Abstract
The invention provides a processing method for a graphite HB carbon core. The method is characterized by comprising the following steps: (1) crushing crystalline flake graphite into graphite powder with a fineness of 700 meshes and carbon content of 90 to 95; (2) putting 50 to 70 kg of water-soluble wax, 30 to 50 kg of clay, 10 to 15 kg of thin maltose and 10 to 18 kg of high pigment carbon black into 110 kg of a main material; (3) uniformly mixing all the materials mentioned in the step (2) with stirring and putting an obtained mixture into a kneader for kneading for 3 to 4 h at a temperature of 45 to 55 DEG C; (4) subjecting a kneaded material to cold rolling so as to allow material thickness to be in a range of 0.3 to 0.5 mm; (5) putting a rolled material into a storage tank and storing the material for 72 h for subsequent usage; and (6) putting the material obtained in the step (5) into a core pressing machine to extrude out a graphite smooth pencil core with a certain scale. The processing method has the following beneficial effects: the method is simplified and improved on the basis of conventional process, machinery equipment is not improved, so the method can be directly applied in conventional production technology and is simple and easily practicable.
Description
Technical field
The present invention relates to pencil manufacture field, relate in particular to a kind of graphite HB carbon element core working method.
Background technology
On existing pictorial skill, have thick writing brush to be stained with ink and paint on paper, this pictorial skill " scribbling sketch ".Pass on from one to another and the Tang Dynasty, continue into the present always.Liquid owing to adopting, carry inconvenience, and waste is a lot, can not meet the service requirements of tyro and field environment.
Summary of the invention
The object of the invention is, for existing defect, to provide for the deficiencies in the prior art.The invention provides the water-soluble lead for retractable pencil working method of a kind of graphite, its objective is and utilize modern pencil processing technology, taking graphite as raw material, through batching processing, produce a kind of drawing product that can replace ink, realize the transformation of graphite high added value, for the deep processing of pencil creates direction.
The present invention is achieved by the following technical solutions, developed a kind of graphite HB carbon element core working method, it is characterized in that comprising the following steps:
(1) crystalline flake graphite is ground into Graphite Powder 99, order number is 700 orders, and carbon content is 90-95;
(2) in major ingredient 110kg, place water-soluble wax 50-70kg, clay 30-50kg, malt sugar 10-15kg, high-carbon black pigment 10-18kg;
(3) material of step (2) is stirred, be placed on and in kneader, mediate 3-4 hour; Temperature 45-55 degree Celsius;
(4) by the material cold reduction after mediating, make its material thickness at 03-0.5 millimeter;
(5) material rolling is placed in hold-up vessel and stores 72 hours with for subsequent use;
(6) material of step (5) is put into the core machine of pressing, extruded the smooth lead for retractable pencil of graphite of certain scale.
In described step (2), malt sugar is corn malt sugar.
Described step (4) is wanted cold reduction, and material thickness is 03-1.6 millimeter, and moisture content is 18%.
The positively effect of invention is: the present invention is taking Graphite Powder 99 as basis, selects reasonably formula, by the production technique of science, adopts process for processing lead for retractable pencil process exploitation to go out high-tech product.And because technique of the present invention is to simplify to improve on existing technological process basis, machinery equipment etc. is not improved, therefore can directly apply in existing production technique, simple.
Specific embodiment:
Example 1:
First prepare raw material: with pulverizing later Graphite Powder 99, fineness is 700 orders, and carbon content 92, gets 110kg.Batching: water-soluble wax is 50, clay 40kg, malt sugar 10kg, high-carbon black pigment 10kg.All material is stirred, mediate 3 hours, temperature keeps 36 degrees Celsius, and then cold reduction is 0.4 millimeter, and the material that moisture content is 18% is placed in hold-up vessel 72 hours, finally puts into the water-soluble lead for retractable pencil of HB graphite of pressing core machine to extrude Φ 2.0.Produce graphite HB carbon element pencil by the technique of normal production Wood-bar pencil.
Example 2:
First prepare raw material: with pulverizing later Graphite Powder 99, fineness is 700 orders, and carbon content 94, gets 110kg.Batching: water-soluble wax is 60, clay 30kg, malt sugar 10kg, high-carbon black pigment 10kg.All material is stirred, mediate 3 hours, temperature keeps 30 degrees Celsius, and then cold reduction is 0.35 millimeter, and the material that moisture content is 18% is placed in hold-up vessel 72 hours, finally puts into the water-soluble lead for retractable pencil of 6B graphite of pressing core machine to extrude Φ 3.0.Produce graphite HB carbon element pencil by the technique of normal production Wood-bar pencil.
In actual applications, those skilled in the art is other parameter of choose reasonable in technical scheme of the present invention completely again, produces HB; 2B, 3B, 4B; the product of the models such as 6B, but the technical scheme substance of protecting with the present invention is identical, still falls within the scope of protection of the present invention.
Claims (3)
