The research and development of energy-saving heat exchange equipment is an important way for engineering energy conservation today. With the increasing shortage of conventional energy, the further improvement of energy consumption requirements for modern chemical integrated production lines, and the continuous expansion of industrial reproduction scale, how to ensure the utilization of energy under the premise of safety and production has received widespread attention from countries around the world, and various related research has also become a hot topic in academia and various engineering departments.

　　Principles of Chemical Engineering Experimental Device - Bernoulli Experimental Device

　　Purpose of the experiment:

　　1. Familiarize oneself with the concepts and conversion relationships of various energies and pressure heads in fluid flow, and deepen the understanding of Bernoulli's equation.

　　2. Observe the variation of various energies (or pressure heads) with flow velocity.

　　Main configuration:

　　The Bernoulli experimental setup mainly consists of a water storage tank, a water pump, a high-level water tank, a rotor flowmeter, a Venturi tube, a pressure measuring tube, and a stainless steel frame.
