Method used

As a kind of optional embodiment, described ferric salt adopts that weight ratio is that ferric sulfate of 1: 1 is mixed with ferrous sulfate; Adopting weight ratio is that ferric sulfate of 1: 1 mixes with ferrous sulfate , can maintain the ratio between ferrous ions and ferric ions after complexation can reach a level of 1:2, so that the joint action stage with RNx(OH)y(COOH)z can fully replace ferrous ions , and ferric ions form complexes, so as to achieve...

Abstract

The invention belongs to the technical field of disinfection, and particularly relates to an easily degradable disinfectant and a preparation method thereof, the disinfectant comprises the following components by weight: 10-25 parts of RNx (OH) y (COOH) z, 40-55 parts of sodium-method calcium hypochlorite, 10-15 parts of diatomite, 15-20 parts of potassium peroxymonosulfate, 6-10 parts of wood active carbon fiber, 2-10 parts of an active auxiliary agent, and 8-15 parts of iron salt; wherein x is 0-2, y is 0-2, z is 2-4, and R is alkyl; the method comprises the following steps: dissolving the active auxiliary agent, and adding wood carbon active fibers to prepare mixed powder; adding sodium-method calcium hypochlorite into the mixed powder, heating and stirring to prepare composite powder; adding RNx (OH) y (COOH) z into the composite powder, standing, then adding potassium hydrogen peroxymonosulfate, and preparing a hybrid powder; adding the iron salt into the hybrid powder, and then adding diatomite to prepare the disinfectant; wherein the obtained disinfectant can stably disinfect and sterilize, is degraded without residues, and is environment-friendly.

Example Embodiment

[0053] According to another exemplary embodiment of the present invention, a method of preparing a degradable disinfectant is provided, the method comprising:

[0054] The active aid was dissolved, and the xyb carbon active fiber was added, and after stirring 10-15 min, the stratification, centrifuge, stirred again, dried, and mixed.

[0055] In the mixed powder described, sodium sodium chlorate is added, and the temperature is stirred, and the composite powder is obtained.

[0056] RN x (OH) y (COOH) z In the addition of composite powder, it is allowed, then a potassium hydrogen hydrogen sulfate is added, stirred to uniform, resulting in heterozygous powder;

[0057] After adding the obtained heterozygous powder, the mixture was mixed, and then diatomaceous earth was added, and after stirring was dispersed, the powder of the disinfectant was obtained.

[0058] As an alternative embodiment, the temperature is raised to 28-32 ° C at 1-3 ° C / s.

[0059] The control temperature increased at a constant 1-3 ° C temperature to 28-32 ° C, mainly, for the intense temperature change in the hypochlorite mixing, can easily react directly to the calcium sankrate, resulting in chlorine gas, affecting product purity; When the temperature range is too high, the calcium hypochlorite is prone to directly react, generates product, affecting the effectiveness of the product; when the temperature range is too low, the gap between the hypochlorite and the mixed powder will increase the calcium chlorite. Uniform mixing is uniform, resulting in pre-use of calcium oxide, and the active aid cannot be taken to react, resulting in calcium slycate consumption, and the active auxiliaries have not reacted, so that sufficient degradation is not achieved.
