Eight steps in our Longyan facility. Each one decides a parameter you will later read on the COA — and the last two are what customers walk through when they audit us.
Sodium silicate and acid are metered into the reactor under controlled pH and temperature — the step that sets particle size and pore structure before anything else can be adjusted.
The precipitate is filtered and washed until conductivity confirms the salts are out. Residual electrolyte is what causes downstream pH drift in a customer’s system.
Slurry is atomised into the drying tower. Inlet temperature and feed rate here determine bulk density and how the powder will later flow in a silo.
Dried agglomerates are milled to the target D50. This is where an abrasive grade and a flow-aid grade separate from the same base material.
Every lot is tested for BET surface area, oil absorption, particle size, pH and loss on drying before release — the values that appear on your COA.
25 kg bags, batch-coded and palletised. Small-batch and multi-grade consolidation are handled at this stage, not as an afterthought.
PPE, evacuation routes and area rules are covered before anyone enters production — the step auditors check exists before they check anything else.
Customers walk the reactor hall themselves. pH and temperature control are demonstrated live rather than described in a slide deck.
Four international stands, four application tracks — the same expansion you see across our six solution pages today.
Censil Silica is the silica brand of an integrated manufacturing-and-trading group. Our parent company, Longyan Shenghe Trading Co., Ltd, has been exporting since 2010; the stands below were run by the group’s materials team.
Our stand at Fi Asia focused on one question: will your powder still flow after a monsoon season? Anti-caking and carrier grades were shown side by side, with samples on the shelf and an application wall behind the meeting table.
At IE expo the demo table did the talking: raw water in, polished water out, through a column of functionalised silica-based adsorbent. Engineers stayed for the breakthrough-curve discussion.
