摘要:
A method of applying a refractory castable material to the surface of a structure comprising the steps of thoroughly mixing a refractory castable material comprised primarily of aggregate and a cementitious binder; conveying the refractory material under pressure through a delivery hose to a dispensing nozzle; and adding hydrated lime to the refractory castable material prior to application by the nozzle.
摘要:
A process for the improvement of adhesion between fluoropolymers or fluorocopolymers and inorganic compounds as well as composites made by this process are disclosed. The inorganic compound is coated with an adhesion promoter. Contacting the adhesion-promoted inorganic compound with the fluoropolymer or fluorocopolymer and heating develops the adhesive bond.
摘要:
The present disclosure provides methods of making organosiloxane polymer compositions from hydrosilylation curable compositions comprising at least the components (a) and (b) and at least one of components (c) and (d): (a) an organosiloxane resin material comprising aliphatic unsaturation; and (b) an organosiloxane crosslinker comprising multiple silicon atom-bonded hydrogen atoms (e.g., an "SiH siloxane"); in combination with at least one of (c) at least one organosiloxane comprising at least two silicon atom-bonded hydrogen atoms; and (d) at least one organosiloxane comprising at least two silicon atom-bonded hydrocarbyl groups comprising aliphatic unsaturation (e.g., a "di-vinyl functional siloxane"). Such hydrosilylation curable compositions have, in some instances, significantly faster cure speed, relative to their condensation curable counterparts. A faster cure speed can be important for encapsulating electronic devices, such as light-emitting diode (LED) chip devices, including devices having tall structures.

摘要:
Honeycomb structure (1) comprising, arranged so that multiple cells (5) as a flow channel for exhaust gas are provided between two end faces through unified bonding of honeycomb segments (2) having part of the whole configuration by means of bonding material (9) and through working of the outer circumference of the bonded segments into given configuration, numerous first-pore having internal cell walls (6), numerous second-pore having outer circumferential walls (8) disposed so as to surround the internal cell walls (6) and numerous third-pore having internal cell walls (outer circumferential internal cell walls) (11) abutted to an outer circumferential wrought surface becoming the outermost circumference by working of the outer circumferential part, wherein a filling material containing not only particles with a diameter allowing the same to enter the interior of the second pores but also a binder capable of binding of particle and interior of the second pores of the outer circumferential walls (8) and/or particle-to-particle is disposed in the interior of the second pores of the outer circumferential walls (8).
摘要:
Organic polymer particles are provided in a cement composition that is used to apply a skin to a ceramic honeycomb, or to bond the ceramic honeycomb to another honeycomb or another material. The presence of the organic polymer particles reduces the penetration of the cement composition through porous walls of the honeycomb. In this way, less blocking of the honeycomb cells is seen, and the reduction in thermal shock performance that is often seen when cement compositions are applied to ceramic honeycombs is reduced.
