Embodiment 2

[0043] Embodiment two: the technical solution adopted in this embodiment is: it comprises main material and auxiliary material, and the mass percentage of both is main material: auxiliary material is 1:0.3; The mass percentage of described main material is composed of: cotton wadding 45 %, peat moss 30%, tea stalk 15%, and straw 10%; the mass percentage of the auxiliary materials is composed of: calyx 70%, activated carbon powder 10%, and nano rubber powder 20%.

[0044] The manufacturing process of the present invention is as follows:

[0045] 1. Wash the sphagnum moss with pure water five times, use potassium permanganate (volume fraction 1:3000) to disinfect the cleaned sphagnum moss once, and then use hydrogen peroxide to disinfect twice, each time for 20 minutes;

[0046] 2. Wash the tea stalks and straws with pure water for 6 times, and then send them to an oven for drying. The drying temperature is 60°C, and the drying time is 10 hours;

[0047] 3. Send the sterilized ...

Embodiment 3

[0055] Embodiment three: the technical scheme adopted is: it comprises main material and auxiliary material, and the mass percentage of both is main material: auxiliary material is 1:0.3; The mass percentage of described main material is composed of: cotton wadding 50%, peat 30% moss, 10% tea stalks, 10% straw; the mass percentage of the auxiliary materials is: 75% calyx, 15% activated carbon powder, and 10% nano rubber powder.

[0056] The manufacturing process of the present invention is as follows:

[0057] 1. Wash the sphagnum moss with pure water four times, use potassium permanganate (volume fraction 1:5000) to disinfect the cleaned sphagnum moss once, and then use hydrogen peroxide to disinfect twice, each time for 10 minutes;

[0058] 2. After washing the tea stalks and straws with pure water for 8 times, send them to an oven for drying. The drying temperature is 80°C, and the drying time is 9 hours;

[0059] 3. Send the sterilized peat moss in Step 1 into an oven for...

Abstract

The invention provides a desiccant and a preparation technology thereof, and relates to the technical field of desiccants. The desiccant comprises main materials and auxiliary materials, and the mass percent of the main materials to the auxiliary materials is 1:0.3; the main materials comprise, by mass, 40%-60% of cotton wadding, 20%-40% of sphagnum, 10%-20% of tea stems and 5%-10% of straw, and the auxiliary materials comprise, by mass, 50%-80% of persistent calyxes of Chinese lantern plants, 10%-20% of activated carbon powder and 10%-20% of nanometer adhesive powder. The desiccant is high in water absorption, even when a human body makes contact with the desiccant, burning or poisoning cannot occur, the processing technology is simple, and manufacturing is easy.

Description

technical field [0001] The invention relates to the technical field of desiccants, in particular to a desiccant and a preparation process thereof. Background technique [0002] A desiccant is a substance that can remove part of the moisture in a wet substance. Such as calcium sulfate and calcium chloride, etc., are dried by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, are dried by physically adsorbing water. Moisture control is closely related to product yield. In terms of food, under proper temperature and humidity, bacteria and mold in food will multiply at an alarming rate, causing food to spoil, causing dampness and discoloration . Electronic products can also cause metal oxidation due to high humidity, resulting in defects. The use of desiccant is to avoid the occurrence of defective products caused by excess water. [0003] Physically adsorbed desiccants are suitable for preventing moisture in instruments, me...
