摘要:
A fire-resistant material according to an example of the present disclosure includes a base material and at least one of a siloxane polymer and a phosphonate polymer. A method of making a fire-resistant material is also disclosed. In one example, a load bearing assembly (26) includes a plurality of elongated cord tension members (32) and a polymer jacket (34) comprising a fire-resistant material.
摘要:
The subject matter of the invention is a method for vulcanizing an article (10) formed from an elastomeric material, in which the article (10) is introduced into a vulcanizing press (11) in such a way that, during a vulcanizing operation, the article (10) is arranged between a first heatable pressure plate (12) and a second heatable pressure plate (13) of the vulcanizing press (11), and in which, in addition to the article (10), a first intermediate element (14) and a second intermediate element (15) are introduced into the vulcanizing press (11) in such a way that, during the vulcanizing operation, the first intermediate element (14) is arranged between the first heatable pressure plate (12) and a first side face (16) of the article (10) and the second intermediate element (15) is arranged between the second heatable pressure plate (13) and a second side face (17) of the article (10) that is opposite from the first side face (16), wherein, before they are introduced, the intermediate elements (14, 15) are provided with a releasing agent (28).

摘要:
A method of making an open-ended, reinforced, layered belt is disclosed. The method includes extruding a top layer onto said cords and meterering it into a first cavity or into a first gap defined by a smooth cylindrical mandrel and a molding band or a first gap defined between said mandrel and a laminating roller, thereby forming a carcass comprising said cords embedded at one surface of a film of said top layer material and training said carcass on a second portion of a cylindrical mandrel, said second portion including a second cavity defined between said cylindrical mandrel and a molding band or a second gap defined between said cylindrical mandrel and a laminating roller.
摘要:
The invention relates to a rubber mixture, particularly for vehicle tires, straps, and belts. In order to solve the conflict between rupture resistance and heat buildup, the rubber mixture is characterized by the following composition: 50 - 95 phr of at least one natural or synthetic polyisoprene and -5 - 50 phr of at least one butadiene rubber, and 0 - 30 phr of at least one styrene butadiene rubber, and 0 - 45 phr of at least one further polar or non-polar rubber, and 1.5 - 7.5 phr amorphous silicic acid, and/or precipitate silicic acid, and 25 - 80 phr of at least one carbon black having an iodine number between 80 - 300 g / kg and a DBP number between 115 - 200 cm3 /100g and 0.1 - 5 phr of at least one plasticizing oil and 2 - 100 phr of further additives.
摘要:
Continuous moving walkway comprising a continuous first foamed layer (11, 12, 13, 14, 15, 16, 17, 18) made of thermoplastic foamed material, with an upper side (25, 26) and an under side (34, 35, 36), wherein a first pulling body (41, 42, 43, 44, 46, 47, 48) is arranged on the under side (34, 35, 36) and comprises a first textile layer and a pulling body under side (54, 56, 58), and wherein no layer is arranged between the continuous foamed first layer (11, 12, 13, 14, 15, 16, 17, 18) and the first pulling body (41, 42, 43, 44, 46, 47, 48), which hinders a local shearing displacement of the first pulling body (41, 42, 43, 44, 46, 47, 48) parallel to the under side (34, 35, 36) or stiffens said pulling body.
