Supply of Carboxyl Methyl Cellulose
Reference: SSG1925P17/05 7/28/2016, Location: Asia
Category: Chemicals
Scope of Work
The company invites bids for the supply of Qty= 110000 KG, Carboxyl Methyl Cellulose - High Viscosity Grade (CMC-HVG)
1. Physical State:
The material as received should be white to creamish coloured free flowing powder and free from lumps and visible extranous impurities.
2. Moisture Content Measured by drying at 105 +/- 2 Deg.C, % by mass, maximum: 10.00
3. Sodium Carboxy Methyl Cellulose content on dry basis, % by mass, minimum. : 55.00
4. Yield of 15 cp Apparent Viscosity Suspension: Prepare a 15 cp apparent viscosity suspension of the sample by stirring in a multimixure for 30 minutes in distilled water and 3.5% salt water (prepared by dissolving 3.5 grms LR grade NaCl in 100 ml distilled water) and calculate the yield of the sample which should be as follows:
a) Yield in distilled water,KL/MT,min.: 200
b) Yield in salt water, KL/MT, min.: 120
5. Packing: The material should be packed in moistureproof multiply (minimum 5 ply) strong paper bags enough to withstand the rigours of transit and storage. Capacity: 25 kg net per bags
Mrking: Eachbag should have clear legible markings as follows:
i) Name of the product
ii) Name of the supplier
iii) Date/Month/Year of manufacture
iv) Supply order number against which the supply is made.
N.B.: Apparent viscosity shall be measured by a Fann VG meter.
