Foreword

Appendix A, Appendix B, Appendix C and Appendix D of this standard are normative appendices. This standard was proposed by the Agricultural Bureau of the Ministry of Agriculture. This standard is under the jurisdiction of the Ministry of Agriculture's Tropical Crops and Products Standardization Technical Committee. This standard was drafted by the South China Tropical Agricultural Products Processing and Design Institute. The Hainan Agricultural Reclamation Bureau and the Yunnan Agricultural Reclamation Bureau participated in the drafting. The main drafters of this standard.

1 Scope

This standard specifies the basic process and technical requirements for the production of rubber rubber for natural rubber radial tires. This standard is applicable to the use of fresh latex to assist bio-coagulation clots, rubber garden clots, artificial treatment of micelles as raw materials, or a certain ratio of these raw materials. For example, the production of radial tire rubber is blended.

After the glue is collected, the amount of ammonia should be added according to the actual amount of the latex. Control is within 0.05% (mass fraction). If conditions permit, try to add no ammonia or less ammonia. The latex solidified at the glue station or forest section should be Try not to add ammonia. 3.1.2.2 The quality of the latex should be strictly checked when the glue is collected. First remove the clots and debris in the latex, then use a pore size of 355μm (40 mesh). The stainless steel screen is filtered, filtered, and weighed and poured into a storage tank. The deteriorated latex can be naturally solidified and sent to the rubber factory for processing. 3.2 Collection of rubber garden clots 3.2.1 On the same day, the rubber-cutting workers should take back the fresh rubber garden clots from the forest section in time, and send them to the rubber-collecting station for sorting. 3.2.2 The glue collector shall send the collected rubber garden clots to the rubber factory in time. 3.2.3 Rubber garden clots that cannot be sent to the rubber factory in time due to special circumstances, must be placed in a cool place to prevent sun exposure and oxidative deterioration, oxygen Degraded rubber garden clots should not be used to produce radial tire rubber. 3.2.4 Manually processing the glue group in the forest section or the glue collection station should also be sent to the rubber factory in time.
