Problems solved by technology

The existing method of refining quartz powder for cosmetic production is relatively cumbersome and complicated, and it usually uses sulfur dioxide, sodium sulfite, sulfur, chlorine dioxide and other products for bleaching. These products contain certain toxicity, unpleasant smell, and are irritating to the skin. It is not suitable for the production of cosmetics because of its high sensitivity. Therefore, we propose a method for continuously refining quartz powder for cosmetic production to solve the above problems.

Embodiment 1

[0018] The present embodiment proposes the method for continuously refining quartz powder for cosmetic production, comprising the following steps:

[0019] S1: Select high-quality quartz stone ore;

[0020] S2: Smaller stones are processed by a stone crushing machine, and the small stones are then rolled into sand particles by a stone roller. During the rolling process, water is continuously added, and the water carries the sand particles into the sedimentation tank, and a solution containing benzoyl peroxide is added. Remove the yellow-brown skin on the surface of the raw ore;

[0021] S3: transport the sand in the sedimentation tank into the drying room to be baked into dry sand, and then sieve through the vibrating screen. The diameter of the sieved dry sand is 120 μm. During the screening process, use magnet bars and magnets to remove iron;

[0022] S4: Transfer the sieved fine dry sand into the reaction kettle, and evenly add a small amount of benzoyl peroxide crystals, ...

Abstract

The invention discloses a method of continuously purifying quartz powder for production of cosmetics, which includes the following steps: S1) selecting high-quality quartz stone ore; S2) crushing thequartz stone ore into smaller stone materials through a stone crusher, and grinding the smaller stone materials into sand granules through a stone grinder, wherein water is continuously added during the grinding process, so that water, bringing the sand granules, flows into a settling tank so as to remove a yellow-brown skin on surface of the raw ore; S3) delivering the sand granules in the settling tank to a roasting chamber to roast the sand granules into dry sand granules, and sieving the dry sand granules via a vibrating sieve, wherein iron removal is carried out via a magnet bar and a magnet grate during the sieving process; S4) moving sieved fine dry sand granules to a reaction kettle, uniformly adding a less amount of benzoyl peroxide crystal, and uniformly stirring and mixing the components for 15-30 min at 80-120 rpm, during stirring, proper amounts of water and perlite powder are added. The method has reasonable design, is simple and low-cost, and is low in irritation on skinon the basis of ensuring a bright white color of the quartz powder, and is suitable for production of cosmetics.

Description

technical field [0001] The invention relates to the technical field of cosmetic production, in particular to a method for continuously refining quartz powder for cosmetic production. Background technique [0002] There are many kinds of quartz powder, some are specially used for waterproof coatings, some are specially used for casting coatings, some are specially used for tunnel coatings, and there are also ultrafine quartz powder and refined quartz powder. Quartz powder is generally a white amorphous powder with a relative density of 2.319-2.653 and a melting point of 1750°C. Generally, products with a fineness below 120 mesh (less than 120 mesh) are called quartz sand, and products with a fineness of more than 120 mesh are called quartz powder. After absorbing moisture, it forms aggregated fine particles with high insulation properties, insoluble in water and acid; soluble in caustic soda and hydrofluoric acid. It does not decompose at high temperature, has water absorpt...
