Description
Technical field
The present invention relates to drier, be specifically related to a kind of granular drying agent for containers.
Background technology
In container transport by sea or storage process, container tends to experience ocean high humidity weather and stronger day and night temperature changes, and can produce " container rain ", and the water of this liquid state can produce serious influence to the external packing of goods in the container or goods.
Nowadays, Container shipping drier main component is with Concave-convex clay rod, montmorillonite and calcium chloride, it is that to adopt merely calcium chloride be primary raw material that the higher drying agent for containers of a kind of hydroscopicity is arranged, although the hydroscopicity of calcium chloride is high, but generate aqueous water after the moisture absorption, be easy to from the drying agent for containers packaging material, leak out, pollute the external packing of the interior goods of container and container or goods.
China Patent Publication No. CN 101637691 A, open day on 02 03rd, 2010, name is called " a kind of preparation method of container drier ", disclose " a kind of preparation method of drier of counter special use, it is that the converted starch of 60%～80% calcium chloride and 20%～40% is packed into to seal in Du Pont's paper bag and got final product with mass percent; Because the moisture in the counter can enter in the packaging bag by Du Pont's paper bag and contact with calcium chloride and converted starch, calcium chloride has good water sorption, moisture content can be solidified as for converted starch, so this product moisture sorption effect is good, can guarantee effectively that the goods in the counter is in drying regime; Because the Vapor adsorption of this product is effective, and cost of manufacture is low, thereby is widely used on the counter drying ".
The weak point of above-mentioned patent is to use " converted starch " that moisture content is solidified in this technology, directly have influence on the practical effect of container drier, because the water content of converted starch is 15%～21%, the amount that converted starch self can solidify the moisture content of calcium chloride absorption is also little.
Adopt the container drier of 100 grams to calculate, charge ratio is 60% calcium chloride and 40% converted starch, 60 gram calcium chloride in the container drier of 100 grams can adsorb the interior moisture of counter 〉=60 grams, and the converted starches of 40 grams can't solidify the moisture of 60 grams.
The converted starch purchase cost is higher, is unfavorable for applying.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of granular drying agent for containers that hydroscopicity is high and the moisture that adsorbs can be cured that has is provided.
Granular drying agent for containers is comprised of dolomite Concave-convex clay rod, sulfuric acid, high sticking Concave-convex clay rod powder, calcium chloride and high hydroscopic resin.
The production method of granular drying agent for containers: first the dolomite Concave-convex clay rod is carried out acidification, mix with the sticking Concave-convex clay rod powder of height again, jointly pulverize with calcium chloride and high hydroscopic resin after compressing tablet and the heat treatment, be packaged as granular drying agent for containers.
The content of calcium oxide 〉=24% in the dolomite Concave-convex clay rod, magnesian content 〉=12%; Alundum (Al2O3) content 〉=8%,
With the sulfate mixtures such as generating portion calcium sulfate, magnesium sulfate and aluminum sulfate after the acidified processing of dolomite Concave-convex clay rod, calcium sulfate, magnesium sulfate and aluminum sulfate all have higher wettability power, again the dolomite Concave-convex clay rod after the acidification is carried out activation heat treatment, greatly improved the moisture sorption effect of dolomite Concave-convex clay rod.
High sticking Concave-convex clay rod water imbibition is strong, and tool viscosity and plasticity are conducive to the bonding between the raw material when wet, improve adsorption capacity and the granule strength of granular drying agent for containers.
High sticking Concave-convex clay rod powder refers to get 28.0g Concave-convex clay rod powder sample, add in the suspension cup of homogenizer, add again 372g water, the suspension cup is placed on the homogenizer, under 11000 rev/mins rotating speed, stirred 20 minutes, to pour in the beaker of 250ml through the high-speed stirred sample suspension again, the viscosity of using NDJ-1 type rotation viscometer to test its suspension, the Concave-convex clay rod powder of tested viscosity value 〉=2200 mPas is high sticking Concave-convex clay rod powder.
Calcium chloride is soluble in water, and hygroscopicity is extremely strong, is exposed in the air very easily deliquescence, and calcium chloride can absorb the moisture greater than own wt from air, and the present invention selects anhydrous calcium chloride, the content of calcium chloride 〉=90%.
The water absorption of high hydroscopic resin is large, can reach hundreds of times even thousands of times of sole mass, can generate gel after the suction within the several seconds, and water-retaining property is strong.High hydroscopic resin is used for the present invention can rapid the expansion be converted into the gel solid body with the water of granular drying agent for containers absorption, this gel solid body is called solid water, even under low temperature, pressurized conditions, also be difficult for dehydration, good stability to light, heat, cold-peace soda acid, has good biodegradability, the grain fineness of the high hydroscopic resin that the present invention selects≤1.0 millimeter.
The present invention is achieved by following technical proposals:
1, the batching of granular drying agent for containers is comprised of following component by weight percentage: the Concave-convex clay rod 10～35% after the heat treatment, calcium chloride 64～89% and high hydroscopic resin 0.01～3%;
