Blending Nomex® with cotton improves its affordability and serviceability. Because cotton is a highly flammable fiber, Nomex®/cotton blend fabrics containing more than 20% cotton require flame-retardant treatment. In this research, combination of a hydroxyl functional organophosphorus oligmer (HFPO) and 1,2,3,4-butanetetracarboxylic acid (BTCA) was used for flame retardant finishing of the 65/3...
A fluorine-free and multifunctional superhydrophobic coating (r-MSC) was prepared by the one-step spraying method. The had low-adhesion properties with water contact angle of 161.5° ± 1° sliding 3.2° 0.5°. It could be while maintaining surface characteristics on any substrates. owed outstanding mechanical durability chemical stability. Moreover, also possessed ability self-cleaning, anti-foulin...
This paper presents an analysis of the use of red phosphorus as a flame retardant material in encapsulated microcircuits and discusses the reliability risks. Chemical reactions, which can arise when red phosphorus is exposed to ambient humidity to form highly mobile ions and oxygen-containing phosphorus acids, are presented. These ions and acids can induce electro-chemical migration, causing sh...
The current aim of our research work is to isolate bio-polymer from fresh rhizomes of Zingiber officinale & to evaluate its retardibility by formulating microdwarfs containing nimesulide as a model drug. The bio-material was isolated by a simplified method. Six different bio-micro dwarf formulations were prepared using isolated bio-material as a retardant. The formulated microcapsules were eval...
تغییر در ساختار پروتئین های بدن منجر به تولید آنتی بادی علیه آنها می شود. احتمالا ایجاد پلی مرفیسم در ژن پراکسیداز تیروئیدی (tpo) و تغییر ساختار آن باعث تولید آنتی بادی ضد پراکسیداز تیروئیدی می شود. اختلال درآنزیمtpo می تواند یکی از دلایل اصلی بروز بیماری کم کاری تیروئید باشد که شیوع و گسترش این بیماری، ما را بر آن داشت که در این مطالعه به بررسی ارتباط پلی مرفیسم a1936/g اگزون11و t2229/c اگزون1...
The flame-retardant thermoplastic polyurethane (TPU) with remarkable smoke suppression, anti-dripping and mechanical properties has been still a big conundrum in the field of fire safety science. In this article, an urethane-based phosphonate ester (UPE) flame retardant additive was successfully synthesized incorporated into TPU. safety, performance mechanisms TPU/UPE composites were lucubrated...
Flame retardants, such as inorganic fillers or halogenated resins, are incorporated into composites either as additives or reactive materials. In order to improve processability and mechanical properties, as well as reduce smoke toxicity, a method is being developed to introduce highly effective, inexpensive flame retardant materials into thermoset resins. Superabsorbent polymers (SAP) can be l...
مقدمه : سقط شایع ترین عارضه بارداری بوده و در ? 15 حاملگی ها رخ می دهد . اختلالات ایمنولوژیک یکی از علل شایع سقط می باشد که خود شامل فاکتورهای آلوایمیون و اتوایمیون می باشد . با توجه به نقش آنتی بادی ها ضد تیروئیدی از جمله anti-tpo به عنوان یک فاکتور اتوایمیون در ایجاد سقط های خودبه خودی ومکرر ، در این مطالعه به بررسی ارتباط بین این دو می پردازیم . اهداف : هدف کلی : بررسی ارتباط بین سطح anti-...
A series of treated and untreated laminated Douglas fir beams and plywood panels were subjected to static and dynamic loads to study the effects of pressureimpregnation with fire-retardant chemicals on the mechanical properties of wood and to extend the existing knowledge cf the dynamic properties of wood. Results from the beam tests indicate that designs should be based on use under wet condit...
Different kinds of additive and reactive flame retardants containing phosphorus are increasingly successful as halogen-free alternatives for various polymeric materials and applications. Phosphorus can act in the condensed phase by enhancing charring, yielding intumescence, or through inorganic glass formation; and in the gas phase through flame inhibition. Occurrence and efficiency depend, not...
