A base material for a disk roll, the base material including: 5 to 9 wt % of ceramic fibers, 20 to 40 wt % of kibushi clay, 2 to 20 wt % of bentonite and 40 to 60 wt % of mica.

The present invention relates to a continuous manufacturing method for a vacuum insulation material, including: a first step of putting a porous insulation material into an inner envelope having permeability, three sides thereof being closed and one side thereof being open, and then sealing the inner envelope; a second step of flattening an upper broad side of the inner envelope; a third step of compressing the inner envelope flattened in the second step; a fourth step of sealing all sides of the inner envelope compressed in the third step, except for one side, with an outer envelope having a shielding property, and packaging the sealed inner envelope; and a fifth step of sealing the one side of the inner envelope not sealed in the third step by putting the inner envelope sealed in the fourth step into a vacuum chamber and performing a vacuum operation.

Disclosed is a method for preparing graphite film, comprising steps as follows: 1) winding; 2) carbonizing at a low temperature; 3) graphitizing at a high temperature; 4) unwinding and feeding, winding up the electrographite film semi-finished product and flexible graphite paper separately; 5) calendaring to press the electrographite film semi-finished product against release film or protective film; 6) winding up and packaging. The winding process comprises steps as follows: a. winding high temperature resistant elastic material around the graphite cylinder core; b. bonding macromolecular film to flexible graphite paper, and then winding around the graphite cylinder core based on step a; c. when the macromolecular film and flexible graphite paper wound in step b reach the predetermined thickness, securing with carbon cord.

A stretching and conveying device for a green compact includes a first roll and a second roll structured to convey by rotation the green compact by sandwiching the green compact between the first roll and the second roll and stretch the green compact using a circumferential speed difference between the first roll and the second roll. The second roll has a curvature radius larger than a curvature radius of the first roll, and is positioned downstream of the first roll. The green compact is conveyed while being supported on a circumferential surface of the first roll, delivered to the second roll side at a position where the first roll and the second roll face each other, and conveyed while being supported on a circumferential surface of the second roll.

A production method is provided. The production method comprises forming material by pressing or pulling ceramic material through a channel of an extrusion die, said channel being at least partly defined by the lateral surface area of at least one rotating die, and heat processing the formed material to form a ceramic product.

A method for cleaning a ceramic matrix from a compaction roller includes steps of: (1) applying a cleaning fluid to the compaction roller; (2) scrubbing the compaction roller to remove ceramic particles of the ceramic matrix from a compaction-roller surface of the compaction roller, and (3) drying the compaction roller to remove the cleaning fluid from the compaction-roller surface.

A method for compacting a ceramic composite material includes steps of: (1) positioning a roller in contact with a ply-surface of a ply of the ceramic composite material, wherein the ply is positioned on a compaction-surface; (2) applying a compaction pressure to the ply using the roller such that the contact pressure is substantially uniformly distributed on the ply; and (3) with the roller in contact with the ply-surface and applying the compaction pressure, moving the roller across the ply to conform the ply to the compaction-surface.

The present invention relates to a method (900) for producing artificial stone slabs comprising grinding (901) an inert material comprising silicates having an aluminium oxide content greater than or equal to 25% by weight, until a mixture of granulated material is obtained in which a coarse fraction of granules, having a diameter greater than 300 m, is 70% by weight of the total weight of the mixture. The method (900) further comprises spraying and drying (902) a suspension comprising the granulated material by means of an atomizing device until an atomized material is obtained. Furthermore, the method comprises depositing (903) the atomized material on at least one movable surface of a compacting device and compacting (904) the atomized material on the movable surface, to obtain a slab of compacted material. The method (900) further comprises heating (906) the slab of compacted material to a temperature between 50 C. and 1250 C., for a time period of less than or equal to 45 min and greater than or equal to 10 min, to obtain a slab of consolidated material.
