Abstract
An enamel projection blackboard includes a blackboard body and a frame coated on a periphery of the blackboard body; the blackboard body includes a metallic steel plate layer; the enamel projection blackboard is characterized in that a nickel layer, an lac varnish enamel varnish layer and an enamel surface layer are successively distributed on a top surface of a metallic steel plate; and the lac varnish enamel varnish layer and the nickel layer are successively distributed on a bottom surface of the metallic steel plate from top to bottom. The enamel projection blackboard has high wear resistance and high surface hardness achieving HV 9.5; and a blackboard surface will not be damaged due to general impacting, wearing and scratching and is non-fading.
Description
Technical field
The utility model relates to a kind of blackboard, particularly relates to a kind of Enamelled blackboard that has the blackboard function and the screen function of excellence concurrently.
Background technology
Blackboard had available chalk function such as writing words, figure from the teeth outwards in the past; In order to write, erase literal, figure etc. with chalk easily; When making blackboard the blackboard surface is suitably increased slightly, and use the material powder of dead color for the literal that uses chalk to write, image etc. watch easily.
But in recent years, normally utilize various projectors such as slide projector, OHP, preprepared data is projected on the screen, describe with the equilateral indication of indicating bar etc.
Yet, attending projection image if make at existing blackboard with projection, image quality is dim, and is not distinct, and therefore, existing blackboard can't be used as screen.
The utility model content
The purpose of the utility model is to solve the problem that above-mentioned prior art exists, and a kind of excellent blackboard that has concurrently is provided, and can be used as the enamel projection blackboard of projection screen simultaneously again.
The technical scheme that adopts:
The enamel projection blackboard of the utility model; Comprise the blackboard body and be coated on the peripheral frame of blackboard body; It is characterized in that described blackboard body comprises the metallic steel flaggy; Be distributed with nickel dam, lac varnish enamel paint layer and enamel top layer on the end face of said metal foil successively, the bottom surface of said metal foil is distributed with nickel dam and lac varnish enamel paint layer downwards successively.
The production principle of the utility model:
One, enamel projection blackboard metallic plate production principle: enamel projection blackboard metallic plate is on special antirust steel-sheet basis; Adopt the making prescription and advanced production technology of specialty; The unorganic glass material is coagulated on metal foil through fusion, fire a kind of composite that together forms with the steel plate strong bonded through 1000 ℃-1200 ℃.
Two, material and manufacture craft:
(1) enamel projection blackboard metallic plate plate face base material: enamel generally is meant the mild steel steel plate with steel (steel plate); Be the steel plate of phosphorus content the end of than! Yi Ban ≦ 0.08%), its chemical composition, interior microscopic institutional framework (structure), surface appearance and mechanical property play an important role to the quality of enamel.Surface of steel plate is done antirust processing.
(2) enamel projection blackboard metallic plate plate face enamel raw material mainly comprises three major types: raw mineral materials, industrial chemicals and pigment raw material.
Raw mineral materials is the main component of enamel, occupies the content of larger specific gravity.It mainly comprises: quartzy (main component is silica one SiO2), feldspar (silicate of alkali metal or alkaline-earth metal, potassic feldspar commonly used-K20A12036SiO2), clay (moisture aluminium silicon salt mineral are mainly the A12036Si02 and the crystallization water).
Industrial chemicals is the auxiliary part of enamel.It mainly comprises: borax (Na2B40710H20), sodium nitrate (NaN03), soda ash (Na2C03), lithium carbonate (Li2C03), calcium carbonate (CaC03), magnesia (MgO), zinc oxide (ZnO), titanium dioxide (Ti02), antimony oxide (Sb203), zirconium dioxide (Zr02), cobalt oxide (CoO) nickel oxide (NiO), manganese dioxide (Mn02), iron oxide (Fe203).
Pigment raw material is meant the material that is used for the decorative porcelain glaze color.Be divided into: 8 kinds of black, blueness, brown, grey, green, pink, white, yellow etc.What enamel projection blackboard metallic plate adopted is blackish green.
(3), manufacture craft: the making of enamel projection blackboard metallic plate plate face is according to certain ratio with three kinds of above-mentioned raw materials; High-temperature fusion through about 1200 ℃; And through the rapid borosilicate glass matter that is cooled to granular or sheet; Sintering is in the metal surface of doing anticorrosion, with the steel plate strong bonded together.Make enamel projection metallic plate that intrinsic mechanical strength of metal and processing characteristics arranged, the characteristic such as wear-resisting, heat-resisting, corrosion-resistant, nontoxic that has again that coating has.This plate face reaches ceramic hardness, draws no vestige with alloy cutter.
The utility model has the advantages that:
(1) mar proof: product has higher anti-wear performance, and general bump, wearing and tearing, scraping can not damage the plate face, and the surface is colour-fast, and case hardness can reach Vickers 9.5.
(2) heat-resisting, fire line: the enamel sintering process is adopted on the surface, and is absolutely not flammable.
(3) hardness test: with the metal sharp object plate face that rows dry, panel does not have to show money or valuables one carries unintentionally, do not have and scratches vestige.
(4) magnetic: the surface is suitable for all magnetic attachment, can in contact, not cause surperficial any damage.
(5) writing property: surface smoothing, to write very laborsavingly and smooth, its exclusive characteristic can be practiced thrift 50% chalk nearly.
(6) visuality: product has splendid definition and bigger contrast, the vision protection write.
(7) be prone to wiping property: the vestige that uses dried cloth or ordinary blackboard eraser just can very like a cork chalk be write is cleaned.
(8) ease for maintenance: adopt the surface dust degree of retaining behind the wet rubbing to be no more than 0.5, any special soda acid cleaning Ji all can't deface, and service life was in 30-50 years.
The characteristic of enamel projection metallic plate projectable:
Enamel projection metallic plate is a kind of special metallic plate of writing of development newly; Advanced material prescription makes has special performance: the plate face can be made projection screen and use; Can image directly be projected to Display projector clear picture on the plate face of enamel projection metallic plate, real colour with projector.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The enamel projection blackboard of the utility model comprises metal foil 1, is characterized in upwards being distributed with nickel dam 2, lac varnish enamel paint layer 3 and enamel top layer 4 successively at the end face of metal foil 1, is distributed with nickel dam 2 and lac varnish enamel paint layer 3 downwards successively in the bottom surface of metal foil 1.
