Description
Technical Field
The invention belongs to the field of furniture plates, and particularly relates to a high-temperature-resistant scratch-resistant composite plate for laboratory furniture.
Background
Furniture is functionally divided into civilian furniture and special industry furniture, such as laboratory furniture. As is well known, laboratories can be divided into a large number of uses, such as biological laboratories, chemical laboratories, physical laboratories, etc. Chemical laboratories use large amounts of acids, alkaline reagents, solutions, and a wide variety of highly corrosive chemicals; physical laboratories often produce strong vibrations or impacts when performing physical experiments. The safety of the laboratory environment is related to the personal safety of laboratory workers and the safety of laboratory equipment, so that the matching of furniture meeting requirements for laboratories with various functions is a work with very technical content.
At present, in the aspect of material selection, most of traditional laboratory furniture production and manufacture adopts solid physicochemical plates, Qianshi plates, epoxy resin plates, ceramic plates and other materials as table boards. However, they all have a common disadvantage in that the surface is very easily scratched and the repair is very difficult. Due to the scratch problem, the laboratory furniture often has the problems of table top warping deformation, foaming, bulging and the like.
The cabinet body of the laboratory furniture is usually made of materials such as melamine boards, galvanized steel boards, PP boards and the like. The melamine board is a melamine impregnated bond paper facing artificial board, and is a common furniture cabinet material in laboratory furniture manufacture. The material is often deficient in the following aspects in specific application and manufacturing process:
1. because the melamine veneer of the melamine board is very thin and brittle, when an operator cuts a material by using a cutting tool such as an electronic saw in production, the edge of the cut part is often broken and basically difficult to repair.
2. In the installation, because the substrate (shaving board, well density fiberboard or hard fiberboard) own constitution structure of preparation melamine board is comparatively loose, and the nail-holding power is not good when the furniture is connected, leads to furniture equipment back structure insecure, influences life, and the most common performance is: the drawer slide rail falls off and the door is blocked from opening.
3. In the using process, the melamine-modified water-based plate is very easy to be scratched by physical scraping, and the scratches left by the scraping cause moisture in the environment to penetrate through the melamine film and enter deep layers of the material, so that the plate body is cracked, and the block is mildewed and cannot be repaired.
4. The base materials for manufacturing the melamine board are all plant fibers which are easy to absorb moisture, and if the surface of the cabinet body is damaged or scratched, the base materials are easy to expand, and finally the cabinet body deforms or warps, and is seriously and directly disintegrated due to dampness.
Galvanized steel sheets are common and used materials in the production and manufacture of laboratory furniture cabinets, and are commonly used because the materials have high cost performance compared with melamine boards. However, the galvanized steel sheet causes the material to expand with heat and contract with cold due to the physical property of the metal and the sudden change of the natural air temperature and the laboratory environment temperature, so that the plastic powder attached to the surface of the material is forced to participate in the expansion with heat and contraction with cold, the physical property of the galvanized steel sheet is different, the specified expansion with heat and contraction with cold amplitude are different, and finally the plastic powder attached to the surface of the material falls off due to the irreconcilable contradiction. After the molding powder falls off, the exposed metal layer is exposed in the air, and finally rust spots are formed on the metal part which is not protected by the molding powder because the metal part cannot resist the corrosion of substances such as moisture, acid and alkali and the like.
The PP plate, as for the material itself, is a plastic, and has the following fatal defects:
the PP sheet material has poor cold resistance, low-temperature impact strength and easy cracking due to improper operation in a low-temperature environment.
2. PP material is very easy to burn, and various reagent chemical compositions in a laboratory are very complicated, and easy burning is a great potential safety hazard.
And 3, the toughness of the PP material is poor, so that the product cannot store articles with heavier quality, otherwise, a partition plate layer in the cabinet body collapses, and potential safety hazards exist.
The problems directly cause the service life of the furniture in the laboratory to be reduced, and directly or indirectly influence the overall environmental safety of the laboratory and the personal safety of operators in the laboratory.
