Fabrication of Twin Panel Metal Door

ABSTRACTPrivacy and security are major essential human needs in various houses, offices etc. ability to afford quality door and high long life span at an affordable price to an average Nigerian has been a problem. This project is aimed at fabrication of a double panel door which is capable of giving maximum security to life and properties. The locally available material (mild steel) of different shapes, sizes and forms was used with available indigenous technology without compromising t...

Use Of Local Clays For The Production Of Porcelain Pin Insulators

ABSTRACT The use of local clays for the production of porcelain pin insulators was investigated. Clays from Awo-omama, Ibere and Nsu were used for the study. Test samples were made by varying the compositions of feldspar and quartz needed to form a mouldable plastic body with each clay. The following properties were determined: electrical resistivity, apparent porosity, water absorption, bulk density, linear shrinkage as well as crystalline phases produced after firing. This character...

The Effect Of Particle Size And Particle Size Distribution On The Modulus Of Rupture Of Some Nigerian Clays

ABSTRACT The effects of particle size and particle size distributions of three clay samples, on their modulus of rupture were studied. The three clay samples were collected from natural clay deposits at Nsu; OhiyaUmuahia; and Awo-Omamma all in south eastern Nigeria. The particle size analysis of the clay samples was done by laser diffraction in wet suspension mode and the results disclosed that Awo-Omamma clay has greater proportion of the larger sized particles, (21µm - 25µm) and (25...

Study Of The Properties Of Some Local Clays For The Production Of Floor Tiles

ABSTRACT The suitability of some clay deposits in South Eastern Nigeria (Unwana, Ekebedi, Okigwe and Nsu) as materials for the production of floor tiles was investigated. The clay samples were analyzed using wet classical method to determine their chemical composition. Floor tile test specimens were produced using standard method. The test specimens were tested for physical properties such as compressive strength and porosity at 10500 C and 11500 C temperature levels. The chemical a...

Inhibition Of The Corrosion Of Mild Steel In Acidic Environment Using Azadirachta Indica (Neem) Leaf Extract As Inhibitor

ABSTRACT The inhibition of corrosion of mild steel by Azadirachta indica leaf extract in acidic environments of HCl and HNO3 from pH1 to pH6 has been investigated using the weight loss technique. The Azadirachta indica leaf extract is the inhibitor and the mild steel used was in the form of coupons. The investigations were carried out at ambient temperature. The optimum concentration of the extract used for the experimentation was obtained by soaking 200g of ground fresh Azadirachta in...

Factors Affecting The Colour Yield Of An Acid Dye On Nylon Fabric

ABSTRACT The factors that affect the colour yield of an acid dye on nylon fabric were investigated at a constant temperature of 500C, usingC.I. Acid Yellow 23,with citric acid and sodium chloride as auxiliaries. It was observed from the absorbance results that the colour yield of C.I. Acid Yellow 23 improved with increase in time of dyeing, while the absence or increase beyond 1% (acid) and 5% (salt) reduced the colour yield of the acid dye on the nylon fabric. Also, at a constant dyei...

Effect Of Cooling Rate And Modification On The Microstructure And Tensile Properties Of Al-Si-Mg Alloy

ABSTRACT The effect of cooling rate and modification on the microstructure and tensile properties of Al-Si-Mg alloys was carried out. Castings were produced using a stepped pattern that has different section thicknesses. Sand casting technique was used. A thermocouple inserted into the mould cavity recorded the cooling rates for the different sections. The Al5.43%Si3.83%Mg which was melted in the crucible furnace was modified with sodium (Na) and strontium (Sr) in separate cases. The m...

Bacteria Corrosion Of Mild And Medium Carbon Steels

ABSTRACT Investigations were carried out to determine the corrosion effect of sulphur-reducing bacteria on mild and medium carbon steels. Specimens were exposed to anaerobic, aerobic and distilled water environments. The corrosion rates were evaluated at intervals of seven days using weight loss and electro-chemical methods for a period of forty two days. The specimens were also subjected to visual examination and the result indicated uniform corrosion in all the environments. In all ...
