Abstract
The invention relates to an impregnation process for improving the pressing performance of recombined materials, and belongs to the technical field of artificial plate manufacturing. The recombined materials are artificial plates which are formed by impregnating, pressing and cementing prefabricated small-strip plant materials. The impregnation process adopts a technique of mixing talcum powder of certain proportion in a glue solution, so that the surfaces of the recombined materials are uniformly adhered with a layer of talcum powder which is used as lubricating agent. The impregnation process further adopts a secondary impregnation technique, so that the concentration of the glue solution and the proportion of the talcum powder are controlled easier. Through the application of the impregnation process, the liquidity of the recombined materials inside a pressing and forming mould can be improved, thereby remarkably reducing gaps inside the recombined materials. While the product quality is improved, the pressure requirements for pressing are reduced, the material utilization rate is improved, and the internal stress of the recombined materials is reduced, so that the recombined materials are not easy to deform; and simultaneously, the loss and power consumption of a press for pressing the recombined materials are remarkably reduced.

(2) impregnation is that position adjacent is established the secondary dipping pond in addition in the soaking pond for the second time; Be provided with agitating device in the pond; In said secondary dipping pond, inject with the used identical glue of impregnation for the first time after, the superfine talcum powder and the continuous stirring that add by glue weight calculating about 5% in the pond become uniform suspendible glue.The raw material that the first time, impregnation finished drained a little promptly immerse the secondary dipping pond, and make glue fully mobile in said reorganization material raw material, evenly adhere to said superfine talcum powder in the hope of said reorganization material raw material surface.Make a kind of straightforward procedure that said suspendible glue fully flows in said reorganization material raw material be: said reorganization material raw material just is lifted out the glue liquid level after the submergence in said suspendible glue, and then submergence to rise once more, promptly accomplish impregnations for the second time 5 times repeatedly.
Said secondary dipping pond does not need often to adjust gelatin concentration, if every day impregnation begin preceding and situation that talcum powder fully precipitates under, the production technology adjustment gelatin concentration original by reorganization material production firm gets final product.Glue density will continuously stirred and often measure in said secondary dipping pond when impregnation, the content that shows said reorganization material when glue density should in time add superfine talcum powder and stirs smaller or equal to 3% the time.Said secondary dipping pond is also noted that the variation of pH value when impregnation, its control range should with said first time impregnation identical.The granularity of said superfine talcum powder should be at 1250 orders or thinner.
Can produce significant foam because of stirring in the said secondary dipping pond, thereby the influence operation.Therefore said secondary dipping pool side is provided with high-pressure sprayer, and said high-pressure sprayer can spray powerful water smoke, is used to eliminate foam.
What the present invention was further perfect is: evenly adhere on the whole length of said reorganization material raw material in order to make glue and talcum powder, after the said immersing glue process completion second time, should it directly not left standstill and drain; And after should treating that said reorganization material raw material tentatively drains, again it is turned around up and down, leaves standstill, further drain.
Beneficial effect: owing to adopt technique scheme; The present invention utilizes talcous lubricity, has improved the flowability of reorganization material in press-moulding die, has improved product quality, raw material availability and mechanical life; Have tangible energy saving, have better operability simultaneously.The production and the application of material can promote to recombinate.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is impregnation pond and the sketch map that drains groove in the embodiment of the invention.Among the figure:
1---the soaking pond
2---the secondary dipping pond
3---drain groove
4---mixer
The specific embodiment
1. the preparation before the beginning impregnation: in soaking pond and secondary dipping pond, inject the recombinate capacity glue of material raw material of fully submergence, measure its concentration (generally measuring), pH value must meet original technological standards with densimetry; Start secondary dipping pond mixer, add by the superfine talcum powder (1250 orders or thinner) of glue weight calculating about 5% in the pond and treat that it stirs; In glass container, hold glue that stirs and the glue density of measuring this moment immediately, the density range that records in the laboratory before should meeting.Secondary dipping pond mixer can not stop in whole immersing glue process, otherwise superfine talcum powder can precipitate very soon.
2. impregnation for the first time: hang in the soaking pond to reorganization material raw material with driving (crane), abundant submergence and timing.
3. drain behind the impregnation for the first time: the impregnation time arrives, and hangs a reorganization material raw material on the liquid level of soaking pond with driving, hangs the material raw material of recombinating on the liquid level of secondary dipping pond when having only a small amount of glue sound of rain pattering in the material raw material of waiting to recombinate.
4. impregnation for the second time: hang in the secondary dipping pond to a reorganization material raw material with driving, promptly hang on the liquid level after the abundant submergence, and then submergence is sling 5 times repeatedly once more.
5. drain behind the impregnation for the second time: hang a reorganization material raw material on the liquid level of secondary dipping pond with driving, when having only a small amount of glue sound of rain pattering in the material raw material of waiting to recombinate hang the material raw material of recombinating and drain on the groove.
6. turn around to leave standstill to drain: with driving or be aided with other machinery and turn around reorganization material raw material up and down to place, drain draining to leave standstill on the groove.Drain the glue that flows out in the groove and should flow into the secondary dipping pond.
7. the adjustment of gelatin concentration in the immersing glue process: along with the increase of impregnation number of times; In the soaking pond not only the glue total amount reducing; And because large quantity of moisture infiltrates reorganization material raw material inside, so the concentration of glue is also rising, so will in the soaking pond, replenish lighter glue and water.So the secondary dipping pond is because what immerse is that dry reorganization material raw material gelatin concentration in the long time does not have big variation, and along with the inflow glue total amount that drains glue in the groove is also increasing gradually.Unnecessary part should in time be extracted out, and deposition is fallen talcous glue can add to the soaking pond; The talcum powder that precipitates can add to the secondary dipping pond.
8. the adjustment of extra fine talc powder content in the immersing glue process: along with the increase of impregnation number of times, the extra fine talc powder content reduces gradually in the secondary dipping pond.Therefore in whole immersing glue process, to often measure glue density, often add superfine talcum powder.The content of superfine talcum powder in glue is remained in 3% to 5% the scope.
9. the adjustment of glue pH value in the immersing glue process: because reorganization material raw material has certain acidity; The reorganization material feedstock acidity of particularly handling through charing is bigger; So for using the glue that causes gelatin phenomenon easily; For example some adds the modified soluble phenol glue of urea, melamine etc. when synthetic, when impregnation, must often test pH value.When finding that pH value has obvious declines, for example pH value drops at 10 o'clock from 11, should in time add sodium hydroxide solution and adjust pH value.
10. eliminate the foam operation in the immersing glue process: can produce foam because of stirring in the secondary dipping pond, foam gathers more and more thereby the influence operation.Therefore when foam is too many, aim at foam, spray powerful water smoke, eliminate foam with high-pressure sprayer.
More than basic principle of the present invention and principal character and advantage of the present invention have been explained in explanation.The technical staff of the industry should understand, and the present invention does not receive the restriction of above-mentioned instance, and principle of the present invention is just explained in the description in above-mentioned instance and the specification.Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the claimed scope of the invention.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
