摘要:
Method for making light-weight gypsum board with enhanced compressive strength by addition of dispersants. Wallboards made by use of a gypsum-based composition comprising a ketone resin as dispersant and a foaming agent.
摘要:
The invention relates to methods for treating ceramic surfaces to decrease their wettability by aqueous solutions. One method involves polishing the ceramic surface until wettability is decreased, and a second method involves a silane heat treatment. Both methods can be used to produce ceramic supports for IEF and electrophoresis gels, as well as microarray plates.
摘要:
A method for increasing the drying rate of set plaster by adding fatty alcohol sulfate to the slurry of calcium sulfate hemihydrate from which the plaster is made.
摘要:
A method of curing concrete beginning with the acquisition of seedless hydro mulch material and incorporating the material into a material spraying device, mixing the material with water in the spraying device and spraying the material and water onto the surface of curing concrete. The spraying device includes a spray nozzle and pressurized air is introduced into the spray nozzle prior to the spraying of the material and water onto the curing concrete. The pressurized air may be provided to the spray nozzle at an air pressure of equal to or greater than 35 psi and less than or equal to 75 psi.
