HG/T 2287-2001
This standard is a revision of the recommended chemical industry standard HG/T2287-1992 "Printing Rubber Roller" based on the production situation of printing rubber rollers and user needs.
Differences between this standard and HG/T2287-1992: The hardness tolerance and hardness difference of the same root of the printing rubber roller are adjusted. The dimensional tolerance grade of the printing rubber roller is improved. The physical properties of the rubber used for printing rubber rollers are partially adjusted, and the use requirements in Chapter 8 and Appendix C are combined as Appendix C of the standard. Appendix A, Appendix B, Appendix C, and Appendix D of this standard are the appendices of the standard. From the date of implementation, this standard will replace HG/T2287-1992 at the same time. This standard was proposed by the Policy and Regulations Department of the former State Administration of Petroleum and Chemical Industry, and this standard is under the jurisdiction of the National Rubber and Rubber Products Standardization Technical Committee and the Rubber Sundries Branch. The responsible drafting unit of this standard is Hebei Jizhou Chunfeng Yinxing Rubber Roller Co., Ltd. The participating drafting unit of this standard is Shandong Lihua Waterproof Building Materials Co., Ltd. The main drafters of this standard are Huang Tianye and Sun Xiaodong. This standard was first issued as a national standard in 1986 and adjusted to a recommended chemical industry standard in 1992. 229

Record card for rubber roller use
When loading and unloading rubber rollers, they should be handled with care and should not hit the roller neck and rubber layer. b.
The rubber rollers must be cleaned with a cleaning agent before and after use. If the rubber rollers are transferred to standby, they should be coated with anti-sticking agent after cleaning, and then wrapped with paper and placed on the rubber roller rack. The user unit should fill in the record card for each rubber roller in detail (see Table C1) and properly keep the manufacturer's inspection certificate, d.
so that it can be used for inspection when the rubber rollers are damaged in the early stage, otherwise the manufacturer has the right to refuse to accept it. Table C1 Rubber Roller Usage Record Card

Measurement steps
Install the rubber roller between the two tops (see Figure D1). Figure D1 Rubber roller circular runout tolerance measurement installation diagram D2.2 During one rotation of the rubber roller, the maximum reading value of the indicator is the single measurement value of the radial runout. D2.3 According to the above method, take at least 5 points on the surface that are approximately equidistant in the length direction, measure the radial runout of each point, and take the maximum value as the circular runout tolerance of the rubber roller.
