PLANT FOR THE PRODUCTION OF DURABLE PLASTICS (PUTTIES) FOR SEALING WITH IMPROVED SEALING PROPERTIES, PARTICULARLY FOR USE IN CIVIL ENGINEERING

摘要

Invention herewith described refers to the plant for the production of durable plastics (putties) for sealing with the improved sealing properties, particularly for use in the civil engineering, that consists of the balance (1) for the preparation of the binder and the balance (3) for measuring the connective semi-finished product (c) and components (df), then of the planetary mixers (2, 4, 6), the unit (5) for chalk adding (h) and components (i-k), devices (7, 8) for the profiling of the pasty mass (l), devices (9) for cutting and unit (10) for cut off weight packing, and they are all linked with a conveyor belt (12).The technological process for production of durable plastics (putties) consists of two phases. During the first phase, the phase of the binder production, the measurement of plasticizers is performed which can be: paraffin oil, naphthenic oil, di-(2-ethylhexyl) phthalate, dibutyl phthalate, butyl benzyl phthalate, diisononyl phthalate, di-isodecyl phthalate, triethyl citrate and di-n-octyl phthalate or any combination thereof, component (b), polyethylene oligomer, component (a) which, after weighing on the balance (1), are transported to the planetary mixers (2) where the binder is mixed and the binding semi-finished product (c) is obtained.The manufacturing process of binders based on polyethylene oligomers proceeds with measuring of the binding semi-finished product (c), dispersant (d), homogenizers (s) and pigment on the balance (3) and after that the components are via belt conveyor (12) supplied to the mixer (4) for mixing and homogenizing the mass in order to obtain the binder (g).During the second phase, the binder (g) is via conveyor (12) delivered to the mixer (6) into which is from the unit (5) added the chalk (h) twice, talc (i), silicates (j) and other fillers according to the to defined technology.Directly from the mixer (6), the mass (l) enters the device (7) for plastic profiling. From the profiling device (7) there comes out the plastics of the defined profile which is cut by the cutting device (9), and then packed in the device (10) for packing the finished plastic products of a defined shape.
