黑板并不是特指黑色的板面，傳統(tǒng)黑板是一個(gè)可以用粉筆反復(fù)書寫的平面，板面堅(jiān)硬，多用于教學(xué)。黑板按顏色分類多為黑色，墨綠色，白色或米黃色。制作黑板的材料有木材、水泥、水磨玻璃、彩涂鋼板、復(fù)合材料板、金屬鋼等，挑選黑板除了選擇材質(zhì)外，還應(yīng)根據(jù)需要選擇不同的種類和功能。
Blackboard does not specifically refer to the black board surface, the traditional blackboard is a plane that can be written repeatedly with chalk, the board surface is hard, mostly used for teaching.Blackboards are mostly classified by color as black, dark green, white or beige.The materials for making the blackboard are wood, cement, frosted glass, color-coated steel plate, composite material plate, metal steel, etc. In addition to choosing the blackboard material, we also should choose different types and functions according to the needs.
黑板用彩涂鋼板板面采用涂以耐磨涂層的優(yōu)質(zhì)合金鋼板,板面厚度多為0.3mm-0.4mm，彩涂鋼板材質(zhì)的黑板耐磨、不脫落、不褪色、經(jīng)久耐用、書寫手感好、字跡清晰、易寫、易擦試、粉塵少。
Blackboard color coated steel plate with high quality alloy steel plate coated with wear resistance coating, plate surface thickness of 0.3mm-0.4mm, color coated steel plate material board wear resistance, do not fall off, do not fade, durable, good writing feel, clear handwriting, easy to write, easy to test, less dust.
還有一種常見的黑板材質(zhì)是金屬鋼制黑板。一般采用磁性彩涂鋼板制作，板面厚度多在0.2mm—0.4mm之間，此種材料有耐磨，不脫落，不褪色，經(jīng)久耐用等特點(diǎn)，并且書寫手感好，字跡清晰，易寫易擦。內(nèi)芯材料為七層消音防潮瓦楞紙，背板為防銹熱鍍鋅板，邊框?yàn)橄銥I色高強(qiáng)度電泳鋁合金，美觀大方。
There is also a common blackboard material is metal steel blackboard.Generally, magnetic color coated steel plate is made, and the plate thickness is mostly between 0.2mm—0.4mm. This material has wear resistance, no falling off, no fade, durability, and good writing feel, clear handwriting, easy to write and easy to wipe.The inner core material is seven layers of silenced and damp-proof corrugated paper, the back plate is rust-proof hot galvanized plate, and the frame is Xiangbin color high-strength electrophoretic aluminum alloy, beautiful and generous.
為什么現(xiàn)在的黑板多是墨綠色？
因?yàn)?/span>相比傳統(tǒng)的純黑色黑板，墨綠色的黑板能夠使被色粉筆與黑板的反差變小，具有更加護(hù)眼、降低視覺疲勞的作用，目前部分地區(qū)的教育局出臺(tái)了使用綠色黑板的規(guī)定，用來(lái)保護(hù)兒童的視力。
Why is the blackboard mostly dark green?
Because compared with the traditional pure black blackboard, the dark green blackboard can make the contrast between the colored chalk and the blackboard smaller, has more eye protection, reduce visual fatigue, the education bureaus of some areas have issued the use of green blackboard regulations, to protect children's vision.
總的來(lái)說(shuō)，雖然不同的黑板的材質(zhì)和功能不同，但并不影響使用需求，所以我們購(gòu)買時(shí)主要考慮的是使用感受，例如書寫手感、耐久度、觀看者的感受等等。從性價(jià)比和使用角度而言，彩涂鋼板材質(zhì)的綠色黑板，這類產(chǎn)品也是目前最為主流的產(chǎn)品分類。佛山市萬(wàn)慶物資有限公司也常備墨綠色0.3-0.4mm厚的黑板用彩涂鋼板，經(jīng)銷國(guó)內(nèi)外鋼廠，總有一款適合您！歡迎來(lái)電或微信咨詢~
In general, although the materials and functions of different blackboards are different, they do not affect the use needs, so we mainly consider the feeling of use, such as writing feel, durability, the viewer's feelings and so on.From the perspective of cost performance and use, it is more recommended to color coated steel plate material of green blackboard, this kind of products are also the most mainstream product classification.Foshan Wanqing Materials Co., Ltd. also always has a dark green 0.3-0.4mm thick blackboard with color coated steel plate, the distribution of domestic and foreign steel mills, there is always a suitable for you!Welcome to call or WeChat consultation ~
