The invention relates to a rotation type automatic erasure blackboard based on a high temperature vanishing pen. The rotation type automatic erasure blackboard based on the high temperature vanishing pen comprises a control motor, a rotation device and a heating device, wherein the rotation device comprises an aluminum frame, an upper roller located at the top of the aluminum frame, a lower roller located at the bottom of the aluminum frame and an artificial leather arranged between the upper roller and the lower roller, wherein a liner plate is arranged on a position behind the artificial leather, 3mm away from the artificial leather, the upper roller and the lower roller are longitudinally symmetrically arranged, the heating device comprises two V-shaped frames which are horizontally symmetrically arranged, and a heating rod and a press roller which are arranged between the two V-shaped frames, the V-shaped frames are arranged above the lower roller, one end of the artificial leather is connected with the upper roller, and the other end of the artificial leather is connected with the lower roller after respectively bypasses the hearing rod and the press roller. The rotation type automatic erasure blackboard based on the high temperature vanishing pen is compact in structure and high in erasure efficiency, improves teaching environments of teachers and students, and difficultly reflects light, and furthermore the artificial leather used on the rotation type automatic erasure blackboard based on the high temperature vanishing pen has the advantages of resisting abrasion, and being fadeless, good in water repellency, recyclable and the like.

The hollow decorative PVC gusset is produced with PVC material and through the processes of mixing material, molding with the high temperature molten mixture to form soft hollow decorative gusset blank, and vacuum adsoption and cooling to set. It has the features of being fireproof, fadeless and antiaging, and it may be produced into various standard for different application.

The invention relates to an insulated facing integrated inorganic section and a preparation method thereof. The section consists of an insulated basal body and a facing layer which are made of various inorganic mineral materials, wherein the insulated basal body is prepared from inorganic slat composite slurry-like kernel materials and expanded perlite grain materials; and the facing layer is prepared form quartz sand, calcium carbonate, calcium oxide, cement, silicon oxide ultrafine micro powder and wood finer ultrafine micro powder. The section is formed by integrally pressing and compounding the insulated basal body and the facing layer, ensures that two layers of materials are organically combined together, can completely avoid the phenomena of the cracking and the shedding between the insulated basal body and the facing layer, can reliably improve the manufacturing precision and the standard grade, can greatly reduce the workload of the wall body decorated construction, improve the construction efficiency, reliably ensure the engineering quality, and can greatly shorten the engineering period and save the material cost and engineering cost under the same conditions.
