Plastic refractories

Plastic refractories
THERVEK RM（Ramming）

Clay bonded ramming refractory with superior resistance to thermal spalling

• Plastic ramming refractory consisting of carefully selected refractory aggregate and highly-pliable clay, adjusted into a workable form with the addition of moisture. The product is supplied in 50mm-thick slices.
• Place slices of the product in the form, and apply to the refractory lining walls by ramming them firmly into place with a pneumatic rammer. Prepare forms for ramming application.
• Clay bonded plastic refractories maintain their shape after ramming due to the adhesive power of the clay. After firing, gives the refractories their strength (i.e. heat setting).

Characteristics

• Plastic refractories do not require mixing, and can be rammed as they are.
• Clay bonded plastic refractories offer superior resistance to thermal spalling.

THERVEK HR（Plastic gunning）

Clay bonded plastic gunning refractory with superior resistance to thermal spalling

• Plastic gunning refractory consisting of carefully selected refractory aggregate and highly-pliable clay, adjusted into a workable form with the addition of moisture. The product is supplied in granular clay-like form.
• Using AGC Plibrico’s independently developed specialized gunning machine (HyRATE unit), it is now possible to apply plastic refractories by gunning (HyRATE method), achieving a drastic improvement in installation efficiency in comparison with ramming.
• Clay bonded plastic refractories maintain their shape after ramming due to the adhesive power of the clay. After firing, gives the refractories their strength (i.e. heat setting).

Characteristics

• Gunning significantly increases application efficiency in comparison with ramming.
• Clay bonded plastic refractories offer superior resistance to thermal spalling.

THERVEK PAT（Patching）

Patching repair material with superior adhesive properties

• Plastic refractory for patching use, consisting of a combination of carefully selected refractory aggregate and phosphate binder, adjusted into a workable form.
• Patching refractories are adjusted to a softer consistency than ramming plastic refractories, and used for repairing small-scale damaged sections of refractory lining walls by patching (i.e. manual filling).
• After application, patching refractories are fixed in place by the strong adhesive power of phosphate. When these refractories are heated to temperatures in excess of 350℃, a phosphate condensation reaction occurs, significantly improving the strength of the refractory (i.e. heat setting).

Characteristics

• These refractories are affixed firmly to the repair area by the strong adhesive power of phosphate.
• After heating, patching refractories display extremely strong adhesive strength in their adhesion to the base material.
• Patching in this way enables you to prolong the service life of your refractories by performing easy repairs.
