Description

 Preparation method for improving quality performance of fiberboard  

The invention relates to the manufacture of finished fiber products, and more particularly to a preparation method which can improve the quality properties of the fiberboard.

According to the prior art, the manufacture of fiberboards, whether it is a "long fiber substrate" or a "short fiber substrate" as the main structure of the fiberboard, does not deviate from the so-called "dip bathing method". It is also known as the impregnation method, which mainly uses a "pre-dip tank" to pre-inject a variety of organic or inorganic components "mixed dip" according to the characteristics of the sheet material required for production, and then rolls the whole bundle of "fiber substrate". The winding operation is sequentially output, and the "fibrous substrate" is clamped, pulled, and pulled by various preset "drive rollers", and the flow is first brought down into the "prepreg" and accepted by the "mixing" "Submerged" submerged wet impregnation operation, the "fibrous substrate" is quickly absorbed and covered in the "mixed dip" by the loose space of its own fibrous structure; and then continues to use most "drive rollers" to pull the traction, and will The "impregnated fiber substrate" is brought back to the "pre-dip tank" and finally pulled and transported to a "baking device" for heating to cure the "impregnated fiber substrate". Finally, By a "cutting device" cut into the desired size of the foot "fiberboard finished."

Because fiberboard has the advantages of light weight and is popular among the public, it has been widely used in building materials in recent years. However, according to the above-mentioned conventional process, the "fiber sheet finished product" produced by the company often finds "uneven thickness". Missing; and in the strength test of products, there are also serious shortages of quality defects. This situation is especially true when the producers of "short fiber" with lower unit price are adopted. After continuous research and experiment, the applicant finally researched The disadvantage of the conventional drawback is that the above-mentioned fibrous substrate is dragged and advanced during the impregnation operation, and the fibrous structure is continuously displaced and stretched, especially the longer the impregnation time, the more obvious, the "fibrous substrate" After absorbing the "mixed dipping", the weight of the fiber itself makes the structure looser and easier to disintegrate; in other words, the "impregnated fiber substrate" has a large increase in the axial tensile force and surface friction resistance during the front end pulling operation, originally The fibers with weaker support structure are easily pulled and deformed, and the thickness of the tissue where the fibers are stretched and free is changed. Thin, so when the process terminal is heated and hardened, there will be a very high ratio of uneven thickness of the finished product; this phenomenon has been studied to show the operation of the "fibrous substrate" impregnated in the middle and rear ends. The source of the "mixed dipping" concentration injected into the "prepreg" has been found to be weaker, and the absorption capacity of the "fibrous substrate" is weakened and the frictional resistance of the relative operation becomes larger. The tensile deformation of the "impregnated fiber substrate" is further aggravated.
