Abstract
Description
(57) Reěení se týká zařízení pro ohřev plastických hmot na stanovenou teplotu konkrétně roztavení polymerů v průběhu výchozího formování. Cílem řešení je zatřízení, které umožní zpracování materiálu citlivého na teplo,, např. PVC, metodou výchozího formování. Přitom je nutno dosáhnout vysokou technologickou, stabilitu průběhu zpracování při nízkých nákladech, vysoké jakosti výrobků a zamezení zdraví škodlivých pracovních podmínek zajištěním dobrého tekutého stavu materiálu při krátkodobém tepelném zatížení· Podstata řešení spočívá v tom, že se plastická hmota zahřívá při využití disipačního jevu tak, že se mezi plastikátor a hrdlo umístí zařízení s jedním disipačním prvkem opatřeným štěrbinovými propustnými otvory. Řešení umožňuje zpracování, zvláště metodou odlévání pod tlakem, materiálů citlivých <ja teplo, jako např. PVC a zejména umožňuje zpracování hmoty se složitými tepelnými vlastnostmi metodou výchozího formování.(57) The present invention relates to a device for heating plastics to a specified temperature, namely the melting of polymers during initial molding. The aim of the solution is to provide a method that allows heat-sensitive material, such as PVC, to be processed by the initial molding method. It is necessary to achieve high technological, process stability at low cost, high product quality and avoid harmful working conditions by ensuring good liquid state of the material at short term heat load. The essence of the solution is that the plastic heats A device with a single dissipation element provided with slotted through holes is placed between the plasticizer and the neck. The solution allows processing, in particular by the die casting method, of heat-sensitive materials such as PVC and, in particular, allows the processing of mass with complex thermal properties by the initial molding method.
