Description

Glass fiber reinforced plastic magnetic black and white board

Technical Field

The utility model relates to an education and culture article, in particular to a glass fiber reinforced plastic magnetic black and white board.

Background

Before the invention of characters, people find that charcoal can be used for drawing pictures, ancient murals can be found in ancient rock caverns in Europe, and the rock walls on which the murals are drawn can be called as blackboards in a traditional sense.

Ancient Chinese teaching is a multi-purpose article called a sand table, which is repeatedly written on sandy soil by using hardwood, but the sandy soil cannot be considered as a blackboard because the sandy soil is soft; in the middle century, people found that lime and water are mixed to form blocks, and writing is carried out on the surfaces of dark hard objects by a method similar to a charcoal pen, and people coated the surfaces of wood boards with black paint to protect the wood boards from being corroded in the 19 th century, although the main function of the blackboard is not teaching at that time, the black board is not popular in schools all over the world until the middle of the 19 th century; over two hundred years, blackboards have been coated with black paint on the surfaces of hard objects such as wood boards and cement from the earliest to the surface of water-milled glass, color-coated steel plates, composite plates and the like in the nineties; the one-step development of the world education cause is witnessed, the knowledge is spread for human, the education is popularized, and the pommel horse is set. The types of the existing blackboards also become complex and diversified, and the blackboards, the green boards and the white boards are divided into a plane board and an arc panel from the surface shape, a support movable board, a push-pull board, a lifting board and a magnetic blackboard from the structural composition, and a teaching blackboard, an office whiteboard, a billboard, a display board and the like from the purpose; the teaching blackboard comprises an electronic blackboard, a multifunctional combined board, a combined push-pull blackboard, an interactive electronic whiteboard, a projection board with a screen and the like.

At present, primary and secondary schools adopt an obligation education system, in order to improve the quality and learning ability of students, some collective teaching activities are often required to be carried out, the activities are generally temporary, the field is limited, in order to better enable the lecturer to express the teaching content clearly, the blackboard is required to be used for writing, two boards, one blackboard and one white board are always prepared in the past, thus the workload of arranging the field is increased, the two blackboards also need to increase the activity range of the lecturer, and the problems of lecture dragging the hall and the like are caused sometimes; in addition, the existing blackboard is not wear-resistant, and the blackboard is easily scratched after long-time writing on the surface of the blackboard, so that the problem is not well solved all the time.
