Embodiment 1

[0019] A method for making clothes hangers from sawdust, comprising the following steps:

[0020] (1) Sawdust treatment: Coarsely crush the sawdust after picking out impurities and pass through a 20-mesh sieve, then wash and filter with water and dry for the first time until the water content is 45%; put the sawdust after the first drying Soak in 0.5% dodecyl tertiary amine saline solution at a temperature of 70°C while stirring for 6 hours, rinse with deionized water until it becomes neutral, filter with suction, and dry for the second time until the water content is reached. 9%, crushed again and sieved 100 meshes to obtain the primary modified wood chips; put the primary modified wood chips into a closed pyrolysis furnace with a temperature of 250-280°C and pyrolyze them for 5 hours, then cool them down to normal temperature with isolated air to obtain the secondary modified wood chips. sex sawdust;

[0021] (2) Mixing of raw materials: in parts by weight, weigh 50 parts o...

Abstract

The invention belongs to the technical field of daily living articles and specially discloses a method for manufacturing a clothes hanger with wood chips as the raw material. The method for manufacturing the clothes hanger with the wood chips as the raw material comprises the following steps of (1) processing the wood chips, wherein the dried wood chips are processed through an amphoteric surfactant BS-12 aqueous solution, then primarily-modified wood chips are obtained, pyrolysis is conducted on the primarily-modified wood chips, and then re-modified wood chips are obtained; (2) mixing raw materials, wherein by weight, a certain parts of the primarily-modified wood chips, the re-modified wood chips and an adhesive are weighed and evenly mixed; (3) conducting compression molding; (4) spraying finishing paint. According to the method for manufacturing the clothes hanger with the wood chips as the raw material, the wood chips are used as the raw material, the wood chips are modified, then the wood chips, the adhesive and the like are mixed and placed in a mold to be pressed to form the clothes hanger, in this way, the application range of the wood chips is expanded, the additional value of wood chip machining is increased, and the manufactured clothes hanger has good mechanical performance.

Description

【Technical field】 [0001] The invention relates to the technical field of daily necessities, in particular to a method for making clothes hangers from sawdust. 【Background technique】 [0002] Wood is a biomaterial that is easy to process and has relatively high strength. As an industrial and domestic material, it can highlight the advantages of carbon sequestration, emission reduction, low-carbon energy saving, and thus has been widely used. The growth of existing timber plantations cannot meet the ever-increasing demand for timber. As the residue of wood processing, wood chips are also increasing with the continuous increase of wood usage. Existing wood chips are usually used as fuel, fertilizer and feed, with low utilization rate and few uses, and the added value of wood chip processing is low. 【Content of invention】 [0003] The object of the present invention is to provide a method for making clothes hangers from sawdust in order to solve the above problems. The inven...
