The present invention relates to gas evaporator devices (1) and methods for operating them. By virtue of the improvements according to the invention, the service life of conventional gas evaporator devices can be significantly improved, such that the maintenance and material outlay and hence the costs of the coating method are reduced. This is achieved by virtue of the fact that a shielding element (5) impermeable at least to passage of the material is provided at least between the mixture of gas and material flowing in the section (4), in which material to be evaporated is guided in a gas flow and is heated by the heating element (2), and the heating element (2).

摘要:
Liquid coating solutions impart hydrophobicity to substrate surfaces (e.g., glass) and include a silane, preferably octadecyltrichlorosilane (OTS), dissolved in a liquid paraffinic solvent. Preferred liquid paraffinic solvents are normal (straight chain) liquid parrafins having between 10 to 20 carbon atoms per molecule exhibiting flash points (ASTM D93) of between about 70° C. to about 160° C., and initial boiling points (ASTM D86) of between about 185° C. to about 300° C. The OTS will be present in the hydrophobic solutions in amounts sufficient to form a hydrophobic coating on surfaces of substrates on which the solutions are applied, and most preferably will be present in amounts ranging between about 0.25 to about 2.5 molar. Applying a coating of the solution onto a substrate surface will allow the OTS for form a self-assembled monolayer thereon imparting hydrophobicity to the substrate as determined by a high contact angle of at least about 100°.

There is provided a technique for interleaving glass sheets (which may or may not be provided with low-E coatings thereon) during shipment, transport, storage, and/or the like. In certain example embodiments, the glass sheet interleaving material includes a mixture of: polymer inclusive beads or particles of material such as polymethymethacrylate, and a stearate such as an acid stearate or the metal salt of an acid stearate. The interleaving material mixture may be applied to the glass sheets in any suitable manner.
