Abstract
A processing method of graphite resin 4B pencil lead is characterized by comprising the following steps: (1) crushing flake graphite into graphite powder with a mesh size of 800 mesh and the carbon content of 96-98; (2) placing 60-80kg of water soluble wax, 35-50kg of clay, 15-20kg of syrup and 5-10kg of high pigment carbon black into 130kg of a main ingredient; (3) mixing evenly the material of the steps (2), placing in a kneading machine for kneading for 3 to 4 hours; (4) cold rolling the kneaded material; (5) placing the rolled material in a storage tank for storage for 72 hours for standby use; (6) putting the material of the step (5) into a core pressing machine to press a graphite water soluble pencil lead with certain scale. The positive effects of the processing method are that: according to the processing method, the graphite powder is used as a basis, a reasonable formula is chosen, and by a scientific production process, a high-tech product is developed by a pencil lead production processing technology; and the processing method is simplified and improved on the basis of a technology process in the prior art without improvement of machinery equipment, so that the processing method can be directly applied to the technology process in the prior art, and is simple and easy.
Description
Technical field
The present invention relates to pencil manufacture field, relate in particular to a kind of graphite resin 4B lead for retractable pencil 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 a kind of graphite resin 4B lead for retractable pencil working method, 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 resin 4B lead for retractable pencil working method, it is characterized in that comprising the following steps:
(1) crystalline flake graphite is ground into Graphite Powder 99, order number is 800 orders, and carbon content is 96-98;
(2) in major ingredient 130kg, place water-soluble wax 60-80kg, clay 35-50kg, malt sugar 15-20kg, high-carbon black pigment 5-10kg;
(3) material of step (2) is stirred, be placed on and in kneader, mediate 3-4 hour;
(4) by the material cold reduction after mediating;
(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 water-soluble lead for retractable pencil of graphite of certain scale.
In described step (2), malt sugar is corn malt sugar.
The temperature of described step (3) kneader is 30 degrees Celsius.
Described step (4) is wanted cold reduction, and material thickness is 03-0.5 millimeter, and moisture content is 20%.
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 800 orders, and carbon content 97, gets 130kg.Batching: water-soluble wax is 60kg, clay 45kg, malt sugar 20kg, high-carbon black pigment 5kg.All material is stirred, mediate 3 hours, temperature keeps 30 degrees Celsius, and then cold reduction is 0.5 millimeter, and the material that moisture content is 20% 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 resin 4B lead for retractable pencil pencil by the technique of normal production Wood-bar pencil.
Example 2:
First prepare raw material: with pulverizing later Graphite Powder 99, fineness is 800 orders, and carbon content 98, gets 130kg.Batching: water-soluble wax is 70kg, clay 35kg, malt sugar 15kg, 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 20% 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 resin 4B lead for retractable pencil 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.
