Tracking is the main factor which limits the safe working electric stress of insulation in power system applications. Polymer samples have been tested in laboratory conditions according to ASTM D2303 on accelerated inclined plane tracking test. In this paper, a model based on improved Weibull statistics is proposed for estimating the breakdown time of polymeric insulating materials with borax. ...

The relation of respiratory symptoms, pulmonary function, and abnormalities of chest radiographs to estimated exposures of borax dust has been investigated in a cross sectional study of 629 actively employed borax workers. Ninety three per cent of the eligible workers participated in the study and exposures ranged from 1.1 mg/m3 to 14.6 mg/m3. Symptoms of acute respiratory irritation such as dr...

In Germany the addition of the trace element boron as boric acid or borax to food supplements was not permitted up to now. However, this situation could soon change since the laws in the EU Member States are to be approximated and its addition is permitted in other European countries. If this happens, boron could also go on the market in Germany as an ingredient in food supplements. Against thi...

Borax (Na2B4O7.10H2O) is white crystals, odorless, thermostable substance and a derivative of Boron. used to preserve wood, braze metal, kill cockroaches. Unfortunately, borax misused as food preservative. testing in the laboratory carried out using chemicals equipment that most people do not have. Turmeric can be indicator because it contains curcumin which react with borax. It important educa...

The possibility of using peroxyborates, produced in situ by combining aqueous alkaline hydrogen peroxide and borax, for bleaching and brightness reversion inhibition of thermomechanical pulp was investigated. The peroxyborate material was applied to BTMP paper produced in the laboratory, and from a pilot scale paper making trial. Excellent brightness retention characteristics were exhibited in ...

Adhesives can be used as sealing agents, to eliminate the effect of self-loosening caused by dynamic loads, areas prevent oxidation and corrosion, waterproofing, so on. The aim present study is prepare an adhesive from fresh cassava roots evaluate its physicochemical properties such density, viscosity, pH. are prepared mixing starch, hydrochloric acid, borax. Three samples adhesives were variou...

This paper puts forward a novel non-ionic augmentation system, namely, gelation of native starch in the presence of borax and papermaking fibers. Native starch was blended with high concentration pulp and auxiliary agents. After pasting, the starch gel adhered onto fiber surfaces. However, an excess dosage of agents led to a rigid structure and poor gel strength. Starch became gelatinized and t...
