Stone Paper Production MachineGeneral situation:The
objective of the main products of environmental protection is a
waterproof paper, non-flammability, a new type of green
biodegradable material, the main raw material for calcium carbonate
powder and polymer materials, granulating, casting, coating process
to produce white green paper, after process of printing, folding,
binding, and then pasting, bronzing can be made into books,
magazines, handbags, environmental decorative paper, boxes, table
cloth, something like this. In line with the current low carbon,
environmental protection, energy saving, emission reduction,
sustainable development of the general trend.Product analysis:Stone
paper main raw materials for calcite and polyethylene, do not add
plasticizer and other toxic and harmful substances.Compared with
the traditional wood pulp paper, the production process of stone
paper does not need water, does not need to cut down trees, no
waste water, waste gas and solid waste emissions, the production
process of environmental protection;Stone paper can be degraded,
which is a pollution-free green environmental protection
project;With waterproof, moisture-proof, tear resistance, anti -
folding, insect-proof, direct contact with food and other excellent
properties.Stone paper can be used to replace cultural paper,
industrial paper, packaging paper and other aspects.It is an
environmentally-friendly material recognized by international
general standards.Process flow:Step 1--Plastic Compound Pelletizing
process: raw material calcium carbonate powder, polyethylene
(HDPE/LDPE), polypropylene (PP) and additives are mixed in a
certain proportion, and then processed through high pressure
mixing, extrusion, hot cutting, cooling and air separation to
produce EPM raw material particles with uniform appearance.Step
2--Casting process: heat EPM raw material particles to melt
state, extrude them from the "T" mold head into sheets, and through
piecewide unidirectional stretching, cooling, solidification,
shaping, filling, thin EPM semi-finished film material can be
prepared.Measurement and surface treatment.The thickness of the
material produced by this process is between 60μm and
120μm.Induction process: after corona, leveling, positive and
negative double-sided filling and calendering, semi-finished EPM
films or sheets can be rolled up to obtain EPM finished materials
of different specifications.Step 3---Coating Machine:The stone
paper base paper produced by the casting method is coated, firstly,
the coating liquid is prepared according to the formula and then
coated and produced on a coater, and the device is coated by a
rotary reverse method. By forming reverse velocity difference
between paper surface and coating roll erand coating feeding
roller, to achieve uniform coating and stable adhesion to the paper
surface. After drying in an oven, repeat the same operation to coat
the back side of the paper, and finally stabilize the constant
tension. The finished stone paper roll can be obtained by winding
up.Step 4---Printing Machine:Step 5--Cutting and trimming
process: the EPM material produced by the above process is cut
into flat plate general specifications for printing plants to
facilitate the printing production of lithographic offset press and
other equipment.Machine Size and Model: Equipment
