3. push banded mixture: powder after will pulverizing or particle are pressed in the extrusion die, the temperature of heating is 160-180 ℃, mix compacting in mould compresses and is squeezed into banded mixture, the cut-out pressure of mold closing is 100-200bar, when the PE base, the PP base plastic waste that use based on polyolefin, or ABS is when being the plastics on basis and the compounding substances of ABS waste material, banded mixture is 150 ℃-195 ℃ to the interior stream temperature of blank product moulding pipe, offer the taking-up that the next banded mixture pressure of handling is used for the blank section bar, this pressure is 10-300bar.
4. forge and press the blank section bar: the banded mixture that will squeeze out enters in the blank product moulding pipe, along banded mixture axis direction forging and pressing, up to this moulding pipe be full of fully and shrink through recirculated water cooling harden into around wall thickness be 7-9cm, outside wall thickness is 12-16cm, the middle part is the blank section bar of hollow shape, length is 0.5-6m, then the moulding pipe is taken out from the blank section bar.
5. machining moulding: blank section bar after will hardening periphery machining, the hollow sectional shape that is made into specification are the hollow build material of square type, positive square, round, polygonal, special-shaped through hole.
6. coating: select for use suitable central tube to deliver in the coating pipe on the hollow build material erection work face with the machining moulding, after by the cooling bath sclerosis, carry out the smooth coating of vacuum, it is 0.1-2.0mm that clad material is selected thickness for use, based on the sheet of moulding of polyacrylate (PMMA), polyolefin, ABS, clad material can mix with coloring matter.
7. the coating that belongs to covered with gold leaf: at the inside and outside surperficial pressure roller binding metal coating of hollow build material; can select thickness for use is the colorful aluminum foil of 0.1-1.0mm; or have decorative layer or with the aluminium foil of baking vanish layer; the baking vanish layer is selected the dusty material of uvioresistant, high temperature resistant sour polyester carboxylate resin for use; metal coating cover the periphery of hollow build material or blank section bar and or the periphery of semiproduct section bar, be pasted with diaphragm on the metal coating surface.
Described 1. selection batching: select wood fiber and waste and old cardboard for use, as straw, flax, ramie, bar stem, the combined ingredient of any one or more of waste crop materials string and first kind of well-mixed batching of batching, its weight percentages of components is: second kind of batching 1-20%, and all the other are first kind of batching; Before mixing, second kind of batching should be dried to residual moisture weight and be less than 3%, is preferably to be less than 1%.
The positive beneficial effect that the present invention had:
1. select the natural salvage material that does not destroy ecological resources for use, do not contain noxious materials such as PVC, what can digest in the big or middle municipal refuse disposal area that overstock a large amount of have sorted out mixes waste plastics etc., thereby the environment pollution of having avoided burning or landfill to cause, for the waste plastic that occupies larger proportion in municipal refuse has found the best approach that utilizes again, the recyclable recycling of waste and old section bar is used, and can not cause new pollution to environment;
2. do not consume the ecological, environmental protective resource, discarded wood fiber that is added or sponge wide material sources, inexpensive, light weight, little to equipment attrition, can process repeatedly, can biodegradation, for waste crop materials opened up one turn waste into wealth newly by way of;
3. the batching of being made up of the thermoplasticity waste or used plastics also can add the batch mixes compacting that a little wood fiber and string are formed, and after plastics melt and reharden, will show the good powerful feature that adds, and can reduce section bar weight and improve section bar intensity;
4. behind the extruding semiproduct, through recirculated water cooling, a large amount of contractions are finished, after machining, remaining amount of contraction be not enough to between sash and the window frame or the interaction between window frame and the masonry structure produce bigger influence;
5. the blank core body that adopts the meticulous powder that pulverizes to make has less processing resistance, can strengthen modulus of elasticity, bending strength in the body of wall, statics structure organizations such as case hardness;
6. section bar is a hollow-core construction, and the energy in extruder consumes less, energy conservation;
7. technology of the present invention is simple, with short production cycle, and cost of manufacture is low, is applicable to that the building door window profile makes, also applicable to making such as house section bar and packaging material, backing plates.
