Изобретение относитс к переработке термопластов и касаетс способа термообработки гранулированных лоливинилхлорлдных пластикатов, предназначенных дл кабельных изделий.The invention relates to the processing of thermoplastics and relates to a process for the heat treatment of granulated polyvinyl chloride plastic compounds intended for cable products.
Известен способ термообработки гранулированных поливинилхларндных пластвкатов в кип щем слое в cpeiAe теплоносител при 60-65° С.The known method of heat treatment of granular polyvinyl plasdate plastikatov in a fluidized bed in a heat carrier cpeiAe at 60-65 ° C.
Целью .изобретени вл етс улучшение физико-меха«и ческих ,и электрических свойств пластикатов, под1вергнутых термообработке. Дл достижени этой цели предлагаетс тер .мообработку осуществл ть ;нри 80-110° С в течение 30-60 мин.The purpose of the invention is to improve the physical and mechanical and electrical and electrical properties of the plastic compounds subjected to heat treatment. In order to achieve this goal, it is proposed that the treatment be carried out; at 80-110 ° C for 30-60 minutes.
П р и м е р. Термообработку провод т следующим образом. Материал, подлежащий термообработке, из бункера / шнековьш дозатором 2 вводитс IB камеру 3 на газораспределительную решетку 4.PRI me R. The heat treatment is carried out as follows. The material to be heat-treated is fed from the hopper / screw-dispenser 2 with an IB chamber 3 to the gas distribution grid 4.
Засасываемый вентил тором воздух нагреваетс в калорифере 5 и, войд в камеру 3 снизу, воздействует на материал, интенсивно перемешивает его и нагревает до 80- 110° С.The air drawn in by the fan heats up in the heater 5 and, entering the chamber 3 from below, acts on the material, intensively mixes it and heats up to 80-110 ° C.
По окончании процесса термообработки открываетс затвор 6 и М:атериал выводитс в бункер черв чного лресса или иную емкость. Обработанный воздух - теплоноситель, - проход через циклон 7, очищаетс в нем и выбрасываетс в атмосферу.At the end of the heat treatment process, shutter 6 and M are opened: the material is brought to a hopper or another container. The treated air, the coolant, passes through the cyclone 7, is cleaned therein and is released into the atmosphere.
Термообработанный пластикат нанос т на кабель. Оболочка получаетс монолитной (без пор) с гладкой блест щей поверхностью и обладает следующими свойствами: Разрушающее напр жениеHeat treated plastic is applied to the cable. The casing is monolithic (without pores) with a smooth, glossy surface and has the following properties: Breaking stress
