Abstract
The utility model relates to the technical field of high polymer material processing equipment, in particular to processing equipment for chlorinated polyvinyl chloride boards. An existing extruder is modified by changing a conical head screw into a round head screw and changing a vacuumizing device into two vacuum pumps. 30-millimeter super-thick chlorinated polyvinyl chloride extruded boards manufactured by the processing equipment are particularly applicable to industries with higher requirements on physical and mechanical properties and chemical stability performance of materials, such as chemical industry, petroleum, electroplating, water purification treatment equipment, extraction box engineering, chemical tanks and the like.
Description
Technical field
[0001] the utility model relates to the processing of high molecular material equipment technical field, especially designs a kind of process equipment of chliorinated polyvinyl chloride sheet material.
Background technology
[0002] CPVC plastics extrusion board is a kind of new material; Be to utilize expressing technique to process by the CPVC resin, because the scrambling of CPVC plate molecular link increases, polarity increases; Make the increase of dissolving resin property; Chemical stability increases, thereby has improved the corrosion such as hear resistance, acid and alkali resistance, salt, oxidant of material, has improved the mechanical performance of the heat distortion temperature of resin.Compare with general plastic plate, have better high temperature resistant, excellent corrosion resistance, dimensionally stable, be easy to process, splendid characteristics such as anti-flammability, can be applied in the higher industry of physical and mechanical properties and chemical stability requirement
.
But CPVC resin chlorinty is high, and processing ratio of viscosities PVC doubles at least, and CPVC density is big, has determined its difficulty of processing to improve, and concerning some especially big containers, because its thickness is big, difficulty of processing is bigger, very easily scraps especially.In view of the superior physical and chemical performance of CPVC, CPVC sheet material more is applicable to makes super-huge container, like acidproof storage tank etc., need have bigger mechanical strength and rigidity, improves its temperature tolerance, strengthens the ability of ageing-resistant decomposition.But it is limited in one's ability that the CPVC of China's production at present extrudes slab; Existing the thickest homemade CPVC sheet material is by what the tame plastic molding and processing plant in Jiangsu one produced 25mm only to be arranged; The thicker whole dependence on import of CPVC slab can not satisfy the industry needs of higher material performance requirement such as domestic vast chemical industry, oil, plating, water purification apparatus, extraction box engineering, chemicals tank, container.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical defective, and promptly existing homemade CPVC plate thickness is low, and the thickest is 25mm, can't satisfy the needs of high-performance slab demand industry; A kind of process equipment of chliorinated polyvinyl chloride sheet material is provided, uses this equipment can produce 30 millimeters ultra thick chliorinated polyvinyl chloride sheet materials.
The technical scheme of the utility model is: the outlet of high-speed mixer 1 connects low temperature cold mixer 2; Low temperature cold mixer 2 connects stock chest 3, and stock chest 3 is connected with extruder 4 through pipeline, and the extruder barrel inner chamber is divided into four isometric districts; Wherein 1 district is a feeding section; 2,3 districts are the compression section, and 4 districts are homogenizing zone; The lower end, compression section of extruder 4 is provided with vacuum extractor 8, and this vacuum extractor 8 comprises two vacuum pumping pumps, and the right side port of export of extruder 4 is provided with calender 5, and calender 5 right-hand members are provided with draw-gear, and draw-gear 6 right-hand members are provided with cutter sweep 7; Wherein said calender 4 is a three-roller calendar; Described draw-gear comprises deflector roll and two carry-over pinch rolls, and carry-over pinch rolls are settled up and down, and sheet material via getting into cutter sweep 6 in the middle of two carry-over pinch rolls, obtains finished product sheet material through deflector roll; Screw rod end in the machine barrel of wherein said extruder is the hemisphere shape.
Because it is more to produce HCL gas in the CPVC process, selects the strong screw rod of corrosion resistance, and on an original pumped vacuum systems basis, a vacuum pumping pump is added in repacking, and exhaust effect is better, more helps producing the CPVC slab.
The original-pack corollary equipment of extruder is the conical head screw rod, when producing the 30mmCPVC slab, and the smooth inequality of product, and be attended by great amount of bubbles, product is shapeless.Use the globular model screw rod instead, changed melt material the screw rod least significant end liquid form, shear action and the change in torque of storeroom are more adapted to before terminal mould to the moulding effect of material, make extrusion board smooth evenly.The extruder barrel heating is divided into four districts, and screw rod is installed in the machine barrel, again screw rod is divided into feeding section according to the state variation degree of resin in machine barrel; Compression section, homogenizing zone three parts, an original-pack supporting pumped vacuum systems are between three districts, two districts of barrel heating; The compression section of screw rod; In order to strengthen exhaust capacity, more help the extrusion molding processing of CPVC slab, adorned a vavuum pump again at the opposite side that original-pack supporting vavuum pump is connected with barrel; Strengthened exhaust effect greatly, made the extrusion board quality obtain good raising.And two the cover vacuum plant use simultaneously and not only strengthen exhaust effect, if stopping up appears in a cover vavuum pump in process of production, another set of can also working on when stopping to clear up can not cause pumped vacuum systems to be stagnated.
The beneficial effect of the utility model is:30 millimeters ultra thick chliorinated polyvinyl chloride extrusion boards that device fabrication through the utility model goes out are particularly useful for chemical industry, oil, plating, water purification apparatus, extraction box engineering, chemicals tank etc. to Material Physics mechanical performance and the higher industry of chemical stability requirement.
