Description

A kind of manufacture method of ultra-low dew point desiccant wheel fibrous paper
Technical field
The present invention relates to desiccant wheel manufacture field, more particularly to a kind of making side of ultra-low dew point desiccant wheel fibrous paper Method.
Background technology
Rotary dehumidifier belongs to an important branch of field of air conditioning, and at present, what is developed is forth generation rotary wheel dehumidifying Machine, using advanced solid absorption technology, can be run with the air humidity adjusting of continuous-stable, big load, particularly low temperature and low humidity work - 70 DEG C of ultra-low dew point temperature is capable of achieving under condition.Dew point temperature, refers to and is keeping making not satisfying in the case that humid air water capacity is constant Reduce with humid air temperature, be down to air dry-bulb temperature corresponding when relative humidity reaches 100% and be referred to as the nonsaturated air Dew point temperature.
Desiccant wheel is a core component of dehumidifier, and it is composited by ceramic fibre carrier and adsorbent；Runner Both sides are divided into two regions by special sealing device：Processing region and regeneration zone；Pass through when the humid air of dehumidifying is needed During the processing region of runner, the water vapour of humid air is adsorbed by the adsorbent of runner, and the processed blower fan of dry air is delivered to and needed Space to be processed；And constantly the slow runner for rotating carries and tends to the water vapour of saturation and enter regeneration zone；It is anti-in renewing zone The moisture content adsorbed in runner is desorbed to the high temperature air being blown into, outdoor is discharged by blower fan, so that runner has recovered to inhale Wet ability and complete regenerative process, runner is constantly rotated, above-mentioned dehumidifying and regeneration carry out again and again, so as to ensure Runner it is continual and steady except wet condition.Wherein, the raw material fibrous paper of desiccant wheel plays decisive to the quality of desiccant wheel Effect.
But, existing ceramic fiber paper strength character is relatively poor, dehumidifies in being only used for conventional rotary formula dehumidifier The production of runner, if directly applying to the making of ultralow ultra-low dew point desiccant wheel, can cause which rotary-type in ultra-low dew point Ftracture in dehumidifier, fracture, it is impossible to reach expected effect on moisture extraction.
The content of the invention
Goal of the invention：It is an object of the invention to provide a kind of manufacture method of ultra-low dew point desiccant wheel fibrous paper, improves The toughness of fibrous paper so as to can at a temperature of ultra-low dew point normal work.
Technical scheme：A kind of manufacture method of ultra-low dew point desiccant wheel fibrous paper of the present invention, including following steps Suddenly：
(1) hygroscopic agent and Ludox are carried out into mixed grinding；
(2) defoamer, dispersant and coalescents are added to carry out slurrying；
(3) slurry that fibrous paper is put into step (2) is carried out into overlay film, obtains finished product.
Wherein, step (1) is put into hygroscopic agent and Ludox in grinder and carries out wet grinding；The grinding of wet grinding turns Speed is 1500rpm～3000rpm, and milling time is 30min～60min, and drop temperature is 15 DEG C～25 DEG C.
Wherein, in step (2), defoamer includes emulsified silicone oil, polyoxyethylene polyoxypropylene tetramethylolmethane ether, Polyethylene oxide One or more in polyoxy propanol amidogen ether, polypropylene glycerol aether；In step (2), coalescents include polyvinyl alcohol, propylene One or more in acid resin, carboxymethyl cellulose.
Wherein, step (3) obtains the continuous film layer of consistency of thickness by Best-Effort request knifing；Continuously the density of film layer is 80g/m2-140g/m2。
Beneficial effect：Compared with prior art, the present invention has following remarkable advantage：The present invention will be inhaled by Ginding process Humectant is mixed with Ludox, and is ground to superfine particle diameter, hygroscopic agent is sufficiently mixed with Ludox, and is uniformly sent out Be dispersed in slurry, finally one layer of uniform continuous film layer for having adsorption function, pliability high is covered in fibrous paper surface.Due to The protective cover quality of fibrous paper surface prepared by the method thinner, toughness is higher, so hygroscopic agent is combined more with Ludox Step up close, hygroscopic agent be uniformly distributed using the ductility of Ludox so as at a temperature of ultra-low dew point also can work well, have Effect carries out dehumidification treatments.
