Abstract
The invention discloses a processing method of graphitized HB pencil lead. The processing method comprises the following steps of 1, taking first-order talcum powder of 1800 meshes for next use, 2, putting 25-35kg of calcium carbonate, 15-25kg of a binder, 10-18kg of polymerized wax and 20-15kg of a pigment into each 85kg of the main material, 3, stirring the materials blended by the step 2 to obtain a uniform mixture, 4, rolling the kneaded materials by a roller, 5, putting the rolled material into a storage tank and carrying out storage for 72h for next use, and 6, pressing the material obtained by the step 5 through a core compressor to obtain the graphitized HB pencil lead having a certain specification. The processing method simplifies the existing technology, is free of large-scale equipment improvement, can be directly used for the existing production technology and is simple and easy.
Description
Technical field
The present invention relates to pencil manufacture field, relate in particular to a kind of leadization HB lead for retractable pencil working method.
Background technology
Now, drawing in the world crayon is mainly to use toner rod, due to soft, is easy to fracture, and adds not packing of outside, is easy to pollute; Next is expensive, and few people are using always at home.Since the thick and heavy agile sense that has again watercolor painting of the existing oil painting of crayon, painting effect uniqueness.Earlier 1900s, Lee's cheese imported China into crayon, and crayon is also slowly grown up in China, but owing to being to be that raw material is soft with mineral raw material always, was easy to fracture not portable, and market is always depressed.
Summary of the invention
The present invention seeks to the defect for prior art, the working method of plumbousization lead for retractable pencil is provided.Its objective is the processing technology of utilizing modern pencil, take talcum powder as main raw material, through other materials batching, produce a kind of leadization HB lead for retractable pencil working method, realize the transformation of pencil high added value.
The present invention is achieved through the following technical solutions, and has developed a kind of leadization HB lead for retractable pencil working method, it is characterized in that comprising the following steps:
(1) be 1800 orders by one-level talcum powder order number, with for subsequent use;
(2) in major ingredient 85kg, place calcium carbonate 25-35kg, adhesion agent 15-25kg, pigment 20-15kg, polymer wax 10-18kg;
(3) material in step (2) is stirred;
(4) kneaded material being gone out to thickness with roll squeezer roll-in is 0.2-0.5 millimeter;
(5) put the good material of roll-in into hold-up vessel and store 72 hours, with for subsequent use;
(6) by the lead lead for retractable pencil of pressing core machine extrusion certain specification for the material of step (5).
In described step (3), kneader is mediated 3-4 hour, and temperature is 30-45 degree Celsius.
The thin slice that described step (4) moisture content is 16.
Positively effect of the present invention is: the present invention is take talcum powder as major ingredient, be aided with formula accurately, by the production technique of science, adopt the technological method of common production lead for retractable pencil, develop a kind of new high grade colorful lead for retractable pencil, make the high added value of pencil further widen thinking.And because technique of the present invention is that in existing technological process, the upper simplification in basis is improved, machinery equipment is not improved on a large scale, first there is individual production technique so can directly apply to, simple.
Specific embodiment:
Embodiment 1:
First prepare major ingredient: fineness is 1800 object talcum powder 80kg.In major ingredient 85kg, place calcium carbonate 25kg, adhesion agent 20kg, pigment 15kg, polymer wax 20kg; (3) material in step (2) is stirred; Above material is stirred, mediate 3 hours, temperature is 30Shi degree, and then going out thickness with roll squeezer roll-in is 0.5 millimeter, the thin slice of moisture content 16, then carry out the storage of 72 hours, and finally extrude the lead lead for retractable pencil of Φ 5.0, dry, for subsequent use to do.
Embodiment 2:
First prepare major ingredient: fineness is 1800 object talcum powder 85kg.In major ingredient 85kg, place calcium carbonate 25kg, adhesion agent 30kg, pigment 15kg, polymer wax 15kg; (3) material in step (2) is stirred; Above material is stirred, mediate 3 hours, temperature is 35 degrees Celsius, and then going out thickness with roll squeezer roll-in is 0.5 millimeter, the thin slice of moisture content 13, then carry out the storage of 72 hours, and finally extrude the lead lead for retractable pencil of Φ 5.0, dry, for subsequent use to do.
In actual applications; those skilled in the art completely can be in technical field scheme of the present invention; in actual applications; those skilled in the art is completely in technical scheme of the present invention; other parameters of choose reasonable; 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)
1. a leadization HB lead for retractable pencil working method, is characterized in being to comprise the following steps:
(1) be 1800 orders by one-level talcum powder order number, with for subsequent use;
(2) in major ingredient 85kg, place calcium carbonate 25-35kg, adhesion agent 15-25kg, pigment 20-15kg, polymer wax 10-18kg;
(3) material in step (2) is stirred;
(4) kneaded material being gone out to thickness with roll squeezer roll-in is 0.2-0.5 millimeter;
(5) put the good material of roll-in into hold-up vessel and store 72 hours, with for subsequent use;
(6) by the lead lead for retractable pencil of pressing core machine extrusion certain specification for the material of step (5).
