　　Respected Chinese Hudong Shipbuilding (Group) Co., Ltd. leadership:

　　You!

　　I am against your company's Secretary-term supply of a number of perlite, color, an unusual phenomenon, the proportion of occasional two sides agreed to the standard limit, after the Secretary for the Department of Technical and production quality of the joint analysis, the results are as follows:

　　1, this award perlite it contains trace black granular material, the analysis of products containing the Fe2O3, Al2O3 and K2O, and other ingredients. It was June 24 at the national non-metallic mineral processing engineering technology research center detected by physical and chemical testing, other chemical ingredients for the test results: SiO2 for 75.62%, Fe2O3 content of 0.84%, Al2O3 for 12.47%, K2O to 4.45%, Na2O for 2.38%, CaO to 0.80%, MgO to 0.16 percent. According to the requirements of GTT, chemical composition testing frequency for each three months time, the following criteria: SiO2 content equivalent to more than 71%, Al2O3 and Fe2O3 less than or equal to the total amount of 17%, CaO and MgO content of less than or equal to the total 2% Na2O and K2O content of less than or equal to total nine percent, test results and standards that GTT: This GTT approved products meet standard requirements, can be used normally. (With: GTT standards and testing of a report)

　　2, according to customer density in the industry standards can be done within the appropriate adjustments. If the client needs the whole batch of product density of light, can take the following measures: the first on the technology can increase the flow of natural gas, preheat the second time can be reduced so that the light changed products. Density to be increased, contrary to operate. Production when the product density control in the centre of this will ensure that the product density in the center around, not up to standard on-line or standard off the assembly line.

　　Hereby that the above two points, inappropriate, please Comments, thank you!

　　- Sincerely, I wish your company!
