摘要:

AbstractBased on statistical data and Delphi input, a logic has been worked out which is capable of offering quantitative support for decisions concerning the equivalence of various fire safety alternatives. Examples of the use of the logic are presented and some conclusions drawn as to the relative merits of various fire safety measures.

摘要:

AbstractThis paper examines the effect of different thermal regimes on the production of smoke from a variety of injection‐moulded polypropylene samples. The tests were performed in a Stanton Redcroft BS 6401 smoke chamber. The results indicate that, of the thermal regimes examined, the radiant heat source alone produced the smoke with the greatest optical density, particularly after long exposure times, while the addition of an inorganic salt to the polypropylene produced a reduction in optical density. The different thermal regimes produced different effects depending on the additives used in the preparation of the polypropylene sample

摘要:

AbstractIn view of the current demand for novel, non‐toxic, flame‐ and smoke‐ suppressant systems for synthetic polymers, certain inorganic tin compounds have been evaluated as fire retardants in a series of commercial brominated polyester resin formulations. The results obtained clearly show that zinc hydroxystannate (ZnSn(OH)6) and zinc stannate (ZnSnO3) impart beneficial properties to the polyesters in terms of flame retardancy and smoke/carbon monoxide suppression, and the improvements in performance are, in general, superior to those exhibited by tin (IV) oxide or antimony (III) oxide. The surface area and degree of dispersion of the fire‐retardant additive has been shown to have a marked effect on its efficiency and, in this connection, colloidal tin (IV) oxide is found to exhibit significantly improved flame‐retardant properties compared to powdered SnO2. Simultaneous thermal analyses (TG/DTG/DTA) and related mechanistic experiments have shown that tin additives markedly increase the amount of char formed during combustion, whereas Sb2O3, a vapour‐phase flame retardant, has little effect on char formation. The zinc stannates also appear to exhibit a significant vapour‐phase activity, and this may account for their flame‐retardant superiorit

摘要:

AbstractThe determination of the time of response of industrial temperature sensors both during service and in various environments is of importance. Recent effort has been directed at this problem solution. The present paper is concerned with the determination of the response time using available procedures recently developed. A rig was constructed to test the procedures. The results appear to provide confidence in the use of these procedures.
