Sintesis karbonat organik untuk pembuatan toulen bikarbonat

" TDI (toluene diiocyanate) serves as a hardener in the manufacture of composite propellant. The manufacture of TDI steps are long enough, one of which is the formation of toluene dicarbamate which will be decomposed to form TDI. To make toluene dicarbamate own needs an organic carbonate compound as the reactan. Then, the study of organic carbonates need to be done to choose the suitable one of the process and easy in manufacture and availability of ... "

Korelasi kadar nitrogen dalalm nitroselulosa

" One of military rocket propellant main components is nitrocellulose. Nitrocellulose is made by nitration reaction with nitrating agent mixture of nitric acid and sulphuric. The most important Nitrocellulose quality is nitrogen content. Determination of nitrogen content by using of instrumentation is avoided because of explosive material. Therefore we looked for the appropriate method. We conducted a study of nitrogen content related with the properties. From these properties We can determine the nitrogen content. From some ... "

Panjang penyaluran carbon fibre pada perkuat struktur balon beton di daerah Tumpuan = Carbon fibre development length on concrete beam structure reinforcement in a support area

" ABSTRAK
Material Carbon Fibre Reinforced Polymer (CFRP) merupakan bahan non-logam yang terbuat dari carbon fibre (serat karbon) dan mempunyai kekuatan tarik 2800 MPa sehingga apabila digunakan secara komposit pada struktur beton akan berperan dalam memberikan kekuatan tarik yang besar. Pada tesis ini akan diuraikan penelitian panjang penyaluran carbon fibre pada perkuatan struktur balok beton bertulang di daerah tumpuan, dalam hal ini perbaikan (Sikadur 31 & Sikadur 752) dan perkuatan (Sika Carbodur Plates & Sikadur 30) untuk ...
