Embodiment 1
[0034] (1), raw material processing:
[0035] Furfural resin is used as raw material, placed in a constant temperature drying oven, and the temperature is respectively selected at 50°C or 60°C or 70°C or 80°C or 90°C or 100°C, followed by drying for 2h or 3h or 4h or 6h or 10h, and the drying The final high molecular polymer is pulverized to particles below 1.5cm with a pulverizer, and the high molecular polymer after pulverization does not reach the required particle size, and is further finely pulverized with a ball mill or an air mill to obtain a particle size of 1 micron or 3 micron or 5 micron or 7 micron particles;
[0036](2), forming:
[0037] Mix the finely pulverized high molecular polymer with the binder and additives in a mass ratio of 1:1:0.1 or 1.5:1:0.1 or 2:1:0.1 or 2.5:1:0.1, and the binder It is acrylamide or polyvinyl alcohol or carboxymethyl cellulose or phenolic resin or lignin, and the auxiliary agent is starch or triethanolamine or polyethylene glycol....

[0046] (1), raw material processing:
[0047] Use furfural resin as raw material, put it in a constant temperature drying oven at a temperature of 55°C or 65°C or 75°C or 85°C or 95°C or 120°C, dry for 1h or 5h or 9h or 14h or 18h, and dry the high Molecular polymers are crushed with a pulverizer to particles below 1.5cm, and the crushed high molecular polymers cannot reach the required particle size. They are further finely pulverized by ball milling or air milling to obtain particle sizes of 2 microns or 4 microns or 6 micron or 8 micron particles;
[0048] (2), molding:
[0049] Mix the finely pulverized high molecular polymer with binder and auxiliary agent in a mass ratio of 1.2:1:0.1 or 1.7:1:0.1 or 2.5:1:0.1 or 2.9:1:0.1, and the binder It is acrylamide or polyvinyl alcohol or carboxymethyl cellulose or phenolic resin or lignin, and the auxiliary agent is starch or triethanolamine or polyethylene glycol. It is extruded with a hydraulic press and the molding pressure i...

[0058] (1), raw material processing:
[0059] Use urea-formaldehyde resin as a raw material, put it in a constant temperature drying oven at a temperature of 70°C or 80°C or 90°C or 100°C or 110°C or 120°C, and dry it for 2 hours or 4 hours or 6 hours or 8 hours or 10 hours. Molecular polymers are crushed to particles below 1.5cm with a pulverizer, and the crushed polymers do not reach the required particle size. They are further finely pulverized by ball mills or air mills to obtain particle sizes of 2.5 microns or 4.5 microns or 6.5 micron or 8.5 micron particles;
[0060] (2), molding:
[0061] Mix the finely pulverized high molecular polymer with binder and auxiliary agent in a mass ratio of 1.1:1:0.1 or 1.5:1:0.1 or 2.4:1:0.1 or 2.7:1:0.1, and the binder It is acrylamide or polyvinyl alcohol or carboxymethyl cellulose or phenolic resin or lignin, and the auxiliary agent is starch or triethanolamine or polyethylene glycol. It is extruded with a hydraulic press and the mo...
