Abstract

Disclosed is a graphite carbon lead 4B processing method. The method is characterized by including the following steps: (1) crushing flake graphite into graphite powder with the particle size of 650 meshes and with carbon content of 80-86; (2) putting 35-45kg of water soluble wax, 35-40kg of clay and 10-15 kg of high color black in 95kg of major material; (3) uniformly stirring the materials in the step (2), and putting the materials in a kneader for kneading for 3-4 hours; (4) performing cold rolling on the kneaded materials to enable the material thickness to be 0.3-0.5mm; (5) putting the rolled materials in a storage tank for storing for 72 hours for standby application; (6) putting the materials in the step (5) in a lead pressing machine to press a certain size of smooth graphite pencil leads. The method has the advantages that the technology is simplified and improved on the basis of an existing technological process, but machinery equipment and the like are not improved, so that the method can be directly applied to existing production technology and is simple and easy to implement.

Description

A kind of graphite 4B carbon element core processing method

Technical field

The present invention relates to pencil manufacture field, relate in particular to a kind of graphite 4B carbon element core processing 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 instructions for use of beginner and wild 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 processing method of a kind of graphite, its objective is and utilize modern pencil process technology, take 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 4B carbon element core processing method, it is characterized in that comprising the following steps:

(1) crystalline flake graphite is ground into graphite powder, order number is 650 orders, and phosphorus content is 80-86;

(2) in major ingredient 95kg, place water-soluble wax 35-45kg, clay 35-40kg,, high-carbon black pigment 10-15kg;

(3) material of step (2) is stirred, be placed on and in kneader, mediate 3-4 hour; Temperature 35-40 degree Celsius;

(4) by the material cold reduction after mediating, make its material thickness at 03-0.5 millimeter, moisture content is 13%;

(5) material rolling is placed in holding 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.

The good effect of invention is: the present invention is take graphite powder as basis, selects reasonably formula, by the production technology of science, adopts production and 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 technical process basis, machinery equipment etc. is not improved, therefore can directly apply in existing production technology, simple.

Specific embodiment:

Example 1:

First prepare raw material: with pulverizing later graphite powder, fineness is 650 orders, and phosphorus content 80, gets 95kg.Batching: water-soluble wax is 40kg, clay 45kg, 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 13% is placed in holding 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 4B carbon element pencil by the technique of normal production Wood-bar pencil.

Example 2:

First prepare raw material: with pulverizing later graphite powder, fineness is 650 orders, and phosphorus content 85, gets 95kg.Batching: water-soluble wax is 40kg, clay 40kg, high-carbon black pigment 15kg.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 holding 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 4B 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 (2)
