To bed spray drying equipment, spray tower EAT is set as 90 DEG C, and fluidized-bed temperature is 55 DEG C.By adjusting material flow
Amount so that spray tower leaving air temp is 45 DEG C.
(6) material screening：By the dried material of fluidized bed with spraying by 50~60 mesh sieves point, that is, obtain naphthalene or camphor is micro-
Capsule product.
Second step：The naphthalene or camphor microcapsules that the first step is obtained, which are coated on archival paper, just can obtain durable mothproof archives
Paper.
The present invention compared with prior art, extends the volatilization time of naphthalene or camphor, extends service life, it is not necessary to people
For placing camphor balls, mothproof effect is good, and can be applied to a variety of needs mothproof book printing paper or archival paper, has a wide range of application.
Embodiment
In the present invention, aqueous phase first is made in wall material, and the core oil phase liquid made is pumped into aqueous phase by peristaltic pump,
This mode of operation is advantageous to improve the efficiency and uniformity of embedding, embeds uniform naphthalene or camphor microcapsules to obtain, improves
The releasing effect and storage stability of naphthalene or camphor.Therefore the present invention is dried using fluidized bed with spraying, by spray tower EAT
For 90 DEG C, fluidized-bed temperature is 55 DEG C.By adjusting mass flow so that spray tower leaving air temp is 45 DEG C.
The dosage of wall material, emulsifying agent and water is respectively 60~90 parts of wall material according to parts by weight in such scheme, emulsifying agent 1
~2 parts, 60~90 parts of water.
It is described as preferable in order to effectively control the release of naphthalene or camphor and improve its embedding rate in such scheme
Wall material is maltodextrin, malt syrup, converted starch, Arabic gum with any ratio mixing.Wherein be preferably malt syrup and
