Flame resistance

This study investigated the effect of graphene content on intumescent coating properties. Intumescent coatings contained Plextol R4152 as a binder, APP-PER-MEL as a flame retardant additive system, TiO2, Al(OH)3 as fillers, and other additive. The fire resistance test and furnace test were conducted. TGA, DSC, and SEM were used to assess the coating and char layers. The water resistance and mechanical properties of the coatings were examined.

While it is recognised that knitted fabrics may have their place in firefighting PPC, especially for undergarments, from the point of view of fire performance, strength and presentation, woven fabric constructions appear to be more suitable for work wear applications. Hence, this study is concerned with developing and testing a range of functional, woven Station Wear fabrics designed to enhance flame protection, durability and thermo-physiological comfort properties. In trying to improve all three aspects, a compromise in the properties of fabrics developed would be very likely.

SiO2 and TiO2 sols were successfully synthesized by using sodium silicate and titanium chloride as Si and Ti sources. SiO2-TiO2 sol coated polyester/cotton fabric was fabricated by deepcoating method and using SiO2 , TiO2 sols as coating materials. SiO2 -TiO2 coated fabric were characterized by XRD, FTIR, TGA, SEM and EDX. From SEM image, it showed the SiO2, TiO2 particles of 20-30 nm which well deposited on fabric surface. TGA result revealed the significant improvement of thermal resistance and stability of SiO2-TiO2 coated fabric as compared to those of uncoated fabric.

In this study, we synthesized silica sol by ion exchange from sodium silicate. Silica sol solution is used for coating the surface of cotton fabrics [21, 22]. Effect of nanosilica content (through number of coating times) on fire resistance (UL-94, LOI) and mechanical properties of the materials are investigated and evaluated.

The study included 150 patients admitted in burns unit at Osmania General Hospital, Hyderabad over a period of six months from March 2015 to August 2015. The wound swabs collected were sent to Microbiology lab for Grams stain, Culture and Antimicrobial susceptibility. Majority of the cases were in the age group 20- 30 yrs. Females outnumbered males. Burns due to flames were the most common cause of the wound. Among 150 samples, 143 were culture positive of which, Staphylococcus aureus (S. aureus) was the predominant isolate followed by Klebsiella.

With respect to the sampling of tomato it occurred at the beginning, on the highest peak and at the end of the production stage of tomato. For each sampling unit a zigzag path by the crop was followed, harvesting a tomato every three places along the zig-zag, and then based on a quartering system, obtaining a sample of 1 kg per plot.

Basic knowledge of cement a), Chemical composition of cement and hydration of clinker compounds Of the above figures, Alite has the most first hydrate reaction, therefore Alite contributes considerably to short term strength and the hydrate reaction completely finishes for a few months. While the hydrate reaction speed of belite is lower. As the result, the development of the short term strength is low, but it effects the long term strength. Alite reaction with water is the most activity, and interstitial material is also high reaction with water.(see figure 1)...
