Abstract:
Provided herein are compositions that include an aqueous-based insulating fluid that comprises an aqueous base fluid, a water-miscible organic liquid, and a synthetic polymer. In another embodiment, provided herein is a method of forming an aqueous-based insulating fluid comprising: mixing an aqueous base fluid and a water-miscible organic liquid to form a mixture; adding at least one synthetic polymer to the mixture; allowing the polymer to hydrate; optionally adding a crosslinking agent to the mixture comprising the synthetic polymer to crosslink the synthetic polymer; placing the mixture comprising the synthetic polymer in a chosen location; allowing the mixture comprising the synthetic polymer to activate to form a gel therein.
Abstract:
본 발명은 상어표피를 모방한 저마찰 부재 및 그의 제조방법에 관한 것으로, 판상형 입자 표면에 구형의 입자가 부착되어 이루어진 복합입자를 겹겹이 적층시킴으로써 리블렛이 형성된 상어 표피와 유사한 구조체를 구현하고 이를 통해 우수한 저마찰 특성을 갖도록 한 것이다. 이러한 본 발명은, 기판과; 상기 기판 표면에 비늘 형태로 겹겹이 적층된 판 상형의 입자와; 상기 판상형의 입자보다 작은 크기를 갖고 상기 판상형의 입자 표면에 대하여 다수 코팅된 구형의 금속 윤활입자로 이루어져, 상기 금속 윤활입자가 상기 기판과 판상형의 입자 간, 판상형의 입자와 판상형의 입자 간을 연결하는 브릿지 형태로 배치된 것을 특징으로 한다.

Abstract:
A self-lubricating composite material is disclosed. The self-lubricating composite material can include discontinuous polymer fiber segments dispersed within a woven matrix of semi-continuous thermoplastic fiber. The woven matrix can be embedded within a thermosetting resin. Also disclosed are methods of manufacturing the self-lubricating composite material.
Abstract:
La présente invention concerne un procédé de lubrification d'une vessie en caoutchouc dilatable utile lors d'une vulcanisation d'un pneu cru au sein d'une presse métallique caractérisé en ce que des compositions sous forme d'émulsions d'huiles silicones sont appliquées sur la surface interne des pneumatiques crus et/ou à la surface externe des vessies de vulcanisation pour en faciliter le moulage-démoulage lors de la fabrication des dits-pneumatiques.
