Introduction<\/b><\/h2>\n

Oliver & Batlle began using vacuum loading systems in complex industrial applications many years ago. The experience gained with difficult-to-handle powdered products such as Aerosil, carbon black, glass microspheres and bentonite prompted O+B to develop an R&D project focused on creating a specific solution for this application: the vacuum loading system for powdered raw materials, called <\/span>DISPERVAC<\/b>.<\/span><\/p>\n

DISPERVAC<\/b> solves the problem of loading raw materials that are difficult to handle due to their volatility, dirtiness, contaminating characteristics or health risks.<\/span><\/p>\n

Several chemical industry machinery manufacturers have been introducing inline mixing systems to the market for years for the incorporation of powdered raw materials into dispersion processes. With the aim of offering a robust and competitive alternative, Oliver & Batlle developed the <\/span>DISPERVAC<\/b> system, which combines vacuum feeding of solids with the <\/span>Polimix<\/b> dispersion system, achieving a highly efficient, safe, and versatile solution. After analysing the various processes available on the market, we believe our <\/span>DISPERVAC<\/b> technology is also particularly interesting for incorporating pigments such as titanium dioxide (TiO<\/span>?<\/span>), which is widely used in the paint industry for its hiding power and colorimetric performance but is difficult to handle and expensive.<\/span><\/p>\n

In the next article, we will present some ideas that will support the promotion and use of the <\/span>DISPERVAC<\/b> system, which we hope will be of interest to you.<\/span><\/p>\n

Advantages of vacuum loading of powdered products with the DISPERVAC system in paint and ink manufacturing<\/b><\/h2>\n

Nowadays, pigment cost is one of the most significant factors in the manufacturing of paints and inks. Reducing pigment usage can represent a considerable cost savings and improve overall process profitability.<\/span><\/p>\n

One of the most widely used pigments is <\/span>titanium dioxide (TiO?)<\/b> a costly and difficult-to-handle material. Depending on the formulation, it can suppose for 25% to 40% of the total production cost. There has long been ongoing discussion around the possibility of classifying TiO? as a carcinogenic substance, which could eventually lead to regulations restricting its use.<\/span><\/p>\n

In anticipation of such a scenario, <\/span>Oliver + Batlle <\/b>has developed a vacuum powder loading system compatible with dispersion machines, designed to streamline the handling of powdered pigments and facilitate their safe and efficient incorporation into the production process.<\/span><\/p>\n

Vacuum loading of powdered pigments in paint and ink manufacturing offers major advantages, especially for dispersing pigments such as TiO?:<\/span><\/p>\n

    \n
  1. Enhances the colorimetric strength<\/b> of the pigments.<\/span>
    \n<\/b><\/span><\/li>\n
  2. Allows for reduced pigment usage<\/b>, as air-free dispersions ensure better particle distribution and more efficient processing, avoiding the \u201cairbag effect\u201d caused by excess air.<\/span><\/li>\n<\/ol>\n
