摘要:
A multi-zone cementitious product, which includes a base zone made of a first cementitious material composition and forming a portion of the product. At least one facing zone is adjacent to and bonded to the base zone, the facing zone made of a second cementitious material composition and forming at least one exterior face of said product which is visible when the product is installed. A disrupted boundary layer is between the facing zone and the base zone, and includes material from both the facing zone and the base zone. The disrupted boundary layer bonds the facing zone to the base zone. The facing zone has a thickness sufficient to prevent the base zone from being visible when the product is installed.

A roll press machine according to the present disclosure includes a hot press mechanism having a pair of rollers arranged with a gap therebetween and heating mechanisms that heat the pair of rollers to heat and roll a forming material, a material feeding mechanism that feeds the forming material and a conveying mechanism that conveys the forming material fed by the material feeding mechanism to the hot press mechanism, in which each of the pair of rollers in the hot press mechanism has a roller structure including an outermost layer and an intermediate layer inside the outermost layer, and a thermal expansion coefficient of the outermost layer is lower than a thermal expansion coefficient of the intermediate layer.
摘要:
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 shaped article for use in a separation device may be produced by forming a batch mixture that includes filler material, fibrous material, and an inorganic binder, and shaping the batch mixture into a shaped structure. The fibrous material may have a D50 of greater than or equal to about 4 microns. The batch mixture may include greater than or equal to about 60 parts by weight and less than or equal to about 98 parts by weight of filler material, greater than or equal to about 2 parts by weight and less than or equal to about 40 parts by weight of fibrous material, and greater than or equal to about 10 parts by weight and less than or equal to about 50 parts by weight of inorganic binder per 100 parts by weight of the sum of the filler material and fibrous material, respectively.
摘要:
A device (1) for producing a slab (9) from artificial stone material by means of a double-belt press having a lower belt (2) and an upper belt (3), the double-belt press comprising a charging device (4) for loading a starting material for producing the slab (9) onto the lower belt (2), and the charging device (4) comprising at least one drum (5, 6) that is rotatable about its longitudinal axis (a1, a2).
摘要:
A method is disclosed for producing structures having a plurality of stems extending away from a fenestrated base to undercut islands projecting over fenestrations in the base. Such structures include slidingly-engaging fastener portions, self-engaging fasteners, uni-directional stepped fasteners, fastening segments integral with larger product components, and other structures with similar aspects. The method includes providing a set of partially bypassing dies to define a fenestrated common cavity contiguous with pluralities of undercut stem chambers and a terminal chamber, filling the cavity with a ductile moldable material, engaging the dies, and releasing the resultant product.
摘要:
The invention relates to a pellet press for producing pellets (10), there being in the pellet press (3) at least one die (4) having a multiplicity of holes (13) for compressing the biomass (1), at least one roll (5) rolling on the die (4) and at least one drive device for the die (4) and/or the roll (5). The aim of the invention is to produce a pellet press in which it is possible to eliminate local damage or partial wear of the die with the least possible effort or to make it easier to replace the die with a spare part. The invention consists of at least two die segments (7, 7′ . . . ) being arranged as the die (4), at least one supporting device (9) being arranged to support the die segments (7, 7′ . . . ) with respect to the roll (5), and the supporting device (9) having at least one aperture (8) for the pellets (10) emerging from the holes (13) in the die (4) to be led through.
摘要:
A manufacturing apparatus of display element is provided in which the position of a drive circuit or thin-film transistor on a flexible substrate roll can be confirmed easily. The manufacturing apparatus of display element (100) is provided with a supply roll (RL) that feeds a flexible, elongated substrate (FB) which has been wound into a roll shape in a first direction; a mold (10) that, by pressing onto the fed elongated substrate, forms at least one first index mark (AM) for one row of display elements and partition walls (BA) for a plurality of display elements (50) that are lined up in a second direction which intersects the first direction; and a droplet applying section (20) that applies droplets onto a groove portion formed between the partition walls.
摘要:
An apparatus and method for forming a clay slab includes a frame, a front panel supported on the frame and a rear panel supported on the frame. An outer cable is attached to the rear panel at one end and to the rear panel and to the front panel at another end. A rotatable drive axle is configured to simultaneously wind and unwind the outer cable and thereby move the front panel and the rear panel from an initial position to an intermediate position to draw a block of prepared clay into a gap defined by the front panel and the rear panel. The drive axle is further configured to simultaneously wind and unwind the outer cable in the opposite direction and thereby move the front panel and the rear panel from the intermediate position back to the initial position to remove the clay slab from the slab roller.
