The invention provides a new technology for washing and purifying superfine silicon dioxide with an applied membrane separation technology, and discloses a new method for the efficient washing and purification and the solid-liquid separation and concentration of the superfine silicon dioxide powder, which effectively improves the phenomena of long washing cycle, low efficiency and poor product quality of traditional washing methods like a plate and frame filter press and a centrifuge. The superfine substance separation technology is based on the membrane filtering effect of a porous ceramics medium, and adopts an efficient 'cross flow' filtering type, which leads the superfine silicon dioxide powder suspending liquid to be treated with sufficient washing, solid-liquid separation and realize the purification purpose of the powder. The method is an ideal method for the moment for efficiently washing and purifying the superfine silicon dioxide powder.

Artificial composite pigment and preparation method thereof

Номер: CN0102093758A
Автор: LI ZHOU, GE HESONG, LI HAO, CAI YOUXING, ZHOU LI, HESONG GE, HAO LI, YOUXING CAI
Принадлежит:

The invention discloses an artificial composite pigment and a preparation method thereof. The pigment uses natural powdered quartz (quasi-spherical silica micropowder) as matrix and uses titanium oxide crystal as a coating material, wherein the matrix is 50-70 percent of the total weight of the pigment. Through the innovation of raw materials, product and process, in the invention, a new technology to produce titanium pigment substitute product taking natural powered quartz as main raw material is developed. The titanium pigment provided by the invention has the advantage of high whiteness, low oil absorption, high masking power, good weather resistance, acid resistance and alkali resistance and low cost, and can be widely used in coating, plastics, rubber and other fields, thereby having wide application prospects.

High-purity ultra-fine torispherical silicon micro-powder prepared from natural powder quartz ore and preparation method of silicon micro-powder

Номер: CN0102120581A
Автор: LI ZHOU, GE HESONG, LI HAO, CAI YOUXING, ZHOU LI, HESONG GE, HAO LI, YOUXING CAI
Принадлежит:

The invention discloses a high-purity ultra-fine torispherical silicon micro-powder prepared from natural powder quartz ore and a preparation method of the silicon micro-powder. The preparation method comprises the following steps: by taking the cheap natural quartz ore as a raw material, adding inorganic dilueted acid which exerts the grinding aid effect in an ultra-fine grinding machine so as to prepare ore slurry, and regulating the pH of the ore slurry to 2-3; by taking a zirconia ball as a ball-milling medium, grinding for 2-4 hours in the ultra-fine grinding machine; when the power of which the particle diameter is 2mu m reaches 60%-90% in the high-purity ultra-fine silicon powder, adding reductant sodium hydrosulfite and complexing agent oxalic acid, wherein the dosage of the reductant sodium hydrosulfite is 1-2% of weight of ore powder, and the dosage of the complexing agent oxalic acid is 0.5-1-5% of weight of ore powder; and after continuing to grind for a while, washing, filtering ...
