Description
Technical field
The invention belongs to drier technical field, more particularly to a kind of concave convex rod antirust drier.
Background technology
Drier is the most frequently used material of industrial and civilian damp-prrof packing, and existing drier commodity have（1）Silica-gel desiccant：
Main component is silica, and granular or pearl is process by purification by natural minerals.（2）Ore deposit drier living：Outward appearance shape
Shape is grey bead, and adds calcium chloride in clay to improve moisture absorption, moisture absorption in environment of the optimum below 50 DEG C.When
Temperature is higher than 50 DEG C, and " discharging water " degree of clay is just more than " water suction " degree.（3）Molecular sieve desiccant：It is it is artificial synthesized and
There is the desiccant product of stronger adsorptivity to hydrone.The pore size of molecular sieve can be controlled by the difference of processing technology,
Except adsorbing aqueous vapor, it can also adsorb other gases.But hydroscopicity is low, environmental protection is poor（Non-degradable）.（4）Montmorillonite is dried
Agent：Also known as bentonite, amargosite, heated drying, the clay crushed are mainly characterized by nontoxic, degradable, but moisture pick-up properties is low
In silica-gel desiccant.（5）Fiber desiccant：First fiber desiccant that weighs be it is exquisite through special process by pure natural plant fiber and
Into although Product Safety is high, processed complex cost is higher.As Chinese invention patent 03116717.9 discloses a kind of drying
Agent its using clay as primary raw material, it is 10-50%, attapulgite 90-50%, except main body that drier main body, which contains calcium-base bentonite,
In addition, also containing polyvinyl alcohol 0.2-0.6%, polyacrylamide 0.6-0.2%, calcium chloride 10-30%.Chinese invention patent Shen
92108509.5 a kind of efficient drying agent and preparation method thereof please be disclosed, belong to the solid absorbent of dry gas, it is with swollen
Swollen perlite is carrier, is combined with magnesium perchlorate and can add metallo-chelate as colored indicator, perlite, magnesium perchlorate
Weight ratio with metallo-chelate is 1: 1: 0.001 to 1: 5: 0.05, is made by thermal dehydration in mixing and normal pressure and vacuum
.
But the problem of generally existing hydroscopicity is relatively low in now widely used drier, such as silica gel, montmorillonite, calcium oxide
Hydroscopicity below 40%, added in montmorillonite, concave convex rod a certain amount of calcium chloride hydroscopicity also only 100% with
Under.Although it can reach 100% or so in fiber desiccant hydroscopicity, cost is higher.In recent years, with science and technology
Fast development, it is more and more high to the performance requirement of metal spare and accessory parts mineral agent, match somebody with somebody in the market for metal zero
There is the shortcomings that hygroscopicity is poor, and drying property is bad in the mineral agent of part, cause the easy burn into of metal spare and accessory parts to get rusty,
The market demand can not be met.
