[0031] A kind of micronano shell water body disinfectant can be micronano shell powder, and its preparation method comprises the following steps:
[0032] Step 1, cleaning treatment: take the shells to remove the meat, rinse the internal residual meat and surface dirt with clean water, and obtain the cleaned shells.
[0033] The shell is one or more of mussels, triangular sail clams, pleated crown mussels, white jade shells, pearl oysters, luminous shells, oysters and the like.
[0034] Step 2, pickling treatment: the shell after cleaning with acid treatment, the concentration of acid is 2-10wt% (such as 2.5wt%, 3wt%, 3.5wt%, 5wt%, 6wt%, 7wt%, 8wt%, 9wt% Or 9.5wt%), preferably 5% acid solution to remove the residue on the surface, to obtain the shell after pickling.
[0035] The acid selected in this step is one or more of inorganic acids such as hydrochloric acid, sulfuric acid, and nitric acid.
[0036] Step 3, drying treatment: put the pickled shells into an electric blas...
Embodiment 1
[0046] This embodiment is a preparation method of micro-nano shell powder.
[0047] (1) Cleaning: take the mussels to remove the meat, rinse the internal residual meat and surface dirt with clear water, and obtain the shells after cleaning.
[0048] (2) Pickling: using a hydrochloric acid solution with a concentration of 5 wt% to remove residues on the surface of the washed shells to obtain pickled shells.
[0049] (3) Drying treatment: put the pickled shells into an electric blast drying oven and dry at 110° C. for 1.0 hour to obtain dried shells.
[0050] (4) Burning and crushing treatment: place the dried shells in a muffle furnace, burn them at 1000°C for 3.5 hours, then pulverize the burnt shells with a pulverizer, and pass through the sieve obtained by 150 mesh molecular sieves. The object is shell coarse powder.
[0051] (5) Nano treatment: Use a nano grinder to further pulverize the shell coarse powder to obtain micro-nano shell powder with a particle size of 5-25 μm...
Embodiment 2
[0053] The preparation method of the micro-nano shell powder of this example is the same as that of Example 1, except that the igniting temperature in the burning and crushing process is different from that of Example 1. In this embodiment, the firing temperature is 1150°C.
