Композиционният материал се изготвя, като се смесват графитен прах, смола и етилов алкохол в съд със S-образна бъркалка. Получената смес се суши, след което се гранулира и пресова.The composite material is prepared by mixing graphite powder, resin and ethyl alcohol in an S-shaped vessel. The resulting mixture was dried, then granulated and pressed.
Изготвените изделия с композиционния материал съгласно полезния модел са устойчиви на въздействието на горещи и химически агресивни флуиди и имат ниска порьозност под 1 %·Composite articles manufactured according to the utility model are resistant to the effects of hot and chemically aggressive fluids and have a low porosity of less than 1%.
Примерно изпълнение на полезния моделExemplary implementation of the utility model
Количеството на пресматериала се из числява според обема на желания детайл, като се има предвид плътността на графитсъдържащия композиционен материал.The quantity of the material is calculated according to the volume of the desired part, taking into account the density of the graphite-containing composite material.

Смесват се чрез разбъркване финодисперсен графитен прах с размер на частиците под 150 mm в количество 8,4 kg, 3,0 kg фенолформалдехидна смола /50 %/, 4,0 kg етилов алкохол /95 %/ и 180 kg хексаметилентетрамин като катализатор, в хомогенизатор със S-образна бъркалка в продължение от 10 до 48 h. Получената смес се суши на въздух от 48 до 120 h. Изсушеният материал се гранулира през сито с размер на частиците 1 mm. Гранулатът се суши в термошкафове при температура от 60 до 80°С, не по-малко от 48 h. Изсушеният гранулат се пресова в нагрявани метални пресформи при температура 150 до 170°С, налягане 250 до 300 kg/cm2 и време на задържане 10 до 30 min.EXAMPLE 1 Finely dispersed graphite powder with particle size less than 150 mm in an amount of 8.4 kg, 3.0 kg phenol formaldehyde resin (50%), 4.0 kg ethyl alcohol (95%) and 180 kg hexamethylenetetramine as catalyst, in an homogenizer with an S-shaped stirrer for 10 to 48 hours. The resulting mixture was air-dried for 48 to 120 hours. The dried material was granulated through a sieve with a particle size of 1 mm. The granulate is dried in ovens at 60 to 80 ° C for at least 48 hours. The dried granulate is pressed into heated metal molds at a temperature of 150 to 170 ° C, a pressure of 250 to 300 kg / cm 2 and a retention time of 10 to 30 minutes.
