Problems solved by technology

During long-term use, it is found that the writing liquid will penetrate into the board, resulting in ink residue on the layout, which is difficult to erase with ordinary methods, affecting the teaching effect
Over time, it will also cause residual ink to corrode the board surface and reduce the service life of the board
At the same time, after long-term use of teaching whiteboards or matt boards, the surface will gradually be stained with stains, and the writing liquid cannot be spread evenly on the board, resulting in uneven ink marks and intermittent handwriting, which will affect the writing effect

The teaching whiteboard nursing agent is simple in formula, available in raw materials, and low in cost, and is a multi-purpose cleaning care agent.

Description

technical field [0001] The invention relates to daily-use chemicals, in particular to a care agent for teaching whiteboards. Background technique [0002] In order to eliminate the dust pollution caused by chalk writing on traditional blackboards, researchers have studied a variety of chalk substitute products, replacing traditional blackboards with whiteboards or matte boards, and replacing chalk with whiteboard markers. Due to the advantages of smooth writing, easy erasing, and dust-free, whiteboard pens are generally accepted by people and put into extensive use. During long-term use, it was found that the writing liquid would penetrate into the board, resulting in ink residue on the layout, which was difficult to erase with ordinary methods, affecting the teaching effect. Over time, it will also cause residual ink to corrode the board surface and reduce the service life of the board. At the same time, after long-term use of teaching whiteboards or matt boards, the surf...
