Description
Technical Field
The invention belongs to the technical field of wood treatment, and particularly relates to a recombined decorative material iron mold and a maintenance method thereof.
Background
In order to make the recombined decorative material present natural textures of natural precious material species, a mold is needed to be used for pressing in the production process, the mold material of the common recombined decorative material is wooden, and three reasons are mainly adopted: firstly, the price is low; secondly, the maintenance is convenient; and thirdly, the wood veneer is tough and not easy to crush and crack. However, in some special varieties, such as the products imitating the roots of natural cat-eye trees, the material of the die needs to be hard in order to achieve the effect of clear textures, so that the iron die is introduced into the invention. However, after the iron mold is used for a long time, and due to the fact that the iron mold is corroded by humid air, the glue penetrates through the iron mold and artificial loss, the local main body is uneven, the hemispherical protrusions are loosened, small deformation and damage occur, the iron mold is used for locally crushing and fracturing the single plates in the process of pressing the single plates, and the single plates cannot be used.
Disclosure of Invention
The invention aims to provide a maintenance method of a recombined decorative material iron mold, wherein the recombined decorative material iron mold is made of an iron material, the mold comprises a rectangular mold main body, the left side and the right side of the mold main body are respectively provided with two fixing pieces, the two fixing pieces are respectively close to the front side and the rear side of the mold main body, a plurality of hemispherical bulges are distributed on the surface of the mold main body, the heights of the bulges are consistent, so that the bulges are uniformly contacted with a single plate, and the maintenance method comprises the following steps:
step 1) firstly, polishing the whole mould surface once by using a cleaning ball, and removing rust and glue blocks adhered to the mould main body and the periphery of a hemisphere;
step 2) inspecting the die, inspecting the heights of all hemispheres by using a horizontal ruler, and polishing the raised points by using an angle grinder and a polishing sheet to make the heights of the raised points consistent; then, coating the whole mold surface with a mixture of urea-formaldehyde resin with the viscosity of 200-400 MPa & s and polyvinyl chloride, wherein the coating thickness is 0.5-1 mm, standing for about 10 minutes, then, spraying the mold surface with a spray gun by using rosin water, observing the mold surface after the coated object is completely dried, and observing whether the main body part is in a horizontal state or not and whether concave places exist or not, if so, repeating the above two-step coating process, and maintaining the problem point that the main body is concave less than 3 mm in the above mode; if the local concave depth of the main body is more than 3 mm, before painting, flour and polyvinyl acetate emulsion are uniformly mixed according to the proportion of 1.5:1, then the concave part is filled and leveled, and then painting process is carried out.
Preferably, the weight ratio of the urea-formaldehyde resin to the polyvinyl chloride is 2: 1.
the maintenance method provided by the invention is used for maintaining the iron mould which is used for a long time and has defects, so that the frequent replacement of the iron mould is avoided, the maintained mould has no difference with a new mould in the operation process, the condition of fracturing a veneer is avoided, the texture is natural and clear, and the method is economical and environment-friendly.
Drawings
Fig. 1 is a schematic structural view of a recombined decorative material iron mold provided by the invention.
Detailed Description
Example 1
The utility model provides a reorganization decorative material iron mould, this mould includes rectangle mould main part 1, the mould main part left and right sides is equipped with two stationary blades 2 respectively, two stationary blades 3 are close to the front side and the rear side of mould body respectively, mould main part surface distribution has a plurality of hemisphere protruding, protruding highly uniform, like this, when this mould pressfitting veneer, the most high point of all hemisphere protrusions in the mould contacts with the veneer at first, and the contact surface is big, and is even moreover, is difficult to cause the fracturing of veneer.
The length of the main body of the rectangular die is 2.7m, the width is 0.72 m, the thickness is 5cm, the number of the protrusions is about 3000 and 5000, the protrusions are uniformly distributed on the surface of the main body of the die, the diameter of the protrusions is 5-9 mm, and the height of the protrusions is 2-3 mm.
The die comprises a square fixing plate and a die seat, wherein the length of the fixing plate is 16 cm, the width of the fixing plate is 13 cm, and a fixing hole with the diameter of 5cm is formed in the middle of the square fixing plate, so that the fixing plate plays a role in fixing and is used for fixing the die on a cold press.
The recombined decorative material iron mold provided by the embodiment is hard, and the obtained veneer has natural and clear texture; is especially suitable for the products imitating the roots of natural cat eye trees.
In addition, the highest points of the hemispherical bulges are on the same horizontal plane, so that when the mold is used for pressing the single plate, the highest points of all the hemispherical bulges in the mold are firstly contacted with the single plate, the contact surface is large and uniform, and the single plate is not easy to fracture.
Example 2
The iron mould that embodiment 1 provided, long-time use, iron mould has appeared local main part unevenness because of the corruption of humid air, the infiltration of glue and artificial loss, and the hemisphere is protruding not hard up, has taken place little deformation and damage, causes the mould at pressfitting veneer in-process, causes the local crushing of veneer, fracturing, unable use. Therefore, the present embodiment provides a method for repairing the iron mold, which includes the following steps:
step 1) firstly, polishing the whole mould surface once by using a cleaning ball, and removing rust and glue blocks adhered to the mould main body and the periphery of a hemisphere;
step 2) inspecting the die, inspecting the heights of all hemispheres by using a horizontal ruler, and polishing the raised points by using an angle grinder and a polishing sheet to make the heights of the raised points consistent; then, coating the whole mold surface with a mixture of urea-formaldehyde resin with the viscosity of 200-400 MPa & s and polyvinyl chloride, wherein the coating thickness is 0.5-1 mm, standing for about 10 minutes, then, spraying the mold surface with a spray gun by using rosin water, observing the mold surface after the coated object is completely dried, and observing whether the main body part is in a horizontal state or not and whether concave places exist or not, if so, repeating the above two-step coating process, and maintaining the problem point that the main body is concave less than 3 mm in the above mode; if the local concave depth of the main body is more than 3 mm, before painting, flour and polyvinyl acetate emulsion are uniformly mixed according to the proportion of 1.5:1, then the concave part is filled and leveled, and then painting process is carried out. Wherein the weight ratio of the urea-formaldehyde resin to the polyvinyl chloride is 2: 1.
the iron mould main body maintained by the process is in a horizontal state, the hemispherical protrusions are basically on the same horizontal plane, the maintained mould is not different from a new mould in the operation process, the condition of fracturing a veneer is avoided, and the texture is natural and clear.
