  • Patent number: 10246547
    Abstract: The present invention relates to the process for production of a polyol from palm oil and of rigid polyurethane foams prepared from said polyol derived from palm oil. On the one hand, this invention provides a method for obtaining monomeric polyols from palm oil that have hydroxyl number between 50 450 mgKOH/g sample. The polyols of the present application may be obtained by means of a procedure based on the following four mother routes: Route 1: maleinisation of the fatty acids of palm oil; Route 2: glycerolysis of palm oil; Route 3: trancesterification of palm oil; and Route 4: epoxidation of unsaturated carbon-carbon links of palm oil. Additionally, other modalities of the invention permit obtaining polyols from the combination of these mother routes. In other realizations of the invention polyurethanes are prepared from polyols obtained through any of the four routes or by combinations of the same.

  • Publication number: 20130221268
    Abstract: A thermally-conductive paste comprises a carrier, at least one graphene platelet, and a plurality of packing materials. The graphene platelets and the packing materials are dispersed in the carrier. At least a portion of the packing materials contact the surface of the graphene platelet. The graphene platelet has a very high thermal conductivity coefficient and a characteristic 2D structure and thus can provide continuous and long-distance thermal conduction paths for the thermally-conductive paste. Thereby is greatly improved the thermal conduction performance of the thermally-conductive paste.

  • Publication number: 20130119302
    Abstract: An enhancing agent for increasing heat transfer efficiency is disclosed, which is an additive composed of a nano-scale powder and a micro-scale powder that is to be added into a heat-transfer fluid circulating in an heat exchange system or in a coolant circulating in a cooling system for enhancing the heat conductivity of the heat-transfer fluid or the coolant while helping the tank and the fluid passages used in those systems to maintain clean, and eventually enabling those systems to operate with improved heat dissipation effect. By adding the aforesaid enhancing agent into a cooling system of an internal-combustion engine, the heat shock inside the engine that is originated from the fuel burning in the engine can be reduced, resulting that not only the amount of green house gas emission is reduced, but also the chance of engine juddering that is generally originated from poor heat dissipation can be decreased.
