Abstract
The invention relates to an integrated powder modification production process which comprises the following steps of: 1, producing 325 meshes of raw materials by using a 5R Ramon mill; 2, additionally assembling a heating ejector in a two-third position of a feeding box of an air-current mill before the raw materials enter the air-current mill; 3, selecting a modifier according to the modification standard; 4, adding 1.5% to 2% of a coupling agent into the ejector and determining the ejection quantity; 5, starting the injector when the material level in the feeding box reaches two thirds; 6, evenly spraying the coupling agent on the surfaces of the raw materials through the heating ejector along with the work of the air-current mill; 7, smashing the raw materials with the coupling agent in the air-current mill to form modified powder; and 8, screening qualified products to enter a product box, performing compression packing on the products and bagging the products, thereby obtaining the qualified product. As the production process provided by the invention is adopted, the preparation process of ultrafine powder is simplified; the powder can be prevented from being subjected to agglomeration or surface passivation after ultrafine smashing.
Description
Technical field
The present invention relates to split scientific and engineering field, particularly relate to powder-modified integral manufacturing technique.
Background technology
Powder is carried out super-refinement and surface modification treatment, and the chemical reactivity that can improve powder is beneficial to the synthetic of material, and the interface affinity of modification split is conducive to the mechanical property of packing material; The various cohesive force in regulation and control minute surface are conducive to the dispersion of powder and use; Obtain powder surface specific physical performance and be conducive to the functional powder preparation.Therefore, the super-refinement of powder and surface modification are the important means of high performance material preparation process, also are the important contents of novel material, novel process and new product development.
The preparation method of existing ultrafine powder modified powder mainly is the technique that adopts elder generation, ran on foot in rear minute, that is, and and first superfine grinding, rear surface modification.This technique not only production process is complicated, and powder after superfine grinding since surfactivity greatly improve and cause reuniting or owing to other particles such as water molecules in the absorbed air make the powder surface passivation, bring difficulty to follow-up surface modification.
Summary of the invention
The objective of the invention is the problem for above-mentioned prior art existence, and a kind of powder-modified integral manufacturing technique is provided.
The technical scheme that adopts is:
Powder-modified integral manufacturing technique is characterized in that comprising following production technique:
1) produces 325 order raw materials with five R thunders illiteracy;
2) raw material is before entering airflow milling, adds the injector of heating at 2/3rds places of the charging box of air-flow;
3) by modification Standard Selection properties-correcting agent;
4) coupling agent with 1.5-2% adds in the injector and definite emitted dose;
5) when material level reaches 2/3rds in the charging box, injector starts;
6) with the work of airflow milling, the injector of heating is sprayed at coupling agent the surface of raw material equably;
7) enter to pulverize in the airflow milling with the raw material of coupling agent and make the powder of modification;
8) powder of modification enters in the separating machine, filters out qualified product and enters the product hopper, and through compression packing, qualified product are made in pack.
Above-mentioned properties-correcting agent is selected silane coupling agent
The present invention compared with prior art has the following advantages:
1, overcome in the existing superfine powder preparation process, elder generation's superfine grinding, the shortcoming of rear surface modification proceed step by step, superfine grinding and surfactivity are finished in the integrated apparatus of a step process simultaneously, and this has not only simplified the preparation technology of superfine powder, and, can prevent powder after superfine grinding because surfactivity improves greatly, and cause reuniting or because powder surface passivation during other particles such as water molecules in the absorbed air brings difficulty for follow-up surface modification.
2, in superfine modified Crushing with Jet Mill, add properties-correcting agent, not only can realize the modification to powder, and in time balance is truncated formed unsaturated one-tenth bonding force because pulverizing causes the particle surface chemical bond, powder is pulverized under good dispersion state, simultaneously, properties-correcting agent has grinding-aid effect usually, but Effective Raise superfine grinding efficient.
3, raw material has improved the dispersed and mobile of split after pulverizing by airflow milling greatly, cooperates with superpolymer and can improve mechanical property and mechanical property.The application range of modification powder and the economic benefit of enterprise have been improved.
Embodiment
Embodiment
Powder-modified integral manufacturing technique specifically comprises following processing step:
1), to pulverize used powder be brucite in modification, with five R thunders illiteracy brucite powder is broken into 325 orders as raw material;
2), raw material before entering airflow milling, add the injector of heating at 2/3rds places of the charging box of air-flow;
3), properties-correcting agent is selected silane coupling agent;
4), 2% silane coupling agent is added in the injector, the emitted dose of silane coupling agent is set as the 15ml/kg powder;
5), when material level reaches 2/3rds in the charging box, injector starts;
6), with the work of airflow milling, the injector of heating is sprayed at coupling agent the surface of raw material equably;
7), enter to pulverize in the airflow milling with the raw material of silane coupling agent and make the magnesium hydroxide ultrafine powder of modification;
8), the magnesium hydroxide ultrafine powder of modification enters in the separating machine, filters out qualified product and enters the product hopper, through compression packing, qualified product are made in pack.
