材料学翻译（英译汉）
2.1. Materials
The titania pigments used in this study and their associated properties were all experimental grades prepared in the laboratories of Millenium Inorganic Chemicals, Grimsby, UK and are listed by alphabetical codes in Table 1. Experimental samples of titania prepared via the sulphate and chloride routes were milled for different periods of time in order to examine the influence of particle size on durability and spectroscopic properties as were various untreated and surface treated grades of pigments.The phenolic antioxidant, Irganox 1010 (pentaerythrityl tetrabis(3,5ditertbutyl4hydroxyphenyl)propan1oate) and hindered piperidine light stabiliser, Tinuvin 770 (bis(2,2,6,6tetramethylpiperidinyl sebacate) was obtained from Ciba Specialty Chemicals, Manchester,UK while the unstabilised polyethylene (in powder form) was supplied by a European manufacturer with a number average molar mass of 156,000. A metallocene catalyst was used in the production of this material. The polyethylene formulations were processed using a
Brabender Plasticorder (Duisburg, Germany) fitted with W50E chamber and cam blades @ 170 C for 7 min each and then compression moulded into film (100–200
mm thickness) for 1 min.
2.2. Paint formulations
The alkyd paint formulation used is based on an 18% PVC air drying long oil alkyd based on commercial Sobral P470 supplied by the Scott Bader Company Ltd.,Wellingborough, Northants, UK. The paint drier is a commercial Manosec CD33 supplied by Rhone Poulenc
Chemicals, Manchester, UK while the methyl ethyl ketoxime was supplied by Banner [Samuel]
