Abstract
The invention relates to the fields of production and processing of pencils and particularly relates to a pencil core produced from straws. The pencil core is characterized by comprising the following components in parts by weight: 70-80 parts of straws, 30-40 parts of graphite and 15-25 parts of an adhesive. According to the pencil core, the content of carbon in ash produced after the straws are heated in an oxygen insulation manner is 40%, other contents such as silicon, potassium chloride and calcium can be utilized as the components of clay, and therefore, the ash can be integrally utilized; energy sources are saved, the cost is lowered, the straw resource is reasonably utilized, the produced pencil core can be utilized for smoothly writing, and dreg dropping is avoided.
Description
Technical field:
The present invention relates to the process for processing field of pencil, more specifically to the pencil-lead that a kind of stalk manufactures.
Background technology:
Stalk is the general name of ripe farm crop cauline leaf (fringe) part.Be often referred to wheat, paddy rice, corn, potato class, rape, cotton, sugarcane and other farm crop (the being generally coarse food grain) remainder after results seed.The photosynthetic product of farm crop has and is over halfly present in stalk, and stalk is rich in carbon, nitrogen, phosphorus, potassium, calcium, magnesium and organic matter etc., is that one has multiduty reproducible Biological resources.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the pencil-lead that existing technological deficiency provides a kind of stalk to manufacture.
Technical problem to be solved by this invention adopts following technical scheme to realize:
With the pencil-lead that stalk manufactures, it is characterized in that: it comprises stalk, graphite and tackiness agent, component is by weight: stalk 70-80 part, graphite 30-40 part, tackiness agent 15-25 part.
A making method for the pencil-lead that stalk manufactures, is characterized in that comprising the following steps:
(1) stalk is carried out pre-treatment, heat under sealing oxygen barrier environment, obtain ash content, Heating temperature is 500 DEG C, and the time is 3 hours;
(2) graphite is ground to form fine powder, add solvent after weighing with ash content, tackiness agent and mix under normal temperature condition;
(3) after mixing through mediating, roll-in rear panel is broken, play excellent extrusion molding;
(4) after pressing core, cutting core, carry out rotary drying again after extrusion molding, after drying, fill crucible, enter in roasting furnace to enter after roast and burn core stove burning core;
(5) clean through oil immersion, after drying, make pencil-lead.
Further, described solvent is the alcohol of concentration 70%.
Further, the oil used in described oil immersion process comprises the component of following weight part: the sesame oil of the ethanol of 60-70 part, the paraffin of 20-30 part, 30-40 part.
In the ash content produced after stalk oxygen barrier heating of the present invention, the content of carbon occupies 40%, other contain some can utilize as the composition of clay as silicon, Repone K, calcium composition, such ash content just can entirety utilize, present invention saves the energy, reduce cost, reasonably make use of stalk resource, the pencil-lead fluent writing produced, without falling slag.
