This disclosure relates to a substrate treating method and a treatment liquid. The substrate treating method includes a treatment liquid supplying step, a solidified film forming step, and a sublimation step. In the treatment liquid supplying step, a treatment liquid is supplied to a substrate. The treatment liquid contains a sublimable substance, a solvent, and a surfactant. In the solidified film forming step, the solvent and the surfactant evaporate from the treatment liquid on the substrate. In the solidified film forming step, a solidified film containing the sublimable substance is formed on the substrate. In the sublimation step, the solidified film sublimates. The surfactant has an octanol-water partition coefficient LOGPow of ?1 or more and 1 or less. Vapor pressure Pc of the surfactant at room temperature is 0.9 times or more and 3 times or less vapor pressure Pb of the solvent at room temperature.

Methods and systems for cleaning, coating and sealing leaks in existing nonmetal pipes, in a single operation. A nonmetal piping system can be cleaned in one pass by dry particulates forced and pulled by air throughout the piping system by a generator and a vacuum. Nonmetal pipes with nonmetal fittings or nonmetal pipes with metal fittings or nonmetal pipes with a combination of metal and nonmetal fittings can be protected from wear by water erosion and rupturing, extending the life of pipes made of a nonmetal material selected from at least one of plastics, PVC (polyvinyl chloride), composite materials, or polybutylene. Coatings can be applied to nonmetal pipes having diameters up to approximately 6. Leak sealants of at least approximately 4 mils thick can cover insides of nonmetal pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the nonmetal pipes during applications. Piping systems can be returned to service within approximately 96 hours.

It is provided in a liquid application system for applying liquid to a material cake transported on a conveyor device having a liquid application device, that the conveyor device comprises a porous section on which the material cake lies or which the material cake contacts and which is permeable for a liquid to be applied, that the liquid application device comprises an application device via which the liquid to be applied can be applied to the side of the porous section of the conveyor device facing away from the material cake, and that the liquid application device comprises an overpressure chamber having a first overpressure relative to the environment by which the porous section of the conveyor device passes, wherein the applied liquid can be transported via the first overpressure through the porous section of the conveyor device or held via the first overpressure to the porous section.

A method of coating a substrate with a white molecular coating. A colloidal based primer is prepared having on a mass basis between 30-40% suspensions of fine-sized spherical particles of nonporous silica dispersed in liquid phase. The primer is applied to the substrate and allowed to dry. A molecular adsorber coating is prepared by treating a zeolite with a colloidal silica binder thereby providing a treated pigment having a mass ratio of the colloidal silica to the zeolite is in a range of 2.0 to 2.6, then processing the treated pigment into a powder thereby facilitating sprayability and then mixing said treated zeolite with a colloidal solution containing silica. The coating is then sprayed onto the primer and allowed to dry. The resultant coating provides adequate bond stability and strength necessary for flight applications within an environment for vacuum of space applications.
