In a case of disposing a jet dispersing device for jetting, spraying and mixing a main agent and a curing agent by passing them through fine nozzle holes in a coating material flow channel in an in-line arrangement, it is adapted such that a cleaning fluid can be caused to flow about at a flow rate capable of cleaning the coating material flow channel rapidly and reliably. A jet dispersing device (1) in which a partition wall (4) for partitioning a high pressure region (3H) having a flow inlet (2in) and a low pressure region (3L) having a flow outlet (2out) is formed with nozzle holes (5, - - -) for jetting out a liquid from the high pressure region (3H) to the low pressure region (3L) and dispersing the same as fine particles, wherein a cleaning fluid communication port (6) of a larger opening area compared with that of the nozzle holes (5, - - -) is formed to the partition wall 4, and the valve mechanism (V) for opening and closing the communication port (6) is provided,

A conjugated diene sulfonation product represented by the formula (I): ##STR1## wherein R.sup.1 to R.sup.6, which may be the same or different, represent hydrogen atoms, alkyl groups having 1 to 8 carbon atoms, aryl groups having 6 to 20 carbon atoms or --SO.sub.3 X groups (X represents a hydrogen atom, a metal atom, an ammonium group or a quaternary ammonium group), at least one of said R.sup.1 to R.sup.6 being the --SO.sub.3 X group, a polymer of the conjugated diene sulfonation product or a copolymer of the conjugated diene sulfonation product with a monomer copolymerizable therewith. The sulfonation product, the polymer and the copolymer are useful as a dispersing agent for preparing a solid fuel dispersion, a cement dispersion, a dye and/or pigment dispersion or a metal oxide dispersion or as a water-treating agent, a fiber-treating agent, a plating bath additive and an excavation-muddy water-viscosity-adjusting agent.

A small-sized and inexpensive coating material feeding apparatus capable of feeding even a coating material comprising less miscible main agent and curing agent as in an aqueous two component mixed coating material, while uniformly mixing them, to a coating machine or a coating material tank under extremely simple control, the apparatus comprising a measuring unit having a measuring cylinder for delivering the coating material ingredients each by an amount in accordance with the mixing ratio individually and simultaneously to the coating material tank, a storage unit having a transfer cylinder for storing the coating material prepared by mixing each of the coating material ingredients previously and then delivering the same to the coating machine or the coating material tank, and a valve unit formed with a switching valve for conducting channel switching, in which the coating material ingredients delivered from the measuring cylinder are pre-mixed in the channel stirring pre-mixer and a coating material delivered from the transfer cylinder is uniformly diffused and mixed in a jetting diffusion mixer.
摘要:
A surface decorated article in which a surface is entirely or partially decorated with a coating of a first and second glitter paints each using a flaky glitter material as a pigment, wherein first paint particles at a low viscosity with a relatively high solvent dilution ratio formed by coarsely particulating a glitter paint and second paint particles at a high viscosity with a relatively low solvent dilution ratio formed by coarsely particulating a glitter paint are coated in a state mixed with each other, to form the coating comprising areas in which the first paint particles are dried to solidify and areas in which the second paint particles are dried to solidify are mixed together in a spotwise pattern. The surface of articles can be provided with colors or textures exhibiting unique and high quality feelings.

摘要:
A process for preventing formation of scale which comprises adding, into a water system in which ozone is used for disinfection, a polymeric scale inhibitor having a high molecular weight which gives an average molecular weight within an optimum range for preventing formation of scale after the polymeric scale inhibitor is decomposed with ozone. In accordance with the process, the polymeric scale inhibitor having an average molecular weight within the optimum range for preventing formation of scale is present in the water system in which ozone is used for disinfection and formation of scale is effectively prevented.
摘要:
A water-treating agent comprising a ternary copolymer of conjugated dienesulfonic acid/(meth)acrylic acid/2-hydroxyethyl (meth)acrylate, or a ternary copolymer of conjugated dienesulfonic acid/(meth)acrylic acid/(meth)acrylamido-2-methylalkanesulfonic acid ternary copolymer, is effective against scaling and fouling in water systems and a method for treating water with the water-treating agent. When combined with a corrosion inhibitor, the water-treating agent exhibits an excellent anti corrosion effect.
