Embodiment Construction

[0020] A novel method for making paper-making multifunctional organic environmental-friendly thin film, the technological process of which is as follows:

[0021] a. Classify the raw materials of discarded tobacco leaves, tobacco stems, tobacco stems, and tobacco leaves into one category, shredded tobacco powder, and shredded tobacco leaves into one category, and dry to a moisture content of 12%±1% for later use.

[0022] b. Classify and weigh the raw materials according to the proportion, and send the raw materials into the air separator with feeding equipment to remove dust or foreign matter.

[0023] c. Send the stalk leaf raw material into a grinder for crushing and mix it with the minced leaf raw material quantitatively in a mixing tank with a stirring device.

[0024] d. Add water 3-5 times the weight of the raw materials into the mixing tank described in c, cook for 20-50 minutes while stirring, and pump into the beater to beat into a length of 10-20 mm.

[0025] e. Se...

Abstract

The invention discloses a method for manufacturing a paper making-process multifunction organic environmental-protection flaky mulching film. In the method, the waste stems, peduncles, pulverized powders, leaves and the like of plants or crops are used as raw materials, and a machining process can be effectively controlled according to the mechanical strength, the light transmittance, the ventilation, the heat preservation, the water retention or other particular effects (such as adding a sterilization disinfectant, an extra-nutrition element, a controlled release fertilizer and the like) demanded by the mulching film. The flaky mulching film manufactured by the method for manufacturing the paper making-process multifunction organic environmental-protection flaky mulching film has the advantage of economic and environmental protection characteristics, and has the characteristics of rich sources of the raw materials, low cost, biodegradability, soil improvement, time saving, labor saving, high controllability and the like.

Description

technical field [0001] The technology relates to a novel method for making a paper-making multifunctional organic environmental-friendly thin mulch film. Background technique [0002] Film mulching has brought changes in agricultural production methods and a leap in agricultural productivity due to its functions of increasing temperature, water retention, adjusting fertilizer, and suppressing weeds. It has been widely used in the production of food crops, economic crops, nurseries, flowers, vegetables, etc. middle. Since China introduced it in 1978, the area covered by plastic film has gradually expanded. As of 2005, it has reached 959,000 tons, and the application area has reached 13.53 million hm2. It is the country with the largest cultivation area covered by plastic film in the world. However, since the current mulch materials in China are polyethylene (PE) and polyvinyl chloride (PVC), which have a large molecular weight and are difficult to degrade under natural condi...
