Abstract
The invention relates to a method for preparing carbonized bamboo chopsticks by utilizing carbonized bamboo chips with uniform shallowness, which is characterized in that the method comprises the process steps: 1. the pretreatment of a bamboo material, in which the bamboo material is transversely sawn at intervals along the length direction of the bamboo material, and each section of sawn bamboo material is chopped into four pieces; 2. bamboo material carbonization with uniform shallowness, in which the large bamboo materials are placed into a carbonization furnace, water vapor is introduced as shielding gas, the carbonization is performed for 2 to 3 hours at a temperature increase rate of between 5 and 10 DEG C/h, and finally the carbonization temperature reaches between 160 to 180 DEG C, 180 to 200 DEG C, 200 to 220 DEG C, and 220 to 40 DEG C respectively; and 3. the preparation of the carbonized bamboo chopsticks, in which joints of the obtained carbonized bamboo chips are subjected to grinding processing to be prepared into flat boards, and then a chopstick forming machine is utilized for processing to be formed. The method has the advantages that the carbonized bamboo chopsticks are not added with any chemical agent during the production, has no pollution and simple treatment process, and has the advantages of good durability, dimensional stability, moisture protection, mold prevention, moth prevention, sterilization, powerful self-purification function and so on.
Description
Technical field
What the present invention relates to is to propose a kind of method of utilizing the even charing bamboo chip of shallow degree to prepare charing bamboo chopsticks.Belong to bamboo chopsticks preparing technical field.
Background technology
In daily life, people's bamboo wood commonly used is made chopsticks, though cost is low, because sugar and moisture in the bamboo wood are higher, makes bamboo chopstick be subjected to mould alteration matter easily, also usually by some insect moth foods.Bamboo chopsticks are damaged by worms after the food, uneven speckle moth trace gently then occurs, though can use not attractive in appearance and useful life not long, heavy then form channel, bamboo eaten hollow fracture, can not continue use.Mothproof method also has a lot, as high-temperature process, coating processing, chemicals treatment etc., though these processing methods can reach mothproof purpose, but these methods respectively have the drawback part, directly will make good bamboo chopsticks high-temperature process, and dehydration can take place glucosyl group in the contained cellulose macromolecule of bamboo chopsticks, its water absorbing functional groups hemicellulose is recombinated, cause bamboo chopsticks distortion, influence attractive in appearancely that coating and chemicals treatment can pollute and unfavorable to health environment.
Summary of the invention
Purpose of the present invention is intended to overcome the above-mentioned defective of existing in prior technology, proposes a kind of method of utilizing the even charing bamboo chip of shallow degree to prepare charing bamboo chopsticks.
Technical solution of the present invention: this method comprises following processing step:
One, bamboo wood preliminary treatment: the length direction of bamboo wood press fixed certain intervals laterally sawed-off, sawed-off each section bamboo wood is split into four.
Two, the even charing of the shallow degree of bamboo wood: large stretch of bamboo wood is placed retort; feed a certain amount of water vapour as protection gas; programming rate with 5～10 ℃/hour; charing 2～3 hours, final carbonization temperature reaches 160～180 ℃, 180～200 ℃, 200～220 ℃, 220～240 ℃ respectively.
Three, charing bamboo chopsticks preparation: the charing bamboo chip joint portion that obtains is carried out grinding, make flat boards, utilize the machine-shaping of chopsticks make-up machine again, the hand engraving surface detail.
Preferred programming rate is 5 ℃/hour, carbonization time 2 hours, and final carbonization temperature is 180～200 ℃, 200～220 ℃ and 220～240 ℃.
Charing bamboo chopsticks by measure its MOR, elastic modelling quantity, impact flexibility, tangential shrinkage, radially drying shrinkage, tangential wet rising property and radially the variation size of physico-mechanical propertieses such as wet rising property determine optimum process condition, i.e. influence factors such as programming rate, carbonization time and carbonization temperature.
Advantage of the present invention: the present invention is with bamboo wood elder generation charing reshaping, avoided the first moulding distortion situation of charing again, and decomposition sex change such as remaining sugar, fat, starch, cellulose in the bamboo wood in producing, be converted into inorganic substances from organic substance, thereby make and do not contain any nutriment in the bamboo wood, fundamentally eliminate the living space of entomogenous fungi, make it have antiseptic insect-repelling function preferably; Recombinated owing to its water absorbing functional groups hemicellulose simultaneously, make product have good physical property, it is real Green Product, do not add any chemical agent, do not contain any harmful substance, can to human body, animal and environment any negative effect not arranged in the waste disposal process after producing, use and using.
The specific embodiment
Embodiment 1; the direction of growth of bamboo wood press fixed certain intervals laterally sawed-off; each section bamboo wood is split into four; again large stretch of bamboo wood is placed the even charing of the shallow degree of retort; in retort, feed a certain amount of water vapour as protection gas; with 5 ℃/hour programming rate, charing 2 hours, final carbonization temperature reaches 220～240 ℃.The charing bamboo chip joint portion that obtains is carried out grinding to polish.Utilize chopsticks make-up machine (having now) machine-shaping, available hand engraving surface detail.
The elastic modelling quantity of charing bamboo chopsticks is 5305MPa, and MOR is 37.75MPa, and the tangential shrinkage rate is 1.656%, and radially contract with dry rate is 1.238%; Tangential wet rising property rate of descent be 55.24% and the rising property rate of descent that radially wets be 50.76%.
Embodiment 2; the direction of growth at bamboo wood is laterally sawed-off at regular intervals; each section bamboo wood is split into four sheets; again large stretch of bamboo wood is placed the even charing of the shallow degree of retort; in retort, feed a certain amount of water vapour as protection gas; with 5 ℃/hour programming rate, 2 hours h of charing, final carbonization temperature reaches 200～220 ℃ respectively.The charing bamboo chip joint portion that obtains is carried out grinding to polish.Utilize the machine-shaping of chopsticks make-up machine, the hand engraving surface detail.
The elastic modelling quantity of charing bamboo chopsticks is 5363MPa, and MOR is 38.28MPa, and the tangential shrinkage rate is 1.996%, and radially contract with dry rate is 1.4299%; Tangential wet rising property rate of descent be 48.30% and the rising property rate of descent that radially wets be 47.95%.
Embodiment 3; the direction of growth at bamboo wood is laterally sawed-off at regular intervals; each section bamboo wood is split into four sheets; large stretch of bamboo wood is placed the even charing of the shallow degree of retort; in retort, feed a certain amount of water vapour as protection gas; with 5 ℃/hour programming rate, charing 2 hours, final carbonization temperature reaches 180～200 ℃ or 160～180 ℃ respectively.The charing bamboo chip joint portion that obtains is carried out grinding to polish.Utilize the machine-shaping of chopsticks make-up machine, the hand engraving surface detail.
