Embodiment 1

[0028] Embodiment 1: with 1.1Kg of pure white chemically pure powdery diatomite under 150 mesh sieves, mix gradually with 0.8Kg macromolecular protein glue solution (being 1: 0.4 is formulated by protein glue and water by weight ratio) and Stir evenly, pour into a metal sieve with a hole diameter of 1.0mm, and sieve while stirring, until all the sieves are finished; pour the sieved mixed powder into a steel mold with a diameter of 25.0CM and a height of 5.0CM, and apply vacuum pressure , then use a hydraulic press to pressurize to 2.5MPa, keep the pressure for 1 minute, release the pressure, demould, take it out, and place it on a glass plate to dry (or dry) to form a disc-shaped product with a diameter of 25CM and a thickness of 3.0CM. Embryo. Some of the surface of the plate are embossed with artistic patterns, while others are without patterns. Put the disc in a 26CM square and 4.0CM deep covered metal box, then put the metal box into the vacuum activation furnace, and pum...

Embodiment 2

[0029] Embodiment 2: mix and stir with 4.5Kg of white chemically pure powdery silica gel under 150 mesh sieves and 3.5Kg macromolecule protein glue solution (being 1: 0.45 to be formulated by protein glue and water by weight ratio) and stir, pour into In the metal sieve with an aperture of 1mm, sieve while stirring until all the materials are screened out, then pour the material into a steel mold with an aperture of 15.0CM and a height of 60CM, apply vacuum pressure, and then pressurize with hydraulic pressure To 3.0MPa, hold the pressure for 3 minutes, take it out from the mold, and it will become a cylinder. Put the cylinder into a metal barrel and cover it, then put it into a vacuum activation furnace, and pump the furnace to 2×10 3 The vacuum degree of Pa is heated to 220°C at a speed of 0.4°C / min, and the heat preservation and pressure are maintained for 5 hours. Afterwards, it is lowered to room temperature at a rate of 0.5°C / min, and then the pressure in the furnace is...

Embodiment 3

[0030] Embodiment 3: will pass through the powder diatomite of 150 mesh sieves or silica gel 5Kg, fully mix with 4.4Kg macromolecule protein glue solution (being 1: 0.5 to prepare by protein glue and water by weight ratio), stir, pass through After sieving (the diameter of the sieve hole is 1 mm), it is poured into a silicone rubber mold with a Buddha statue, vacuum suction is carried out, and then mechanical pressure is applied, and the pressure is maintained for 8 hours, and the pressure is released, demoulded and taken out, which is the Buddha statue body. Let it dry by itself or put it in a drying room for 1-5 days. Then put it into a metal barrel and cover it, then put it into a vacuum activation furnace, and raise the vacuum in the furnace to 2.5×10 within 10 minutes. 3 Pa, then raise the temperature to 200°C at a rate of 0.3°C / min, hold the heat for 6 hours, then drop to room temperature at a rate of 0.5°C / min, take out the furnace pressure to normal pressure within 20 ...

Abstract

The present invention is one kind of seamless active silica lump and its production process, regeneration method and product. The production process includes mixing white powdered silica gel or diatomite and natural or artificial transparent macromolecular protein gelatin in certain ratio, sieving, vacuum molding to form seamless silica lump, setting inside metal container with cover, vacuum heating in a vacuum furnace at (2-5)x10<3> Pa and 150-250 deg.c for 2-6 hr, cooling to room temperature at the rate of 0.4-0.6 deg.c / min and raising to normal pressure to obtain the seamless active silica lump. The seamless active silica lump may be further produced into different products as required, and the used product with saturated adsorption may be desorbed to activate. The products may be used in adsorbing harmful matter from air or liquid and have service life of several years.

Description

technical field [0001] The invention relates to a method for producing and regenerating block-shaped seamless active siliceous body with strong adsorption function and its products. Background technique [0002] In the prior art, although people have already used the adsorption function of powdered diatomite and silica gel to serve human beings, they have not been made into seamless blocks, and their application range has been greatly limited. To absorb impurities in certain liquids (such as beer), decolorize, purify, dry, etc. With the development of social economy and the improvement of the quality of life and the enhancement of human rights and environmental awareness, environmental protection has been paid more and more attention by the public. Living rooms, hotels, classrooms, offices, business buildings, entertainment places, vehicles, cabins, cabins, etc., due to toxic and harmful gases released by decoration materials, furniture, toys, cloth, etc. (such as formaldeh...
