At present, wood or plastic is often used as a board material for the children drawing board in the market, firstly, the wood is heavy, forest resources are easily damaged, and secondly, the plastic is not easy to degrade, so that ecological environment is not protected. And a qualified drawing board must have the basic functions of insect prevention, mildew prevention and sanitation and cleanness. Along with the improvement of adult health consciousness, the drawing board for children also has higher screening standard. Therefore, the method for manufacturing the environment-friendly novel child drawing board is necessary to solve the defects of the existing child drawing board and provide the environment-friendly novel child drawing board which can meet the needs of children.
Tremella (Tremella fuciformis) is also called tremella, etc., belonging to Tremellaceae (TREMELLACEAE) and Tremella (Tremella), and is a common fungus for both food and medicine. The tremella fruit body contains rich bioactive substances and has good effects in resisting aging, resisting tumor, reducing blood sugar, lowering blood pressure and the like. The tremella in China has rich resources, and the tremella yield is in the leading position in the world. At present, the bag material cultivation is a main cultivation method of tremella, and has the advantages of wide raw materials, low cost, short period, high yield, good marketing, high economic benefit and the like, and the yield of dry tremella per 100kg of cultivation material is 8-15 kg. Gu Tian county is the main production area of tremella, more than 2 hundred million bags of tremella are produced annually, 10 ten thousand t waste fungus chaff is produced annually, and a large amount of waste materials such as tremella pedicel heads, rotten mushrooms and the like are difficult to dispose. When only one edible fungus processing plant normally produces, 200-300 kg of waste materials such as tremella pedicel heads can be produced in 1 d. With the expansion of the tremella cultivation scale, tremella waste is more and more, the quantity is huge, the timely treatment of tremella waste is very necessary, otherwise, the incineration of the waste is easy to cause resource waste and serious environmental pollution.
