Purification method of high-purity quartz sand with SiO2 purity more than or equal to 99.99%

The invention discloses a purification method of high-purity quartz sand with SiO2 purity more than or equal to 99.99%, and the purification method comprises the following steps: (1) flotation-multiple flotation separation to remove feldspar particles and layered aluminosilicate mineral particle impurities; (2) high temperature activation and water quenching cooling; (3) high-temperature alkalinewashing to remove impurities; (4) high-temperature oxidation pickling to remove impurities; (5) ultrasonic washing for many times, dewatering and drying; and (6) high-temperature heating and chlorination to remove impurities. The purification method has the beneficial effects that the high-purity quartz sand with SiO2 purity more than or equal to 99.99% is obtained after raw material quartz sand with the purity of 99.5% is purified, the economic benefits of enterprises are obviously improved; a new method to remove gas, liquid and solid inclusions in quartz particles is explored; crystal transformation temperature of the quartz particles is increased to 1600 DEG C, so that structural water (hydroxyl groups), gas inclusions and liquid inclusions in crystal lattices quickly escape from the crystal lattices, and metal impurities are fully exposed, the metal impurities are removed by high-temperature chlorination, and the purity of the product is improved.

Normal-temperature purification material for removing formaldehyde and preparation method of normal-temperature purification material

The invention belongs to the technical field of purification materials, and provides a normal-temperature purification material for removing formaldehyde and a preparation method of the normal-temperature purification material. The normal-temperature purification material for removing the formaldehyde is prepared from an inorganic component and an organic component, wherein the inorganic componentis prepared from the following components in parts by weight: 1-28 parts of attapulgite, 5-30 parts of montmorillonite, 0-15 parts of sepiolite and 0-13 parts of diatomite, and the organic componentis prepared from the following components in parts by weight: 0.1-3 parts of flavan-3-ols, 1.5-7 parts of chitosan, 2-8 parts of lysine, 1-5 parts of histidine, 0.5-8.2 parts of N-cocoyl glumatic acid, 1.5-5 parts of imidazolidinone and 0.5-3 parts of polyethylene glycol. According to the preparation method of the normal-temperature purification material, an organic matter aqueous solution is added into an inorganic mixture to be stirred and subjected to still standing for layering, and a mixture is obtained after the liquid level is higher than the upper surface of a solid by 0-1 mm in a drying oven, and the obtained mixture is cooled to the room temperature firstly, then precooled for 8-12 h at minus 20-minus 30 DEG C, and finally subjected to freeze drying at minus 50 DEG C. Through thetechnical scheme, the problem that in the prior art, a purification material is low in formaldehyde removal rate is solved.

Pipe flange protection cover

The invention discloses a pipe flange protection cover and aims to solve the problems that an existing pipe flange protection cover is molded or cast through a die as required, the production cost is high, dimension adaptability is low, the existing material is not breathable, the pipe is easy to heat and expand, and accordingly the flange cover is dropped off; in addition, since the existing material is excessively heavy, the transportation cost is increased. The pipe flange protection cover is characterized in that the lower end and bottom are made of polypropylene non-woven fabric or composite leather, the upper end is made of soft material and forms an opening end in a surrounded manner, and an adjusting part used for adjusting the diameter of the opening end is arranged on the side wall. The bottom and side wall of a pipe flange protection cover body is made of the polypropylene non-woven fabric or composite leather, the cover has the advantages of breathability, environment protection, wear resistance, oil prevention, water prevention, solar radiation aging resistance and small specific gravity, the temperature in a tube is decreased effectively, the transportation cost is reduced greatly, the diameter of the opening end can be adjusted so that the cover can be adaptive to pipes with different diameters, production cost is reduced, and the unforeseen effect is achieved.
