Synthetic Amorphous Precipitated Silicon Dioxide Used For Tires

Brief Intruction for precipitated silica

Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.

Here is a brief look at how precipitated silica is made:

Step 1: Precipitation

Sodium silicate solution (water glass) and mineral acid are reacted in an agitated vessel to produce a slurry of amorphous silica particles. The critical physical properties of precipitated silica, such as particle size and porosity, are controlled during this stage of the process by manipulating, among other things, the composition, concentration, and ratio of reactants in the precipitating solution; the speed of agitation; the reaction time; and the reaction temperature.

Step 2: Washing

The precipitated silica slurry is then concentrated to form a filter cake. The product filter cake is washed to remove the salt byproduct that is produced during precipitation.

Step 3: Drying

The silica filter cake is then dried to the desired final product moisture content.

Step 4: Finishing and packaging

The dried silica is then finished to achieve the desired final product form. This can include: agglomeration or compaction into a low-dust form, or milling and classification to the required particle size distribution. The final product is packaged for shipment in small bags, big bags, or bulk trucks or railcars.

Introduction

Our reputation as a key national supplier is built upon the foundation of quality and integrity. The company has independently researched, developed and manufactured several series products including Silica Matting Agent, Matt Hardener, Fumed Silica, Zinc Stearate and Alumina.

Our product development is guided by accurate market analysis. We have successively established R&D Centers of Matting Agent, Fumed Silica, Zinc Stearate, Matt Hardener, and Alumina.Application Research centers were also created for mediums such as paints, ink, textiles, leathers and new energy materials. These Modern facilities form the very core of our development system and are staffed by a professional taskforce of technical personnel. Their contributions have yielded environmental-friendly products such as the low oil absorption UV matting agent, a compound that was specifically designed to minimize the VOC emission of paints. These Products are the building blocks of eco-friendly alternative engry solutions. Their ability to protect leather and prevent the corrosion of metals make them idea for floor coating, glass paint, and the making of woodenware.

Quanxu Technology firmly believes that technological advancement is the precursor for market performance. We have established major distribution centers in one overseas location and 3 domestic regions.

Product quality has always been at the very top of our priorities. Over the years, we have imported a number of advanced testing instuments enhanced quality control and inspection. Quanxu operates in strict adherence with all relevant safely standards. Our export products are approved by international recognized standards such as SGS and ROHS.

More than a decade of groundwork has allowed us to penetrate overseas markets in regions including Europe, the Middle East, South America, Southease Asia, Africa, Etc. We have established a long-term cooperative partnerships with international chemical mega-corporations such as Valspar and AKZONOBEL.

Through sustained growth and expansion, Quanxu Technology strives to become a world-leading supplier of chemical materials. With quality and integrity, we will create an enterprise that can withstand the test of time!!
