項目名稱：采購4噸XC生物聚合物
招標內容：Supply of 4 MT of XC Polymer Premium
產品描述和用途：
1. Premium quality highly refined and clarified Xanthan Bio-polymer to be used in workover and completion applications and gravel packing.
2. The product should be a high molecular weight biopolymer produced by the action of microorganism Xanthonomous Camprestis on a high purity carbohydrate Xanthan gum. The material should be free from all kinds of dead bacteria and should give clear water like solution without any turbidity.
技術參數：
1. Physical Properties:
The material, as received, should be a free flowing off white powder.
2. Particle Size:
a) Passing through 20 mesh, % by mass: 98% minimum
b) Passing through 40 mesh, % by mass: 95% minimum
3. Transmittance: 2.85 gm/litre (1 lb/bbl) of the material in 3% (w/v) KCl solution should give minimum 90% transmittance at 600 nm, while 3% (w/v) KCl solution is used as 100% transmittance standard.
4. pH of 1% (w/v) solution in distilled water: 7.0 – 8.0.
5. Loss on Drying, % by mass: Loss on drying at 110 Deg. C for 3 hours: 15 maximum.
6. Viscosity: Absolute viscosity at 0.1 Sec-1 and 25 Deg.C for 1% (w/v) solution of the sample in tap water, stirred for 30 min. in Hamilton Beach Mixer should not be less than 80,000 cP.
7. Salt Tolerance: Loading 1% (w/v) of the material with KCl up to saturation should not deteriorate its viscosity.
8. Temperature Stability: Heating 1% (w/v) solution of the product in tap water or in saturated KCl at 110 Deg. C for 16 hours should not deteriorate its viscosity.
