摘要:
The present disclosure relates to the field of storage bags, and discloses a fireproof, explosion-proof and heat-insulating storage bag, including a storage bag body, where the storage bag body is composed of a first fireproof fabric, a heat insulation material, an auxiliary molding material, and a second fireproof fabric. In the present disclosure, different specifications of models are formed by a fireproof and explosion-proof material, the heat insulation material and an auxiliary molding material; a plurality of materials are integrated to achieve fireproof, explosion-proof and heat-insulating functions, so that it is ensured that the product cannot be damaged within a certain period of time when placed on a fire source, and no spontaneous combustion occurs inside the storage bag. The fire source leakage is prevented, the fire source is prevented in the storage bag, and no fire is caused, thereby achieving the fireproof, explosion-proof and heat-insulating functions.
摘要:
A bonding composition for incombustible fibrous materials comprising (a) a water-soluble polymer containing hydrazide groups or its adduct with a water-soluble alkaline earth metal salt of an inorganic acid and (b) a heavy metal ion capable of forming chelate with the water-soluble polymer or its adduct. The bonding composition is employed as bonding agents to prepare incombustible sheet materials from incombustible fibrous materials by adding the components (a) and (b) to an aqueous dispersion of the fibrous materials and forming sheets or by forming wet or dry sheets containing the component (b) and then making the component (a) contain in the sheets. The bonding composition has excellent bonding effect and the polymer itself becomes incombustible, so incombustible sheet materials having excellent strength can be economically obtained.

NOVEL COMPOSITION FRICTION ELEMENTS ARE DISCLOSED HAVING THE ABILITY TO QUICKLY SEAT-IN AND CONFORM TO THE CONTOUR OF AN IRREGULAR BRAKING SURFACE WITHOUT FADING OR SACRIFICING BRAKING LIFE. THE NOVEL ELEMENTS COMPRISE A BASE OF CONVENTIONAL FRICTION MATERIAL HAVING A FRICTIONAL CONTACTING SURFACE TREATED WITH A SECOND FRICTION MATERIAL HAVING A HIGHER COEFFICIENT OF FRICTION AND A LOWER RESISTANCE TO WEAR THAN THE BASE MATERIAL.

摘要:
Reducing or absorbing the noise transmission of a component such as a metal sheet, metal pressing or metal casting which is prone to vibration by applying directly or indirectly to at least part of the surface thereof a layer of one or more sheets of asbestos fibre-filled bitumen composition, in laminate form, to an overall thickness of at least 1.5 mm, the weight rates of asbestos to bitumen being in the range 40:60 to 60:
摘要:
The invention comprises treating asbestos cloth and other asbestos products to reduce the dust emitted by them during handling and use. This is done by distributing a small amount of polymeric particles throughout the product to bond the fibers to one another, while leaving the properties except the dustiness essentially unchanged. The preferred method consists in impregnating asbestos cloth with an aqueous emulsion or suspension of the polymeric material and removing the water.
摘要:
A fire-resistant polymeric membrane includes a polymer layer such as PVC, TPO, or EPDM affixed to a carbon fiber composite. The carbon fiber composite includes one or two layers of non-woven carbon fibers and at least one of an inert fiber mat or a metal foil layer, wherein the metal foil layer has a melting temperature of at least about 660° C. The present invention also provides an underlayment, wherein the underlayment is formed from one or more fibrous carbon layers affixed to at least one of an inert fiber mat or a metal foil having a melting temperature greater than 660° C.
摘要:
Sheet vinyl covering material having a moisture permeable backing layer of material such as asbestos felt which is dimensionally stable under varying moisture conditions and resistant to degradation from water. The backing layer is sealed on one side with a layer of vinyl halide-vinylidene halide copolymer which is overlaid with a layer of open cellular foamed resinous material. The sheet vinyl laminate also has a resinous wear layer overlying the foamed layer.
