Abstract

The invention provides a reusable study notebook. The reusable study notebook comprises erasable paper, wherein the erasable paper comprises an oil film paper layer and a writing paper layer covered with the oil film paper layer. Writing on the reusable study notebook can be erased with a common medium, and the notebook can be recycled for a user. The reusable study notebook further can be provided with a first permeable film layer, a spunlace non-woven fabric layer and a second permeable film layer arranged sequentially from top to bottom below the writing paper layer, wherein the spunlace non-woven fabric layer is soaked in a writing erasing liquid, each of the first permeable film layer and the second permeable film layer is provided with a plurality of vent holes in the position corresponding to each word cell of the writing paper layer, a hardboard with predetermined thickness is arranged below bound pieces of erasable paper and is provided with a groove in the position corresponding to each word cell of the writing paper layer, and an ultrasonic oscillator is arranged in each groove. With introduction of the ultrasonic oscillators and other components, the writing of the reusable study notebook is more convenient to erase, and the efficiency is higher.

Description

technical field [0001] The invention relates to the field of stationery, in particular to a multi-purpose learning book. Background technique [0002] In modern society, people cannot do without the use of paper in their daily lives, but the waste water, waste gas, waste residue, toxic substances and noise produced in the production of the paper industry will cause serious pollution to the environment, especially water pollution. It is used in the paper industry and has a large displacement. Generally, it uses more than 300 tons of water per ton of pulp and paper. Wastewater has high content of organic matter, high biochemical oxygen demand (BOD), high suspended solids (SS), and contains toxic substances, which are colored and smelly, endangering the normal growth of aquatic organisms, affecting industrial, agricultural, animal husbandry, residential water use and environmental landscape. Accumulated over the years, the suspended solids will silt up the river bed port and p...
