摘要:
Thermally formed thermoplastic articles can be protected from stress cracking in the presence of stress cracking promoting compounds by forming a shaped article comprising a thermoplastic and a liquid hydrocarbon oil composition. We have found that the liquid hydrocarbon oil composition prevents the stress cracking promoting materials from interacting with the polymeric structure of the stressed container to prevent or inhibit stress cracking in such materials. The methods and compositions of the invention are particularly useful in preventing stress cracking in polyethylene terephthalate beverage containers during bottling operations during which the bottle is contacted with aqueous and non-aqueous materials such as cleaners and lubricants that can interact with the polyester to cause stress cracking particularly in the container base. A process for lubricating a container, such as a beverage container, or a conveyor for containers, by applying to the container or conveyor, a thin continuous, substantially non-dripping layer of a liquid lubricant. The process provides many advantages compared to the use of a conventional dilute aqueous lubricant.
摘要:
The passage of a container along a conveyor is lubricated by applying to at least a portion of the container-contacting surface of the conveyor or to at least a portion of the conveyor-contacting surface of the container a coating comprising a hydrophilic material wherein the lubricating properties of the coating are enhanced by contact with a polar liquid; polymerizing or otherwise solidifying the coating; and contacting the coating with such polar liquid. If desired, the coating can be applied or polymerized on the conveyor or container while the conveyor line is in motion.
摘要:
The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts and with relatively low or no water content, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
摘要:
A photosensitive composition is prepared containing a polymer of the formula B(X)(Y) wherein B represents an organic backbone, each X independently is an acidic group or salt thereof and each Y independently is a photocurable group and a photoinitiating compound or compounds. Preferably, free-radically polymerizable multi-functional monomer and/or oligomer is added to the photosensitive composition. The photosensitive composition can be coated on a suitable substrate for planographic printing plate applications. Imagewise irradiation causes the light struck regions to photocure, becoming insoluble in aqueous and organic mediums, while the non-light struck regions remain highly soluble/dispersable. Printing plates of this construction do not require processing prior to being run on a press.
摘要:
The present invention is both a method and an apparatus for utilizing a container/connector 10. The container/connector 10 holds a second liquid 110 that is mixed with a first liquid 12a in container 12. Then after mixing to form a use solution, the use solution flows back through the container 10 and out for use by a suitable applicator.
摘要:
A method of cleaning an uncoated surface includes providing a composition having a pH of between about 7 and about 11 and applying the composition to the uncoated surface. The composition includes a fatty acid salt constituting between about 5% and about 40% by weight of the composition, a gloss-enhancing agent constituting between about 0.1% and 20% by weight of the composition, an anti-slip agent constituting between about 0.5% and about 10% by weight of the composition, and water constituting between about 20% and about 94.6% by weight of the composition. The composition can be applied at least three times a week.

摘要:
Floor finishes are stripped or deep scrubbed using a floor stripper/cleaner composition containing sparingly water-soluble floor finish solvent, water, C10 aliphatic acid in an amount sufficient to provide a homogenous aqueous liquid phase during shaking, and sufficient organic amine so that the composition pH is more than 2 and less than 10 and the composition is not corrosive to skin.
摘要:
A method of lubricating conveyor tracks or belts is herein described wherein the lubricant composition contains a polyalkylene glycol polymer, a fatty acid, and an anionic surfactant; also described is a lubricant composition with reduced sensitivity to low pHs. The composition may also comprise additional functional ingredients and be composed of ingredients that can be safely administered to humans and mammals.
摘要:
Floor finishes can be stripped using a substantially nonchlorinated concentrate comprising a floor finish dissolver and an at least partially water-unactivated water thickener. The concentrate is diluted with water at an intended use location to activate the water thickener and noticeably increase within sixty minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.
