Description

A kind of fiber drying agent

Technical field

The utility model relates to a kind of fiber drying agent, relates in particular to a kind of fiber drying agent of nonionic.

Background technology

Present known fiber drying agent all is to be dried by the aqueous solution of fibrous material dipping hygroscopic salt to make again.This type of hygroscopic salt comprises: calcium chloride, magnesium chloride, potassium chloride, sodium chloride, calcium bromide, magnesium bromide, KBr, halide such as sodium bromide.In the hygroscopic desiccation process, hygroscopic salt can discharge a large amount of Cl because of the moisture absorption deliquescence ^-, Br ^-Ion and Ca ²⁺, Mg ²⁺Deng metal ion.When contacting with dry object, halogen ion (Cl wherein ^-, Br ^-) can accelerate the corrosion of metallic article; Metal ion (Ca such as calcium magnesium ²⁺, Mg ²⁺) also can impel Oxidation of Fat and Oils and produce gas beastly.This has all caused irreversible destruction to dry object.

Summary of the invention

In order to overcome above-mentioned defective, the utility model provides a kind of fiber drying agent that does not contain the nonionic of hygroscopic salt.

Fiber drying agent of the present utility model, the rete that it comprises the fiber carrier layer, is connected the active principle layer of fiber carrier laminar surface and covers the active principle laminar surface.

Wherein, described fiber carrier layer is that fiber sheet or other have card, the plate of fibre structure, as nonwoven, film etc.

One or more mixtures in silica gel, activated silica, zeolite and the montmorillonite that described active principle layer is a powdery form together by the adhesive high pressure is bonding.

Wherein, described rete is non-Breathable films or Breathable films, as PE, PP, PET, PVC, PS film etc.Described ventilated membrane can be making hole film.

Drier integral body of the present utility model can be made into the thin slice of random geometry, or makes stereochemical structure by deep processing.Thin slice can be triangle, quadrangle, or the shape of rule such as circle, or other irregular shapes; Stereochemical structure can be the structure of rules such as spheroid, cylinder, cone, square, cuboid, or other irregular stereochemical structures.

Drier of the present utility model, effective component layers that can bond in the carrier layer both sides further, can also be added rete on the described active principle layer.

What fiber drying agent of the present utility model was adopted is that silica gel, activated silica, zeolite, montmorillonite etc. have the active principle of the material of microcellular structure as drier, and carry out physical absorption by the microcellular structure of this type of material, be different from the chemisorbed of conventional hygroscopic salt.In process, need not as the conventional fibre drier, earlier hygroscopic salt is mixed with the aqueous solution, by the aqueous solution of fiber carrier dipping hygroscopic salt, oven dry makes again.But directly be bonded on the carrier by high pressure and the adhesive active principle with powdery, whole process does not have moisture and introduces, and need not pass through stoving process, greatly reduces energy consumption, and minimizing is to the pollution of environment; Since adopt be have the material of microcellular structure and non-hydroscopic salts as the active principle of drier, therefore in the process of using, can not discharge a large amount of harmful ions, fundamentally solve the harm of ion existence dry object because of the moisture deliquescence in the absorbed air; The utlity model has good dry moisture absorption and regenerability in addition, Environmental Safety more, can be according to dissimilar needs, drier is processed into the thin slice of random geometry, as circular, square, triangle, strip etc., perhaps other are irregularly shaped, or make cylinder by deep processing, three-dimensional shapes such as cube perhaps are other irregular stereochemical structures.This invention product can be applied to industries such as food, medicine, electronic instrument, instrument widely.

Introduce fiber drying agent of the present utility model in detail below in conjunction with accompanying drawing.

The specific embodiment

As shown in Figure 1, drier of the present utility model comprises fiber carrier layer 1, is connected the

active principle layer

2,3 of fiber carrier laminar surface and covers the rete 4,5 of active principle laminar surface.

Described fiber carrier layer 1 is that fiber sheet or other have card, the plate of fibre structure, as nonwoven, film etc.

Described active principle layer the 2, the 3rd is by tiling certain thickness (200 orders～18 orders of 0.1mm～the 10mm) (granular colloidal silica of 0.074mm～1mm), activated silica, zeolite, one or several mixtures form by adhesive and pressure binding on carrier again in the montmorillonite.

Described rete 4,5 is non-Breathable films or Breathable films (as, making hole film), as PE, PP, PET, PVC, PS film etc.

As illustrated in fig. 1 and 2, in an embodiment of the present utility model, described fiber drying agent integral body is certain thickness thin slice, and sheets of fibres shown in Figure 2 can further be cut to circle, quadrangle, and triangles etc. perhaps are that other are irregularly shaped.

As shown in Figure 3, in another embodiment of the present utility model, described fiber drying agent is made into solid figure by deep processing, as cylindricality, fiber carrier layer 1 inside and outside two surface of described drier all are bonded with

active principle layer

2,3, and the active principle laminar surface is coated with rete 4,5 respectively.

Fig. 4 shows a kind of preparation method's of fiber drying agent of the present utility model flow chart, and as shown in the figure, gluing on fiber carrier is tiled in the carrier layer surface equably with active principle earlier, forms effective component layers; The process equipment for coating film pressurizes again, heating is overlying on rete on the active principle layer.And then the another side of fiber carrier is carried out the processing of the same manner.

Fig. 5 shows the another kind of preparation method's of fiber drying agent of the present utility model flow chart, as shown in the figure, active principle and solid fusion glue are tiled in the fiber carrier surface after the mixing uniformly, by equipment for coating film pressurization, heating makes it to be bonded together, simultaneously rete is overlying on the active principle layer.And the another side of fiber carrier is carried out the processing of the same manner.

In other embodiment of the present utility model, described drier integral body can be made into other erose thin slices, also can be processed into other rule or irregular stereochemical structures, as the structure of rules such as spheroid, cylinder, cone, square, cuboid, or other irregular stereochemical structures.
