High pressure disperserBy utilizing high-pressure fluid shear force, cavitation effect, and impact, combined with precise grinding valve design and intelligent control system, the dispersion problem of high viscosity materials has been effectively solved. The following analysis will be conducted from four aspects: technical principles, equipment advantages, application scenarios, and operational optimization:
1、 Technical principle: Particle refinement achieved through high-pressure fluid dynamics
The core of a high-pressure disperser is to pressurize the material to a maximum of 58000 psi (approximately 400 MPa) through a high-pressure pump (such as a positive displacement reciprocating plunger pump), and then the fluid passes through a specially designed grinding high-pressure valve at high speed. During this process:
Shear force crushing: When the fluid passes through the adjustable slit grinding valve, the linear velocity can reach 150-300 m/s, generating extremely strong hydraulic shear force, directly crushing agglomerated particles in high viscosity materials.
Hole effect: Under high pressure environment, the local pressure of the fluid drops sharply, forming tiny bubbles and collapsing instantly, generating shock waves to further crush particles.
Impact effect: The material undergoes high-frequency impact with the nozzle structure inside the dispersion chamber, enhancing the dispersion effect.
2、 Equipment advantage: Adapt to the four major characteristics of high viscosity materials
High voltage continuous operation capability
Core components such as ceramic plungers and alloy high-pressure grinding valve bodies support long-term high-pressure stable operation, and can maintain performance even when handling high viscosity materials such as silicone and resin.
Experimental to industrial grade equipment is fully covered, with a maximum flow rate of 2400 L/h for industrial grade models, suitable for large-scale production needs.
intelligent control system
Real time monitoring of pressure and temperature to avoid material denaturation caused by local overheating (such as in the food and pharmaceutical industries).
Split pump body structure and safety overpressure protection function reduce operational risks.
modular design
Optional single/dual booster versions, supporting multiple modes such as pressure balanced load homogenization valve, jet collision interaction chamber, secondary homogenization (back pressure module), etc., flexibly responding to materials of different viscosities.
Material and Process Assurance
The whole machine is made of stainless steel material, which complies with GMP standards and supports online cleaning and sterilization to ensure the hygienic production of high viscosity materials (such as pharmaceuticals and food).
3、 Application scenario: Covering high viscosity material processing in multiple industries
High pressure dispersers have been widely used for dispersing high viscosity materials in the following fields:
Chemical industry: Production of ultrafine powder coatings and nanoparticles, processing resin systems with viscosity up to 5000 cP.
Food industry: Nanocellulose extraction, dairy homogenization, solving the problem of particle aggregation in high viscosity sauces (such as chocolate sauce).
Pharmaceutical field: preparation of liposomes and emulsions, improving bioavailability by refining drug particles.
Materials Science: Homogenization of pulp fibers, dispersion of ceramic pulp, optimization of material properties.

parameter matching
Adjust pressure and flow rate based on material viscosity (e.g. higher pressure is required for high viscosity materials).
Determine acetylene flow rate (flame atomization scenario) through standard liquid testing to optimize combustion efficiency.
auxiliary design
Integrated vacuum system (such as 0.07 MPa vacuum degree) to reduce bubble interference and improve dispersion fineness.
Adopting a dual axis structure (high-speed mixing shaft+low-speed scraping shaft) to prevent high viscosity materials from hanging on the wall.
Maintenance and Upgrade
Regularly inspect the wear of ceramic plungers and grinding valve bodies to ensure stable continuous high-pressure operation.
Upgrade to an intelligent control system to achieve automated regulation of pressure, temperature, and flow rate.
