This part replaces YC/T 10.11-2006 "General Technical Conditions for Tobacco Machinery Part 11. Painting", and YC/T 10.11-Compared with 2006, the main technical changes except editorial changes are as follows.

--- Added terms and definitions, general content (see Chapter 3, Chapter 4);

--- Increased the content of the coating classification (see 5.1);

--- Increased the content of standard fasteners in the painted part, fully enclosed welded parts [see 5.2 f), g)];

--- Increased paint when the user does not require it (see 5.3.6);

--- Increased the coating of the inner surface of parts that need to be in contact with tobacco and other materials in the special parts or warning parts of the equipment.

Paint requirements [see g. 5.4.2), h), i), j)];

--- Removed the appearance of the paint film, the use of environmental conditions (see 2006 edition of 3.4, 3.5);

---In the surface treatment and quality requirements before painting, the roughness requirements of the coated parts and plastic parts, rubber parts, leather goods are increased.

Processing requirements for the pre-painting of pieces and wood products (see 5.6.6, 5.6.7, 5.6.8, 5.6.9, 5.6.10);

--- Increased ambient temperature, relative humidity, illuminance, dust permitting degree, ventilation and wind speed, and painting pressure in the painting process conditions Related requirements for air reduction (see 5.7.2, 5.7.3, 5.7.4, 5.7.5, 5.7.6, 5.7.7, 5.7.8, 5.7.9, 5.7.10, 5.7.11, 5.7.12) , 5.7.13, 5.7.14, 5.7.15, 5.7.16);

--- Separate the "painting requirements" into chapters (see Chapter 6, 3.9 of the 2006 edition);

---In the "priming requirements", the painting requirements for the surface of chemically or electrochemically treated workpieces are increased (see 6.1.5);

---In the "scratch putty requirements", the requirements of the paint grade on the putty and the requirements of the putty sequence are added (see 6.2.5, 6.2.6);

---In the "painting requirements", increased sanding requirements (see 6.3);

---In the "coating intermediate requirements", the painting requirements have been increased (see 6.4.3, 6.4.4, 6.4.5);

---In the "painting requirements", the painting requirements have been increased (see 6.5.3, 6.5.4, 6.5.5, 6.5.6);

---In the "painting requirements", increased waxing and polishing requirements (see 6.6);

--- Increased the requirements for quality inspection of the painting process (see 8.1);

--- Addition to the requirements of the appearance level and the use of environmental conditions (see Appendix A, Appendix B);

--- The informative appendix in the appendix was changed to a normative appendix (see Appendix C, Appendix A of the 2006 edition).

This part is proposed by the National Tobacco Monopoly Bureau.
