This invention discloses a kind of 5Y 5.25 / 1 pigmentary combination and its method for preparation of color blocks. The compositions of the said combination are as follows by weight: CSC-C, the base in 995-1005 portions; PY42 with 60% color content, in 15.0-16.0 portions; PBK7 with 9% color content, in 3.0-3.4 portions, PR101 with 65% color content, in 1.44-1.48 portions; PW6 with 65% color content, in 89.98-91.98 portions . The main constituent of the said CSC-C base is acrylic acid copolymer, whose content is 35-45%. The contrast ratio of the main material to the base is 0.20-0.40, the Stomer viscosity is 90-100 KU and the gloss is 5degree-10degreeat an incidence angle of 85degree. The said combination in this invention has characteristics of high weather resisting property and stability, good repeatability of the mixture ratio. All used crude materials and technical processes meet the requirements and standards of low voice and zero voice. The chromatic aberration of the said colorblocks is small compared to the standard values of the theoretic models in the book 'Chinese Color System'. With the high accuracy of the implemented color, the good proficiency of the making technique, the said product has strong use value.

The invention discloses a supercharger impeller blade machining method based on on-machine measuring. The supercharger impeller blade machining method includes: step a, calibrating a triggering-type measuring head; step b, according to a blade three-dimensional theoretic model, setting m measuring workstation coordinate systems, and planning a measuring path; step c, generating a measuring program according to the measuring path, and installing the measuring program in a numerical control system; step d, subjecting blades to rough machining, and mounting the triggering-type measuring head on a spindle of a numerical control machine tool; step e, running the measuring program, driving the triggering-type measuring head to move, and storing measuring point coordinate values; step f, transmitting the measuring point coordinate values of the blades to a computer, performing multi-workstation data aligning on the measuring point coordinate values by the computer, performing comparative calculation with the blade three-dimensional theoretic model to acquire blade machining deformation quantity and deformation rule; step g, calculating blade finish machining reverse compensation allowance, and performing blade finish machining according to the reverse compensation allowance. By the supercharger impeller blade machining method, thermal treatment process is omitted, and the problems of demounting, repairing and repositioning for off-line measuring are solved.

This invention discloses a kind of 7.5P 7.5 / 4 pigmentary combination and its method for preparation of color blocks. The compositions of the said combination are as follows by weight: CSC-B, the base in 995-1005 portions; PR122 with 30% color content, in 1.97-2.01 portions; PV23 with 30% color content, in 0.09 portions, PBK7 with 9% color content, in 0.28-0.30 portion. The main constituent of thesaid CSC-B base is acrylic acid copolymer, whose content is 30-40% and the marked ISO 591 R2 pigment, whose content is 8-12%, is the main used white pigment with the content of titanium dioxide greater than or equal 95%, the oil absorption less than or equal 20g / 100g and the Reynolds coefficient of the reducing power equal to 1800.
