Dip bath

TLC plate which is wetted with reagent solution when it leaves the dipping bath before laying it on the hotplate, laboratory bench or scanning stage. 

Dipping method for adhesive coating of the metal discs is the best method for moulded rubber products manufacture while the quality control required is frequent checks on viscosity and solid content of the dipping bath. The later will be maintained by slow and constant agitation both vertically and horizontally in the bath. 

Aliphatic hydrocarbons or perchloroethylene are used for the chemical cleaning of textiles. Resins are often added to the dipping baths to hydrophobize the textiles [14.259]. 

Hot-dip aluminizing consists essentially in the surface pretreatment of the steel followed by immersion in a bath of molten aluminum at 705°C-760°C. There are many patents covering surface pretreatment, for not only must the steel be clean, but it must also be preheated and protected from oxidation before immersion in the hot-dipping bath [118], Successful techniques have used copper wash coatings, controlled reduction, and both molten and gaseous fluxing. 

The capacity of metal, glass, or salt baths for continuous operation differs from that of batch-type (dipping) baths because the coefficient of heat transfer is increased by the movement through the bath of the strip or pieces being coated. That movement also enhances temperature uniformity as well as finished product quality. 

Chemical polishing in bright dip baths is related to acid cleaning. It has been developed primarily for aluminium and is cheaper than mechanical or electropolishing (see below). A typical bright dip bath operating at 95°C has the following composition ...

The dry reinforcement is then allowed to pass through this unit to get impregnated by the resin. There are three types of impregnation systems currently used (1) dip bath, (2) straight through bath and (3) resin injection system (Owens Coming, 2003). 

The solid PEGs, too, are good heat transfer media in their molten state. The viscosity is frequently the determining factor in choosing one particular grade low-viscosity dip baths prevent high carryover losses.

The OP dips (and sprays) have long been used for the treatment and attempted eradication of sheep scab. This disease has major animal welfare implications for the sheep and major economic implications for the farmer. The disease can result in loss of the fleece and severe lesions on the animal that are then open to secondary infection by bacteria and parasites. The disease is caused by the sheep scab mite Psoroptes ovis. Organophosphorus-based dips have long been used for the treatment and attempted eradication of the disease. In this process, animals are submerged in the dip bath fluid so that the entire body surface, including the head, is submerged. They then exit the bath and in... 

Printing of binders Binders are applied using perforated calender rollers via a dipping bath. Consolidation is achieved by the chemical reaction of the binder.

The technique of dispersion coating depends on the purpose of the final article. Where very thin coatings are required or only impregnation of a fabric is needed, low viscosity dip baths are used. For thicker coats or where only a one-sided coating is desired, a variety of spreading techniques are used. Regardless of technique, it is essential to remove all solvent from the coated layer before curing commences to prevent porosity in the final vulcanisate.
