Abstract
Przedmiotem zgłoszenia jest sposób czyszczenia i regeneracji form do przetwórstwa tworzyw sztucznych i ich elementów, zwłaszcza systemów gorąco-kanałowych charakteryzujący się tym, że czyszczenie zgrubne prowadzi się poprzez podgrzanie formy do temperatury od 470 do 500°C w komorze pojemnościowej bez dostępu powietrza i wygrzewa w czasie 2,8 do 3 h, w której zachodzi proces pyrolizy, po czym elementy systemu gorąco-kanałowego lub poszczególne płyty formy wtryskowej poddaje się myciu ultradźwiękowemu z falą ultradźwiękową o wibracji ultradźwiękowej wynoszącą 27 do 28 kHz. Następnie, prowadzi proces czyszczenia natryskiem granulatu z tworzywa sztucznego zawierającego mieszankę Duroplastu od 66 do 70% oraz Celulozy od 30 do 33% o gramaturze od 200 do 400 µm i twardości granulek od 54 do 62 Barcol pod ciśnieniem w zależności od stopnia zabrudzenia od 1 do 8 bar, strugą skupioną w atmosferze zamkniętej o wilgotności od 30 do 60% i temperaturze otoczenia 18 do 20°C, do uzyskania powierzchni pierwotnej.The subject of the application is a method of cleaning and regeneration of molds for processing plastics and their components, especially hot-channel systems, characterized in that rough cleaning is carried out by heating the mold to a temperature of 470 to 500 ° C in a capacity chamber without air access and heats up 2.8 to 3 hours, during which the pyrolysis process takes place, after which the elements of the hot-duct system or individual injection mold plates are subjected to ultrasonic washing with an ultrasonic wave with an ultrasonic vibration of 27 to 28 kHz. Then, it carries out the process of spraying plastic granules containing a mixture of Duroplast from 66 to 70% and cellulose from 30 to 33% with a basis weight from 200 to 400 µm and granules hardness from 54 to 62 Barcol under pressure depending on the degree of soiling from 1 to 8 bar, stream focused in a closed atmosphere with a humidity of 30 to 60% and an ambient temperature of 18 to 20 ° C, to obtain the primary surface.
